Analyse zirkulierender Tumormarker im Blut (ALCINA2)

5. November 2026 aktualisiert von: Institut du Cancer de Montpellier - Val d'Aurelle

The circulating tumoral biomarkers in the blood are the object of numerous researches for several decades. The potential clinical interests of these circulating biomarkers are diagnostic, prognostic, predictive of the efficiency of targeted therapies (according to the mutational profile of the cancer), and could allow the study of the mechanisms of resistance under process. In the multiplicity of these blood potential biomarkers joins a permanent evolution of the technological means used to detect them/to quantify, as well as to estimate their clinical utility.

Detaillierte Beschreibung

The new major challenge in the research concerns the circulating biomarkers, which aim at replacing the molecular analyses on tumour tissue obtained by biopsy (for example the search for somatic mutations of cancer) by a simple blood test (liquid biopsy). The other current important challenge is to have an idea of the interest to analyse the kinetics of blood markers, in particular in answer to a clinical "event", either through the chemotherapy, a biopsy and / or surgery. There is almost no data in the literature on this aspect. It is very likely that the liberation in the blood of the blood tumoral markers is strongly dependent on medical interventions on the tumour.

The study ALCINA 2 rests exactly on the principle of small cohorts, which correspond each to a clinical situation and/or a technique of different implemented detection, so as to generate data of feasibility and proof of concept. In case of success, statistical hypotheses will be necessary for the implementation of wider studies (being then the object of a specific approval by competent authorities).
