摘要:

目的 探讨治疗前血小板/淋巴细胞比值(PLR)、中性粒细胞/淋巴细胞比值(NLR)和淋巴细胞/单核细胞比值(LMR)预测前列腺癌患者预后的价值。方法 选取144例前列腺癌患者,收集所有患者的临床资料,在开始治疗前检测其血小板、淋巴细胞、单核细胞和中性粒细胞,计算PLR、NLR和LMR。对所有患者随访3年。采用Kaplan-Meier生存曲线分析前列腺癌患者的3年生存率。采用Cox回归分析评估PLR、NLR、LMR预测前列腺癌患者预后的价值。采用Pearson线性相关分析评估PLR、NLR、LMR与Gleason评分的相关性。结果 144例前列腺癌患者PLR、NLR和LMR分别为4.71(1.21~62.14)、4.77(1.34~57.41)、2.83(0.91~39.10)。根据3项指标的中位数分别分组。高PLR组、低LMR组3年总生存率、肿瘤无进展生存率和肿瘤特异生存率均分别低于低PLR组、高LMR组(P<0.001)。高NLR组与低NLR组之间3年总生存率、肿瘤无进展生存率和肿瘤特异生存率差异均无统计学意义(P>0.05)。Cox回归分析结果显示,高PLR、低LMR、年龄、饮酒史、高血压史、TNM分期是前列腺癌患者3年总生存率、肿瘤无进展生存率和肿瘤特异生存率的独立危险因素(P<0.05)。Pearson线性相关分析结果显示,PLR、NLR与Gleason评分均呈正相关(r值分别为0.26、0.23,P<0.01),LMR与Gleason评分呈负相关(r=-0.41,P<0.000 1)。结论 治疗前PLR和LMR可作为预测前列腺癌患者预后的指标,治疗前高PLR和低LMR的前列腺癌患者预后较差。

Abstract:

Objective To investigate the roles of pretreatment platelet/lymphocyte ratio(PLR),neutrophil/lymphocyte ratio(NLR) and lymphocyte/monocyte ratio(LMR) in the prognosis of prostate cancer patients. Methods The clinical data of 144 patients with prostate cancer were enrolled. Pretreatment platelet,lymphocyte,monocyte and neutrophil were determined. PLR,NLR and LMR were calculated. Patients diagnosed with prostate cancer were enrolled for a 3-year follow-up. Kaplan-Meier method was used for survival analysis. Cox regression analysis was used to evaluate the correlations between PLR,NLR and LMR with the prognosis of prostate cancer. The correlations between PLR,NLR and LMR with Gleason scores were analyzed by Pearson analysis. Results PLR,NLR and LMR of 144 prostate cancer patients were 4.71(1.21-62.14),4.77(1.34-57.41) and 2.83(0.91-39.10),respectively. The subjects were grouped according to the median of the measured values of the 3 indicators. In patients with high PLR and low LMR,the 3-year overall survival rate,progression-free survival rate and tumor-specific survival rate were decreased(P<0.001). There was no statistical significance in 3-year overall survival rate,progression-free survival rate and tumor-specific survival rate of prostate cancer patients between high and low NLR groups(P>0.05). Cox regression analysis showed that high PLR,low LMR,age,alcohol history,hypertension history and TNM stage were prognostic factors for 3-year overall survival rate,progression-free survival rate and tumor-specific survival rate in prostate cancer patients(P<0.05). Pearson analysis showed that there were positive correlations between PLR and NLR with Gleason score(r=0.26 and 0.23,P<0.01) and a negative correlation between LMR and Gleason score(r=-0.41,P<0.000 1). Conclusions PLR and LMR before treatment can be used as prognostic indicators for patients with prostate cancer,and patients with pretreatment high PLR and low LMR have poor prognosis.
