GeneticTool Improves Estimation of Prostate Cancer Risk in Diverse Ethnic/Racial Groups

Building upon previous research, an international team led by scientists at University of California San Diego School of Medicine, has validated a more inclusive and comprehensive genetic tool for predicting age of onset of aggressive prostate cancer, a disease that killed more than 33,000 American men in 2020.

Reporting in the February 23, 2021 online edition of Nature Communications, the researchers describe the performance of a polygenic hazard score (PHS) — a mathematical estimate of an individuals’ age-specific genetic risk for developing a disease — in a multi-ethnic patient population.

“Genetic tools to predict a man’s lifetime risk of prostate cancer might allow us to target cancer screening efforts to the men who are most likely to need it. We are addressing a major public health problem and simultaneously addressing a concern that genomics and genetic tests may exacerbate health disparities because people of non-European ancestry are severely under-represented in most studies,” said principal investigator Tyler Seibert, MD, PhD, assistant professor at UC San Diego School of Medicine and radiation oncologist at Moores Cancer Center at UC San Diego Health.

A 10-Second Steam Blast: The New Weapon Against Prostate Cancer?

Vanquish® Water Vapor Ablation System, Francis Medical Steams Out Prostate Cancer The Vanquish® Water Vapor Ablation System, developed by Francis Medical, Inc. , represents an innovative approach to treating prostate cancer using water vapor (steam) to ablate cancerous tissue. This minimally invasive technique aims to target and destroy prostate cancer cells while minimizing damage to surrounding healthy tissue, potentially reducing common side effects associated with traditional treatments like surgery and radiation, Mechanism of Action:  The Vanquish system utilizes the thermal energy stored in sterile water vapor to ablate cancerous prostate tissue. During the procedure, a catheter is inserted through the urethra into the prostate, delivering water vapor directly to the targeted tissue. As the vapor condenses back into liquid, it releases stored thermal energy, effectively destroying the cancerous cells. This method is designed to respect the prostate's natural boundaries, ...

Summary Sanjay S. Timilsina , currently Lead Scientist, StataDx, a spinoff from Wyss Institute, former Postdoctoral Fellow at Harvard Medical School and the Wyss Institute at Harvard University, PhD from UTEP Department of Chemistry & Biochemistry, and XiuJun Li full Professor in the Department of Chemistry and Biochemistry and of Forensic Science, & Environmental Science and Engineering, at the University of Texas at El Paso (UTEP) have developed a new portable device for cancer detection that offers several advantages over traditional methods: Key Features: - Low cost (a few dollars per device, <8 cents per assay) - Provides results in about 1 hour (vs. 12-16 hours for traditional methods) - Approximately 10 times more sensitive than traditional methods - Portable and doesn't require specialized instruments - Can detect both CEA colorectal and PSA prostate cancer biomarkers - Uses a "paper-in-polymer-pond" structure to analyze blood samples How it works: - U...

Cancer patients and doctors team up to change how cancer drugs are tested | Fox News

Cancer patients and doctors team up to change how cancer drugs are tested | Fox News foxnews.com Associated Press For cancer patients, the harsh side effects of powerful drugs have long been the trade-off for living longer. Now, patients and doctors are questioning whether all that suffering is necessary. They’ve ignited a movement to radically change how new cancer drugs are tested, with the U.S. Food and Drug Administration urging drugmakers to do a better job at finding the lowest effective dose, even if it takes more time. Advances in treatment mean millions of people are surviving for years with incurable cancers. Jill Feldman, 54, of Deerfield, Illinois, has lived 15 years with lung cancer , thanks to that progress. Her parents both died of lung cancer months after their diagnoses. But her cancer drug causes joint pain, fatigue and mouth sores that m...
