Simple graphic method for estimation of prostate-specific antigen doubling time.
The prostate-specific antigen doubling time (PSADT) is of prognostic value in patients with prostate cancer, but computerized algorithms are usually required for PSADT estimation. We present here a simple graphic tool that can be used to estimate the PSADT on the basis of two increasing PSA measurements, separated by 3 to 12 months.
