Martin Duffy, 70; Marathon fixture went extra mile

Source: Boston.com By: Bryan Marquard The morning he died, during what turned out to be his last hour or so of life, Martin Duffy got up and ran through his daily regimen of stretching, push-ups, and sit-ups. Several months before, cancer had kept him from adding to his extraordinary streak of 40 consecutive Boston Marathons, but he was used to forging ahead when his body said stop. Take one particular Marathon, probably his 26th. Afterward, he learned he had competed with a broken foot. Realizing at the 2-mile mark that something was amiss, “I divided that race into sections of 6 miles, with each segment a challenge to get through,’’ he told the Globe in 2000. “And somehow I did.’’ In 2009, Mr. Duffy’s string of consecutive completed Boston Marathons was recorded as the third-longest in history when he ran his 40th and final race a few months after being diagnosed with tongue cancer induced by the human papilloma virus. He was 70 when he died Nov. 29 in his Belmont home. Runners often sought advice from Mr. Duffy, given his experience, and he didn’t stop at simply offering tips on how and where to train. An economist who advised businesses and helped them develop strategies, he was still in touch with friends and clients in his final days. “He went in to work the week before he passed away,’’ said his wife, Rusty Stieff. And that was after treatment had left Mr. Duffy no longer able to speak. Instead, he [...]

How protein made by HPV thwarts protective human protein, causing malignancy

Source: American Society for Biochemistry and Molecular Biology BETHESDA, MD., Jan. 11, 2011 – An international team of researchers is reporting that it has uncovered new information about human papilloma virus that one day may aid in the development of drugs to eliminate the cervical-cancer-causing infection. Led by researcher Per Jemth of Uppsala University in Sweden, the collaborators from four institutions detail in the Journal of Biological Chemistry how an offensive protein generated by the sexually transmitted virus handicaps a defensive protein made by the human body. Co-author Neil Ferguson, a biophysicist at University College Dublin, says: "It has proved difficult to stem the proliferation of many viruses using conventional drug discovery. Inhibitors of protein-protein interactions, as in HPV's case, are potentially potent ways to perturb viral infections." There are almost 200 strains of HPV, dozens of which are transmitted through genital contact, and about half of sexually active people have had one or more infections. The immune system eliminates the virus within two years in about 90 percent of cases, according to the Centers for Disease Control and Prevention in Atlanta, but it lingers for many years in a minority of cases. Some strains result in no visible symptoms, others cause genital warts and still others cause cancer. "Infection by high-risk human papilloma viruses is causing as many as half a million cases of cervical cancer and more than 200,000 deaths among women per year, making it one of the most common forms of cancer," Jemth emphasized. For the [...]

Cost of living and the late effects after cancer treatments

Source: Cure Today Author: Kathy Latour Cancer patients are living longer, but if radiation was part of their treatment, late effects may be a problem. Sam LaMonte, MD, knew he had cancer as soon as he touched the lump in his neck. It was 1991, and LaMonte, a head and neck surgeon in Pensacola, Florida, had just stepped down as the president of the Florida division of the American Cancer Society (ACS). “I told my partners I thought it was cancer, and they were in complete denial,” he recalls. “I wasn’t, because I had been feeling cancer in people’s necks my whole life.” LaMonte was right. A biopsy revealed cancer; the primary site was found at the base of his tongue. The diagnosis: stage 3 squamous cell head and neck cancer. The treatment: radiation twice a day for eight weeks. LaMonte, 50, resumed his career three months after he finished treatment. He picked up where he left off with the ACS, joining the national board and becoming the ACS poster boy for survivor issues even after he retired in 2002. Then in 2004, his doctor discovered from an X-ray that LaMonte’s left carotid artery was 100 percent blocked, and the right was 60 percent blocked. The damage, his doctor said, was the result of radiation that had saved his life 15 years earlier. LaMonte was a stroke waiting to happen. He had never had a symptom. “I was dumb as a door,” LaMonte says in retrospect. “So was my radiation oncologist [...]

Aspirin Cuts Death Rate From Several Common Cancers

Source: Web MD Taking aspirin over a long period of time can substantially cut the risk of dying from a variety of cancers, according to a study showing that the benefit is independent of dose, gender, or smoking. It also found that the protective effect increases with age. The study is by Peter Rothwell, MD, PhD, FRCP, of John Radcliffe Hospital in Oxford, England, and colleagues, and has been published online by the journal the Lancet. A previous study by the same authors showed that low doses of aspirin (75-300 milligrams) reduced the number of cases of colorectal cancer by a quarter and deaths caused by the disease by more than a third. The latest study confirms the earlier results and concludes that similar effects can be shown for other types of cancers. The study looked at eight trials examining the effects of a daily dose of aspirin on preventing heart attacks involving 25,570 patients, 674 of whom died from cancer. They showed a 21% reduction in the number of deaths caused by cancer among those who had taken aspirin, compared with people who had not. The investigation also showed that the benefits of taking aspirin increased over time. After five years, death rates were shown to fall by 34% for all cancers and by 54% for gastrointestinal cancers. Participants were also followed up after 20 years, by which point 1,634 of the original participants had died as a direct result of cancer. This 20-year follow-up established that the risk [...]

Late-stage cancer detection in the USA is costing lives

Source: The Lancet In the USA, cancer is the most common cause of death in people aged between 49 and 80 years. In 2007, 562 875 cancer deaths were reported, which account for about 23% of all deaths. Cancers of the lung, colorectum, breast, and prostate are the most common and have the highest mortalities. In high-income countries remarkable progress has been made in cancer management and care, and although cancer incidence continues to rise, due to the influences of ageing, lifestyle, and population growth, mortality has fallen and survival rates are improving for several cancers, largely because of advances in screening, early detection, and treatment. So in light of this progress, the US Centers for Disease Control and Prevention (CDC) report published last week makes for troubling reading, showing as it does that almost half of colorectal and cervical cancers and a third of breast cancers are being diagnosed at a late stage when treatment is less effective. The study is the first nationwide examination of stage-specific cancer incidence rates and screening prevalence for breast, cervical, and colorectal cancer by demographics including age and race or ethnic origin. The study found a lower uptake of screening and the presentation of symptoms late in low-income and ethnic minority communities, who also had longer delays in getting their diagnosis and treatment after an abnormal test. All these factors have been well documented to be associated with a late diagnosis for over a decade, so it is disappointing to see that cancer care [...]

Pertussis reaches epidemic proportions in California; New links identified between vaccine-preventable infections and cancer.

Source: Disabled World New data from the Centers for Disease Control and Prevention (CDC) show that adults remain largely unvaccinated against preventable infectious illnesses. At a news conference convened today by the National Foundation for Infectious Diseases (NFID), experts in public health, infectious disease, oncology and other medical specialties discussed the data and the health consequences for adults who skip vaccines. They collectively called on all adults and health care providers to improve vaccination rates. "For more than six decades, vaccines have protected us from infectious illnesses that have a wide range of consequences, from lost work days and inability to meet our daily obligations, to pain, discomfort, hospitalization, long-term disability and death," said Susan J. Rehm, M.D., NFID medical director. According to Dr. Rehm, by foregoing needed vaccines, adults not only leave themselves vulnerable to sickness, but they expose those around them to unnecessary risks, too. This problem is evident right now, as pertussis (whooping cough) continues to claim the lives of infants in California, while adults, who are frequently responsible for transmitting the disease to infants, fail to get the one-time pertussis booster vaccine. The impact of other vaccine-preventable infections may not be as immediately apparent, but they are no less important. Other vaccines for adults protect against viruses that cause several types of cancer, reactivation of the chickenpox virus that causes shingles later in life, and infection with bacteria that are the leading cause of community-acquired pneumonia. New survey results from NFID suggest that doctor/patient communication challenges may [...]

Snus smokeless tobacco: Less harmful than cigarettes, but not safe.

Source: WebMD By: Daniel J. DeNoon If you use snus, do you win or lose? Snus -- alternately pronounced snoose or snooze -- is a smokeless, flavored tobacco product very different from snuff. When placed between cheek and gum, it doesn't make you spit. Even its critics admit that snus is less harmful than other forms of smokeless tobacco. And it is far less harmful than cigarette smoking. So is snus a good thing? It would be a good thing if everyone who smoked cigarettes or dipped snuff switched to snus instead. It would be a good thing if snus were a way station on the road to quitting all forms of tobacco. It would even be a good thing if kids who would have become smokers became snus users instead. But despite all of that, mounting evidence suggests snus isn't a good thing -- and may be far worse than they appear. Snus: Less Harmful, But Not Safe Cigarettes are the world's most efficient nicotine delivery device. They are also the most deadly. Many of the most dangerous byproducts of cigarettes are created during the burning process. Smokeless tobacco products obviously don't burn. But smokeless tobacco is a major cause of oral cancer, pancreatic cancer, and esophageal cancer. Much of this risk comes from cancer-causing chemicals called nitrosamines and polycyclic aromatic hydrocarbons (PAH). And snuff products actually deliver more cancer-causing nitrosamines than cigarettes do. But nitrosamine content is far lower in snus than in snuff, says Stephen S. Hecht, [...]

Implant survival rate after oral cancer therapy: A review.

Source: HighWire, Stanford University The overall impression regarding the success of dental implants (DI) in patients having undergone oral cancer therapy remains unclear. The aim of the present review study was to assess the implant survival rate after oral cancer therapy. Databases were explored from 1986 up to and including September 2010 using the following keywords in various combinations: "cancer", "chemotherapy", "dental implant", "oral", "osseointegration", "radiotherapy", "surgery" and "treatment". The eligibility criteria were: (1) original research articles; (2) clinical studies; (3) reference list of pertinent original and review studies; (4) intervention: patients having undergone radio- and chemotherapy following oral cancer surgery; and (5) articles published only in English. Twenty-one clinical studies were included. Results from 16 studies reported that DI can osseointegrate and remain functionally stable in patients having undergone radiotherapy following oral cancer surgery; whereas three studies showed irradiation to have negative effects on the survival of DI. Two studies reported that DI can osseointegrate and remain functionally stable in patients having undergone chemotherapy. It is concluded that DI can osseointegrate and remain functionally stable in patients having undergone oral cancer treatment.

Government Certified: What’s Causing Cancer — Research Summary

CANCER-INSIDE AND OUT: Cancer is one of the most prominent diseases in the world. According to the National Cancer Institute, "cancer is a renegade system of growth inside the human body. The changes that must occur inside for cancer to flourish are genetic changes, but factors outside the body also play a role." Outside factors, such as: diet, smoking, alcohol use, hormone levels, and even exposure to certain chemicals and viruses over time, can all work together to create defects and maturation in cells. Furthermore, they go on to explain that environmental, in science, means, everything outside the body, in the environment, that enters and interacts with it. This type of exposure can also include things such as: sunshine, rain, water, food intake, and workplace environment. Researchers have concluded approximately 67 percent of all cancers are due in some part to the environment. Feeling like you can't go anywhere now without being faced with cancer? The good news is these risks can decrease significantly if lifestyle changes are made. The National Cancer Institute suggests about one third of all cancer deaths could have been prevented if lifestyle changes were made, such as avoiding or completely eliminating tobacco and alcohol use. NOT JUST ON THE OUTSIDE: Environmental factors are not the only culprit when it comes to cancer. A lot of cancer is gene related and based on our composition from within. Random gene changes occurring now, as well as gene changes that occur from cell growth and division, accumulate and [...]

Cancer answer? Researchers are working on a more individual approach to each tumour

Source: macleans.ca By: Kate Lanau This summer, Vancouver cancer researchers announced a medical first. Presented with an extremely rare case of tongue cancer—it was so unusual there were no standard treatments to use—they sequenced the DNA of the patient’s tumour, and discovered similarities with another cancer (renal cell carcinoma, a type of kidney cancer) for which there’s a known therapy. The patient received drugs tailored to these results, and the cancer stopped growing for several months. Steven Jones, a molecular biologist with the B.C. Cancer Agency Genome Sciences Centre and one of two lead researchers on the study, calls it a breakthrough. It isn’t standard in hospitals to genetically sequence a patient’s tumour, but “the goal would be, maybe in 10 years, this would be routine,” he says. Dr. Leif Ellisen, an associate professor of medicine at Harvard Medical School, is working to bring tumour genotyping from the lab into the clinic. He and a team have designed a system that can screen relatively large numbers of patients for a variety of mutations across different cancer genes. These genetic mutations are a tumour’s “Achilles’ heel,” noted a recent editorial in the journal EMBO Molecular Medicine. “Every tumour has a flaw,” says Ellisen, who’ll be discussing his work as part of the Scienta Health Series in Toronto on Oct. 7, and his goal is to find it. It’s the mantra of a growing number of researchers, who tout personalized medicine—treatments tailored to each individual—as the future of cancer care. Traditionally, cancer treatment [...]
