Epidural cord compression in association with genitourinary neoplasms.

The epidural compression secondary to genitourinary malignancies is relatively uncommon. Of 2118 patients who were diagnosed as having a genitourinary malignancy at the Columbia-Presbyterian Medical Center from 1970-1979, 21 are known to have developed an epidural cord compression by June 30, 1985 (16 from prostate, 1 from urinary bladder, and 4 from renal origin). The following items were reviewed in these 21 patients: age of the patient at diagnosis of the primary tumor; primary site of the genitourinary primary; time in months from the date of diagnosis of the genitourinary primary to the data of diagnosis of the spinal cord compression; methods of diagnosis; presenting symptoms and signs; treatment methods; and survival following the date of diagnosis of the compression. The distribution of location of the epidural metastasis in the current series is as follows: cervical-thoracic, 7%; thoracic, 73%; and lumbosacral, 20%. Skip metastases to the epidural space was the initial sign of malignancy in six patients (31.5%). Five patients (26%) with epidural cord compression survived at least 24 months following the date of diagnosis of their compression. Only two patients in this series with paraplegia (secondary to their compression) had improvement in ambulation following treatment of their compression: of these two patients, one had a prostate primary and the other a renal primary. The indications and techniques for surgery and radiotherapy are briefly described and early diagnosis and treatment are stressed.
