Distribution of HLA antigens in breast cancer.
Investigation of various tumor-specific markers has a critical role in early diagnosis and treatment of breast cancer. The aim of the this study is to investigate the Human Leukocyte Antigen (HLA) alleles, the molecules that play an important role in immunity and tumor response of the body, and its relationship with breast cancer. In this prospective clinical study, after obtaining approval from the ethics committee of Istanbul University Experimental Medical Research Institute, 22 female patients who have been hospitalized in Istanbul University Cerrahpasa Faculty of Medicine the Department of General Surgery with a diagnosis of breast cancer were selected. In the control group, there were 22 healthy women who had no relationship and were donor candidates for renal transplantation. After collecting blood in 5 ml tubes with EDTA, HLA A, B and DR groups were measured with SSP method using the GenoVision Olerup SSP (Olerup SSP, Stockholm, Sweden) kit in Istanbul University Cerrahpasa Faculty of Medicine Blood Center Tissue Type Determination Laboratory. In patient and control group, totally 53 alleles; 17 alleles of HLA-A gene, 22 alleles of B gene, 14 alleles of DR gene were detected. A statistically significant relationship was determined between HLA-B55:01 and HLA-DRb1*18:01 alleles and the development of breast cancer (p<0.05). HLA-B13:01 antigen is determined only in the control group. It was concluded that HLA-B13:01 antigen, determined only in the control group, may be protective for breast cancer and HLA-B55:01 and HLA-DRb1*18:01 antigens, determined only in the patient group, may be a risk factor for breast cancer (Tab. 5, Ref. 22).
