Researchers are conducting an observational study called SOGUG-PRINCIS to collect and analyze data on the effectiveness of drugs recently approved for treating genitourinary tumors under routine clinical practice in Spain. This national, multicenter study includes both retrospective patient data and prospective follow-up, aiming to validate real-world outcomes compared to those reported in phase III clinical trials. The study covers cancers originating in the kidney, ureter, bladder, prostate, testicle, urethra, penis, and seminal vesicles. The study observes patients treated with drugs such as darolutamide combined with androgen deprivation therapy and docetaxel, adjuvant nivolumab after surgical removal of urothelial carcinoma, and enfortumab vedotin. All treatments follow their approved dosing and administration guidelines in standard clinical practice. New subprojects may be added as new drugs gain funding approval by the Spanish National Health System, with each subproject focusing on specific primary endpoints. Participants' involvement includes treatment decisions made independently from the study, with data collected afterward to assess outcomes. Researchers will track progression-free survival at 18 months, relapse-free survival at 24 months, and overall survival at 12 months after treatment initiation. The study also serves as a registry for genitourinary cancer treatments funded nationally, supporting long-term evaluation of drug effectiveness in real-world settings.
