Association of ABO blood group and breast cancer in Jodhpur.

ABSTRACT

There is a large amount of evidence that the ABO blood group system may play a role in disease etiology. However, in relation to breast cancer, these findings are inconsistent and contradictory. Present study was conducted for analysis to access ABO blood groups potential role of in breast carcinoma. The study was conducted on 206 clinically diagnosed breast cancer patients from Radiotherapy Department of Mathura Das Mathur Hospital in Jodhpur, from September 2006 to December 2007. The standard agglutination test was used to determine the blood groups. Association of ABO blood groups and risk of breast cancers was found out with Odd Ratios (ORs) with 95% Confidence Interval (CI). In reference of proportion of breast cancer in blood group AB [OR 1 with 95% CI 0.476 to 2.103), the breast carcinoma in blood group A [OR 7.444 with 95% CI 4.098 to 13.5222) was found at 7.4 times at higher risk than in blood group ‘AB’. Breast cancer was found minimum in blood group ‘AB’ and maximum in blood group ‘A’.
