Home [collection] urine test for prostate cancer reveals its most aggressive forms
Clark and his team at the UK’s University of East Anglia (UEA) have been developing what they call a Prostate Urine Risk test, or PUR. Imagined as a marked improvement on standard diagnostic tools like blood tests and uncomfortable physical examinations, the technology analyzes the gene expression in urine samples and recognizes biomarker signatures of at-risk patients. It goes a little further than other urine biomarker tests under development, as it can recognize the biosignatures of different grades of prostate cancer. This enables it to assess how aggressive the cancer is and categorize it as low, intermediate or high risk. Research the team published earlier in the year revealed that PUR can predict whether patients will require treatment up to five years earlier than current methods.

Ultrasound destroys 80 percent of prostate cancers in one-year study
The new technique is called MRI-guided transurethral ultrasound ablation (TULSA) and has been under development for a number of years. The minimally invasive technology involves a rod that enters the prostate gland via the urethra and emits highly controlled sound waves in order to heat and destroy diseased tissue, while leaving healthy tissue unharmed. These waves come from 10 heating elements built into the length of the rod to treat the entire prostate gland. An algorithm controls which of these elements emit the sound waves at any one time, along with their shape, direction and strength. All of this takes place within an MRI scanner, allowing doctors to keep a close eye on which tissues are being heated and by how much. “Clinically significant cancer” was totally eliminated in 80 percent of the subjects a year after the TULSA treatment. Sixty-five percent of the subjects exhibited no evidence of cancer at all in their biopsies, while prostate-specific antigen (PSA), the key biomarker for prostate cancer, was reduced by a median of 95 percent. No bowel complications were reported, while the group reported low rates of severe toxicity, low rates of impotence and close to no incontinence (involuntary urine loss from the bladder). Additionally, the technique can be used to treat other benign conditions, such as prostate enlargement. On average, prostate volume among the study subjects decreased from 39 cubic centimeters beforehand, to 3.8 cubic centimeters following the treatment. https://newatlas.com/medical/ultrasound-destr...e-cancers-one-year-study/ |

Immunotherapy study shows how to stop cancer hiding from immune cells
T and NK cells act like the foot soldiers of the immune system, searching the body for invading pathogens and attacking them. But their activity can be regulated by other immune cells, such as mucosal-associated invariant T cells (MAIT cells), telling them when to attack and when to stand down. During the new study, the QIMR researchers discovered that if MAIT cells were switched on, they would prevent T and NK cells from attacking tumors. The tumors seem to have figured this out too – the team found that cancer cells actively turn on MAIT cells by displaying molecules called MR1 on their surfaces. “The cancer is effectively creating its own defence mechanism to evade immune attack and survive,” says Michele Teng, senior researcher on the study. “The display of MR1 activates the MAIT cells, which in turn switch off cancer-fighting T and NK cells. While other regulatory cells of the immune system are known to stop T and NK cells from killing tumor cells, this is the first time it’s been shown that these regulatory MAIT cells can do this job.” Understanding this mechanism could lead to new immunotherapy treatments. The team tested the idea in mice, by giving the animals antibodies that block MR1. Sure enough that prevented MAIT cells from switching on, increased the attack power of T and NK cells and ultimately slowed the growth and spread of the cancer [in mice]. https://newatlas.com/medical/immunotherapy-cancer-hiding-immune-cells/ |

Chemists' calculations may advance cancer prediction
Scientists' approach to cell dynamics builds new view of lifetime risk A compulational study by chemists showed the dynamics of tumor formation don't nessarily correlate with clinical data on lifetime cancer risks. It suggests biomarkers may someday be able to help predict when mutations in cells will turn cancer-prone cells into full blown cancer. https://www.sciencedaily.com/releases/2019/12/191212122554.htm ![]() |

Points to consider: is there evidence to support BRCA1/2 and other inherited breast cancer genetic testing for all breast cancer patients? A statement of the American College of Medical Genetics and Genomics (ACMG) Pal Tuya et al. Genetics in Medicine: official journal of the American College of Medical Genetics 2019 Dec
With the advances in sequencing technologies and increasing access to and expanding indications for genetic testing, it remains critical to ensure that implementation of testing is based on evidence. Currently, there is insufficient evidence to recommend genetic testing for BRCA1/2 alone or in combination with multigene panels for all breast cancer patients. https://www.nature.com/articles/s41436-019-0712-x ![]() |

Drug targeting common cancer cause enters phase 2 clinical trials
A promising new cancer drug will soon enter phase 2 clinical trials, after finding success in animal models and preliminary human studies. Known as AMG 510, the drug targets a gene mutation that’s one of the most common causes of cancer. Errors in a gene called KRAS are responsible for up to 20 percent of human cancers, particularly leukemia, colorectal, lung and pancreatic cancers. That, of course, put it squarely in the sights of scientists – but unfortunately, effective treatments have eluded them until now. The KRAS(G12C) mutation is found in about 13 percent of lung adenocarcinomas, three percent of colorectal cancers and two percent of other solid tumors, meaning AMG 510 is a promising potential treatment for those diseases.
