Abstract:
This paper is an overview of the French experience with contact X-ray radiation for rectal cancer. The analysis was mainly carried out on 50 years of experience in Lyon or since 1980 in the Centre Hospitalier Universitaire Lyon Sud. The results obtained in Dijon and Nancy are also reported. In early rectal cancer, contact X-ray radiation can play an important role in three different situations: (1) small T1 less than 2 cm: adjuvant contact X-ray radiotherapy after local excision; (2) T2 N0 or large T1: first-line contact X-ray radiotherapy combined with external beam radiotherapy (+/- chemotherapy) followed by surgery (anterior resection or local excision); (3) early T3 N0 in frail patients: the same approach as for T2 N0 with, in case of clinical complete response, local excision or follow-up.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
