摘要:

目的:评估我国医院医生的阴道镜拟诊和组织病理学结果的一致性以及其对宫颈上皮内瘤变(cervical intraepithelial neoplasia,CIN)2+患者的检出能力,为不同等级医院选择阴道镜引导宫颈活检的合适阈值提供参考。方法:运用系统综述的方法(非传统意义的系统综述),收集2005年12月—2020年5月我国公开发表的18篇报道中11 973例来自医院阴道镜门诊患者的临床信息,包括就诊医院等级、阴道镜拟诊和组织病理学诊断结果,分析选择不同活检阈值对CIN2+患者的检出效果。结果:11 973例患者的阴道镜拟诊和组织病理学结果的总体一致率为68.35%,最低为53.33%,最高为86.87%。三级医院进行的14项研究9 419例患者的总一致率为70.22%,高于基层医院(二级和一级医院)进行的4项研究2 554例患者的总一致率(61.43%),差异有统计学意义(P<0.000 1)。此外,以阴道镜诊断低度鳞状上皮内病变及以上(low-grade squamous intraepithelial lesion or worse,LSIL+)为活检阈值,我国医院检出CIN2+的总体敏感度和特异度分别为86.11%和64.72%;三级医院检出CIN2+的敏感度和特异度分别为87.87%和65.60%,均高于基层医院的80.09%和61.39%,差异有统计学意义(P<0.000 1);以阴道镜诊断高度鳞状上皮内病变(high-grade squamous intraepithelial lesion or worse, HSIL+)为活检阈值,我国医院检出CIN2+的总体敏感度和特异度分别为68.37%和94.63%,三级医院检出CIN2+的敏感度和特异度分别为70.19%和95.51%,均高于基层医院的62.16%和91.30%,差异有统计学意义(P<0.000 1)。结论:我国医院阴道镜拟诊和组织病理学结果的总体一致率有待提高,且不同医院间变异范围较大,提示不同医院间的诊断水平存在差异。综合考虑我国阴道镜医生的资源匮乏和诊断能力不足,建议选择以LSIL+为活检阈值引导宫颈活检发现更多的CIN2+,降低不必要的漏诊,可能更具现实意义。

Abstract:

Objective: To assess the agreement between colposcopic diagnosis and histopathology from Chinese doctors, and the colposcopic diagnostic ability of cervical intraepithelial neoplasia (CIN)2+ cases for providing a reference on appropriate choice of guided colposcopy-biopsy threshold for different hospital levels. Methods: By using the method of systematic review (non-traditional way), 18 published literatures from December 2005 to May 2020 in China, including clinical information of 11 973 patients from cervical department of hospitals were analyzed to obtain hospital grades, colposcopic diagnosis and histopathology and to evaluate its usefulness in detecting CIN2+ cases under different biopsy thresholds. Results: The overall agreement between colposcopy and histopathology for 11 973 patients was 68.35%, the lowest was 53.33%, the highest was 86.87%. The agreement in 14 tertiary hospitals of 9 419 patients was 70.22%, higher than 61.43% in 4 primary hospitals of 2 554 patients. There was statistically difference among both hospital levels(P<0.000 1). Moreover, when the biopsy threshold was LSIL+, the overall sensitivity and specificity of CIN2+ detection in Chinese hospitals were 86.11% and 64.72%; the sensitivity and specificity of CIN2+ detection were 87.87% and 65.60% respectively in the tertiary hospitals, higher than 80.09% and 61.39% in primary hospitals with statistical significance(P<0.000 1). When the biopsy threshold was HSIL+, the overall sensitivity and specificity of CIN2+ detection were 68.37% and 94.63%; the sensitivity and specificity of CIN2+ detection were 70.19% and 95.51%, respectively in tertiary hospitals, higher than 62.16% and 91.30% in primary hospitals with statistical significance(P<0.000 1). Conclusions: The overall agreement between colposcopy and histopathology in Chinese hospitals should be improved, and there is a wide range of variation, suggesting different diagnostic levels between both hospitals in China. Using LSIL+ as the biopsy threshold is a highly sensitive indicator for detecting CIN2+. Considering the lack of medical resources and diagnostic ability of colposcopists in China, it is suggested that LSIL+ as the biopsy threshold to guide cervical biopsy for detecting more CIN2+ and reducing unnecessary missed cases may be of more practical significance.
