According to a recent study, there is a new mechanism of drug release using 3D superhydrophobic materials that utilizes air as a removable barrier to control the rate at which drug is released. http://phys.org/news246894426.html Chemistry Fri, 27 Jan 2012 13:47:20 EST news246894426 The metabolism of lung cancer patients is different than the metabolism of healthy people. And so the molecules that make up cancer patients' exhaled breath are different too. A new device pioneered at the University of Colorado Cancer Center and Nobel-Prize-winning Technion University in Haifa, Israel uses gold nanoparticles to trap and define these molecules in exhaled breath. By comparing these molecular signatures to control groups, the device can tell not only if a lung is cancerous, but if the cancer is small-cell or non-small-cell, and adenocarcinoma or squamous cell carcinoma. http://phys.org/news240747256.html Nanotechnology Thu, 17 Nov 2011 10:14:31 EST news240747256 When lung cancer strikes, it often spreads silently into more advanced stages before being detected. In a new article published in Nature Nanotechnology, biological engineers and medical scientists at the University of Missouri reveal how their discovery could provide a much earlier warning signal. http://phys.org/news235316694.html Nanotechnology Thu, 15 Sep 2011 14:47:12 EST news235316694 Healthcare workers can most directly affect quality of life (QOL) of patients with advanced stage lung cancer by helping manage symptoms such as pain, lack of energy, shortness of breath, coughing, difficulty sleeping and dry mouth, according to a study recently published in the journal Oncology Nursing Forum. http://phys.org/news214758341.html Medicine & Health Thu, 20 Jan 2011 15:05:58 EST news214758341 A study in the New England Journal of Medicine shows more than half of patients with a specific kind of lung cancer are responding positively to a treatment that targets the gene that drives their cancer. http://phys.org/news207500581.html Medicine & Health Thu, 28 Oct 2010 16:30:01 EST news207500581 A novel approach detects genetically abnormal cells in the blood of non-small cell lung cancer patients that match abnormalities found in tumor cells and increase in number with the severity of the disease, a research team led by scientists at The University of Texas MD Anderson Cancer Center report in the journal Clinical Cancer Research. http://phys.org/news199027732.html Medicine & Health Thu, 22 Jul 2010 15:10:03 EST news199027732 In clinical trials for cancer, it is standard for clinicians rather than patients to report adverse symptom side effects from treatments, such as nausea and fatigue. At present, patient self-reporting, although important, is not a well studied source of this information. A new longitudinal study from researchers at Memorial Sloan-Kettering Cancer Center finds that while clinicians' and patients' reporting of treatment side effects are very different from each other, together they provide a more complete, clinically meaningful picture of the treatment experience. http://phys.org/news177702169.html Medicine & Health Tue, 17 Nov 2009 18:50:03 EST news177702169 Non-small cell lung cancer patients who have progressed on a cetuximab-containing regimen may respond to erlotinib, Fox Chase Cancer Center researchers reported today at the annual meeting of the International Association for the Study of Lung Cancer. http://phys.org/news168412827.html Medicine & Health Sun, 02 Aug 2009 06:50:01 EST news168412827 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 (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 Countless people have heard the phrase, "You have lung cancer," but only 50 can say they've completed a new treatment at Temple University that doubles their chances of surviving the deadly disease — and without the conventional radiation regimen or surgery. Doctors in the Radiation Oncology Department say the technique, stereotactic body radiotherapy, or SBRT, not only improves a person's odds of surviving early stage lung cancer, but may reduce the need for future surgeries. http://phys.org/news155403104.html Medicine & Health Wed, 04 Mar 2009 15:33:39 EST news155403104 Gefitinib, also known as Iressa, the once-promising targeted therapy for the treatment of non-small cell lung cancer, has proven as effective as chemotherapy as a second-line therapy for the disease with far fewer side effects, according to an international Phase III clinical trial, led by researchers at The University of Texas M. D. Anderson Cancer Center. http://phys.org/news146472603.html Medicine & Health Fri, 21 Nov 2008 06:50:03 EST news146472603
