Hábitos alimentarios y riesgo de cancer de piel no melanoma

Abstract

A case-control study was carried out in order to analyze the association between diet and risk of non melanoma skin cancer -basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), with adjustments for demographic, anthropometric and phenotypic characteristics, sunburns history, skin cancer family history, sun-exposure history and skin sensitivity to sun exposure. A full-body skin examination was performed. Dietary data were obtained applying a standardized semi-quantitative questionnaire of consumption frequency. Cases (n=27; age: 65,5±15,1 years) and controls (n=37; age: 63,9±12,3 years) were attended at the same facilities. A decreased risk of BCC and SCC tumors (Adjusted Odd Ratio=0.10; IC 95%= 0.02-0.63; p=0.01) was found for high intakes of green leafy vegetables (more than 40 gr/day). However, results obtained for fruits, cruciferous, vitamin A and carotene-rich vegetables and other vegetables were not statistically significant.
