Authors: Boguñá N, Capdevila L, Jané-Salas E Abstract Over the last few decades, the human papillomavirus (HPV) infection has emerged as a new epidemic and become a health issue due to its involvement in several cancers affecting the cervix, the anogenital region and the oropharynx. In this review, we aim to understand and explain the distinctive features of HPV-related oropharyngeal squamous cell carcinoma based on its epidemiological data, risk factors, specific topography, HPV subtypes most frequently involved, HPV-status diagnosis, clinical behaviour, prognosis, treatment, and preventive me...

Radical treatment strategies for locally advanced squamous cell carcinoma of the head and neck (LASCCHN) are centred on a multidisciplinary approach with options ranging from primary chemoradiotherapy (CRT) to surgical resection, followed by radiotherapy or CRT depending on pathological risk factors. Such intensive regimens have reduced recurrence rates, often at the cost of organ dysfunction and reduced quality of life [1,2]. Indeed, there have been moves to de-escalate treatment in those with human papillomavirus (HPV)-positive tumours who have better prognosis [3], with trials geared towards reducing toxicities while ma...

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 ...

Papillomaviridae is a family of small non-enveloped icosahedral viruses with double-stranded circular DNA. More than 200 different human papillomaviruses (HPVs) have been listed so far. Based on epidemiological data, a subgroup of alphapapillomaviruses (alpha HPVs) was referred to as high-risk (HR) HPV types. HR HPVs are the etiological agents of anogenital cancer and a subset of head and neck cancers. The cutaneous HPV types, mainly from beta and gamma genera, are widely present on the surface of the skin in the general population. However, there is growing evidence of an etiological role of betapapillomaviruses (beta HPV...

Authors: You EL, Henry M, Zeitouni AG Abstract Oropharyngeal cancer (opc) has become the leading site for human papillomavirus (hpv)-associated cancers in humans. It is an epidemic that remains relatively unfamiliar to most physicians, potentially delaying diagnosis and treatment. Traditionally, cancers involving the head and neck have occurred in smokers and in those with a significant alcohol history. Typically, hpv-positive opc presents in a younger, healthier population with a different set of risk factors and good prognosis for survival. However, many head-and-neck cancer patients, including those with hpv-pos...

Publication date: Available online 2 May 2019Source: Microbial PathogenesisAuthor(s): Mushfiq H. Shaikh, Vuk Bortnik, Nigel AJ. McMillan, Adi IdrisAbstractHead and neck cancers (HNCs) are a major health problem and a leading cause of morbidity and mortality worldwide. More than 90% of these tumours are head and neck squamous cell carcinomas (HNSCCs). Amongst the common risk factors for HNCs (tobacco and alcohol use), there is a strong association of human papillomavirus (HPV) with HNSCCs. HPV type 16 (HPV 16), the major high-risk HPV type, is most commonly associated with HPV-driven HNSCCs. The promiscuous nature of the ma...

In addition to their antimicrobial activities, they possess other functions; e.g., cell activation, proliferation, regulation of cytokine/chemokine production, migration, diffe...

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...

Purpose of review The systemic therapies available in recurrent and metastatic head and neck squamous cell carcinoma to date are palliative-intent treatments in most cases. However, a small subgroup of patients derives unconventional benefit and become long-term survivors, achieving cure in some cases. This review focusses on this group of patients, discusses recent literature and suggests plausible molecular hypothesis. Recent findings Human papillomavirus-related disease is known to confer a better prognosis in metastatic patients, probably because of its greater sensitivity to systemic therapies. This group of pati...
