Higher radiation dose to the tumor to avoid surgery in rectal cancer
Aims to see if giving a higher dose of radiation to the tumor can help people with non-locally advanced rectal cancer keep their rectum without needing surgery.
-
Hypofractionated radiotherapy after prosthetic breast reconstruction
This study tests whether a shorter, higher-dose radiotherapy course (HFRT) works as safely and effectively as the standard longer course (CFRT) for patients who had a mastectomy with implant reconstruction.
-
Comparing surgery with and without postoperative radiotherapy for esophageal cancer
This study is testing if adding radiation treatment after surgery can help people with Stage II or III esophageal cancer live longer and have fewer cancer recurrences.
-
Short-course radiotherapy followed by chemotherapy for rectal cancer
This study is testing whether a short course of radiation followed by chemotherapy can help people with locally advanced rectal cancer respond better to treatment before surgery.
