Palifermin reduces severe mucositis in head and neck cancer

Source: http://www.medscape.com/ Author: Janis C. Kelly Palifermin (Kepivance), which is currently approved for preventing mucositis associated with total-body irradiation and stem-cell transplantation in hematologic malignancies, also prevents oral mucositis in patients with head and neck cancer undergoing radiation and chemotherapy, according to 2 randomized trials published online June 13 in the Journal of Clinical Oncology. Michael Henke, MD, who led both studies, told Medscape Medical News that "this shows for the first time that radiation-induced mucositis can be ameliorated — and this in a phase 2/3 design!" Dr. Henke is from the Department of Radiation Oncology at University Clinic in Freiburg, Germany. The multicenter studies included researchers from Austria, France, Germany, Hungary, Italy, Poland, Spain, the United Kingdom, and the United States. The first study was a double-blind randomized placebo-controlled trial of 186 patients with stage II to IVB carcinoma of the oral cavity, oropharynx, hypopharynx, or larynx. Treatment included radiation, 60 or 66 Gy, after complete or incomplete resection, delivered at 2 Gy per fraction and 5 fractions per week. Treatment also included cisplatin 100 mg/m2 on days 1 and 22 (and on day 43 with incomplete resection). Patients were randomized to weekly palifermin 120 μg/kg or placebo from 3 days before and throughout radiochemotherapy. The primary end point was the incidence of severe oral mucositis (World Health Organization [WHO] grades 3 to 4). Palifermin reduced oral mucositis incidence to 51% (41 of 92), compared with 67% (63 of 94) with placebo (P = .027), shortened median mucositis from [...]

New labels may not go far enough

Source: www.denverpost.com Author: Rhonda Hackett How far would you go to stop a killer? Smoking continues to kill more Americans every year than alcohol, AIDS, car accidents, illegal drugs, murders and suicides combined. Tobacco use remains the leading preventable cause of death and the single greatest driver of health-care costs in Colorado. Despite concerted efforts over recent years to educate people about the dangers of tobacco use, 46.6 million American adults smoke, while kids alone are responsible for roughly $2 billion in annual cigarette sales revenues. More than 400,000 people die every year from tobacco use (4,300 in Colorado), while an additional 50,000 adults die as a result of second-hand smoke exposure. More than 8 million Americans currently suffer from tobacco- caused illnesses, resulting in an estimated $96 billion in public and private health care expenditures each year. In Colorado, the tab is about $1.3 billion per year. Simply put, tobacco is the single most lethal and costly legal commodity available in America today. The U.S. Food and Drug Administration has now followed the lead of other developed nations by requiring cigarette packages carry graphic warning labels. FDA Commissioner Margaret Hamburg said at a White House briefing, "We want kids to understand smoking is gross - not cool - and there's really nothing pretty about having mouth cancer." Critics of the warning labels cite the fact that smoking is a legal activity and as such products associated with it should not be subject to government mandate discouraging use. The Institute [...]

Late diagnoses may have caused U.K. oral cancer deaths

Source: http://www.drbicuspid.com/ Author: DrBicuspid Staff Late diagnoses and referrals could have resulted in the deaths of several oral cancer patients at a dental hospital in Belfast, U.K., according to a story in the Belfast Telegraph. A report found the Belfast Health Trust guilty of "serious deficiencies" after 15 oral cancer patients at the Royal Dental Hospital received late diagnoses and referrals. Health Minister Edwin Poots said that four of the 15 could have died as a consequence. Poots also disclosed that five senior directors of the trust received pay increases of between 5% and 10%, which cannot now be legally retrieved, involving a total of 26,000 pounds ($41,793 U.S). Also, government officials were told there may be "potentially material shortcomings" over the procurement of a security services contract at the Belvoir Park Hospital site in south Belfast. The problems were attributed to excessive workloads, exacerbated by the lack of an adequate secretarial and administrative support system. In February, it was revealed that two years ago the trust launched a major review of 3,000 clinical records belonging to dentistry patients in Northern Ireland.

Hypersensitivity Reactions to Erbitux Caused by Tick Bites.

Source: Gastroenterology & Endoscopy News Hypersensitivity reactions to cetuximab (Erbitux, ImClone Systems/Bristol-Myers Squibb), a monoclonal antibody approved for use in colorectal cancer, are not caused by the drug itself but by preexisting immunoglobulin E (IgE) antibodies that may result from tick bites, researchers have found. Cetuximab, like other monoclonal antibodies, is generally associated with a low rate of severe anaphylactic reactions (3%), but reports of such reactions to cetuximab have recently increased in southeastern states, including Tennessee and North Carolina. Researchers found IgE antibodies in pretreatment samples of 68% of patients allergic to cetuximab that were specific for galactose-α-1,3-galactose, an oligosaccharide present on the Fab portion of the cetuximab heavy chain. The authors noted that rates of anaphylactic reaction may be lower with other monoclonal antibodies because cetuximab is produced in the mouse cell line SP2/0, which expresses this oligosaccharide, whereas most other monoclonal antibodies are produced in a Chinese hamster ovary cell line that does not express this molecule. Theories to explain the increased hypersensitivity of patients in the Southeast initially centered on exposure to worms, such as roundworms or tapeworms. However, researchers now believe the true culprit may be ticks, whose bites have resulted in the development of this type of IgE antibody. Pretreatment samples were obtained from 76 people treated with cetuximab at centers mainly in Tennessee, Arkansas and North Carolina; the control group included 72 people in Tennessee, 49 patients with cancer in northern California and 341 women in Boston. Of the patients on cetuximab, 25 [...]
