摘要:

目的 探讨术前系统免疫炎症指数(systemic immune ⁃inflammation index,SII)与胰腺癌 pancreatic ductal adenocarcinoma,PDAC)患者预后的关系。方法 回顾性分析 2015 1 月至 2020 12 在郑州大学第二附属医院行胰腺癌切除术的 PDAC 患者相关临床资料,包括一般资料(年龄、性别、有无 基础疾病)、术前 1 周实验室检验结果(血常规、CA19⁃9、胆红素水平、肿瘤大小、有无淋巴结转移、肿瘤分 化程度)。根据公式(血小板计数×中性粒细胞/淋巴细胞)计算患者术前1周的SII;并采用ROC曲线来确定SII最佳临界值;利用Kaplan⁃Meier 绘制生存曲线;采用 Cox 单因素和多因素回归分析探讨术前SII PDAC 患者术后生存的关系。结果 本研究共纳入150例患者,年龄42.0 ~ 79.0岁,平均(60.4 ± 9.9)岁;其中男76 50.67%),女 74 例(49.33%)。根据 ROC 曲线得出的 SII 最佳分界值为 822,将 150 例患者分为两组:SII > 822(n = 71)和 SII ≤ 822(n = 79),利用 Kaplan⁃Meier 曲线计算出两组患者术后第 1、3、5 年的生存率分别为 39.7%、5.7%、0.0%)和(71.8%、37.2%、2.1%),平均生存时间分别为(14.88 ± 1.56)个月和(29.92 ± 2.02)个 月,SII ≤ 822组总生存率显著高于SII > 822组(P < 0.05)。Cox多变量生存分析显示,SII > 822、肿瘤> 3 cm 有淋巴结转移是影响胰腺癌患者术后预后的独立危险因素(P < 0.05)。结论 术前SII > 822、肿瘤> 3 cm 有淋巴结转移是影响胰腺癌患者术后总生存期有关,SII越高,患者的预后越差。

Abstract:

Objective To investigate the effect of preoperative systemic immune inflammation index(SII on postoperative prognosis of patients with pancreatic cancer(PDAC). Methods The clinical data of PDAC patients who underwent pancreatic cancer resection in the second affiliated Hospital of Zhengzhou University from January 2015 to December 2020 were analyzed retrospectively,including general data(age,sex,underlying disease)and the results of laboratory examination one week before operation(blood routine,CA19⁃9,bilirubin level,tumor size,lymph node metastasis,tumor differentiation). The SII of patients one week before operation was calculated according to the formula:the platelet count × the number of neutrophils/the number of lymphocytes. The best critical value of SII was determined by ROC curve,the survival curve was drawn by Kaplan⁃Meier,and the relationship between preoperative SII and postoperative survival was discussed by Cox univariate and multivariate regression analysis. Results This study included 150 patients,aged 42.0 ~ 79.0(60.4 ± 9.9)years,76 males(50.67%)and 74 females(49.33%). According to the ROC curve,the best cut⁃off value of SII was 822,above which there were 71 cases and under which there were 79. By Kaplan⁃Meier curve,the 1,3,5⁃year survival rates of the two groups were(39.7%,5.7%,0.0%)and(71.8%,37.2%,2.1%),respectively,the average survival time was(14.88 ± 1.56)months and(29.92 ± 2.02)months,respectively,and the overall survival rate of the SII ≤ 822 group was significantly higher than that of the SII > 822 group(P < 0.05). By Cox multivariate survival analysis,the indepen⁃ dent risk factors for their postoperative prognosis were SII > 822,tumor > 3 cm and lymph node metastasis(P < 0.05). Conclusion The independent risk factors affecting the overall survival of pancreatic cancer patients are preoperative SII > 822,tumor > 3 cm and lymph node metastasis. The higher the SII,the worse the prognosis.
