Summary
Brief summary (as posted)
Phase II, multicenter, prospective, randomized, non-comparative, de-escalation study. Patients with stage IIa/IIb \< 3 cm seminoma histologically proved after orchiectomy will be included in the study and will receive 1 cycle of Etoposide Cisplatine (EP) chemotherapy. Patients with negative week-3 PET-scan after the EP cycle, will be randomized (1:1 ratio, stratification according to the disease stage (stage IIa versus IIb seminoma)) to receive either radiotherapy (RT) boost on lymph nodes or 1 cycle of carboplatin AUC7 chemotherapy. Patients with positive week-3 PET-scan will received 3 additional cycles of EP chemotherapy. In parallel, eligible patients scheduled to receive standard lombo-aortic RT will be registered in an observational cohort.

Uncontrolled or severe hepatic pathology. 6. Patient deprived of liberty or requiring tutorship or curatorship. 7. Psychological, physical, sociological, or geographical conditions that would limit compliance with study protocol requirements (at the investigator's discretion). 8.
