Toll-like receptor 2 and Toll-like receptor 4 predict favorable prognosis in local pancreatic cancer.

Toll-like receptors play an essential role in our innate immune system and are a focus of interest in contemporary cancer research. Thus far, Toll-like receptors have shown promising prognostic value in carcinomas of the oral cavity, colon, and ovaries, but the prognostic role of Toll-like receptors in pancreatic ductal adenocarcinoma has not been established. We set out to investigate whether Toll-like receptor expression could serve in prognostic evaluation in pancreatic ductal adenocarcinoma, as well.
