National Clinical and Biological Sarcoma Database : An Initiative of the French Sarcoma Group

Study Overview
=================
Brief Summary
-----------------
The BCB SARCOMES database is a clinical and biological national database dedicated to sarcoma that contains 3 main databases with specific aims: the first is the pathology database (French expert network dedicated to the management of bone sarcomas [RESOS] / French expert network dedicated to the pathology of sarcomas [RREPS]), dedicated to systematic review of mesenchymal tumor diagnostics nationwide; the second is clinical (RESOS / French expert clinical network for sarcomas [NETSARC]), collecting multidisciplinary tumor boards (MDTB) data of patients nationwide, and the third (CONTICABASE / BONE / GIST) is dedicated to collecting patients longitudinal/follow up data, with a focus on treatments of every events, and a catalogue of associated samples. Primary objectives of BCB-SARCOMES are the following: description of the patterns of care and treatment outcomes, assessment of the prognostic factors of patients' outcomes. With the financial support of the French National Cancer Institute [Institut National du cancer [INCa]).

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
