HIV drug blocks bone metastases in prostate cancer — ScienceDaily

“Because this work shows we can dramatically reduce metastasis in pre-clinical models, and because the drug is already FDA approved for HIV treatment- we may be able to test soon whether this drug can block metastasis in patients with prostate cancer,” says Richard Pestell, M.D., Ph.D., MBA, Director of the Sidney Kimmel Cancer Center at Thomas Jefferson University and senior author on the study. The work builds on previous research from Dr. Pestell’s lab that showed in 2012 that CCR5 signaling was key in the spread of aggressive forms of breast cancer to the lungs…

Gene associated with an aggressive breast cancer uncovered — ScienceDaily

TNBC is deadly because, unlike other types of breast cancers such as estrogen receptor (ER) positive or HER2 amplified breast tumours which have effective targeted therapy, TNBC tumours do not respond to targeted therapy. Breast cancer has many subtypes, each with its own genetic makeup. …

Gene associated with an aggressive breast cancer uncovered

TNBC is deadly because, unlike other types of breast cancers such as estrogen receptor (ER) positive or HER2 amplified breast tumours which have effective targeted therapy, TNBC tumours do not respond to targeted therapy. Breast cancer has many subtypes, each with its own genetic makeup. As such, different subtypes behave differently in invasion and metastasis. …

Immune checkpoint blockade: Powerful cancer therapy influence by genetics

“The genetic signature we have found will be invaluable to understanding the biological mechanisms that drive therapeutic responses to immunotherapy for metastatic melanoma,” says Jedd Wolchok, MD, PhD, director of the Ludwig Collaborative Laboratory and associate director of the Ludwig Center for Cancer Immunotherapy at MSK, who co-led the study with Timothy Chan, MD, PhD, of MSK’s Human Oncology and Pathogenesis Program. “Further, our strategy can now be applied to determine the genetic signatures associated with the efficacy of a number of other immunotherapies and cancers.” Few approaches to treating cancer have generated as much excitement as immunotherapy, in which the immune system is engaged to destroy malignancies. One class of such treatments targets CTLA-4, a molecule expressed on the surface of killer T cells that ordinarily blocks their proliferation…

Scientists deliver a promising one-two punch for lung cancer

Lung cancer, which affects nonsmokers as well as smokers, is the most common cancer worldwide, causing 1.6 million deaths a year, far more than pancreatic, breast and colon cancer combined. About 30 percent of the most common type of lung cancer (non-small) contains a mutation in a gene called KRAS. …

Antiangiogenic treatment improves survival rates in animal model of ovarian cancer

Now research in an animal model finds that a novel combination therapy, which couples low-dose chemotherapy with an antiangiogenic treatment, resulted in better survival rates compared with standard therapy. Led by investigators at Beth Israel Deaconess Medical Center (BIDMC) and the University of Guelph, the findings show that the agent, 3TSR, not only led to tumor regression, but also improved tumor blood flow and enabled more efficient delivery of much smaller and less toxic doses of chemotherapy. The study currently appears online in The Journal of the Federation of American Societies for Experimental Biology (FASEB) and will be published in the February 2015 print issue. …
