ACS awards $1.7M to study racial disparities in HNC patients

Source: http://www.drbicuspid.com/ Author: DrBicuspid Staff The American Cancer Society (ACS) has awarded a $1.7 million grant to Philadelphia researchers to investigate factors that may contribute to the racial disparities seen among those diagnosed and treated for head and neck cancers (HNC) -- specifically head and neck squamous cell carcinoma (HNSCC). While head and neck cancers account for only 3% of all cancers in the U.S., a disproportionately high number of African Americans are affected. Recent research has shown that other biological factors, and tobacco and alcohol use, may have a role in the development of these cancers. Other studies suggest that low socioeconomic status and poor healthcare access are the main contributors to this disparity. "Studies on genes involved in tobacco and drug metabolism and efflux suggest an association of genetic variants with head and neck cancer risk and survival in populations of European and Asian ancestries," stated Camille Ragin, PhD, an associate professor at the Fox Chase Cancer Center and the study's principal investigator, in a press release. "Genetic variants associated with the survival disparity of head and neck cancer in African-derived populations, however, is not yet clear." An accumulation of cancer-causing compounds occurs when products from tobacco smoke enter the body's cells, in some cases enabled by alcohol, and are broken down by proteins. Variations in the genetic code that generate these proteins can lead to differences in their function and could affect the way disease may develop or respond to drug therapy. In many cases, the genetic [...]

Researchers find way to diagnose aggressiveness of oral cancer

Source: www.news-medical.net Author: staff Studying mouth cancer in mice, researchers have found a way to predict the aggressiveness of similar tumors in people, an early step toward a diagnostic test that could guide treatment, according to researchers at Washington University School of Medicine in St. Louis. "All patients with advanced head and neck cancer get similar treatments," said Ravindra Uppaluri, MD, PhD, associate professor of otolaryngology. "We have patients who do well on standard combinations of surgery, radiation and chemotherapy, and patients who don't do so well. We're interested in finding out why." Reporting in Clinical Cancer ResearchK/em>, the investigators found a consistent pattern of gene expression associated with tumor spreading in mice. Analyzing genetic data from human oral cancer samples, they also found this gene signature in people with aggressive metastatic tumors. "We didn't automatically assume this mouse model would be relevant to human oral cancer," said Uppaluri, who performs head and neck surgeries at Barnes-Jewish Hospital. "But it turns out to be highly reflective of the disease in people." Rather than use genetic methods to induce tumors in the mice, the research team repeatedly applied a known carcinogen, in much the same way humans develop cancer of the mouth. "Patients often have a history of tobacco and alcohol use, which drive the development of these tumors," Uppaluri said. "We felt that exposing the mice to a carcinogen would be more likely to produce similar kinds of tumors." The researchers, including first author Michael D. Onken, PhD, research assistant [...]

Prognosis of tumors positive for human papilloma virus in head and neck cancers varies according to the site

Source: www.sciencecodex.com Author: staff Patients with cancer of the throat and who are positive for the Human Papilloma virus (HPV+) have a good prognosis, but until now the effect of being HPV+ on the prognosis of tumours located elsewhere in the head and neck was unknown. Danish researchers have now shown that HPV status appears to have no prognostic effect on the outcome of primary radiotherapy in head and neck cancer outside the oropharynx (the part of the throat located behind the mouth, and which contains the soft palate and the base of the tongue), the ESTRO 33 congress will hear today (Sunday). Presenting her results to the congress, Dr Pernille Lassen, MD, PhD, from the Aarhus University Hospital, Aarhus, Denmark, will say that head and neck cancers located outside the oropharynx should probably not be treated with the less intensive treatment strategies that are currently being investigated in clinical trials for HPV+ oropharyngeal tumours. "HPV status has a very potent prognostic impact in radiotherapy for oropharyngeal cancer, and DNA from HPV has been found in all types of head and neck cancer, although it is far more common in oropharyngeal tumours. We decided to investigate the impact of HPV status in non-oropharyngeal cancers in the DAHANCA database, which includes all Danish head and neck cancer patients," Dr Lassen will say. The researchers searched the database to identify patients with locally advanced cancers who had been treated primarily with radiotherapy, and identified 1606 patients with larynx and pharynx carcinomas. Overall, [...]

Jim Kelly’s toughest game: Fighting oral cancer

Source: www.foxnews.com Author: Dr. Manny Alvarez Jim Kelly, the Hall of Fame quarterback who played for the Buffalo Bills until 1996, is one of the greatest football players that I have ever seen. During his football career, I followed him closely and was always in awe of his athletic abilities, his leadership qualities and his love of family. Unfortunately, Jim Kelly is currently battling a second recurrence of oral cancer and has been scheduled to undergo surgery in an attempt to control the disease. His wife, Jill, told the Associated Press that her 54-year-old husband’s cancer is aggressive and beginning to spread. I’ve been following Jim Kelly’s health struggles and have been thinking about him, praying that he gets better. It is easy to think of some humans as immortal – especially when you’re looking at an individual as physically fit as Jim Kelly. But we tend to forget that sometimes nature has a unique plan for all of us. However, Jim Kelly’s struggles can serve as a reminder for us all to be vigilant about our health. Jim Kelly is suffering from oral cancer, which doesn’t get the attention that it deserves, despite the fact that 42,000 new cases will be diagnosed in 2014, according to the National Cancer Institute. Oral cancers are any cancers occurring in the oral cavity, which starts in your throat and extends all the way to your lips. The sad part about this disease is that oral cancers are typically not identified early, which [...]

Global trends suggest HPV positive oral cancer greatly increased in young males

Source: www.zawya.com Author: staff While the incidence of smoking-related oral squamous cell carcinoma has decreased in many parts of the world, cases of human papilloma virus (HPV) positive oropharyngeal cancer (OPSCC) have greatly increased. Otolaryngologists are finding that the majority of their patients are male and a lot younger in age than their counterparts. This "new" head and neck cancer patient differs in several ways from the "traditional" head and neck cancer patients who were older, had significant tobacco and alcohol exposure, and potential tumours throughout the upper aerodigestive tract. The significance of this global trend suggests that more attention needs to be paid to the phenomena here in the Middle East. Dr Marilene Wang, Professor, Chief of Otolaryngology, UCLA Department of Head and Neck Surgery, will be discussing the increasing incidence of young cancer patients who are non-smokers, but happen to be HPV positive and how these cases should be managed in the Middle East at the 11th Middle East Update in Otolaryngology Conference & Exhibition - Head and Neck Surgery (ME-OTO) from the 20-22 April 2014 at the Madinat Jumeirah Arena, Dubai, UAE. According to Dr Wang, "Currently, the most common head and neck cancer patients are younger, primarily male, and have no or relatively minimal exposures to tobacco and alcohol. Yet, they often have histories of notable increased sexual encounters. Although HPV positive OPSCC demonstrates an alarming increasing incidence, this is balanced by a significant response to treatment regardless of advanced stage. "Cases of OPSCC associated with [...]

New study claims children who use snus before age 16 are more likely to become cigarette smokers

Source: Reuters Health Author: Shereen Jegtvig Norwegians who started using snus before age 16 were more likely to become cigarette smokers than those who started using snus later in life, according to a new study. Snus is moist smokeless tobacco developed in Sweden. It's contained in a small pouch, and unlike regular chewing tobacco, it doesn't make the user spit. Research suggests snus has lower levels of chemicals called nitrosamines than cigarettes and may be less harmful. In Norway, snus has become a smoking cessation aid and most older snus users are former smokers. But snus is also becoming increasingly popular among young Norwegian adults, many of whom have not smoked cigarettes. And although research is divided, the current thinking is that snus use reduces the likelihood of taking up smoking. The authors of the new study wanted to know more about when people start using snus, to see if that ties into whether they also begin smoking cigarettes. "I already knew about the research investigating associations between snus use and later smoking, but discovered that snus debut age had not been mentioned in that research," Ingeborg Lund told Reuters Health in an email. Lund is a researcher with the Norwegian Institute for Alcohol and Drug Research - SIRUS, in Oslo. She and her colleague Janne Scheffels published their study in Nicotine and Tobacco Research. The researchers analyzed surveys of Norwegian teenagers and adults conducted from 2005 to 2011. Out of 8,313 people, 409 were long-term snus users who had started using snus before [...]

Cancer survivors demand picture-based warnings on cigarette labels

Source: www.interaksyon.com Author: staff MANILA, Philippines -- More than 150 anti-smoking activists, including throat cancer survivors, marched to the Commission on Human Rights in Quezon City Thursday to urge government to fast-track the passage of legislation requiring tobacco firms to put graphic health warnings on cigarette packs. The “Right to Health Walk” is the third march organized by New Vois Association of the Philippines to push public health issues to the fore. “Ten percent of the world’s 1.3 billion smokers can be found in Southeast Asia where the Philippines belong. We are the second largest smoking population in this region with 17.3 million adults smoking. More than 87,000 Filipinos die every year because of smoking -- that’s more than the number of those who succumb to heart attack and stroke. This is clear and present danger that must be addressed at the soonest,” Emer Rojas, NVAP president, said. Rojas said graphic health warnings provide a clearer message about the harm smoking causes, especially to women, children, and the poor who are lured to the habit by the attractive designs of cigarette packs. The newly released Tobacco Atlas of the Southeast Asia Tobacco Control Alliance showed the Philippines among the three countries with the most number of smoking women in the region. It is estimated that nine percent of Filipino women smoke. This is statistically more than Indonesia, which has the most number of smokers in the region. Only 4.5 percent of Indonesian women smoke. The Tobacco Atlas also estimates that [...]

Differences in Imaging Characteristics of HPV-Positive and HPV-Negative Oropharyngeal Cancers: A Blinded Matched-Pair Analysis

Source: American Journal of Neuroradiology Please address correspondence to Dr Lawrence E. Ginsberg, Department of Diagnostic Imaging, Unit 1482, University of Texas MD Anderson Cancer Center, 1400 Pressler St, Houston, TX 77030; e-mail: [email protected] Abstract BACKGROUND AND PURPOSE: Human papillomavirus–positive oropharyngeal cancers typically have younger age of onset, limited tobacco exposure, and more favorable prognosis than HPV-negative oropharyngeal cancers. We assessed whether HPV-positive and HPV-negative oropharyngeal cancers have consistent differences in pretreatment imaging characteristics. MATERIALS AND METHODS: A retrospective review of 136 pretreatment CT examinations of paired HPV-positive and HPV-negative oropharyngeal cancers matched for T stage, tumor subsite, and smoking status was performed with the reviewing radiologist blinded to HPV status and clinical stage. Demographic/clinical characteristics and imaging characteristics of primary lesions and metastatic nodal disease were compared by use of Fisher exact testing. The McNemar χ2 test was used for the matched-pair analysis. RESULTS: By imaging, HPV-negative tumors were more likely to demonstrate invasion of adjacent muscle (26% versus 6%, P = .013). HPV-positive primary tumors were more likely to be enhancing and exophytic with well-defined borders, whereas HPV-negative primary tumors were more likely to be isoattenuated and demonstrate ill-defined borders, though these results were not statistically significant. HPV-positive tumors were more likely to demonstrate cystic nodal metastases than HPV-negative tumors (36% versus 9%, P = .002). CONCLUSIONS: In this matched and blinded analysis of the imaging differences between HPV-positive and HPV-negative oropharyngeal cancers, HPV-positive carcinomas often had primary lesions with well-defined borders and cystic nodal metastases, whereas HPV-negative [...]

E-Cigarettes Are in Vogue and at a Crossroads

By LIZ ALDERMANPublished: June 12, 2013Source: NY Times PARIS — On a recent day in the shadow of the Arc de Triomphe, a line of 20 people spilled onto the sidewalk of a trendy new boutique, eager to get a taste of its latest gourmet offerings. Olivia Foiret, the manager of ClopiNette, demonstrates filling an e-cigarette for a client. A sign in the window promoted piña colada as the store’s flavor of the month. A woman wearing a Chanel jacket said she wanted to try peach. But this was no temple of gastronomy. It was one of scores of electronic cigarette shops that have been springing up by the week in Paris as well as in numerous cities across Europe and the United States. Inside the ClopiNette boutique, shoppers can choose from among more than 60 flavors of nicotine liquid — including Marlboro and Lucky Strike flavors — all in varying strengths and arranged in color-coded rows. (ClopiNette is a play on “clope,” French slang for a cigarette.) “It’s like visiting a Nespresso store,” said Anne Stephan, a lawyer specializing in health issues at a nearby law firm. What’s driving her into the store is a desire shared by many: they want to give up smoking tobacco but don’t want to kick the smoking habit. After smoking 20 cigarettes daily for 25 years and failing to quit, Ms. Stephan said she had cut down to one a day in the three months since she began puffing on a so-called e-cig. Using [...]

Oral cancer sneaks up

Source: well.blogs.nytimes.com Author: Donald G. McNeail Jr. and Anahad O'Connor The actor Michael Douglas has done for throat cancer what Rock Hudson did for AIDS and Angelina Jolie did for prophylactic mastectomy. By asserting last week that his cancer was caused by a virus transmitted during oral sex, Mr. Douglas pushed the disease onto the front pages and made millions of Americans worry about it for the first time. In this case, it was a subset of Americans who normally worry more about being killed by cholesterol than by an S.T.D. The typical victim is a middle-aged, middle-class, married heterosexual white man who has had about six oral sex partners in his lifetime. The virus, human papillomavirus Type 16, also causes cervical cancer. So is there any early oral screening that a man can have — an equivalent to the Pap smear, which has nearly eliminated cervical cancer as a death threat in this country? The answer, according to cancer experts and a recent opinion from the United States Preventive Services Task Force, is no. And for surprising reasons. The Pap test — invented in 1928 by Dr. George N. Papanicolaou — involves scraping a few cells from the cervix and checking them under a microscope for precancerous changes. Precancerous cells have a “halo” around the nucleus, while cancerous ones have larger, more colorful nuclei, said Dr. Paul D. Blumenthal, a professor of gynecology at Stanford University Medical School. In theory, it should be similarly easy to scrape and examine [...]
