Sequential Salvage Chemotherapy For Cddp-Refractory Advanced Testicular Cancer: Japanese High-Volume Center Experience

e15526 Background: Chemotherapy- refractory or resistant GCTs, so called ‘difficult-to-treat’ GCTs would remain continuously disease-free with salvage chemotherapy or surgery. The optimal salvage chemotherapy remains unclear. The aim of this study was to assess the efficacy of ‘sequential’ chemotherapy for advanced testicular cancer. Methods: Salvage chemotherapy was required in 129 patients out of 233 advanced GCTs treated at Kyoto Prefectural University of Medicine from June, 1998 to December, 2011. Clinical outcomes were retrospectively assessed. Results: Median age was 31 year-old (range:17-65y.o.). Non-seminoma was in 111 cases (86.0%). IGCCC showed good in 37 cases (28.9%), intermediate 33 (25.6%), poor 47 (36.4%), and unknown 12 (9.1%). As the 2nd line therapy, VIP/VeIP and TIP/N therapy were done in 43 (33.3%) and 49 cases (38.0%), respectively. With regard to the patients requiring 3rd line or more chemotherapy, 95, 67, 40, 26 cases had 3rd, 4th, 5th and 6th line or more chemotherapy, respectivel...
