Objective  To study the clinical significance of gasdermin-D(GSDMD) and caspase-1 expressions in the invasive ductal breast carcinoma. Methods  Seventy-seven female patients with invasive ductal carcinoma of breast performed radical resection in the 904th Hospital of Joint Logistic Support Force of PLA from January 2015 to June 2016 were selected as the research object. The expressions of GSDMD and caspase-1 protein in cancer tissues and 20 adjacent tissues were detected by immunohistochemistry, and their correlation with clinicopathological features was analyzed. Kaplan-Meier analysis was used to draw the survival curve, and log-rank test was used for univariate survival analysis, and Cox proportional hazards regression analysis of prognostic factors in patients with breast invasive ductal carcinoma. Results  The proportion of high expression of GSDMD and caspase-1 protein in adjacent tissues were significantly higher than those in breast cancer tissues (P<0.05). Univariate analysis results showed that the survival time of patients with invasive ductal carcinoma of breast were correlated with lymphatic metastasis, TNM staging, and the expression status of progesterone receptor, GSDMD, caspase-1 and Ki-67 (P<0.05). Multivariate analysis results showed that the low expression of GSDMD protein [HR=4.096, 95%CI (1.102, 15.216), P<0.05] and low expression of caspase-1 protein [HR=3.945, 95%CI (1.062, 14.652), P<0.05] were the independent risk factor that affect the survival rate of patients with invasive ductal carcinoma of breast. Conclusion  The low expression of GSDMD and caspase-1 protein in invasive ductal carcinoma of breast are independent risk factors for postoperative survival.
