[Advances in capture methods of circulating tumor cells]

Area of Science:

• Oncology
• Biotechnology
• Medical Diagnostics

Background:

• Circulating tumor cells (CTCs) provide critical genetic and phenotypic information from tumor tissues.
• CTCs are essential biomarkers for liquid biopsy, aiding in early cancer diagnosis, treatment selection, and prognosis evaluation.
• The extremely low concentration of CTCs in blood presents significant challenges for their capture and detection.

Purpose of the Study:

• To review recent advancements in methods for capturing circulating tumor cells (CTCs).
• To analyze the advantages and disadvantages of various CTC capture techniques.
• To discuss future trends in CTC capture technologies for liquid biopsy.

Main Methods:

• Summary of CTC capture methods based on biophysical properties.
• Review of affinity-based CTC capture strategies.
• Discussion of CTC capture using artificial antibodies.

Main Results:

• Evaluation of capture efficiency across different CTC isolation methods.
• Assessment of capture purity and its impact on downstream analysis.
• Analysis of CTC activity maintenance post-capture and release.

Conclusions:

• Recent advances offer improved strategies for CTC capture, addressing low concentrations.
• Understanding the trade-offs in efficiency, purity, and activity is crucial for method selection.
