Ever-regular use associated with lowered risk, with 8 percent decrease for each cumulative year of use
TUESDAY, Dec. 20, 2016 (HealthDay News) — Regular aspirin use is associated with reduced risk of pancreatic cancer in a Chinese cohort, according to a study published online Dec. 20 in Cancer Epidemiology, Biomarkers & Prevention.
Harvey A. Risch, M.D., Ph.D., from the Yale School of Public Health in New Haven, Conn., and colleagues conducted a population-based study involving 761 case and 794 control subjects, frequency matched on sex and age during 2006 to 2011 in China. Participants were asked about aspirin use.
The researchers observed a correlation for ever-regular use of aspirin with lower risk of pancreatic cancer (odds ratio, 0.54). For each cumulative year of use the risk decreased 8 percent (odds ratiotrend, 0.92). For any aspirin type and for low-dose aspirin, the odds ratios for ever-regular use decreased with increasingly more recent mid-study year across 18 other published studies of this association.
“In conclusion, we observed a significant inverse relationship between aspirin use and risk of pancreatic cancer in a large representative sample of Chinese individuals,” the authors write. “The pattern of risk reduction was very similar to that seen in other recent studies in the United States and elsewhere.”
