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. …
For years, researchers have known that a diverse group of white blood cells called myeloid-derived suppressor cells (MDSC) are more abundant in cancer patients than in healthy individuals. The cells enhance cancer growth and suppress the specialized T cells that target and destroy tumor cells…
Published in the Journal of Clinical Oncology, the study found that Herceptin, when added to chemotherapy, improved 10-year survival from 75 percent with chemotherapy alone to 84 percent with the addition of trastuzumab. Additionally, results also demonstrated continued improvement of survival without cancer recurrence — the 10-year disease-free survival rate increased from 62 percent to 74 percent with the addition of trastuzumab. Although heart problems are recognized side effects of Herceptin, the incidence rate of such events was found to be about 3 percent and the majority of those patients recovered from the initial effects. “We have found that when Herceptin is used in combination with chemotherapy, a patient’s survival is significantly improved,” said Geyer, who serves as a senior scientific advisor to the NSABP and at Massey is the Harrigan, Haw, Luck Families Chair in Cancer Research, associate director for clinical research and member of the Developmental Therapeutics research program, as well as professor in the Division of Hematology, Oncology and Palliative Care at the VCU School of Medicine. …
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…
“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…
The study – funded by Cancer Research UK, Action Medical Research and others – shows that taking an extra tumour sample at recurrence, when there are no effective therapies, could identify subsets of patients that might be treatable with existing drugs that target the genetic faults. …
The team’s ongoing work may have far-reaching implications, including new ways to treat tissue damaged during a heart attack or stroke, and even a possible cure for cancer. U.S…
“It’s really all about natural selection and survival of the fittest,” says James DeGregori, PhD, investigator at the CU Cancer Center, professor of Biochemistry and Molecular Genetics at the CU School of Medicine, and the paper’s senior author. “When you’re young, healthy cells are optimized to the surrounding tissue — they’re the ‘fittest’,” DeGregori says. …
Airplane windshields are commonly made of polycarbonate plastic or multilayer composite glass. UV-A radiation can cause DNA damage in cells and its role in melanoma is well known, according to the article. Author Martina Sanlorenzo, M.D., of the University of California, San Francisco, and co-authors measured the amount of UV radiation in airplane cockpits during flights and compared them with measurements taken in tanning beds. The cockpit radiation was measured in the pilot seat of a general aviation turboprop airplane through the acrylic plastic windshield at ground level and at various heights above sea level…
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. …
