Treatment of brain metastases from bladder cancer.

The records of 28 patients with transitional cell cancer who had brain metastases were retrospectively reviewed. Data from 19 patients were considered suitable for analysis and were included in this study. One patient was treated with surgery alone, 10 with radiation alone and 7 with radiation and surgery, while 1 received no treatment. Mean and median survival times, respectively, were 57 and 42 months from the initial diagnosis, and 11 and 4 months from diagnosis of central nervous system metastases. Patients treated with surgery and radiation demonstrated a mean survival time of 19 months compared to 6 months for patients treated with radiation alone (p = 0.03). There were 2 long-term survivors in the combined modality group at 50 and at 12 months. Enthusiasm for combined modality treatment should be tempered by the fact that selection bias favored the combined modality group; 13 patients with single lesions demonstrated a mean survival of 14 months compared to 3 months for 6 patients with multiple lesions (p = 0.009) and only patients with solitary lesions underwent surgical resection. Brain metastases have an ominous prognosis in patients with bladder cancer primaries. Considering the sum of the retrospective and prospective reports, we recommend that patients with solitary brain lesions and good performance status be aggressively managed with surgical resection and postoperative radiation therapy.
