Doctors could do a better job of assessing the severity of prostate cancer by analyzing changes in prostate-specific antigen(PSA) blood tests over time, a new study suggests.
Researchers from Innsbruck, Austria, report that the rate of increase in PSA, based on a factor known as velocity, can strongly predict whether a man has a high-risk form of cancer.
The researchers came to their conclusions after studying the PSA results in 426 patients who underwent prostatectomy, the removal of part or all of the prostate, and had undergone four years of PSA tests.
“Monitoring PSA velocity over time gives us valuable information that can help us better assess which tumors are slow-growing and which ones may kill,” said Dr. William J. Catalona, who is moderating a briefing on the findings slated for Tuesday at the annual meeting of the American Urological Association in San Francisco.
“Further analysis of these changes improves the specificity of the PSA test and can help us better decide when biopsy and active treatment might be necessary. It helps make PSA a smarter test.”

If you let TV ads determine what you eat, you’ll end up with huge amounts of fat and sugar but precious few vegetables and fruits in your diet.
That’s the finding of a new study that analyzes what would happen if a person were to eat 2,000 calories of foods that are advertised on the tube.
Researchers found that such a diet would include 25 times the recommended servings of sugar and 20 times the recommended servings of fat in a daily diet. But it would include less than half the recommended servings of vegetables, fruit and dairy products.
“The results of this study suggest the foods advertised on television tend to oversupply nutrients associated with chronic illness — e.g., saturated fat, cholesterol and sodium — and undersupply nutrients that help protect against illness — e.g., fiber, Vitamins A, E and D, calcium and potassium,” lead investigator Michael Mink, an assistant professor at Armstrong Atlantic State University, said in a news release.
Researchers came to their conclusions after analyzing the food advertised during 84 hours of prime-time broadcasts and 12 hours of Saturday morning broadcasts during a month in 2004.
The findings appear in the June issue of the Journal of the American Dietetic Association.
A urine test can help doctors better spot prostate cancer than either the current blood test or a rectal exam alone, U.S. researchers reported on Tuesday.
They said Gen-Probe’s Progensa PCA3 test caught about half the actual cases of prostate cancer in men who had abnormal PSA levels or digital rectal exams, and had about a 20 percent “false positive” rate.
“That’s pretty good, actually,” said Dr. David Crawford of the University of Colorado School of Medicine, who helped lead the study.
Trying to diagnose prostate cancer is one of the most maddening tasks a doctor has. The prostate is a walnut-shaped gland that produces semen and it is hard to get to.
Digital rectal exams can tell a specialist that the prostate is getting bigger, but that happens with normal aging as well as with cancer. A blood test for prostate specific antigen or PSA shows when PSA rises, but PSA goes up with either cancer or just normal enlargement of the prostate — or even if the gland is inflamed, such as from an infection.
Biopsies are difficult and painful to do and may take a portion of healthy prostate, missing any tumors entirely.
And prostate tumors can grow slowly. A study last year estimated that more than 1 million men in the United States alone had been needlessly treated for prostate tumors that likely would never have killed them.
The Progensa test looks for a genetic material called PCA3. It is a string of RNA that does not appear to have any function but that is overexpressed, or overactive, in prostate cancer.
Lightly touching the prostate can cause its release and it can then be detected in the urine using the test.
Crawford and colleagues tested Progensa in about 1,900 men who had high PSA readings, an abnormal digital rectal exam or both and who were scheduled to have biopsies.
“It reflects on the aggressiveness of the cancer,” Crawford said. “If you had no cancer your PCA3 was at 25 or 20. If you had precursors such as high grade PIN (prostatic intraepithelial neoplasia) your score was about 38 to 40 and men who had cancer scored about 50 to 55.”
The test had a specificity of 78 percent, meaning that 78 percent of the men who had cancer indicated by the test actually did. This compares to just 21 percent for PSA alone, the researchers told a meeting of the American Urological Association in San Francisco.
“If the PCA3 is abnormal, above about 35, you have got an 80 percent chance of having cancer,” Crawford said.
The test had a sensitivity of 49 percent, meaning it correctly identified 49 percent of cancers. This is far less sensitive than PSA, which catches 87 percent of tumors, but if the two tests are used together they can help rule out the need for unnecessary surgery or radiation.
Among the 1,946 men studied, 42 percent turned out to have prostate cancer.
The test was approved for use in Europe in 2006 but is not yet approved in the United States.
New research suggests that vitamins may do nothing to protect men against bladder cancer and might even raise the risk of another type of cancer.
In one study examining vitamin use, researchers analyzed more than 10,000 questionnaires that men filled out as they took part in prostate screenings.
More than 60 percent of the men said they took supplements, with 48 percent taking three or more. Multivitamins, fish oil, and vitamin C were the most common supplements that the men used.
“The high prevalence of supplement use reported in this study is of potential concern,” the study authors wrote. “Previous studies suggest an association between multivitamin use and increased risk of advanced prostate cancer,” which the earlier research had linked to men who used multivitamins seven or more times a week.
Researchers also studied 77,719 residents of Washington state, aged 50-76, who filled out surveys in 2000-2002.
Of those, 330 developed bladder cancer over the next five years. Researchers found that vitamin use didn’t lower the odds of bladder cancer.
The findings are scheduled to be released Sunday at the annual meeting of the American Urological Association in San Francisco.
“It’s really disturbing to think that so many people are taking vitamins, assuming that these pills are providing some sort of health benefits,” Dr. Mark A. Moyad, who is moderating a panel where the findings will be discussed, said in a news release. “The reality is that very little scientific research has proven vitamins to be effective in protecting against cancer.”

Researchers say they have answered a long-standing question regarding lung disease caused by cystic fibrosis: Which comes first, infection or inflammation?
“Using our model, we are beginning to answer that question, and it looks like infection does precede inflammation,” study author Dr. David Stoltz, an assistant professor of internal medicine at the University of Iowa, said in a news release from the school. “The importance of that finding is that it could dictate what types of therapy we might use. Knowing that infection is first suggests that if we can prevent or fight infection, then that might delay or prevent the lung disease in people with CF.”
Most of the deaths and disability in people with CF result from lung disease.
The findings also appear to suggest that lung infections in children with cystic fibrosis should be treated early and aggressively, Stoltz said.
The researchers reached their conclusions by studying pigs with a genetic mutation that causes cystic fibrosis.
“This is a really great example where the pig serves as a model for what happens in the human, and the pig reacts to this disease in nearly the same way,” study co-author Randall Prather, distinguished professor of reproductive biotechnology at the University of Missouri, said in the news release. “In contrast, when you use mice, they don’t get the lung disease that is common in patients with cystic fibrosis.”
The study was published online in the journal Science Translational Medicine.
The first device that uses radiofrequency energy to help control lung inflammation in adults with severe chronic asthma has been approved by the U.S. Food and Drug Administration.
The Alair Bronchial Thermoplasty System is designed for people 18 and older whose asthma isn’t controlled with medication, including inhaled corticosteroids or long-acting beta agonists.
The device delivers radiofrequency energy directly to the airways, heating and reducing the thickness of lung tissue and improving users’ ability to breathe, the agency said in a news release.
To achieve the device’s full benefit, users will require multiple sessions targeting different parts of the lungs.
The device was evaluated in a clinical study involving 297 people with severe and persistent asthma. As a condition of approval, California-based manufacturer Asthmatx Inc. must conduct additional studies to evaluate the product’s long-term safety and effectiveness, the FDA said.
Potential side effects include asthma attacks, wheezing, chest pain or tightness, partially collapsed lung, coughing up blood, anxiety, headache or nausea.
The device should not be used by people with an implanted pacemaker or defibrillator, the agency said.
The human body produces a substance similar to capsaicin — which makes chili peppers hot — at sites of pain, and blocking production of this substance can ease pain, a new study shows.
The findings may lead to the development of non-addictive painkillers, according to the researchers at the University of Texas Health Science Center in San Antonio.
In work with mice, the scientists found that a family of fatty acids called oxidized linoleic acid metabolites (OLAMs) play an important role in the biology of pain.
“This is a major breakthrough in understanding the mechanisms of pain and how to more effectively treat it,” senior investigator Kenneth Hargreaves, chair of the Department of Endodontics in the Dental School at the UT Health Sciences Center, said in an UT news release.
“These data demonstrate, for the first time, that OLAMs constitute a new family of naturally occurring capsaicin-like agents, and may explain the role of these substances in many pain conditions. This hypothesis suggests that agents blocking either the production or action of these substances could lead to new therapies and pharmacological interventions for various inflammatory diseases and pain disorders such as arthritis, fibromyalgia and others, including pain associated with cancer.”
The researchers developed two new classes of analgesic drugs that target OLAMs.
“Nearly everyone will experience persistent pain at some point in their lifetime,” Dr. Hargreaves said. “Our findings are truly exciting because they will offer physicians, dentists and patients more options in prescription pain medications. In addition, they may help circumvent the problem of addiction and dependency to pain medications, and will have the potential to benefit millions of people who suffer from chronic pain every day.”
The research was published in the Journal of Clinical Investigation.
Melanoma is an often deadly form of skin cancer. Protecting yourself from sun damage can help protect your skin.
The American Academy of Dermatology offers this list of common risk factors for melanoma:
Having fair skin or skin that is otherwise sensitive to the sun.
Having red or blond hair with blue or green eyes.
Having more than 50 moles.
Having abnormal or irregular moles, often that are typically large.
Having a history of using tanning beds or being sunburned frequently.
Having a family history of melanoma.
Having a weakened immune system.
Having a personal history of melanoma or other form of skin cancer.
Being 50 or older.
Heat therapy is effective for treating lesions caused by a parasitic skin infection that afflicts U.S. soldiers in Iraq and Afghanistan, a new study shows.
Since U.S. operations began in those countries, more than 1,300 American military and civilian personnel have developed Leishmania major skin lesions, according to information in a news release about the study.
Naomi Aronson and her colleagues at the Uniformed Services University of the Health Sciences and Walter Reed Army Medical Center looked at 56 military personal with these skin lesions and found that a single session with a ThermoMed device appeared to be as effective as the current standard therapy involving a 10-day intravenous course of sodium stibogluconate (Pentostam).
Both treatments showed comparable rates of healing. The number and severity of side effects was greater with sodium stibogluconate treatment, but those problems resolved over time with no long-term effect, according to the researchers.
The study was published in the journal PLoS Neglected Tropical Diseases.
