MedicalResearch.com Interview with: [caption id="attachment_50367" align="alignleft" width="200"]Praveen Arany, DDS, PhD Department of Oral Biology School of Dental Medicine University of Buffalo Dr. Arany[/caption] Praveen Arany, DDS, PhD Department of Oral Biology School of Dental Medicine University of Buffalo MedicalResearch.com: What is the background for this study? How is the light treatment delivered? Response: Cancers are usually treated with chemotherapy and/or radiation to destroy the tumor cells. However, an unfortunate side-effect of these treatments is pain and ulcers in the mouth due to breakdown of normal protective responses. Light has various applications in human health and normal physiology. Two good examples are vision and sunlight-Vitamin D for bone and health. The use of low dose light to alleviate pain or inflammation and promote tissue healing is termed Photobiomodulation (PBM) Therapy. This treatment can be provided with lasers or LED devices at specific wavelength (color) and dose (power). This treatment is currently being provided by a health care provider - usually a laser - either nurse or dentist prior or during the cancer treatments. There are several exciting innovation where take-home, self-use devices are becoming available.

What are the main findings? Response: The study of oropharyngeal cancer treatment cost was initiated by the Head and Neck Cancer Surgery Department at the University of Texas MD Anderson Cancer Center as part of a larger study of the economic and health consequences of human papillomavirus (HPV) related conditions in Texas.  State specific information is required for policy-makers to consider future investments in cancer prevention based on HPV immunization and cancer screening.  The cost estimates at $140,000 per case for the first two years of treatment are substantially higher than previous estimates.  They indicate the potential savings associated with cancer prevention and partially justify increased investment in immunization efforts.

MedicalResearch.com Interview with: [caption id="attachment_36432" align="alignleft" width="200"]Steven Habbous MSc, PhD candidate Ontario Cancer Institute Scarborough, Ontario, Canada Steven Habbous[/caption] Steven Habbous MSc, PhD candidate Ontario Cancer Institute Scarborough, Ontario, Canada MedicalResearch.com: What is the background for this study? Response: Human papillomavirus (HPV) is a strong risk factor for oropharyngeal cancers (a subset of head and neck cancers). Because HPV-related oropharyngeal cancers generally respond well to treatment and may be prevented through HPV vaccination, it is critical to be able to accurately estimate the incidence and prevalence of this disease. Only recently, however, has testing for HPV become routine at most cancer centres across Canada.  As a result, attempts to estimate the growth of HPV-related oropharyngeal cancer over time may be inaccurate.

MedicalResearch.com Interview with: [caption id="attachment_29579" align="alignleft" width="188"]Michelle M. Chen, MD/MHS Department of Otolaryngology- Head and Neck Surgery Stanford University Dr. Michelle Chen[/caption] Michelle M. Chen, MD/MHS Department of Otolaryngology- Head and Neck Surgery Stanford University  MedicalResearch.com: What is the background for this study? What are the main findings? Response: The benefit of post-operative radiotherapy (PORT) for patients with T1-T2 N1 oral cavity and oropharyngeal cancer without adverse pathologic features is unclear. Starting in 2014, the national guidelines no longer recommended consideration of post-operative radiotherapy for N1 oropharyngeal cancer patients, but left it as a consideration for N1 oral cavity cancer patients. We found that post-operative radiotherapy was associated with improved survival in both oral cavity and oropharyngeal cancers, particularly in patients younger than 70 years of age and those with T2 disease.
Author Interviews, Cancer Research, Smoking, University of Pennsylvania / 01.04.2013

MedicalResearch.com Author Interview: Dr. Steven A. Branstetter, PhD The Pennsylvania State University, 315 E. HHD, University Park, PA 16810.Dr. Steven A. Branstetter, PhD The Pennsylvania State University, 315 E. HHD, University Park, PA 16810. MedicalResearch.com: What are the main findings of the study? Dr. Branstetter: This study demonstrated that the time to the first cigarette of the day after waking is associated with increased levels of a NNAL, a metabolite of a powerful tobacco-specific carcinogen, NNK -- even after controlling for the total number of cigarettes smoked per day. For years, the time to the first cigarette of the day after waking was one of several questions assessing nicotine dependence on the Fagerstrom Test for Nicotine Dependence (FTND), the gold standard questionnaire int he field. Over time, it was found that much of the predictive validity of the FTND was due to the time to first cigarette item. Researchers have found that single time to first cigarette item was highly correlated with other measures of nicotine dependence, and was predictive of more difficulty quitting smoking and increased intake of nicotine. Our current study demonstrates that this behavioral measure, is predictive of exposure to the cancer-causing components of cigarettes, regardless of the total number of cigarettes smoked per day. The results suggest that researchers, clinicians and smokers can assess the level of nicotine dependence and potential cancer risk by looking at the time to the first cigarette of the day after waking.
