A New Risk-Scoring System for Colorectal Cancer and Polyp Screening by Turkish Colorectal Cancer and Polyp Study...

Area of Science:

• Oncology
• Gastroenterology
• Preventive Medicine

Background:

• Colorectal cancer is a leading global cancer diagnosis.
• Early detection of colon polyps and cancer significantly reduces mortality.
• Effective screening methods are crucial for timely diagnosis.

Purpose of the Study:

• To develop a simple, effective, and reliable scoring system for detecting colon polyps and colorectal cancer.
• To identify key risk factors for adenomatous polyp development.

Main Methods:

• Prospective study involving 6508 participants aged 18+ across 16 centers.
• Colonoscopy screening was performed.
• Data collected included demographics, lifestyle factors, and polyp characteristics.

Main Results:

• Independent risk factors for adenomatous polyps identified: age, male gender, obesity, smoking, and family history.
• The developed scoring system demonstrated 81% sensitivity and 40% specificity for adenomatous polyp detection (score ≥ 4).
• For colorectal cancer detection (score ≥ 4), sensitivity was 96% and specificity was 39%.

Conclusions:

• The study recommends initiating colorectal cancer screening for individuals under 50.
• Individuals with a score of 4 or higher should be prioritized for colorectal cancer screening.
• The developed scoring system offers a valuable tool for risk stratification in colorectal cancer screening.
