However, few prospective studies have examined the association between plasma inflammatory markers and pancreatic cancer risk. Therefore, we investigated the association of prediagnostic circulating C-reactive protein (CRP), interleukin-6 (IL-6), and TNF-alpha receptor II (TNF-alpha R2) with subsequent pancreatic cancer risk in a prospective, nested case-control study of 470 cases and 1,094 controls from Health Professionals Follow-up Study, Nurses' Health Study, Physicians' Health Study, Women's Health Initiative, and Women's Health Study. The median follow-up time of cases was 7.2 years (range 1-26 years). No association was observed between plasma CRP, IL-6, and TNF-alpha R2 and the risk of pancreatic cancer. Comparing extreme quintiles, the multivariate ORs were 1.10 [95% confidence interval (CI), 0.74-1.63; P-trend = 0.81] for CRP, 1.19 (95% CI, 0.81-1.76; P-trend = 0.08) for IL-6, and 0.88 (95% CI, 0.58-1.33; P-trend = 0.57) for TNF-alpha R2. In conclusion, prediagnostic levels of circulating CRP, IL-6, and TNF-alpha R2 were not associated with the risk of pancreatic cancer, suggesting that systemic inflammation as measured by circulating inflammatory factors is unlikely to play a major role in the development of pancreatic cancer.en-USJournal Article2019-09-0510.1158/1055-9965.EPI-12-1458
