Cancer-associated fibroblasts orchestrate pancreatic adeno- carcinoma (PDA) aggressiveness. We show that the Food and Drug Administration–approved somatostatin analog SOM230 inhibits metastasis in murine PDA models by acting through its receptor sst1 to disrupt the cancer-associated fibroblast production of colony stimulating factor 1, a prometastatic and macrophage-attracting chemokine whose stromal expression is associated with PDA aggressiveness.
