The Therapeutic Potential of Targeting Tumor Microenvironment in Breast Cancer: Rational Strategies and Recent Progress.

The tumor microenvironment (TME) is cellular environment in addition to harboring carcinoma cells, consists of different components (e.g., blood vessels, immune cells, fibroblasts, bone marrow-derived inflammatory cells, lymphocytes, signaling molecules, and the extracellular matrix) that have an essential role on drug activity and efficacy. There is growing body of evidence showing its involvement in the progression and metastasis of different cancers, including breast cancer (BC). These observations provide a proof of concept of targeting TME compartments as a novel potential therapeutic approach in treatment of this malignancy, which is the main interested for current review.
