RNA-seq performed on FFPE sarcoma blocks


ABSTRACT: We validated the technological and material transfers of the CINSARC signature. We performed both microarray and RNA-seq analysis and compared prognostic values based on the CINSARC classification. We measure significant metastasis-free survivals with both approaches. Additionally, depending on RNA degradation, transcriptomic analysis from FFPE blocks show similar CINSARC classification.

<h4>Background</h4>Prognosis of metastatic outcome in soft tissue sarcomas is an important clinical challenge since these tumours can be very aggressive (up to 50% of recurring events). A gene expression signature, Complexity INdex in SARComas (CINSARC), has been identified as a better prognostic factor compared to the current international grading system defined by the Fédération Nationale des Centres de Lutte Contre le Cancer. Since CINSARC has been established on frozen tumours analysed by mi  ...[more]
