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).
