A non-canonical SWI/SNF complex is a synthetic lethal target in cancers driven by BAF complex perturbation.

Nat Cell Biol 2018 12 5;20(12):1410-1420. Epub 2018 Nov 5.

Department of Pediatric Oncology, Dana-Farber Cancer Institute and Harvard Medical School, Boston, MA, USA.

Mammalian SWI/SNF chromatin remodelling complexes exist in three distinct, final-form assemblies: canonical BAF (cBAF), PBAF and a newly characterized non-canonical complex (ncBAF). However, their complex-specific targeting on chromatin, functions and roles in disease remain largely undefined. Here, we comprehensively mapped complex assemblies on chromatin and found that ncBAF complexes uniquely localize to CTCF sites and promoters. Read More

Calcifying Nested Stromal-Epithelial Tumor of the Liver: An Update and Literature Review.

Arch Pathol Lab Med 2019 Feb 24;143(2):264-268. Epub 2018 Oct 24.

From the Department of Pathology, Yale University School of Medicine, New Haven, Connecticut.

Calcifying nested stromal-epithelial tumor is a rare entity that has gone by a variety of names in the literature: ossifying malignant mixed epithelial and stromal tumor, ossifying stromal-epithelial tumor, and desmoplastic nested spindle cell tumor of the liver. To our knowledge, approximately 38 cases have been reported in the literature. The histogenesis is still largely unknown but histopathologically is characterized by nests of spindle and epithelioid cells in an organoid arrangement surrounded by a prominent dense myofibroblastic stroma with occasional psammomatous calcification and focal heterotopic ossification.

Release of circulating tumor cells and cell-free nucleic acids is an infrequent event in synovial sarcoma: liquid biopsy analysis of 15 patients diagnosed with synovial sarcoma.

Diagn Pathol 2018 Oct 17;13(1):81. Epub 2018 Oct 17.

1st Department of Pathology and Experimental Cancer Research, Semmelweis University, Üllői út 26, Budapest, H-1085, Hungary.

Background: Synovial sarcoma is a rare soft tissue tumor which contains the unique SS18-SSX1, SS18-SSX2 - or, rarely, SS18-SSX4 - fusion transcripts. It is well known that some soft tissue tumors, like Ewing sarcomas and myxoid liposarcomas, can spread via the blood with free circulating tumor cells (CTC); this can be detected by several sensitive molecular biology methods. Here we report a study of fifteen synovial sarcoma patients with varied clinical backgrounds. Read More

Rearrangement and CD99 Expression as Diagnostic Biomarkers for Ewing/PNET Sarcomas in a Moroccan Population.

Dis Markers 2018 18;2018:7971019. Epub 2018 Sep 18.

Pathological Anatomy and Molecular Pathology Department, Hassan II University Hospital of Fez, Morocco.

Ewing sarcoma/primitive neuroectodermal tumor (Ewing/PNET sarcomas or EPS) are a group of round cell tumors. Malignant round cell tumors form a large and diverse group that includes rhabdomyosarcoma, synovial sarcoma, non-Hodgkin's lymphoma, neuroblastoma, hepatoblastoma, Wilm's tumor, desmoplastic small round cell tumor, and other morphologically similar entities. Differential diagnosis of Ewing sarcoma/primitive neuroectodermal tumor (Ewing/PNET sarcomas or EPS) is difficult. Read More

Oral Recombinant Methioninase Combined with Caffeine and Doxorubicin Induced Regression of a Doxorubicin-resistant Synovial Sarcoma in a PDOX Mouse Model.

Anticancer Res 2018 Oct;38(10):5639-5644

AntiCancer, Inc., San Diego, CA, U.S.A.

Background/aim: Synovial sarcoma (SS) is a recalcitrant neoplasm with low chemosensitivity. We recently reported that recombinant methioninase (rMETase) inhibited SS growth in a patient-derived orthotopic xenograft (PDOX) mouse model and was more effective when administered in combination with the first-line drug doxorubicin (DOX). Caffeine enhances the efficacy of anticancer drugs by overcoming drug-induced cell-cycle arrest and increasing subsequent apoptosis. Read More

University of Texas Medical Branch 301 University Boulevard, Galveston, Texas, 77555, USA.

Parapharyngeal space sarcomas are rare malignancies and most in the reported literature are synovial sarcomas. Here we present the case of a 27-year-old female with a painless, left-sided neck mass who underwent computed tomography and magnetic resonance imaging evaluation which demonstrated a benign appearing mass that upon resection unexpectedly proved to be a high-grade undifferentiated sarcoma with rhabdoid features. Staging computed tomography revealed a synchronous renal cell carcinoma with clear cell and papillary features. Read More

In silico and in vitro screening of small molecule Inhibitors against SYT-SSX1 fusion protein in synovial sarcoma.

Comput Biol Chem 2018 Dec 6;77:36-43. Epub 2018 Sep 6.

Dept of Molecular Oncology, Dr. S. Krishnamurthi Campus, Cancer Institute (WIA), Guindy, Chennai, 600036, India. Electronic address:

Synovial sarcoma (SS) is characterized by a tumour specific chromosomal translocation t(X;18) (p11;q11) which results in the formation of SYT-SSX1 fusion protein. This fusion protein represents a clear therapeutic target and molecules specifically targeting SYT-SSX1 fusion protein are currently not available. In this study, SYT-SSX1 fusion protein sequence was retrieved from Uniprot and 3D structure was generated using I-TASSER modeling program. Read More

PET in the Diagnostic Management of Soft Tissue Sarcomas of Musculoskeletal Origin.

PET Clin 2018 Oct;13(4):609-621

Keck School of Medicine, University of Southern California (USC), 1520 San Pablo Street, Suite L1600, Los Angeles, CA 90033.

Soft tissue sarcomas (STSs) account for less than 1% of adult solid tumors and about 7% of pediatric malignancies, causing 2% of cancer-related deaths. With the advent of PET-computed tomography (CT), the value of (18) fluorine-2-fluoro-2-deoxy-d-glucose (FDG) PET imaging to improve the management of STSs has been explored. FDG PET imaging has been found useful in restaging and treatment response assessment. Read More
