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

KRAS mutation in secondary malignant histiocytosis arising from low grade follicular lymphoma.

Diagn Pathol 2018 Oct 15;13(1):78. Epub 2018 Oct 15.

Department of Pathology, Northwestern University Feinberg School of Medicine, 251 E Huron Street, Chicago, IL, 60611, USA.

Background: Transformation of follicular lymphoma most typically occurs as diffuse large B-cell lymphoma, however other forms of transformation such as classic Hodgkin lymphoma and lymphoblastic transformation can occur. Secondary malignant histiocytosis also represents a rare form of transformation, which is thought to occur due to a process of transdifferentiation whereby the lymphoma cells exhibit lineage plasticity and lose all evidence of B-cell phenotype and instead acquire the phenotype of a histiocytic neoplasm. Little is known about the underlying genetic alterations that occur during this unusual process. Read More

PD1 cells associate with clusters of proliferating B-cells in marginal zone lymphoma.

Diagn Pathol 2018 Sep 15;13(1):74. Epub 2018 Sep 15.

Leicester Cancer Research Centre and Ernest and Helen Scott Haematology Research Institute, University of Leicester, Lancaster Road, Leicester, LE1 7HB, UK.

Background: Abnormally sustained immune reactions drive B-cell proliferation in some cases of marginal zone lymphoma but the CD4 T-cell subsets, which are likely to contribute to the B-cell responses in the tumour microenvironment, are not well characterised and neither has the spatial distribution of the different subsets in involved lymph nodes been investigated.

Methods: Employing a workflow of multiplex semi-automated immunohistochemistry combined with image processing we investigated association between infiltrating T-cells and proliferating lymphoma B-cells.

Results: Both total numbers of activating follicular helper (Tfh) cells (defined by high expression of PD1) and suppressive regulatory (Treg) T-cells (defined by FOXP3 expression) and the Tfh:Treg ratio, assessed over relatively large areas of tissue, varied among cases of marginal zone lymphoma.

Increased expression of claudin-17 promotes a malignant phenotype in hepatocyte via Tyk2/Stat3 signaling and is associated with poor prognosis in patients with hepatocellular carcinoma.

Diagn Pathol 2018 Sep 15;13(1):72. Epub 2018 Sep 15.

Stem Cell and Cancer Center, The First Bethune Hospital, Jilin University, Changchun, Jilin, 130021, People's Republic of China.

Background: Hepatocellular carcinoma (HCC) is the second leading cause of cancer death in Asia; however, the molecular mechanism in its tumorigenesis remains unclear. Abnormal expression of claudins (CLDNs), a family of tight junction (TJ) proteins, plays an important role in the metastatic phenotype of epithelial-derived tumors by affecting tight junction structure, function and related cellular signaling pathways. In a previous study, we used a tissue chip assay to identify CLDN17 as an upregulated gene in HCC. Read More
