E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Translational sub-study
SFT cohort:
- To perform a central pathologic review (diagnosis confirmation) of paraffin-embedded tumor blocks for each recruited patient with SFT, including (exploratory) STAT6 immunohistochemistry.
- To evaluate the serum profile of serum cytokine markers as indicator of response to pazopanib. The Luminex technology will be employed for the analysis of 12 cytokines [VEGF-A, PlGF-1, SDF-1 alpha (CXCL12), TNF alpha, IL-8, IL-6, PDGF–beta, HGF, E-Selectine, ICAM1, MMP-9 and FGFb].
- To evaluate the profile of angiogenic markers in the primary tumor. Microvessel density (MVD) and VEGF/PDGF pathways will be evaluated by IHQ expression as well as their correlation with prognosis and their role as predictive factors to treatment with pazopanib (response, PFS and OS).
- To evaluate pharmacodynamic markers (MVD, VEGF/PDGF) only in patients with paired samples (in the biopsies taken after treatment).
EMC cohort:
- To perform a central pathologic review (diagnosis confirmation) of paraffin-embedded tumor blocks for each recruited patient with EMC, including FISH analysis and/or RT-PCR NR4A3 and its partners (EWSR1, TAF15).
- To evaluate the expression and activation profile of angiogenic targets (VEGFR, PDGFR, RET, MCSR1) in the primary tumor by immunohistochemistry, pRTK array and IP/WB respectively. |
Etude translationnelle
Cohorte SFT :
-Réaliser une relecture anatomopathologique centralisée sur blocs de tumeur archivés inclus en paraffine (confirmation diagnostique) pour tout patient porteur d’une SFT, incluant l’immunomarquage de STAT6 (exploratoire),
-Evaluer le profil de cytokines comme marqueurs sériques de réponse au pazopanib. La technologie Luminex sera utilisée pour l’analyse de 12 cytokines : VEGF-A, PIGF-1, SDF-1 alpha (CXCL12), TNF alpha, IL-8, IL-6, PDGF-Beta, HGF, E-selectin, ICAM1, MMP-9 and FGFb.
-Evaluer le profil des marqueurs de l’angiogénèse dans la tumeur primaire. La densité micro vasculaire et les voies VEGF/PDGF seront étudiées par IHC de même que leur corrélation avec des facteurs pronostiques ou prédictifs de réponse au pazopanib (réponse, SSP et SG).
-Evaluer la pharmacodynamique de marqueurs (MVD, VEGF/PDGF) uniquement chez les patients disposant d’échantillons appariés (matériel disponible avant et après traitement).
Cohorte EMC :
-Réaliser une relecture anatomopathologique centralisée sur blocs de tumeurs archivés inclus en paraffine (confirmation diagnostique) pour tout patient porteur d’un EMC, incluant l’analyse de NR4A3 et de ses partenaires (EWSR1, TAF15) en FISH et/ou en RT-PCR (exploratoire),
-Evaluer l’expression et l’activation de cibles impliquées dans l’angiogénèse (VEGFR, PDGFR, RET, MCSR&) dans la tumeur primaire, en utilisant respectivement l’IHC, pRTK array et IP/WB
