Palabras clave: Diet colorectal cancer risk Ki-ras

Resumen: BACKGROUND: The diversity of the Mediterranean diet and the heterogeneity of acquired genetic alterations in colorectal cancer (CRC) led us to examine the possible association between dietary factors and mutations, such as Ki-ras mutations, in genes implicated in the pathogenesis of these neoplasms. PATIENTS AND METHODS: The study was based on 246 cases and 296 controls. For the molecular study only 117 patients with Ki-ras tumor expression were included. Dietary patterns were assessed using a semi-quantitative food frequency questionnaire. RESULTS: Patients with Ki-ras mutations in codon 12 (K12) consumed significantly less vitamin A (p=0.02), B1 (p=0.01), D (p=0.02) and iron (p=0.03) than controls, whereas patients without these mutations had similar intakes of these nutrients to controls. The consumption of fiber, folate, vitamin E and potassium was lower in the two subgroups of patients (K12-positive or -negative) than in controls. Mutation in codon 13 was not associated with any nutrient deficit. CONCLUSION: These results support previous findings that certain micronutrients protect against colorectal neoplasia and emphasize the importance of considering the different molecular forms of CRC as etiologically distinct diseases.
