Characterization of anti-cancer therapy-induced microvascular dysfunction in breast cancer patients with proof-of-concept of targeted intervention.
Background: Cardiotoxicity is a major complication of anti-cancer therapy (CTx); yet, the impact of CTx on the human microcirculation is not well defined. This study evaluated the impact of CTx on microvascular function in breast cancer patients.
Methods: Endothelial function and angiogenic potential were assessed in arterioles and adipose biopsies obtained from breast cancer patients before, during, and after CTx (longitudinal and cross-sectional) and in healthy arterioles exposed to doxorubicin (Dox), trastuzumab (TZM), or paclitaxel (PTX) ex vivo. Conditioned media containing VEGF-B protein was used to test feasibility of a targeted intervention.
Results: Patients treated with Dox and/or TZM in vivo developed profound microvascular endothelial dysfunction that persisted for ≥9 months after treatment cessation. Angiogenic potential was reduced during CTx and recovered within one month after cessation. Gene expression related to angiogenesis and inflammation changed over the course of clinical treatment. Isolated adipose arterioles from healthy donors developed endothelial dysfunction when exposed to Dox or TZM ex vivo. In contrast, paclitaxel (PTX), which poses minimal cardiovascular risk, had no impact on vasomotor function. Ex vivo exposure to Dox or PTX suppressed angiogenic potential, whereas TZM had no effect. Treatment with VEGF-B protein preserved endothelial function in healthy arterioles exposed to Dox or TZM ex vivo.
Conclusion: Breast cancer patients undergoing treatment with Dox and/or TZM develop prolonged microvascular endothelial dysfunction that is recapitulated in healthy arterioles exposed to Dox or TZM ex vivo. Targeted intervention with VEGF-B protects against direct Dox- or TZM-induced vascular toxicity in human arterioles ex vivo.

JCI Insight is a Gold Open Access journal with a 2022 Impact Factor of 8.0. It publishes high-quality studies in various biomedical specialties, such as autoimmunity, gastroenterology, immunology, metabolism, nephrology, neuroscience, oncology, pulmonology, and vascular biology. The journal focuses on clinically relevant basic and translational research that contributes to the understanding of disease biology and treatment. JCI Insight is self-published by the American Society for Clinical Investigation (ASCI), a nonprofit honor organization of physician-scientists founded in 1908, and it helps fulfill the ASCI's mission to advance medical science through the publication of clinically relevant research reports.
