摘要:

目的 探究外周血转化生长因子β1(TGF-β1)/Smad蛋白家族(Smads)信号通路蛋白对乳腺癌改良根治术后感染的预测价值及影响因素。 方法 回顾性选取医院2023年1月至2025年6月收治的419例乳腺癌患者临床资料为研究对象,均行乳腺癌改良根治术治疗,根据患者术后感染情况将其分为感染组(62例)和非感染组(357例)。比较两组一般资料及TGF-β1/Smad信号通路相关蛋白水平,分析乳腺癌改良根治术后感染的影响因素及TGF-β1/Smads信号通路蛋白对乳腺癌改良根治术后感染的预测价值。 结果 感染组合并糖尿病患者占比及外周血单个核细胞TGF-β1、Smad2、Smad3蛋白水平高于非感染组,术后置管时间长于非感染组(P < 0.05)。合并糖尿病、术后置管时间较长及外周血单个核细胞TGF-β1、Smad2、Smad3蛋白水平较高均为乳腺癌改良根治术后感染的影响因素(OR= 3.751、1.244、1.422、1.411、1.449,P < 0.05)。TGF-β1、Smad2、Smad3蛋白联合预测乳腺癌改良根治术后患者感染曲线下面积(AUC)值高于三者单独检测(P < 0.05),其敏感度和特异度分别为72.58%、89.64%。 结论 乳腺癌改良根治术后感染的影响因素包括合并糖尿病、术后置管时间较长及外周血单个核细胞TGF-β1、Smad2、Smad3蛋白水平较高,同时外周血单个核细胞TGF-β1、Smad2、Smad3蛋白联合检测预测乳腺癌改良根治术后患者感染可在维持较高敏感度(72.58%)的同时,显著提高特异度(89.64%)。

Abstract:

Objective To explore the predictive value and influencing factors of peripheral blood transforming growth factor β1 (TGF-β1)/Smad protein family (Smads) signaling pathway proteins on infection after modified radical mastectomy for breast cancer. Methods From January 2023 to June 2025, the clinical data of 419 patients with breast cancer in the hospital were retrospectively selected as the research object, all of them were treated by modified radical mastectomy, and they were divided into the infection group (62 cases) and the non-infection group (357 cases) according to their postoperative infection. The general data and the levels of TGF-β1/Smads signaling pathway related proteins were compared between the two groups, and the influencing factors of infection after modified radical mastectomy and the predictive value of TGF-β1/Smads signaling pathway protein for infection after modified radical mastectomy were analyzed. Results The proportion of patients with diabetes mellitus and the levels of TGF-β1, Smad2 and Smad3 protein in peripheral blood mononuclear cells in the infected group were higher than those in the non-infected group, and the postoperative intubation time was longer than that in non-infected group (P < 0.05). Complication of diabetes mellitus, long postoperative intubation time and high levels of TGF-β1, Smad2 and Smad3 protein in peripheral blood mononuclear cells are all influencing factors of infection after modified radical mastectomy (OR = 3.751, 1.244, 1.422, 1.411, 1.449, P < 0.05). The area under infection curve (AUC) value of TGF-β1, Smad2 and Smad3 combined in predicting patients after modified radical mastectomy was higher than that of the three alone (P < 0.05), and their sensitivity and specificity were 72.58% and 89.64% respectively. Conclusions The influencing factors of infection after modified radical mastectomy for breast cancer included diabetes mellitus, long postoperative catheterization time and higher levels of TGF-β1, Smad2 and Smad3 protein in peripheral blood mononuclear cells. At the same time, the combined detection of TGF-β1, Smad2 and Smad3 protein in peripheral blood mononuclear cells to evaluate the infection of patients after modified radical mastectomy for breast cancer could maintain a high sensitivity (72.58%) and significantly improve the specificity (89.64%).
