| 以病理组织学诊断为金标准，比较宫颈癌筛查中5%醋酸染色肉眼观察法(VIA)、薄层液基细胞学(LBC)、人乳头瘤病毒(HPV)自体采样法和HPV医生采样法的预测值。首先采用联合假设检验方法比较四种筛检方法的阳性预测值(PPV)和阴性预测值(NPV)，并对两预测值进行组间两两比较，再采用边际回归法和加权最小二乘法分别比较该两预测值，多重性调整采用Hochberg法。结果表明HPV医生采样法的NPV最高，LBC的PPV最高，均为有效的宫颈癌初筛方法，但后者需要有经验的细胞病理学家读片。HPV自体采样法的PPV和NPV均高于VIA，其PPV与HPV医生采样法相当，NPV与LBC相当，因该方法易得到受检者配合而有可能提高筛查依从性，成为一种简便、客观、易于重复和适宜在资源贫乏地区使用的宫颈癌初筛方法。 |

| To compare the predictive values of 5% acetic acid stain and visual inspection,human papillomavirus (HPV) Self test, ThinPrep Pap and HPV direct test in screening for cervicalcancer with biopsy as gold standard. Positive predictive values and negative predictive values werecompared simultaneously by joint hypothesis tests and then either positive predictive values ornegative predictive values of the any two screening tests were compared by marginal regression basedon both GEE and weighted least square methods. Hochberg method was used for multiplicityadjustment. It was showed that HPV direct test had the highest negative predictive value and ThinPrepPap the highest positive predictive value. 5% acetic acid stain and visual inspection had both thelowest positive predictive value and negative predictive value. Both HPV direct test and fhinPrep Papwere effcient, but the latter required compatible infrastructure and skilled caregivers to go with. Both5% acetic acid stain and visual inspection were inexpensive, and their positive predictive value andnegative predictive value were lower than HPV self-test. They also had similar positive predictivevalue with HPV direct test and similar negative predictive value with ThinPrep Pap. HPV self-testappeared to be efficient, suggesting that it had significant potential for screening program to beimplemented in the rural areas of China since the test could be performed without speculumexamination in low-resource regions |
