Dr. Anton Bilchik, surgical oncologist and chief of medicine and Director of the Gastrointestinal and Hepatobiliary Program at Providence Saint John’s Cancer Institute in Santa Monica, CA, told Medical News Today:
“Pancreas cancer is one of the most chemotherapy-resistant tumors. One of the reasons is that it is typically surrounded by a thickened scar (fibrosis) which makes chemotherapy penetration difficult. Another reason is that the majority of patients with pancreas cancer present with advanced disease at a point where it has already spread.”
