Les enjeux du préanalytique dans l’analyse du transcriptome et du proteome sanguins Application à la recherche clinique: l’expérience du GOELAMS [Stakes of pre-analytical parameters in blood transcriptomic and proteomic analysis. Application to clinical research: the GOELAMS trial]

International audience ; Numerous parameters related to the patients and the conditions of the sample collection can affect the properties of a biological sample. The pre-analytical parameters are especially important to deal with in the setting of multicenter clinical trials. Here, we report the preliminary results of a trial conducted by the cooperative group GOELAMS (Groupe Ouest-Est des Leucémies aiguës et Autres Maladies du Sang) to define the pre-analytical parameters that affect the proteomic analysis of serum samples in patients with B-cell non Hodgkin lymphoma included in clinical trials.
