Prognostic value of HPV status among patients with hypopharyngeal carcinoma: a population-based study

AbstractObjectiveTo clarify the prognostic role of human papilloma virus (HPV) status among patients with hypopharyngeal carcinoma.MethodsSurveillance, Epidemiology and End Results (SEER) HPV head and neck cancer database has been accessed and cases with hypopharyngeal squamous cell carcinoma with known HPV status were retrieved. Kaplan –Meier survival estimates were used to evaluate the impact of HPV status on overall survival outcomes of included patients and multivariable cox regression analysis was used to assess the impact of HPV status on overall and head and neck cancer-specific survival.ResultsA total of 1157 patients ’ records with hypopharyngeal carcinoma were included in the current analysis. Using Kaplan–Meier survival estimates, patients with HPV positive status seem to have better overall survival compared to patients with HPV negative status (P

This study aimed to test the role of Cx43 protein on Bcl-2 expression, tumor progression and response to taxane-based treatment in HNSCC. Human papillomavirus (HPV) negative HNSCC cell lines were tested for paclitaxel sensitivity through measuring apoptosis induction, cell viability and changes in Cx43 and Bcl-2 levels using flow cytometry, cell viability assay, immunocytochemistry and western blot. Inhibition of Cx43 expression using siRNA increased Bcl-2 protein levels in SCC25 (tongue squamous cell carcinoma) cells, while forced Cx43 expression reduced Bcl-2 levels and supported paclitaxel cytotoxicity in FaDu (hypophar...

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...

Conclusions In the span of a very short time—less than a decade—robotic head and neck surgery has transformed the management of the head and neck cancer, and it seems clear that the future of treatment for these cancers lies in a multimodal approach in which TORS is likely to play an important role. Nevertheless, it is important to keep in mind that the current indications for TORS are limited and long-term data on the safety and oncological outcomes are needed to better understand the true role of TORS in treatment of head and neck cancer. Nonetheless, the emergence of ever more advanced robotic instruments i...

Objectives/HypothesisAnalyze the characteristics of second primary lung malignancies (SPLMs) following an index head and neck squamous cell carcinoma (HNSCC).Study DesignRetrospective cohort study.MethodsThe Surveillance, Epidemiology and End Results database was queried for all cases of HNSCC between 1973 and 2014 (N  = 101,856). This population was compared to a standard population to assess relative risk for lung cancer, calculated as the standardized incidence ratio (SIR). Patients who developed SPLMs were extracted (N = 8,116) and compared to all other cases of lung cancer (N =&thins...

Authors: Tribius S, Würdemann N, Laban S, Sharma SJ, Wagner S, Hoffmann TK, Wittekindt C, Klussmann JP Abstract Rising incidence rates in human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (OPSCC) and a significantly improved prognosis have brought this entity into scientific focus. At this year's American Society of Clinical Oncology (ASCO) Annual Meeting, 291 studies with the keyword "HPV" were presented, the majority of which were in head and neck cancer. Due to high rates of late toxicities after conventional therapy, de-intensified treatment concepts are being ...

Despite great enthusiasm towards immunotherapy, reliable biomarkers are still lacking. The importance of subsets based on human papillomavirus (HPV) status is supported by a growing body of evidence. However, role of other possible subgroups such as anatomic localization of primary tumor remains controversial. Our objective was to investigate immune cell infiltrate and checkpoint inhibitor proteins in above-mentioned head and neck cancer subsets. Archival tumor samples of 106 laryngeal, oropharyngeal, and hypopharyngeal cancer patients were stained with PD-L1, PD-L2, PD-1, and CTLA-4 antibodies. Proportion of tumor-infiltr...

Publication date: Available online 31 January 2018Source: Seminars in Cancer BiologyAuthor(s): Benjamin Solomon, Richard J. Young, Danny RischinAbstractHead and neck squamous cell carcinoma (HNSCC) comprises a heterogeneous group of tumors that arise from the squamous epithelium of the oral cavity, oropharynx, larynx and hypopharynx. While many HNSCCs are related to classical etiologic factors of smoking and alcohol, a clinically, genomically, and immunologically distinct subgroup of tumors arise from the epithelium of the tonsil and the base of tongue as a result of infection with Human Papilloma Virus (HPV). In this revi...

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]

Authors: Misawa K, Imai A, Mochizuki D, Mima M, Endo S, Misawa Y, Kanazawa T, Mineta H Abstract The aim of this study was to clarify the epigenetic regulation of ten eleven translocation protein (TET) family genes, which can provide insights into the mechanisms of tumorigenesis and the risk of disease recurrence in head and neck squamous cell carcinoma (HNSCC). We generated methylation profiles of TET1, TET2 and TET3 genes in tumor samples obtained from 233 patients with HNSCC; these included 57 hypopharynx, 44 larynx, 69 oral cavity, and 63 oropharynx tumor samples. The mRNA expression and promoter DNA methylation...
