Nutrient intake patterns in gastric and colorectal cancers

Area of Science:

• Oncology
• Nutritional Epidemiology
• Gastroenterology

Background:

• Dietary factors are crucial in the etiology of gastric and colorectal cancers.
• Understanding specific dietary risk patterns is essential for targeted prevention strategies.

Purpose of the Study:

• To investigate and compare dietary risk patterns for gastric and colorectal cancers.
• To utilize a consistent methodological approach across both cancer types.

Main Methods:

• A parallel, hospital-based case-control study design was employed.
• Histopathologically confirmed cases of colorectal cancer (n=180) and stomach cancer (n=80) were recruited from the University Hospital in Cracow.

Main Results:

• High carbohydrate intake correlated with increased colorectal cancer risk (OR=2.45).
• For stomach cancer, moderate carbohydrate intake (OR=4.29) and high intake (OR=8.73) significantly increased risk.
• Fat intake patterns differed; medium fat intake (OR=1.96) and intake >83 g/day (OR=2.20) increased colorectal cancer risk, while higher fat consumption showed no association with stomach cancer risk.
• Retinol, carotene, and vitamin C showed protective effects in colorectal cancer; carotene and vitamin E were inversely correlated with stomach cancer.

Conclusions:

• Dietary carbohydrate and fat intake present distinct risk profiles for gastric versus colorectal cancers.
• Specific micronutrients like vitamins C and E, retinol, and carotene may play differential roles in the risk of these cancers.
