Findings identify macrophages and efferocytosis as a key mediator of prostate cancer skeletal metastasis and the bone microenvironment. Specifically, phagocytic macrophages and efferocytosis were found to be upregulated in the blood of patients with metastatic prostate cancer. Moreover, inhibiting phagocytic macrophages with the chemotherapeutic trabectedin reduced efferocytosis and prostate cancer tumor size in murine models. In addition, trabectedin inhibition of macrophages significantly altered macrophages and efferocytosis in the bone microenvironment a common site of prostate cancer metastasis. Trabectedin was further found to reduce bone mass and bone healing.
