The Management of Malignant Spinal Cord Compression Dr H. K. Lord Consultant Clinical Oncologist

Aim – ambulatory patients

Introduction u 2 -5% of cancer patients have an episode of SCC u Commoner in myeloma, prostate, lung and breast cancer (15 -20%) u Initial presentation in 8% cancer patients, sometimes of unknown primary u 10% of patients diagnosed with SCC may have a second episode

Presentation u Depends u Radicular on level (77% in T spine) (1) back pain in 85 -95% u Worsened by lying flat, weight bearing, coughing and sneezing, relieved by sitting 1.

Millan N, Rampling R, Slider L, Statham P, Summers D (2001) A prospective audit of the diagnosis, management and outcome of malignant spinal cord compression. Clinical Resource and Audit Group (CRAG) 97/08

Presentation u Motor weakness u Sensory disturbance u Sphincter disturbance u However localisation of pain poorly correlates with site of disease – 16%

Aetiology 3 routes: u Vertebral mets invading the epidural space, or causing bone destruction and fragments of bone compressing the cord u Retroperitoneal tumours grow through the intervertebral foramina u Compression of blood supply to cord causing ischemia and oedema and hence loss of function

Diagnosis u In the history - especially in a known cancer patient. u MRI spine – urgent u Referral to Oncology - urgent

Treatment u Steroids – dexamethasone 16 mg po with PPI or H 2 antagonist – to reduce oedema Thereafter: Depends on histology u Depends on patient age performance status and if disease is controlled elsewhere u

Options u Surgery u XRT u Chemo u BSC

Surgery u Anterior laminectomy – allows better removal of tumour and reconstruction of vertebral body u Suitable for patients who are fit for surgery, have unstable spine, or radio-resistant tumour, and disease at only one level, with disease elsewhere either absent or controlled

Surgery + XRT (1) Trial 2005: surgery + radiotherapy (XRT) vs XRT alone. US, 7 centres, 101 pts. u Those receiving surgery + XRT vs XRT u – Able to walk: 84% vs 57% – Median time able to walk: 122 vs 13 days – Continent: 156 vs 17 days – Regained ability to walk: (n= 32) 62% vs 19% – Survival: 126 vs 100 days Ref: 1. Patchell 2005 Direct decompressive surgical resection in the treatment of spinal cord compression caused by metastatic cancer a randomised trial” Lancet 366(9986): 643 -8

Radiotherapy alone u Remains the majority, despite evidence above u In patients unfit for surgery; with multi-level disease; with disease elsewhere that may or may not be controlled; with some residual neurological function

Radiotherapy u Lack of randomised trials – literature review only (1) u 20 Gy in 5 # over 1 week u Started as soon as is reasonably practical u Direct field, prescribed to the depth of the cord Ref: 1. Emergency treatment of malignant extradural spinal cord compression: an evidence-based guideline DA Loblaw and NJ Laperriere Journal of Clinical Oncology, Vol 16, 1613 -1624,

Radiotherapy u May use higher dose if post op or if only site of metastasis ( 30 Gy in 10#) u If plasmacytoma, use radical dose of 40 Gy in 25#

Side effects u Exit u Skin dose: bowel: diarrhoea oesophagus: odynophagia reaction - mild

Outcomes u No immediate benefit u Some neurological improvement over following weeks; improved pain control; or halting of further deterioration u Glasgow study: 74% patients died within 3 months of diagnosis (1) 1. A Mc. Linton and C Hutchison Malignant spinal cord compression: a retrospective audit of clinical practice at a UK regional cancer centre British Journal of Cancer (2006)

Chemotherapy u Perhaps as follow up to initial treatment but rarely as first line management u e. g. in lymphoma or small cell lung cancer or teratoma

Best Supportive Care u Once neurological function lost, recovery unlikely. u If disease elsewhere is advanced, may be appropriate not to treat actively. u Steroids, physiotherapy, analgaesia, good nursing care

Multidisciplinary care u Rehabilitation u Nursing care – pressure sores; thromboembolic disease; analgaesia u Personal dignity u Lack of autonomy u End stage of illness u If discharge planned, OT, SW and PT input

Multidisciplinary care u Keeping patient and family informed u Financial assistance (DS 1500)

Prevention u Listen to patient history – early detection u If known to have bony metastases, role of bisphonates - prostate and breast cancer patients (1) u Early referral to Oncology 1: J R Ross Systematic review of role of bisphonates on skeletal morbidity in metastatic cancer BMJ 2003; 327: 469
