Abstract:
Traditional methods for colorectal cancer (CRC) screening have reduced rates of malignancy and death; however, low compliance and morbidities associated with invasive techniques have encouraged efforts for establishing equally effective, less invasive novel screening approaches. We review the current state of novel screening approaches in CRC to include CT colonography, fecal DNA, DNA methylation, micro-RNA, and protein and molecular markers.
Insights
Novel colorectal cancer (CRC) screening methods are being developed to improve patient compliance and reduce risks. This review covers emerging techniques like CT colonography and various molecular markers for CRC detection.
Area of Science:
- Oncology
- Gastroenterology
- Medical Diagnostics
Background:
- Traditional colorectal cancer (CRC) screening methods have limitations including low patient compliance and potential morbidities.
- There is a growing need for non-invasive and effective screening tools for early detection of colorectal cancer.
Purpose of the Study:
- To review the current advancements in novel screening approaches for colorectal cancer (CRC).
- To evaluate emerging technologies that offer alternatives to traditional CRC screening methods.
Main Methods:
- Literature review of current research on novel CRC screening techniques.
- Analysis of emerging diagnostic markers and imaging modalities for colorectal cancer.
Main Results:
- CT colonography shows promise as a less invasive imaging technique.
- Fecal DNA, DNA methylation, micro-RNA, and protein/molecular markers represent promising avenues for non-invasive CRC detection.
Conclusions:
- Novel screening approaches for colorectal cancer are evolving, offering potential improvements in compliance and safety.
- Further research and validation are necessary to establish the efficacy of these new CRC screening strategies.
