Radiation therapy options compared for newly diagnosed gynecologic cancers
Official title: A Phase II, Randomized, Open-Label, Single-Center Study Comparing Intensity Modulated Proton Therapy Versus Volume Modulated Arc Therapy in Patients Receiving Pelvic Nodal Irradiation for Newly Diagnosed Gynecologic Primaries
Run by University of Maryland, Baltimore · NCT07415681 · Data updated 2026-11-12
This study tests whether proton therapy works as well as conventional photon therapy for endometrial and cervical cancers.

Is this trial a fit for you?
✓Likely a good fit
Adults with newly diagnosed endometrial or cervical cancer planned for sequential or concurrent chemoradiation (with brachytherapy boost for cervical cancer) and meeting eligibility criteria including insurance coverage for IMPT.
✕Probably not a fit
Patients with metastatic disease beyond para-aortic nodes, large residual tumors after surgery, certain advanced cervical cancer stages, or those unable to receive IMPT may not benefit.

What this trial studies
This is a phase 2 randomized trial comparing two standard radiation techniques—volume modulated arc therapy with photons (VMAT) and intensity-modulated proton therapy (IMPT)—in newly diagnosed gynecologic cancers. Participants are randomly assigned to receive one of the two treatments as part of their planned chemoradiation or definitive chemoradiation with a brachytherapy boost. The study aims to compare side effects and tolerability between the two approaches while maintaining standard-of-care treatment. Eligible patients are adults with newly diagnosed disease who meet specific surgical and treatment criteria and have appropriate insurance for IMPT. The trial is conducted at multiple Maryland sites with lead involvement from the University of Maryland, Baltimore.
Why it matters
Potential benefit: If successful, patients may experience similar cancer control with different or reduced treatment-related side effects.
How similar studies have gone: Previous studies have explored proton therapy in gynecologic cancers, but randomized comparisons to photon therapy in this setting are limited.
