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.
