Current challenges in metastasis: disseminated and circulating tumor cells detection

Area of Science:

• Oncology
• Biomarkers
• Cancer Diagnostics

Background:

• Metastatic dissemination is a primary cause of cancer mortality.
• Detecting disseminated tumor cells (DTCs) and circulating tumor cells (CTCs) in peripheral blood correlates with early metastatic recurrence.
• CTCs originate from primary or metastatic tumors and circulate in the bloodstream.

Purpose of the Study:

• To highlight the significance of detecting rare circulating tumor cells (CTCs).
• To explore the potential of CTCs in early cancer recurrence detection, therapy resistance identification, and outcome prediction.
• To discuss the role of CTCs in monitoring treatment efficacy and guiding therapy selection.

Main Methods:

• Review of various techniques applied for CTC detection and isolation.
• Focus on enrichment methods for CTCs from heterogeneous patient blood samples.
• Integration of standardization for CTC enrichment methods in clinical trials.

Main Results:

• CTC detection provides an objective measure for monitoring cancer progression.
• CTCs can reveal molecular changes and therapy resistance during treatment.
• The presence of CTCs is linked to clinical outcomes and recurrence rates.

Conclusions:

• Advancements in CTC detection methods are crucial for improving clinical applications.
• Standardization of CTC enrichment techniques is essential for reliable clinical trial integration.
• CTC analysis holds significant potential for personalized cancer management and monitoring.
