Salivary Gland Cancer in the Era of Routine Next-Generation Sequencing.

Head Neck Pathol 2020 Jun 2;14(2):311-320. Epub 2020 Mar 2.

Department of Laboratory Medicine and Pathobiology, Toronto General Hospital, University Health Network, University of Toronto, 200 Elizabeth Street, Toronto, ON, M5G 2C4, Canada.

Next-Generation Sequencing (NGS) is being utilized with increasing frequency in the characterization of salivary gland tumours. The potential scenarios which may be encountered by using this technique in routine practice will be outlined in further text by drawing from our own clinical experience. These include oncocytic mucoepidermoid carcinomas with unusual variant morphology (and negative MAML2 fluorescent in-situ hybridization results), a diagnosis of ameloblastoma changed to adenoid cystic carcinoma (due to MYBL1 fusion presence), a salivary duct carcinoma with an ETV6-NTRK3 fusion (otherwise seen in secretory carcinomas) and novel fusion partners such as EWSR1-BEND2 (otherwise seen in pancreatic neuroendocrine carcinomas).

The role of Glial cell derived neurotrophic factor in head and neck cancer.

PLoS One 2020 21;15(2):e0229311. Epub 2020 Feb 21.

Department of Radiation Oncology, Stanford University School of Medicine, Stanford, California, United States of America.

Glial cell-derived neurotrophic factor (GDNF) is reported to promote the survival of neurons and salivary gland regeneration after radiation damage. This study investigated the effect of GDNF on cell migration, growth, and response to radiation in preclinical models of head and neck squamous cell carcinoma (HNSCC) and correlated GDNF expression to treatment outcomes in HNSCC patients. Our ultimate goal is to determine whether systemic administration of GDNF at high dose is safe for the management of hyposalivation or xerostomia in HNSCC patients. Read More

Tracing tumorigenesis in a solid tumor model at single-cell resolution.

Nat Commun 2020 02 20;11(1):991. Epub 2020 Feb 20.

Systems Biology of Gene Regulatory Elements, Berlin Institute for Medical Systems Biology, Max Delbrück Center for Molecular Medicine in the Helmholtz Association, Berlin, Germany.

Characterizing the complex composition of solid tumors is fundamental for understanding tumor initiation, progression and metastasis. While patient-derived samples provide valuable insight, they are heterogeneous on multiple molecular levels, and often originate from advanced tumor stages. Here, we use single-cell transcriptome and epitope profiling together with pathway and lineage analyses to study tumorigenesis from a developmental perspective in a mouse model of salivary gland squamous cell carcinoma.
