BACKGROUND: The incidence of oropharyngeal squamous cell carcinoma (OPSCC) caused by oncogenic human papillomavirus (HPV) is rising worldwide. HPV-OPSCC is commonly diagnosed by RT-qPCR of HPV E6 and E7 oncoproteins or by p16 immunohistochemistry (IHC). Droplet digital PCR (ddPCR) has been recently reported as an ultra-sensitive and highly precise method of nucleic acid quantification for biomarker analysis. To validate the use of a minimally invasive assay for detection of oncogenic HPV based on oropharyngeal swabs using ddPCR...

Importance: Human papillomavirus (HPV)-negative oropharyngeal squamous cell carcinoma (OPSCC) has shown resistance to conventional concurrent chemoradiation (CRT) therapy and carries a relatively poor prognosis in comparison with HPV-positive disease, with decreased locoregional control and overall survival (OS). In the present analysis, we examine whether upfront surgical resection improves overall survival in a large national sample. Objective: To compare survival outcomes among patients with newly diagnosed cT1-2 N1-2b HPV-negative OPSCC when treated with primary surgical resection vs CRT...

There is an increasing incidence of oropharyngeal squamous cell carcinoma (OPSCC) in the western world due to human papillomavirus (HPV). According to the Danish Head and Neck Cancer Group guidelines, the current recommended treatment of patients with OPSCC in Denmark is primary radiation therapy (RT) with or without concomitant chemotherapy. This is the first study in Scandinavia from a head and neck cancer centre that aims to demonstrate the feasibility of performing primary transoral robotic surgery (TORS) and concurrent neck dissection for patients with early stage OPSCC...

Recent studies have suggested that immune cells as part of tumor's microenvironment could partly explain the better outcome in HPV-associated oropharyngeal carcinoma. We performed a systematic review of the literature focused on differences in immune-infiltrate in HPV+ versus HPV- oropharyngeal cancers. This comprehensive search yielded 4308 original papers, of which 20 satisfied our eligibility criteria. Increase in both circulating and tumor infiltrating CD8+ lymphocytes is mainly seen in HPV+ oropharyngeal carcinoma...

Purpose Human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (OPSCC) is treatment-responsive. Definitive chemoradiation results in high cure rates but causes long-term toxicity and may represent overtreatment of some patients. This phase II trial evaluated whether complete clinical response (cCR) to induction chemotherapy (IC) could select patients with HPV-associated OPSCC for reduced radiation dose as a means of sparing late sequelae. Methods Patients with HPV16 and/or p16-positive, stage III-IV OPSCC received three cycles of IC with cisplatin, paclitaxel, and cetuximab...

BACKGROUND: Despite controversy surrounding its benefit, the use of concomitant chemoradiotherapy (CCRT) in patients with oropharyngeal squamous cell carcinoma (OPSCC) who are aged > 70 years is increasing. However, to the authors' knowledge, few studies to date have compared the outcomes of different systemic treatments in this population. METHODS: Records from 74 patients aged ≥ 70 years with stage III to stage IVB OPSCC who were undergoing CCRT from 2002 to 2013 at a single institution were reviewed...

BACKGROUND: More than 400,000 cases of oropharyngeal squamous cell carcinoma (OPSCC) are diagnosed each year worldwide and the incidence is rising, partly as a result of human papillomavirus. Human papillomavirus-associated OPSCC affects younger patients and often presents at a higher stage; however, it is associated with a better prognosis.Until recently, first-line management of OPSCC involved chemoradiotherapy, as research had demonstrated comparable survival outcomes when compared with open surgery, with significantly decreased morbidity...

Clinical laboratories are expected to reliably identify human papilloma virus (HPV) associated oropharyngeal squamous cell carcinoma (OPSCC) for prognostic and potential therapeutic applications. In addition to surrogate p16 immunohistochemistry (IHC) testing, DNA-based HPV-specific testing strategies are widely utilized. Recognizing the efficiency of the Roche Cobas 4800 platform for testing gynecological cytology specimens for high-risk HPV, we elected to evaluate the potential utility of this platform for testing formalin-fixed paraffin-embedded (FFPE) OPSCC tissue...

Head and neck squamous cell carcinoma (HNSCC) is generalized term that encompasses a diverse group of cancers that includes tumours of the oral cavity (OSCC), oropharynx (OPSCC) and nasopharynx (NPC). Genetic alterations that are common to all HNSCC types are likely to be important for squamous carcinogenesis. In this study, we have investigated the role of the homeodomain-only homeobox gene, HOPX, in the pathogenesis of HNSCC. We show that HOPX mRNA levels are reduced in OSCC and NPC cell lines and tissues and there is a general reduction of HOPX protein expression in these tumours and OPSCCs...

Importance: Human papillomavirus (HPV)-related oropharyngeal squamous cell carcinoma (OPSCC) has a favorable prognosis, and p16 immunohistochemistry is a surrogate marker of high-risk HPV infection and strong prognosticator. Given this favorable prognosis, treatment de-escalation for p16-positive OPSCC is now being considered with the goal of decreasing treatment-associated morbidity without compromising tumor control. The role of adjuvant chemotherapy in this setting is becoming increasingly unclear...

BACKGROUND: Few studies have addressed how human papilloma virus (HPV) infection in oropharyngeal squamous cell carcinoma (OPSCC) affects the outcome of surgical therapy; furthermore, the relationship between the presence of HPV DNA and neck lymph node (LN) metastasis has not been well established. METHODS: A total of 65 patients who underwent surgery as a first-line therapy for OPSCC were enrolled in this study. In HPV-positive patients, the presence of HPV DNA in metastatic neck LN lesions was evaluated...

BACKGROUND: Human papillomavirus (HPV) is a critical element in the rising incidence of oropharyngeal squamous cell carcinoma (OPSCC), although whether this trend will continue, and the types of HPV responsible, are currently unknown. We previously demonstrated an increased incidence of HPV-related OPSCC in the high HPV prevalence area of Eastern Denmark from 2000 to 2010. Therefore, we investigated if the incidence for OPSCC continued to rise, the association to HPV and putative HPV-types in Eastern Denmark from 2011 to 14...

PurposeThere is a paucity of biomarkers to predict failure in human papilloma-virus positive (HPV+) oropharyngeal squamous cell carcinoma (OPSCC) following curative therapy. E6/E7 viral oncoproteins are constitutively expressed in HPV+ tumors and highly immunogenic, resulting in readily detected serum antibodies. The purpose of this study is to determine if serum E6 and E7 antibody levels can potentially serve as a biomarker of recurrence in patients with HPV+OPSCC. Experimental DesignWe evaluated E6/E7 antibody levels in patients with previously untreated, advanced stage(III, IVa-b), HPV+OPSCC receiving definitive chemoradiation under a uniform protocol from 2003-2010...

Extracapsular spread (ECS) is one of the most important prognostic factors in head and neck squamous cell carcinoma (HNSCC). However, despite its major clinical relevance, there are still a number of important remaining issues regarding this condition. Indeed, standardized diagnostic and grading criteria of ECS are still lacking. The imaging modality of choice for its diagnosis is a matter of debate. Current research looking at the identification of specific biomarkers is ongoing. Recent findings demonstrate a direct correlation between the level of extension of ECS and a poor prognosis...

OBJECTIVE: The rapid worldwide rise in incidence of human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC) has generated studies confirming this disease as an entity distinct from traditional OPSCC. Based on pathology, surgical studies have revealed prognosticators specific to HPV-positive OPSCC. The current AJCC/UICC staging and pathologic nodal (pN)-classification do not differentiate for survival, demonstrating the need for new, HPV-specific OPSCC staging...

Purpose In squamous cell carcinomas of the head and neck (HNSCC), the increasing incidence of oropharyngeal squamous cell carcinomas (OPSCCs) is attributable to human papillomavirus (HPV) infection. Despite commonly presenting at late stage, HPV-driven OPSCCs are associated with improved prognosis compared with HPV-negative disease. HPV DNA is also detectable in nonoropharyngeal (non-OPSCC), but its pathogenic role and clinical significance are unclear. The objectives of this study were to determine whether HPV plays a causal role in non-OPSCC and to investigate whether HPV confers a survival benefit in these tumors...
