Spinal cord compression in metastatic prostate cancer.
BACKGROUND
Spinal cord compression (SCC) in metastatic prostate cancer is not rare occurring in 1 to 12% of patients. We have analysed patients treated for this condition in our institution assessing outcome and prognostic factors.


METHODS
Retrospective analysis of the notes of 24 patients hospitalised with SCC due to metastatic prostate cancer from 1987 to 2001.


RESULTS
At presentation 3 patients were ambulant with mild neurological deficit, 12 patients were paraparetic and 9 patients were paraplegic. Diagnosis was established by emergency myelogram, CT-scan or MRI of the spine. 8 patients had received no hormone treatment prior to diagnosis of SCC. 19 patients presented dorsal or lumbar pain requiring opioid treatment on average 60 days before onset of neurological symptoms (range 10-840). All patients underwent steroid treatment; the 8 patients without prior hormone therapy were treated with bilateral orchidectomy, 1 out of these 8 patients had castration without other treatments; 12 patients underwent radiotherapy alone and 9 radiotherapy and laminectomy; 2 patients were in terminal conditions and receive only steroid treatment. Overall 15/24 patients were ambulant after treatment. 8 out of 9 patients treated by laminectomy and radiotherapy were ambulant after treatment versus 7 out of 12 patients treated by radiotherapy alone.17 patients died during follow-up with a median survival of 4 months (2 weeks to 49 months). 7 patients were alive at the last control with a mean follow-up of 10 months (range 4-40).


CONCLUSIONS
Outlook in patients with spinal cord compression from metastatic prostate cancer is poor. Efforts must be concentrated on prevention of spinal cord compression. Patients with hormone resistant prostate cancer who develop persistent back pain should undergo imaging studies (bone scan, spine CT-scan or MNR) and prophylactic local radiotherapy to the spine if bony metastases are identified.
