BACKGROUND: Gastric cancer is the fifth most common cancer worldwide and the fifth leading cause of cancer-related death. Its poor prognosis is primarily due to a late diagnosis and a lack of effective treatments for advanced disease.
METHODS: We examined a patient cohort comprising 239 individuals who underwent surgery for histologically verified gastric adenocarcinoma in the Department of Surgery at Helsinki University Hospital between 2000 and 2009, comparing them to 48 healthy controls. We measured the serum protein concentrations for 48 different cytokines and growth factors using Bio-Rad's premixed Bio-Plex Pro Human Cytokine 27-plex and 21-plex assay kits.
RESULTS: Five serum biomarkers were identified as indicative of gastric cancer. Cancer patients had higher serum levels of CLEC11A [odds ratio (OR) 1.16, 95% confidence interval (CI) 1.08-1.26, p = 0.004], IL-7 (OR 2.73, 95% CI 1.48-5.04, p = 0.014), IL-8 (OR 6.30, 95% CI 2.23-20.0, p = 0.017), and IL-13 (OR 2.67, 95% CI 1.33-5.37, p = 0.041). The CCL5 levels were lower in cancer patients compared with controls (OR 0.30, 95% CI 0.14-0.60, p = 0.014).
CONCLUSIONS: In a large cohort of 239 patients, we identified five biomarkers for which serum levels associated with gastric cancer: CCL5, CLEC11A, IL-7, IL-8, and IL-13. High serum levels of CLEC11A have not previously been associated with gastric cancer. Our results provide new support to further explore the effect of these inflammatory molecules and the role they play in gastric cancer. This may help identify novel noninvasive diagnostic methods as well as potential new druggable targets.
