Extracellular vesicles in colorectal cancer

Area of Science:

• Oncology
• Biochemistry
• Molecular Biology

Background:

• Colorectal cancer (CRC) presents significant global health challenges, particularly in early detection and recurrence monitoring.
• Current screening methods like colonoscopy and fecal tests have limitations, prompting research into less invasive alternatives.
• Extracellular vesicles (EVs) in liquid biopsies are emerging as promising biomarkers due to their molecular cargo reflecting the tumor's status.

Purpose of the Study:

• To review the role of EVs in colorectal cancer initiation and progression.
• To summarize advancements in EV isolation techniques for clinical application.
• To identify potential EV-derived biomarkers for CRC diagnosis, prognosis, and treatment monitoring.

Main Methods:

• Literature review of current research on extracellular vesicles in colorectal cancer.
• Analysis of EV cargo (nucleic acids, proteins) as potential biomarkers.
• Evaluation of EV isolation and detection methodologies.

Main Results:

• EVs play a crucial role in colorectal cancer development and progression.
• Minimally invasive liquid biopsy using EVs offers a viable alternative to traditional screening.
• Specific EV-derived molecules show potential as diagnostic and prognostic biomarkers for CRC.

Conclusions:

• Extracellular vesicles hold significant potential as biomarkers for colorectal cancer management.
• Further research and clinical validation are needed to translate EV-based approaches into routine practice.
• EVs may offer novel therapeutic strategies and improved monitoring for colorectal cancer patients.
