Psychological State, Immunotherapy Response, and Multi-Omics Signatures in TNBC

The goal of this prospective observational study is to understand how psychological status influences the therapeutic response and long-term outcomes of patients with triple-negative breast cancer (TNBC) receiving neoadjuvant immunotherapy. The study primarily focuses on the association between psychological status and pathological complete response (pCR) as well as event-free survival (EFS). In this study, early-stage TNBC patients undergoing standard neoadjuvant immunotherapy will complete psychological assessments at baseline and multiple timepoints during treatment. Measurement include self-assessment questionnaires like GAD-7 and PHQ-9 and clinician-administered depression assessment scale like Hamilton Depression Rating Scale (HDRS). Blood and saliva samples will be collected to measure immune cell subsets, inflammatory cytokines, cortisol, and heart rate variability (HRV). Treatment response (pCR, ORR) and long-term outcomes (EFS) will be recorded and analyzed. By integrating psychological measures, circulating immune markers, and clinical efficacy endpoints, researchers aim to build a psychological-immune-response association model and identify psychophysiological biomarkers that may predict immunotherapy benefit.
