UNMC Doctor Working to Reduce Suicide Among Cancer Patients

5/25/2008 Omaha, NE Jenny Nowatzke KPTM Fox42 News (www.kptm.com) Patients with head or neck cancer only make up 2% of all cancer cases. But, a staggering 20% of those patients end up committing suicide. Now, a local doctor is determined to reduce that number all the way down to zero. "You just feel helpless and selfless and after awhile, you give up hope," said John Allbery. Five years ago, Allbery was faced with the fight of his life - throat cancer. He wasn't a smoker, so when he heard the doctor's words, he was speechless. "Naturally, I didn't believe it," he said. After undergoing radiation and chemotherapy, Dr. Bill Lydiatt with the Nebraska Medical Center asked Allbery to help him with a new clinical trial. Its goal - to reduce the risk of depression and suicide in head and neck cancer patients. "We tried to look at ways to intervene to make this a better outcome for them," Lydiatt said. He gave half the patients a placebo, and the other an antidepressant. After 12 weeks, he says the results were amazing. "The group that had the placebo had a fifty percent of depression, compared to fifteen percent in the treatment group," Lydiatt said. Allbery says, lucky for him, he was in the right group. "Thinking back now, now that I know I got the drug, I can't even imagine what it would have been like if I hadn't." With the success of the first trial, Lydiatt received a $1.6 million [...]

Nanotechnology makes radiation therapy of cancer more effective

5/25/2008 web-based article staff Foresight Nanotech Institute (www.foresight.org) A nanotech approach to overcoming the resistance of some cancer cells to radiation therapy has been successfully tested in mice. From the National Cancer Institute’s Alliance for Nanotechnology in Cancer “Nanoparticle-Induced heating boosts antitumor radiation therapy“: Radiation therapy is a time-honored and effective component of modern cancer therapy, but its ultimate utility is limited by the fact that some cancer cells are resistant to ionizing radiation. Now, a research team led by Sunil Krishnan, M.D., of the University of Texas M.D. Anderson Cancer Center, has found that pretreating tumors with gold nanoparticles and near-infrared radiation dramatically improves the response of tumors to radiation therapy. Reporting its work in the journal Nano Letters [abstract], the Texas investigators showed that inducing a mild temperature rise in tumors increases blood flow throughout tumors, particularly in those regions of a tumor that are normally deprived of oxygen that results from the disrupted network of blood vessels found deep within tumors. To produce the mild temperature rise, or hyperthermia, the researchers used gold nanoparticles and infrared light. Gold nanoparticles become warm, or even hot, when irradiated with near-infrared light, an effect that other researchers are exploring as an anticancer therapy. In this study, the researchers chose to induce mild hyperthermia, which by itself will not kill tumor cells, using low-intensity infrared radiation. Although other studies had demonstrated convincingly that mild hyperthermia sensitizes tumors to radiation therapy, previous methods of raising the temperature of tumors have not proved [...]

One Man’s Advice From Four Cancer Battles

5/24/2008 New York City, NY Tara Parker-Pope New York Times (nytimes.com) Hamilton Jordan, the former White House chief of staff for President Jimmy Carter, was a well-known force in the health community. During the past 24 years he battled four different forms of cancer and urged cancer patients to empower themselves with information. After bouts with non-Hodgkins lymphoma, prostate cancer and skin cancer, Mr. Jordan, 63, yesterday died as a result of mesothelioma, another form of cancer. Mr. Jordan often speculated that his lymphoma may have resulted from exposure to the chemical Agent Orange while serving as a volunteer during the Vietnam War. Mesothelioma also has been linked to the chemical. In his 2001 memoir, “No Such Thing as a Bad Day,'’ Mr. Jordan outlined his “Top 10 Tips for Cancer Patients.'’ He spoke about them during this undated interview with WebMD. Here they are: No. 1: Be an active partner in the medical decisions that are made about your life. Don’t be passive. Learn about your disease, and participate in the decisions that are made….For example with my lymphoma, if I would have accepted the first treatment offered, I’d be dead today. It was assumed that I only had a mass in my chest. I later learned that the lymphoma was all through my body. No. 2: Seek and know the truth about your illness, and prognosis. If you don’t have the facts, and don’t know the truth, you won’t make good decisions. It takes courage to ask questions [...]

Loss of Teeth and Periodontal Disease May Be Associated with Increased Risk of Cancer

5/23/2008 Ketchum, ID staff CancerConsultants.com Three recent publications have suggested an association between periodontal disease and/or tooth loss and an increased risk of developing cancer. There are many factors associated with an increased or decreased risk of developing various types of cancer. Until recently there had been few studies looking at the association between periodontal disease and/or tooth loss and the risk of developing various types of cancer. However, periodontal disease and/or tooth loss has been the subject of several recent studies; three of these studies are summarized here. Japanese researchers have reported that there is a significant association between tooth loss and risk of cancers of the head and neck, esophagus, and lung. The details of this study were published in the May 1, 2008 issue of Cancer Epidemiology, Biomarkers & Prevention.1 They looked at 5,240 patients with cancer and 10,480 control patients without cancer. They categorized patients into four groups based on the number of remaining teeth. They found that a decreased number of remaining teeth was associated with a 68% increased risk of head and neck cancer and a more than double increase in the risk of esophageal and lung cancer. Researchers from the Imperial College London and Harvard School of Public Health have reported that periodontal disease was associated with an increase in overall cancer risk in never smokers.2 This study looked at 48,375 male health professionals with a follow-up of over 17 years. There were 5,720 persons with cancer, excluding non-melanoma skin cancer and non-aggressive [...]

HPV, periodontitis work to increase tongue-cancer risk

5/23/2008 Buffalo, NY Lois Baker Univ. of Buffalo Reporter (www.buffalo.edu/reporter) Persons with periodontitis who also are infected with human papillomavirus (HPV) are at increased risk of developing tongue cancer, new research conducted at the School of Dental Medicine has shown. Periodontitis is a chronic inflammatory disease that destroys connective tissue and bone supporting the teeth. It has been associated with various systemic diseases, including diabetes and heart disease. Researchers from UB and Roswell Park Cancer Institute published the first study showing an association between long-standing periodontitis and risk of tongue cancer in the May 2007 issue of Archives of Otolaryngology—Head and Neck Surgery. Studies conducted elsewhere have found that HPV is an independent risk factor for a subset of head and neck cancers. The UB researchers now have shown that the two infections appear to work in tandem to boost the chances of developing tongue cancer. Mine Tezal, assistant professor in the Department of Oral Diagnostic Sciences, UB dental school, and research scientist at Roswell Park Cancer Institute, presented results of this research recently at the 2008 American Association of Dental research meeting. “Evidence of periodontitis-HPV synergy has important practical implications,” said Tezal, “because there is a safe treatment for periodontitis, but no treatment for HPV infection. If these results are confirmed by other studies, this has a tremendous relevance in predicting and intervening in the initiation and prognosis of HPV-related diseases, including head and neck cancers.” The study involved 30 patients newly diagnosed with squamous cell carcinoma on the [...]

NYU Students Receive OCF Award for Excellence in Public Service

NYU Dental Students Show They Have a Lot to Teach About Giving Back The Oral Cancer Foundation recently honored the two student co-chairs of Oral Cancer Walk 2008, an awareness-building and fund-raising event coordinated by the New York University Dental School’s chapter of SNDA (Student National Dental Association).  The two honorees are fourth-year student Marcus Johnson and third-year student Dmitry Baron. Marcus and Dmitry both worked on the 2006 and 2007 events and, despite extremely busy schedules, enthusiastically embraced the challenge of running this year’s event. Oral Cancer Walk 2008 took place the morning of Saturday, April 19 in Harlem’s Marcus Garvey Park, drew over 900 walkers, and raised over $30,000 to support the cause of the early detection of oral cancer. Funds raised through the event sponsor the work of The Oral Cancer Foundation. The event also featured free oral cancer, blood pressure, and cholesterol screenings in conjunction with the Harlem Hospital, speeches from oral cancer survivors, and musical entertainment both before and after the walk. Dr. Jocelyn Jeffries, the chair of Oral Cancer Walk 2007, attended the event and lent her moral support to the new event leadership. “For Marcus and Dmitry to find the time to coordinate such a significant event while tending to their dental school studies represents a tremendous sacrifice,” said Brian Hill, Founder and Executive Director of the Oral Cancer Foundation, which again was both one of the event’s sponsors, and benefactors.  “Their exceptional leadership, passion and altruism have generated not only badly-needed funding, [...]

More links found between cancer in men and HPV, but men aren’t approved for vaccination

5/22/2008 Chicago, IL Brian Boyer Medill Reports (news.medill.northwestern.edu) Men are neither vaccinated nor screened for human papillomavirus, but two university studies suggested last week that it may be the cause of cancer for many men, and that those cancers could have been prevented. The virus, better known as HPV, is the primary cause of cervical cancer in women. Recent research, at the University of Michigan and University of Louisville, suggests that it is also the cause of a disease that disproportionately affects men, cancers of the head and neck. "You should be testing everybody," said Payal Desai, leader of a pilot study at the Louisville's James Graham Brown Cancer Center. Both men and women carry HPV, the virus that will affect at least 50 percent of sexually active people, according to the Food and Drug Administration, though only a fraction of those will develop cancer. More than 35,000 new cases of head and neck cancer are expected to be diagnosed in the United States in 2008, according to the American Cancer Society. Twice as many men as women will develop the disease, which the society estimates will kill 7,590 Americans this year. Currently a screening test only exists for women. Similarly, a vaccine for HPV exists, but is only approved for use in women ages 9 to 26. Studies are under way to test the efficacy of the HPV vaccine in men, according to the FDA. If the vaccine were successful in preventing HPV infections in men, the studies suggest [...]

Head And Neck Cancer Patients Less Depressed With Citalopram

5/22/2008 Omaha, NE Peter M Crosta MedicalNewsToday.com According to a study published in the May issue of Archives of Otolaryngology-Head & Neck Surgery, patients may be able to prevent depression during therapy if they begin a regimen of the antidepressant citalopram prior to beginning head and neck cancer (HNC) treatment. Providing background information, the authors note that, "Treatment for head and neck cancer can be arduous and debilitating." They add that, "Psychiatric morbidity in these patients is frequent and underdiagnosed. Major depressive disorder has been reported in up to 40 percent of patients with head and neck cancer, typically within the first three months of diagnosis." To determine the link between treatment with the antidepressant citalopram hydrobromide and major depressive disorder in patients undergoing therapy for HNC, William M. Lydiatt, M.D. (University of Nebraska Medical Center and Nebraska Methodist Hospital, Omaha) and colleagues conducted a randomized clinical trial. During randomization, 15 participants were placed in a group that received 40 milligrams per day of the antidepressant citalopram and 13 were assigned to take placebo. During the 12 weeks that the patients took these medications, they underwent HNC treatment; every four weeks, the patients received a depression screening. After 12 weeks, 22 patients were assessed. Four weeks after stopping the medication, 23 patients finished a final study visit. The researchers found that, "The numbers of subjects who met predefined cutoff criteria for depression during the 12 weeks of active study were five of 10 (50 percent) taking placebo and two of [...]

Avocados can prevent cancers

5/22/2008 Soweto, South Africa Zinhle Mapumulo Sowetan (www.sowetan.co.za) The virtues of eating avocado pears have long been encouraged, but new research has shown that this super food could actually help prevent oral and prostate cancer. A study conducted at Ohio State University in the United States has found that the phytochemicals in the fruit are able to kill certain types of cancer cells and may even prevent some precancerous cells from developing. Dietician Jane Badham said the study was one of the first-ever research linking avocados with oral cancer, and the possible prevention of it. “Scientists found that phytochemicals extracted from avocados target multiple signalling pathways and increase the amount of reactive oxygen within the cells, leading to cell death in pre-cancerous cell lines. The phytochemicals did not, however, harm normal cells,” Badham said. She said more research was still necessary. This is an average of 1400 new cases of oral cancer every year, according to the South African National Cancer Registry. But experts agree that the incidence is probably much higher. Three-quarters of oral cancer patients are males. The Ohio study follows research done in 2005 at the University of California, Los Angeles, (UCLA), where scientists noted that avocados may inhibit prostate cancer. Badham said: “What was most exciting about the UCLA research is how carotenoids, vitamins and other phytochemicals in avocados may have a synergistic effect against prostate cancer.”
