DRE is useless for follow up of prostate cancer patients
Certainly from the prostate cancer point of view, I have to agree
with Des Spence. With increasing use of PSA (prostate specific antigen), I
agree that the role of DRE as a prostate cancer screening tool is almost
As regards DRE as a follow up tool, in prostate cancer patients
treated by radiotherapy, a Royal Marsden study found that DRE fails to
detect any local recurrences in the absence of a rising PSA (1).
Similarly, a literature review found that after prostatectomy a PSA
increase reliably preceded disease recurrence, making digital rectal
examination superfluous to requirements (2).
Further more, results of DRE could be inconsistent. A study from San
Antonio found that approximately 70% of abnormal DREs were normal the
following year even in patients with prostate cancer (3).
Evidence, not dogma, should guide our Clinical practice.
