高危型人乳头瘤病毒杂交捕获法Ⅱ评估宫颈上皮内瘤变的临床价值

目的探讨高危型人乳头瘤病毒杂交捕获法Ⅱ(HC2)评估宫颈上皮内瘤变的临床价值。方法回顾性分析了2002年3月至今在我院妇科门诊进行宫颈液基薄层细胞学(TCT)检测和HC2二联筛查的723例患者,以及其中进行TCT、HC2和阴道镜下多点活检三联检查的350例患者的临床资料。结果在TCT和HC2二联筛查的723例患者中,不典型鳞状细胞(ASC)组、低度鳞状上皮内病变(LSIL)组和高度鳞状上皮内病变(HSIL)组高危型HPV感染率分别为70·7%(94/133)、88·9%(249/280)和90·9%(90/99),均明显高于TCT正常组的55·5%(117/211)(P=0·005,P<0·001,P<0·001)。在TCT、HC2和阴道镜加点活检三联检查的350例患者中,宫颈轻度不典型增生(CIN1)组和宫颈中度不典型增生(CIN2)组高危型HPV感染率分别为88·9%(72/81)和96·3%(52/54),均明显高于病理学结果正常组的77·7%(153/197)(P=0·03,P=0·002);宫颈重度不典型增生(CIN3)组和子宫颈癌组高危型HPV感染率分别为91·7%(11/12)和100·0%(6/6),也呈明显升高趋势。在三联检查TCT为ASC的患者群中,高危型HPV感染率为79·3%(69/87)。其中高危型HPV感染者发生CIN2-3的比率为38·0%,明显高于无高危型HPV感染者的5·9%(P=0·04)。结论高危型HPV感染与宫颈癌前病变及子宫颈癌密切相关,其感染率随宫颈病变严重程度呈上升趋势。

Clinical evaluation of high-risk HPV detection by hybrid capture II in screening cervical intraepithelial neoplasma

OBJECTIVE: To evaluate the value of high-risk HPV (hrHPV) detection by Hybrid Capture II (HC2) in screening cervical intraepithelial neoplasm (CIN). METHODS: Totally 723 patients who had received a dual screening with thinprep cytologic test (TCT) and HC2 in our department were analyzed retrospectively. Among them, 350 patients received a triple examination with TCT, HC2, and colposcopic biopsy. RESULTS: Among the 723 patients, the incidences of hrHPV infection with atypical squamous cell (ASC), low squamous intraepithelial lesion, and high squamous intraepithelial lesion were 70.7% (94/133), 88.9% (249/280), and 90.9% (90/99), respectively, significantly higher than 55.5% (117/211), the incidence of hrHPV infection with normal cytological results (P = 0.005, P < 0.001, P < 0.001, respectively). Among 350 cases who were received triple examination, the incidence of hrHPV infection with cervical intraepithelial neoplasia (CIN) 1 and CIN 2 were 88.9% (72/81) and 96.3% (52/54), significantly higher than 77.7% (153/197), the incidence of hrHPV infection with normal pathological results (P = 0.03, P = 0.002); The incidence of hrHPV infection with CIN 3 and squamous cancer were 91.7% (11/12) and 100.0% (6/6), also higher than normal cases. Among these 350 cases, the incidence of hrHPV infection with ASC was 79.3% (69/87). The incidence of CIN 2-3 with ASC and hrHPV infection was 38.0%, significantly higher than the incidence of CIN 2-3 with ASC and without hrHPV infection (5.9%) (P = 0.04). CONCLUSION: hrHPV infection has a close relation with CIN, and the incidence of hrHPV infection increases along with the severity of CIN.
