(HealthDay)—Monica Barlow, a 35-year-old from Maryland, was training for a half-marathon when she noticed she couldn't shake a bad cough and ongoing fatigue. After a couple of rounds of antibiotics from an urgent care clinic didn't work, she sought another opinion. http://medicalxpress.com/news/2013-04-clinical-trials-woman-cancer.html Cancer Thu, 18 Apr 2013 13:19:19 EST news285509952 A new minimally invasive tumor ablation technique is providing hope for liver cancer patients who can't undergo surgery or thermal ablation, a study shows. http://medicalxpress.com/news/2013-04-ablation-technique-liver-cancer-patients.html Cancer Thu, 18 Apr 2013 00:00:04 EST news285436299 (HealthDay News) —For advanced colon cancer patients who have developed liver tumors, so-called "radioactive beads" implanted near these tumors may extend survival nearly a year longer than among patients on chemotherapy alone, a small new study finds. http://medicalxpress.com/news/2013-01-microbeads-boost-survival-advanced-colon.html Cancer Mon, 21 Jan 2013 12:39:40 EST news277994369 Using two successive pairs of specialized CT scans, a team of Johns Hopkins and Dutch radiologists has produced real-time images of liver tumors dying from direct injection of anticancer drugs into the tumors and their surrounding blood vessels. Within a minute, the images showed whether the targeted chemotherapy did or did not choke off the tumors' blood supply and saved patients a month of worry about whether the treatment, known as chemoembolization, was working or not, and whether repeat or more powerful treatments were needed. http://medicalxpress.com/news/2013-01-paired-ct-scans-chemo-killing-liver.html Cancer Tue, 01 Jan 2013 07:46:34 EST news276248547 Liver cancer is the sixth most common cancer worldwide and the third leading cause of cancer-associated deaths. Yet even for such a frequent and deadly disease, the pathogenesis of this cancer remains obscure. Now, a team of scientists in Japan has shown that genes involved in regulating how tightly DNA is wound into chromosomes are commonly mutated in liver tumors. The finding points to potential new and much-needed therapeutic strategies. http://medicalxpress.com/news/2012-11-identification-mutations-common-liver-cancers.html Cancer Fri, 16 Nov 2012 07:14:42 EST news272272473 Investigators at Nationwide Children's Hospital have identified a mouse model that could help evaluate the risk that viral vectors used in gene therapy might promote tumor formation as a side-effect. The study appears in Molecular Therapy.  http://medicalxpress.com/news/2012-10-mouse-viral-vectors-tumors.html Cancer Fri, 26 Oct 2012 09:00:01 EST news270459764 Researchers headed by Erwin Wagner, the Director of the BBVA Foundation-CNIO Cancer Cell Biology Programme at the Spanish National Cancer Research Centre (CNIO), have deciphered how a stress-inducible gene regulator, AP-1, controls the survival of liver tumor-initiating cells. These results, published in the online edition of Nature Cell Biology, could provide new preventive strategies and identify potentially targetable molecules to prevent liver cancer. http://medicalxpress.com/news/2012-10-oncogenic-network-specific-liver-cancer.html Cancer Sun, 07 Oct 2012 14:01:41 EST news268837278 Hepatocellular carcinoma (HCC) is the third leading cause of cancer deaths worldwide and is associated with exposure to hepatitis B virus (HBV). Patients carrying the virus have a 100-fold greater risk of developing HCC, but exactly why was unclear until now. Wing Kin Sung at the A*STAR Genome Institute of Singapore and the National University of Singapore, John Luk at the A*STAR Institute of Molecular and Cell Biology and the National University of Singapore and co-workers have now identified genetic mechanisms by which a virus contributes to this common form of cancer. http://medicalxpress.com/news/2012-08-molecular-mechanisms-virus-contributes-cancer.html Cancer Wed, 29 Aug 2012 08:50:05 EST news265447292 One way to tackle a tumor is to take aim at the metabolic reactions that fuel their growth. But a report in the February Cell Metabolism shows that one metabolism-targeted cancer therapy will not fit all. That means that metabolic profiling will be essential for defining each cancer and choosing the best treatment accordingly, the researchers say. http://medicalxpress.com/news/2012-02-metabolic-profiles-essential-personalizing-cancer.html Cancer Tue, 07 Feb 2012 13:10:01 EST news247841927 Cancer cells are well known for their altered metabolisms, which may help them generate the energy they need for rapid growth. Using an emerging imaging technology, researchers reporting in the July Cell Metabolism, a Cell Press publication, have discovered that those metabolic shifts actually develop even before detectable tumors form. By the same token, the studies in mice with liver cancer show that the altered tumor metabolism shifts back before established tumors shrink. http://medicalxpress.com/news/2011-07-metabolic-shift-early-cancer-clue.html Cancer Tue, 05 Jul 2011 12:31:25 EST news229087865
