In this study, SPSS 20.0 software (IBM Corp., Armonk, NY, USA) was used for descriptive statistical analysis of the perioperative clinicopathological characteristics of LELC. Survival and prognosis information collected during follow-up was analyzed using Kaplan-Meier method to calculate overall survival (OS) and progression-free survival (PFS). Log-rank test was used to evaluate the significance of OS and PFS. Cox regression analysis was performed for univariate and multivariate factors affecting the prognosis. Statistical significance was considered when P<0.05.
