Real-world Treatment Outcomes and Safety of Neoadjuvant Pembrolizumab-containing Therapy in Patients With Triple-negative Breast Cancer: Korean Nationwide Multicenter Study (Pembro-Real World)

There is a need for research analyzing treatment response, long-term clinical outcomes, and the patterns of short- and long-term immune-related adverse events in TNBC patients who have received neoadjuvant chemotherapy including pembrolizumab in a real-world clinical setting. This study aims to provide real-world evidence by comprehensively analyzing pathological response, recurrence patterns, survival outcomes, and treatment-related adverse events in TNBC patients who received pembrolizumab-based neoadjuvant chemotherapy in actual clinical practice. These findings are expected to provide important evidence for validating clinical trial results in real-world clinical settings and optimizing future treatment strategies for TNBC patients.
