Abstract

Object: This prospective randomized clinical study will address the efficacy of radiation (RT)-alone and combined with pre-RT chemotherapy (CTX) treatments and propose the novel standard treatment strategy for intracranial primary pure germinoma. Materials and methods: Between 2005 and 2008, there were 54 patients diagnosed with intracranial primary pure germinomas in a single institute. Twenty-eight patients were enrolled. The mean age of the patients was 16.2 years (range 6-31 years). There were 19 men and 9 women (men/women ratio = 2.1:1). There were 21 patients with solitary tumors and 7 with multiple tumors. These patients were randomized as RT-only treatment group (11 solitary and 3 multiple tumors) and combined (10 solitary and 4 multiple tumors, neo-adjuvant CTX followed by response-adapted RT) treatment group. The follow-up period for RT only group has a median of 58 months (mean 58.2 months, range 41-82 months), and for combine therapy group, the median was 68.5 months (mean 67.8 months, range 41-88 months). All 14 patients in the RT-only group showed complete response (CR) and no recurrence. Eleven patients in the combined group had CR and three patients had partial response after neo-adjuvant CTX. All patients responded to RT as CR without recurrence. At the time of analysis, all 28 patients were alive without evidence of disease. Conclusion: Neo-adjuvant CTX for localized germinomas seems to be unnecessary as a method to reduce radiation dose in our RT protocol. However, the effective control of multifocal or disseminated germinoma can be achieved by neo-adjuvant CTX followed by response-adapted reduced dose RT.
