Vaccine therapy for prostate cancer patients with rising PSA examined

As part of a Phase II clinical trial, adult patients with advanced prostate cancer (as evidenced by two rising prostate-specific antigen or PSA values and no visible metastasis) whose cancer is resistant to hormone therapy and had either surgery or radiation were recruited from member institutions in the ECOG-ACRIN Cancer Research Group. …

Scientists identify new, beneficial function of endogenous retroviruses in immune response

But researchers at UT Southwestern Medical Center and Karolinska Institutet in Stockholm, Sweden, found that endogenous retroviruses (ERV) also play a critical role in the body’s immune defense against common bacterial and viral pathogens. “Most scientists have become used to the view that retroviruses are generally harmful,” said Nobel Laureate Dr. …

How does prostate cancer form? Parkinson’s Link?

“Using genetic deletion we found that SIRT1 normally restrains prostatic intraepithelial neoplasia in animals. Therefore too little SIRT1 may be involved in the cellular processes that starts human prostate cancer,” said Dr. Richard Pestell, M.D., Ph.D., MBA, executive Vice President of Thomas Jefferson University and Director of the Sidney Kimmel Cancer Center. “As we had shown that gene therapy based re expression of SIRT1 can block human prostate cancer tumor growth, and SIRT1 is an enzyme which can be targeted, this may be an important new target for prostate cancer prevention.” The researchers led by Dr…

Laparoscopic surgery for bladder cancer leads to good long-term cancer control — ScienceDaily

Open radical cystectomy, or removal of the bladder though open surgery, is the treatment of choice for muscle invasive and high-risk non-muscle invasive bladder cancer; however, the surgery can lead to serious complications. Some hospitals are using minimally invasive procedures such as laparoscopic radical cystectomy, but there is little information on the effectiveness of these procedures for preventing cancer recurrence over the long term. To address this, the European Association of Urology (EAU)-section of Uro-technology has been building a large database of laparoscopic radical cystectomy procedures performed across Europe. …

Survey of the general population in France identifies knowledge gaps in the perception of lung cancer

Lung cancer management in recent years has improved patient outcomes because of screening, improved surgery and radiotherapy in early and locally-advanced stages of disease, new chemotherapies, validated maintenance therapy, and effective targeted therapies. However, fears or misperceptions about lung cancer may alter physician-patient communications and could delay lung cancer screening, diagnosis, or treatment…

New class of synthetic molecules mimics antibodies — ScienceDaily

The new molecules — synthetic antibody mimics (SyAMs) — attach themselves simultaneously to disease cells and disease-fighting cells. The result is a highly targeted immune response, similar to the action of natural human antibodies. “Unlike antibodies, however, our molecules are synthetic organic compounds that are approximately one-twentieth the size of antibodies,” said David A. Spiegel, a professor of chemistry at Yale whose lab developed the molecules…
