DWI in assessing aggressiveness of Rectal cancer
Muhammad Yusuf Abd El-Kader;
Abstract
Colorectal cancer is the third most commonly occurring cancer in men and second most commonly occurring cancer in women. There is wide geographical variation in incidence with rates varying ten-fold in both sexes worldwide. About two thirds of colorectal cancer cases occur in countries characterized by high or very high incidences of development and/or income.
Adenocarcinomas account for the majority of rectal cancer, mucinous adenocarcinoma the most aggressive type.
The prognosis of rectal cancer is directly related to a number of factors:
o Depth of tumor invasion (local tumor extent) (T stage).
o The number of metastatic lymph nodes (N stage).
o Distant metastases (M stage).
o Tumor involvement in the circumferential resection margin (CRM).
Despite advances in the diagnosis and treatment of rectal cancer, five year survival rates are around 50%. For cancers limited to the rectal wall, the survival rate climbs to 83%-90%, and drops
