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…

Pathway that degrades holiday turkey fuels metastasis of triple negative breast cancer — ScienceDaily

“I’m not saying that people with metastatic breast cancer shouldn’t eat turkey during the holidays, but triple-negative breast cancer appears to have found a way to process tryptophan more quickly, equipping cancer cells to survive while in circulation, which allows them to metastasize,” says Thomas Rogers, the paper’s first author and PhD candidate in the laboratory of CU Cancer Center investigator, Jennifer Richer, PhD. …

Prostate Cancer: Watchful waiting isn’t right for everyone — ScienceDaily

“We know that African American men have more aggressive prostate cancer than Caucasian men,” says Kosj Yamoah M.D., Ph.D., Chief Resident, Department of Radiation Oncology at Thomas Jefferson University. “Our study shows that African American men who are diagnosed with a low-grade cancer at first — the cancers that are sometimes watched rather than treated — are more likely to develop aggressive disease sooner than Caucasian men.” Dr. Yamoah, together with Timothy Rebbeck and colleagues from the University of Pennsylvania, looked at patients whose cancers were low to intermediate grade and who underwent surgery to remove all or part of their prostate. The surgery was important because often men are given a so called “biopsy” Gleason score of cancer severity based on 12 needle biopsies of the prostate gland…

Genomic analysis of prostate cancer indicates best course of action after surgery — ScienceDaily

“We are moving away from treating everyone the same,” says first author Robert Den, M.D., Assistant Professor of Radiation Oncology and Cancer Biology at Thomas Jefferson University. “Genomic tools are letting us gauge which cancers are more aggressive and should be treated earlier with radiation, and which ones are unlikely to benefit from additional therapy.” Although surgery for prostate cancer is meant to be curative, in some men, the cancer can regrow. Doctors have developed high risk criteria based on clinical factors, but these criteria are imperfect predictors of cancer returning, or recurrence. Only about 50 percent of high risk patients ever go on to develop metastases, raising the question of whether those who receive additional therapy are being overtreated. …

New program makes prostate cancer treatment decisions easier

A recent clinical study published in the New England Journal of Medicine showed that mortality rates for early stage prostate cancer were the same for men who choose active surveillance such as periodic PSA testing and biopsy, versus those who chose to treat their disease immediately with radiation or surgery. The research suggested that in cases of low-risk prostate cancer, aggressive treatment may not offer a long term survival benefit, and yet is associated with a number of side effects such as urinary incontinence and sexual problems. However, the vast majority of men diagnosed with low-risk cancer undergo aggressive treatment rather than active surveillance…

Prescription painkiller deaths up 261 percent in NYC

New York City health officials say deaths from prescription painkillers such as Oxycontin and Vicodin increased 261% between 2005 and 2011. The city Health Department says there were 220 such deaths in 2011, up from 130 in 2005. The biggest increase was on Staten Island. There were 40 painkiller deaths there in 2011, or 11.2 per 100,000 people.  The Health Department plans to hold two conferences for doctors and dentists on Staten Island next month to address the problem. Health Commissioner Dr. Thomas Farley said Tuesday that prescription opioid painkillers are chemically similar to heroin and can lead to addiction and fatal overdose. He said doctors and patients should know the dangers of using the drugs.
