Nearly 800,000 Deaths Prevented Due to Declines in Smoking

Source: National Cancer Institute Twentieth-century tobacco control programs and policies were responsible for preventing more than 795,000 lung cancer deaths in the United States from 1975 through 2000, according to an analysis funded by the National Cancer Institute (NCI), part of the National Institutes of Health. If all cigarette smoking in this country had ceased following the release of the first Surgeon General’s report on smoking and health in 1964, a total of 2.5 million people would have been spared from death due to lung cancer in the 36 years following that report, according to the analysis.  The results of this study were published online March 14, 2012, in the Journal of the National Cancer Institute. “These findings provide a compelling illustration of the devastating impact of tobacco use in our nation and the enormous benefits of reducing rates of smoking,” said Robert Croyle, Ph.D., director of the Division of Cancer Control and Population Sciences at NCI.  “Although great strides have been made, we cannot relax our efforts.  The prevention and cessation of tobacco use continue to be vital priorities for the medical, scientific, and public health communities.” The researchers, part of the NCI-sponsored Cancer Intervention and Surveillance Modeling Network (CISNET), utilized a comparative modeling approach in which they constructed detailed cigarette smoking histories for individuals born from 1890 through 1970, and then related the histories to lung cancer mortality in mathematical models.  Using these models, the researchers were able to estimate the impact of changes in smoking patterns resulting [...]

Cancer Patients Who Smoke Report Worse Pain, Symptoms

Source: MedScapeToday.com February 24, 2012 (Palm Springs, California) — Cancer patients who smoke experience more severe symptoms than nonsmoking cancer patients and are also at greater risk of misusing opioids, a new study shows. "Our findings show a profile of higher levels of physical symptoms (pain, fatigue, poor appetite, and insomnia) and psychological symptoms (depression and anxiety) among smokers than non-smokers," report Diane Novy, PhD, from the Pain Management Center at the University of Texas MD Anderson Cancer Center in Houston, Texas, and colleagues. The findings underscore the importance of smoking cessation for this patient population, she told Medscape Medical News, even though it's unclear if there is a causal effect. "We don't know the cause. They may smoke more because of the pain," she said in an interview. However, studies also show that smoking has been known to increase certain types of pain such as back pain, and nerve pain, she added. "If we can motivate them to stop smoking, I think they're better off." The findings were presented here at the American Academy of Pain Medicine (AAPM) 28th Annual Meeting. Pain, Fatigue, Insomnia The study included 486 cancer patients (52% female), with a mean age of 55 years, who were referred to the Pain Management Center for uncontrolled pain. Ninety-four patients were smokers, and the rest (n = 356), classified as nonsmokers, were former smokers or never-smokers. The patients were diagnosed with a wide range of cancers, the most common being gastrointestinal (18.5%), followed by hematologic (15%) and [...]

Which Cancers Are Increasing Among Older Adults?

Source: AARP Cancers of the mouth and throat related to oral sex, as well as thyroid, liver and skin cancers are on the rise among older adults, according to  new stats released last week from the American Cancer Society. There was some good news, however. The death rate is down for the well-known major cancers. The society’s Cancer Statistics 2012 report found that overall, cancer deaths dropped by nearly two percent for both men and women  from 2004 to 2008. That may sound paltry, but Len Lichtenfeld, M.D., the society’s deputy chief medical officer, says it is more significant than it seems: Many people avoided even hearing the words “you have cancer” because advances in cancer treatment caught problems early, while still in the pre-cancerous stage, he said. The report found that death rates were down for all four major cancers — lung, colorectal, breast and prostate. The biggest drop was for lung cancer, which is down almost 40 percent in the number of men dying from the disease, thanks to fewer Americans smoking. Deaths among women from breast cancer declined 34 percent, mainly because of increases in mammogram screening and a decrease in hormone use for menopause, the ACS report said. On the other hand, some cancers are increasing, particularly among older Americans. According to Medscape News , the ACS found that people 55 to 64 years of age had the highest increase in incidence rates for liver and HPV-related oral cancers; people 65 and older also had an increase in incidence rates [...]

New Study Indicates Tobacco Industry Was Aware of Their Own Products Dangers

Source: USA Today Tobacco companies knew for decades that cigarette smoke was radioactive and potentially carcinogenic but kept that information from the public, according to a new study. The tobacco industry began investigations into the possible effects of these radioactive particles, identified as polonium-210, on smokers as early as the 1960s, says the study by UCLA researchers who analyzed dozens of previously unexamined industry documents. "I've not seen a document before that's specifically cited the industry's own internal research finding that sufficient levels of polonium-210 can cause cancer," says Matt Myers of the Campaign for Tobacco-Free Kids. He says the study reinforces the need for the U.S. Food and Drug Administration to scrutinize tobacco products. This week, the FDA began requiring tobacco companies to disclose detailed information about new products and changes to existing ones. The study, published in the peer-reviewed journal Nicotine & Tobacco Research, suggests the FDA make removal of the radioative particles from tobacco products a top priority. "We used to think that only the chemicals in the cigarettes were causing lung cancer," said Hrayr S. Karagueuzian, lead author of the study. Now, Karagueuzian said, the industry's own research shows that polonium-210, absorbed by tobacco leaves and inhaled by smokers, is dangerous. He said UCLA researchers found that the radioactivity could cause 120 to 138 deaths for every 1,000 regular smokers over a 25-year period. Karagueuzian said tobacco companies have declined techniques that could help eliminate polonium-210 from tobacco because of concern that smokers might lose the "instant [...]

New Study for Cancer Patients to Help Improve the Body’s Ability to Fight Illness

Source: Sign On San Diego A Santa Monica research center will test an experimental therapeutic filtering device being developed by Aethlon Medical on blood taken from cancer patients, the San Diego company said Wednesday. The study will target exosomes, bubbles of protein and RNA molecules excreted by cancerous cells that can block immune system cells from fighting the illness. By removing exosomes from circulating blood, Aethlon officials hope their device will improve the body's ability to fight cancer and the effectiveness of treatments such as chemotherapy. Blood taken from 25 patients with non-small cell lung cancer, prostate cancer, melanoma, sarcoma, and head and neck cancer will be circulated through the Hemopurifier device. In clinical use, blood would be filltered directly from the patient and returned to the body in a similar way to kidney dialysis. However, in the newly announced pre-clinical trial blood will not be returned to patients, Aethlon Chairman and Chief Executive Officer James Joyce said. "If we validate that our Hemopurifier is efficient in capturing exosomes, its possible that we could transition towards a human treatment study to evaluate exosome clearance from the entire circulatory system," he said. The test will be conducted by the Sarcoma Oncology Center, a nonprofit independent research institute focused on cancer therapy development. "This clinical histological study is a critical validation step in Aethlon's Hemopurifier strategy for cancer," said Dr. Sant Chawla, the trial's chief investigator. "The concept of 'subtractive therapy', eliminating a major mechanism of tumor progression and resistance to drugs, [...]

Oral, Head and Neck Cancers Continue to Increase While Most U.S. Cancer Death Rates are on the Decline

Source: SHOTS (NPR's Health Blog) The rate at which Americans die from cancer continues to fall, according to the latest estimates from the American Cancer Society. As a result, nearly 900,000 cancer deaths were avoided between 1990 and 2007, the group figures. Survival gains have come as mortality rates have declined for some of the most common malignancies, including colorectal cancer, breast cancer in women and prostate cancer. Still, the ACS estimates there will nearly 1.6 million new cancers diagnosed this year, and about 572,000 deaths from the disease. The incidence of cancers hasn't budged much for men in recent years, after falling quite a bit during the first half of the last decade. Cancer incidence for women has been falling since 1998. The report was just published online by CA: A Cancer Journal for Clinicians. Lung cancer remains the biggest killer for both men and women. All told, about 160,000 people in the U.S. are expected to die from it this year. Starting in 1987, more women have died from lung cancer each year than breast cancer. One section of the report focuses on a persistent and, in some cases, widening gap in cancer death rates between people with the least education and those with the most. Educational attainment is often used in research as a proxy for socioeconomic status. American Cancer Society epidemiologist Elizabeth Ward, one of the report's authors, tells Shots, "People of a lower socioeconomic status are more likely to smoke and less likely to get [...]

Cancer death rate gap widens based on education

Source: apnews.myway.com Author: Mike Stobbe The gap in cancer death rates between college graduates and those who only went to high school is widening, the American Cancer Society reported Friday. Among men, the least educated died of cancer at rates more than 2 1/2 times that of men with college degrees, the latest data show. In the early 1990s, they died at two times the rate of most-educated men. For women, the numbers aren't as complete but suggest a widening gap also. The data, from 2007, compared people between the ages of 25 and 64. People with college degrees are seeing a significant drop in cancer death rates, while people who have spent less time in school are seeing more modest improvements or sometimes none at all, explained Elizabeth Ward, who oversees research done by the cancer society. The cancer society estimates there will be nearly 1.6 million new cancer cases in the United States this year, and 571,950 deaths. It also notes that overall cancer death rates have been dropping since the early 1990s, but the decline has been greater for some groups more than others. Experts believe that the differences have to do with education, how much people earn and where they live, among other factors. Researchers like to use education as a measuring stick because death certificates include that information. "Just because we're measuring education doesn't mean we think education is the direct reason" for the differences among population groups, Ward said. That said, the cancer death [...]

High risk of developing ONJ for cancer patients on bisphosphonates

Source: Dr.Bicuspid.com Research has shown that cancer patients on bisphosphonates are at risk of developing osteonecrosis of the jaw (ONJ) and that those on the intravenous form of the drug are at a higher risk compared with those on the oral drugs. However, a new study that looked at cancer patients on zoledronic acid (ZOL) and chemotherapy combined with the antiangiogenic agent bevacizumab (BEV) who underwent a dental exam before starting treatment found that none of them developed ONJ (JADA, May 2011, Vol. 142:5, pp. 506-513). Researchers from the University of Siena in Italy investigated the incidence of and risk factors for ONJ in patients with metastases to the bone from solid tumors who received ZOL and BEV. Their study included 59 patients (34 with breast cancer and 25 with non-small cell lung cancer [NSCL]) who received 4 mg of ZOL intravenously every four weeks and 15 mg per kg of BEV every three weeks. The median time the participants received ZOL therapy was 18 months, while the median time participants received BEV therapy was 16 months. The researchers took several measures to reduce the study participants' risk of developing ONJ, including the following: Dental caries and periodontal disease were treated before starting study treatment. Mouth rinses with chlorhexidine and local antibiotic agents were administered before baseline oral hygiene. Recommendations were made for maintaining good oral hygiene. Teeth were extracted at least four weeks before starting ZOL and BEV therapy. Invasive dental procedures were avoided during treatment. If invasive dental [...]

New Smokeless Tobacco from Sweden is Gaining Popularity in the US

Source: DrugFree.org A type of smokeless tobacco popular in Sweden called snus is growing in popularity in the United States. While most recognize that it is a safer alternative to cigarettes or older forms of smokeless tobacco, others are concerned that it will attract young people, becoming a steppingstone to cigarettes, says a researcher who spoke this week at the Smokeless Tobacco Summit in Austin, TX. There is also concern that smokers may use snus in places where they can’t smoke, which will encourage them to keep smoking instead of quitting, says Lois Biener, PhD, Adjunct Professor, Department of Psychology at the University Of Massachusetts – Boston and Senior Research Fellow at the Center for Survey Research, University Of Massachusetts – Boston. Snus (pronounced snoos) was first introduced in several U.S. test markets in 2006, and has been available nationwide since 2009. It is sold under several brands including Marlboro Snus and Camel Snus. The product is different from other types of smokeless tobacco in several important ways, Dr. Biener says. Snus is manufactured using a process that makes it lower in carcinogens called tobacco-specific nitrosamines. Snus also doesn’t stimulate saliva the way that snuff does and thus doesn’t require spitting. A person using snus puts a small pouch filled with the product between the lip and the gum. Dr. Biener’s research has shown that the primary group of snus users in the United States is male smokers. “There is very little trial of the product among females and virtually [...]

New Breath Test to Identify Head and Neck Cancer

Source: British Journal of Cancer M Hakim, S Billan, U Tisch, G Peng, I Dvrokind, O Marom, R Abdah-Bortnyak, A Kuten and H Haick Abstract Background: Head-and-neck cancer (HNC) is the eighth most common malignancy worldwide. It is often diagnosed late due to a lack of screening methods and overall cure is achieved in <50% of patients. Head-and-neck cancer sufferers often develop a second primary tumour that can affect the entire aero-digestive tract, mostly HNC or lung cancer (LC), making lifelong follow-up necessary. Methods: Alveolar breath was collected from 87 volunteers (HNC and LC patients and healthy controls) in a cross-sectional clinical trial. The discriminative power of a tailor-made Nanoscale Artificial Nose (NA-NOSE) based on an array of five gold nanoparticle sensors was tested, using 62 breath samples. The NA-NOSE signals were analysed to detect statistically significant differences between the sub-populations using (i) principal component analysis with ANOVA and Student's t-test and (ii) support vector machines and cross-validation. The identification of NA-NOSE patterns was supported by comparative analysis of the chemical composition of the breath through gas chromatography in conjunction with mass spectrometry (GC–MS), using 40 breath samples. Results: The NA-NOSE could clearly distinguish between (i) HNC patients and healthy controls, (ii) LC patients and healthy controls, and (iii) HNC and LC patients. The GC–MS analysis showed statistically significant differences in the chemical composition of the breath of the three groups. Conclusion: The presented results could lead to the development of a cost-effective, fast, and reliable method for the differential [...]
