Overcoming the odds

12/25/2007 Regina,Saskatchewan,Canada Tim Switzer Regina Post Leader (www.canada.com/reginaleaderpost) "Live strong" is more than just a yellow bracelet on Dale Bloom's wrist. It's how the Regina man has been forced to approach his life for the last three years. Bloom was diagnosed with advanced stage oral cancer on Jan. 10, 2005. On Oct. 7 of this year, he finished the Chicago Marathon. "It's like night and day," said Bloom, 46. "I never gave up any hope. Even though the odds weren't that great -- I was told it was a one-in-three shot -- it never crossed my mind that I wasn't the one." As he stood among 44,999 other runners in the starting area of the marathon, Bloom's mind couldn't help but wander to the previous 21/2 years. "There were a lot of people that helped me get to that point," Bloom said, fighting back tears. "It was crazy, but that's who I thought about. I thought about my co-workers, who set up a dance card to each take an hour out of their schedules to come and sit with me at chemotherapy just to take my mind off things. I thought about my son's friends parents, who got together and all organized days of cooking where they brought us food each and every day. My sisters were there from beginning to end. In 2005, I lost my mother and in 2006, I lost my father so I thought about them a lot. "And then I thought about my wife and [...]

Machine ‘may speed up cancer treatment’

12/25/2007 Melbourne, Australia staff news.theage.com.au A state-of-the-art radiation machine being trialled in Australia could revolutionise cancer treatment, saving patients time and money, doctors said. Doctors at Brisbane's Princess Alexandra (PA) Hospital are confident the new $2.5 million linear accelerator, now in use for intermediate or phase two trials on early stage breast cancer patients, would be of particular benefit to women from rural and remote areas. Dr Margot Lehman, a radiation oncologist conducting the trial, said women were being recruited at five centres in Australia, and two in New Zealand, under the Trans-Tasman Radiation Oncology Group (TROG). "If we can prove this is a feasible treatment option, then we will be going to a full-blown phase three trial where we will be comparing this technique with the standard six-week course for women with early stage breast cancer who have had breast conserving treatment," she said. PA Hospital's director of radiation oncology services Professor Bryan Burmeister said women in rural or remote areas often opted for a mastectomy rather than spending the time and money on travelling and accommodation needed for six weeks of treatment. "Now they only have to spend a week and that is a huge difference, in terms of cost, in terms of quality of life and numerous other things," he said. Older machines only targeted tumours in relation to the nearest bones, he said. But the new generation technology pinpointed tumours in soft tissue, enabling radiation treatment to be carried out on a smaller area and over [...]

p53 — Master and Commander

12/25/2007 Boston, MA William D. Foulkes, M.B., Ph.D. New England Journal of Medicine Volume 357:2539-2541 The gene known variously as p53, TP53, and Trp53 is currently featured in nearly 45,000 published articles listed in PubMed — a remarkable number suggesting that the protein product of this gene, p53, is one of the most important molecules in biology. When it was discovered in 1979, the p53 phosphoprotein (molecular mass, 53 kD) was postulated to have "a crucial role in the modulation of the transformed state."1 This idea has found support in innumerable studies, including the one reported on by Poeta et al. in this issue of the Journal (pages 2552–2561), in which somatic mutations in TP53 were associated with a poor outcome after surgical treatment of squamous-cell carcinoma of the head and neck. In particular, mutations that resulted in a shortened, and presumably malfunctioning, p53 protein or that interfered with the DNA-binding domain of p53 were independent predictors of a poor prognosis. So what is p53, and why is it important in cancer? The p53 protein functions primarily as a multitarget transcription factor. This means that it controls the expression of a wide range of genes with disparate functions. Additional cancer-related functions continue to be discovered, but thus far, its known functions include cell-cycle regulation, senescence, apoptosis, repair of DNA damage caused by genotoxic agents, angiogenesis, and regulation of oxidative stress.2 Such a broad range of relevant functions places p53 in a controlling position with respect to many cancer-related processes. With [...]

Researchers Train the Immune System to Deliver Virus that Destroys Cancer in Lab Models

12/25/2007 web-based article staff Biocompare (www.biocompare.com) An international team of researchers led by Mayo Clinic have designed a technique that uses the body’s own cells and a virus to destroy cancer cells that spread from primary tumors to other parts of the body through the lymphatic system. In addition, their study shows that this technology could be the basis for a new cancer vaccine to prevent cancer recurrence. The technology combines infection-fighting T-cells with the vesicular stomatitis virus that targets and destroys cancer cells while leaving normal cells unharmed. The study, which has not yet been replicated in humans, is significant because it describes a potential new therapy to treat and prevent the spread of cancer in patients. “We hope to translate these results into clinical trials. However, until those trials are done, it’s difficult to be certain that what we see in mouse models will clearly translate to humans. We’re hopeful that will be the case,” says Richard Vile, Ph.D., a Mayo Clinic specialist in molecular medicine and immunology and the study’s principal investigator. In primary cancers of the breast, colon, prostate, head and neck and skin, the growth of secondary tumors often pose the most threat to patients, not the primary tumor. The prognosis for these patients often depends upon the degree of lymph node involvement and whether the cancer has spread. Dr. Vile and colleagues theorized that they could control the spread of cancer through the lymphatic system (bone marrow, spleen, thymus and lymph nodes) by manipulating [...]

Smokebusters invite Young to give anti-smoking presentation

12/25/2007 Moberly, MO Janet Morales Moberly Monitor (/www.moberlymonitor.com) At age 14, Don Young's parents divorced. He was naturally upset and turned to friends to help fill the void. Many of these friends were smokers so to fit in and be part of the cool crowd he took up the bad habit too. He told his “Smoker's Story” and that of other smokers and tobacco chewers to the students at Westran High School with the aid of an electro-larynx since he no longer has a larynx (vocal chords) due to the cancer caused by years of smoking. “I didn't like it the first time,” said Young of his initial smoking experience. “It burned my tongue and throat. The doctor said that is a way the body tells you it doesn't belong. But I didn't listen to my body and my body got adjusted to it.” At age 48, Young thought his sore throat was the result of a cold. After it persisted, his wife Kay urged him to see a doctor. A nodule was found in his throat and removed. “Cigarettes were my best friend,” said Young. “I went everywhere with them. I smoked right up to the hospital to get my biopsy.” Young was assured the cancer was completely removed. Young had tried to quit smoking before but “that was enough to scare me”. He and his wife both threw away all their cigarettes, never to smoke again. But the doctor had been wrong. Three months after the first procedure, [...]

Cellphone Use Might Raise Mouth Cancer Risk

12/22/2007 United Kingdom staff Cellular- News (www.cellular-news.com) A new medical study is reporting that cell phone use raises the risk of mouth cancer. Five years of heavy use increased the chances of developing a tumor by around 50 percent compared with people who had never used a mobile phone. Previous studies into the links between phones and cancer have generated conflicting results with the vast majority claiming to have found no evidence of serious health risks, although some have found increases in cancer rates around the ear. The lifestyles of 402 people with benign mouth tumors and 56 with malignant tumors were compared to a control group of 1,266 people. Those who used mobile phones were more likely than normal to develop parotid gland tumors. The parotid is the largest of the salivary glands and sits at the back of the mouth not far from the ear. Long-term users of mobile phones tended to develop tumors on the same side of the head as the phone was normally held. People who used mobile phones in rural areas, where the phone has to work harder to make contact with the nearest base station, were found to be at greater risk. The cause of the heightened risk was not established. Most studies have looked at the way the electromagnetic fields created by phones warm tissue; however, the levels of the fields are thought too small to have a heating effect. Instead, some researchers believe the fields have the power to disrupt chemical [...]

HPV May Cause Second Cancers

12/22/2007 Augusta, GA staff www.wjbf.com About 15 years ago we learned that HPV, the human papilloma virus, causes cervical cancer. Now, researchers say, that could be just the beginning. They're looking into an HPV risk for other, or second cancers. Camille Ragin, Ph.D., M.P.H., Epidemiologist, "We realized that these cervical cancer patients, when we looked at these second cancers, they were primarily at an increased risk of developing head and neck cancers and also lung cancer." Women aren't the only ones at risk. Five years ago, Johns Hopkins researchers found HPV in oral cancer, and most of the patients were men. Maura Gillison, M.D., Head & Neck Oncologist, "To our surprise, it turned out HPV was in a significant number of these cancers, and they seemed to have distinct characteristics that made them different from cancers that were, that didn't have HPV in them." Most of the cancers started in the tonsils and were not associated with smoking or drinking. Dr. Gillison, "What was critical was just the number of oral sexual partners you've had in your lifetime." Findings from the studies could raise new questions about the HPV vaccine used to prevent cervical cancer. Dr. Gillison, "If the vaccine is shown to be effective in preventing oral HPV infection, then it would be indicated regardless of gender." Dr. Ragin, "That certainly cannot be ruled out because there are so many other cancers in men, anal cancers and other types of cancers, penile cancers that are in men, that are [...]

Scientists Weigh Stem Cells Role as Cancer Cause

12/22/2007 New York, NY Gina Kolata New York Times (nytimes.com) Within the next few months, researchers at three medical centers expect to start the first test in patients of one of the most promising — and contentious — ideas about the cause and treatment of cancer. The idea is to take aim at what some scientists say are cancerous stem cells — aberrant cells that maintain and propagate malignant tumors. Although many scientists have assumed that cancer cells are immortal —that they divide and grow indefinitely — most can only divide a certain number of times before dying. The stem-cell hypothesis says that cancers themselves may not die because they are fed by cancerous stem cells, a small and particularly dangerous kind of cell that can renew by dividing even as it spews out more cells that form the bulk of a tumor. Worse, stem cells may be impervious to most standard cancer therapies. Not everyone accepts the hypothesis of cancerous stem cells. Skeptics say proponents are so in love with the idea that they dismiss or ignore evidence against it. Dr. Scott E. Kern, for instance, a leading pancreatic cancer researcher at Johns Hopkins University, said the hypothesis was more akin to religion than to science. At stake in the debate is the direction of cancer research. If proponents of the stem-cell hypothesis are correct, it will usher in an era of hope for curing once-incurable cancers. If the critics are right, the stem-cell enthusiasts are heading down a [...]

Cancer Surgery Switch

12/22/2007 Torquay, England staff www.thisissouthdevon.co.uk Life saving surgery for people with cancer of the head and neck is to move from Torbay Hospital to Exeter, it has been revealed. Around 50 people a year are currently treated at Torbay Hospital for the disease, Torbay Council's Stronger Communities Scrutiny Board heard before giving the decision their blessing. Under the plans being brought in patients will still have initial consultancy and follow up appointments at the Shiphay site, but the actual operation will take place at the Royal Devon and Exeter Hospital. The scrutiny board heard there had been 'widespread professional debate' about the changes, along with future plans to have either Plymouth or Exeter as the one main centre for treatment. Guidelines say head and neck cancer centre services should be concentrated in centres serving one million people and at least 100 newly-diagnosed cases a year.

TP53 Mutations Associated with Decreased Survival in Head and Neck Cancer

12/21/2007 Memphis, TN staff CancerConsultants.com According to an article recently published in the New England Journal of Medicine, mutations in the TP53 gene result in lower survival rates for patients diagnosed with squamous-cell carcinoma of the head and neck. Patients with this genetic mutation may benefit from certain therapeutic approaches. Head and neck cancers originate in the oral cavity (lip, mouth, tongue), salivary glands, paranasal sinuses, nasal cavity, pharynx (upper back part of the throat), larynx (voice box), and lymph nodes in the upper part of the neck. Worldwide, head and neck cancer is diagnosed in approximately 640,000 people annually and is responsible for approximately 350,000 deaths each year. Squamous cell carcinoma of the head and neck is the most common type of head and neck cancer; it originates in squamous cells. As more is understood about cancer, genetics has been recognized as a crucial factor in the disease’s development. One area of genetic research involves the p53 protein, which is produced by the TP53 gene. The p53 protein suppresses the abnormal growth of cancer cells. If mutations exist in the TP53 gene, abnormal p53 proteins are produced that often lack the ability to suppress the growth of tumors. Researchers from the United States and Italy recently conducted a clinical trial to evaluate the potential effects of a mutated TP53 gene on outcomes among patients with squamous-cell carcinoma of the head and neck. This trial included 560 patients who underwent surgery in an attempt to cure their disease. Mutations of [...]
