The possible Association of HLA Class II with Bladder Cancer in Iraqi Patients

Abstract

Background: - Genetic Factors have a major role in the development of bladder cancer.
Objectives: - This study was carried out to shed a light on the possible association of HLA class II antigens and BC patients and to correlate this finding with the family
history.
Patients and Methodes :- Lymphocytotxicity assay had been used to assess HLAtyping of 65 BC patients and 50 healthy controls.
Results:- comparison between BC patients and healthy controls showed several antigens deviations in their frequencies. HLA-DR1, HLA-DQ1 and HLA-DQ3 antigens
were observed with increased frequencies in patients group with significant differences (P=0.000, 0.000 and 0.017 respectively). Moreover there was decrease frequency of
HLA-DR7 in patients group (P=0.010). Stastical analysis showed non significant correlation of the specific HLA –Ags with family history.
Conclusions: - This finding demonstrated that HLA-DR1, DR7, DQ1 and DQ3 might play a role in BC susceptibility.
