Among men with at least one PSA≥2.5 ng/mL in the study, 54% (95% CI 53%, 56%) had a level dropping below this threshold by the following year. Again, results were similar for higher thresholds. When excluding men with an initial PSA-level in the trial above the threshold, the proportions of PSAs decreasing below the threshold the following year were larger: around 40% at the PSA level and 65% at the patient level. CONCLUSIONS: In a large screening trial, we show that PSA levels measured at yearly intervals fluctuate which is why an isolated PSA elevation should be repeated. This supports guidelines that abnormal PSA results should be confirmed to minimize patient worry, unnecessary biopsy and risk of overdiagnosis of low-grade cancer.
