Abstract

Thirty-four patients with renal cell carcinoma and brain metastases were reviewed to define important prognostic factors and treatment results. The following covariates were analyzed to determine their influence on survival: disease-free interval, serum calcium, number of central nervous system (CNS) metastases, weight loss, performance score, age, radiation therapy, surgery, and surgery plus radiation. The mean survival for all patients was 7.0 months (range, seven days to 32 months). The patients with a good performance score of 0-2 survived significantly longer (mean survival, 10.2 months) than those with a poor performance score of 3-4 (mean survival, 2.8 months; p = 0.0019). Surgery was associated with significantly improved survival (mean survival, 13.8 months versus mean survival, 4.2 months; p = 0.014). However, all the surgical patients were from the good performance score group, suggesting patient selection. Radiation was associated with an improved mean survival of 8.6 months versus 3.2 months. Performance score is a significant prognostic factor. Furthermore, the data support treatment with radiation therapy for patients with multiple CNS metastases and surgery followed by postoperative radiation therapy for patients with single CNS metastases.
