ABSTRACT

Background There are currently few prognostic models for conization in patients with high-grade squamous intraepithelial lesion (HSIL) because it is a rapid procedure that typically collects less case information. The present study aimed to establish a rapid/accurate postoperative prognostic assessment model for these patients. Methods This study included 631 nonpregnant participants with HSIL confirmed by histopathology from January 2015 to January 2018. The recurrent/residual cervical intraepithelial neoplasia (CIN) were divided into residual CIN, simple recurrent CIN and recurrent CIN accompanied with CIN progression. The recurrence/residual-free survival (RFS) time was defined as the time span from the time of surgery (baseline) until the first lesion of CIN was detected or the 1-/3-/5-year follow-up endpoint was reached. Results After LASSO regression selection, the higher platelet-to-lymphocyte ratio (PLR) (OR = 1.006, p = 0.002), positive margin status (OR = 2.451, p = 0.021), HPV-16 (OR = 4.414, p < 0.001), −18 (OR = 3.040, p = 0.009), −56 (OR = 10.715, p=0.021), and non-HR-HPV (OR = 2.487, p = 0.028) infection showed significant difference in the Logistic model. And HPV-16 infection (OR = 6.159, p = 0.001) could promote recurrent CIN accompanied with CIN progression. In multivariate Cox regression models, the higher PLR (HR = 1.005/1.005/1.005, p = 0.020/0.002/0.003) and HPV-16 infection (HR = 2.758/2.836/2.674, p < 0.001) showed statistical difference during 1-/3-/5-year follow-up. While gland invasion (p = 0.081), margin status (p = 0.075) and HPV infection genotype (p = 0.150) did not showed statistical difference in multivariate Cox regression models based on LASSO regression. And gland invasion (p = 0.251/0.686) and HPV-58 infection (p = 0.148/0.813) also showed no statistical difference in optimized Logistic regression models. Conclusion HPV-16, −18, −56 and non-HR-HPV infection status can be considered as indicators for recurrent CIN during the 5-year follow-up, especially for HPV-16 infection, which also lead to a CIN recurrence accompanied with disease progression. And the preoperative PLR level, gland invasion, positive margin may be predictors for recurrent/residual CIN during 1-, 3- and 5-year follow-up.
