Immune-based therapy in mice shows promise against pancreatic cancer

While immune therapy has proven effective in treating certain types of cancer, especially lung cancer and melanoma, tumors of the pancreas remain among the most difficult to treat and, so far, are impervious to immune-based therapies. Now, a new study in mice has shown that immunotherapy against pancreatic cancer can be effective when given in conjunction with drugs that break up the fibrous tissue in these tumors.
