ABSTRACT
The problem of colonic carcinoma is still a dilemma regarding, diagnostic and therapeutic strategy. Many factors have been found to affect the incidence of this type of cancer such as age, sex, diet and previous abdominal surgery. A survey study revealed that in normal [control] population HLA-A1 was positive in about 50%. HLA-B7 was positive in about 8% and HLA-DR11 was positive in about 40%. The aim of this study was to find a relation between the above-mentioned types of HLA and the increased or decreased risk of incidence of colonic carcinoma. Thirty patients were diagnosed after using careful history taking, clinical examination, laboratory, and radiological investigations. Finally colonoscopy and biopsy were done. Detection of [HLA- A1. B7] was done serologically using Sigma USA. Detection of [HLA-DR 11] was done using lymphobeads method [Biotest Great Britain [UK] Itd]. HLA-A1 was found to be positive in eight patients while HLA-B7 was positive in seven patients, and HLA-DR 11 was positive in ten patients. HLA-A1 positive results were associated with increased risk of incidence of colonic carcinoma by 45%, while HLA-B7 positive results were associated with increased risk of incidence by 233% and presence of HLA-DR11 positive results were associated with decreased risk incidence by 80%. So we can consider the above-mentioned HLA types as new factors affecting the incidence of colonic carcinoma
