ObjectivesTo determine the application value of thinprep cytologic test (TCT) combined with serum carbohydrate antigen 153 (CA153) and carbohydrate antigen 50 (CA50) detection in the early diagnosis and screening of cervical cancer and precancerous lesions.MethodsA total of 187 females with cervical lesions admitted to Shanghai 7th People's Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from January 2017 to December 2018 were selected and divided into two groups: the cervical cancer group and the cervical precancerous lesion group, with 16 cases in the cervical cancer group and 171 cases in the cervical precancerous lesion group (cervical precancerous lesions were divided into 63 cases of the CNI group, 59 cases of the CNII group and 49 cases of the CNIII group). During the same period, 106 healthy females were selected as the healthy group. The serum tumor markers CA153 and CA50 of all subjects were detected by chemiluminescence method; The diagnostic value of TCT combined with serum CA153 and CA50 in cervical cancer and precancerous lesions was analyzed with colposcopy pathological diagnosis results as gold standard; ROC curve was drawn to evaluate the diagnostic value of serum TCT, CA153 and CA50 in cervical cancer and precancerous lesions.ResultsThe levels of serum CA153 and CA50 in the cervical cancer group were significantly higher than those in the cervical precancerous lesion group and the healthy group (p< 0.05), and the levels of serum CA153 and CA50 in the cervical precancerous lesion group were significantly higher than those in the healthy group (p< 0.05). The sensitivity of TCT, serum CA153 and serum CA50 in the single detection of cervical cancer and precancerous lesions was 95.93%, 97.54% and 96.00%, the specificity was 59.41%, 60.23%, 60.12%, the accuracy was 74.74%, 75.77%, 75.43%, the positive predictive value was 62.03%, 63.64%, 63.10%, and the negative predictive value was 96.22%, 97.17% and 95.28%, respectively. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of TCT combined with serum CA153 and CA50 were 96.77%, 73.19%, 85.67%, 80.21% and 95.28%, respectively. ROC curve showed that the area under the curve (AUC) of TCT and serum CA153 and CA50 in the single detection of cervical cancer and precancerous lesions was 0.791, 0.864 and 0.787, respectively, the AUC of combined detection of TCT and serum CA153 and CA50 in patients with cervical cancer and precancerous lesions was 0.877, which was significantly higher than that of single detection (p< 0.05).ConclusionsTCT combined with serum CA153 and CA50 has been reported as a treatment regimen with high accuracy, which has a high diagnostic efficiency for early diagnosis of cervical cancer and precancerous lesions, and can significantly improve the sensitivity.Copyright: © Pakistan Journal of Medical Sciences.
