High pretreatment PSA velocity predicts worse outcome

The most significant single predictor of aggressive prostate cancer is an elevated rate of increase in prostate specific antigen (PSA) levels, according to a new study.

Laparoscopic radical prostatectomy with robot technology can improve survival rate for prostate cancer patients

Performing less invasive laparoscopic surgery using robotic technology may improve survival rates for prostate cancer patients, according to a study by urologic oncologists at Thomas Jefferson University Hospital's multidisciplinary Genitourinary (GU) cancer center.

Study breaks link between lycopene and prostate cancer prevention

Tomatoes might be nutritious and tasty, but don't count on them to prevent prostate cancer.

EPCA-2 testing more accurate way to identify cancer in the prostate

New studies of a blood protein recently identified at Johns Hopkins, early prostate cancer antigen-2 (EPCA-2), may change the way men are screened for prostate cancer - a disease that kills tens of thousands of men every year.

New diagnostic technologies to predict and monitor cancer risks

Molecular messages and signals circulating in blood or contained in cells lining the airway can identify early stage cancer, according to research reported at the 2007 Annual Meeting of the American Association for Cancer Research.

PSA doubling time and indicator of recurrent prostate cancer

A detectable level of prostate-specific antigen (PSA) is the first indicator of recurrent prostate cancer after radical prostatectomy.

Researchers assess the accuracy of using PSA to predict prostate cancer outcome

The amount of prostate-specific antigen (PSA) in a man's bloodstream at the time of his prostate cancer diagnosis or its rate of change over the course of the disease does not adequately predict lethal prostate cancer, according to a study in the April 4 Journal of the National Cancer Institute .

Regular health exams increase likelihood that older adults will get recommended cancer screenings

If you're 50 or older, seeing your doctor every year or two for a checkup may be a good defense against cancer, according to a new study by researchers at UC Davis, the University of Washington, and Group Health Cooperative in Seattle.

Biopsy may underestimate prostate cancer in overweight men

Obese and overweight men who are diagnosed with prostate cancer by biopsy are more likely than healthy weight men to actually have a more aggressive case of the disease than the biopsy results would indicate, according to a study led by a Duke University Medical Center researcher.

Obesity at the time of prostate-cancer diagnosis dramatically increases the risk of dying from the disease

Obese men who are diagnosed with prostate cancer have more than two-and-a-half times the risk of dying from the disease as compared to men of normal weight at the time of diagnosis, according to a study by researchers at Fred Hutchinson Cancer Research Center.

Green tea and COX-2 inhibitors combine to slow growth of prostate cancer

Drinking a nice warm cup of green tea has long been touted for its healthful benefits, both real and anecdotal. But now researchers have found that a component of green tea, combined with low doses of a COX-2 inhibitor, could slow the spread of human prostate cancer.

New way to identify which men need a second prostate biopsy

A researcher in the Oregon Health & Science University Cancer Institute and Portland Veterans Affairs Medical Center has found a way to identify which men need a second prostate biopsy because they may be harboring life-threatening prostate cancer even though they were given a clean bill of health after their first biopsy.

Testosterone replacement therapy appears to be safe - has little effect on the prostate gland

Preliminary research suggests that testosterone replacement therapy for men with low testosterone levels appears to have little effect on the prostate gland, contrary to some reports that this therapy may be harmful, according to a study in the November 15 issue of JAMA: The Journal of the American Medical Association.

Link between common lifestyle factors, immune system and cancer

The immune system is fickle, and easily influenced by more than just viruses and bacteria. It can be swayed by the seemingly unexpected, such as by what we eat, for example, and affected by surprising sources.

Muscle protein myosin VI involved in the development of prostate cancer

Researchers at the Johns Hopkins Kimmel Cancer Center have for the first time implicated the muscle protein myosin VI in the development of prostate cancer and its spread.

PSA blood tests for prostate cancer should start earlier in life

A study has found that measuring prostate specific antigen (PSA) in the blood may be the best way of identifying men with life-threatening prostate cancer.

2 Nov 2006

Lower PSA in obese men could be a warning

Researchers in the U.S. say that obese men have lower levels of a protein used to screen for prostate cancer risk, and doctors should take weight into account when determining a man's risk.

Carbon nanotube amplification strategies for highly sensitive immunodetection of cancer biomarkers

In an attempt to increase the sensitivity of cancer biomarker detection and to decrease the need for large samples from which to detect those molecules, a multi-institutional research team has shown that a "forest" of single-walled carbon nanotubes can be used to detect lower levels of the prostate specific antigen (PSA) than is possible using the current commercial assay.

Aspirin may improve men's urinary health and prevent enlarged prostate

Researchers suggest that taking nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin or ibuprofen may improve men's urinary health.

Mayo clinic finds NSAIDs may prevent or delay enlarged prostate

Mayo Clinic researchers have found that taking nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin or ibuprofen may prevent or delay benign prostatic hyperplasia.
