Abstract:
Background and purpose:Duffy blood group(DBG)system contains genotype system and phenotype system.DBG phenotype system is embodied by the protein carrying blood group antigens on the surface of red blood cells.Epidemiological evidence has shown that different races had definitely different DBG phenotype disuribution and there is a variation of morbidity and mortality of breast cancer among different race populations.Therefore,this study was to investigate whether DBG phenotype affects breast cancer occurrence and malignancy.Methods:We investigated DBG phenotypes of 253 female cases with breast diseases who were consecutively hospitalized in the Shanghai Cancer Hospital and analysis was done on its relationship with clinical pathological diagnosis.DBG phenotypes were examined by indirect antiglobulin-test with anti-Fya and anti-Fyb reagents,and were classified into Fya+Fyb-,Fya-Fyb+,Fya+Fyb+,Fya-Fyb-according agglutination.Results:Neither DBG phenotypes distribution difference existed in breast disease patients nor in breast cancer patients as observed in the general Chinese Han population.Fya-Fyb-and Fya-Fyb+ demonstrated more susceptibility to breast cancer than Fya+Fyb-and Fya+Fyb+,but there was no statistical significant difference.Fya-group(57.14%)had more malignant incidence than that of Fya+ group(39.02%),but there was also no statistical significance(P=0.28).No significant differences have been observed in ER,PR,Her-2 status and P53,PCNA,PS2,nm23,P450 status between every DBG phenotypes,nor in tumor grades in various DBG phenotypes.More patients were involved in axillary lymph nodes metastasis in Fya-than that in Fya+ group and reached statistical significance(100% and 39.13% respectively,P
