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.
