人类乳头瘤病毒及其亚型在新疆南部地区维族妇女宫颈癌组织中的分布

Distribution of human papillomavirus and its subtypes in tissue samples of Uigur cervical cancer from southern Xinjiang

目的:研究我国宫颈癌高发区新疆维吾尔自治区维族妇女宫颈癌发病与人类乳头状瘤病毒(HPV)的关系。方法:采用聚合酶链反应(PCR)技术对南疆维族宫颈癌新鲜组织及正常宫颈组织(各40例)进行HPV-C、HPV16、HPV18及HPV6/11的检测。结果:HPV-C、HPV16、HPV18及HPV6/11在宫颈癌组织中的阳性率分别为87.5%、72.5%、10.0%及0%,在维族对照组中的阳性率分别为20.0%、5.0%、0及7.5%,在HPV-C阳性的宫颈癌中HPV16阳性占82.8%。宫颈癌组织中HPV-C及HPV16的阳性率明显高于正常对照组,差异有显著性(P<0.001)。HPV16在宫颈鳞癌组织中的阳性率明显高于腺癌,而HPV18在宫颈腺癌中的阳性率明显高于鳞癌,HPV总感染率及HPV16阳性率在宫颈癌的各临床分期及病理组织分级之间无显著性的差异。结论:HPV感染与我国宫颈癌高发区新疆南部地区维族宫颈癌发病有密切相关.其中HPV16感染在南疆维族妇女宫颈癌发病中起主要的作用,HPV16主要与鳞癌有关,而HPV18与宫颈腺癌有关。HPV-C及HPV16感染与宫颈癌临床分期及病理分级无关。

Purpose:To study the association between human papillomavirus (HPV) and cervical cancer in Uigur women from southern Xinjiang where there is a high risk of cervical cancer.Methods:HPV-C,HPV16,HPV18 and HPV6/ 11 were detected in 40 fresh tissues of cervical cancer and 40 tissues of normal cervix by using polymerase chain reaction technique.Results:The positive rate of HPV-C,HPV16,HPV18 and HPV6/11 in fresh tissue of cervix cancer were 87. 5%,72.5%,10.0% and 0,respectively;The positive rate of HPV-C,HPV16,HPV18 and HPV6/11 in normal cervix were20.0%,5.0%,0 and 7.5%,HPV16 was the most common type in HPV-C positive patients with the rate of 82.8 %. The positive rate of HPV-C and HPV16 in cervical cancer were significantly higher than that in control groups;The positive rate of HPV16 in squamous cancer of cervix was significantly higher than that in adenocarcinomas of cervix;while the posi- tive rate of HPV 18 in adenocarcinomas of cervix was significantly higher than that in squamous cancer of cervix(P<0.01). The positive rates of HPV-C and HPV16 have no correlation with clinical stages and histological grade of cervical carcino- mas (P>0.05).Conclusions:HPV16 infection plays an important role in the carcinogenesis of cervical cancer of Uigur women from Southern Xinjiang,HPV16 infection is closely correlated with squamous carcinomas of cervix,while HPV18 infection is closely correlated with adenocarcinomas of cervix.The positive rate of HPV-C and HPV16 have no correlation with clinical stages and histological grade of cervical carcinomas.
