Abstract:
In patients with a normal digital rectal examination and serum PSA levels under 18.4 ng/ml Yang (i.e. under 10.0 ng/ml Hybritech or under 14.4 ng.ml with the Basel Cantonal Hospital assay), twice yearly then yearly follow-up examinations are sufficient. More closely spaced examinations and a transrectal ultrasound scan are appropriate in patients with abnormalities upon digital rectal examination, especially when serum PSA levels are consistently elevated.
