Résumé

JCO GETUG-13 established that switching patients with poor-prognosis nonseminomatous germ-cell tumors with an unfavorable marker decline to intensified chemotherapy resulted in improved outcomes. Here, we report the GETUG-13 long-term efficacy and toxicity. Two hundred and sixty-three patients with International Germ Cell Cancer Consensus Group poor prognosis received one cycle of bleomycin, etoposide, and cisplatin (BEP): 51 with a favorable tumor marker decline continued with three cycles of BEP (Fav-BEP) and 203 with an unfavorable decline were randomly treated with three BEP (Unfav-BEP) cycles or a dose-dense regimen (Unfav-dose-dense; two cycles of paclitaxel-BEP-oxaliplatin + two cycles of cisplatin, ifosfamide, and bleomycin). The median follow-up was 7.1 years (range, 0.3-13.3). Five-year progression-free survival (PFS) rates were 58.9% in the Unfav-dose-dense arm and 46.7% in the Unfav-BEP arm (hazard ratio [HR], 0.65 [95% CI, 0.44 to 0.97]; = .036). Five-year overall survival rates were 70.9% and 61.3% (HR, 0.74 [95% CI, 0.46 to 1.20]; = .22). Side effects evolved favorably, with only three patients in the Unfav-dose-dense arm reporting grade 3 motor neurotoxicity at 1 year and no reported toxicity over grade 1 after year 2. Salvage high-dose chemotherapy plus a stem-cell transplant was used in 8% in the Unfav-dose-dense arm and 17% in the Unfav-BEP arm ( = .035). Long-term outcomes suggest a sustained benefit of intensified chemotherapy in terms of PFS and numerically better survival, with a minimal toxicity and reduced use of salvage high-dose chemotherapy plus stem-cell transplant.
