摘要
目的研究妇女生殖道感染高危型人乳头瘤病毒(HR—HPV)的载量与各级子宫颈上皮内瘤变(CIN)的关系。方法汇总1999--2008年间在我国6个城市地区和8个农村地区开展的以人群为基础的子宫颈癌筛查横断面研究的数据。共有18186名17~59岁的妇女参加了筛查,并收集子宫颈脱落细胞用于HR—HPVDNA检测。采用第2代杂交捕获试验(hc2),病毒载量由样本的相对光单位与标准阳性对照之比(RLU/PC)来衡量。根据HR-HPV载量,除阴性组[0,1.00)以外,将阳性对象分为3组:低度载量[1.0,10.00),中度载量[10.00,100.00)和高度载量≥100.00。子宫颈病变按照病理诊断分为正常、轻度宫颈上皮内瘤变(CIN1)、中度宫颈上皮内瘤变(CIN2)、重度宫颈上皮内瘤变(CIN3)和子宫颈癌(SCC)。采用非条件多项式logistic回归分析病毒载量与子宫颈病变级别的关系。结果HR-HPV感染率为14.51%(2515/17334),其中100.00%(29/29)的SCC、97.63%(206/211)的CIN3、93.43%(199/213)的CIN2、75.04%(421/561)的CIN1和10.17%(1660/16320)的正常妇女HR—HPVDNA检测阳性。HR—HPV感染阳性的SCC、CIN3、CIN2、CIN1和宫颈正常妇女的病毒载量中位数分别是320.85、158.05、143.70、125.34和9.64。各级病变中病毒载量的分布差异有统计学意义(χ^2=6190.40,P〈0.01);病毒载量越高,CIN程度越高(χ^2=5493.35,P〈0.01)。低、中和高度载量组与阴性组相比,发生各级CIN的危险性均增加[OR(95%CI):CIN1为9.01(6.31-12.87)、24.96(18.23—34.17)和68.42(51.40—91.08),CIN2为26.44(12.07—57.95)、98.53(49.54~195.98)和322.88(168.62—618.27),CIN3+为72.89(24.02~221.18)、343.58(121.81—969.09)和〉999.99(473.38-〉999.99)],有明显的剂量反应关系�
Objective To determine the association between viral load of high risk human papillomavirus (HR-HPV) and cervical intraepithelial neoplasia (CIN). Methods Cervical exfoliated cells were collected from 18 186 women aged 17 -59 from six urban areas and eight rural areas when they were screened in the cross-sectional population-based studies from 1999 to 2008. HR-HPV was detected by the Hybrid Capture 2 (hc2) system, and viral load was measured by the ratio of relative light units to standard positive control (RLU/PC). RLU/PC was categorized for analysis into four groups : negative [ 0, 1.00), low viral load [ 1.0, 10. 00 ), moderate viral load [ 10. 03,103.00 ), and high viral load t〉 1130. 03. Ceryical lesions were diagnosed by biopsies as normal,CIN 1,CIN 2,CIN 3 and squamous cervical cancer ( SCC ). Association between HR-HPV viral load and CIN was evaluated by unconditional muhinomial logistic regression. Results The HR-HPV infection rate of the population was 14. 51% (2515/17 334). 103. 00% (29/29) of SCC,97. 63% (206/211) of CIN 3,93.43% (199/213) of CIN 2,75. 04% (421/ 561 ) of CIN 1 and 10. 17% ( 1660/16 320) of normal women were positive for HR-HPV DNA. The median RLUs for the HR-HPV positive women with SCC, CIN 3, CIN 2, CIN 1 and normal were 320. 85,158. 05, 143.70,125.34 and 9. 64, respectively. There were significant differences among the distributions of viral loads in each lesion ( χ^2 = 6190. 40, P 〈 0.01 ). The severity of CIN increased with the viral load ( χ^2 = 5493.35 ,P 〈0. 01 ). Compared with the risks of CINs in HR-HPV negative population,the risks of CINs in low ,moderate and high viral loads were increased gradually [ OR(95% CI) : CIN 1 : 9.01 ( 6. 31 - 12. 87 ), 24.96(18.23 -34. 17) and 68.42(51.40 -91.08); CIN 2:26.44(12.07 -57.95),98.53(49.54- 195.98) and 322. 88 ( 168.62 - 618.27 ) ; CIN 3 + : 72. 89 (24. 02 - 221.18 ) ; 343.58 ( 121.81 - 969. 09 ) and 〉 999. 99 ( 473.3
