What this Trial Is About
This research aims to collect data from 30 male patients aged 16 years and older who have stage II seminoma, a type of testicular cancer. It evaluates different treatment strategies, including standard of care and de-escalated treatments, to understand their impact on cancer and quality of life. The study is a feasibility observational cohort designed to help plan larger trials by assessing recruitment willingness and treatment effects over about three years. Patients are assigned to one of two treatment groups based on their eligibility and institutional practices. One group undergoes retroperitoneal lymph node dissection (rRPLND) surgery followed by further treatment or monitoring depending on surgical findings. The other group receives Carboplatin AUC10 chemotherapy. Those not eligible for or declining these treatments may receive other chemotherapy regimens or radiotherapy. All treatments follow shared decision-making between patients and clinicians. Participants are monitored for up to two years after treatment ends or until withdrawal or death. The study includes regular evaluations of quality of life through questionnaires, cancer progression, survival rates, and treatment safety. Data collected will help inform future larger studies and patient care strategies. After the study, patients continue their care according to institutional protocols.
