Pilot Study of Neoadjuvant Chemotherapy Combined With Immunotherapy and Multimodal Thermal Therapy for HER2-negative Breast Cancer

Summary

In this study, breast cancer (BC) patients eligible for inclusion will be divided into two groups according to molecular typing and subtyping, which combined immunotherapy and multimodal thermal therapy with conventional neoadjuvant chemotherapy, to explore methods of immune induction for BC, enhance the efficacy of immunotherapy, and accumulate data for subsequent stages of clinical study.
