A Mouse Model of Oropharyngeal Papillomavirus-Induced Neoplasia Using Novel Tools for Infection and Nasal Anesthesia.

Viruses 2020 Apr 16;12(4). Epub 2020 Apr 16.

McArdle Laboratory for Cancer Research, University of Wisconsin, Madison, WI 53705, USA.

Human head and neck cancers that develop from the squamous cells of the oropharynx (Oropharyngeal Squamous Cell Carcinomas or OPSCC) are commonly associated with the papillomavirus infection. A papillomavirus infection-based mouse model of oropharyngeal tumorigenesis would be valuable for studying the development and treatment of these tumors. We have developed an efficient system using the mouse papillomavirus (MmuPV1) to generate dysplastic oropharyngeal lesions, including tumors, in the soft palate and the base of the tongue of two immune-deficient strains of mice.

Threshold for interpretation of p16 immunostaining in fine-needle aspirate specimens of metastatic oropharyngeal squamous cell carcinoma.

J Am Soc Cytopathol 2020 May - Jun;9(3):177-184. Epub 2020 Feb 11.

Department of Pathology, University of Mississippi Medical Center, Jackson, Mississippi.

Introduction: Human papilloma virus (HPV)-associated oropharyngeal squamous cell carcinoma (HPV-OPSCC) has been recognized to have an excellent response to treatment and has a distinct pathologic staging. For this reason, HPV testing is recommended in cytology specimens of metastatic OPSCC, although the guidelines for testing are not clearly defined. The aim of the current study was to establish a threshold for interpretation of p16 in aspirates from metastatic OPSCC. Read More

[Diagnostics and treatment of adenotonsillar hyperplasia in children].

HNO 2020 Mar;68(3):215-226

Klinik für Hals‑, Nasen- und Ohrenheilkunde, Universitätsklinikum Ulm, Frauensteige 12, 89075, Ulm, Deutschland.

Adenoidectomy, paracentesis, and tonsillar interventions are the most common operations in childhood. Hypertrophy of the lymphatic tissue of Waldeyer's ring can lead to individually distinct, acute, and chronic symptoms as well as anatomical and functional changes. When presented with affected children in otolaryngologic practice, the combination of parental interview, questionnaire-based screening for obstructive sleep apnea syndrome, and physical examination including ear microscopy, inspection of the oropharynx and, if necessary, the nasopharynx, has proven its worth.

Inclusion of an E7 DNA Amplification Test Improves the Robustness of Human Papillomavirus-Associated Oropharyngeal Squamous Cell Carcinoma Diagnosis.

World J Oncol 2020 Feb 2;11(1):1-8. Epub 2020 Feb 2.

Otolaryngology, Georgetown University School of Medicine, Veterans Affairs Medical Center, Washington, DC, USA.

Background: The rise in human papillomavirus (HPV) infection rates over the last few decades in the USA has contributed to a significant increase in the overall incidence of patients diagnosed with squamous cell carcinoma of the head and neck. These head and neck carcinomas develop in the oropharynx, with more than 90% of them caused by infection with high-risk HPV type 16. Patients diagnosed with HPV-induced oropharyngeal squamous cell carcinomas (OPSCCs) have a better prognosis and treatment response than those diagnosed with head and neck cancers caused by alcohol consumption and tobacco use.

The Appearance of 4-Hydroxy-2-Nonenal (HNE) in Squamous Cell Carcinoma of the Oropharynx.

Molecules 2020 Feb 16;25(4). Epub 2020 Feb 16.

Rudjer Boskovic Institute, Laboratory for Oxidative Stress, Bijenička cesta 54, 10000 Zagreb, Croatia.

Tumor growth is associated with oxidative stress, which causes lipid peroxidation. The most intensively studied product of lipid peroxidation is 4-hydroxy-2-nonenal (HNE), which is considered as a "second messenger of free radicals" that binds to proteins and acts as a growth-regulating signaling factor. The incidence of squamous cell carcinoma of the oropharynx is associated with smoking, alcohol and infection of human papilloma virus (HPV), with increasing incidence world-wide. Read More

Treatment de-escalation for HPV-associated oropharyngeal squamous cell carcinoma with radiotherapy vs. trans-oral surgery (ORATOR2): study protocol for a randomized phase II trial.

BMC Cancer 2020 Feb 14;20(1):125. Epub 2020 Feb 14.

Department of Radiation Oncology, London Health Sciences Centre, Western University, 800 Commissioners Rd. E, London, Ontario, N6A 5W9, Canada.

Background: Patients with human papillomavirus-positive (HPV+) oropharyngeal squamous cell carcinoma (OPC) have substantially better treatment response and overall survival (OS) than patients with HPV-negative disease. Treatment options for HPV+ OPC can involve either a primary radiotherapy (RT) approach (± concomitant chemotherapy) or a primary surgical approach (± adjuvant radiation) with transoral surgery (TOS). These two treatment paradigms have different spectrums of toxicity. Read More

Progression of chronic wasting disease in white-tailed deer analyzed by serial biopsy RT-QuIC and immunohistochemistry.

PLoS One 2020 14;15(2):e0228327. Epub 2020 Feb 14.

Department of Microbiology, Immunology, and Pathology, Prion Research Center, College of Veterinary Medicine and Biomedical Sciences, Colorado State University, Fort Collins, Colorado, United states of America.

Chronic wasting disease (CWD) continues to spread or be recognized in the United States, Canada, and Europe. CWD is diagnosed by demonstration of the causative misfolded prion protein (PrPCWD) in either brain or lymphoid tissue using immunodetection methods, with immunohistochemistry (IHC) recognized as the gold standard. In recent years, in vitro amplification assays have been developed that can detect CWD prion seeding activity in tissues, excreta, and body fluids of affected cervids. Read More

Pathobiology 2020 7;87(2):75-86. Epub 2020 Feb 7.

Radiation and Clinical Oncology Department, Maria Sklodowska-Curie National Research Institute of Oncology Gliwice Branch, Gliwice, Poland.

Introduction: Human papillomavirus with a high oncogenic potential (HR-HPV) is responsible for more than a half of squamous cell carcinomas of the oropharynx. The HR-HPV-dependent cases of this tumour have a better prognosis compared to the HR-HPV-negative cases, despite the usually more advanced disease at the time of diagnosis. In addition to genetic and epigenetic factors, the causes of this more favourable course of the disease are also seen in the participation of the tumour microenvironment, including the patient's immune system.
