(AP) -- Some women with very advanced breast cancer may have a new treatment option. A combination of two drugs that more precisely target tumors significantly extended the lives of women who had stopped responding to other medicines, doctors reported Friday. http://www.physorg.com/news179764255.html Medicine & Health Fri, 11 Dec 2009 14:33:10 EST news179764255 Chemotherapy generally improves survival in postmenopausal breast cancer patients, according to a landmark study led by Dr. Kathy Albain of Loyola University Health System. http://www.physorg.com/news179737360.html Medicine & Health Fri, 11 Dec 2009 07:04:22 EST news179737360 University of Florida researchers have found a way to use just a fraction of the normal dosage of a highly toxic, debilitating chemotherapy drug to achieve even better results against colon cancer cells. http://www.physorg.com/news179507396.html Medicine & Health Tue, 08 Dec 2009 15:30:05 EST news179507396 Berlin, Germany: One of the first of a series of trials to investigate the use of sorafenib - a targeted anti-cancer drug - for the treatment of advanced breast cancer has found that if it is combined with the chemotherapy drug, capecitabine, it makes a significant difference to the time women live without their disease worsening. http://www.physorg.com/news172908943.html Medicine & Health Wed, 23 Sep 2009 09:20:01 EST news172908943 Obesity is an important factor contributing to chemotherapy resistance and increasing relapse rates among children with leukemia, according to recent findings published online first in Cancer Research, a journal of the American Association for Cancer Research. http://www.physorg.com/news172845198.html Medicine & Health Tue, 22 Sep 2009 14:00:03 EST news172845198 (PhysOrg.com) -- A fiber-optic sensor created by a team of Purdue University researchers that is capable of measuring oxygen intake rates could have broad applications ranging from plant root development to assessing the effectiveness of chemotherapy drugs. http://www.physorg.com/news172838355.html Chemistry Tue, 22 Sep 2009 11:39:47 EST news172838355 Scientists at Dana-Farber Cancer Institute have uncovered the mechanism behind a promising new approach to cancer treatment: damaging cancer cells' DNA with potent drugs while simultaneously preventing the cells from repairing themselves. http://www.physorg.com/news169725288.html Medicine & Health Mon, 17 Aug 2009 10:55:26 EST news169725288 Both combination and sequential single-agent chemotherapy are reasonable options to treat metastatic breast cancer, but the choice between the two should ultimately be based on patient- and disease-related factors, according to a new commentary published online August 5 in the Journal of the National Cancer Institute. http://www.physorg.com/news168715975.html Medicine & Health Wed, 05 Aug 2009 22:40:01 EST news168715975 With a novel therapeutic delivery system, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center has successfully targeted a protein that is over-expressed in ovarian cancer cells. Using the EphA2 protein as a molecular homing mechanism, chemotherapy was delivered in a highly selective manner in preclinical models of ovarian cancer, the researchers report in the July 29 issue of the Journal of the National Cancer Institute. http://www.physorg.com/news168106425.html Medicine & Health Wed, 29 Jul 2009 18:20:01 EST news168106425 Researchers at Washington University School of Medicine in St. Louis have shed new light on a process that fixes breaks in the genetic material of the body's cells. Their findings could lead to ways of enhancing chemotherapy drugs that destroy cancer cells by damaging their DNA. http://www.physorg.com/news166986735.html Biology Thu, 16 Jul 2009 18:40:01 EST news166986735 (PhysOrg.com) -- Dana-Farber Cancer Institute scientists' discovery of a cancer-causing gene - the first in its family to be linked to cancer - demonstrates how the panoramic view of genomics and the close-up perspective of molecular biology are needed to determine which genes are involved in cancer and which are mere bystanders. The findings are reported in the June 25 issue of the journal Nature. http://www.physorg.com/news165068004.html Medicine & Health Wed, 24 Jun 2009 14:50:04 EST news165068004 The largest analysis of its kind has found that Caucasians are much more likely than people in other racial/ethnic groups to develop a rare bone and soft tissue cancer called Ewing's sarcoma. In addition, among Caucasians with this cancer, men are more likely to die than women. Published in the August 1, 2009 issue of Cancer, a peer-reviewed journal of the American Cancer Society, the study indicates that examining the gender and racial differences related to Ewing's sarcoma could provide a better understanding of the disease and could lead to improved treatments for patients. http://www.physorg.com/news164866376.html Medicine & Health Mon, 22 Jun 2009 05:30:02 EST news164866376 Six years ago, scientists announced the completion of the Human Genome Project, a historic effort to decipher each of the 3 billion letters in the genetic instruction book for our species. A single anonymous male from Buffalo, N.Y. - code name RP11 - provided the bulk of the DNA used for the project. http://www.physorg.com/news164190171.html Medicine & Health Sun, 14 Jun 2009 09:23:09 EST news164190171 A chemotherapy drug that is supposed to help save cancer patients' lives, instead resulted in life-threatening and sometimes fatal allergic reactions. http://www.physorg.com/news163691410.html Medicine & Health Mon, 08 Jun 2009 14:51:21 EST news163691410 (PhysOrg.com) -- Research from the Northwestern University Feinberg School of Medicine has found that a less toxic, solvent-free chemotherapy drug more effectively prevents the progression of metastatic breast cancer and has fewer side effects than a commonly used solvent-based drug. http://www.physorg.com/news162572989.html Medicine & Health Tue, 26 May 2009 16:10:27 EST news162572989 A research team at Northwestern University has demonstrated a tool that can precisely deliver tiny doses of drug-carrying nanomaterials to individual cells. http://www.physorg.com/news161862130.html Nanotechnology Mon, 18 May 2009 10:42:37 EST news161862130 As a breast cancer specialist, Dr. Barbara Bowers uses a whole arsenal of alternative treatments to help her patients -- acupuncture, green tea extract, vitamins, meditation and yoga, to name a few. http://www.physorg.com/news161750895.html Medicine & Health Sun, 17 May 2009 03:49:00 EST news161750895 When combined with a cocktail of chemotherapy drugs, two monoclonal antibodies, instead of one, appear to offer superior results in patients with diffuse large B-cell lymphoma, according to Mayo Clinic researchers working with the North Central Cancer Treatment Group (NCCTG). http://www.physorg.com/news161606164.html Medicine & Health Fri, 15 May 2009 11:36:26 EST news161606164 The average age of a woman diagnosed with breast cancer is 63, so it is critical to have effective proven, therapies for an older patient population. But older women with breast cancer are underrepresented in clinic trials, so there is little data on the effects of chemotherapy used in addition to other therapies such as surgery. http://www.physorg.com/news161454480.html Medicine & Health Wed, 13 May 2009 17:29:01 EST news161454480 (PhysOrg.com) -- A research group reported recently in the Proceedings of the National Academy of Sciences that they have engineered nanoparticles to help block a protein process that takes place in tumors, making the tumors more susceptible to chemotherapy treatment. http://www.physorg.com/news160829777.html Nanotechnology Wed, 06 May 2009 11:57:04 EST news160829777 (BRONX, NY) - Recurrent and metastatic endometrial and ovarian cancers can be notoriously difficult to treat: They have spread to other organs and typically have developed resistance to chemotherapy; and patients already heavily treated with chemotherapy may not be able to endure more chemo. Now, physicians at Albert Einstein College of Medicine of Yeshiva University have shown that a combination of two chemotherapy drugs not only produced clinical benefit for such patients but were also well tolerated. The findings are published online in the journal Gynecologic Oncology. http://www.physorg.com/news159558309.html Medicine & Health Tue, 21 Apr 2009 18:46:14 EST news159558309 Oncologists often have to wait months before they can determine whether a treatment is working. Now, using a non-invasive method, researchers at UCLA's Jonsson Comprehensive Cancer Center have shown that they can determine after a single cycle of chemotherapy whether the toxic drugs are killing the cancer or not. http://www.physorg.com/news158951404.html Medicine & Health Tue, 14 Apr 2009 18:10:40 EST news158951404 Researchers at North Carolina State University have successfully modified a common plant virus to deliver drugs only to specific cells inside the human body, without affecting surrounding tissue. These tiny "smart bombs" - each one thousands of times smaller than the width of a human hair - could lead to more effective chemotherapy treatments with greatly reduced, or even eliminated, side effects. http://www.physorg.com/news153668415.html Nanotechnology Thu, 12 Feb 2009 13:56:30 EST news153668415 Scientists have gained new insight into a mechanism whereby chemotherapy may actually assist the rapid regrowth of tumors after treatment. The research, published by Cell Press in the September issue of the journal Cancer Cell, also helps to explain why a combination of traditional chemotherapy with drugs that block formation of new blood vessels might impede the devastating tumor recovery that often follows cancer therapy. http://www.physorg.com/news140092884.html Medicine & Health Mon, 08 Sep 2008 11:41:24 EST news140092884 Cancer patients have complained for years about the mental fog known as chemobrain. Now in animal studies at West Virginia University (WVU), researchers have discovered that injections of N-acetyl cysteine (NAC), an antioxidant, can prevent the memory loss that breast cancer chemotherapy drugs sometimes induce. The WVU researchers' study has just been published in the September issue of the Springer journal Metabolic Brain Disease. http://www.physorg.com/news139743749.html Medicine & Health Thu, 04 Sep 2008 10:42:29 EST news139743749
