Objectives: To evaluate the predictive significance of neutrophil-lymphocyte ratio and platelet-lymphocyte ratio in the prognosis of high-grade endometrial carcinoma and to establish a novel predictive model. Design: A retrospective multicenter study. Setting: Fifteen hospitals of the Chinese Endometrial Carcinoma Consortium. Population: This study included 910 high-grade epithelial endometrial carcinoma patients from the multicenter who underwent initial surgical treatment between January 1, 2005, and December 31, 2019. Methods: Data was retrospectively obtained from the medical records and follow-up information of patients. Cox proportional hazard regression models were developed to predict the risk of recurrence and death at 3, 5, and 10 years, and the models were validated and calibrated. The area under the curve was used to measure the predictive performance of the model. Main outcomes measures: Disease-free survival and overall survival. Result: Platelet-lymphocyte ratio and neutrophil-lymphocyte ratio were risk factors for recurrence, and neutrophil-lymphocyte ratio was a risk factor for death. We established models for predicting death and recurrence. In the validation cohort, the area under receiver operating characteristic curve of disease-free survival model at 3,5 and 10 years was 0.72, 0.77, 0.77, and of overall survival model was 0.72, 0.81, and 0.84. Kaplan–Meier survival analysis showed a significant difference between low-risk and high-risk groups. Conclusions: Neutrophil-lymphocyte ratio and platelet-lymphocyte ratio are risk factors affecting the prognosis of high-grade endometrial carcinoma patients. This novel prediction model for high-grade endometrial carcinoma can provide accurate postoperative risk classification and prognosis prediction for patients.

Objective Explore the difference of oncology outcome of laparotomy and laparoscopy in the new FIGO2018 stage of early cervical squamous cell carcinoma without any high risk pathological factors. Methods The 5-years OS and DFS of cervical squamous cell carcinoma undergoing laparotomy and laparoscopy from 2004 to 2018 were compared by the total study population and propensity score from China. Result There was no difference in 5-year OS between laparotomy (2,478 cases) and laparoscopy (1,504 cases), but the 5-year DFS of laparotomy was higher (92.2 %vs. 90.4%, P=0.022). Cox analysis showed that laparoscopy was not an independent risk factor for the death of cervical squamous cell carcinoma (OS: P=0.598), but it was an independent risk factor for the recurrence/death (HR = 1.468,95% CI 1.131 ~ 1.906, P=0.004). There was no difference in 5-year OS between laparotomy (2,391 cases) and laparoscopy (1,495 cases) after 1:2 PSM, but the 5-year DFS of laparotomy was higher (92.7% vs. 90.8%, P = 0.006), Cox analysis showed that laparoscopy was not an independent risk factor for the death of cervical squamous cell carcinoma (OS： P=0.521), but it was an independent risk factor for the recurrence/death (HR=1.512, 95%CI 1.151~1.971, P=0.002). Conclusion There is no difference in 5-year OS between these groups for early cervical squamous cell carcinoma in new stage of FIGO2018 without any high-risk pathological factors, the 5-year DFS of laparotomy is higher than that of laparoscopy group, and laparoscopy is an independent risk factor for recurrence/death, so laparoscopy has a higher risk of recurrence.
