RCT: Radiation therapy alone superior to chemoradiation in low-grade localized endometrial cancer recurrences

This randomized clinical trial assessed the effectiveness of radiation therapy alone versus concurrent chemoradiation in treating localized recurrences of endometrial cancer. Conducted from February 2008 to August 2020, the study involved 165 patients who were randomized to receive either radiation therapy alone or chemoradiation with weekly cisplatin. Findings indicate that radiation therapy alone resulted in longer progression-free survival (PFS) compared to chemoradiation, with a median PFS not reached for radiation alone versus 73 months for chemoradiation. Additionally, radiation therapy demonstrated lower rates of acute toxicity. The study concluded that for patients with low-grade and primarily vaginal recurrences, radiation therapy alone is the preferable treatment option, offering excellent outcomes without the added toxicity of chemotherapy.
