摘要
目的 探讨控制营养状态(CONUT)评分和相关炎性指标在肾透明细胞癌(ccRCC)患者预后预测中的价值,为临床更好地评估病情及制定个体化治疗方案提供参考.方法 回顾性分析2010-2018年宜宾市4所综合性医院收治的132例ccRCC患者的病历资料和生存情况,采用受试者工作特征曲线(ROC)分析CONUT评分及炎性指标中性粒细胞和淋巴细胞比值(NLR)、血小板和淋巴细胞比值(PLR)以及淋巴细胞和单核细胞比值(LMR)预测患者预后的曲线下面积和最佳截断值,Kaplan-Meier法绘制生存曲线,采用Log-rank检验和Cox回归分析影响预后的因素.结果 患者中位随访时间62(53,71)个月,随访期内死亡37例(28.03％),疾病特异性生存期(DSS)和无进展生存时间(PFS)分别为51(41,58)个月和46(35,56)个月,患者3、5年DSS分别为84.09％和71.97％,3、5年PFS分别为75.00％和71.97％.CONUT评分、NLR、PLR以及LMR预测患者预后的ROC曲线下面积(AUC)分别为0.980、0.905、0.899和0.884,最佳截断值分别为3.50分、3.19、89.07和3.56.多因素Cox回归分析显示:CONUT 评分和 PLR 与患者 DSS 有关,其 HR(95％CI)分别为 0.042(0.013～0.140)和 0.182(0.045～0.744);CONUT 评分和LMR与患者PFS有关,其HR(95％CI)分别为0.029(0.010～0.086)和2.984(1.227～7.258).结论 ccRCC患者预后与机体营养、免疫和炎症状况有关,CONUT评分和炎症相关指标(PLR、LMR)可能是患者DSS和PFS的重要预测因子.
Abstract
Objective To explore the value of controlling nutritional status(CONUT)score and related inflammatory indicators in predicting the prognosis of clear cell renal cell carcinoma(ccRCC)patients,to provide a reference for better clinical assessment and individualized treatment plan.Methods A retrospective study was conducted on 132 patients with ccRCC admitted to four comprehensive hospitals in Yibin during 2010 and 2018.Patients'medical and follow-up records were collected,and receiver operating characteristic(ROC)curve was drawn to analyze the area under the curve(AUC)and optimal cut-off value of CONUT score and related indicators.Survival curve was plotted with Kaplan-Meier method,and the influencing factors of prognosis were analyzed with Log-rank test and Cox regression.Results During the follow-up of 62(53,71)months,37(28.03％)deaths occurred.The disease-specific survival(DSS)and progression-free survival(PFS)were 51(41,58)and 46(35,56)months,respectively.The 3-year and 5-year DSS and PFS were 84.09％and 71.97％,and 75.00％and 71.97％,respectively.The AUC of CONUT score,neutrophil to lymphocyte ratio(NLR),platelet to lymphocyte ratio(PLR),and lymphocyte to monocyte ratio(LMR)were 0.980,0.905,0.899 and 0.884,respectively,with the optimal cut-off values of 3.50,3.19,89.07 and 3.56,respectively.Cox regression showed that CONUT score(HR=0.042,95％CI:0.013-0.140)and PLR(HR=0.182,95％CI:0.045-0.744)were associated with DSS;CONUT score(HR=0.029,95％CI:0.010-0.086)and LMR(HR=2.984,95％CI:1.227-7.258)were associated with PFS.Conclusion The prognosis of ccRCC patients is related to their nutritional,immune,and inflammatory status.CONUT score and inflammatory factors(PLR,LMR)may be important predictors of DSS and PFS.
