Leone A, Martínez-Gonzalez MA, Martin-Gorgojo A, et al. - A nested case-control study was performed with four controls for each case to evaluate the relationship of three complete dietary patterns (Mediterranean, Dietary Approaches to Stop Hypertension [DASH], and Pro-vegetarian dietary pattern) with the risk of basal cell carcinoma (BCC). Using risk set sampling, researchers selected cases and controls from the SUN (Seguimiento Universidad de Navarra) cohort. Cases were patients without skin cancer at baseline who later reported having physician-diagnosed BCC during the follow-up period. They distinguished 101 incident cases of BCC in this cohort. According to results, the Mediterranean and DASH diets may be correlated with a lower risk of BCC, but further study is required. A 72% relative reduction in the odds of BCC was seen with better adherence to the Mediterranean diet (highest compared with lowest quintile), while a 68% RR reduction was linked to the DASH diet. A lower risk of BCC was related to higher fruit consumption and low-fat dairy products.
