Abstract
Pathologists play an important role in the treatment of rectal cancer, interacting closely with all members of the multidisciplinary team including surgeons, oncologists and radiologists. In particular, pathologists play a crucial feedback role to surgeons, allowing them to audit the quality of surgical dissection, as well as to radiologists, allowing them to audit the accuracy of pre-operative staging. It is vital that a comprehensive and accurate report is issued for rectal cancer resections, which identifies the key prognostic features oncologists require to guide adjuvant treatment. Rectal cancer resections need to be handled appropriately at the time of specimen dissection to ensure that all possible prognostic features are correctly identified and reported. Tissue blocks should be carefully selected to allow accurate staging of the disease and to identify key high-risk features such as circumferential resection margin (CRM) involvement, extra-mural vascular invasion (EMVI) and peritoneal involvement. Many rectal cancer patients, particularly those with locally advanced disease, are now offered neoadjuvant radiotherapy ± chemotherapy. Responses to therapy vary markedly, and the pathologist can indicate the degree of response using a qualitative tumour regression grade. Low rectal cancer treated by abdominoperineal excision (APE) continues to have poorer outcomes than higher rectal tumours treated by anterior resection. This is believed to be related to differences in the anatomy of the low rectum and the surgical approach utilised. Pathologists have played a crucial role in the study of this important area and have led the call for a change in surgical approach to such tumours.
