Postoperative Hypofractionated Whole Pelvic Radiotherapy in Cervical and Endometrial Cancer (PostOP HYPOCxE)
PostOPerative HYPOfractionated Whole Pelvic Radiotherapy in Cervical (Cx) and Endometrial Cancer (PostOP HYPOCxE Trial) : A Phase II Non-inferiority Randomized Controlled Trial
This study aims to evaluate a shorter course of postoperative pelvic radiotherapy in patients with cervical and endometrial cancer. The standard radiotherapy schedule usually requires many treatment sessions over several weeks, which can be burdensome for patients and may affect their ability to complete treatment.
This study will compare a shorter radiotherapy schedule (hypofractionated radiotherapy) with the standard schedule. Both treatments deliver a similar total radiation dose, but the shorter schedule reduces the number of hospital visits and overall treatment time.
Participants will be randomly assigned to receive either the shorter or standard radiotherapy after surgery. The study will evaluate side effects, treatment effectiveness, and quality of life. The goal is to determine whether the shorter treatment is as safe and effective as the standard approach.

Подробное описание
Cervical cancer remains a major health problem, particularly in low- and middle-income countries. Standard postoperative pelvic radiotherapy requires multiple treatment sessions over several weeks, which may limit patient access, increase treatment burden, and prolong overall treatment time. Prolonged treatment duration has been associated with reduced tumor control, and frequent hospital visits may also increase risks for patients, especially during infectious disease outbreaks.
Hypofractionated radiotherapy delivers a higher dose per fraction while maintaining a similar total radiation dose, allowing for a shorter overall treatment course. This approach may improve treatment convenience, reduce healthcare resource utilization, and potentially enhance treatment outcomes without increasing toxicity. However, there is currently limited high-level evidence supporting its use in the postoperative setting for cervical and endometrial cancer.
This study is a phase II randomized controlled trial designed to evaluate the safety and efficacy of postoperative hypofractionated whole pelvic radiotherapy compared with conventional radiotherapy in patients with cervical and endometrial cancer. Participants will be randomly assigned to receive either hypofractionated or standard radiotherapy following surgery.
The study will assess treatment-related toxicity, tumor response, survival outcomes, and quality of life. The results of this study may help establish whether a shorter radiotherapy schedule can be safely implemented as an alternative to standard treatment.
