Tumors are believed to emerge only when immune surveillance fails. We wished to ascertain whether the failure to inherit putative protective alleles of HLA class II genes is linked to the development of breast cancer. We molecularly typed HLA DPB1, DQB1, DRB1, and DRB3 alleles in 176 Caucasian women diagnosed with early-onset breast cancer and in 215 ethnically matched controls. HLA DQB03032 was identified in 7% of controls but in no patients with early-onset breast cancer (P = 0.0001). HLA DRB111 alleles were also significantly overrepresented (P < 0.0001) in controls (16. 3%) as compared with patients with early-onset breast cancer (3.5%). HLA DQB03032 and HLA DRB111 alleles may have a protective role in human breast cancer.
人们认为肿瘤只有在免疫监视功能失效时才会出现。我们希望确定未能遗传假定的HLA II类基因保护等位基因是否与乳腺癌的发生有关。我们对176名被诊断为早发性乳腺癌的白种女性以及215名种族匹配的对照者进行了HLA DPB1、DQB1、DRB1和DRB3等位基因的分子分型。在7%的对照者中发现了HLA DQB03032,但早发性乳腺癌患者中未发现(P = 0.0001)。与早发性乳腺癌患者(3.5%)相比,HLA DRB111等位基因在对照者(16.3%)中也显著富集(P < 0.0001)。HLA DQB03032和HLA DRB111等位基因可能对人类乳腺癌具有保护作用。
