摘要
This study aims to investigate the distribution of HLA-A genes and identify alleles related to cervical cancer.A total of 252 cervical cancer patients (56 Han ethnic and 196 Uyghur ethnic) and 213 controls (103 Han ethnic and 110 Uyghur ethnic) were recruited in this study. HLA-A alleles were examined by polymerase chain reaction with sequence-specific primers. The frequencies of different HLA-A alleles were compared between the two ethnic groups as well as patients and controls. The correlation of HLA-A frequencies with various clinical characteristics and short-term treatment efficacy was analyzed.(1) Significantly higher frequencies of HLA-A*03:01 and HLA-A*03:02 and lower frequencies of HLA-A*11:01, HLA-A*24:02, and HLA-A*30:01 were observed in the Uyghur control groups than in Han control groups (P ≤ 0.05). (2) The frequency of HLA-A*01:01 in patients was significantly higher than controls. In contrast, the frequencies of HLA-A*30:01 and HLA-A*33:03 were lower in patients (P ≤ 0.05). (3) The frequency of HLA-A*30:01 in Han patients was lower than Han control group (P ≤ 0.05). However, there was no statistically significant in the frequency of HLA-A between Uyghur patients and controls (P > 0.05). (4) There was no significant association between HLA-A alleles and HPV16 or squamous cell carcinoma antigen levels (P > 0.05). (5) The frequency of HLA-A*30:01 allele in complete response + partial response group was higher than stable disease + progressive disease group (P ≤ 0.05).People from two ethnic groups displayed different HLA-A gene distribution. HLA-A*30:01 and HLA-A*33:03 alleles are the protective factors to cervical cancer patients from Xinjiang while HLA-A*01:01 serves as the susceptible gene.
