[Sarcoma: tumour banks and evolution of diagnostic procedures]

Regional tumour banks are nowadays an important tool for the management of patients with a sarcoma. Centralized databases with information on frozen or paraffin-embedded tumour samples are necessary tools for clinical and biological research projects for rare tumours and particularly sarcomas. Diagnostic procedures have evolved during the last years with a multidisciplinary management of patients by a national and structured network specialized in sarcomas, a common use of core needle biopsies, a daily use of immunohistochemistry and molecular analyses and the implementation of standardized and structured reports.
