RT Journal Article T1 Flavonoids and the Risk of Gastric Cancer: An Exploratory Case-Control Study in the MCC-Spain Study A1 Vitelli Storelli, Facundo A1 Capelo Álvarez, Rocío A1 Martín, Vicente AB Several epidemiological studies have investigated the association between the dietaryflavonoid intake and gastric cancer (GC) risk; however, the results remain inconclusive. Investigatingthe relationship between the different classes of flavonoids and the histological types and origin ofGC can be of interest to the research community. We used data from a population-based multi-casecontrol study (MCC-Spain) obtained from 12 different regions of Spain. 2700 controls and 329 GCcases were included in this study. Odds ratios (ORs) were calculated using the mixed effects logisticregression considering quartiles of flavonoid intakes and log2. Flavonoid intake was associatedwith a lower GC risk (ORlog2 = 0.76; 95% CI = 0.65–0.89; ORq4vsq1 = 0.60; 95%CI = 0.40–0.89;ptrend = 0.007). Inverse and statistically significant associations were observed with anthocyanidins,chalcones, dihydroflavonols and flavan-3-ols. The isoflavanoid intake was positively associated withhigher cancer risk, but without reaching a statistical significance. In general, no differences wereobserved in the GC risk according to the location and histological type. The flavonoid intake seemsto be a protective factor against GC within the MCC-study. This effect may vary depending on theflavonoid class but not by the histological type and location of the tumor. Broader studies with largersample size and greater geographical variability are necessary.
