The EORTC Genito Urinary Cancers Group (GUCG) concentrates on clinical research for prostate cancer. It also takes an interest in rarer diseases and biomarker-driven research.

Main Achievements

  • Effectively recruited participants for the TIGER study, the single most relevant ongoing study in testicular cancer. Without EORTC efforts, recruitment would be insufficient. The randomised trial targets relapsed germ cell cancer comparing standard TIP chemotherapy to high dose chemotherapy in collaboration with ALLIANCE.
  • Achieved 75% recruitment in the PEACE1 phase III trial on the combination of Radium223 plus enzalutamide. Study to assess if the combination improves radiological progression-free survival compared to enzalutamide single agent in asymptomatic or mildly symptomatic castration resistant prostate cancer patients metastatic to bone.
  • Published a practice-changing recommendation to mandate the use of bone protecting agents when administering the combination studied in the PEACE trial. This should help to decrease the fracture rate for patients.

EORTC’s work in Genito-Urinary cancers has led to major standard of care improvements which have been incorporated into the European Association of Urology’s treatment guidelines.

One study established the superiority of Bacillus Calmette-Guerin over chemotherapy in the treatment of non-muscle invasive bladder cancer.

Another study demonstrated that early androgen deprivation in prostate cancer significantly increased overall survival, and that 30% of patients do not need any treatment.
