To better characterize the TRS patterns compared to other sarcomas.


Retrospective multicenter study of 12,262 patients treated between 01/1980 and 12/2013 in one of 22 French Referral Sarcoma Center and enrolled in the “Conticabase”. Diagnoses were systematically reviewed by expert pathologists and entities classified according to the 2013 WHO Classification.


The median follow-up was 4.9 years (95%-CI: 4.7-5.0). TRS included 13 entities: synovial S (760 cases; 7.4%/5-y OS: 64%), myxoid LPS (436; 4.2%/5-y OS:88%), PNET (205; 2.0%/5-y OS:58%), round cell LPS (183; 1.8%/5-yOS: 70%), alveolar RMS (122; 1.2%/5-yOS: 25%), malignant SFT (86; 0.8%/5-yOS: 77%), clear cell sarcoma (63; 0.6%/5-yOS: 67%), LGFMS (60; 0.6%/5-yOS: 82%), desmoplastic round cell tumor (56, 0.5%/5-y OS: 11%), ESMCS (54; 0.5%/5-yOS:78%), ASPS (48; 0.5%/5-yOS: 66%), EHE (42; 0.4%/5-yOS: 55%), and sclerosing epithelioid fibrosarcoma (28; 0.3%/5-y OS: 70%). All TRS (2,143 cases; 20.8%) are associated with younger age (40.6 versus 60.0; p 


TRS display specific pattern compared to other sarcomas. Second opinion by expert pathologist and use of molecular biology confirmatory test are of major importance to recognize this population and discuss multimodal approach at early stage of the disease.
