Proton therapy for treating gynecologic cancer after surgery

Adjuvant Proton Whole Pelvis Radiation Therapy for Treatment of Post-Surgical Gynecologic Cancers

Phase 2 Interventional Abramson Cancer Center at Penn Medicine · NCT05758688

This study is testing a new type of radiation therapy after surgery to see if it helps women with cervical and endometrial cancer while causing fewer side effects.

What this trial studies

This Phase II, single-arm study evaluates the use of Whole Pelvis Pencil Beam Scanning Proton Radiation (PBS PRT) as a post-surgical treatment for patients with gynecologic cancers, specifically cervical and endometrial cancer. The study aims to assess the rate of acute gastrointestinal toxicity associated with this radiation therapy in the adjuvant setting. Conducted at multiple Penn proton centers in the Philadelphia, Lancaster, and South New Jersey areas, patients will receive radiation doses of either 45 or 50.4 Gy in daily fractions. The goal is to improve treatment outcomes while minimizing side effects.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with histologically confirmed cervical or endometrial cancer who require adjuvant whole pelvic radiation therapy.

Not a fit: Patients with prior pelvic radiation, metastatic disease outside the pelvis, or active inflammatory bowel disease may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could reduce gastrointestinal toxicity while effectively managing gynecologic cancers post-surgery.

How similar studies have performed: Other studies using proton therapy for cancer treatment have shown promising results, indicating potential for success in this approach.
