Purpose
The purpose of the study was to assess the efficacy of TIP as salvage chemotherapy for germ cell tumor (GCT) patients with relapsed disease or cisplatin (CDDP)-refractory disease and consolidation chemotherapy for patients who responded unfavorably to first-line chemotherapy.
Methods
Forty-three patients with advanced GCT were treated with TIP. Eleven with relapsed disease and five with CDDP-refractory disease received TIP as salvage chemotherapy. The remaining 27 received TIP as consolidation chemotherapy following initial induction chemotherapy. All patients received prophylactic granulocyte colony-stimulating factor.
Results
In total, 116 cycles of TIP were administered with a median of three cycles (range 1–4 cycles) per patient. Before TIP, 33 patients showed elevated tumor marker and 23 patients (70 %) achieved marker normalization with the chemotherapy. One of six (17 %) patients with refractory disease and 5 of 10 (50 %) patients with relapsed disease achieved durable complete response (CR) after TIP with or without surgery. Eighteen of 27 (67 %) patients receiving TIP as consolidation chemotherapy achieved durable CR. Five additional patients were given further chemotherapy and achieved durable CR. Grade 4 leukocytopenia and thrombocytopenia were observed in 91 and 42 % of patients, respectively; all were managed with routine supportive care. Grade 2 and grade 3 sensory neuropathy was observed in 37 and 2 % of patients, respectively.
Conclusions
The TIP was effective for relapsed patients with favorable risk features and selected CDDP-refractory GCT patients. Results of TIP as consolidation for patients with unfavorable response to the initial chemotherapy were also encouraging. The toxicities were mainly myelosuppression and sensory neuropathy.
