Snus spat erupts in Norway

Source: Ice News A row has erupted over snuff tobacco in Norway after a state researcher said the government should be promoting it as a way of stopping smoking. Health officials have dismissed the criticisms of Karl Erik Lund, however, saying the substance, known as snus in Norway, is highly addictive and can cause cancer. Mr Lund, of the state institute for alcohol and drug research SIRUS, told Aftenposten newspaper that Norway should start being honest with its people by telling them that snus is “much less dangerous” than smoking. Dr Maja-Lisa Løchen, a professor of preventive medicine at the Univerity of Tromsø, however, told the newspaper that she was “furious” that they had given the story “so much space”. “No research has documented that using snus is an effective way to stop smoking,” Dr Løchen told Aftenposten. “On the contrary, some smokers can wind up using both forms of tobacco.” Løchen added that users, who usually place the snus under their lips to absorb the nicotine, also risk contracting other forms of cancer. She added that the health ministry would not be recommending the product. Snus is banned in many European countries but has a long tradition of use in Norway and Sweden where it is still legal.

Red Meat Consumption Linked to Increased Risk of Total, Cardiovascular, and Cancer Mortality

Source: Harvard School of Public Health Boston, MA -- A new study from Harvard School of Public Health (HSPH) researchers has found that red meat consumption is associated with an increased risk of total, cardiovascular, and cancer mortality. The results also showed that substituting other healthy protein sources, such as fish, poultry, nuts, and legumes, was associated with a lower risk of mortality. The study will be published online in Archives of Internal Medicine on March 12, 2012. “Our study adds more evidence to the health risks of eating high amounts of red meat, which has been associated with type 2 diabetes, coronary heart disease, stroke, and certain cancers in other studies,” said lead author An Pan, research fellow in the Department of Nutrition at HSPH. The researchers, including senior author Frank Hu, professor of nutrition and epidemiology at HSPH, and colleagues, prospectively observed 37,698 men from the Health Professionals Follow-up Study for up to 22 years and 83,644 women in the Nurses’ Health Study for up to 28 years who were free of cardiovascular disease (CVD) and cancer at baseline. Diets were assessed through questionnaires every four years. A combined 23,926 deaths were documented in the two studies, of which 5,910 were from CVD and 9,464 from cancer. Regular consumption of red meat, particularly processed red meat, was associated with increased mortality risk. One daily serving of unprocessed red meat (about the size of a deck of cards) was associated with a 13% increased risk of mortality, and one daily [...]

Cancer Patients’ Health Benefits From Physical Activity

Source: MedicalNewsToday.com According to an investigation published on bmj.com, cancer patients who have completed their primary cancer-related treatment, who engage in physical activity, can enhance their health. Earlier studies discovered that individuals with cancer anticipate to return to normal daily activities after completing their primary cancer-related treatment. However, these patients often find they experience lower physical activity, increased fatigue and a decrease in quality of life (QOL). Although, several health factors including QOL can be enhanced through engaging in exercise, according to studies. Investigators from the University of Hong Kong examined the results of 34 human trials that evaluated how exercise effects adult individuals with cancer. Each trial consisted of an average of 93 participants who had either suffered from prostate, breast, lung, colorectal, gynecologic or gastric cancer. The average age of the participants was 55 years. The trials included resistance, strength and aerobic training for a median duration of 13 weeks. Health improvements, such as BMI and body weight, blood sugar control, lower limb strength, fatigue, depression and QOL, were observed among participant's who received breast cancer treatment who engaged in a period of physical activity. Improvements, such as oxygen consumption, depression, BMI, body weight, handgrip strength and QOL, were also observed among patients who completed treatments for other types of cancer. Furthermore, variations in intensity and type of physical activity influenced the physical health of cancer patients and played a vital role in the effects of the exercise. Individuals with breast cancer found that resistance and aerobic exercise [...]

Oral Sex Cancer Virus More Common in Men Than Women, Study Finds

Source: Bloomberg.com About 10 percent of men and 3.6 percent of women are orally infected with human papillomavirus, which is acquired through oral sex and can cause cancer. There are two peaks in the age people are infected -- 30 to 34 and 60 to 64, according to the study published today in the Journal of the American Medical Association. The virus is linked to throat cancer, and is becoming a more common cause of the disease as Americans quit smoking. The virus, called HPV, is the most-common sexually transmitted virus in the U.S., where half the population will be infected at some time in their lives, according to the Centers for Disease Control and Prevention. It is known to cause cervical, vulvar, vaginal, penile and anal cancer. The higher HPV infection rate in men explains why their head and neck cancer rates are greater, said Maura Gillison, a professor at the Ohio State University College of Medicine in Columbus. “This provides pretty strong evidence that the higher infection rate is the reason why,” said Gillison, the study’s lead author, in a telephone interview. “This is a jumping board for additional research.” Besides sex, other demographics associated with oral HPV infection include age, lifetime number of sex partners, and the number of cigarettes smoked each day. The research is the first population-based study to examine how many men and women were infected, Gillison said. Existing Vaccines Though Merck & Co.’s Gardasil and GlaxoSmithKline Plc (GSK)’s Cervarix target genital HPV, it’s [...]

Lab-made tissue picks up the slack of Petri dishes in cancer research

New research demonstrates that previous models used to examine cancer may not be complex enough to accurately mimic the true cancer environment. Using oral cancer cells in a three-dimensional model of lab-made tissue that mimics the lining of the oral cavity, the researchers found that the tissue surrounding cancer cells can epigenetically mediate, or temporarily trigger, the expression or suppression of a cell adhesion protein associated with the progression of cancer. These new findings support the notion that drugs that are currently being tested to treat many cancers need to be screened using more complex tissue-like systems, rather than by using conventional petri dish cultures that do not fully manifest features of many cancers. "Research on cancer progression has been drawn largely using models that grow cancer cells in plastic dishes. Our research reveals a major shortcoming in the experimental systems used to study cancer development. When using simplified culture systems in which cells are grown on plastic, cancer cells grow as a two dimensional monolayer and lack the three-dimensional tissue structure seen in human cancer. As a result, complex interactions that occur between the cancer cells and the surrounding tissue layers are not accounted for," said first author Teresa DesRochers, PhD, a graduate of the Sackler School of Graduate Biomedical Sciences at Tufts, currently in the department of biomedical engineering at Tufts University School of Engineering. The researchers report that the three-dimensional network of cell interactions activates epigenetic mechanisms that control whether genes critical for cancer development will be [...]

Tongue and tonsil cancer patients surviving longer

Source: Dr.Biscuspid.com The five-year survival rate for U.S. patients with cancer of the base of the tongue or tonsils doubled between 1980 and 2002, according to a new study in Cancer Causes & Control (January 2012, Vol. 23:1, pp. 153-164). In addition, patients with human papillomavirus (HPV)-related cancers had greater survival rates than those with other oral cancers, and survival was greater for male patients than females regardless of age, according to the study authors, from the New York Eye and Ear Infirmary, the University of Utah School of Medicine, and the University of California, Los Angeles School of Public Health. However, patients with subsequent multiple cancers showed no overall survival improvement. The incidence rates of tongue and tonsil cancers have increased significantly in recent decades in the U.S., particularly among younger patients, the researchers noted. At the same time, a number of studies have shown a strong association between HPV infection and tongue and tonsil cancers. For this study, they used data from the Surveillance, Epidemiology, and End Results (SEER) 1973-2006 registry system to examine changes in survival rates among patients with base of tongue, tonsil, and other tongue cancers in recent decades. The study included 10,704 patients with squamous tongue or tonsil cancer who were at least 20 years old. The researchers separated the patients into those with one primary cancer and those with subsequent multiple cancers, then compared trends using three nonoverlapped periods: 1980-1982, 1990-1992, and 2000-2002. The first group included those with only one primary base of tongue, [...]

Distant Metastases in Head-and-Neck Squamous Cell Carcinoma Treated with Intensity-modulated Radiotherapy

Source: International Journal of Radiation Oncology, Biology and Physics (IJROBP Online) December 2011 PURPOSE: To determine the pattern and risk factors for distant metastases in head-and-neck squamous cell carcinoma (HNSCC) after curative treatment with intensity-modulated radiotherapy (IMRT). METHODS AND MATERIALS: This was a retrospective study of 284 HNSCC patients treated in a single institution with IMRT. Sites included were oropharynx (125), oral cavity (70), larynx (55), hypopharynx (17), and unknown primary (17). American Joint Committee on Cancer stage distribution includes I (3), II (19), III (42), and IV (203). There were 224 males and 60 females with a median age of 57. One hundred eighty-six patients were treated with definitive IMRT and 98 postoperative IMRT. One hundred forty-nine patients also received concurrent cisplatin-based chemotherapy. RESULTS: The median follow-up for all patients was 22.8 months (range, 0.07-77.3 months) and 29.5 months (4.23-77.3 months) for living patients. The 3-year local recurrence-free survival, regional recurrence-free survival, locoregional recurrence-free survival, distant metastasis-free survival, and overall survival were 94.6%, 96.4%, 92.5%, 84.1%, and 68.95%, respectively. There were 45 patients with distant metastasis. In multivariate analysis, distant metastasis was strongly associated with N stage (p = 0.046), T stage (p<0.0001), and pretreatment maximum standardized uptake value of the lymph node (p = 0.006), but not associated with age, gender, disease sites, pretreatment standardized uptake value of the primary tumor, or locoregional control. The freedom from distant metastasis at 3 years was 98.1% for no factors, 88.6% for one factor, 68.3% for two factors, and 41.7% for three factors (p <0.0001 by log-rank [...]

Anti-cancer vaccines are emerging

Source: Boston Globe Author: Karen Weintraub Long envisioned drugs to harness the immune system could reshape treatments For more than a century, doctors and patients have dreamed of using the body’s own defenses to fight cancer. Why, they wondered, can’t the immune system - so good at tracking down and destroying intruders - attack the tumor cells that invade healthy tissue? Finally, science is catching up with this vision. Just reaching the market in a big way, so-called therapeutic vaccines turn a patient’s immune system against the cancer and help prevent a recurrence. If the early promise of these vaccines is realized, they will soon join the basic arsenal for fighting all cancers, several researchers said. “We really are in a transformative moment,’’ said Dr. Glenn Dranoff, professor of medicine at Harvard Medical School and a medical oncologist and immunologist at the Dana-Farber Cancer Institute. Prostate cancer patients were the first to benefit. A therapeutic vaccine called Provenge received federal approval last year after studies showed it safely extended the lives of advanced prostate cancer patients for an average of 4.1 months. Then came a vaccine called Yervoy, designed to attack melanoma, a particularly dangerous form of skin cancer. Cancer generally turns down the body’s immune response to a tumor; Yervoy is designed to turn it back on, enhancing the immune system’s ability to kill cancer cells. Many more cancer vaccines are under development, with hundreds of trials underway in patients with breast, prostate, lung, kidney, colon, cervical, brain, and [...]

‘Sicker’ Canadians struggle to obtain treatment: report

Source: CTV.ca TORONTO — Canadians with chronic conditions are frequent users of the health-care system, but a new report shows many experience considerable difficulty getting the medical treatment they need. So-called sicker Canadians -- most of whom are age 50 or older -- have one or more of seven chronic conditions: high blood pressure, heart disease, cancer, diabetes, joint pain or arthritis, chronic lung problems such as asthma or chronic obstructive pulmonary disease (COPD), and mental health problems such as depression or anxiety. Those who are chronically ill are among the highest users of health services: they are more likely to be hospitalized, have surgery, visit emergency departments and take prescription medications. But cost can be a major barrier to accessing that care, says the Health Council of Canada, citing results from the 2011 Commonwealth Fund International Health Policy Survey, which included almost 4,000 Canadians. Almost a quarter of respondents who rated their health as fair or poor reported skipping a dose of medication or not filling a prescription due to the cost, compared with just 10 per cent of other Canadians, the survey found. The council said that one-in-four ratio is significant because 90 per cent of sicker Canadians take at least one prescription drug, while 54 per cent take four or more medications. As well, about one in eight said they have skipped a recommended test or followup treatment due to cost concerns, compared to just five per cent of those without chronic health problems. "The experiences of [...]
