(AP) -- They're not cures, but two novel drugs produced unprecedented gains in survival in separate studies of people with melanoma, the deadliest form of skin cancer, doctors reported Sunday. http://phys.org/news226549097.html Medicine & Health - Cancer Mon, 06 Jun 2011 03:18:41 EST news226549097 Two big studies suggest possible new ways to screen healthy people for cervical or prostate cancers, but a third disappointed those hoping for a way to detect early signs of deadly ovarian tumors. http://phys.org/news224961785.html Medicine & Health - Cancer Wed, 18 May 2011 18:23:31 EST news224961785 In stark contrast to normal cells, which only divide a finite number of times before they enter into a permanent state of growth arrest or simply die, cancer cells never cease to proliferate. Now, scientists at the Salk Institute for Biological Studies have uncovered an important clue to one of the mechanisms underlying cancer cell immortality. http://phys.org/news222609023.html Medicine & Health - Cancer Thu, 21 Apr 2011 12:50:40 EST news222609023 Two new studies highlight the power of sequencing cancer patients' genomes as a diagnostic tool, helping doctors decide the best course of treatment and researchers identify new cancer susceptibility mutations that can be passed from parent to child. http://phys.org/news222451688.html Medicine & Health - Cancer Tue, 19 Apr 2011 17:08:22 EST news222451688 (PhysOrg.com) -- Research published last week in the journal PNAS may have identified a promising new target for developing drugs against one of the most common types of lung cancer. http://phys.org/news222425004.html Medicine & Health - Cancer Tue, 19 Apr 2011 09:43:38 EST news222425004 Squamous cell cancers, which can occur in multiple organs in the body, can originate from hair follicle stem cells, a finding that could result in new strategies to treat and potentially prevent the disease, according to a study by researchers with UCLA's Jonsson Comprehensive Cancer Center and the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA. http://phys.org/news222424620.html Medicine & Health - Cancer Tue, 19 Apr 2011 09:37:23 EST news222424620 A new study shows how inflammation can help cause cancer. Chronic inflammation due to infection or to conditions such as chronic inflammatory bowel disease is associated with up to 25 percent of all cancers. http://phys.org/news222424253.html Medicine & Health - Cancer Tue, 19 Apr 2011 09:32:33 EST news222424253 High-grade serous ovarian cancer (HGSOC), the fifth-deadliest cancer among American women, is thought by many scientists to often be a fallopian tube malignancy masquerading as an ovarian one. While most of the evidence linking HGSOC to the fallopian tubes has so far been only circumstantial, a new Dana-Farber Cancer Institute study suggests there is a direct connection, a finding that could aid in the development of better treatments for the cancer. http://phys.org/news222361125.html Medicine & Health - Cancer Mon, 18 Apr 2011 15:58:56 EST news222361125 For many types of cancer, the original tumor itself is usually not deadly. Instead, it's the spread of a tiny subpopulation of cells from the primary tumor to other parts of the body -- the process known as metastasis—that all too often kills the patient. Now, researchers at Albert Einstein College of Medicine of Yeshiva University have identified two molecules that enable cancer to spread inside the body. These findings could eventually lead to therapies that prevent metastasis by inactivating the molecules. http://phys.org/news221408606.html Medicine & Health - Cancer Thu, 07 Apr 2011 15:23:45 EST news221408606 A newly discovered hybrid gene appears to play a direct role in some stomach cancers, according to an international team of scientists led by researchers at Duke-NUS Graduate Medical School Singapore. http://phys.org/news221318805.html Medicine & Health - Cancer Wed, 06 Apr 2011 14:27:06 EST news221318805 Scientists from the School of Pharmacy at Queen's University Belfast and Almac Discovery Ltd have developed a new treatment for cancer which rather than attacking tumours directly, prevents the growth of new blood vessels in tumours, starving them of oxygen and nutrients, thereby preventing their growth. http://phys.org/news221195053.html Medicine & Health - Cancer Tue, 05 Apr 2011 04:04:44 EST news221195053 Researchers at the University of California, San Diego School of Medicine say a "stress response" mechanism used by normal cells to cope with harsh or demanding conditions is exploited by cancer cells, which transmit the same stress signal to surrounding cells, triggering an inflammatory response in them that can aid tumor growth. http://phys.org/news221153087.html Medicine & Health - Cancer Mon, 04 Apr 2011 18:40:01 EST news221153087 A team of researchers at the University of California, San Francisco has discovered a new way to predict breast cancer survival based on an "immune profile" – the relative levels of three types of immune cells within a tumor. Knowing a patient's profile may one day help guide treatment. http://phys.org/news221027129.html Medicine & Health - Cancer Sun, 03 Apr 2011 05:25:45 EST news221027129 In the single largest cancer genomics investigation reported to date, scientists have sequenced the whole genomes of tumors from 50 breast cancer patients and compared them to the matched DNA of the same patients' healthy cells. This comparison allowed researchers to find mutations that only occurred in the cancer cells. http://phys.org/news220985675.html Medicine & Health - Cancer Sat, 02 Apr 2011 17:55:02 EST news220985675 (PhysOrg.com) -- With currently available early-detection methods for breast cancer, many people can be treated successfully. But for the 20 percent of patients with so-called triple-negative breast cancer, the outcome is bleak. Now, however, researchers from Harvard Medical School (HMS) and Baylor College of Medicine have identified a critical molecular component to the disease, one that suggests potential therapies involving combinations of FDA-approved, readily available drugs. http://phys.org/news220885052.html Medicine & Health - Cancer Fri, 01 Apr 2011 14:30:01 EST news220885052 Researchers have described how the most common gene mutation found in acute myeloid leukaemia starts the process of cancer development and how it can cooperate with a well-defined group of other mutations to cause full-blown leukaemia. http://phys.org/news220449667.html Medicine & Health - Cancer Sun, 27 Mar 2011 13:02:02 EST news220449667 (PhysOrg.com) -- New drugs that specifically target the mutated genes responsible for cancer growth have shown great success in extending the lives of patients, with far fewer side effects than conventional anti-cancer therapies. Unfortunately, many patients become resistant to these drugs due to secondary mutations. http://phys.org/news220257675.html Medicine & Health - Cancer Fri, 25 Mar 2011 07:42:45 EST news220257675 Research led by Daitoku Sakamuro, PhD, Assistant Professor of Pathology at LSU Health Sciences Center New Orleans and the LSUHSC Stanley S. Scott Cancer Center, has identified a protein that enables the activation of a DNA-repair enzyme that protects cancer cells from catastrophic damage caused by chemo and radiation therapy. This protein, called c-MYC oncoprotein, can initiate and promote almost all human cancers and discovering the role it plays in cancer treatment resistance may lead to advances that save lives. The work is published in the March 29, 2011 issue of Science Signaling. Although scientists have known that cancer cells can acquire resistance to DNA-damaging therapeutic agents, the genetic mechanisms through which this occurs have remained unclear until now. http://phys.org/news220195950.html Medicine & Health - Cancer Thu, 24 Mar 2011 14:32:40 EST news220195950 Researchers at the University of Pennsylvania's Abramson Cancer Center have discovered a novel way of treating pancreatic cancer by activating the immune system to destroy the cancer's scaffolding. The strategy was tested in a small cohort of patients with advanced pancreatic cancer, several of whose tumors shrank substantially. The team believes their findings – and the novel way in which they uncovered them -- could lead to quicker, less expensive cancer drug development. http://phys.org/news220195281.html Medicine & Health - Cancer Thu, 24 Mar 2011 14:21:40 EST news220195281 (PhysOrg.com) -- Avian embryos could join the list of model organisms used to study a specific type of cell migration called epiboly, thanks to the results of a study published this month in the journal Developmental Dynamics. The new study provides insights into the mechanisms of epiboly, a developmental process involving mass movement of cells as a sheet, which is linked with medical conditions that include wound healing and cancer. http://phys.org/news220114730.html Medicine & Health - Cancer Wed, 23 Mar 2011 16:01:22 EST news220114730 A breakthrough discovery by the University of East Anglia (UEA) and Children's Hospital Boston promises an effective new treatment for one of the deadliest forms of cancer. http://phys.org/news220107848.html Medicine & Health - Cancer Wed, 23 Mar 2011 14:04:49 EST news220107848 The latest clues suggesting potential new ways to treat melanoma come from an unlikely source: fish. http://phys.org/news220107800.html Medicine & Health - Cancer Wed, 23 Mar 2011 14:03:35 EST news220107800 (PhysOrg.com) -- The discovery that a certain protein is over-expressed in patients with oral cancer may give new treatment hope to people suffering from the particularly aggressive, localized forms of head and neck cancer. http://phys.org/news219563638.html Medicine & Health - Cancer Thu, 17 Mar 2011 06:54:09 EST news219563638 Dana-Farber Cancer Institute scientists report they have shrunk or slowed the growth of notoriously resistant pancreatic tumors in mice, using a drug routinely prescribed for malaria and rheumatoid arthritis. http://phys.org/news219417595.html Medicine & Health - Cancer Tue, 15 Mar 2011 14:21:59 EST news219417595 A new method of analyzing cancerous tumors developed by scientists at Cold Spring Harbor Laboratory (CSHL) suggests that tumors may not evolve gradually, but rather in punctuated or staccato-like bursts. It is a finding that has already shed new light on the process of tumor growth and metastasis, and may help in the development of new methods to clinically evaluate tumors. http://phys.org/news219244090.html Medicine & Health - Cancer Sun, 13 Mar 2011 14:08:27 EST news219244090 Breast cancer tumors take numerous paths to resist the targeted drug Herceptin, but a single roadblock at a crucial crossroads may restore a tumor's vulnerability to treatment, scientists at The University of Texas MD Anderson Cancer Center report on line at Nature Medicine. http://phys.org/news219243699.html Medicine & Health - Cancer Sun, 13 Mar 2011 14:01:56 EST news219243699 Despite dramatically improved survival rates for childhood acute lymphoblastic leukemia (ALL), relapse remains a leading cause of death from the disease. Work led by St. Jude Children's Research Hospital investigators identified mutations in a gene named CREBBP that may help the cancer resist steroid treatment and fuel ALL's return. http://phys.org/news218899781.html Medicine & Health - Cancer Wed, 09 Mar 2011 14:20:01 EST news218899781 A UNC study released this week in the Journal of Clinical Oncology finds an increasing incidence of squamous cell carcinoma of the oral tongue in young white females in the United States over the last three decades. http://phys.org/news218813587.html Medicine & Health - Cancer Tue, 08 Mar 2011 14:20:02 EST news218813587 Combining targeted therapies might be required for maximum anti-tumor activity when treating HER2-positive breast cancers, according to two new studies by Vanderbilt-Ingram Cancer Center (VICC) investigators. http://phys.org/news218800106.html Medicine & Health - Cancer Tue, 08 Mar 2011 09:48:40 EST news218800106 Working as part of a public program to screen compounds to find potential medicines and other biologically useful molecules, scientists from The Scripps Research Institute and Massachusetts Institute of Technology (MIT) have discovered an extremely potent class of potential anti-cancer and anti-neurodegenerative disorder compounds.
