摘要:

目的 探讨治疗前纤维蛋白原联合血小板与淋巴细胞比值评分(F-PLR评分)及淋巴细胞与单核细胞比值(LMR)对接受新辅助免疫治疗联合化疗后行根治性手术的食管癌患者生存预后的预测价值。方法 回顾性分析2020年1月至2023年12月于内蒙古医科大学附属医院接受新辅助免疫治疗联合化疗后行食管癌根治术的113例患者的临床资料。通过受试者操作特征(ROC)曲线计算纤维蛋白原、血小板与淋巴细胞比值(PLR)和LMR预测总生存期(OS)的最佳截断值, 根据F-PLR评分及LMR最佳截断值分别对患者进行分组。组间临床病理特征比较采用χ2检验, 采用Kaplan-Meier法绘制生存曲线并行log-rank检验, 采用Cox比例风险回归模型进行单因素及多因素预后分析。结果 ROC曲线分析显示, 纤维蛋白原、PLR、F-PLR和LMR预测OS的曲线下面积分别为0.635、0.710、0.757和0.757, 纤维蛋白原、PLR和LMR最佳截断值分别为3.71 g/L、129.19和4.36。不同F-PLR评分(0分60例、1分34例、2分19例)患者的肿瘤长度(χ2=8.56, P=0.014)、临床分期(χ2=9.16, P=0.010)、T分期(χ2=10.27, P=0.006)差异均有统计学意义。高LMR(≥4.36, 40例)与低LMR(<4.36, 73例)患者的吸烟史(χ2=5.72, P=0.017)和临床分期(χ2=4.51, P=0.034)差异均有统计学意义。Kaplan-Meier曲线生存分析显示, F-PLR评分为0、1、2分的患者中位无进展生存期(PFS)分别为未达到、34个月、26个月, 中位OS分别为未达到、35个月、29个月, 差异均有统计学意义(χ2=8.46, P=0.015;χ2=21.32, P<0.001)。高LMR与低LMR组患者的中位PFS分别为未达到、34个月, 中位OS分别为未达到、37个月, 差异均有统计学意义(χ2=4.56, P=0.033;χ2=18.44, P<0.001)。单因素分析结果显示, 肿瘤部位(HR=0.52, 95%CI为0.28~0.97, P=0.041)、临床分期(HR=5.71, 95%CI为2.84~11.48, P<0.001)、T分期(HR=2.49, 95%CI为1.28~4.85, P=0.007)、N分期(HR=4.38, 95%CI为2.27~8.48, P<0.001)、PLR(HR=2.43, 95%CI为1.30~4.53, P=0.005)、F-PLR评分2分(HR=2.86, 95%CI为1.31~6.26, P=0.008)均是接受新辅助免疫治疗联合化疗后行根治性手术食管癌患者PFS的影响因素;病理类型(HR=3.46, 95%CI为1.41~8.51, P=0.007)、临床分期(HR=5.66, 95%CI为2.69~11.92, P<0.001)、T分期(HR=5.01, 95%CI为2.05~12.29, P<0.001)、N分期(HR=2.90, 95%CI为1.42~5.92, P=0.003)、纤维蛋白原(HR=2.69, 95%CI为1.34~5.42, P=0.005)、PLR(HR=4.27, 95%CI为2.01~9.05, P<0.001)、F-PLR评分1分(HR=5.62, 95%CI为2.17~14.54, P<0.001)、F-PLR评分2分(HR=6.46, 95%CI为2.36~17.65, P<0.001)、LMR(HR=0.05, 95%CI为0.01~0.35, P=0.003)均是接受新辅助免疫治疗联合化疗后行根治性手术食管癌患者OS的影响因素。多因素分析结果显示, 肿瘤部位(HR=0.36, 95%CI为0.19-0.71, P=0.003)和N分期(HR=2.85, 95%CI为1.05~7.73, P=0.040)均是接受新辅助免疫治疗联合化疗后行根治性手术食管癌患者PFS的独立影响因素, T分期(HR=4.34, 95%CI为1.51~12.42, P=0.006)和LMR(HR=0.06, 95%CI为0.01~0.48, P=0.008)均是接受新辅助免疫治疗联合化疗后行根治性手术食管癌患者OS的独立影响因素。结论 治疗前LMR对接受新辅助免疫治疗联合化疗的食管癌患者的OS具有预测价值, F-PLR评分并不是接受新辅助免疫治疗联合化疗的食管癌患者PFS或OS的独立影响因素。

Abstract:

Objective To explore the predictive value of the pre-treatment fibrinogen combined with platelet-to-lymphocyte ratio (F-PLR) score and the lymphocyte-to-monocyte ratio (LMR) for the prognosis of patients with esophageal cancer receiving radical surgery after neoadjuvant immunotherapy combined with chemotherapy. Methods A retrospective analysis was conducted on the clinical data of 113 patients diagnosed with esophageal cancer and underwent radical esophageal cancer surgery after neoadjuvant immunotherapy combined with chemotherapy at the Affiliated Hospital of Inner Mongolia Medical University from January 2020 to December 2023. Optimal cut-off values for fibrinogen, platelet-to-lymphocyte ratio (PLR), and LMR in predicting overall survival (OS) were determined by receiver operator characteristic (ROC) curve analysis. Patients were stratified into groups based on the F-PLR score and LMR optimal cut-off. Between-group comparisons of clinicopathological characteristics were performed using the chi-square test. The survival curve was plotted using the Kaplan-Meier method, with differences assessed via the log-rank test. Univariate and multivariate prognostic analysis was conducted using Cox proportional hazards regression model. Results ROC curve analysis showed that the areas under the curve (AUCs) for fibrinogen, PLR, F-PLR score, and LMR were 0.635, 0.710, 0.757, and 0.757, respectively. The optimal cut-off values were 3.71 g/L for fibrinogen, 129.19 for PLR, and 4.36 for LMR. Patients with different F-PLR scores (0 point, n=60; 1 point, n=34; and 2 points, n=19) showed statistically significant differences in tumor length (χ2=8.56, P=0.014), clinical stage (χ2=9.16, P=0.010), and T stage (χ2=10.27, P=0.006). There were statistically significant differences in the levels of LMR (≥4.36, n=40; <4.36, n=73) among patients with different smoking history (χ²=5.72, P=0.017) and clinical stage (χ²=4.51, P=0.034). Kaplan-Meier analysis revealed that the median progression-free survival (PFS) for patients with F-PLR scores of 0, 1, and 2 points were not reached, 34 months, and 26 months, respectively, and the median OS were not reached, 35 months, and 29 months, respectively, with statistically significant differences (χ²=8.46, P=0.015; χ²=21.32, P<0.001). The median PFS for the high-LMR group and low-LMR group were not reached and 34 months, respectively, and the median OS were not reached and 37 months, respectively, with statistically significant differences(χ²=4.56, P=0.033; χ²=18.44, P<0.001). Univariate analysis showed that tumor location (HR=0.52, 95%CI:0.28-0.97, P=0.041), clinical stage (HR=5.71, 95%CI:2.84-11.48, P<0.001), T stage (HR=2.49, 95%CI:1.28-4.85, P=0.007), N stage (HR=4.38, 95%CI:2.27-8.48, P<0.001), PLR (HR=2.43, 95%CI:1.30-4.53, P=0.005), and F-PLR score of 2 (HR=2.86, 95%CI:1.31-6.26, P=0.008) were the influencing factors of PFS in patients with esophageal cancer who underwent radical surgery following neoadjuvant immunotherapy combined with chemotherapy, while pathological type (HR=3.46, 95%CI:1.41-8.51, P=0.007), clinical stage (HR=5.66, 95%CI:2.69-11.92, P<0.001), T stage (HR=5.01, 95%CI:2.05-12.29, P<0.001), N stage (HR=2.90, 95%CI:1.42-5.92, P=0.003), fibrinogen (HR=2.69, 95%CI:1.34-5.42, P=0.005), PLR (HR=4.27, 95%CI:2.01-9.05, P<0.001), F-PLR score of 1 (HR=5.62, 95%CI:2.17-14.54, P<0.001), F-PLR score of 2 (HR=6.46, 95%CI:2.36-17.65, P<0.001), and LMR (HR=0.05, 95%CI:0.01-0.35, P=0.003) were the influencing factors of OS in these patients. Multivariate analysis showed that tumor location (HR=0.36, 95%CI:0.19-0.71, P=0.003) and N stage (HR=2.85, 95%CI:1.05-7.73, P=0.040) were independent influencing factors for PFS, whereas T stage (HR=4.34, 95%CI:1.51-12.42, P=0.006) and LMR (HR=0.06, 95%CI:0.01-0.48, P=0.008) were independent influencing factors for OS in patients with esophageal cancer who underwent radical surgery following neoadjuvant immunotherapy combined with chemotherapy. Conclusions Pre-treatment LMR has predictive value for OS, while the F-PLR score is not an independent influencing factor for either PFS or OS in patients with esophageal cancer receiving neoadjuvant immunotherapy combined with chemotherapy.
