Colorectal Cancer Screening Methods and Molecular Markers for Early Detection

Area of Science:

• Oncology
• Gastroenterology
• Molecular Diagnostics

Background:

• Colorectal cancer (CRC) is a prevalent digestive tract malignancy.
• CRC progresses through stages from benign polyps to invasive carcinoma and metastasis.
• Early detection is crucial for improving CRC patient outcomes.

Purpose of the Study:

• To review novel routine screening and diagnostic methods for colorectal cancer.
• To identify reliable molecular markers for the early diagnosis of CRC.

Main Methods:

• Review of current literature on CRC screening and diagnostics.
• Analysis of emerging technologies including Endoscopy, CT colonoscopy, SEPT9 methylation assay, and Fecal tests.
• Evaluation of molecular markers for early CRC detection.

Main Results:

• Various screening modalities like Endoscopy and CT colonoscopy offer visual detection.
• Molecular assays such as SEPT9 methylation and fecal tests provide non-invasive detection avenues.
• Identification of promising molecular markers for enhanced early CRC diagnosis.

Conclusions:

• Novel screening and diagnostic methods show promise for earlier colorectal cancer detection.
• Molecular markers are key to improving the sensitivity and specificity of early CRC diagnosis.
• Continued research into these methods can significantly impact CRC management and patient survival.
