Radiation injury

This trial is testing whether giving a special type of radiation (ultra-hypofractionated) along with immunotherapy before surgery is safe and feasible for people with retroperitoneal sarcoma. The study will enroll 28 participants. The main goal is to see how many patients have co…

This early-phase trial tests whether umbilical cord blood cells can safely help people with chronic radiation enteritis, a painful gut condition caused by cancer radiation therapy. Ten adults who have had pelvic or abdominal radiation will receive three weekly infusions of these …

This study looks at whether advanced heart tests and blood markers can find early signs of heart damage in children who had chemotherapy or chest radiation for cancer. About 100 survivors aged 2 to 25 will undergo special echocardiograms, exercise tests, and wear activity monitor…

This study tests whether removing a thin layer of tissue (pseudomembrane) from the back of the nose using a scope can prevent radiation-induced tissue death in patients with recurrent nasopharyngeal cancer who have had repeat radiation. About 40 adults in China will undergo the p…

This study tests whether a modified herbal mouthwash can prevent painful mouth sores caused by radiation therapy in people with head and neck cancer. About 156 participants will use either the herbal mouthwash or a placebo during their radiation treatment. The goal is to see if t…

This study tests whether a steroid nasal spray can prevent fluid buildup in the middle ear, a common side effect of radiation therapy for nasopharyngeal cancer. About 168 adults who are about to start radiation will use either the spray or a placebo for 12 months. The goal is to …

The PRISM trial compares two radiation approaches after breast-conserving surgery for early-stage breast cancer. One approach treats only the area around the original tumor, while the other treats the whole breast. Both use the same short schedule of five radiation treatments. Re…

This trial tests whether custom 3D-printed intraoral stents can protect the mouth from radiation damage in children with medulloblastoma, a type of brain cancer. During radiotherapy, the stent is worn inside the mouth to physically move healthy tissue away from the radiation beam…

This study will follow 120 people with chronic pain, nerve damage from chemotherapy, radiation side effects, or slow-healing wounds who are referred for ozone therapy. Researchers will track changes in quality of life, pain, and other symptoms over several months. The goal is to …

This study looks back at the medical records of 60 adults with head and neck cancer who received radiation therapy, with or without chemotherapy, and used a topical mouth rinse made from olive oil, betaine, and xylitol. The goal is to see how often severe mouth sores (oral mucosi…

This study will collect data from 500 Danish cancer patients who need repeat radiation therapy (reirradiation). Researchers will track side effects, tumor control, and survival to build a database that can guide safer treatment in the future. The goal is to help doctors decide wh…

This study aims to identify biological markers that could predict radiation-induced intestinal injury in people receiving abdominal radiotherapy. Researchers will observe 220 adult patients who are about to start high-dose radiation. By analyzing samples and outcomes, they hope t…

This study tests a new questionnaire called PET (Patient Experience in Telehealth) to see if it accurately measures how patients feel about telemedicine visits. Researchers will ask 200 adults who had a telemedicine appointment at an Italian hospital to fill out the survey. The g…
