1Gastroenterology Section, Portland Veterans Administration Medical Center, Oregon 97207, USA.
Colorectal cancer screening for average-risk individuals over 50 can reduce mortality. The optimal screening method and enhancing patient adherence require further research.
Area of Science:
- Gastroenterology
- Oncology
- Preventive Medicine
Background:
- Colorectal cancer (CRC) biology offers opportunities for early detection and prevention.
- Screening asymptomatic, average-risk individuals over 50 can decrease CRC mortality.
- New US Preventive Services Task Force guidelines recommend fecal occult blood tests or sigmoidoscopy.
Purpose of the Study:
- To review various colorectal cancer screening options.
- To examine the downstream effects of screening.
- To review anticipated costs and effectiveness of screening methods.
Main Methods:
- Literature review of colorectal cancer screening modalities.
- Analysis of screening guidelines and recommendations.
- Examination of cost-effectiveness and adherence factors.
Main Results:
- Evidence supports screening for reducing colorectal cancer mortality in average-risk individuals over 50.
- The optimal population screening method remains undetermined.
- Patient compliance is critical for screening program effectiveness.
Conclusions:
- Colorectal cancer screening is effective in reducing mortality.
- Further research is needed to identify the best screening methods and improve patient adherence.
