Comprehensive evaluation and progress of colorectal cancer screening methods

Area of Science:

• Oncology
• Public Health
• Preventive Medicine

Background:

• Colorectal cancer (CRC) progresses from polyps to adenomas and then to invasive cancer.
• CRC screening is crucial for interrupting disease progression, reducing morbidity and mortality.
• Widespread screening facilitates early diagnosis and treatment, lessening economic burdens.

Purpose of the Study:

• To systematically review and evaluate existing colorectal cancer (CRC) screening methodologies.
• To provide critical insights for clinical decision-making in selecting optimal CRC screening strategies.
• To identify efficient and economical screening methods for widespread dissemination and minimized missed diagnoses.

Main Methods:

• Systematic literature review of current evidence on CRC screening methodologies.
• Evaluation of existing CRC screening techniques based on efficiency, economy, and diagnostic accuracy.
• Synthesis of findings to inform clinical practice and policy.

Main Results:

• Current CRC screening methods vary in efficiency, cost-effectiveness, and detection rates.
• The review identifies strengths and limitations of different screening approaches.
• Evidence supports the importance of accessible and economical screening for population-level impact.

Conclusions:

• Optimizing CRC screening strategy selection is key to improving early diagnosis and reducing cancer burden.
• Further research is needed to develop and validate highly efficient and economical screening tools.
• Informed clinical decision-making based on robust evidence can enhance the effectiveness of CRC screening programs.
