(PhysOrg.com) -- University of Cincinnati (UC) cancer cell biologists have identified a distinct gene linked to increased lung cancer susceptibility and development. They say this gene—known as RGS17—could result in a genetic predisposition to develop lung cancer for people with a strong family history of the disease. http://phys.org/news159022902.html Medicine & Health Wed, 15 Apr 2009 14:02:13 EST news159022902 Black patients suffering from lung cancer are less likely to receive recommended chemotherapy and surgery than white lung cancer patients, a disparity that shows no signs of lessening. That is the conclusion of a new study published in the May 15, 2009 issue of CANCER, a peer-reviewed journal of the American Cancer Society. The study's findings indicate that efforts are needed to provide appropriate treatments for black patients and to educate them about the value of those treatments. http://phys.org/news158835141.html Medicine & Health Mon, 13 Apr 2009 09:52:50 EST news158835141 Higher doses of radiation combined with chemotherapy improve survival in patients with stage III lung cancer, according to a new study by researchers at the University of Michigan Comprehensive Cancer Center. http://phys.org/news158409811.html Medicine & Health Wed, 08 Apr 2009 11:44:02 EST news158409811 Multiple, anatomically distinct lung cancer tumors may frequently arise from a single cancer cell, according to a retrospective analysis of patient tumor samples published in the April 7 online issue of the Journal of the National Cancer Institute. http://phys.org/news158345481.html Medicine & Health Tue, 07 Apr 2009 17:52:07 EST news158345481 An inflammatory factor already linked to several diseases, including pulmonary disease, lung cancer, and arthritis, may also be responsible for the insulin resistance that comes with obesity, according to a new study published in the April issue of Cell Metabolism, a Cell Press publication. http://phys.org/news158327353.html Medicine & Health Tue, 07 Apr 2009 12:50:24 EST news158327353 An experimental vaccine that triggers the patient's immune system to identify and attack specific tumor cells is showing new promise for the treatment of early lung cancer. Thoracic surgeons at Rush University Medical Center are researching the vaccine called MAGE-A3 Antigen-Specific Cancer Immunotherapeutic, which is designed to kill cancer cells without harming normal cells. Rush is one of only five hospitals in Illinois offering the vaccine. http://phys.org/news158244764.html Medicine & Health Mon, 06 Apr 2009 13:53:20 EST news158244764 A new study by Ohio State University cancer researchers shows that boosting the level of a molecule called miR-29b in acute myeloid leukemia (AML) cells can reverse gene changes that trap the cells in an immature, fast growing state of development. http://phys.org/news157974933.html Medicine & Health Fri, 03 Apr 2009 10:56:24 EST news157974933 Seventeen people are still dying from lung cancer each week in Northern Ireland despite a small improvement in survival rates for the disease. http://phys.org/news157954027.html Medicine & Health Fri, 03 Apr 2009 05:07:30 EST news157954027 Three South Korean manufacturers said Thursday they are recalling baby powder products after health authorities announced that they contain cancer-causing asbestos. http://phys.org/news157871921.html Medicine & Health Thu, 02 Apr 2009 06:19:00 EST news157871921 The US Supreme Court on Tuesday dismissed cigarette giant Philip Morris's appeal of a multi-million dollar punitive damage verdict awarded to the widow of a longtime smoker who died of lung cancer. http://phys.org/news157744064.html Medicine & Health Tue, 31 Mar 2009 18:48:15 EST news157744064 Relying on principles similar to those that cause Jell-O to congeal into that familiar, wiggly treat, University of Michigan researchers are devising a new method of detecting nitric oxide in exhaled breath. http://phys.org/news157018879.html Chemistry Mon, 23 Mar 2009 09:22:48 EST news157018879 In the past few years, a number of anti-cancer drugs have been developed which are directed selectively against specific key molecules of tumor cells. Among these is an antibody called cetuximab, which attaches to a protein molecule that is found in large amounts on the surface of many types of cancer cells. When this surface molecule, called epidermal growth factor receptor, or EGF-R for short, is blocked by cetuximab, the cancer cell receives less signals stimulating cell division. http://phys.org/news156521387.html Medicine & Health Tue, 17 Mar 2009 15:10:20 EST news156521387 (PhysOrg.com) -- A future sensor may take away a patient's breath while simultaneously determining whether the patient has breast cancer, lung cancer, diabetes or asthma. A University of Missouri researcher is developing a device that will analyze breath or urine samples for volatile markers inside the body that indicate disease. These volatile markers, such as alkanes, acetones or nitric oxide, give doctors clues about what is happening inside the body and can be used as a diagnostic tool. http://phys.org/news155938204.html Chemistry Tue, 10 Mar 2009 21:10:27 EST news155938204 A new study shows for the first time that a microRNA-based diagnostic test can objectively identify squamous lung cancer with 96% sensitivity, according to Harvey Pass, M.D. of the NYU Cancer Institute at NYU Langone Medical Center, one of the authors of the study published on-line ahead of print in the Journal of Clinical Oncology. http://phys.org/news155892724.html Medicine & Health Tue, 10 Mar 2009 08:33:05 EST news155892724 (PhysOrg.com) -- The combined expression of three specific genes in lung cancer tumors may predict both cancer growth and a poorer prognosis, according to a study led by researchers in the Duke Institute for Genome Sciences & Policy and the Duke Comprehensive Cancer Center. http://phys.org/news155844873.html Medicine & Health Mon, 09 Mar 2009 19:15:21 EST news155844873 A new analysis has found that certain variations in genes that repair DNA can affect a person's risk of developing Hodgkin disease.

These findings, which appear in the on-line early edition of journal Proceedings of the National Academy of Sciences, may lead to a new, relatively non-invasive biomarker for smoking-related lung diseases. http://phys.org/news151076573.html Biology Tue, 13 Jan 2009 13:42:53 EST news151076573 About 1100 people each year die in the UK from lung cancer related to indoor radon, but current government protection policies focus mainly on the small number of homes with high radon levels and neglect the 95% of radon related deaths caused by lower levels of radon, according to a study published on bmj.com today. http://phys.org/news150541340.html Medicine & Health Wed, 07 Jan 2009 09:02:20 EST news150541340 Cancer and cell biology experts at the University of Cincinnati (UC) have identified a new tumor suppressor that may help scientists develop more targeted drug therapies to combat lung cancer. http://phys.org/news150389078.html Medicine & Health Mon, 05 Jan 2009 14:44:38 EST news150389078 A research team from the University of California, San Diego School of Medicine has identified a protein produced by cancerous lung epithelial cells that enhances metastasis by stimulating the activity of inflammatory cells. Their findings, to be published in the January 1 issue of the journal Nature, explain how advanced cancer cells usurp components of the host innate immune system to generate an inflammatory microenvironment hospitable for the metastatic spread of lung cancer. The discovery could lead to a therapy to limit metastasis of this most common lethal form of cancer. http://phys.org/news149951977.html Medicine & Health Wed, 31 Dec 2008 13:19:37 EST news149951977 While examining patterns of DNA modification in lung cancer, a team of international researchers has discovered what they say is a surprising new mechanism.
