Human Papillomavirus Detection in Head and Neck Squamous Cell Carcinomas at a Tertiary Hospital in Sub-Saharan Africa.
Human Papillomavirus Detection in Head and Neck Squamous Cell Carcinomas at a Tertiary Hospital in Sub-Saharan Africa. ScientificWorldJournal. 2019;2019:2561530 Authors: Aboagye E, Agyemang-Yeboah F, Duduyemi BM, Obirikorang C Abstract Fewer studies have been done over the years to establish the association of human papillomavirus (HPV) with head and neck squamous cell carcinoma (HNSSC) within the subregions of sub-Saharan Africa, and thus this study was designed to investigate the presence of HPV in HNSCC at a tertiary hospital in Ghana, providing additional evidence on the need to explore similar studies in other subregions. A retrospective cross-sectional study was employed to investigate the presence of the DNA of HPV genotypes in HNSCC archived tissue. A total of 100 HNSCC cases were classified as suitable for HPV genotyping. HPV-DNA was detected in 18% of the HNSCC cases, with 17 being HPV-16 and 1 dual infection with HPV-16 and HPV-18. HPV was prevalent in 50% of oropharyngeal cancers, 27% of laryngeal cancers, and 23% of oral cavity cancers. HPV E6/E7 oncogenic DNA was found in 18% of the HNSCC cases, with HPV-16 being the predominant genotype present. The pattern of HPV association was similar to earlier reported studies, recording a higher prevalence in oropharyngeal cancers, followed by laryngeal cancers and oral cavity cancers.

The objective of this review article is to discuss the current role of surgery as the primary treatment modality in patients with head and neck squamous cell carcinoma (HNSCC). Recent findings HNSCC represents one of the cancer locations where the primary treatment modality is the most under discussion. Indeed, the respective roles of primary surgical resection followed, as necessary, by adjuvant radiotherapy or definitive chemoradiotherapy remain controversial. The results of organ preservation trials and the drastic rise in the incidence of human papillomavirus-induced oropharyngeal tumors, which are known to be highl...
Authors: Yang H, Cao Y, Li ZM, Li YJ, Jiang WQ, Shi YX Abstract Cyclin-dependent kinase inhibitor 2A (p16INK4a) protein is a surrogate immunohistochemical marker of human papillomavirus infection in oropharynx squamous cell carcinoma (OPSCC). However, the effects of p16INK4a in non-OPSCC require additional analysis. In addition, major gaps remain in the literature, including small volumes of data for China. Therefore, the present study evaluated the frequency of p16INK4a positivity in patients with non-OPSCC in Southern China, and assessed its prognostic value. p16INK4a expression status in patients with non-OPSCC ...
CONCLUSION: The prevalence of HNSCC is modest compared with other cancers in HIV-infected individuals. The prevalence of oropharynx carcinoma, a potentially HPV-related carcinoma, seems to increase over time. Even if tobacco may be an important contributor, the role of HPV in HIV-infected individuals presenting with HNSCC should be investigated. PMID: 29887186 [PubMed - as supplied by publisher]
CONCLUSION: Oropharynx cancer with significant p16 expression showed an increased overall survival and elevated T- and B-lymphocyte infiltration, which suggests a prognostic relevance of immune cell infiltration. PMID: 29493423 [PubMed - as supplied by publisher]
This article is a continuation of the “Do You Know Your Guidelines” series, initiated by the Education committee of the American Head and Neck Society. Treatment guidelines for advanced head and neck squamous cell carcinoma are reviewed here, including the critical roles of radiotherapy, chemotherapy, and the recent application of immunotherapy agents. We will be limiting this discussion to include cancers of the oral cavity, oropharynx, hypopharynx, and larynx. It should be noted that much of the article pertains to human papillomavirus (HPV)‐negative oropharyngeal cancer where applicable, as HPV‐positive ...
Conclusion: BM in HNSCC is mostly multiple, associated with extracranial metastasis and can occur in patients without locoregional relapse or residual disease and carries a dismal outcome.
BackgroundTreatment intensification for resected, high-risk, head and neck squamous cell carcinoma (HNSCC) is an area of active investigation with novel adjuvant regimens under study. In this trial, the epidermal growth-factor receptor (EGFR) pathway was targeted using the IgG2 monoclonal antibody panitumumab in combination with cisplatin chemoradiotherapy (CRT) in high-risk, resected HNSCC.Patients and methodsEligible patients included resected pathologic stage III or IVA squamous cell carcinoma of the oral cavity, larynx, hypopharynx, or human-papillomavirus (HPV)-negative oropharynx, without gross residual tumor, featur...
ConclusionsAs such, GAL and GALR1/2 methylation status may serve as an important site‐specific biomarker for prediction of clinical outcome in patients with HNSCC. This article is protected by copyright. All rights reserved
ConclusionThe findings confirm the association between smoking history and survival and the importance of clinical variables in evaluating smoking as a prognostic factor. Timing, intensity, and duration of cigarette use should be considered with other prognostic factors when considering risk stratification for treatment planning. © 2016 Wiley Periodicals, Inc.

Conclusions The present data do not provide evidence for a role of genetic variations in EVER1 or EVER2 for HPV status of mucosal HNSCC or between HNSCC patients and controls.
