Serum uric acid is a risk factor for gallbladder cancer in men and has a strong effect on pancreatic cancer in women. It has also been shown that elevated intracellular serum uric acid can induce an inflammatory stress response, which may promote its transformation, while elevated extracellular serum uric acidy further stimulate tumor cell proliferation, migration, and survival, and promote the development of highly aggressive cancer. In this study, the changes of serum uric acid before and after surgery was used as a prognostic marker for the survival of pancreatic cancer patients.
