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
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
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
Tumor types
– Breast, (Number 1 in women)
– Lung
– Kidney
– Myeloma
– Prostate
– Melanoma
– Gastrointestinal tumors
– Lynphoma
Cervical area 10%
Thoracic area 70%
Lumbosacral 20%
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
Pain
– Localized
– Radicular
– Severity
– Position changes
– Cough
– Weightbearing
– Valsalva maneuver
Weakness 75-85%
– May progress rapidly
– Bilateral
– Corresponds to the level of cord involvemnent
Spasticity
Hyperreflexia
Abnormal stretch reflexes
Extensor plantar response
Sensory loss
–Bowel dysfunction
–Bladder dysfunction
–Impotence
Thorough physical examination
– Palpation
– Gentle percussion over bony areas
– Neurologic exam
Laboratory data – Increased alkaline phosphatase may indicate bony involvement
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
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
Criteria:
–Primary tumor type
–Level of myelopathy
–Degree of spinal block
–Potential for neurologic reversibility
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
Radiation therapy
– If not a surgical candidate
– Incomplete block
– Severe deficits
– Relapse in area of prior radiation if short survival is expected
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
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
Chemotherapy
– May be given in highly sensitive tumors
– Always given with other modalities
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
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
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
Thorough assessment and early
MD/Provider notification of changes in
– Pain
– Sensory function
– Motor function
– Urinary function
– Bowel function
Maintenance of functional status
– Bowel program
– Bladder program
– Skin care
– Rehabilitation services
