Objective To validate the colposcopy indication proposed by the 2019 ASCCP Risk-Based Management Consensus Guidelines for abnormal cervical cancer screening tests (the 2019 ASCCP guidelines). Methods Clinical data of 1404 patients who underwent colposcopy in single center in China were reviewed. Based on history and current cervical screening (HPV & cytology), corresponding recommendations were given according to the 2019 ASCCP guidelines. The agreement and discrepancy of colposcopy indication were analyzed between the Chinese consensus and the 2019 ASCCP guidelines. Results Colposcopy indication was matched in about 80% patients. The left 20% were recommended with follow-up by the 2019 ASCCP guidelines. The discrepancy mainly focused on patients having a current result of HPV-positive NILM without unknown history. The ratio of observed CIN3+ in our database over estimated CIN3+ by the 2019 ASCCP guidelines was 6.2 (31/5). The ratio was even higher in patients with HPV16/18-positive NILM (7, 28/4), compared with those with other types of high-risk HPV-positive NILM (3, 3/1). The 2019 ASCCP guidelines had a relatively high sensitivity (83.1%), a low specificity (21.5%), a low positive predictive value (14.1%) and a high negative predictive value (89.1%) for prediction of CIN 3+. Conclusions We could try to apply the 2019 ASCCP guidelines in Chinese population. The classification of HR-HPV was strongly recommended during risk assessment. For patients with HPV16/ 18 infection, colposcopy should be recommended. Perspective multi-center randomized controlled trial with reliable follow-up should be performed in the future to confirm the feasibility.
