Allyson Ocean, MD, medical oncologist, attending physician, Gastrointestinal Oncology, Weill Cornell Medicine/New York-Presbyterian Hospital, medical oncologist, The Jay Monahan Center for Gastrointestinal Health, associate professor of medicine, Weill Medical College of Cornell University, discusses emerging anti-stromal agents in pancreatic cancer.

One of the reasons why pancreatic cancer therapies fail is because they can’t penetrate fibroblast-enriched stroma that are devoid of immune cells. We now know from previously reported research that the vitamin D receptor is very important in the stroma.

The activation of the vitamin D receptor relates to the pancreatic stellate cell, which is responsible for the immune cross talk and signaling that happens within pancreatic cancer in the stroma. Research has shown that inhibiting the vitamin D receptor with vitamin D analogs can turn the stellate cell into a less active cell. This can ultimately bring more immune cells into the stroma and allow for better penetration with chemotherapy.
