Main Risk Factors Association with Proto-Oncogene Mutations in Colorectal Cancer

Area of Science:

• Oncology
• Genetics
• Epidemiology

Background:

• Colorectal cancer (CRC) etiology involves multiple factors, but their specific impact on cancer genetics remains unclear.
• Understanding the relationship between lifestyle, socioeconomic status (SES), and genetic mutations in CRC is crucial for targeted prevention and treatment.
• KRAS mutations are common in CRC and play a role in signaling pathways, but their link to external factors is not well-defined.

Purpose of the Study:

• To investigate the association between lifestyle, dietary habits, socioeconomic factors, and specific gene mutations in colorectal cancer.
• To explore the potential impact of environmental and behavioral factors on the genetic landscape of sporadic colorectal cancer.

Main Methods:

• A baseline survey collected data on lifestyle, diet, SES, and anthropometrics from 100 confirmed primary sporadic colorectal cancer patients in Northwest Iran.
• Statistical analysis was employed to identify significant associations between patient characteristics and genetic mutations.

Main Results:

• High socioeconomic status (SES) was significantly associated with an increased likelihood of KRAS gene mutation (OR: 3.01).
• Factors such as carbohydrate and alcohol consumption, reduced physical activity, and a sedentary lifestyle were also linked to a higher odds of KRAS mutations.
• The study identified specific lifestyle and SES factors correlating with KRAS mutations in colorectal cancer.

Conclusions:

• While exact mechanisms are not fully elucidated, lifestyle, dietary, and socioeconomic factors appear to influence KRAS gene mutations in colorectal cancer.
• These findings highlight potential targets for intervention and underscore the importance of considering patient background in CRC research.
