8、不同TNM分期老年胃癌患者临床特征及术后并发肠漏的影响因素。方法回顾性分析2 0 19年3月至2 0 2 2 年3月上海交通大学医学院附属新华医院收治的2 0 0 例老年胃癌患者的临床资料，根据TNM分期将其分为I/I组（n=68）、/V 组（n=132）,比较两组临床特征性别、年龄、分化程度、浸润深度、有无转移、癌胚抗原（CEA）、糖类抗原199（CA199）磷酸化蛋白激酶B(PKB/AKT）、脾酪氨酸蛋白激酶（Syk）蛋白表达情况】。另根据术后是否并发肠漏将其分为并发组（n=114）、非并发组（n=86）。对两组一般资料（包括性别、年龄、肿瘤直径、TNM分期、手术方式、是否合并脏器切除、术
9、中出血量、术前血红蛋白、白蛋白进行比较,将其中有明显差异的变量纳入多因素Logistic回归分析,筛选出影响老年胃癌患者术后并发肠漏的独立危险因素。结果/I V组低分化程度、黏膜层以下、淋巴结转移、远处转移、PKB/AKT阳性表达占比及CEA、CA 199水平分别为55.30%、6 6.6 7%、7 4.2 4%、43.18%、7 9.55%、(22.411.36）n g/m L、(37.551.8 9）U/m L,均高于I/I组14.7 1%、6.6 2%、17.6 5%、2.9 4%、57.35%、（7.150.62）n g/m L、（2 0.0 51.2 7）U/m L,Sy k 阳性表
10、达占比为12.8 8%，低于I/I组（39.7 1%），差异均有统计学意义（P0.05）。经Pearson检验发现，TNM分期与浸润深度、有淋巴结转移、有远处转移、CEA高表达、CA199高表达、PKB/AKT阳性表达均呈正相关（r=0.8170.820、0.8 14、0.8 55、0.8 2 6.0.8 34，P 0.0 5），与分化程度、Syk阳性表达均呈负相关（r=-0.802、-0.8 11，P 0.0 5）。并发组肿瘤直径为（5.48 1.45)cm，长于非并发组（3.140.8 3)cm,胸腹联合手术、合并脏器切除占比及术中出血量分别为35.0 9%、2 9.8 2%、（331.7
11、 0 2 7.46)mL，均高于非并发组4.6 5%、16.28%、（2 0 4.6 514.2 0)m L)，术前血红蛋白、术前白蛋白水平分别为（115.12 10.8 5）、（34.57 4.8 9）g/L，均低于非并发组（134.3111.8 7）、（42.50 5.8 5）g/L，差异均有统计学意义（P0.05）。多因素Logistic回归分析结果显示,肿瘤直径4cm以上、胸腹联合手术、合并脏器切除、术中出血量2 7 0 mL以上、术前血红蛋白12 5g/L以下、术前白蛋白38.5g/L以下均为老年胃癌患者术后并发肠漏的独立危险因素（0 R=4.536、5.0 7 3、4.47 3、4
12、.7 7 3、4.18 7、4.90 9，P0.05）。结论不同TNM分期老年胃癌患者的临床特征存在一定差异,TNM分期与分化程度、浸润深度、有无转移、肿瘤标志物水平、基因蛋白表达相关；肿瘤直径、手术方式、合并脏器切除、术中出血量、术前营养指标均为老年胃癌患者术后并发肠漏的危险因素，临床应采取相应措施予以改善。【关键词】TNM分期胃癌临床特征肠漏影响因素基金项目：国家自然科学基金资助项目（编号：8 2 17 30 8 1）*通讯作者：赵黎,E-mail:文章编号：16 7 1-46 9 5(2 0 2 3)15-16 0 5-0 4:1606:Clinical characteristics
