Nodal response after 46 Gy of intensity ‐modulated radiotherapy is associated with human papillomavirus–related oropharyngeal carcinoma

ConclusionsHPV‐related OPSCCs are associated with complete nodal response after 46 Gy of IMRT. Patients with full regional control (pN0) after IMRT and subsequent neck dissection show a significantly better overall survival, but smoking negatively interacts with this effect.

Authors: Durkova J, Boldis M, Kovacova S Abstract Over the course of the last two decades, there has been a decrease in the incidence of head and neck cancers thanks to a decreasing prevalence of smoking. However, a new risk factor has been coming to the fore: human papillomavirus infection (HPV). HPV-positive oropharyngeal squamous cell carcinoma (HPV+OPC) is more sensitive to chemotherapy and radiotherapy, which translates to a much better prognosis with conventional treatment protocols than tumours that are HPV-negative. Traditional therapeutic interventions are associated with substantial morbidity and have a g...

n Human papillomavirus (HPV) infection is the cause of a growing percentage of head and neck cancers (HNC); primarily, a subset of oral squamous cell carcinoma, oropharyngeal squamous cell carcinoma, and laryngeal squamous cell carcinoma. The majority of HPV-associated head and neck cancers (HPV + HNC) are caused by HPV16; additionally, co-factors such as smoking and immunosuppression contribute to the progression of HPV + HNC by interfering with tumor suppressor miRNA and impairing mediators of the immune system. This review summarizes current studies on HPV + HNC, ranging from potential modes of oral transmission of ...

In this issue of JAMA Otolaryngology –Head&Neck Surgery, Masroor at al explore the outcomes associated with adherence to the current National Comprehensive Cancer Network (NCCN) posttreatment surveillance recommendations for patients with human papillomavirus –associated oropharyngeal squamous cell carcinoma (HPV-associated OPSCC). Recognition of the favorable prognosis of HPV-associated OPSCC has led to the issue of whether the current NCCN-guided surveillance recommendations are appropriate for survivors of HPV-associated OPSCC. The goals of a regula r surveillance schedule are to identify cancer recurren...

Conclusion: PDX from OPSCC preserves important molecular characteristics of the human primary tumor. Radiosensitivity were in accordance with clinically observed treatment response. The PDX model is a clinically relevant surrogate model of head and neck cancer. Perspectives include increased understanding of disease biology, which could lead to development of novel treatments and biomarkers. PMID: 31510843 [PubMed - as supplied by publisher]

In conclusion, HPV-DNA prevalence was significantly lower in our HNSCC patients than worldwide 32–36% estimates (p ≤ 0.001). Although infrequent, oropharyngeal cancer increased over years and showed 21% HPV-DNA positivity, which is close to the worldwide 36–46% estimates (p = 0.16). Besides age, smoking, tumor stage, and treatment, HPV/p16 status was an important determinant of patients’ survival. The HPV and/or p16 positivity patients had a better OS than HPV/p16 double-negative patients (p = 0.05). Thus, HPV/p16 status helps improve prognosis by distinguishing between the more favorab...

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...

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 ...
