Phase II Study of Personalized Adjuvant Therapy for Early-Stage POLE-Mutated and p53-Wildtype Endometrial Cancer RAINBO BLUE & TAPER

What this Trial Is About

Researchers are evaluating a new approach to adjuvant treatment for patients with early-stage endometrial cancer characterized by POLE mutations or p53 wildtypeno specific molecular profile. This Phase II study compares this tailored treatment approach to the usual care, which typically involves surgery followed by additional therapy decisions based on pathology results. The study includes two sub-studies focusing on these molecular types of endometrial cancer. Participants may receive one of several interventions including observation alone, observation combined with adjuvant radiotherapy, or observation combined with vaginal brachytherapy. Radiotherapy uses specific photon energies and imaging for treatment planning, while vaginal brachytherapy is delivered with a vaginal cylinder or ovoids. Treatment starts within 10 weeks after surgery, and patients are assigned to groups based on their tumor molecular status. During the study, participants are monitored for recurrence rates in the pelvis, vagina, para-aortic area, and distant sites over 3 years, as well as recurrence-free survival, cancer-specific survival, and overall survival over 9 years. Patient-reported outcomes on fear of recurrence are also collected. Careful follow-up and data collection continue throughout the study, which concludes in 2029, ensuring thorough evaluation of this tailored treatment approach.
