Purpose: To describe global quality of life (GLQL) in patients with metastatic testicular cancer (TC) treated with four different schedules of bleomycin, etoposide, and cisplatin (BEP) chemotherapy (four v three cycles given over 5 v 3 days).
Patients and methods: Quality-of-life data were prospectively collected in 666 patients with metastatic TC entered into the European Organization for Research and Treatment of Cancer (EORTC) Trial 30941/United Kingdom Medical Research Council Trial TE20, using the EORTC Quality-of-Life Questionnaire C30 and a TC module. Data were analyzed by a mixed effects model and by evaluation of clinically relevant changes at 2 years.
Results: The pattern of GLQL changes was similar in the four groups. Two years after chemotherapy, 36% of patients displayed improved GLQL as compared with baseline, whereas GLQL had deteriorated in 13%. At 3 months, patients receiving the 3-day regimen experienced increased gastrointestinal (GI) toxicity more than those receiving the 5-day regimen, with the difference reaching the level of clinical relevance (>or = 10-point change) if four cycles were given. The 3-day schedule increased the 2-year risk of tinnitus, with clinical relevance demonstrated after four cycles. Long-term peripheral neuropathy and Raynaud-like phenomena were not associated with the number of cycles or days per cycle. At 2 years, Raynaud-like phenomena, tinnitus, or reduced hearing were reported by 21% to 26% of the patients.
Conclusion: Because of the excess of acute GI toxicity and the increased risk of tinnitus after the 3-day regimen, we recommend the 5-day regimen if four cycles of BEP are planned. If only three cycles are to be given, then the 3-day regimen is acceptable, even given the increased risk of nausea/vomiting at 3 months.
