Abstract:
【Objective】 To investigate the predictive value of preoperative platelet/lymphocyte ratio (PLR) and neutrophil/lymphocyte ratio (NLR) (NLR-PLR) in peripheral blood for the prognosis of patients with upper urinary tract urothelial carcinoma (UTUC) undergoing radical surgery. 【Methods】 The clinical data of 104 UTUC patients who underwent radical nephroureterectomy plus bladder sleeve resection in our hospital during Jan.2015 and Dec.2020 were retrospectively analyzed. The receiver operating characteristic (ROC) curve was drawn according to NLR and PLR, the optimal cut-off values of NLR and PLR were calculated, and NLR-PLR was determined accordingly. The patients were divided into NLR-PLR group 1 (PLR ≥161.46 and NLR≥ 2.51) and NLR-PLR group 0 (remaining patients). Chi-square test was used for comparison between groups, and the Kaplan-Meier method was used to draw survival curves. According to the Cox univariate and multivariate risk regression models, the risk factors for decreased overall survival (OS) were determined. 【Results】 The optimal cut-off values of PLR and NLR were 161.46 and 2.51, respectively. There were 74 patients in the NLR-PLR group 0 and 30 in the NLR-PLR group 1. Cox multivariate regression analysis showed that T stage, maximum tumor diameter and NLR-PLR were independent risk factors for reduced OS (P<0.05). 【Conclusion】 Preoperative NLR-PLR is a potential predictor of the prognosis of UTUC patients. Higher NLR-PLR is associated with poorer prognosis.
