From Brexit to TRexit: Transperineal biopsies pose a challenge to the traditional transrectal biopsy method
By now most of us are familiar with Brexit, the UK’s pending divorce with the European Union. But in a play on that term, British doctors are also moving towards an exit they’ve dubbed “TRexit” from the most common sort of prostate biopsy: the transrectal ultrasound guided biopsy, or TRUS.
Men who test positive on the PSA cancer screening test will usually have a prostate biopsy that’s performed in either of two ways. With a TRUS, doctors guided by an ultrasound machine can sample the prostate using a biopsy needle inserted through the rectum. Alternatively, the biopsy needle can be inserted (also under ultrasoun...

New Infrared Chemical Imaging Method to Diagnose Cancers
Prostate cancer can be very difficult to diagnose, with way too many patients undergoing surgeries that turn out to be unnecessary. Now, researchers at Purdue University, Boston University, and the Chinese Academy of Sciences have developed an infrar...

Fight Aging! Newsletter, July 8th 2019
In this study, we identify a link between members of the genus Veillonella and exercise performance. We observed an increase in Veillonella relative abundance in marathon runners postmarathon and isolated a strain of Veillonella atypica from stool samples. Inoculation of this strain into mice significantly increased exhaustive treadmill run time.
Veillonella utilize lactate as their sole carbon source, which prompted us to perform a shotgun metagenomic analysis in a cohort of elite athletes, finding that every gene in a major pathway metabolizing lactate to propionate is at higher relative abundance postexercise. Us...

First Cryopreservation Following Use of Assisted Death Legislation in California
Simple human dignity and self-ownership demands the right to end one's own life on one's own terms, and to be able to help others achieve this goal where they are not capable of doing so themselves. Yet these acts remain forbidden to most people in most parts of the world. Painless, effective euthanasia requires medical assistance, and providing that service remains largely illegal. This state of affairs is slowly starting to change in the US, however, and so late last year the first cryopreservation following voluntary euthanasia took place.
Cryopreservation is the only presently available end of life option that o...

Liquid Biopsy for Prostate Cancer Uses Urine as the Specimen
There have been lots of new developments in the world of the liquid biopsy and I have blogged about some of the most recent (see, for example:Grail Picks Specific Method for Liquid Biopsy Clinical Trials;Study Concludes That Liquid Biopsies Can Help Guide Cancer Treatment). However a recent article caught my attention because it involved urine as the required specimen rather than blood and also involvedexosomes which are extracellular vesicles (EVs) produced in the endosomal compartment of most eukaryotic cells as well as cancer cells (see:Bio-Techne nets FDA breakthrough ticket in prostate cancer liquid biopsy). Exo...

Using MRI for Prostate Cancer Detection Increases Diagnosis Rate
Using magnetic resonance imaging in tandem with the traditional ultrasound method can significantly improve prostate cancer detection, according to a study recently published inJAMA Surgery.Prostate cancer has been traditionally diagnosed with only ultrasound. Physicians use the technique for tissue biopsy. However, this method alone can ’t detect certain tumors. Historically, MRI-based biopsy practices are practical because they can detect precise lesions on the prostate. Yet, not all tumors appear on MRI, making it difficult to identify all kinds of cancer. Researchers from the University of California Los Angeles fo...

Can a man with abnormal PSA and a negative diagnostic MRI avoid a prostate biopsy? It ’s debatable
Not long ago, an abnormal PSA reading would be followed right away by a standard biopsy to search for potential cancer in the prostate. During such a procedure, doctors take 10 to 12 samples of the prostate from various locations while looking at the gland with an ultrasound machine.
These days, however, men with high PSA levels during cancer screening might be offered a specialized imaging test first. Called a multiparametric magnetic resonance imaging (mpMRI) scan, it’s particularly good at visualizing cancer in the prostate and distinguishing high-grade tumors that need immediate treatment from low-grade tumors that d...

Molecular Motors Drill Through Cancer Cells
A couple of years ago a team of U.S. and U.K. scientists came up with a way of making molecular motors that can drill through cancer cells, destroying them in the process. The researchers, from Rice University, Durham University, and North Carolina S...

Highly accurate test reveals recurring prostate cancer
After being treated for prostate cancer, some men will experience a rise in PSA levels suggesting that new tumors lurk somewhere in the body. Finding these tiny cancerous deposits before they grow and spread any further is crucially important. But it’s also a challenge, since the budding tumors might be too small to see with standard tools such as magnetic resonance imaging.
Now scientists in California have published results with an experimental imaging technique that detects recurring prostate cancer with the best accuracy reported yet. Importantly, some of the unveiled tumors were “still curable with targeted radiat...

Phytonutrients: Paint your plate with the colors of the rainbow
Did you know that adding color to your meals will help you live a longer, healthier life? Colorful fruits and vegetables can paint a beautiful picture of health because they contain phytonutrients, compounds that give plants their rich colors as well as their distinctive tastes and aromas. Phytonutrients also strengthen a plant’s immune system. They protect the plant from threats in their natural environment such as disease and excessive sun.
When humans eat plant foods, phytonutrients protect us from chronic diseases. Phytonutrients have potent anti-cancer and anti-heart disease effects. And epidemiological research sug...

Screening elderly men for prostate cancer: More harm than good?
Most men diagnosed with prostate cancer don ’t die of the disease. Between 2011 and 2015, 112.6 per 100,000 men per year were diagnosed with prostate cancer in the U.S., but only 19.5 per 100,000 men per year died of the disease over that same period of time. That is still far too many deaths. But […]Find jobs at Careers by KevinMD.com. Search thousands of physician, PA, NP, and CRNA jobs now. Learn more.

African American men respond better to treatments for advanced prostate cancer in clinical trials
Racial differences have long been evident in prostate cancer statistics. In particular, African American men are diagnosed with prostate cancer more often than white men, and they’re also nearly twice as likely to die of the disease.
But new research also shows that African American men who receive the most advanced treatments for late-stage prostate cancer can live at least as long — or even longer — than their Caucasian counterparts.
Why is this the case? Scientists are searching for an explanation. “The fact that African American men have better survival is of huge research interest,” said Dr. Stephen Freedlan...

Last Couple of Months in Oncology with Dr. Bishal Gyawali: March 2019
By BISHAL GYAWALI MD, PhD
Hey, I’m back!
Well, you might not have noticed that my blogs were missing for the last three months but anyways, its good to be back. I was having a little time off blogs and social media as I was transitioning in my career but now I am back. Sometimes, it is very difficult to manage time for things that you must do versus things you enjoy doing, especially when these two don’t intersect. For me, these last few months the things I had to do were all bureaucratic while I couldn’t find the time for things I enjoy doing like writing these blogs. But now that we are back, let’s rec...
