Background/Aim: Receptor-interacting serine/ threonine-protein kinase 3 (RIP3) is a key component related to tumor necrosis factor-dependent necroptosis. RIP3 has been known to be a predictive biomarker in many types of carcinomas. We aimed to investigate whether RIP3 expression is correlated with clinicopathological characteristics and the outcomes of patients with breast carcinoma. Patients and Methods: We performed immunostaining for RIP3 and analyzed the association of RIP3 expression status with the clinicopathological characteristics and survival of 203 patients with invasive ductal carcinoma of the breast. Results: High RIP3 expression was significantly correlated with lymph node metastasis and human epidermal growth factor receptor 2 positivity. In patients with triple-negative breast carcinoma (TNBC), high RIP3 expression was an independent prognostic factor for disease-free survival (DFS). RIP3-high TNBC showed the lowest DFS rate. Conclusion: High RIP3 expression is associated with aggressive clinical behavior of breast carcinoma. Our data suggest that RIP3 serves as an independent prognostic factor in TNBC.
