Abstract:

Objective To investigate the relationship between preoperative peripheral blood red blood cell distribution width-to-platelet count ratio(RPR) and clinicopathological features and prognosis of patients with endometrial carcinoma(EC). Methods A retrospective analysis was conducted from September 2013 to October 2016 in the First People's Hospital of Shanzhou District. The clinical data of 123 EC patients(including 5-year follow-up results)were collected. Receiver operating characteristic(ROC) curve was used to evaluate the efficacy of RPR in diagnosing EC. Taking 0.193 as the optimal cut-off value,123 EC patients were classified into high RPR group(45 cases) and low RPR group(78 cases),and the clinicopathological features and prognosis of the 2 groups were compared. Cox regression analysis was used to investigate the prognostic factors of EC patients. Results The proportion of non-adenocarcinoma,maximum tumor diameter ≥2 cm,high the Federation International of Gynecology and Obstetrics(FIGO) stage,lymphovascular space infiltration,high differentiation,lymph metastasis,low pathological grade and recurrence cases in high RPR group were higher than those in low RPR group(P<0.05),and the 5-year overall survival rate(40.0%,18/45) was lower than that in low RPR group(73.1%,57/78)(P<0.05). The 5-year overall survival rate of EC patients with non-adenocarcinoma,maximum tumor diameter ≥2 cm,FIGO stage Ⅲ,lymphovascular space infiltration,high differentiation,lymph metastasis,recurrence and high RPR was decreased(P<0.05). Cox regression analysis showed that non-adenocarcinoma,recurrence,FIGO stage Ⅲ and high RPR were independent prognostic risk factors for EC patients(P<0.05). Conclusions RPR is related to clinicopathological progression in EC patients,and high RPR is an independent prognostic risk factor in EC patients.
