目的:探究胃癌根治术后手术部位感染(surgical site infection,SSI)影响因素及血清单核细胞趋化蛋白-1(monocyte chemoattractant protein-1,MCP1)、糖类抗原72-4(carbohydrate antigen 72-4,CA72-4)、可溶性白细胞分化抗原-14(soluble ...目的:探究胃癌根治术后手术部位感染(surgical site infection,SSI)影响因素及血清单核细胞趋化蛋白-1(monocyte chemoattractant protein-1,MCP1)、糖类抗原72-4(carbohydrate antigen 72-4,CA72-4)、可溶性白细胞分化抗原-14(soluble cluster of differentiation antigen-14,sCD14)水平变化意义。方法:选取2017年02月至2021年01月我院150例行胃癌根治术患者作为研究对象,根据患者术后是否出现SSI分为两组,感染组(n=35)与非感染组(n=115)。比较两组患者临床资料、手术前后血清MCP1、CA72-4、sCD14水平,分析胃癌根治术后SSI影响因素。绘制受试者工作特征曲线(receiver operating characteristic curve,ROC),评价胃癌根治术后血清MCP1、CA72-4、sCD14水平对SSI的诊断价值。分析术后血清MCP1、CA72-4、sCD14水平与感染程度(IPS评分)的相关性。比较术后血清MCP1、CA72-4、sCD14高水平与低水平患者病死率。结果:两组患者年龄、手术方式、临床分期、手术时间、糖尿病情况比较,差异有统计学意义(P<0.05)。感染组术后血清MCP1、CA72-4、sCD14水平高于非感染组(P<0.05)。Logistic回归方程结果显示,年龄、临床分期、糖尿病、手术方式、手术时间及术后血清MCP1、CA72-4、sCD14水平均为胃癌根治术后SSI的独立危险因素(P<0.05)。绘制胃癌根治术后血清MCP1、CA72-4、sCD14水平对SSI诊断价值的ROC曲线,结果显示胃癌根治术后血清MCP1、CA72-4、sCD14水平诊断SSI的曲线下面积(area under the curve,AUC)分别为0.804、0.768、0.777。应用Logistic二元回归拟合,构建各指标联合诊断的AUC,结果显示,联合检测的AUC为0.912。胃癌根治术后SSI患者IPS评分为(13.89±6.52)分。Pearson相关性分析可知,胃癌根治术后SSI患者血清MCP1、CA72-4、sCD14水平与感染程度呈正相关关系(P<0.05)。根据术后血清MCP1、CA72-4、sCD14水平分为高水平组与低水平组,术后血清MCP1、CA72-4、sCD14高水平组病死率明显高于低水平组,差异有统计学意义(P<0.05)。结论:胃癌根治术后SSI发病影响因素包括年龄、临床分期、糖尿病、手术方式、手术时间及术后血清MCP1、CA72-4、sCD14水平,且临床检测术后血清MCP1、CA72-4、sCD14水平,在SSI诊断、病情评估及预后预测中具有重要价值。展开更多
