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 [...]

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 = [...]

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 [...]

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 [...]

Vaccine clears some precancerous cervical lesions in clinical trial

Source: www.sciencedaily.comAuthor: Mark L Bagarazzi, MD et al. Scientists have used a genetically engineered vaccine to successfully eradicate high-grade precancerous cervical lesions in nearly one-half of women who received the vaccine in a clinical trial. The goal, say the scientists, was to find nonsurgical ways to treat precancerous lesions caused by HPV. "Every standard therapeutic option for women with these lesions destroys part of the cervix, which is particularly relevant for women of childbearing age, who may then be at risk for preterm birth due to a weakened cervix," says Cornelia Trimble, M.D., professor of gynecology and obstetrics, oncology, and pathology at the Johns Hopkins University School of Medicine, and first author of the new report, which appears online Sept. 17 in The Lancet. "A vaccine able to cure precancerous lesions could eventually be one way women can avoid surgery that is invasive and can also harm their fertility." High-grade cervical lesions, termed CIN2/3, occur most often in women 40 or younger, according to Trimble, a member of Johns Hopkins' Kelly Gynecologic Oncology Service and Kimmel Cancer Center. Because the lesions can progress to cancer, they are usually removed by surgery, freezing or laser. The procedures are successful in removing the precancerous areas in approximately 80 percent of women, says Trimble. Less troublesome lesions, called low-grade dysplasia, are usually monitored by physicians rather than immediately removed because they pose less of a risk for cancer and usually regress on their own. For the study, the scientists used a vaccine, originally developed [...]

Raising awareness at the rodeo

Source: www.dailyrecordnews.comAuthor: Nicole Klauss A rodeo barrel racer from California is helping spread the word in Ellensburg that people shouldn’t start using tobacco. Carly Twisselman competed at the Ellensburg Rodeo slack Thursday night. She also helped share the message of the Oral Cancer Foundation, which is “Be smart. Don’t start.” While attending and competing at rodeo events, Twisselman reaches out to youth to encourage them not to pick up the habit they may see their rodeo heroes have. “The rodeo is known for having a lot of chewing tobacco. … The rodeo is such a small community and the heroes in it, the children look up to,” Twisselman said. “When they see their hero, growing up they think ‘I want to be like them.’” Campaign The Oral Cancer Foundation teamed up with Twisselman and bareback bronc rider Cody Kiser to spread the word in the rodeo circuit. The goal of the campaign is to spread awareness of oral cancer and the dangers of starting tobacco use. Twisselman often spends time talking to children and hands out buttons and bandannas to spread the message. Smokeless/spit tobacco is one of the historic causes of deadly oral cancers, and is more addictive than other forms of tobacco use, according to a news release from the Oral Cancer Foundation. According to the Oral Cancer Foundation’s website (www.oralcancer ocw.upc.edu.org), mouth cancers are newly diagnosed in about 115 people each day in the U.S., and worldwide new mouth cancer cases exceed 450,000 annually. When found at [...]

An HPV-E6/E7 immunotherapy plus PD-1 checkpoint inhibition results in tumor regression and reduction in PD-L1 expression

Source: www.nature.comAuthor: A E Rice, Y E Latchman, J P Balint, J H Lee, E S Gabitzsch and F R Jones We have investigated if immunotherapy against human papilloma virus (HPV) using a viral gene delivery platform to immunize against HPV 16 genes E6 and E7 (Ad5 [E1-, E2b-]-E6/E7) combined with programmed death-ligand 1 (PD-1) blockade could increase therapeutic effect as compared to the vaccine alone. Ad5 [E1-, E2b-]-E6/E7 as a single agent induced HPV-E6/E7 cell-mediated immunity. Immunotherapy using Ad5 [E1-, E2b-]-E6/E7 resulted in clearance of small tumors and an overall survival benefit in mice with larger established tumors. When immunotherapy was combined with immune checkpoint blockade, an increased level of anti-tumor activity against large tumors was observed. Analysis of the tumor microenvironment in Ad5 [E1-, E2b-]-E6/E7 treated mice revealed elevated CD8+ tumor infiltrating lymphocytes (TILs); however, we observed induction of suppressive mechanisms such as programmed death-ligand 1 (PD-L1) expression on tumor cells and an increase in PD-1+ TILs. When Ad5 [E1-, E2b-]-E6/E7 immunotherapy was combined with anti-PD-1 antibody, we observed CD8+ TILs at the same level but a reduction in tumor PD-L1 expression on tumor cells and reduced PD-1+ TILs providing a mechanism by which combination therapy favors a tumor clearance state and a rationale for pairing antigen-specific vaccines with checkpoint inhibitors in future clinical trials. *This news story was resourced by the Oral Cancer Foundation, and vetted for appropriateness and accuracy.

Boston votes to ban chewing tobacco from ballparks, including Fenway

Source: www.washingtonpost.comAuthor: Marissa Payne Baseball in Boston is about to change. On Wednesday, the City Council voted unanimously to make its baseball parks and stadiums, including historic Fenway, tobacco-free zones. And yes, the ordinance covers the kind of tobacco you chew, a longtime favorite of many MLB players. “This action will save lives by reducing the number of young people who begin to use smokeless tobacco because they followed the example of the Major Leaguers they idolize,” Matthew Myers, president of the Campaign for Tobacco-Free Kids said in a statement sent to The Washington Post. “We thank Mayor Marty Walsh, the City Council and Boston’s health community for their leadership on this important issue.” Red Sox owner John Henry was also supportive of the legislation. “It’s a great thing,” Henry said (via Boston.com) when Mayor Walsh first proposed the legislation last month. “I’m very supportive.” The ban doesn’t just apply to players, but also fans, and it covers all stadiums from major-league to organized amateur games. Those found in violation of the ordinance face a $250 fine, Boston’s Fox affiliate reports. Boston is now the second major U.S. city to ban tobacco at its baseball stadiums. San Francisco, which banned the substance in April, was the first. Both cities had very good reasons to nix the chew. Smokeless tobacco, like cigarettes, contains the addictive substance nicotine and its users can become more at-risk for illnesses such as cancer, gum disease and heart disease, according to the Mayo Clinic. “You can call chewing tobacco by [...]

Rodeo Competitor Speaks to Youth to Spread Anti-Tobacco Message

Source: www.prnewswire.comAuthor: Oral Cancer Foundation Cody Kiser prepares for competition while sporting the Oral Cancer Foundation's message - Be Smart. Don't Start. NEWPORT BEACH, Calif., Aug. 14, 2015 /PRNewswire-USNewswire/ -- The traditional image of the American cowboy is one of strength, rugged determination and courage. In the world of professional rodeo competition, that image is no different. Cowboys—and increasingly so cowgirls—are held in esteem and looked at as heroes by young and old alike. The power of the cowboy as a compelling figure has not gone unnoticed by the tobacco industry, whose marketing campaigns have sought to tie the ideals of the cowboy with the use of their products. The western/rodeo environment in the US has had a long-term relationship with tobacco, and until 2009 The Professional Rodeo Cowboys Association (PRCA) and the rodeos that they sanctioned had a lengthy history of tobacco money funding the sport. While that has ended at PRCA events, tobacco use and smokeless/spit tobaccos are still popular within the sport. The Oral Cancer Foundation (OCF) believes that in order to solve problems you must engage the problem at the source. As a small and growing non-profit, OCF is not afforded the luxury of relying on conventional methods of outreach utilized by larger, more established charities. To enact meaningful change and bring awareness to the public, OCF must employ ingenuity and creativity to address the problems at hand. Within the world of professional rodeo, that problem remains to be the glorification and pervasive use [...]
