摘要:

目的 探讨可溶性生长刺激表达基因2蛋白(sST2)与结直肠癌患者临床病理特征和预后的关系。方法 选取2017年5月—2020年5月南通大学附属海安医院结直肠癌患者101例。检测所有患者血清sST2水平,并收集其相关临床资料和实验室检测结果。采用受试者工作特征(ROC)曲线确定sST2判断结直肠癌患者预后(死亡)的最佳临界值。采用Kaplan-Meier生存曲线和Log-rank χ2检验评估结直肠癌患者的生存情况。采用Cox比例风险回归分析评估影响结直肠癌患者总生存期(OS)的危险因素。结果 ROC曲线分析结果显示,sST2判断结直肠癌患者预后(死亡)的最佳临界值为459 pg/mL。根据最佳临界值将所有患者分为sST2高水平(>459 pg/mL)组和sST2低水平(≤459 pg/mL)组。与sST2低水平组相比,sST2高水平组年龄、美国东部肿瘤协作组(ECOG)评分≥1分所占比例、TNM分期Ⅲ期所占比例显著升高(P<0.05),血红蛋白(Hb)水平、肿瘤分化程度显著降低(P<0.05)。Kaplan-Meier生存曲线分析结果显示,sST2高水平组OS显著短于sST2低水平组(Log-rank χ2=27.01,P<0.001)。多因素Cox比例风险回归分析结果提示,高ECOG评分、TNM分期Ⅱ期、TNM分期Ⅲ期、肿瘤分化程度(中低分化)和sST2升高(>459 pg/mL)是结直肠癌患者OS缩短的危险因素[风险比(HR)分别为1.99、2.32、4.09、1.39、1.59,95%可信区间(CI)分别为1.23~3.01、1.64~4.32、2.32~8.32、1.03~2.00、1.21~2.08,P<0.05]。结论 高sST2水平可促进结直肠癌进展,是预后不良的独立危险因素。sST2在结直肠癌预后评估中具有潜在的应用价值。

Abstract:

Objective To investigate the relationship between soluble growth stimulating gene 2(sST2) protein and clinicopathological features and prognosis in patients with colorectal cancer. Methods A total of 101 patients diagnosed with colorectal cancer in Hai'an Hospital of Nantong University from May 2017 to May 2020 were enrolled,and serum sST2 level was determined. Clinical data and clinical laboratory determination results were collected. The optimal cut-off value of sST2 for patient prognosis(death) was evaluated by receiver operating characteristic(ROC)curve. Patient survival state was evaluated by Kaplan-Meier survival curve and Log-rank χ2 test. Risk factors affecting overall survival(OS)were assessed using Cox proportional hazard regression analysis. Results The optimal cut-off value for sST2 was 459 pg/mL. The patients were classified into high sST2 group(>459 pg/mL)and low sST2 group(≤459 pg/mL). Compared with low sST2 group,age,the proportion of Eastern Cooperative Oncology Group(ECOG) score ≥1 and the proportion of TNM stage Ⅲ in high sST2 group were increased(P<0.05),and the hemoglobin(Hb) level and tumor differentiation degree were decreased(P<0.05). Kaplan-Meier survival curve indicated that the OS of high sST2 group was lower than that of low sST2 group( Log-rank χ2=27.01,P<0.001). Multivariate Cox proportional hazard regression analysis showed that ECOG score,TNM stage Ⅱ,TNM stage Ⅲ,moderate to poor tumor differentiation and sST2>459 pg/mL were associated with short OS [hazard ratios(HR) were 1.99,2.32,4.09,1.39,1.59,95% confidence interval(CI)1.23-3.01,1.64-4.32,2.32-8.32,1.03-2.00,1.21-2.08,P<0.05]. Conclusions High sST2 level promotes the progression of colorectal cancer and serves as an independent risk factor for poor prognosis. It can be potentially applied for the evaluation of patient prognosis.
