TLDR
Comparing the outcomes from three prospective multicenter studies investigating the use of CTC to monitor patients undergoing treatment for metastatic breast, colorectal, or prostate cancer is compared and the CTC definition used in these studies is reviewed.
Abstract
The increasing number of treatment options for patients with metastatic carcinomas has created a concomitant need for new methods to monitor their use. Ideally, these modalities would be noninvasive, be independent of treatment, and provide quantitative real-time analysis of tumor activity in a variety of carcinomas. Assessment of circulating tumor cells (CTCs) shed into the blood during metastasis may satisfy this need. We developed the CellSearch System to enumerate CTC from 7.5 mL of venous blood. In this review we compare the outcomes from three prospective multicenter studies investigating the use of CTC to monitor patients undergoing treatment for metastatic breast (MBC), colorectal (MCRC), or prostate cancer (MPC) and review the CTC definition used in these studies. Evaluation of CTC at anytime during the course of disease allows assessment of patient prognosis and is predictive of overall survival.

A size amplified immune magnetic microbeads strategy in the rapid detection of circulating tumor cells

TL;DR: Using anti-EpCAM antibody modified magnetic microbeads allowed us to simultaneously apply size-amplification and magnetic labelling of CTCs to the capture and purification of C TCs by membrane filtration and immune-magnetic separation.

Circulating tumor cells in head and neck cancer: clinical impact in diagnosis and follow-up.

TL;DR: The detection of tumor cells, which circulate in the blood of cancer patients, known as circulating tumor cells and those that can be found in the bone marrow, called disseminated tumor cells (DTC) provides a diagnostic source especially for those patients at high risk of locoregional recurrence or distant failure.

Circulating Tumor Cells and Implications of the Epithelial-to-Mesenchymal Transition.

TL;DR: This chapter will review the process of EMT and its contribution to metastasis; discusses current and future clinical applications of CTCs; and describes both traditional and novel methods for CTC enrichment, detection, and characterization with a specific focus on C TCs with an EMT phenotype.

Analysis of circulating tumor cells from lung cancer patients with multiple biomarkers using high-performance size-based microfluidic chip.

TL;DR: The development of the size-based microfluidic device for efficient capture of CTCs will enable detailed characterization of their biological properties and values in cancer diagnosis and could provide more information about metastasis in patients than only usage of epithelial marker.

The pathogenesis of cancer metastasis: the 'seed and soil' hypothesis revisited

TL;DR: It is now known that the potential of a tumour cell to metastasize depends on its interactions with the homeostatic factors that promote tumour-cell growth, survival, angiogenesis, invasion and metastasis.

Isolation of rare circulating tumour cells in cancer patients by microchip technology.

TL;DR: The CTC-chip successfully identified CTCs in the peripheral blood of patients with metastatic lung, prostate, pancreatic, breast and colon cancer in 115 of 116 samples, with a range of 5–1,281CTCs per ml and approximately 50% purity.

Tumor cells circulate in the peripheral blood of all major carcinomas but not in healthy subjects or patients with nonmalignant diseases.

TL;DR: The CellSearch system can be standardized across multiple laboratories and may be used to determine the clinical utility of CTCs, which are extremely rare in healthy subjects and patients with nonmalignant diseases but present in various metastatic carcinomas with a wide range of frequencies.
