Dear Lilya
The NICE guidelines I found (CG58 - Prostate Cancer Diagnosis and
Treatment) seems to skirt around the issue of PSA screening or case
finding but starts at the decision to have a biopsy!
"To help men decide whether to have a prostate biopsy, healthcare
professionals should discuss
with them their prostate specific antigen (PSA) level, digital rectal
examination (DRE) findings
(including an estimate of prostate size) and comorbidities, together
with their risk factors
(including increasing age and black African and black Caribbean
ethnicity) and any history of a
previous negative prostate biopsy. The serum PSA level alone should not
automatically lead to
a prostate biopsy."
Is there another guideline on PSA? I also note this was February 2008 -
and the 2 large RCTs of screening published in March 2009.
Seems guideline writers have an uphill battle keeping long guidelines up
to date!
Thanks
Paul Glasziou
