1、 不同年龄组良性前列腺疾病患者 血清PSA的检测及意义 摘要目的:探讨良性前列腺疾病患者血清前列腺特异性抗原(PSA)与年龄的关系。方法:采用酶联免疫法对242例4079岁的良性前列腺疾病患者进行PSA测定。结果:不同年龄组其血清PSA水平不同,各组上限值为:4049岁组2.50 g/L,5059岁组3.49 g/L,6069岁组4.57 g/...

For the different age groups the number needed to screen to avoid one biopsy varied between 9.2 (≤49 years) and 17.4 (50-59 years).With "new", fine-tuned PSA cut-offs we detect all relevant PCa with a significant reduction of biopsies compared to the "old" cut-off values. ...
Since PSA levels in healthy men increase with age, we compared PSA levels of the two populations within specific age groups. Fig. 1 shows geometric mean PSA levels for Japanese men in the United States and in Japan, by 10-year age group, with age groups 40–49 years and 50–59 years ...
Several factors may cause your PSA levels to vary, such as: Your age Your general health condition Your personal and family medical history The size of your prostate (for instance, BPH is an enlargement of the prostate gland that happens in many people as they get older, and it can also ...
Differences in total PSA (tPSA) levels between age-matched African-American and white men have been reported by several groups. Age-specific cPSA levels, however, have not been thoroughly evaluated and reported among African-American populations. Methods We prospectively evaluated the serum cPSA, t...

Calculations were made adjusting for PSA levels. Results: PSA-testing rate in the general population was 21.6/1000 person-years. In the age-group 55–69 years, this rate was 86.8/1000 (152.6 in men >70 years). Referral rates were 67.9 and 39.5% for men with PSA 4–10 and >10 ng/...
Men with PSA below the median experienced low 30-year absolute risk for developing lethal prostate cancer across age groups (40-44, 0.19%; 45-49, 0.51%; 50-54, 1.62%; 55-59, 0.59%). “These findings do not necessarily imply that p...
tPSA levels had significant difference between the groups with BPH and PCa, but their prostate volumes had no significant difference.Conclusions:PSA is an important tumor marker for prostate cancer.Prostate biopsy is an effective method in the diagnosis of prostate cancer. 展开 ...
