CHAPTER 33. PALLIATIVE CARE EMERGENCIES
Roberta Kaplow
There are a number of emergent situations that can arise in patients with advanced disease. These can create circumstances that are stressful for the patient and family. It is vital that a multidisciplinary approach of care be developed for patients who are at risk to develop a palliative emergency. In every case, the decision whether to take emergency action must be based on the patient’s overall condition, the disease and its prognosis, the patient’s and family’s wishes, the potential side effects of treatment, and the distress caused by the emergency itself (Wrede-Seaman, 2001). This chapter discusses some common emergencies that can occur in the palliative care setting.
Many palliative emergencies are predictable from the nature and extent of disease. Therapies may be implemented to prevent and manage symptoms or to alleviate suffering. When intervention is inappropriate, prior discussion with patient and family of what may occur may avoid the stress of unexpected developments and the need for urgent decisions (Fowell & Stuart, 2005). The management of any event depends on the distress the symptoms are causing, the patient’s condition and quality of life, wishes of the patient and family, and possible treatment side effects (Fowell & Stuart, 2005; Gullatte, Kaplow & Heidrich, 2005; Kaplow & Reid, in press; Shuey & Brant, 2004).
HYPERCALCEMIA OF MALIGNANCY
Definition and Incidence
Hypercalcemia of malignancy (HCM) is defined as a serum calcium level greater than 10.5 mg/dl (Gullatte et al., 2005; Kaplow & Reid, in press).
The reported incidence of HCM is 10% to 40% of patients (Crossno, 2004; Gullatte et al., 2005; National Coalition for Cancer Survivorship [NCCS], 2005; Solimando, 2001).
Etiology and Pathophysiology
Etiologic factors of HCM include specific cancers, treatment modalities, and nonmalignant causes. HCM is most often associated with primary tumors of the breast, lung, head and neck, kidney, esophagus, gastrointestinal (GI) tract, and cervix; lymphomas; leukemia; multiple myeloma; and melanomas (Gullatte et al., 2005; Kaplow & Reid, in press; National Cancer Institute [NCI], 2005).
Cancer treatment modalities such as estrogen, antiestrogen agents, and all- trans retinoic acid are associated with the development of HCM (Gullatte et al., 2005).
Non–cancer-related factors associated with HCM development include immobility dehydration, excessive intake of calcium and vitamin D, decreased parathyroid hormone levels, vitamin A intoxication, hyperparathyroidism, and thiazide diuretic or lithium use (Carroll & Schade, 2003; Crossno, 2004; Gullatte et al., 2005; Kaplow, in press; NCI, 2005).
HCM most often results from bone metastasis. This causes osteoclastic bone resorption and release of calcium. Calcium is released from the bone faster than the kidneys can excrete it (Gullatte et al., 2005; Kaplow & Reid, in press). The types of HCM are osteolytic (results from direct bone destruction by a tumor or metastasis) and humoral (results from circulating factors secreted by cancer cells) (Carroll & Schade, 2003; Inzucchi, 2004; Kaplow, in press; NCI, 2005; Solimando, 2001).
History and Physical Examination
Clinical manifestations of HCM vary depending on effects of calcium on the neurologic, GI, renal, and cardiovascular systems; rate of the rise of calcium levels; and patient’s stage of disease and overall condition, renal function, and degree of HCM. They are usually related to the effects of calcium on smooth, skeletal, and cardiac muscle (Gullatte et al., 2005). Neurologic symptoms include mental status changes, hallucinations, jumbled speech, depression, and fatigue. Patients may report visual changes. Diminished deep tendon reflexes may be noted (Beckles, Spiro, Colice et al., 2003; Carroll & Schade, 2003; Crossno, 2004; Inzucchi, 2004; Kaplow & Reid, in press; NCI, 2005; NCCS, 2005; Shuey & Brant, 2004; Solimando, 2001).
Several cardiovascular symptoms exist. These include potential electrocardiographic changes such as prolonged PR interval, widened QRS complex, shortened QT interval, shortened or absent ST segments, and widened QT intervals. Patients may present with atrioventricular block bradycardia, bundle-branch block, or cardiac arrest, depending on severity. Hypertension and myocardial irritability may be observed (Beckles et al., 2003; Carroll & Schade, 2003; Crossno, 2004; Inzucchi, 2004; Kaplow & Reid, in press; NCI, 2005; NCCS, 2005; Shuey & Brant, 2004).
GI manifestations may include nausea, vomiting, anorexia, abdominal pain, ileus, constipation, abdominal distention, dry mouth, increased gastric acid production, pancreatitis, or peptic ulcer disease (Beckles et al., 2003; Carroll & Schade, 2003; Crossno, 2004; Inzucchi, 2004; NCI, 2005; NCCS, 2005; Shuey & Brant, 2004; Solimando, 2001).
Renal effects are polyuria, polydipsia, nocturia, renal failure, dehydration, and nephrogenic diabetes insipidus. Calcium phosphate crystals may be present in the renal tubules (Beckles et al., 2003; Carroll & Schade, 2003; Crossno, 2004; Inzucchi, 2004; Kaplow & Reid, in press; NCI, 2005; NCCS, 2005; Shuey & Brant, 2004; Solimando, 2001).
Other symptoms that may manifest in a patient with HCM include osteoporosis, arthritis, pathologic fractures, and pruritus (Beckles et al., 2003; Carroll & Schade, 2003; Crossno, 2004; Inzucchi, 2004; Kaplow & Reid, in press; NCI, 2005; Shuey & Brant, 2004; Solimando, 2001).
Diagnostics
Laboratory findings linked with HCM are abnormal serum creatinine, calcium, electrolytes, magnesium, phosphorus, and possibly elevated alkaline phosphatase (Crossno, 2004; Kaplow & Reid, in press; Shuey & Brant, 2004). The degree of HCM is determined by laboratory measurement of serum calcium in relation to serum albumin levels. Calcium levels should be corrected based on albumin levels, since 40% of calcium is bound to albumin (Gullatte et al., 2005; Kaplow & Reid, in press).
Intervention and Treatment
The primary treatment of HCM is treatment of the causal malignancy. This may require chemotherapy, radiation therapy (RT), hormonal therapy, and/or surgical resection (Gullatte et al., 2005; Kaplow & Reid, in press). Irrespective of severity, management should include treatment of any underlying non–disease-related causes.
Patients with a corrected calcium level less than 12 mg/dl may require only monitoring. Patients with moderate to severe HCM (more than 13 mg/dl) require aggressive treatment (Kaplow & Reid, in press).
Rehydration
Patients should drink 1 to 2 liters of fluid per day if able to tolerate oral fluids (Shuey & Brant, 2004). Patients with moderate to severe HCM may need 5 to 10 liters of fluid to restore extracellular fluid balance. Administration of isotonic saline may be required (Kaplow & Reid, in press). Loop diuretics should be avoided until volume status has been restored (Shuey & Brant, 2004).
Antiresorptive Therapy
Once rehydrated, patients require intravenous bisphosphonates. Bisphosphonates decrease the rate of bone resorption and prevent worsening or recurrence of HCM in patients with bone metastasis (Gullatte et al., 2005; Kaplow & Reid, in press; Ross, Saunders, Edmonds et al., 2004).
Corticosteroids
Patients with HCM due to steroid-responsive tumors may benefit from corticosteroid therapy. Glucocorticoids augment urinary calcium excretion and inhibit GI calcium reabsorption (Kaplow & Reid, in press; NCI, 2005).
Symptom Management
Management of HCM may also require symptom management and increasing mobility, as clinically indicated. If patients have been immobile for long periods of time, collaboration with physical therapy may be indicated (Kaplow & Reid, in press; Shuey & Brant, 2004). Constipation should be evaluated and treated. Bone pain must be managed but nonsteroidal antiinflammatory drugs (NSAIDs) should be avoided in patients using bisphosphonates (Gullatte et al., 2005). Some patients develop clinically significant and distressing mental status changes. Collaboration among physicians, midlevel clinicians, and pharmacy should focus on strategies to manage delirium or other such changes (Kaplow & Reid, in press).
Cardiac, renal, and GI function and electrolyte balance should be monitored during fluid resuscitation. This is especially important for patients who have heart failure or who have received cardiotoxic therapies. Monitoring serum creatinine is vital when receiving bisphosphonates because of the reported deterioration in renal function with these therapies (Gullatte et al., 2005).
Evaluation and Follow-up
The degree of monitoring required will depend on the patient’s condition and overall goals of care. Many side effects of treatment can be prevented or managed. Since serum sodium, potassium, calcium, phosphorus, and magnesium levels may decrease, levels should be monitored at least daily. Serum calcium levels will require monitoring, especially during bisphosphonate therapy. The management of symptoms and side effects is essential (NCI, 2005).
Patients treated for HCM will require close follow-up once normal calcium levels have been attained. The underlying malignancy, following its trajectory, may worsen and ongoing HCM management may be required (NCI, 2005; Shuey & Brant, 2004). Frequency of follow-up is also based on the anticipated lasting effect of the treatment modalities used (NCI, 2005).
Patient and Family Education
Patients and families require education regarding what symptoms to observe and the importance of reporting symptoms early. Measures can include preventing dehydration, weight-bearing activities, managing pain, and avoiding thiazide diuretics (Gullatte et al., 2005).
Patients and families should have the sequelae of untreated HCM explained to them; these include loss of consciousness and coma, which may be acceptable outcomes for patients at end-of-life who are suffering or have uncontrollable symptoms or when treatment of the underlying malignancy is no longer feasible (NCI, 2005).
SYNDROME OF INAPPROPRIATE ANTIDIURETIC HORMONE SECRETION
Definition and Incidence
Syndrome of inappropriate antidiuretic hormone secretion (SIADH) is a condition of water intoxication. It is depicted by inappropriate production and secretion of antidiuretic hormone (ADH). This causes increased tubular water reabsorption with subsequent water retention, dilutional hyponatremia, a decreased serum osmolality, and increased urine osmolality (Flounders, 2003; Kaplow & Reid, in press; Shirland, 2001). The secretion of ADH occurs despite adequate circulating fluid volume and urinary sodium excretion and (Beckles et al., 2003; Gullatte et al., 2005).
SIADH occurs in 1% to 14% of patients with malignancy. Patients with small-cell lung cancer (SCLC) have an incidence of up to 10% (Hemphill & Ismach, 2001; Kaplow, 2005; Kaplow & Reid, in press).
Etiology and Pathophysiology
The causes of SIADH are (1) cancer, (2) neurologic disorders, (3) benign lung disease, and (4) drugs (Baylis, 2003; Gullatte et al., 2005). SCLC is the most common cancer associated with the development of SIADH. Other associated malignancies are non–small-cell lung cancer (NSCLC); carcinoid tumors; squamous cell carcinoma of the head and neck; breast, brain, prostate, esophagus, pancreas, colon, thymus, uterus, bladder, ovarian, or duodenal tumors; neuroblastoma; mesothelioma; Hodgkin’s and non-Hodgkin’s lymphomas; and leukemia. It can also be caused by metastasis to the central nervous system (CNS) (Flounders, 2003; Gullatte et al., 2005; Kaplow & Reid, in press).
Some chemotherapeutic agents place patients at risk to develop SIADH. These include vincristine, vinblastine, cyclophosphamide, ifosfamide, cisplatin, and melphalan. Each of these agents can cause hyponatremia and elevated ADH levels (Gucalp & Dutcher, 2001; Gullatte et al., 2005; Kaplow & Reid, in press; Tan, 2002).
Non–cancer-related etiologic factors for SIADH include medications (e.g., opioids, antidepressants, NSAIDs, thiazide diuretics, barbiturates, and anesthetic agents), CNS disorders (e.g., brain abscess or herniation, hemorrhage, head trauma), and pulmonary disorders (e.g., infection, pneumonia, lung abscess, tuberculosis). Pain, stress, and nicotine have also been identified as causative factors (Flounders, 2003; Kaplow & Reid, in press; Tan, 2002).
Pathophysiology
SIADH results from a tumor secreting a protein similar to ADH. This protein is not responsive to normal body feedback mechanisms. SIADH may also be caused by chemotherapy provoking the posterior pituitary to secrete ADH. Both of these mechanisms cause inappropriate ADH secretion. When ADH is secreted, there is stimulation of water absorption in the distal tubules and collecting ducts. This results in decreased urinary excretion, concentration of urine, dilution of plasma, decreased serum osmolality, and dilutional serum hyponatremia (Kaplow & Reid, in press).
Assessment and Measurement
The symptoms depend on the degree and speed at which hyponatremia develops (Baylis, 2003). The hallmark signs of SIADH are hyponatremia, serum hypo-osmolality, and inappropriately concentrated urine for serum osmolality (Gullatte et al., 2005).
History and Physical Examination
Patients present with a variety of symptoms that may be due to dilutional hyponatremia, hypocalcemia, or hypokalemia. SIADH affects the CNS, GI, renal, musculoskeletal, cardiac, and respiratory systems. CNS symptoms include mental status changes, headache, ataxia hallucinations, agitation, fatigue, malaise, tremors, hyporeflexia, myoclonus, and unexplained seizures (Gullatte et al., 2005). GI symptoms may include nausea, vomiting, diarrhea, anorexia, and abdominal cramping. If the renal system is affected, the patient may manifest thirst, weight gain without edema, and oliguria. Musculoskeletal symptoms are muscle cramps and weakness. Patients may have hypotension or normal blood pressure and heart rate as well as fluid retention. Possible respiratory symptoms include inability to maintain a patent airway and inability to mobilize secretions (Baylis, 2003; Beckles et al., 2003; Flounders, 2003; Gullatte et al., 2005; Kaplow & Reid, in press; Tan, 2002). If a serum sodium level is less than 120 mmol/L and develops acutely, the patient is at risk for the development of cerebral edema (Gullatte et al., 2005; Langfeldt & Cooley, 2003).
Diagnostics
Diagnosis of SIADH is based on laboratory data and through the exclusion of other contributing factors of hyponatremia. The clinician should have a high index of suspicion based on the presence of risk factors in a hyponatremic patient (Gullatte et al., 2005; Janicic & Verbalis, 2003). Laboratory data consistent with a diagnosis of SIADH are a urinary sodium level of greater than 40 mEq/L, urinary osmolality greater than 1000 mOsm/kg, serum hypo-osmolality, and hyponatremia (Kaplow & Reid, in press).
Intervention and Treatment
Continuous monitoring of the patient is important to identify changes in clinical status. Assessment of fluid and electrolyte status and for side effects of treatment is equally essential. Collaboration among the physician, pharmacist, and nurse to manage anxiety and depression will help optimize patient outcomes, as many medications will need to be avoided (Flounders, 2003; Kaplow & Reid, in press).
Treatment of the underlying cause of SIADH may be implemented. Treatment modalities include chemotherapy, RT, and/or corticosteroids (Kaplow & Reid, in press). The foundation of management is fluid restriction to less than 800 to 1000 ml/day until serum sodium improves (Kaplow & Reid, in press; Flounders, 2003). Demeclocycline administration is recommended if fluid restriction alone is not effective (Gullatte et al., 2005; Kaplow & Reid, in press; Flounders, 2003; Tan, 2002).
Patients with acute hyponatremia and severe neurologic symptoms should receive 3% saline at a rate of 300 to 500 ml over 4 to 6 hours until a serum sodium of 125 mg/dl is attained (Crook, 2002). Serum sodium should be corrected at a rate of 0.5 to 2 mEq/h to prevent complications of therapy (Flounders, 2003; Gucalp & Dutcher, 2001; Gullatte et al., 2005; Kaplow & Reid, in press; Kozniewska, Podlecka, & Rafalowska, 2003). Loop diuretics are recommended to decrease urine concentration and promote urinary free water excretion (Gucalp & Dutcher, 2001; Gullatte et al., 2005).
The key to managing SIADH is early detection to prevent complications. Monitoring fluid status may require urine specific gravity, daily weights, serum and urine electrolytes, and strict intake and output (I/O). Patients receiving hypertonic saline require ongoing assessment for overcorrection and/or fluid overload. Neurologic assessment is essential as rapid changes in mental status may signify worsening hyponatremia and rapid changes in sodium (Gullatte et al., 2005).
Evaluation and Follow-Up
SIADH resolves in less than 3 weeks when treatment of the underlying cause has been successful. Symptoms often recur if there is tumor progression (Beckles et al., 2003; Flounders, 2003; Kaplow & Reid, in press). While patients are being treated, serum chemistries may be monitored on a periodic basis (Tan, 2002).
Patient and Family Education
Patients and family members should be taught signs and symptoms to observe for, actions to take, and when to seek medical attention. While the patient is receiving treatment of SIADH, comfort measures such as mouth care and administration of small amounts of ice chips may be given to combat the discomfort of thirst. Family members should also be taught to observe for changes in mental status (Flounders, 2003; Gullatte et al., 2005).
SUPERIOR VENA CAVA SYNDROME
Definition and Incidence
Superior vena cava syndrome (SVCS) results from obstruction of the superior vena cava (SVC). The blockage may be above or below the azygous vein from an intravascular clot, tumor in the right main upper lobe bronchus, or significant mediastinal lymphadenopathy. The obstruction impairs blood flow to the right atrium and venous drainage above the upper thorax. This results in a decreased venous return (Gullatte et al., 2005; Hemann, 2001; Kaplow & Reid, in press; Rowell & Gleeson, 2005; Wudel & Nesbitt, 2001).
An incidence of 2.4% to 21.1% of SVCS in lung cancer patients has been reported (Rowell & Gleeson, 2005).
Etiology and Pathophysiology
Most cases of SVCS are due to malignancy. Of these, 80% are due to NSCLC and non-Hodgkin’s lymphoma (Beckles et al., 2003; Kaplow & Reid, in press; Thirlwell & Brock, 2003). In patients with lung cancer, SVCS is usually due to direct extension or lymph node metastasis (Beckles et al., 2003; Kvale, Simoff, & Prakash, 2003). Some cases are due to breast or testicular cancer metastasis. T-cell leukemia causes mediastinal adenopathy and enlargement of the thymus, which can compress the SVC. Rare cases of SVCS are attributed to Kaposi’s sarcoma, esophageal cancer, thymoma, mesothelioma, and Hodgkin’s disease (Kaplow & Reid, in press).
Nonmalignant causes of SVCS include tuberculosis, indwelling central venous catheters or pacemaker wires, Silastic or dialysis catheters, aneurysm of the aortic arch, or constrictive pericarditis (Gullatte et al., 2005; Kaplow & Reid, in press).
Because of the location of the SVC (it is surrounded by structures that do not compress), the SVC’s thin walls, and the low presssure of blood flow in the SVC, when regional lymph nodes or the aorta enlarge, the SVC constricts effortlessly, and thus blood flow becomes sluggish and occlusion frequently occurs (Gullatte et al., 2005).
Assessment and Measurement
The signs and symptoms of SVCS are related to severity and location of the obstruction. It is usually not until the obstruction is complete that clinical manifestations become obvious. This makes the diagnosis of SVCS more challenging.
History and Physical Examination
Symptoms tend to be more severe when the obstruction is below the azygous vein (Rowell & Gleeson, 2005). The respiratory, cardiac, and CNS systems are affected. CNS manifestations include mental status changes, headache, dizziness (especially when leaning forward), blurred vision, and syncope. Respiratory symptoms are shortness of breath, dyspnea, hoarseness, cyanosis, cough, dysphagia, and stridor. Cardiac symptoms may include edema of the face, arm, and upper chest; dilated veins in the upper torso, shoulders, and arms; jugular venous distention; tachycardia; chest pain; and hypotension. Patients may present with erythema of the eyelids, tightness of the neck (Stokes sign), or periorbital edema (Beckles et al., 2003; Gucalp & Dutcher, 2001; Gullatte et al., 2005; Kaplow & Reid, in press).
Diagnostics
Radiology Findings
Both computed tomography (CT) and magnetic resonance imaging (MRI) help to determine the extent of the underlying tumor. A contrast-enhanced spiral CT scan can identify the obstruction site and presence of a thrombus. A venogram may be used to determine if the obstruction is due to stenosis or obstruction and the extent of a thrombus (Kaplow & Reid, in press; Rowell & Gleeson, 2005).
Chest CT can help locate mediastinal lymph nodes (Gucalp & Dutcher, 2001). A Doppler ultrasound can detect SVC obstruction if the patient cannot tolerate CT (Benenstein, Nayar, Rosen et al., 2003; Gullatte et al., 2005; Kaplow & Reid, in press).
Intervention and Treatment
Management of SVCS is designed for symptom management and treatment of the underlying cause. If the patient has adequate collateral circulation and symptoms are minimal, treatment may not be required (Hemann, 2001; Wudel & Nesbitt, 2001).
Patients with SVCS should be maintained with the head of the bed elevated. Oxygen therapy may be needed for dyspnea (Thirlwell & Brock, 2003). The patient should be protected from fluid overload. Upper extremity venous catheters should be avoided (Gullatte et al., 2005).
Routinely, management consists of steroids and either chemotherapy or RT. Steroids are usually given to patients receiving RT due to potential radiation-induced edema. If used, high-dose steroids should be given for a limited time period (Kaplow & Reid, in press; Rowell & Gleeson, 2005).
Radiation Therapy
If the patient develops respiratory distress, immediate RT is indicated. Almost 50% of patients report relief with RT. Positioning patients for RT may be problematic because many will have worsening dyspnea in the supine position (Gullatte et al., 2005).
Chemotherapy
Chemotherapy is indicated for chemosensitive tumors. Patients report symptom relief in 7 to 10 days, and many report complete resolution of symptoms within 2 weeks (Gucalp & Dutcher, 2001; Gullatte et al., 2005; Kaplow & Reid, in press; Thirlwell & Brock, 2003).
Diuretic Therapy
Diuretics may be used in patients with SVCS with airway edema (Kaplow & Reid, in press; Rowell & Gleeson, 2005). Use of diuretics may also decrease right-sided preload, which will decrease pressure on the SVC. Diuretics should be avoided in patients who have a pericardial effusion or cardiac tamponade. Furosemide is used most often (Gullatte et al., 2005).
Endovascular Techniques
Endovascular techniques, such as thrombolysis, angioplasty, or stenting, can be done in conjunction with antineoplastic therapies (Kaplow & Reid, in press). The former should be initiated if the cause of the obstruction is a thrombus. Best results with thrombolytics are seen in patients who are treated within 2 days (Gullatte et al., 2005). Anticoagulation is used in conjunction with thrombolysis (Kaplow & Reid, in press). SVCS related to central catheters warrants catheter removal and anticoagulant therapy (Gullatte et al., 2005; Thirlwell & Brock, 2003). Placement of expandable metallic stents into the SVC has been done to reopen the SVC. This has resulted in return of normal blood flow and resolution of symptoms in most patients (Thirlwell & Brock, 2003). Balloon angioplasty may be used to enlarge a vessel lumen for stent placement (Kvale et al., 2003).
Ongoing monitoring and maintenance of a patent airway are vital for a patient with SVCS. Although rare, it is possible for the patient to develop airway compromise or tracheal obstruction (Gullatte et al., 2005; Kaplow & Reid, in press). Airway management strategies are indicated. Some temporary relief from dyspnea may occur with upright posture and oxygen (Gucalp & Dutcher, 2001; Gullatte et al., 2005; Thirlwell & Brock, 2003). Suction equipment should be readily available at the patient’s bedside.
Corticosteroids
Glucocorticoids may decrease edema surrounding the tumor (Thirlwell & Brock, 2003). Dosage should be tapered as symptoms resolve (Gullatte et al., 2005).
Surgery
Surgery is mostly indicated for benign causes of SVCS (Thirlwell & Brock, 2003). It is performed to bypass and relieve the pressure associated with an obstructed SVC (Gullatte et al., 2005).
Patients classically present with anxiety from respiratory distress, poor prognosis, or body image changes. Administration of sedatives that do not act on the CNS and provision of a quiet environment, emotional support, and reassurance may help allay anxiety (Kaplow & Reid, in press).
Evaluation and Follow-Up
Patients are at risk for bleeding from thrombolytic therapy, anticoagulation, perforation, or hematoma from endovascular procedures. Interventions that are indicated for this include monitoring complete blood cell count and coagulation profiles and maintaining bleeding precautions. If possible, avoid use of a blood pressure cuff on the arm (Kaplow & Reid, in press).
Patients are also at risk for infection from antineoplastic therapy, steroids, or endovascular procedures. They should have their white blood cell count monitored and be considered for prophylactic antibiotics. There is also a potential for dehydration, electrolyte imbalance, and hypotension from diuretic therapy. Monitoring fluid and electrolyte balance, vital signs, and strict I/O are essential (Kaplow & Reid, in press).
The 30-month mortality rate of SVCS is 90%. Relief of symptoms is likely within 1 month of the onset of RT (Gullatte et al., 2005).
An 11% recurrence rate has been reported with stent insertion. A low incidence of complications is reported with stents, especially when thrombolytics are used (Kaplow & Reid, in press; Rowell & Gleeson, 2005).
Patient and Family Education
Patient and family education is needed to increase knowledge of subtle signs and symptoms of SVCS. The patient and family should be taught to observe for complications related to stent placement; these include bleeding from vascular injury and thrombosis within the stent (Kvale et al., 2003). Patients and family members should be taught what to report to their physician so that early treatment can be initiated, if indicated.
SPINAL CORD COMPRESSION
Definition and Incidence
Spinal cord compression (SCC) is compression of the thecal sac by a tumor. The compression may be located in the spinal cord or at the level of the cauda equina (Flounders, 2003; Kaplow & Reid, in press; Quinn & DeAngelis, 2000).
Data suggest that 0.2% to 30% of patients with cancer can develop SCC (Crossno, 2004; Kvale et al., 2003; Loblaw, Laperrier, & Mackillop, 2003; Pease, Harris, & Finlay, 2004; Purdue, 2004, Osowski, 2002). There is an incidence of 10%, 70%, and 20% in the cervical, thoracic, and lumbosacral spine, respectively (Crossno, 2004; Kaplow & Reid, in press).
Etiology and Pathophysiology
SCC often results from metastatic tumors. The most frequently reported tumors are lung, breast, and prostate. Others include lymphoma, melanoma, GI cancers, seminoma, neuroblastoma, sarcoma, myeloma, and renal cell carcinoma. Patients with primary cancers of the spinal cord are also at risk (Founders & Ott, 2003; Gucalp & Dutcher, 2001; Gullatte et al., 2005; Kaplow & Reid, in press; Tan, 2002).
SCC is classified as either intramedullary (within the spinal cord), intradural (within the dura mater), extramedullary (outside the spinal cord), or extradural (outside the dura mater) (Kaplow & Reid, in press). The latter is the most common type (Founders & Ott, 2003; Tan, 2002). Tumors usually arise from the anterior vertebral body and extend into the epidural space, compressing the spinal cord and vasculature and leading to ischemic damage to motor and sensory pathways and associated gray matter (Gullatte et al., 2005). The tumor applies pressure on the spinal cord, affecting its blood supply. This can lead to infarction or vertebral collapse. When a tumor spreads to the spinal cord, it breaks up the vertebral body, causing it to collapse. The spinal cord compresses as tumor or particles of bone are pushed into the epidural space (Founders & Ott, 2003; Kaplow & Reid, in press).
Most tumors spread to the spinal cord as an embolic process. CNS cancer can also spread to the cerebrospinal fluid. This results in spread to the subarachnoid space, brain, and spinal cord (Founders & Ott, 2003). As the cancer spreads, edema of the tissues and nerves, ischemia, neural distortion, and tissue death result (Kaplow & Reid, in press; Tan, 2002).
History and Physical Examination
Presentation of SCC varies, depending on location and extent of the compression, cause, blood supply involvement, and rapidity of development. Effects can be sensory, motor, and/or autonomic (Founders & Ott, 2003; Gullatte et al., 2005; Kaplow & Reid, in press).
Motor Symptoms
Patients most frequently report back or neck pain (Crossno, 2004; Founders & Ott, 2003; Kaplow & Reid, in press). Pain may be localized at the site of the tumor and is constant, dull, or aching. Pain may also be radicular or medullary, which may intensify over time and when lying supine (Founders & Ott, 2003; Gullatte et al., 2005). The pain may develop slowly over months before other neurologic symptoms occur or quickly, over hours, before complete, irreversible damage occurs to the spinal cord (Crossno, 2004). Patients may also report pain on coughing or sneezing, a sudden change in pain, or pain that waxes and wanes. Patients may further report unilateral or bilateral radiating leg pain (Kaplow & Reid, in press; Spinal Cord Compression, 2005).
Motor symptoms may also include easy fatigue, gait disturbance, lower extremity weakness, ataxia, loss of coordination, hypotonicity, and hyporeflexia (Founders & Ott, 2003; Kaplow & Reid, in press; Kvale et al., 2003). Weakness usually occurs over some time following pain and begins in the feet and moves proximally (Crossno, 2004; Spinal Cord Compression, 2005). Patients with compression of the cervical spine will have quadriplegia. Patients with compression of the thoracic spine have paraplegia.
Sensory Symptoms
Sensory changes usually begin distally and rise to the level of the compression. When a patient has compression of the cauda equina, there is bilateral sensory loss. Sensory symptoms include paresthesias, severe pain, sensory loss to level of compression, decreased light touch, joint, position sense, and proprioception, numbness, loss of thermal sense, loss of deep pressure sensation, loss of vibration sensation, decrease in strength, and Lhermitte’s sign. Sensory changes progress if interventions are not initiated. Weakness and sensory abnormalities are late findings and are frequently irreversible (Founders & Ott, 2003; Gullatte et al., 2005, Kaplow & Reid, in press; Kvale et al., 2003; Tan, 2002).
Autonomic Symptoms
Patients usually experience sensory and motor symptoms prior to autonomic dysfunction. Autonomic symptoms include impotence, changes in bowel and bladder function, hesitancy, urinary retention or incontinence, lack of urge to defecate or bear down, constipation, decreased anal tone, and bladder distention (Founders & Ott, 2003; Gullatte et al., 2005, Kaplow & Reid, in press; Kvale et al., 2003; Tan, 2002).
The most vital data to assist in the diagnosis of SCC are the patient history and clinical evaluation (Arch, Sass, & Abul-Khoudou, 2001). A complete history, physical, and neurologic assessment, as well as evaluation of pain, sensory, motor, and autonomic function are essential. It is vital that reported back or neck pain be meticulously evaluated because the strongest predictor of a patient with SCC is neurologic status upon presentation. A patient’s ability to ambulate upon diagnosis will significantly predict ability to ambulate following treatment (Founders & Ott, 2003; Kaplow & Reid, in press).
Patient history should include determination of presence and characteristics of symptoms. Complete examination of the neurologic and musculoskeletal systems is imperative in any patient who is at risk for development of SCC and who is symptomatic. The patient performs a straight leg raise. If radicular pain is present, it increases with this movement. Sharp pain on dorsiflexion suggests nerve root compression (Founders & Ott, 2003; Kaplow & Reid, in press).
Sensory evaluation should be conducted (Founders & Ott, 2003). The area of sensory loss can determine the level of the compression. Positive sensation is usually one or two levels below the site of the compression (DeMichele & Glick, 2001; Founders & Ott, 2003). The patient will usually report tenderness to percussion at the site of the compressed vertebrae (Crossno, 2004; Kaplow & Reid, in press).
Patients should be evaluated for gait disturbances, muscle strength, involuntary movements, and coordination. A patient’s tendon reflexes are increased below the compression, absent at the level of the compression, and normal above the level of the compression (Founders & Ott, 2003; Kaplow & Reid, in press).
Autonomic dysfunction requires further evaluation, as it is a poor prognostic indicator (Gullatte et al., 2005; Kaplow & Reid, in press).
Respiratory distress may occur if the patient has a cervical compression. Evaluation for declining oxygenation and ventilation is pivotal, especially in patients with tumor involvement at the C4 level or above (Kaplow & Reid, in press).
Diagnostics
Radiology Findings
A spinal radiograph is the initial diagnostic study for SCC. It may be normal or may reveal fracture, damage or erosion to vertebrae, and any lesion in up to 85% of the vertebrae (Founders & Ott, 2003; Gullatte et al., 2005; Kaplow & Reid, in press; Spinal Cord Compression, 2005; Spinal Cord Trauma, 2005). It may also detect presence of epidural metastasis (Crossno, 2004). It will not detect early SCC, as 50% of bone must be destroyed for it to be viewed (Founders & Ott, 2003; Kaplow & Reid, in press).
MRI of the spine is used to establish the precise location of the compression, evaluate extent of spinal involvement, and determine the presence of vertebral tumors (Crossno, 2004; Gullatte et al., 2005). It is also useful to visualize soft tissue, the spinal cord, and the cauda equina. The entire spine should be visualized, since metastasis can occur in multiple sites. Either MRI or CT scan may identify the location and extent of spinal cord trauma. It can also be used to assess for bone destruction. A myelogram may be done as well (Founders & Ott, 2003; Kaplow & Reid, in press; Spinal Cord Trauma, 2005).
CT with contrast will detect paraspinal masses and early lesions. It may verify SCC and fully determine the level and extent of the lesion. Positron emission tomography can confirm data received from MRI or CT. Bone scan may show extent of bone involvement and spinal level 20% of the time and detect abnormalities not detected on radiograph (Founders & Ott, 2003; Gullatte et al., 2005; Kaplow & Reid, in press; Levack, Graham, Collie et al., 2002).
Intervention and Treatment
Treatment options include surgery, steroids, RT, and chemotherapy. Goals of therapy are to provide pain relief, restore neurologic function, possibly treat the underlying malignancy, and prevent permanent disability. Management depends on the type of underlying tumor, location, and characteristics (Founders & Ott, 2003; Gullatte et al., 2005; Kaplow & Reid, in press; Osowski, 2002).
Radiation Therapy
RT is the definitive treatment for SCC and is administered in fractionated doses over a 2- to 4-week period (Gullatte et al., 2005; Tan, 2002). The area that is radiated usually extends one or two vertebrae above and below the compression (Founders & Ott, 2003). RT is used to minimize the size of the tumor, to decompress the spinal cord, and to provide pain relief. Around 85% of patients report pain relief with RT (Kaplow & Reid, in press).
Surgery
Surgery should be the first line of therapy in patients with spinal instability, bony compression, or paraplegia on initial presentation. It may be used to alleviate pain and stabilize the spine. Surgery is also indicated for (1) rapidly declining neurologic function, (2) compression occurring in a previously radiated field, (3) progressive neurologic deficits during radiation, (4) when the underlying tumor will not respond to RT, or (5) if the area has already been treated with RT (Bartanusz & Porchet, 2003; Crossno, 2004; Founders & Ott, 2003; Gullatte et al., 2005; Kaplow & Reid, in press; Kvale et al., 2003; Maranzano et al., 2003).
Corticosteroids
Steroids are commonly used initially until treatment of the underlying cause can begin (Crossno, 2004; Founders & Ott, 2003). They are used to decrease edema, inflammation, and pain (Gullatte et al., 2005; Kaplow & Reid, in press). For patients who are not paretic and ambulatory, high-dose steroids and RT are recommended (Kaplow & Reid, in press; Kvale et al., 2003).
Chemotherapy
Patients with chemosensitive tumors may benefit from chemotherapy to treat the underlying malignancy. Chemotherapy may also be used in patients who are not candidates for RT or surgery. Hormonal therapy may help patients with breast or prostate cancer (Gucalp & Dutcher, 2001; Gullatte et al., 2005; Kaplow & Reid, in press).
Evaluation and Follow-Up
When patients with SCC are discharged from the hospital, determination should be made of the need for ambulatory care, visiting nurses, or hospice care (Flounders, 2003). Paralysis or numbness of part of the body is common in patients with SCC. Death is also a possibility if the diaphragm becomes paralyzed (Spinal Cord Trauma, 2005). If a patient has neurologic deterioration or recompresses after undergoing RT, additional RT can be considered. Patients may continue to require physical therapy. Monitoring should include assessment for side effects that can occur with high-dose steroids.
Patient and Family Education
The patient and family must be educated about signs of SCC to report so that treatment can begin when indicated (Loblaw et al., 2003). If the patient is at risk for the development of SCC, the patient and family should be taught to report any new or increase in back pain. The patient and family member should be taught when to call the physician. They should also be taught about side effects of treatment to monitor (Flounders, 2003; Kvale et al., 2003; Osowski, 2002).
HEMORRHAGE
Definition and Incidence
Hemorrhage refers to blood loss that is striking and sudden. The incidence of hemorrhage in the palliative care setting is difficult to quantify, since it depends on the cause. It has been found that 20% of patients with a recurrent cancer will sustain a catastrophic bleed. In the case of advanced head and neck cancer, hemorrhage can account for 11.6% of deaths. In one study, 5% of patients died of a carotid artery rupture (British Association of Head and Neck Oncology Nurses [BAHNON], 2005). In a study of patients with acute myeloid leukemia, 44% of patients in the final phase had episodes of bleeding noted (Stalfelt, Brodin, Pettersson et al., 2003).
Etiology and Pathophysiology
Patients at risk for the development of hemorrhage are those with head and neck cancer, hematologic malignancies, or any malignancy that is adjacent to a major artery, thrombocytopenia, or coagulopathies. Patients with bladder cancer, hepatocellular carcinoma, or cirrhosis are also at risk (Letier, Krige, Lemmer et al., 2000; Shah, Mumtaz, Jafri et al., 2005; Textor, Wilhelm, Strunk et al., 2000; Uemura, Matsusako, Numaguchi et al., 2005). Any patient who has undergone surgery for head and neck cancer in areas adjacent to the carotid artery is a potential candidate (Casey, 1988; Cohen & Rad, 2004; Freeman et al., 2004). Hemorrhage is a complication of a radical neck dissection (Rodriguez, Carmeci, Dalman et al., 2001). This is especially so if the patient has received RT to the area (Cohen & Rad, 2004). RT to the neck is the most common factor leading to carotid artery rupture (Cohen & Rad, 2004; Rodriguez et al., 2001). Patients may also develop carotid artery rupture related to direct tumor invasion leading to damage to the arterial wall (BAHNON, 2005).
With head and neck cancer, hemorrhage may occur either externally from the neck, internally from within the oropharynx, or directly into the airway or tracheostomy (Cohen & Rad, 2004; Lovel, 2000).
There are several pathophysiologic reasons for a patient to develop hemorrhage. These include vessel injury, platelet dysfunction, coagulopathies (e.g., disseminated intravascular coagulation), and changes in viscosity of blood. If a tumor invades a blood vessel, significant and sudden blood loss can occur. Bone marrow failure or tumor invasion into the bone marrow can cause thrombocytopenia. If the patient develops liver failure, bleeding problems may ensue. Several medications can also lead to hemorrhage as a side effect (Heidrich & McKinnon, 2002).
Assessment and Measurement
Patients should be assessed for risk of bleeding based on past medical history. Factors to consider include type and location of malignancy. Patients with head and neck or GI malignancies are at the highest risk for hemorrhage. Patients who have received chemotherapy or RT are at risk due to myelosuppressive toxicities of these therapies. Surgical patients may also be at risk depending on the extent of the procedures. In addition, tumors themselves can disturb vasculature, placing the patient at risk for hemorrhage (Heidrich & McKinnon, 2002).
History and Physical Examination
A complete history may assist the clinician to identify patients at risk for hemorrhage. A patient history should include determination of whether the patient has had bleeding from any site in the past, degree of bleeding, and what interventions were used. The location of tumors, history of antineoplastic therapies and dates of these therapies, any hepatic dysfunction, and the patient’s medication profile will all provide clues for the risk of hemorrhage (Heidrich & McKinnon, 2002).
Patients with minor bleeding from a wound, a flap site, a tracheostomy, or the mouth may hemorrhage. This is caused by a small rupture of the intima (BAHNON, 2005). Some patients manifest ‘pulsations’ from artery or tracheostomy or flap site, or report sternal or high epigastric pain several hours before rupture Some patients develop ‘ballooning’ of an artery prior to carotid artery rupture (BAHNON, 2005; Lovel, 2000).
Diagnostics
Laboratory tests may provide clues as to the etiology of hemorrhage. These include platelet count, coagulation profile, and liver function tests. Determination of any herbal or over-the-counter remedies that the patient has taken may help identify the cause as well (Heidrich & McKinnon, 2002).
Intervention and Treatment
There are only a small number of alternatives to treat a patient in the palliative care setting who is hemorrhaging (Puetz & Bourhasin, 2002). Much of the data reported are in the form of case studies rather than clinical trials.
The patient’s coagulation profile and platelet count should be monitored. If the patient is receiving anticoagulants, these will need to be adjusted. Administration of blood products may be considered, but this can pose a challenge in the home or hospice setting. A case report describes the use of an agent, recombinant factor VIIa, that was effective in the palliative care setting (Puetz & Bourhasin, 2002).
Some patients with head and neck cancer have a particular event to achieve and wish to avoid imminent death. For these patients, additional head and neck surgery may be attempted to decrease the likelihood of a bleed. However, there are risks associated with the surgery that warrant consideration. Ligation of the involved artery to avoid carotid artery rupture carries a mortality risk of 32% to 77%, and 12% to 50% of survivors experienced permanent neurologic defects (BAHNON, 2005). Endovascular embolization of the carotid artery is considered an alternative method to avoid carotid artery rupture. This procedure has a lower (0% to 10%) mortality rate and fewer (10%) patients have neurologic damage (Luo, Chang, Teng et al., 2003). Superselective embolization with a substance, Ethibloc (Ethicon, Inc., Somerville, NJ), has been reported in the literature. This procedure was recommended for use as palliative treatment for select patients with advanced head and neck cancer (Sittel, Gossman, Jungehulsing et al., 2001).
Intraarterial embolization therapy is suggested as a treatment option for patients with urinary bladder hemorrhage from bladder cancer. Intraarterial chemoperfusion with mitoxantrone may also be effective, depending on the acuity of the bleeding (Textor, Wilhelm, Strunk et al., 2000).
Management of GI bleeding is dependent on the source. For the patient with cancer, it may require a multidisciplinary approach with a medical, surgical, and radiation oncologist (Imbesi & Kurtz, 2005). Strategies to control bleeding may include combined treatment of sclerotherapy and octreotide infusion over 48 hours for patients with acute variceal bleeding resulting from cirrhosis, or sclerotherapy alone in patients with acute variceal bleeding from hepatocellular carcinoma (Letier et al., 2000; Shah et al., 2005).
One case report describes relief of pain in a patient with hepatocellular carcinoma with hemorrhagic metastasis. This patient received percutaneous sacroplasty with combined injections of bone cement and n-butyl cyanoacrylate (Uemura et al., 2005).
In the event of hemorrhage, it is essential that a clinician remain with the patient, avoid panicking, and call for help. Towels should be applied to the bleeding site for absorption, if possible. If the patient has a tracheostomy, inflate the cuff to avoid choking. Gentle suctioning to the mouth and tracheostomy site should be applied as necessary to avoid sensation of choking, since this may add greatly to distress (BAHNON, 2005).
Patients should be spoken to gently and calmly, and attempts should be made, if possible, to keep the patient in one place. It is important to be aware of family presence and needs. It is ideal to determine in advance whether the family wishes to stay with the patient and important to be respectful of their wishes. If the family elects to stay with the patient, it is vital to ascertain that support is given (BAHNON, 2005).
The patient experiencing hemorrhage should be sedated. Administration of intravenous midazolam has the most rapid onset. If the patient does not have intravenous access, subcutaneous or intramuscular administration is possible. The dose may then be titrated until the patient is fully sedated (BAHNON, 2005).
Evaluation and Follow-Up
Witnessing a hemorrhage can be very frightening for the family. Families should be referred to a counselor for support following such an episode. In addition, steps to prevent hemorrhage or minimize blood loss should be undertaken (Heidrich & McKinnon, 2002).
Patient and Family Education
Although the risk for major hemorrhage is very rare, the fear is very realistic and present for the patient and family. If the patient is at risk for major hemorrhage, the patient and family must be prepared for this possibility (Feber, 2000). Management of the bleeding and treatment will depend on decisions made between the patient and family. If the patient’s life expectancy and quality of life warrants, management of hemorrhage consists of general resuscitative measures, such as volume replacement and specific measures to stop the bleeding. If the patient’s goals are palliative, management may include measures to stop bleeding without full resuscitative measures. Comfort measures only may be most appropriate for end-stage patients (Pereira & Phan, 2004).
Medication should be available in event of the emergency. For patients at home, where intravenous access is not possible, families can be taught how to administer injectable midazolam. If family members do not feel able to do this, an alternative is rectal diazepam (BAHNON, 2005).
The family should be advised to have equipment such as dark towels, gloves, and buckets readily available. The patient should be encouraged to wear dark undergarments or pads. Use of green or blue toilet disinfectant is recommended to disguise blood loss (depending on the site of bleeding) if the patient or family is frightened (North Cumbria Palliative Care, 2005).
SEIZURES
Definition and Incidence
A seizure is a symptom of irritation to the CNS resulting in excessive and abnormal neuronal discharges. An acute seizure refers to 5 minutes or more of either continuous seizures or two or more seizures between which there is incomplete return to consciousness (Regional Palliative Care Program [RPCP], 2005).
Etiology and Pathophysiology
Patients at risk for the development of seizures are those with primary or metastatic cerebral tumors. Cancers that metastasize to the brain include breast, lung, melanoma, kidney, leukemia, and lymphoma. Leptomeningeal disease and AIDS have been implicated as well (Fox, 2001; RPCP, 2005; Vaicys & Fried, 2000). Patients with HIV/AIDS may develop seizures secondary to opportunistic infection (Papadakis & McPhee, 2005). Seizures reportedly occur in 25% to 30% of patients with cerebral cancer (RPCP, 2005).
Noncancer causes of seizures include metabolic alterations, infection, medications, drug withdrawal, intracranial hemorrhage, increased intracranial pressure, SIADH, encephalopathy, and hypoxia (Paice, 2001).
A seizure occurs when a large number of neurons discharge in an unusual manner. This results in paroxysmal behavioral changes. The two types of seizures described in the literature are generalized and focal. Generalized seizures involve large portions of the brain, whereas focal seizures involve specific areas of the brain (Paice, 2001).
History and Physical Examination
Patients with a history of seizures or untreated myoclonus are at risk to develop seizures (RPCP, 2005). A review of the medications the patient has received may provide valuable information. Patients should also be questioned regarding use of recreational drugs (Paice, 2001).
A complete history should be taken to determine what symptoms were present upon the start of seizure activity, the type of seizure activity, and presence of an aura before the seizure started (Paice, 2001).
Diagnostics
Laboratory tests should include assessment for hypoglycemia and electrolyte abnormalities. Renal and liver function tests should also be assessed (Papadakis & McPhee, 2005). If the patient is currently receiving anticonvulsants, obtaining serum levels may be indicated to determine if the medication is being absorbed (Paice, 2001).
Electroencephalography can be performed to help classify seizure activity and presence of a seizure disorder. MRI can be done if there are focal neurologic signs or symptoms, focal seizure, or focal electroencephalographic imbalance (Papadakis & McPhee, 2005). If the patient has a brain lesion, evaluation may be accomplished with either MRI or CT scanning (Paice, 2001).
Intervention and Treatment
Prophylactic measures are usually recommended in patients who have had a seizure. Phenytoin and phenobarbital are the most commonly used anticonvulsants. Valproic acid is the second most common medication used. Management of actual seizures includes administration of medications. A benzodiazepine or phenytoin may be used. If patients are unable to tolerate oral medications, phenobarbital may be administered subcutaneously. Although rare, if seizures persist, a continuous subcutaneous midazolam infusion may be used (RPCP, 2005).
While having a seizure, the patient should be protected from self-injury, turned on the side, and provided with oxygen if applicable. If hypoglycemia is the cause of the seizure, the patient should receive intravenous glucose (RPCP, 2005).
Evaluation and Follow-Up
If the patient develops medication side effects before reaching therapeutic levels of the agent, it is recommended that the dosage be decreased or an alternative agent be tried. If the patient continues to have seizures and is free of side effects but has a high serum concentration of the agent, a higher dose of medication should be administered (RPCP, 2005).
Patient and Family Education
If a patient is at risk for the development of seizures, the patient and family should be informed of this likelihood. They should be taught what to observe for and expect and interventions that can be implemented (RPCP, 2005). Like the sight of blood, seizures can be very frightening, but they can be managed at home by family members who can be taught to give the patient medication. Family members should also be taught that a seizure is brief and self-limited and that it is rarely the patient’s cause of death. Family should be instructed to call the physician once the seizure activity has stopped (RPCP, 2005).
Family members should be taught to remove items that might cause harm to the patient during the seizure and the placement of pillows in strategic places to prevent trauma. They can also be shown ways to protect the patient’s airway during the seizure and to refrain from giving the patient anything orally until full consciousness is restored after the seizure (Paice, 2001).
Patients may benefit from an environment low in stimulation while recovering from the seizure. They should be spoken to softly and with reassurance (Paice, 2001).
CONCLUSION
In the case of palliative emergencies, management includes making the patient comfortable, preventing suffering, thinking of the needs of family members observing the event, explaining what is happening and management strategies being taken, and communicating reassurance to the patient and the family. Emergent interventions are determined on an individual basis.
L.C. is a 53-year-old woman who presents with dull, aching back and neck pain present for the past 2 weeks. She attributes it to “sleeping funny.” The pain has been constant but tolerable up until now. The patient’s past medical history includes breast cancer for which she underwent a modified radical mastectomy and chemotherapy 3 years ago. Six weeks ago she learned that the cancer had recurred and that additional therapy was required. The patient is receiving additional doxorubicin and cyclophosphamide.
Physical examination by the clinician reveals fatigue and weakness. A detailed neurologic examination was negative for leg pain, gait disturbance, loss of coordination, paresthesias, changes in proprioception, loss of thermal sense, loss of deep pressure sensation, loss of strength, and autonomic symptoms. Reflexes are normal.
Results of serum chemistries and coagulation profile are within normal limits. Complete blood cell count is significant for mild pancytopenia; white blood cells = 3.1, hemoglobin/hematocrit = 10.2/31, platelets = 103.
Spinal radiograph shows damage to T5-6 vertebrae. MRI revealed compression and presence of a tumor at the level of the fourth thoracic vertebra.
In collaboration with the oncologist and radiation oncologist, 4000 cGy of RT in fractionated doses is delivered over 4 weeks with the result of good pain relief. She is also given a loading dose of dexamethasone with subsequent tapering. Given the metastatic nature of her cancer and the poor prognosis of spinal cord compression (SCC), the patient did not opt for surgery to relieve the compression and decided not to continue chemotherapy. She is satisfied with her pain relief and has requested hospice care. She is ambulatory upon discharge from the hospital.
This case illustrates the clinician detecting a sign of SCC. The patient was given a comprehensive neurologic examination because of her medical history. It is essential to evaluate back and neck pain in any patient at risk for SCC, even if pain is the only presenting symptom. The prompt assessment and intervention by the NP allowed the patient to obtain pain relief and sustain no additional disabilities from the compression. She was discharged to hospice care, as requested.
