Study of the Relationship between ABO Blood Group Types and Breast Cancer and Cervix Cancer in Khuzestan Province, Iran

Abstract

Background: Breast cancer and cervix cancer are the prevalent and deadly types of solid tumors around the world. According to the importance of cancer, it is necessary to understand predisposing factors that affect cancer risk. In this regard, previous studies suggest that blood types particularly ABO and Rh-Hr Blood-Group System could play roles in the risk and different features of cancers. In the present study, we aimed to evaluate the potential of ABO and Rh blood groups as risk factors for breast cancer and cervix cancer.
 Materials and Methods: A retrospective study included 109 and 14 patients diagnosed with breast cancer and cervix cancer, respectively with known ABO and Rh blood types, between 2018 and 2020 in Khuzestan province, Iran. For compression of ABO blood groups distribution between the cancer patients group and the healthy population, we used data from a large-scale study that report the distribution of ABO blood groups in 29,922 blood donors in Khuzestan province.
 Results: Based on obtained results the most frequent blood group is O followed by B, A, and AB in breast cancer and followed by A, B, and AB in cervix cancer. Results showed no significant association between ABO and Rh and the risk of breast and cervix cancer. Moreover, there is no relationship between blood types and clinic pathological features of breast cancer. 
 Conclusion: Based on our data, ABO and in this regard, previous studies suggest that blood types particularly ABO and Rh-Hr Blood-Group System could play roles in the risk and different features of cancers. In the present study, we aimed to evaluate the potential of ABO and Rh blood groups as risk factors for breast cancer and cervix cancer do have not any association with the risk of breast and cervix cancer and their characteristics.
