Synovial Sarcoma: A Clinical Review.

Curr Oncol 2021 May 19;28(3):1909-1920. Epub 2021 May 19.

Department of Surgery, Division of Orthopaedic Surgery, McMaster University, Hamilton, ON L8V 1C3, Canada.

Synovial sarcomas (SS) represent a unique subset of soft tissue sarcomas (STS) and account for 5-10% of all STS. Synovial sarcoma differs from other STS by the relatively young age at diagnosis and clinical presentation. Synovial sarcomas have unique genomic characteristics and are driven by a pathognomonic t(X;18) chromosomal translocation and subsequent formation of the SS18:SSX fusion oncogenes. Read More

Unmasking BCL-2 Addiction in Synovial Sarcoma by Overcoming Low NOXA.

Cancers (Basel) 2021 May 12;13(10). Epub 2021 May 12.

Sarcoma Program, School of Medicine and Massey Cancer Center, Virginia Commonwealth University, Goodwin Research Building, Rm 382, 401 College St. P.O. Box 980037, Richmond, VA 23298, USA.

Synovial sarcoma (SS) is frequently diagnosed in teenagers and young adults and continues to be treated with polychemotherapy with variable success. The SS18-SSX gene fusion is pathognomonic for the disease, and high expression of the anti-apoptotic BCL-2 pathologically supports the diagnosis. As the oncogenic SS18-SSX fusion gene itself is not druggable, BCL-2 inhibitor-based therapies are an appealing therapeutic opportunity. Read More

Genes Chromosomes Cancer 2021 May 14. Epub 2021 May 14.

Department of Pathology, Rigshospitalet, Copenhagen University Hospital, Copenhagen, Denmark.

Undifferentiated sarcomas remain difficult to classify. Despite the remarkable advances in sarcoma classification made by the increased application of RNA sequencing in clinical practice, the unexpected result of a novel gene fusion raises further questions regarding the tumor histogenesis and subclassification. In this study, we present two high grade sarcomas with epithelioid phenotype occurring in the deep-soft tissues (shoulder, thigh) of young adults which based on the non-specific pathologic findings were deemed unclassified and subjected to targeted RNA sequencing for further diagnostic interpretation.

ETV4/5 drive synovial sarcoma through control of the cell cycle and the DUX4 embryonic pathway.

J Clin Invest 2021 May 13. Epub 2021 May 13.

Department of Medicine, Division of Medical Oncology, University of Miami Miller School of Medicine, Miami, United States of America.

Synovial sarcoma is an aggressive malignancy with no effective treatments for patients with metastasis. The synovial sarcoma fusion, SS18-SSX, which recruits the SWI/SNF-BAF chromatin remodeling and polycomb repressive complexes, results in epigenetic activation of FGFR signaling. In genetic FGFR knockout models, culture, and xenograft synovial sarcoma models treated with the FGFR inhibitor BGJ398, we show that FGFR1, FGFR2, and FGFR3 were crucial for tumor growth. Read More

IL-15 mediated expansion of rare durable memory T cells following adoptive cellular therapy.

J Immunother Cancer 2021 May;9(5)

Fred Hutchinson Cancer Research Center, Clinical Research Division, Seattle, WA, USA

Background: Synovial sarcoma (SS) and myxoid/round cell liposarcoma (MRCL) are ideal solid tumors for the development of adoptive cellular therapy (ACT) targeting NY-ESO-1, as a high frequency of tumors homogeneously express this cancer-testes antigen. Data from early phase clinical trials have shown antitumor activity after the adoptive transfer of NY-ESO-1-specific T cells. In these studies, persistence of NY-ESO-1 specific T cells is highly correlated with response to ACT, but patients often continue to have detectable transferred cells in their peripheral blood following progression.
