- Advances In Lung Cancer Treatment
Scientists at the Ireland Cancer Center of University Hospitals Case Medical Center have developed methods for treating lung cancer cells that have become resistant to new anti-cancer agents. Led by Balazs Halmos, MD, hematologist/oncologist with the Ireland Cancer Center, the research team followed up on their prior study, reported in the New England Journal (NEJM), which observed that lung cancer cells can become resistant to novel targeted agents, such as Tarceva (erlotinib), a medicine in widespread use for non-small-cell lung cancer (NSCLC). Tarceva is among a new generation of cancer therapies that disrupt the molecular target responsible for stimulating tumor growth. The drug targets the receptor for the epidermal growth factor protein (EGFR) to halt the spread of cancer cells. Clinical applications of the new drug initially yielded good results with approximately 10 percent of patients experiencing complete remission of their disease........ - Secondhand smoke proves to be serious
A study published in this months issue of the Journal of Periodontology found that subjects with periodontitis who were exposed to secondhand smoke were more likely to develop bone loss, the number one cause of tooth loss. Researchers studied rats that were induced with periodontal disease. One group was not exposed to cigarette smoke while the other two groups were exposed to either 30 days of smoke inhalation produced by non-light cigarettes (cigarettes containing higher tar, nicotine and carbon monoxide levels) or light cigarettes (cigarettes containing lower tar, nicotine and carbon monoxide levels). Results showed that bone loss was greater in the subjects exposed to secondhand smoke regardless of if it was smoke from light or non-light cigarettes than those who were exposed to no smoke at all........ - Race affects tobacco absorption in children
New research suggests that a child's race may be a factor in determining his/her susceptibility to tobacco toxins linked to environmental tobacco smoke (ETS). The study, reported in the recent issue of CHEST, the peer-evaluated journal of the American College of Chest Physicians (ACCP), reveals that African American children with asthma, who are exposed to ETS, have significantly higher toxin levels when in comparison to their Caucasian counterparts........ - New Cigarettes Designs Don't Offer Lower Cancer Risks
The tobacco company's description of its new cigarette brand seems to promise a lot. "May present less risk of cancer linked to smoking," the company boasts on its Web site, making it a natural choice "for smokers who have decided not to quit, but who are interested in a cigarette that responds to concerns about certain smoking-related illnesses, including cancer." Another tobacco firm, in a print ad for the brand, has crowed "All of the taste. Less of the toxins"........ - Lack Of A Protein In Lung Tumors
A study of human lung tumors indicates that patients with lung cancer who lack a particular protein may do more poorly than those with normal levels of that same protein. If the findings are verified in a clinical trial, the absence of the protein might be used to identify patients with lung cancer who need more aggressive treatment after surgery........ - Smoking Greatly Increases The Risk For Lung Cancer
Lung cancer is the most deadly of all cancers. It is the leading cause of cancer death for both men and women, as per the American Cancer society (ACS). More people die of this than of colon, breast, and prostate cancers combined. The ACS predicts that in 2007 there will be about 213,380 new cases. Of this number, about 160,390 people will die........ - Easy To Avoid Mesothelioma
It is known that mesothelioma is caused by breathing asbestos fibers into the lungs. When this happens, the lungs or the abdomen may be affected by the disease. Because asbestos is so strongly linked to mesothelioma, regulations have been created to set limits on the amount of exposure to asbestos a worker can have in a workplace........ - Cause of Smokers' Cravings
Video of Jed Rose explaining the regions of the brain that control craving is available in the following formats: RealMedia, QuickTime and Windows Media Video. DURHAM, N.C. -- Within the mind of every smoker trying to quit rages a battle between the higher-order functions of the brain wanting to break the habit and the lower-order functions screaming for another cigarette, say researchers at Duke University Medical Center. More often than not, that cigarette gets lit........ - Lung Cancer-derived EGFR Mutants
A new study sheds light on how some small-molecule tyrosine kinase inhibitors, including two that are currently being used clinically to treat cancer, interact with wild-type and mutated forms of the epidermal growth factor receptor (EGFR). The research, reported in the recent issue of the journal Cancer Cell, published by Cell Press, may help to guide rational use of currently available EGFR inhibitors and provides new direction for the design and development of even more potent inhibitors that are tailored to specific EGFR mutants........ - Green Tea May Fight Lung Cancer
Looks like a cup of green tea is a good fight to lung cancer according to this article published on the medicinenet.com site: Green tea may fight lung cancer and could inspire the creation of new lung cancer drugs, researchers report. But it may be too soon to count on a cup of green tea to curb lung cancer. So far, the researchers have only tested green tea extract against human lung cancer cells in test tubes, not people........ - CT Scans Still Not Advised for Lung Cancer Screening
Using CT scan to screen for lung cancer provides no benefit to smokers: The use of computed tomography (CT) scans to screen current or former smokers for lung cancer is still too experimental to recommend for widespread medical use, as per results from a new study. The potential use of imaging tests like CT to screen for lung cancer has been the subject of lively debate in recent years. Some prior studies have suggested that such tests can find lung cancer earlier, when tumors are smaller and more likely operable. The question is whether this translates into helping people live longer and whether it has an adverse affect on their quality of life........ - If Mom Smoked During Pregnancy
Quitting smoking may be more difficult for individuals whose mothers smoked during pregnancy, as per animal research conducted by Duke University Medical Center researchers. Prenatal exposure to nicotine is known to alter areas of the brain critical to learning, memory and reward. Researchers at the Duke Center for Nicotine and Smoking Cessation Research have discovered that these alterations may program the brain for relapse to nicotine addiction. Rodents exposed to nicotine before birth self administer more of the drug after periods of abstinence than those that had not been exposed........ - Dual Gene Therapy Suppresses Lung Cancer
Combination gene treatment delivered in lipid-based nanoparticles drastically reduces the number and size of human non-small cell lung cancer tumors in mice, scientists at The University of Texas M. D. Anderson Cancer Center and the University of Texas Southwestern Medical Center report in the Jan. 15 edition of Cancer Research........ - How Body Fights To Control Spread Of Cancer
Scientists at the University of Liverpool have found how two molecules fight in the blood to control the spread of cancer cells. Researchers discovered that a large protein, which forms a protective shield around cancer cells and prevents them from causing secondary tumours, is attacked by a small protein that exists in the blood........ - New Lung Cancer Therapy With Fewer Radiation Treatments
You probably have not to take that prolonged therapy with radiation treatment. Now there is a new cancer therapy that cuts down the amount of radiation a patient must endure. This new therapy method would cut 35 therapys of radiation to five therapys. This new technique is called sterotactic body radiotherapy........
