Increasing incidence rates of oropharyngeal squamous cell carcinoma in Germany and significance of disease burden attributed to human papillomavirus.

Cancer Prev Res (Phila) 2019 Apr 19. Epub 2019 Apr 19.

Department of Otolaryngology, Head and Neck Surgery, University Hospital Cologne.

Increasing incidences of head and neck cancers and rising proportions of these associated with human papilloma virus (HPV), especially in the oropharynx, have been reported in international studies. So far, the trends and contribution of HPV to the number of newly diagnosed cases of oropharyngeal squamous cell carcinomas (OPSCC) in Germany are uncertain. We investigated HPV association and incidence rates in a cohort of consecutively included patients with OPSCC in Giessen 2000-2017, and compared our results with regional (Giessen and the federal state of Hesse), national (Germany) and international (USA) databases.

Refining our understanding of cervical neoplasia and its cellular origins.

Papillomavirus Res 2019 Apr 8. Epub 2019 Apr 8.

Department of Pathology, Tennis Court Road, University of Cambridge, Cambridge, CB2 1QP, UK.

Human papillomaviruses (HPV) cause cancer at a number of vulnerable epithelial sites, including the cervix, the anus and the oropharynx, with cervical cancer being the most significant in terms of numbers. The cervix has a complex epithelial organisation, and comprises the stratified epithelium of the ectocervix, the columnar epithelium of the endocervix, and the cervical transformation zone (TZ). Most cervical cancers arise at the TZ, which is a site where a stratified squamous epithelium can develop via metaplasia from a simple columnar epithelium. Read More

Human Papillomavirus Genotype Detection in Oral Gargle Samples Among Men With Newly Diagnosed Oropharyngeal Squamous Cell Carcinoma.

JAMA Otolaryngol Head Neck Surg 2019 Mar 28. Epub 2019 Mar 28.

Center for Immunization and Infection Research in Cancer, Tampa, Florida.

Importance: The most common cause of oropharyngeal squamous cell carcinoma is human papillomavirus (HPV) infection, and currently the standard of care to determine the HPV infection status in this type of carcinoma is to use p16 immunohistochemistry as a surrogate marker of high-risk HPV infection. Although p16 immunohistochemistry is limited by the inability to determine the specific HPV genotypes, oral gargle samples may be a readily available source of HPV DNA for genotyping.

Objective: To determine the specific HPV genotypes present in both oral gargle samples and tumor specimens. Read More

Optimising Radiation Therapy Dose to the Swallowing Organs at Risk: An In Silico Study of feasibility for Patients with Oropharyngeal Tumours.

Dysphagia 2019 Feb 11. Epub 2019 Feb 11.

Radiation Oncology, Nelune Comprehensive Cancer Centre, POWH, Sydney, NSW, 2031, Australia.

Recent evidence suggests that reducing radiotherapy dose delivered to specific anatomical swallowing structures [Swallowing Organs at Risk (SWOARs)] may improve swallowing outcomes post-treatment for patients with head and neck cancer. However, for those patients with tumours of the oropharynx, which typically directly overlap the SWOARs, reducing dose to these structures may be unachievable without compromising on the treatment of the disease. To assess the feasibility of dose reduction in this cohort, standard IMRT plans (ST-IMRT) and plans with reduced dose to the SWOARs (SW-IMRT) were generated for 25 oropharyngeal cancer patients (Brouwer et al.

Weekly paclitaxel, carboplatin, cetuximab, and cetuximab, docetaxel, cisplatin, and fluorouracil, followed by local therapy in previously untreated, locally advanced head and neck squamous cell carcinoma.

Ann Oncol 2019 Mar;30(3):471-477

Department of Thoracic/Head and Neck Medical Oncology, University of Texas MD Anderson Cancer Center, Houston.

Background: The survival advantage of induction chemotherapy (IC) followed by locoregional treatment is controversial in locally advanced head and neck squamous cell carcinoma (LAHNSCC). We previously showed feasibility and safety of cetuximab-based IC (paclitaxel/carboplatin/cetuximab-PCC, and docetaxel/cisplatin/5-fluorouracil/cetuximab-C-TPF) followed by local therapy in LAHNSCC. The primary end point of this phase II clinical trial with randomization to PCC and C-TPF followed by combined local therapy in patients with LAHNSCC stratified by human papillomavirus (HPV) status and T-stage was 2-year progression-free survival (PFS) compared with historical control.

Dynamic tonsillar prolapse masquerading as paradoxical vocal fold movement dysfunction.

Int J Pediatr Otorhinolaryngol 2019 Mar 2;118:68-72. Epub 2018 Dec 2.

Division of Pediatric Otolaryngology, UPMC Children's Hospital of Pittsburgh, USA.

Introduction: Paradoxical vocal fold movement dysfunction (PVFMD) is a disorder in which the vocal folds involuntarily adduct during inspiration resulting in stridor, cough, dysphonia and dyspnea. Diagnosis of PVFMD is difficult given the episodic nature of the disorder and the often-normal laryngeal exam in between episodes. Moreover, additional sources of obstruction have been identified as sources of Periodic Occurrence of Laryngeal Obstruction (POLO). Read More

Development of an Oropharyngeal Scope with an Integrated Tongue Depressor: NTOP2013 Study.

Acta Med Okayama 2018 Dec;72(6):611-614

Department of Artificial Organs Medical Device Creation, Tokyo Medical Center, Tokyo 152-8902,

The oropharynx is examined with a light source such as an electric light, a penlight, or a forehead mirror based on an acquired visual field using a tongue depressor. However, it is extremely difficult to obtain objective and reproducible images of tissue within the pharynx required in recent years with these methods, and insufficient progress in the examination tools has been made. There is an increasing need to develop a method for display during oropharyngeal examination. Read More
