The well-studied protein VEGF does not appear to have any prognostic or predictive value for men with locally advanced prostate cancer, researchers from the Department of Radiation Oncology at Thomas Jefferson University Hospital and other institutions found in a retrospective study published online April 25 in the journal BMC Radiation Oncology. http://medicalxpress.com/news/2013-04-vegf-relevant-biomarker-advanced-prostate.html Cancer Mon, 29 Apr 2013 14:46:52 EST news286465601 A monoclonal antibody targeting a protein known as SFPR2 has been shown by researchers at the University of North Carolina to inhibit tumor growth in pre-clinical models of breast cancer and angiosarcoma. http://medicalxpress.com/news/2013-04-monoclonal-antibody-inhibits-tumor-growth.html Cancer Fri, 19 Apr 2013 15:10:01 EST news285602419 Pancreatic cancer is a deadly disease with increased incidences in the recent years. According to NDSU researchers, epidemiological data show chronic stress in a negative social and psychological state such as depression might serve as a risk factor for cancer development and progression. However, the underlying biological mechanisms are not well understood.  http://medicalxpress.com/news/2013-02-link-stress-pancreatic-cancer-paper.html Cancer Fri, 15 Feb 2013 10:40:02 EST news280143750 A study led by Dr Josep Tabernero, the Director of Clinical Research at the Vall d'Hebron Institute of Oncology (VHIO) and Head of the Medical Oncology Department at the Vall d'Hebron University Hospital, shows for the first time that ribonucleic acid interference (RNAi) is effective in the treatment of cancer patients. Harnessing these molecules to silence genes involved in the development and growth of cancer cells is an important step forward in developing a new and more targeted type of cancer therapy. http://medicalxpress.com/news/2013-02-first-in-man-therapeutic-effect-rnai-gene.html Cancer Mon, 11 Feb 2013 08:46:49 EST news279794788 A new Investigative Ophthalmology & Visual Science (IOVS) article reveals that increasingly aggressive therapies that block VEGF could cause damage in treating eye diseases. Scientists discovered inhibiting anti-VEGF might have a harmful effect on the tissue responsible for producing the fluid that bathes the eye, medically termed the ciliary body. http://medicalxpress.com/news/2013-01-eye-diseases-anti-vegf-therapies-side.html Ophthalmology Fri, 11 Jan 2013 14:43:51 EST news277137799
