If your test shows you have a high PSA, that doesn't necessarily mean you have cancer. Your doctor will likely have you take another PSA test to make sure your level is higher than normal. Your doctor can also order other tests to help figure out why your PSA levels are high, such ...

Discordant prostate specific antigen test results despite WHO assay standardization. Int J Biol Markers. 2018 Aug;33(3):275-282. 摘要 介绍:总 PSA(t PSA)和游离 PSA(f PSA)是早期检 测前列腺癌最常用的生物标志物.尽管进行了标准化 工作,但目前使用的许多 PSA 检测方法可能产生不一 致的结果.在本...
Each man was sent a single invitation by letter to attend a nurse-led prostate-check clinic appointment where the potential benefits and harms of having a PSA test were explained, and written informed consent was obtained. There was a second consent form completed after 24 h for all men ...
The aim of our study is to characterize genetic determinants of PSA levels in cancer-free men in order to personalize PCa screening. We hypothesize that test accuracy may be improved by accounting for PSA variation that is due to genetic factors and does not reflect PCa.We conducted the ...
The most common screening test for prostate cancer so often returns a false positive result that it's no longer recommended for men older than 70, and it's offered as a personal choice for younger men.
“It seemed as though it would be the answer to help us identify earlier cancers,” Lepor explained. Before the PSA test, being diagnosed with prostate cancer was almost a death sentence. Now, 16 percent of men are diagnosed, but only 3 percent succumb to the disease. ...
Zlotta explained that repeat biopsy decisions are not based on a single PSA but that the new intervention might be a good idea before a repeat PSA test. Although PSA is a fairly sensitive marker for prostatic enlargement, it has poor specificity for prostate cancer. Nonmalignant conditions such...
Using the Kaplan–Meier analysis and the Log-rank test, we found that patients with hypermethylated tumours using the upstream Probe no. 1 had a significantly worse recurrence-free survival compared with patients without hypermethylation (51 vs 91%; P ¼ 0.04; Figure 5). Furthermore, we ...
Prostate-specific antigen (PSA) screening has been most commonly used for early PCa detection. When the PSA level is equal to or higher than 20 ng/ml, the serum PSA test is up to 87.2% accurate in predicting PCa4. However, owing to the organ specificity rather than the tumor specificity...
