Comparison of Conventional and Hypofractionated IMRT in High-Risk Cervical Cancer Post-Radical Hysterectomy

Recruiting now · Phase 3

Conditions studied: Uterine Cervical Neoplasms

In brief

Radical hysterectomy and radiation therapy are standard treatments for cervical cancer. However, there are no reported studies on the frequency of side effects and treatment outcomes when hypofractionated radiation therapy and intensity modulated radiation therapy(IMRT) are used during radiation therapy. Hypofractionated radiation therapy increases the daily dose and reduces the number of treatment sessions, which may increase the risk of side effects, but its safety has been confirmed in some cases of early cervical cancer and endometrial cancer. Additionally, applying IMRT, a technique designed to protect normal tissue, during concurrent chemoradiotherapy has shown positive results in reducing the incidence of acute side effects. Investigators previously demonstrated that combining hypofractionated IMRT with chemotherapy for high-risk postoperative cervical cancer patients resulted in high survival rates and low toxicity in a phase 2 exploratory study. Base on this result, this study aimed to compare the efficacy and safety of conventional fractionated radiation therapy and hypofractionated radiation therapy.
