Multimodal Immune Characterization of RAre Soft Tissue Sarcoma - MIRAS Project From SARRA (SARcome RAre) Project of the French Sarcoma Group

Summary

This trial is a translational, open-label, multi-sites, prospective and retrospective cohort study of 500 patients aimed at clinical and biological characterization of sarcoma of rare subtype. 400 patients will be included in this prospective cohort study; they will be identified in the investigating centers in the context of either routine care or a clinical study protocol. Retrospective cases of patients (100 cases in total) will be identified in all centers through the GSF/GETO clinical databases already setted up (including the clinical base Conticabase).

   * Desmoplastic Small Round Cell Tumours (DSRCT)
   * Malignant Solitary Fibrous Tumours (mSFT)
   * Alveolar Soft Part Sarcoma (ASPS)

   * Sclerosing Epithelioid Fibrosarcoma (SEF).
3. Localized/locally advanced or metastatic disease.
4. In case of localized disease, treatment must not have been yet initiated before inclusion (except surgical excision).
5. In case of metastatic disease, project of new line of systemic treatment must have been decided before inclusion.
