Abstract: BACKGROUND: Inherited ABO blood group has been shown to play an important role in the pathogenesis of various gynecological cancers including endometrial carcinoma (EC). OBJECTIVE: Our study aimed to determine the prevalence of ABO blood groups in Iranian patients with EC and to investigate the relationship between the blood group and several clinicopathologic parameters in Imam Hossein Hospital. METHODS: One hundred and seventy-five EC patients were selected and analyzed for their clinicopathologic details including ABO blood group, age, menopausal status, body mass index (BMI), tumor grade, and stage of the International Federation of Obstetrics and Gynecology (FIGO). RESULTS: Endometrioid carcinoma was the most common histological type in this case study. Early stages (I and II) were present in 135 individuals (77.1%) and advanced stages (III and IV) appeared in 40 (22.9%) patients. Blood group A was prominent in patients with EC. There was a significant relationship between blood group A and cancer grade (P= 0.024). 23.1% of group A had grade III EC, while this grade appeared in 35.2% of the non-A blood group. There was no significant association between ABO blood groups and other EC clinic-pathological results (P> 0.05). CONCLUSION: Although there was no significant relationship between the ABO blood group and the patients’ clinicopathological characteristics, more studies could provide extensive information about any possible relation between the blood group, especially blood group A, EC, and the grade of the tumor.
