title: [Chemotherapy of disseminated germ cell tumors].
abstract: Current modes and issues of chemotherapy for the patients with disseminated germ cell tumors (GCTs) are described. A review of the literature of prospective randomized trials designed to compare the efficacy and toxicities between induction chemotherapy regimens for patients with either good- or poor-risk disseminated GCTs showed that three cycles of bleomycin, etoposide, and cisplatin (BEP) or four cycles of etoposide and cisplatin (EP) for good-risk GCTs, and four cycles of BEP for poor-risk GCTs, are the most effective regimens even now. A prognostic factor-based staging system can distinguish patients with either good- or poor-risk GCTs, and help make risk-based decisions about therapeutic modes. However, there is a variety of criteria that make intertrial comparison difficult. An internationally accepted prognostic classification of disseminated GCTs reported recently by the International Germ Cell Cancer Collaborative Group will resolve these problems. High-dose chemotherapy (HDCT) with autologous stem cell rescue can cure a relatively small but significant percentage of heavily pretreated patients who are deemed incurable with any other therapeutic strategy. Moreover, HDCT in first-line therapy for patients with poor-risk GCTs is now expected to improve treatment outcome obtained by BEP. Because HDCT has not totally overcome cisplatin-resistance, further investigation should be required.
