Role of MRI in rectal cancer staging
Mohammed Redia Abd-Alraheem;
Abstract
Rectal cancer is one of the most common causes of cancer cases all over the world. Its highest incidence is found in industrialized developed countries and its lowest incidence is found in developing countries.
Adenocarcinomas account for the vast majority (more than 67%) of rectal cancer, mucinous adenocarcinomas account for 20% (most aggressive type).
Despite advances in the diagnosis and treatment of rectal cancer, fiveyear survival rates continue to hover around the 50% mark. For cancers limited to the bowel wall, the survival rate climbs to 83%-90%, and drops to less than 10% if there are distant metastases, highlighting the importance of early detection and treatment.
Treatment is either surgical excision which is the total mesorectal excision (TME) alone (free resection margin) or neoadjuvant therapy followed by TME (involved resection margin).
