Metastasis

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Cancer Stem Cells and Tumor Maintenance

Cancer Stem Cells and Tumor Maintenance

Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

Area of Science:

Oncology
Molecular Biology
Clinical Diagnostics

Background:

Circulating tumor cells (CTCs) are epithelial cells found in blood, with demonstrated prognostic and predictive value in metastatic cancer.
Current methods like CellSearch® monitor CTC counts in colorectal, breast, and prostate cancer, where rising counts predict poor outcomes.
The clinical utility of monitoring CTC counts and the optimal management strategy when counts increase during therapy remain debated.

Purpose of the Study:

To propose an integrated approach combining CTC counts with molecular characterization.
To enhance the translation of biologic information from CTCs into clinical practice.
To address the controversy surrounding the clinical utility of CTC monitoring.

Main Methods:

Review of current literature on CTC detection and prognostic value.
Discussion of the limitations of CTC count monitoring alone.
Proposal for integrating molecular profiling of CTCs with routine monitoring.

Main Results:

CTC counts, particularly using CellSearch®, are established prognostic markers in specific metastatic cancers.
A rise in CTC count during treatment is linked to poorer patient outcomes.
Molecular characterization of CTCs offers additional biologic insights beyond mere cell counts.

Conclusions:

Integrating CTC counts with their molecular characterization is crucial for improved clinical utility.
This combined approach can better inform treatment decisions and patient management strategies.
Further research is needed to fully establish standardized protocols for integrated CTC analysis in clinical settings.
