Genetically modified versions of patients' own immune cells successfully traveled to tumors they were designed to attack in an early-stage trial for mesothelioma and pancreatic and ovarian cancers at the Perelman School of Medicine at the University of Pennsylvania. The data adds to a growing body of research showing the promise of CAR T cell technology. The interim results will be presented at the American Association for Cancer Research (AACR) Annual Meeting 2015, April 18-22.

There are two chemotherapies commonly used to treat bone cancer in dogs: doxorubicin and carboplatin. Some dogs respond better to one drug than to the other. But until now, the choice has been left largely to chance. New work by University of Colorado Cancer Center members at Colorado State University Flint Animal Cancer Center presented today at the American Association for Cancer Research (AACR) Annual Meeting 2015 demonstrates a gene expression model that predicts canine osteosarcoma response to doxorubicin, potentially allowing veterinary oncologists to better choose which drug to use with their patients. The approach is adopted from and further validates a model known as COXEN (CO-eXpression gEne aNalysis), developed at the CU Cancer Center by center director Dan Theodorescu, MD, PhD, which is currently in clinical trials to predict the response of human tumors to drugs.

Identifying molecular changes that occur in tissue after chemotherapy could be crucial in advancing treatments for ovarian cancer, according to research from Magee-Womens Research Institute and Foundation (MWRIF) and the University of Pittsburgh Cancer Institute (UPCI), partner with UPMC CancerCenter, presented today at the American Association for Cancer Research (AACR) Annual Meeting 2015.

Mutations of the KRAS gene are commonly known to lead to cancer. However, deeper understanding of exactly how they do this continues to be explored by cancer researchers.
