Abstract:Objective To explore the application of P16/Ki-67 immunocytochemistry double staining in the diagnosis of cervical precancerous lesions for its accuracy.Methods A total of 900 patients with cervical precancerous lesions who were treated in our hospital from May 2016 to March 2017 were selected.Each patient was provided with P16/Ki-67 immunochemistry double staining assay and thinprep cytologic test(TCT)for human papilloma virus DNA.The positive rate of cervical precancerous lesions was detected using P16/Ki-67 immunochemistry double staining method.The pathological biopsy results were set as the gold standard,the accuracy of P16/Ki-67 immunochemistry double staining and TCT detecting cervical precancerous lesions was assessed.Results Among 900 participants,54 subjects were examined as positivity by pathological biopsy.The specificity and sensitivity of P16/Ki-67 immunocytochemistry double staining for cervical precancerous lesions were 82.3%(696/846)and 92.6%(50/54).By TCT,they were 68.6%(580/846)and 62.9%(34/54)respectively.Compared with the two examination methods,the specificity and sensitivity of P16/Ki-67 immunocytochemistry double staining were superior to those by TCT with significant differences(P<0.05).Conclusion The detection of P16/Ki-67 immunocytochemistry double staining can improve the diagnostic accuracy of cervical precancerous lesions in a definite effect,which is worthy of clinical promotion.
