ABSTRACT
Objective To investigate the clinical value of preoperative lymphocyte-to-monocyte ratio(LMR)in evaluating the prognosis of patients with stage T1 non-muscle invasive bladder cancer(NMIBC).Methods A total of 215 patients with stage T1 NMIBC who underwent transurethral resection of bladder tumor were enrolled.Clinical data were collected.Patients were followed up and their disease-free survival(DFS)and overall survival(OS)were recorded.The receiver operating characteristic(ROC)curve of preoperative LMR in detecting patient prognosis was used to determine the optimal cut-off value for LMR.Patients were divided into low LMR group(LMR <3.86,=77)and high LMR group(LMR ≥ 3.86,=138).Kaplan-Meier survival curves were explored to compare cumulative DFS and OS rates in patients with different LMR levels,and COX proportional hazards regression model was used to analyze factors associated with DFS and OS.Results All these 215 patients with T1 stage NMIBC were followed up for 2-92 months,and the DFS rate was 59.07% and OS rate was 65.12%.Kaplan-Meier curves showed that the cumulative DFS rate(=4.784,=0.029)and cumulative OS rate(=7.146, =0.008)in the low LMR group were significantly lower than those in the high LMR group.Tumor size ≥ 3 cm(=1.398,95%1.042-1.875,=0.025),pathological grade G3(=1.266,95%1.026-1.563,=0.028),and LMR ≥ 3.86(=2.347,95%1.080-5.101,=0.031)were independent factors associated with DFS in patients with stage T NMIBC.In addition,tumor size ≥ 3 cm(=1.228,95%1.015-1.484,=0.034),pathological grade G3(=1.366,95%1.017-1.834,=0.038),and LMR<3.86(=2.008,95%1.052-3.832,=0.035)were independent factors associated with OS in patients with T1 stage NMIBC. Conclusion Preoperative LMR is an independent factor associated with patients' prognosis in T1 stage NIMBC.Patients with low LMR tend to have higher risk of NMIBC progression and death.
