Prevalence of Oral HPV Infection Higher Among Men Than Women

CHICAGO -- The overall prevalence of oral human papillomavirus (HPV) infection is approximately 7 percent among men and women ages 14 to 69 years in the United States, while the prevalence among men is higher than among women, according to a study appearing in JAMA. The study is being released early online to coincide with its presentation at the Multidisciplinary Head and Neck Cancer Symposium. Oral HPV infection is the cause of a subset of oropharyngeal [relating to the mouth and pharynx] squamous cell carcinomas (OSCC). Human papillomavirus positive OSCC are associated with sexual behavior in contrast to HPV-negative OSCC that are associated with chronic tobacco and alcohol use. At least 90 percent of HPV-positive OSCC are caused by high-risk (or oncogenic) HPV type 16 (HPV-16), and oral infection confers an approximate 50-fold increase in risk for HPV-positive OSCC. The incidence of OSCC has significantly increased over the last 3 decades in several countries, and HPV has been directly implicated as the underlying cause, according to background information in the article. Although oral HPV infection is the cause of a cancer that is increasing in incidence in the United States, little is known regarding the epidemiology of infection. Maura L. Gillison, M.D., Ph.D., of the Ohio State University Comprehensive Cancer Center, Columbus, and colleagues examined the prevalence of oral HPV infection in the United States. The researchers used data from a cross-sectional study as part of the National Health and Nutrition Examination Survey (NHANES) 2009-2010, a statistically representative sample of the U.S. population. Men and women ages 14 [...]

Head and Neck Cancer Patients Benefit in Multidisciplinary Clinics

Source: Journal of Clinical Oncology Head and neck cancer (HNC) is a multidisciplinary condition. Multi-modality treatment is standard, especially the use of chemoradiation. Proper imaging (CT, MRI and PET), more accurate pathologic assessment and thoroughly tailored treatment plans that limits radiation fields and doses and take into consideration surgical options that minimize morbidity (endoscopic and robotic procedures) are essential. Furthermore, dental, swallowing, speech, nutritional, financial and social support are also cornerstones in this comprehensive approach. However, the most important function might be the role of the nurse navigator in order to offer true coordinated care for our patients. Within William Beaumont Oncology Network we initiated multi-disciplinary clinics for HNC in January 2010 in which our specialists meet the patients together after discussion at the tumor board to streamline management. Methods: In this initial analysis we studied 15 randomly chosen patients’ way through our health care system in 2009, and compared with 15 randomly chosen patients in 2010, after the initiation of the Multi-Disciplinary Clinic. All patients had biopsy verified HNC, the vast majority being squamous cell carcinomas, and were stage III or stage IV. The radiation techniques were unchanged during study and treating physicians remained the same as well. Results: The first group of patients that did not go through our multi-disciplinary clinic had a mean time of 59 days (range 4-156) from pathologic diagnosis to start of radiation. Corresponding mean time for patients going through the multi-disciplinary clinics was 33 days (range 18-86), a decrease of 44%. Conclusions: Coordinated [...]

Gene may hold key to reducing spread of oral cancers

Source: University of Illinois Author: Sam Hostettler The spread of cancer cells in the tongue may be reduced if a gene that regulates cancer cell migration can be controlled, according to new research at the University of Illinois at Chicago. Oral cancer is an under-treated and poorly understood disease, says Xiaofeng "Charles" Zhou, assistant professor in the UIC Center for Molecular Biology of Oral Diseases and lead researcher of the study. More than 90 percent of oral cancers are squamous cell carcinomas that normally start on the gums, floor of the mouth, or tongue. About 30,000 Americans are affected each year, Zhou said. While new cancers of all types have risen 8 percent in the last five years, oral cancer increased 21 percent, according to the American Cancer Society. Tongue squamous cell carcinoma, one of the most frequent oral cancers, rose more than 37 percent in this period. And although overall cancer deaths decreased during this period, those due to oral cancer increased by 4 percent -- and those due to tongue squamous cell carcinoma by 10 percent. Improvements in patient survival require better understanding of tumor invasion and how cancer spreads, Zhou said, so that aggressive tumors can be detected early and targeted therapies can be developed. While researchers have tried to identify altered genes that contribute to the aggressive nature of tongue squamous cell carcinoma, most previous studies have focused on protein-encoding genes, Zhou said. The new study examines a noncoding gene called microRNA-138. MicroRNAs are small, noncoding [...]
