Manitoba expands HPV vaccination program to include boys

Source: www.rapidnewsnetwork.comAuthor: Cody Griffin While most HPV infections go away over time with no treatment, a few can go on to cause cancer. Health Minister Sharon Blady said the province’s vaccine program will be expanded next year to include Grade 6 and Grade 9 boys as part of Manitoba’s cancer strategy. The province will also be doing a catch-up period in grade 9. About 59 percent of the physicians recommended HPV vaccination more often for adolescents who they perceived to be at higher risk for getting an HPV infection, as opposed to recommending it routinely for all adolescents. “Human papillomavirus can cause abnormal cell changes that can lead to cervical cancer, as well as cancer of the vagina, vulva, penis, anus, mouth and throat”, said Dr. Sri Navaratnam, president and CEO, CancerCare Manitoba. A study in Texas found that a more rigorous, information driven outreach program increased the number of children receiving the vaccine, and other recent studies have reinforced the efficacy of the vaccine to prevent cancer and not promote promiscuity among teenagers. Any girl or boy who misses the vaccine in Grade 6 will be eligible to get it in later years free of charge under the province’s “once eligible, always eligible”, program. But now we know it causes cancer in men as well. Gilkey and colleagues found that 27 percent of physicians across the country reported that they do not strongly endorse HPV vaccination, and 26 percent and 39 percent reported that they do not provide timely recommendations [...]

Less Is More for HPV Oropharyngeal Cancer Reduced-intensity regimen clears disease in 86% of cases

Source: www.medpagetoday.comAuthor: Charles Bankhead SAN ANTONIO -- Less intense treatment of low-risk human papillomavirus (HPV)-related oropharyngeal cancer achieved a high rate of pathologic complete response (pCR) and favorable patient-reported outcomes, a preliminary trial showed. Overall, 37 of 43 (86%) patients achieved pCR with deintensified chemoradiation, including all but one evaluable primary tumor. The pCR rate was virtually identical to historical rates achieved with standard regimens, according to Bhishamjit Chera, MD, of the University of North Carolina (UNC) at Chapel Hill, and colleagues. Selected patient-reported adverse events peaked during the first 6 to 8 weeks and then declined thereafter. About 40% of patients required feeding tubes for a median duration of 15 weeks, but no patients required permanent feeding tubes, they reported here at the American Society for Radiation Oncology meeting. The regimen consists of lower doses of radiotherapy and concurrent cisplatin, administered over 6 weeks. With high-dose therapy, the radiation protocol requires an additional week. "Though we have limited follow-up, the pathological complete response rate with this reduced-intensity chemoradiotherapy regimen is very high in patients with favorable-risk oropharyngeal squamous-cell carcinoma," Chera said. "The early quality-of-life measurements are encouraging, particularly the data on swallowing. We are optimistic that these results with reduced-intensity treatment will translate into good long-term disease control with less toxicity." The study reflects the current trend and momentum in the management of HPV-positive oropharyngeal cancer, said Zain Husain, MD, of Yale Cancer Center in New Haven, Conn. "This is the second study to show that de-escalation of therapy might [...]

Athletes drive increase in high schoolers’ use of smokless tobacco, CDC study shows

Source: www.kyforward.comAuthor: www.kyforward.com web staff High-school athletes are using more smokeless tobacco, even though overall tobacco use among high-school students has declined, according to a study published by the federal Centers for Disease Control and Prevention. We can do more to protect America’s youth from a lifetime of addiction,” Tom Frieden, CDC director, said in a press release. “The fact is, smokeless tobacco products, such as chewing tobacco, snuff or dip, can cause cancer of the mouth, esophagus and pancreas. And the nicotine in these products is harmful to the developing brain. Because we know tobacco-free policies in schools and other public recreational areas work, we must take action now so that our children are safe from these toxins.” Student responses to the national Youth Risk Behavior Survey from 2001 through 2013 show that the share reporting any tobacco use dropped to 22.4 percent from 33.9 percent, and the rate of those smoking combustible tobacco products dropped to 19.5 percent from 31.5 percent. However, those who reported using smokeless tobacco products increased to 8.8 percent from 8.2 percent. The increased use of smokeless tobacco was driven by athletes. The rate among non-athletes remained unchanged at 5.9 percent but has “increased significantly” to 11.1 percent from 10 percent in youth athletes. Researchers suggest that athletes are aware of the adverse consequences of smoking on athletic performance, but may view smokeless tobacco as “less harmful, socially acceptable, or even a way to enhance athletic performance.” The 2013 YRBS found that 26.3 percent [...]

Methods: Women age 18 to 25 years from the CVT were randomly assigned to the HPV16/18 vaccine (Cervarix) or a hepatitis A vaccine. Cervical, oral, and anal specimens were collected at the four-year follow-up visit from 4186 women. Multisite and single-site vaccine efficacies (VEs) and 95% confidence intervals (CIs) were computed for one-time detection of point prevalent HPV16/18 in the cervical, anal, and oral regions four years after vaccination. All statistical tests were two-sided. Results: The multisite woman-level vaccine efficacy was highest among “naïve” women (HPV16/18 seronegative and cervical HPV high-risk DNA negative at vaccination) (vaccine efficacy = 83.5%, 95% CI = 72.1% to 90.8%). Multisite woman-level vaccine efficacy was also demonstrated among women with evidence of a pre-enrollment HPV16 or HPV18 infection (seropositive for HPV16 and/or HPV18 but cervical HPV16/18 DNA negative at vaccination) (vaccine efficacy = 57.8%, 95% CI = 34.4% to 73.4%), but not in those with cervical HPV16 and/or HPV18 DNA at vaccination (anal/oral HPV16/18 VE = 25.3%, 95% CI = [...]

Primack, MD, PhD Associations Between Initial Water Pipe Tobacco Smoking and Snus Use and Subsequent Cigarette Smoking: Results From a Longitudinal Study of US Adolescents and Young Adults Importance Many adolescents and young adults use alternative tobacco products, such as water pipes and snus, instead of cigarettes. Objective To assess whether prior water pipe tobacco smoking and snus use among never smokers are risk factors for subsequent cigarette smoking. Design, Setting, and Participants We conducted a 2-wave national longitudinal study in the United States among 2541 individuals aged 15 to 23 years old. At baseline (October 25, 2010, through June 11, 2011), we ascertained whether respondents had smoked cigarettes, smoked water pipe tobacco, or used snus. At the 2-year follow-up (October 27, 2012, through March 31, 2013), we determined whether baseline non–cigarette smokers had subsequently tried cigarette smoking, were current (past 30 days) cigarette smokers, or were high-intensity cigarette smokers. We fit multivariable logistic regression models among baseline non–cigarette smokers to assess whether baseline water pipe tobacco smoking and baseline snus use were associated with subsequent cigarette smoking initiation and current cigarette smoking, accounting for established sociodemographic and behavioral risk factors. We fit similarly specified multivariable ordinal logistic regression models to assess whether baseline water pipe tobacco smoking and baseline snus use were associated with high-intensity cigarette smoking at follow-up. Exposures Water pipe tobacco smoking and the use of snus at baseline. Main Outcomes [...]

Throat and tongue cancers linked to sexually transmitted virus on the rise

Source: www.theage.com.au Author: Julia Medew The sexual revolution is producing a new wave of throat and tongue cancers among middle-aged people, who are falling victim to a rare side effect of the "common cold of sexually transmitted infections". A growing number of Australians with oropharyngeal cancer are testing positive to the human papillomavirus (HPV), suggesting it has caused their disease rather than smoking or heavy drinking - factors responsible for many head and neck cancers in the past. Oropharyngeal cancer is usually found in the back third of the tongue or the tonsils. In 2014, about 125 Victorians were diagnosed with it. Most were men. An Australian study of 515 patients diagnosed with the condition between 1987 and 2010 found that the proportion of people with an HPV-related diagnosis increased from 20 per cent between 1987 and 1995 to 64 per cent between 2006 and 2010. Over the same period, the proportion of people diagnosed with throat cancer who had never smoked increased from 19 per cent to 34 per cent, suggesting HPV may overtake smoking and drinking as a cause of the cancer in future. American doctors say more oral sex following the sexual revolution of the 1960s probably spread HPV to more people's mouths and throats. Actor Michael Douglas said he believed oral sex was to blame for his HPV-related throat cancer in 2013. But Dr Matthew Magarey​, an ear nose and throat surgeon at Epworth and Peter MacCallum hospitals in Melbourne, said while HPV-related throat cancers were [...]

California to big-league ballplayers: Stop chewing tobacco

Source: apnews.myway.com Author: John Rogers California lawmakers have taken the first step toward accomplishing something Major League Baseball could never do: Stop players from stuffing those big wads of chewing tobacco into their mouths during games. With Gov. Jerry Brown signing a bill earlier this week banning the use of smokeless tobacco in all California ballparks, a practice dating to the days of Babe Ruth and Ty Cobb now seems headed toward the sport's endangered species list. Although California is only one state, it is home to five of Major League Baseball's 30 teams, and team owners themselves have been pressing for a ban for years. Last May they got one in San Francisco, home of the reigning World Series champion Giants. In August they got another in Boston, site of fabled Fenway Park, and when Brown signed Assembly Bill 768 on Sunday one was already in the works for Los Angeles. "Major League Baseball has long supported a ban of smokeless tobacco at the Major League level and the Los Angeles Dodgers fully support the Los Angeles City Tobacco ordinance and Campaign for Tobacco-Free Kids," the Dodgers said in a statement last month. Major League Baseball still needs buy-in from the players, however, because the statewide ban that takes effect before next season has no provision for enforcement. "The question we've been asked is are we going to have police officers walking around checking lips, and no, that's not the case," said Opio Dupree, chief of staff to Assemblyman [...]

SA Developed Melanoma Drug Now Seen Effective in Fighting Lung Cancer

Source: www.woai.comAuthor: News Radio 1200 WOAI Staff  Keytruda, a cancer drug developed largely at San Antonio's START Center, has already proven to be effective in treating advanced melanoma to the point that it is the major part of former President Jimmy Carter's treatment.  Now, News Radio 1200 WOAI reports Keytruda has been given 'fast track' approval by the FDA for use in treating lung cancer, the leading cause of cancer deaths in the United States. Dr. Amita Patnaik, a researcher and oncologist at START who helped develop the drug, says the impact of Keytruda on lung cancer patients has been amazing. "Close to 40% of those patients will receive a response," she said.  "And of those patients who receive a response, about 80% of those patients will have a long term response." The life saving potential of Keytruda in fighting non small cell lung tumors is obvious.  An estimated 221,000 Americans are diagnosed with lung cancer each year, and 158,000 die of the disease annually. Dr. Patnaik says Keytruda is becoming the most successful of what are known as 'targeted therapies,' drugs which trigger the body to take action to fight the cancer.  She says both melanoma and lung cancer work essentially the same way to undermine the body's defenses. "The commonality between melanoma and lung cancer is there is a supressive effect of the cancer on the immune system." She says Keytruda essentially overrides that supressive effect, prompting the body to restart its natural immune defenses and fight the [...]

Research Leader Discusses FDA-Funded Immunotherapy for Head and Neck Cancer

 Source: www.onclive.comAuthor: Gina Columbus  Brett Miles, MD, DDS   The investigational immunotherapy axalimogene filolisbac (ADXS11-001) has emerged as a potentially practice-changing agent in the treatment of HPV-related oropharyngeal cancer. Shown to generate T cells directed against a cancer antigen and neutralize suppressor regulatory T cells and myeloid-derived suppressor cells that protect the tumor microenvironment from an immunologic attack and contribute to tumor growth, ADXS11-001 is the first of its kind—a therapeutic vaccine for the disease. The agent is being examined in an ongoing phase II trial, which was reported as one of 18 recipients of research grants recently awarded by the FDA’s Office of Orphan Product Development. The grants, given to sites for product development in rare diseases, total more than $19 million. The ADXS11-001 grant provides collaborating researchers from Baylor College of Medicine and the Icahn School of Medicine at Mount Sinai with more than $1.1 million over 3 years. Eligible patients for the phase II study are newly diagnosed with stage II to IV HPV16-positive oropharynx squamous cell carcinoma who are scheduled to receive ablative transoral robotic surgery. In an interview with OncLive, the study’s surgical principal investigator, Brett Miles, MD, DDS, associate professor of Otolaryngology Head and Neck Surgery, co-chief, Division of Head and Neck Oncology, Icahn School of Medicine at Mount Sinai, discusses the potential of ADXS11-001 in HPV-associated head and neck cancer and other emerging therapies and treatment strategies.

Patient Support in Oral Cancer: From Sydney to New York to London, survivors and patients interact through an important portal to get through difficult times

Source: www.prnewswire.comAuthor: Press Release NEWPORT BEACH, Calif., Sept. 28, 2015 -- The word "cancer" will incite fear in anyone. When that word comes at the end of a sentence that began with your name, the impact can be life changing. "I had a great job, a beautiful house and a happy family life," recalls oral cancer survivor and Oral Cancer Foundation (OCF) Director of Patient Support Services, Christine Brader. "All that changed once I got sick." Those affected by oral cancer, like Christine, are saddled not only with the physical challenges of treating and surviving the disease, but they must also live with the emotional uncertainty and anxiety that accompanies a diagnosis. OCF's Patient Support Forum (oralcancersupport.org) was created specifically to provide patients with the information, guidance, and support they need to face a cancer diagnosis. Now in its 15th year, it has helped tens of thousands navigate a difficult path. It was nearly 16 years ago that oral cancer survivor and OCF founder Brian Hill began his search for answers. "When I was first diagnosed," Hill recalls, "I was scrambling for the right information. Once inside the treatment world I was faced with decisions about which treatment path was right for me, uncertainties of what would lay ahead, the arrival of complications unexpected, pain, and ultimately a sense of the loss of control and a resulting fear." While hospital support groups and some online chat rooms existed at the time, they fell short of providing the insights, guidance and accessibility necessary [...]
