Metastatic Spinal Cord Compression (MSCC), an oncologic emergency, is a frequent complication of many neoplastic diseases in an advanced stage. Our experience is reported, which was obtained with a series of 61 patients following a diagnostic-therapeutic protocol aimed at early diagnosing MSCC and at assigning the major role in therapy to radiotherapy (RT) alone. Fifty-seven patients with an average follow-up of 13 months (range 4-26) were evaluable. Diagnosis was always made by means of myelography and/or myelography plus CT. In 50 cases the treatment consisted in RT alone and the remaining 7 patients had surgery before RT because of diagnostic doubts; in 1 case the patient was operated on because stabilization was necessary. A dose of 30 Gy was delivered, over 2 weeks, (TDF = 62) to those tumors which were considered as radiation-responsive and having a better prognosis (myeloma, lymphoma), whereas all the other histologies were given a split-course regimen (5 Gy x 3 days, stop x 4 days, +/- 3 Gy x 5 days; TDF = 68). All patients received medium or high doses of steroid depending on the degree of neurologic involvement. Patients with chemo/hormone-responsive primary tumors also received chemotherapy and/or hormone therapy. The clinical parameters considered in evaluating the response to treatment were backache, motor performance, and sphincter function. Respectively 86%, 47% and 44% of patients responded. Early diagnosis was the most important prognostic factor, whereas histology of the primary tumor was important in cases with severe neurologic damage only. The results obtained are similar to those reported in literature and confirm the value of the diagnostic-therapeutic approach used, which suggests continuing this trial.
