Risk-based screening for early detection of colorectal cancer: an overview

Area of Science:

• Oncology
• Preventive Medicine
• Public Health

Background:

• Population-based colorectal cancer (CRC) screening reduces incidence and mortality.
• Current screening benefits and harms vary significantly among individuals.
• Low-risk individuals may experience unnecessary burdens, while high-risk individuals might need more intensive screening.

Purpose of the Study:

• To explore the potential of risk-based screening for colorectal cancer (CRC).
• To address the limitations of uniform screening protocols by personalizing screening strategies.
• To evaluate how risk stratification can optimize CRC screening benefits and minimize harms.

Main Methods:

• Risk-based screening utilizes factors like age, sex, race, ethnicity, lifestyle, genetics, and prior screening history.
• Tailoring screening intensity based on individual risk profiles.
• Evaluating potential benefits including cost-effectiveness and resource optimization.

Main Results:

• Risk-based screening may enhance cost-effectiveness and efficient resource allocation.
• It has the potential to reduce unnecessary procedures for low-risk individuals.
• Optimizes the balance of individual benefits and harms in CRC screening.

Conclusions:

• Risk-based screening offers a promising approach to personalize colorectal cancer (CRC) management.
• Challenges remain, including the need for validated risk tools and addressing healthcare capacity.
• Further research is essential to overcome hurdles and fully realize the potential of risk-based CRC screening for improved patient experience and reduced disease burden.
