What this trial studies

This clinical trial investigates the use of Stereotactic Ablative Radiation (SABR) in patients with post-operative endometrial cancer. Participants will receive a total dose of 30 Gy delivered in 5 fractions once weekly to the pelvis. The study aims to evaluate the effectiveness of this targeted radiation therapy in improving outcomes for patients who meet specific eligibility criteria related to their cancer stage and histology. The trial focuses on patients who are candidates for adjuvant pelvic radiation therapy.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with histologically confirmed endometrial adenocarcinoma who meet specific criteria for adjuvant pelvic radiation.

Not a fit: Patients with prior pelvic radiotherapy, Type II endometrial cancer histology, or contraindications to pelvic radiotherapy will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance treatment outcomes and reduce recurrence rates in patients with endometrial cancer.

How similar studies have performed: While there is ongoing research in the field of stereotactic radiation for various cancers, this specific approach in endometrial cancer is relatively novel and has not been extensively tested.
