The limited treatment options for triple-negative breast cancer with brain metastasis (TNBC-BM) have left the door of further drug development for these patients wide open. Although immunotherapy via monoclonal antibodies has shown some promising results in several cancers including TNBC, it cannot be considered the most effective treatment for brain metastasis. This is due to the protective role of the blood-brain barrier (BBB) which limits the entrance of most drugs, especially the bulky ones such as antibodies, to the brain. For a drug to traverse the BBB via passive diffusion, various physicochemical properties should be considered. Since natural medicine has been a key inspiration for the development of the majority of current medicines, in this paper, we review several naturally-derived molecules which have the potential for immunotherapy via blocking the interaction of programmed cell death protein-1 (PD-1) and its ligand, PD-L1. The mechanism of action, physicochemical properties and pharmacokinetics of these molecules and their theoretical potential to be used for the treatment of TNBC-BM are discussed.

Background And Objective: Sacituzumab govitecan, an anti-trophoblast cell surface antigen 2 (TROP2) antibody-drug conjugate, has been approved by both the US Food and Drug Administration and European Medicines Agency for patients with metastatic triple-negative breast cancer who have received two or more prior systemic therapies, including at least one of them for advanced disease. Although TROP2 evaluation is not required for patient selection, survival data from the ASCENT trial show improved response rates in patients with high TROP2 expression by immunohistochemistry. However, there is no standardized testing assay for these patients.

Purpose: This large-scale study presents the clinicopathological characteristics and cumulative incidence of contralateral breast cancer (CBC) in Japanese BRCA1/2 pathogenic variant carriers, including cases diagnosed after the implementation of national insurance coverage.
Methods: We analyzed 2949 breast cancer cases from the registry database of the Japanese Organization of Hereditary Breast and Ovarian Cancer.
Results: BRCA1 carriers predominantly developed triple-negative breast cancer, whereas BRCA2 carriers more frequently developed luminal-type tumors, with a younger age of onset observed in BRCA1 carriers.

The development of multifunctional nanoplatforms capable of drug delivery and real-time cellular imaging remains a key challenge in cancer theranostics. Herein, we report the development of a casein-protected maleic acid-derived nitrogen-doped carbon dot-based luminescent nanoplatform (MNCD@Cas NPs) for efficient delivery of the anticancer drug doxorubicin hydrochloride (DOX) to triple-negative breast cancer cells. Synthesized via a facile two-step method, the MNCD@Cas NPs exhibit bright blue fluorescence (λ = 390 nm), high water dispersibility, excellent colloidal stability, and substantial DOX loading capacity (∼84%) driven by electrostatic interactions.

Heat shock protein 70 (HSP70) represents a critical barrier to effective mild-temperature photothermal therapy (MPTT), limiting its clinical utility in aggressive cancers like triple-negative breast cancer (TNBC). While small interfering RNA (siRNA)-mediated HSP70 suppression offers a promising solution, optimal timing for this therapeutic combination remains unexplored. Here, it is demonstrated that precisely timed administration significantly enhances MPTT efficacy through systematic temporal characterization of HSP70 expression dynamics.
