Hyaluronic Acid-based Gel Spacers in Gynecologic Malignancies

Study Summary

This pilot feasibility study evaluates the use of a hyaluronic acid-based spacing gel (Barrigel) in participants with cervical cancer undergoing chemoradiotherapy (chemoRT), including brachytherapy, as part of standard care. The primary goal is to assess feasibility. Other goals include determining whether gel placement can reduce radiation dose to nearby healthy organs (organs at risk, OAR) and improve delivery of the prescribed radiation dose to the tumor. In cervical cancer, the radiation dose to the tumor is often limited by the risk of exposing nearby sensitive organs, such as the rectum, bladder, and other pelvic structures. Vaginal packing techniques and specialized devices are used to protect these organs and ensure effective treatment. Gel spacers are inserted before radiation therapy to create space between the rectum and the cervix, reducing radiation exposure to healthy tissue. Already widely used in prostate cancer treatment in the U.S., gel spacers may also help improve tumor control and reduce treatment-related toxicity in cervical cancer.

Primary Outcome

The NCI Common Terminology Criteria for Adverse Events (NCI-CTCAE) is a descriptive terminology that can be utilized for Adverse Event (AE) reporting. A grading (severity) scale is provided for each AE term. Grade 1 Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated. Grade 2 Moderate; minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental Activities of Daily Living (ADL). Grade 3 Severe or medically signi
