BACKGROUND

Breast cancer (BRCA) is the malignant tumor with the highest incidence rate among women in the world, and its mortality rate ranks second. The purpose of our study is to explore the correlation between caspase-1 () and the prognosis of BRCA patients and the potential mechanism of action, and to analyze the clinical value of combined with multimodal ultrasound features in early screening and prognosis of BRCA.

METHODS

We analyzed The Cancer Genome Atlas (TCGA) database to confirm that was expressed in BRCA patients and determine whether its expression was correlated with patient prognosis. The relationship between expression and survival was measured by the clinicopathological parameters. Multivariate analysis was performed using Cox regression, and a nomogram was developed using these results for quality assurance purposes. The correlations between and immune cells were investigated using the Tumor Immune Estimation Resource (TIMER) and TCGA databases. Next, we performed gene set enrichment analysis (GSEA) to determine the potential mechanism of action. Finally, to analyze the effect of combined with multimodal ultrasonography characteristics on the prognosis of BRCA patients was studied by analyzing the clinical data of patients.

RESULTS

expression was lower in BRCA tumor tissues than in the surrounding tissues. Patients with high expression had better overall survival (OS), disease-specific survival (DSS), and progression-free interval (PFI) than those with low expression. GSEA suggested that may affect the cell cycle, immune environment, inflammation, apoptosis, the HIPPOMERLIN pathway, Natural killer (NK) cell regulation of cytotoxicity, p53 expression, the Janus kinase-signal transducer and activator of transcription (JAK-STAT) pathway, the mitogen-activated protein kinase (MAPK) pathway, extracellular matrix, etc., thereby influencing the biological events in BRCA. Among conventional ultrasound features and contrast-enhanced ultrasound (CEUS) features, mass margin status and blood flow grade were associated with the expression of . Meanwhile, patients with poor ultrasound features tended to have low expression.

CONCLUSIONS

may be a novel predictive marker for BRCA patients. combined with multimodal ultrasound features has good clinical value in the early screening and prognostic prediction of BRCA.
