Brain metastases from testicular germ cell tumors: a retrospective analysis.

OBJECTIVES: To review our series of testicular germ cell tumors with brain metastases and to establish an optimal treatment strategy for them. METHODS: Twenty-seven cases of testicular germ cell tumors from three institutions were retrospectively reviewed. RESULTS: Twenty-six were non-seminomatous tumors and only one was a seminoma. Based on the International Germ Cell Consensus Classification, two cases were classified as good prognosis, seven as intermediate prognosis and 18 as poor prognosis. Chemotherapy was carried out in all patients. Additionally, whole-brain radiotherapy was performed in 10 cases, stereotactic radiosurgery in six, whole-brain radiotherapy combined with stereotactic radiosurgery in three and complete surgical resection in five. Three patients received chemotherapy only. Cancer-specific 5- and 10-year survival rates were both 35.9%. The prognosis of those with brain metastases at the time of diagnosis tended to be better than those developing brain metastases during treatment. Those with a single brain metastasis showed significantly better survival than those with multiple brain metastases. No other significant prognostic factor was found at multivariate analysis. CONCLUSION: Testicular germ cell tumors with brain metastases can be managed with the combination of whole-brain radiotherapy, stereotactic radiotherapy, and/or surgical resection in combination with chemotherapy.[1]
