Comprehensive and Integrated Genomic Characterization of Adult Soft Tissue Sarcomas

Cell: Volume 171, Issue 4, p950-965



Sarcomas are a broad family of mesenchymal malignancies exhibiting remarkable histologic diversity. We describe the multi-platform molecular landscape of 206 adult soft tissue sarcomas representing 6 major types. Along with novel insights into the biology of individual sarcoma types, we report three overarching findings: 1) unlike most epithelial malignancies, these sarcomas (excepting synovial sarcoma) are characterized predominantly by copy number changes, with low mutational loads and only a few genes (TP53, ATRX, RB1) highly recurrently mutated across sarcoma types, 2) within sarcoma types, genomic and regulomic diversity of driver pathways defines molecular subtypes associated with patient outcome, and 3) the immune microenvironment, inferred from DNA methylation and mRNA profiles, associates with outcome and may inform clinical trials of immune checkpoint inhibitors. Overall, this large-scale analysis reveals previously unappreciated sarcoma type-specific changes in copy number, methylation, RNA, and protein, providing insights into refining sarcoma therapy and relationships to other cancer types.

Note: To download these 'controlled-access' MAF files, you will need a) the command-line GDC Data Transfer Tool and b) an authentication token file. The token file can be downloaded from the GDC Portal by logging in and clicking on your username, as described here. Next, on the command-line, run the following command in th e directory where the tool is located: ./gdc-client download -t (see Downloading Controlled-Access Data).
