Objectives

At the completion of this presentation the participant will be able to:

– Describe the most common cancers associated with cord compression

– Identify at least 2 symptoms associated with cord compression

– Describe the most appropriate nursing interventions for cord compression

Definition/Frequency

A mass effect from the tumor with associated edema which results in ischemia and neural damage to the spinal cord

10% of all patients with cancer will develop this complication

Occurrence

The most common source of cord compression is metastasis to the epidural space with or without bony involvement

Tumors can also through the reach the epidural space by direct extension through the intervertebral foramen

Some tumors occur in the cord itself

Etiology

Tumor types

– Breast, (Number 1 in women)

– Lung

– Kidney

– Myeloma

– Prostate

– Melanoma

– Gastrointestinal tumors

– Lynphoma

Level of Involvement

Cervical area 10%

Thoracic area 70%

Lumbosacral 20%

Symptoms

Back pain is usually the first symptom

95% of patients with a cord compression experience back pain

Pain will precede other symptoms by weeks to months

Early cord compression may be asymptomatic

Manifestations

Pain

– Localized

– Radicular

– Severity

– Position changes

– Cough

– Weightbearing

– Valsalva maneuver

Manifestations

Weakness 75-85%

– May progress rapidly

– Bilateral

– Corresponds to the level of cord involvemnent

Spasticity

Hyperreflexia

Abnormal stretch reflexes

Extensor plantar response

Manifestations

Sensory loss

–Bowel dysfunction

–Bladder dysfunction

–Impotence

Diagnosis

Thorough physical examination

– Palpation

– Gentle percussion over bony areas

– Neurologic exam

Laboratory data – Increased alkaline phosphatase may indicate bony involvement

Diagnosis

Radiographs- may reveal erosion of the pedicle,

– Lytic lesions of the vertebral body

– Collapse of the vertebral body

Bone scan- 20% of scans reveal lesions missed on plain films

CT

– Used to determine extent of tumor

Diagnosis

MRI ( Tool of choice)

– Able to determine prevertebral, vertebral, extradural, intradural, extramedullary and intramedullary lesions

– Provides better anatomic visualization with sagittal and axial images of the spinal cord

Fine needle aspiration

– May provide tissue confirmation

Treatment

Criteria:

–Primary tumor type

–Level of myelopathy

–Degree of spinal block

–Potential for neurologic reversibility

Treatment

Surgery

– Radical resection if an a candidate

– Complete block

– Single lesion where complete removal is possible

– Diagnosis is uncertain

– Mild deficits

– New data supports surgery over treatment with RT if patient is a good surgical candidate

Treatment

Radiation therapy

– If not a surgical candidate

– Incomplete block

– Severe deficits

– Relapse in area of prior radiation if short survival is expected

Treatment

Radiation- often initiated as an emergency if not a surgical candidate

– Therapy

Treatment field extends 1-2 vertebral bodies above and below level of compression

3000-4000 cGy over 2-4 weeks

2/3 of patients remain stable or improve

65-75% achieve pain relief

Treatment

Steroids

– Dexamethasone

Bolus IV 10 mg

Oral 4-6 mg q 6 hours for 2 days then a slow taper

25% of patients with cord compression require maintenance to maintain neurologic function

Steroid related side effects may occur

– Hyperglycemia

– GI bleeding

– Psychosis

Treatment

Chemotherapy

– May be given in highly sensitive tumors

– Always given with other modalities

Outcome

Pretreatment ambulatory ability is the main determinant of post treatment ambulatory ability

90% of patients ambulatory before therapy are after

Only 10% of paraplegics become ambulatory after therapy

Prognosis

Median survival is 6 months if patient presents as a paraplegic

50% of patients who walk in with a cord compression are alive at 1 year

If patient was ambulatory prior to RT survival is 8-10 months

Recurrent Disease

Options

– If RT given may be a surgical candidate if survival of > 12 months predicted

– Repeat RT

Risks of repeat RT

–Radiation myelopathy

–Collateral damage

Nursing Interventions

Thorough assessment and early

MD/Provider notification of changes in

– Pain

– Sensory function

– Motor function

– Urinary function

– Bowel function

Nursing Interventions

Maintenance of functional status

– Bowel program

– Bladder program

– Skin care

– Rehabilitation services
