Fri, 23 Dec 2011 04:00:00 GMTResearchers from the Perelman School of Medicine at the University of Pennsylvania are in the midst of testing a personalized, dendritic cell vaccine in patients with recurrent ovarian, primary peritoneal or fallopian tube cancer – a group of patients who typically have few treatment options. Now, they have shown they can shorten the time to manufacture this type of anti-cancer vaccine, which reduces costs of manufacturing the treatment while still yielding powerful dendritic cells that may be beneficial for these and a variety of other tumor types. The data is published in the December issue of PLoS ONE.
Thu, 15 Dec 2011 04:00:00 GMTResearchers at the Perelman School of Medicine at the University of Pennsylvania report promising new results from a small clinical trial using an immune-system-based gene therapy for treating advanced stages of a deadly cancer, malignant mesothelioma. The treatment, immuno-gene therapy, transfers just enough genetic material from an existing virus to trigger a patient's innate defenses to destroy cancer cells. The study results, published in the December 15th issue of the American Journal of Respiratory and Critical Care Medicine, may lead to earlier interventions for patients using targeted therapies.
