Trabectedin

Tumor-associated macrophages (TAMs) and other myeloid cells that infiltrate neoplastic lesions promote tumor progression and are associated with poor patient prognosis. We have recently demonstrated that trabectedin, a licensed and commercially available anticancer agent, is selectively cytotoxic for TAMs and their circulating precursors (monocytes). The macrophage-depleting effect of trabectedin is a key component of its antitumor activity.
