This clinical trial is focused on studying treatments for locally advanced rectal cancer in older patients. The trial compares two treatment approaches: short-course radiotherapy (SCRT) followed by surgery, with or without additional chemotherapy, and total neoadjuvant therapy (TNT), which involves a combination of treatments given before surgery. The main goal is to determine which approach offers a better balance between effectiveness and safety for older patients.
Participants in the study will receive various medications as part of their treatment. These include Capecitabine, Oxaliplatin, and Fluorouracil, which are commonly used in cancer treatment. Additionally, supportive medications such as Ondansetron, Dexamethasone, Folinic Acid, and Metoclopramide may be administered to help manage side effects and improve the overall treatment experience. Some patients may receive a placebo as part of the study design.
The study will follow participants over a period of time to assess outcomes such as overall survival, progression-free survival, and the occurrence of side effects. The trial aims to provide valuable information on the best treatment strategy for older patients with this type of cancer, ultimately helping to improve their quality of life and treatment outcomes.
