Factors Associated with Lesion Recurrence Following Cervical Conization.

To investigate the factors influencing lesion recurrence during the follow-up after cervical conization and evaluate the clinical value of human papillomavirus (HPV) testing and thinprep cytology test (TCT) in postoperative follow-up patients undergoing cervical conization.A total of 289 patients with cervical lesions who underwent primary cervical conization at our hospital between January 1, 2018, and December 31, 2019, were included in this study. TCT, HPV testing, and colposcopy were performed every 6 months for a follow-up period of 3 years. Based on the follow-up results, the patients were divided into recurrence and non-recurrence groups. The basic and colposcopic data of the two groups were analyzed to identify factors influencing lesion recurrence. Additionally, the clinical value of HPV testing and TCT in postoperative follow-up and recurrence diagnosis of patients undergoing cervical conization was assessed.The recurrence group showed significantly higher age of onset, concurrent rate of other chronic diseases, and parity, as well as a markedly lower barrier contraceptive rate compared to the non-recurrence group, with statistically significant differences (P < .05). In the recurrence group, the type III transformation zone (TZ) predominated (59.26%), which significantly differed from the non-recurrence group (P < .05). The detection rates of abnormal TCT findings and HPV infections in postoperative reexaminations were significantly higher in the recurrence group compared to the non-recurrence group (P < .05), whereas no significant differences were observed between the two groups before cervical conization (P > .05). Among the recurrence group (n = 54), 52 cases (96.3%) had HPV infections, and 29 cases (53.7%) had abnormal TCT findings, with a significantly higher detection rate for HPV infections (P < .05). The area under the receiver operating characteristic (ROC) curve (AUC) for HPV testing, TCT, and combined HPV testing with TCT after cervical conization were 0.861, 0.712, and 0.882, respectively. These results indicate that HPV testing alone performs similarly to combined HPV testing with TCT and significantly outperforms TCT alone in predicting lesion recurrence after cervical conization.Factors influencing lesion recurrence after cervical conization include patient age, barrier contraceptive rate, concurrent rate of other chronic diseases, parity, and type of transformation zone. HPV testing alone is more sensitive and accurate than TCT in predicting lesion recurrence during postoperative follow-up of patients undergoing cervical conization. This finding can reduce missed diagnoses and provide a significant theoretical basis for postoperative follow-up of patients undergoing cervical conization.
