Gene May Signal Deadly Prostate Cancer

January 12, 2010 5:30 pm 3 comments

It took a while, but researchers are honing in on a gene that could help distinguish deadly prostate cancer from the vastly more common non-aggressive prostate cancer; knowledge that could spare tens of thousand of men unnecessary treatment that is likely to leave them enjoying life less than they had hoped to. Reuters reports that scientists at Wake Forest University School of Medicine studied 4,849 men with
aggressive prostate cancer that had spread and 12,205 men with
slow-growing disease, looking at 27,000 different genetic mutations
called single nucleotide polymorphisms or SNPs. They found one that was 26 percent more common in the men with
aggressive disease. It was found in 32 percent of 4,829 men with
aggressive disease and 28 percent of 12,205 men who had slow-growing
cancers.

  • Interesting numbers but I don’t understand how the gene is 26% more prevelant in men with the aggressive disease (32%) than in men with the slow growing form (28%). I am not a statistician, but 28% from 32% is 4% and dividing 4 by 28 I get 14, so I would say in my naive way that the gene is 14% more common. Either way, I am not impressed with the predictive value of the gene involved if it occurs 28% of the time in men with slow growing cancer and 32% of the time in men with fast growing cancer. Still hard to tell into which group one would fall.
    the other item in one of the Reuters article comments is that although most of the cases are slow growing and cause no problem, it is still the 2nd leading cause of death from cancer for men in the US. So, while most cases are slow growing, the total number of cases must really by high for it to be such a killer. Now that is a scary thing.

  • Read more. I have it, have had it for 15 years according to my DR. PSA just became elevated at 65. According to the lit I have read, it is just a matter of time for all men if they live long enough. Have your prostate checked along with your PSA. Watch the numbers carefully, become aware of the other warning signs. PSA over 4 at 65 is considered a warning. But, men under 65 with PSA of .5 have been diagnosed with late stage 4, a death sentence. Read, read and act, diagnosis is not exact science yet.

  • I recently had a Prostate Ultrasound and Biopsy, (results negative). The Ultrasound/Biopsy was ordered due to my PSA levels of 5.0 (I’m 56).
    Then again, what is the “cap” or maximum number for PSA levels. (eg) If I am a 5 and the maximum number is…lets say 10, then I am at mid range. If the maximum number is 100,… then at 5 I am at the lower end. Does age, height, weight, (physical conditioning)and stress levels play into the PSA levels? I do not know for sure, but I can and will find out.
    Agreed, this is a male medical issue that needs constant attention. However, according to my study and research, No man has ever died directly from prostate cancer. Only when the cancer spreads to other organs/areas of the body, does the risk increase.
    Speaking for myself, I plan to monitor and peridocally have my prostate checked from a qualified Urologist. As it stands now, I am scheduled for another visit with my Urologist in 6 months.

    Walnuts Cut Prostate Cancer Risk

    Walnuts, of all things, appear to slow the growth of prostate cancer tumors–in mice at least. Researchers at the University of California at Davis have found that mice genetically programmed to develop prostate cancer had smaller, slower growing tumors if they consumed a diet containing walnuts. A U.C. Davis news release reports that when researchers at the school, working with colleagues at the USDA Western Regional Research Center in Albany, Calif., studied tumor size in mice fed different diets for [...]

    Research: Massage Reduces Inflammation In Tired Muscles

    Yes, it feels good, and yes, it can be pricey, but massage also does some important muscle reclamation work after a particularly tough workout. Researchers at the Buck Institute for Research on Aging at McMaster University in Hamilton Ontario conducted genetic analysis of muscle biopsies taken from the quadriceps of eleven young men after they had exercised to exhaustion on a stationary bicycle. A McMaster news release reports on the research, for which one of their legs was randomly chosen [...]

    Exercise May Slow Prostate Cancer

    The findings are preliminary, but they are also provocative: research conducted at the University of California at San Francisco suggests that men who do vigorous exercise three times a week have an increase in the expression of certain genes that are known to suppress tumors, including some breast cancer tumors that similar to prostate cancer tumors. HealthDay reports that when researchers compared prostate genes from 70 men with low-risk prostate cancer to normal prostate genes from 70 men they found [...]

    How much more does it hurt to be fat? Twenty percent, according to researchers at Stony Brook University. And that’s just if you’re overweight. Obese people hurt even more: 68 percent more for Obese 1 group, 136 percent more for Obese 2 group, and 254 percent more for Obese 3 group, as defined by the World Health Organization. A Stony Brook news release reports that when researchers at the school analyzed data about body mass index and the experience of [...]

Researchers at Northwestern University have published a study in the New England Journal of Medicine asserting that the common medical practice of focusing on the next ten years of a patient’s life has been giving people a false sense of security about their chances of having a heart attack or stroke. A Northwestern news release reports that when the scientists measured risk factors for cardiovascular disease — blood [...]

    For Back Pain, Try A Kettlebell Workout

    Kettlebells, known as “girya” in their native Russia, are basically cannonballs with handles attached to them, and they’ve been used as long as anyone can remember to train Russian athletes. Now researchers in Denmark have found something else they’re good for: pumping up core muscles so well that back pain is significantly reduced. The New York Times reports on the Danish study, in which 40 middle-aged women with back and shoulder pain were randomly assigned to one of two groups. [...]

Researchers at Stony Brook University put 33 men and women, all experienced texters, through a simple test to see how much texting would influence walking.

    The question of how much training is too much training is a tough one, but as Gina Kolata warns in her Personal Best column, it’s an important one, because overtraining is worse than under training. In fact, it can be worse than no training at all. Kolata quotes William Kraemer, a professor of kinesiology at the University of Connecticut, explaining that “People think a good workout is, ‘I am in a pile of sweat and puking.” Wrong.
