摘要: To examine prospectively the usefulness of measurement rate change in serum prostate specific antigen levels (PSA slope) detecting cancer a PSA-based screening study, we evaluated 982 serially screened men whose initial was negative for cancer. All had at least 1 PSA value greater than 4.0 ng./ml. and all ultimately underwent prostatic biopsy. For those who entered study with normal levels, slope cutoff point 0.75 per year or more maximized sensitivity specificity predicting (odds ratio 7.20, 95% confidence interval 4.52 to 11.47). This most predictive 70 years old younger. elevated (greater ng./ml.) lower (0.4 more) 2.73, 1.82 4.07). We conclude that is useful serial screening, although its varies patient age level.
