Hypofractionated Chemoradiotherapy for Cervical Cancer

Cervical cancer remains a major health problem in Thailand and other lowand middle-income countries. The current standard treatment for locally advanced cervical cancer consists of conventionally fractionated external beam radiotherapy delivered over 5-7 weeks with concurrent chemotherapy, followed by brachytherapy. This prolonged treatment schedule requires frequent hospital visits and may limit access to care. Hypofractionated radiotherapy delivers a higher dose of radiation per treatment session while maintaining a comparable total radiation dose, thereby reducing the overall treatment duration. Preliminary studies suggest that hypofractionated chemoradiotherapy using modern radiotherapy techniques may provide similar disease control and acceptable toxicity compared with conventional treatment, while improving treatment convenience and reducing healthcare burden. This multicenter phase III randomized controlled trial aims to compare hypofractionated whole pelvic concurrent chemoradiotherapy with conventional chemoradiotherapy in patients with early-stage node-positive and locally advanced cervical cancer. The study will evaluate nodal control and overall survival, as well as tumor response, treatment-related toxicities, quality of life, and cost-effectiveness.
