New York, NY - Researchers at Memorial Sloan-Kettering Cancer Center have found that change in PSA levels over time — known as PSA velocity — is a poor predictor of prostate cancer and may lead to many unnecessary biopsies. The new study of more than 5,000 men was published online ...
In general, the goal is to keep the PSA levels as low as possible or to achieve a significant decrease in PSA levels over time. However, the specific target levels may differ based on individual circumstances and treatment goals. For example, after surgery or radiation therapy, the target PSA...
PSA levels can be confusing. They can go up and down for no obvious reason. They can rise after treatment. And levels tend to be higher in older men and those with large prostates. Plus, the PSA blood test isn't precise. That's why doctors watch your results over time instead of foc...
Many abnormal PSA test results normalize over time.The article presents a study of the prostate-specific antigen (PSA) levels of men previously enrolled in a dietary intervention trial to reduce the recurrence of colon polyps. PSA is used for prostate cancer screening. Positive screening values ...
A PSA test can determine if you have high levels of PSA in your blood. Normally, PSA is produced and released within the prostate gland, where it helps make semen and plays an important role in fertility. Only small amounts of PSA move out of the prostate and into the blood in healthy...
PSA doubling time can be an indicator of biochemical and clinical progression of prostate cancer. This "Urology PSA Calculator - Prostate Cancer Evaluation" app predicts the changes in PSA levels over time. The PSA-age volume (PSA-AV) score was calculated by multiplying the age and prostate ...
The PSA level tends to rise in men with benign prostatic hyperplasia (BPH) and is a good marker for prostate volume. PSA levels are usually elevated in men with acute bacterial prostatitis. The most valuable measurement of PSA is its change over time rather than the actual serum level. No ...
men with elevated PSA levels and no other symptoms were sometimes prescribed antibiotics to see if an infection might be causing the PSA increase. However, according to the American Urological Association, there is no evide...
Using specific risk-based parameterizations of this screening simulation model, we search for improved PSA-based PCa screening strategies for certain well-known risk groups based on race (white and African American), family history of PCa, and different levels of comorbid medical conditions. 展开 ...
Results were not altered upon stratifying the sample between men who developed prostate cancer during the course of the study and those who did not.Results from this study indicate that chronic use of aspirin, other NSAIDs, or statins did not affect PSA levels or PSAV in men at high risk ...
