Official title: Optimizing Brachytherapy Application and Delivery With MRI Guidance for Gynecologic Cancer

Status Active, not recruiting

Clinical Trial Summary

The aim of this study is to develop new tools using magnetic resonance imaging (MRI) that will improve the brachytherapy procedure and treatment for participants with gynecologic cancer.

Clinical Trial Description

This research study is designed to develop new technology using MR imaging to improve the brachytherapy procedure for participants with gynecologic cancer. The brachytherapy procedure will take place in an MRI procedure room within the Advanced Multimodality Image-Guided Operating (AMIGO) suite at Brigham and Women's Hospital. The purpose of the study will be to evaluate whether the use of an MR-tracking device will improve the placement of the brachytherapy catheters. This information will also be used to develop new software for real-time brachytherapy planning by our physics team. The investigators believe that the development of an MR-tracking device will allow them to better place the brachytherapy catheters for radiation treatment and ultimately improve outcomes for patients, including better local tumor control and a lower risk of side effects. The investigators will also evaluate new MRI protocols to better define the tumor at the time of brachytherapy. The brachytherapy treatment planning and delivery will follow standard of care. In the past, brachytherapy treatment planning and delivery for gynecologic cancer was based on plain-film X-rays, which did not account for the shape of the tumor, the unique anatomy of an individual patient or the response to pelvic radiation therapy. In the last decade, advances in technology have made it possible to perform the brachytherapy procedure and to plan the delivered radiation dose based on CT or MR imaging. The use of CT or MR imaging for brachytherapy planning is increasingly common in the United States, and has been shown to result in improved tumor controls rates and a lower risk of radiation complications. The use of MRI-guidance during the brachytherapy procedure is unique and this study will contribute the advancement of this important technology. About half of the participants in this study will be selected to have the MRI-guided brachytherapy procedure with the use of an MRI-tracking device. This device will provide real-time positioning information of the individual brachytherapy catheters while they are being placed and adjusted within the tumor. The MR-tracker will also be used to develop new software that will allow our physics team to generate a near-instantaneous brachytherapy plan as individual catheters are placed during the procedure. The investigators hope that these advances in technology will have a meaningful impact on further increasing tumor control and limiting the complication risk for our participants. ;
