[Human papillomavirus genotype distribution in invasive squamous cell carcinoma of the uterine cervix in Mongolian women in inner Mongolia autonomy region]

To investigate the prevalence of human papillomavirus (HPV) and the HPV genotype distribution in invasive squamous cell carcinoma of the uterine cervix in the Mongolian women in Inner Mongolia autonomy region.The prevalence data of HPV in our department were retrospectively reviewed. INNO-LiPA genotyping technique was used to detect HPV genotypes in the reserved carcinoma tissue specimens.Totally 63 tissue specimens were collected and detected. The prevalence of HPV was 93.7%. The positive rates of HPV among different clinical staging and different pathological grading were not significantly different (P0.05). The prevalence of HPV16 was not significantly different among different age groups (P0.05). HPV16 (69.8%), HPV18 (4.8%), HPV31 (4.8%), HPV39 (4.8%), and HPV52 (3.2%) were the 5 dominating HPV genotypes in all cases.HPV infection is closely correlated with invasive squamous cell carcinoma of the uterine cervix in Mongolia women. HPV16 is the most important genotype in invasive squamous cell carcinoma of the uterine cervix, followed by HPV18, 31, and 39. HPV infection dose not affect the progression and differentiation of invasive squamous cell carcinoma of the uterine cervix.
