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 [...]

Support HPV Vaccination to protect children in the US

Source: www.usatoday.com Author: Liz Sbazo The USA is failing to protect children from preventable cancers that afflict 22,000 Americans a year by not vaccinating enough of them against HPV, a new report says. Although a safe and effective HPV vaccine has been available for eight years, only one-third of girls have been fully immunized with all three recommended doses, according to a report from the President's Cancer Panel, which has advised the White House on cancer since 1971. HPV, or human papillomavirus, is a family of viruses that causes cancer throughout the body, including cancers that predominantly affect men, such as a type of throat cancer. Only 7% of boys are fully vaccinated, although the Centers for Disease Control and Prevention has recommended the shots for them since 2011. Raising vaccination rates to at least 80% of teen girls could prevent 53,000 future cases of cervical cancer in girls alive today, according to the CDC. "Our children deserve this protection," says panel chairperson Barbara Rimer, a professor at the University of North Carolina at Chapel Hill. Administering the HPV shot poses practical difficulties not faced by other adolescent vaccines, because it currently requires three doses, at least two months apart, beginning when kids are 11 or 12, says pediatrician Mary Anne Jackson, director of infectious diseases at Children's Mercy Hospital & Clinics in Kansas City, Mo., who wasn't involved in the new report. Although emerging research suggest that two doses could be equally effective, experts have not yet changed their [...]

Where Do the Millions of Cancer Research Dollars Go Every Year?

Posted: Thursday, Feb. 7, 2013, at 5:18 PM ET By: Quora Contributor Source: Slate.com This question originally appeared on Quora. Answer by David Chan, MD, Oncologist : I'll be the first to admit that despite all the billions put into cancer research, the end results of preventing cancer and treating advanced cancer have been disappointing. Unlike reducing deaths from heart attacks and stroke, progress in reducing deaths from cancer has been disappointingly slow. Sure, we've had our breakthrough drugs like Gleevec, the targeted drug for chronic myelogenous leukemia, and Herceptin for a certain type of breast cancer. But for a lot of other cancers, the treatments aren't giving us bang for the buck. Spending $100,000 to $200,000 a year to extend life for an additional three to six months may be very important to those individuals with cancer, but are a very poor return on investment for society. It's not sustainable, and that's why a lot of national health care programs won't pay for drugs like Avastin, Sutent, Yervoy, and Provenge. Dr. Margaret Cuomo (sister of New York Gov. Andrew Cuomo) recently wrote about her perspective about this. On the amount spent on cancer research: "More than 40 years after the war on cancer was declared, we have spent billions fighting the good fight. The National Cancer Institute has spent some $90 billion on research and treatment during that time. Some 260 nonprofit organizations in the United States have dedicated themselves to cancer — more than the number established [...]

Throat Cancer and HPV – the researcher

6 February, 2013 12:26PM AEDT By Carol Duncan (ABC Local) Source: abc.net.au Assoc Prof Karen Canfell is a researcher with the Lowy Cancer Research Centre at the University of NSW. HPV is her area of expertise. What does she want us to know about HPV and the vaccination program? CAROL DUNCAN: Karen, your area of expertise is human papilloma virus and I understand there's not just one but 100 or more? ASSOC PROF KAREN CANFELL: That's right, there's a large number of types HPV that have been implicated in cancer but it's really two of those types that are responsible for the vast majority of cancers, HPV 16 & 18 and those types are the ones that are included in the vaccine that is now available to us. CAROL DUNCAN: I guess this is the point of this series this week is that we now have another cancer which is, in essence, preventable. ASSOC PROF KAREN CANFELL: Yes, I think what we're seeing with HPV is an incredible success story in cancer prevention. This started with the vaccination of girls and women in Australia. Because HPV has a very important role in cervical cancer and, in fact HPV is responsible for virtually all cervical cancers, the types we just mentioned (types 16 & 18) are responsible for about 70% of those cancers. Five years ago, in 2007, we had the implementation of the National HPV Vaccination Program in girls and women in Australia and that's really had incredible effects [...]

Discovery may help scientists boost broccoli’s cancer-fighting power

Source: University of Illinois College of Agricultural, Consumer and Environmental Sciences URBANA – A University of Illinois study has shown for the first time that sulforaphane, the powerful cancer-fighting agent in broccoli, can be released from its parent compound by bacteria in the lower gut and absorbed into the body. "This discovery raises the possibility that we will be able to enhance the activity of these bacteria in the colon, increasing broccoli's cancer-preventive power," said Elizabeth Jeffery, a U of I professor of human nutrition. "It's also comforting because many people overcook their broccoli, unwittingly destroying the plant enzyme that gives us sulforaphane. Now we know the microbiota in our digestive tract can salvage some of this important cancer-preventive agent even if that happens," she said. Although scientists had long theorized that the intestinal microbiota could perform this trick, no one knew it for certain. Now Jeffery and U of I colleagues Michael Miller and Ren-Hau Lai have proved it by injecting glucoraphanin, the parent compound for sulforaphane, into the ligated lower gut of rats and demonstrating that sulforaphane is present in blood from the mesenteric vein, which flows from the gut to the liver. "The presence of sulforaphane in measurable amounts shows that it's being converted in the lower intestine and is available for absorption in the body," Jeffery said. The cecum, the part of the rat's lower gut into which the scientists infused the glucoraphanin, houses bacteria that aid in digestion and metabolism, similar to the human colon. [...]

Medicines to deter some cancers are not taken

Source: www.nytimes.com Author: Gina Kolata Many Americans do not think twice about taking medicines to prevent heart disease and stroke. But cancer is different. Much of what Americans do in the name of warding off cancer has not been shown to matter, and some things are actually harmful. Yet the few medicines proved to deter cancer are widely ignored. Take prostate cancer, the second-most commonly diagnosed cancer in the United States, surpassed only by easily treated skin cancers. More than 192,000 cases of it will be diagnosed this year, and more than 27,000 men will die from it. And, it turns out, there is a way to prevent many cases of prostate cancer. A large and rigorous study found that a generic drug, finasteride, costing about $2 a day, could prevent as many as 50,000 cases each year. Another study found that finasteride’s close cousin, dutasteride, about $3.50 a day, has the same effect. Nevertheless, researchers say, the drugs that work are largely ignored. And supplements that have been shown to be not just ineffective but possibly harmful are taken by men hoping to protect themselves from prostate cancer. As the nation’s war on cancer continues, with little change in the overall cancer mortality rate, many experts on cancer and public health say more attention should be paid to prevention. But prevention has proved more difficult than many imagined. It has been devilishly difficult to show conclusively that something simple like eating more fruits and vegetables or exercising regularly helps. [...]

U.S. cancer death rates continue to fall

Source: www.ajc.com Author: staff Some 650,000 people are alive today who wouldn't be were it not for advances in cancer prevention, detection and treatment over the past 15 years, new statistics show. The American Cancer Society's Cancer Statistics 2009 report finds an encouraging 19.2 percent drop in cancer death rates among men from 1990 to 2005, as well as an 11.4 percent drop in women's cancer death rates during the same time period. Overall, cancer death rates fell 2 percent per year from 2001 to 2005 in men and 1.6 percent per year from 2002 to 2005 in women. By comparison, between 1993 and 2001, overall death rates in men declined 1.5 percent per year and, between 1994 and 2002, 0.8 percent in women. "We continue to see a decrease in death rates from cancer in both men and women and this is mainly because of prevention - mostly a reduction in smoking rates; detection which includes screening for colorectal cancer, for breast cancer and for cervical cancer; and also improved treatment," said report author Ahmedin Jemal, strategic director for cancer surveillance at the American Cancer Society. "To put this in perspective, the number of lives saved is more than the population of Washington, D.C.," said Dr. Louis M. Weiner, director of the Lombardi Comprehensive Cancer Center at Georgetown University. "In my mind, that's a cause for some celebration. However, there are some sobering trends that we have to be aware of. The death rate for cardiovascular disease has dropped [...]

Nutrition and cancer

Source: insciences.org Author: Relatively recently, researchers have become keenly interested in exploring which food compounds are beneficial in treating and preventing serious diseases such as cancer and osteoporosis. Omer Kucuk, MD, is one of those researchers. Kucuk, a professor of hematology and medical oncology at Emory Winship Cancer Institute, studies specific food compounds and their effect on cancer prevention and treatment. Evidence indicates that some food compounds, such as soy isoflavones and curcumin, can increase the effectiveness of chemotherapy and radiation therapy. To listen to Kucuk's own words about which food compounds affect cancer prevention and treatment, access Emory's new Sound Science podcast at http://whsc.emory.edu/soundscience/. Kucuk conducted the first clinical trials to show the benefits of soy and lycopene supplements in prostate cancer treatment. "In our preclinical studies we have observed that taking soy isoflavones during chemotherapy and radiation for advanced prostate cancer can improve the efficacy of the treatments," says Kucuk. "The compounds sensitize the cancer cells to chemotherapy and radiation while at the same time they protect the normal tissues from side effects." Most nutritional compounds used for therapy or disease prevention can be taken as part of a routine diet and have little if any side effects, Kucuk says. "People can get enough lycopene by eating tomato paste and tomato sauce, which is very rich in lycopene. So, if people ate a couple of ounces of tomato paste a day as part of a regular diet, they would eat enough to get all the benefits," he says. [...]
