Serum IL-17 levels can be diagnostic for gastric cancer.

Purpose: Gastric cancer (GC) is one of the most common malignancies worldwide. Although it has been strongly associated with immunopathology, IL-17 also has an important role in host defense so this makes it more important in GC, which is a microorganism-related cancer. The aim of this study was to determine the clinical significance of the serum levels of IL-17 in GC patients.
