Les cellules tumorales circulantes : méthodes de détection et intérêt en oncologie (original) (raw)

Revue Francophone des Laboratoires, 2013

Abstract

ABSTRACT For several decades, there is a strong and permanent effort in translational research for the discovery of new oncology biomarker for diagnosis (in particular for an early screening of cancer), prognosis or prediction of treatment efficacy. These biomarkers are analyzed from tissues, cells or biological fluid samples. In this context, there is a growing enthusiasm around the detection of circulating tumor cells (CTC) in the blood of cancer patients since this detection may have a strong diagnostic, prognostic and/or theranostic interest. Numerous direct and indirect methods were developed to detect and characterize the CTC. However, there is a great variability in the sensitivity and the specificity of these methods. Each available method shows certain advantages, but also some disadvantages. The advent of targeted therapies in oncology has suddenly intensified the interest in the CTC field. The detection of genomic alterations in CTC could be associated with a personalized medicine according to the identified mutations. The purpose of this review is to describe the main methods for CTC detection and characterization, and the potential clinical utility of CTC in oncology.
