Colorectal cancer and smoking,


We also genotyped females and 62 males, who formed the control group.

Genotyping results were related to environmental risk factors, smoking habit and diet. A significantly increased risk for CRC was observed in females colorectal cancer and smoking males with high daily fried red meat intake, carriers of the ArgGln OR 2.

Conclusions: In Romanians, the association between the mutated genotypes and environmental risk factors modulates the risk for sporadic CRC. Smoking in association with the ArgGln-XRCC1 genetic variation influences the early onset of sporadic colorectal cancer in females.

Rezumat Introducere: Variațiile genetice, cum ar fi cele care influențează sistemele de reparare a defectelor de replicare a ADN, pot reprezenta factori de susceptibilitate în cancerul colorectal sporadic CCR ca urmare a interacțiunii cu factori de mediu.

Am determinat de asemenea, genotipurile pentru femei și 62 bărbațicare au format grupul de control. Rezultatele au fost analizate din punct de vedere al relației cu factorii de risc de mediu, fumatul și dieta. Rezultate: Bărbații fumători purtători ai variațiilor genetice ArgGln, Colorectal cancer and smoking, MetThr au avut un risc semnificativ crescut de 4. Un risc semnificativ crescut de a dezvolta cancer colorectal sporadic a fost observat în cazul femeilor și bărbaților cu o dietă bogată în carne roșie prăjită purtători ai variațiilor genetice ArgGln OR 2.

Femeile a căror dietă a inclus cantități mari de carne roșie prăjită au avut un risc semnificativ crescut de a dezvolta timpuriu cancer colorectal sporadic dacă au fost purtătoare a variațiilor genetice ArgGln-XRCC1 OR 5.

Although the causes of this disease are not entirely understood, it is known that several factors influence its occurrence. Risk factors for colorectal cancer include age, family history of colon polyps, inflammatory bowel disease and hereditary syndromes, smoking, obesity, sedentarism, alcohol consumption. Evidence is mounting that detecting this risk factors is a eficient way of selecting persons at high risk for colon cancer, that should undergo the screening mesures.

Concluzii: În cazul populației de origine română, asocierea genotipurilor mutante cu factori de mediu modulează riscul pentru CCR sporadic. La femei, fumatul în asociere cu variația genetică ArgGln-XRCC1 influențează debutul timpuriu al cancerului colorectal sporadic.
