Filter by:This research study will enroll people who have cancer in their abdomen or pelvis that was treated previously with radiation therapy. The purpose of this research study is to test the safety and possible harms of treating tumors in these regions with another round of radiation therapy, called reirradiation or "reRT." The researchers want to find out what effects (good and bad) reRT has in people with cancer in the abdomen and pelvis.
The primary objective of radiation therapy is to deliver a therapeutic dose of radiation precisely to the target while minimizing exposure to healthy surrounding tissues. Image-guided radiation therapy (IGRT) involves acquiring cone beam computed tomography (CBCT) scans just before or during treatment sessions. By comparing the CBCT images with the reference images from the treatment planning process, clinicians can make necessary adjustments to ensure precise targeting and account for any changes that may have occurred since the initial planning. Conventional CBCT technology is, however, limited by several factors including long acquisition times that result in motion artifacts in the image, smaller fields of view that limit the volume of anatomy that can be imaged, poor image quality that limits soft tissue visibility, and artifacts created by dense metal implants. This study will evaluate a novel CBCT imaging solution ("HyperSight") that has the potential to address the challenges of conventional CBCT.
In this study, investigators utilize a Artificial Intelligence (AI) supportive system to predict radiation proctitis for patients with pelvic cancers underwent radiotherapy. By the system, whether the participants achieve the radiation proctitis will be identified based on the radiomics features extracted from the post radiotherapy Magnetic Resonance Imaging (MRI) . The predictive power to discriminate the radiation proctitis individuals from non-radiation proctitis patients, will be validated in this multicenter, prospective clinical study.
