Inadequate target volume delineation and local-regional recurrence after intensity-modulated radiotherapy for human papillomavirus-positive oropharynx cancer.

CONCLUSION: A significant proportion of local-regional recurrences from HPV-positive oropharyngeal cancer represented geographical misses which possibly could have been prevented with more meticulous attention to IMRT planning. This finding has important implications with respect to ongoing attempts to de-escalate radiation dose for this disease. Our data highlight the importance of robust quality assurance with careful review of target volumes prior to the initiation of IMRT. PMID: 28511960 [PubMed - as supplied by publisher]

We read with great interest the Oncology Scan article by Anderson et  al.1 The paper focused on the latest findings indicating that radiation therapy plus cetuximab led to inferior overall survival in human papillomavirus (HPV)–positive patients with oropharyngeal cancer (OPC), compared with standard concurrent platinum-based chemotherapy. The authors summarize an d comment on the recent results of 2 large prospective randomized trials2,3 published in January 2019 in The Lancet. Both trials were based on the hypothesis that substituting cisplatin with cetuximab could offer a valid, but less toxic, alternative as...

Authors: Okunade KS Abstract Cervical cancer is by far the most common HPV-related disease. About 99.7% of cervical cancer cases are caused by persistent genital high-risk human papillomavirus (HPV) infection. Worldwide, cervical cancer is one of the most common cancers in women with an estimated 528,000 new cases reported in 2012. Most HPV infections clear spontaneously but persistent infection with the oncogenic or high-risk types may cause cancer of the oropharynx and anogenital regions. The virus usually infects the mucocutaneous epithelium and produces viral particles in matured epithelial cells and then cause...

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]

AbstractIn the U.S. there is an epidemic of sexually transmitted diseases (STIs). One of the most prevalent STIs is the Human Papillomavirus (HPV). Certain high risk strains of HPV are believed to cause virtually all cervical cancers, over 90% of anal cancers, 70% of oropharyngeal cancers, and the majority of anal  genital warts. HPV is preventable through vaccination and is available for both men and women. Several educational interventions have been employed, yet baseline awareness and knowledge related to HPV and 9vHPV remains relatively low among young men. What is not known is the most effective method for provid...

Abstract Human papillomavirus (HPV) causes nearly all cervical cancers and some cancers of the vagina, vulva, penis, anus, and oropharynx (1).* Most HPV infections are asymptomatic and clear spontaneously within 1 to 2 years; however, persistent infection with oncogenic HPV types can lead to development of precancer or cancer (2). In the United States, the 9-valent HPV vaccine (9vHPV) is available to protect against oncogenic HPV types 16, 18, 31, 33, 45, 52, and 58 as well as nononcogenic types 6 and 11 that cause genital warts. CDC analyzed data from the U.S. Cancer Statistics (USCS)† to assess the incide...
