Distribution of HLA-DRB1 allele polymorphism in the Uyghur women with family history of cervical cancer / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To study the distribution of HLA-DRB1 allele polymorphism in Uyghur women with family history of cervical cancer, and provide theoretical evidence for detection and follow-up of high risk persons for cervical cancer by detection of HLA-DRB1 allele polymorphism.</p><p><b>METHODS</b>The HLA-DRB1 13 alleles were detected in 1000 Uyghur women, all from Hotan Moyu county Karsay village by using polymerase chain reaction sequence-specific oligonucleotide (PCR-SSO) assay.</p><p><b>RESULTS</b>The frequencies of HLA-DRB1*15 in women with family history of cervical cancer (17.3%), mother (18.0%) and other relatives except mother (17.0%) who had suffered from cervical cancer were significantly higher than that in the control group (9.7%, all P < 0.05). The frequencies of HLA-DRB1*04 in women with family history (16.8%) and other relatives except mother (20.7%) were significantly higher than that in the control group (12.7%, all P < 0.05). The frequencies of HLA-DRB1*03 in women with family history (2.6%) and other relatives except mother (1.1%) were significantly lower than that in the control group (6.3%, all P < 0.01). The frequencies of HLA-DRB1*12 in women with family history of cervical cancer (2.3%) and mother suffered from cervical cancer (1.5%) were significantly lower than that in the control group (5.7%, all P < 0.05).

In general, the distribution of HLA-DRB1 allele polymorphism in women with family history of cervical cancer is similar to that reported in abroad. The results of this study support the role of susceptible and protective HLA gene detection in screening high risk persons for this cancer among Uyghur women from cervical cancer high risk areas in Xinjiang.</p>

[Study on the distribution of HPV subtypes in Uighur people living in the Karsay township, Moyu county, Xinjiang].

OBJECTIVE: To study the distribution of human papilloma virus (HPV) subtypes in Uyghur people from the high risk region of cervical cancer in Xinjiang. METHODS: 21 subtypes of HPV from 400 cases of men's swabs of penile and 400 cases of women's cervix swabs were detected, using flow-through hybridization and gene chip technology. RESULTS: (1) The positive rate of HPV among the 400 women cases was 14.25%, with HPV16 the most common type. In women whose HPV was positive, the positive rate of HPV16 was 66.67%. The ranking of frequencies on the HPV subtypes in women were:HPV16, 58, 39, 18, 33, 52, 43, 66, CP8304, HPV6 and 11. (2) Among the 400 male cases, the positive rate of HPV was 8.00%, with HPV16 the most common type. In men whose HPV was positive, the rate of HPV16 was 44.44%. The ranking of HPV subtypes in men were HPV16, 43, 33, 39, 6 (HPV39 and 6 are equivalent) and 53. (3) Both wives and husbands were infected by different subtypes of HPV, the positive rate was relatively low among men whose wife's HPV were positive. However, the HPV positive rate was relatively low among women whose husband's HPV were positive. The concordance infection rate of women and men were 7.02% and the concordance infection rate of men and women were 9.38%. CONCLUSION: The HPV positive rates were relatively low in both men and women living in the region with high risk of cervical cancer in Xinjiang. However, the positive rate of high risk types HPV and HPV16 in both men and women were relatively high. Uyghur men seemed to have played a certain role related to the carcinogenesis of cervical cancer. HPV16 was the main type in both men and women in Xinjiang.
