Cellular immunotherapy (CI), particularly chimeric antigen receptor-engineered T (CAR-T) cells, has emerged as a promising approach for addressing this challenge. In the wake of their striking efficacy against hematological cancers, CAR-T cells have also been used where the clinical need is greatest – in patients with aggressive BCs. Unfortunately, current outcomes fall considerably short of replicating that success, primarily owing to the scarcity of tumor-specific antigens and the immunosuppressive microenvironment within BC. Herein, we provide an up-to-date overview of both preclinical and clinical data concerning the application of CAR-T cell therapy in BC. By surveying the existing literature, we discuss the prevailing constrains of this therapeutic approach and overview possible strategies to advance it in the context of breast malignancies. Possible approaches include employing synthetic biology to refine antigen targeting and mitigate off-target toxicity, utilizing logic-gated CAR constructs to enhance specificity, and leveraging armored CARs to remodel the tumor micro-environment. Temporal and spatial regulation of CAR-T cells using inducible gene switches and external triggers further improves safety and functionality. In addition, promoting T cell homing through chemokine receptor engineering and enhancing manufacturing processes with universal CAR platforms expand therapeutic applicability. These innovations not only address antigen escape and T cell exhaustion but also optimize the efficacy and safety profile of CAR-T cell therapy.

Furthermore, although triple therapy combining IT and TT was initially thought to be promising, it has failed to clearly demonstrate benefit over current treatments.

Cancer/testis antigens (CTAs) are a large family of proteins, many of which are only expressed in cancerous tissue and immune-privileged germline sites. Melanoma-associated antigen A4 (MAGE-A4) is an intracellular CTA expressed in healthy testis and placenta, and in a range of cancers, including esophageal, head and neck, gastric, ovarian, colorectal, lung, endometrial, cervical, bladder, breast and prostate cancers; soft tissue sarcomas; urothelial and hepatocellular carcinomas; osteosarcoma; and melanoma.
