Neurosurgical aspects of urologic metastases

Metastases in the central nervous system (C.N.S.) from urological tumors can be spinal or craniocerebral. The experience of 30 patients with spinal and craniocerebral metastases from urological tumors admitted to Neurosurgical Clinic of the University of Milan, is reported. They were 7.5% of the all number of metastases admitted at the Neurosurgical Department, during the same period. The brain metastases constitute 10% of brain metastases diagnosed in this period. Only patients with solitary (to CT scan and NMR) metastasis, and with a general prognosis that allow to an adequate and useful period of survival, are submitted to surgical treatment. 23 patients (76.6%) are surgical treated. The mean survival from the discovery of the C.N.S. metastases was 9 months (9.4 months among surgically treated patients and 7.8 months among those were not operated). Surgical mortality was 13%. Out of patients with survival until 5 months, patients submitted to surgical treatment showed a better quality of life. Our results allow us to affirm that in selected patients surgical removal of solitary metastases, could improve the quality of survival, but is not able to prolong substantially the period of survival.
