RE: Visually Guided Transrectal HIFU for Prostate Cancer: Prelim Report

[Guest guest]

This is a small, very short term study,

and I found this bit of the report a bit confusing - perhaps I didn’t

fully understand it:

<snip> At 6 months the negative

biopsy rate was 66.1%. There was no biochemical evidence of disease in 71.9%

overall. <snip>

If the negative biopsy rate was 66.1% at

six months, does that mean that the positive biopsy rate was 33.9% and that one

third of the men treated were still found to have cancer cells in their

prostates six months after treatment?

But if this is the case then why was there

no biochemical evidence of disease in 28.1% of cases? Did the ‘missing’

5.8% of the men have cancer cells that failed to generate enough PSA to meet

the criteria for biochemical failure?

And this is regarded as a favourable

outcome? What would an unfavourable outcome be?

All the best

Visually Guided Transrectal HIFU for Prostate Cancer: Prelim Report

High intensity focused ultrasound is a minimally invasive treatment

option for prostate cancer. Data from the literature show promising early

oncological outcomes and a favorable side effect profile. This study is a

preliminary report of the Italian experience (Perugia

and Turin) of

patients treated with the Sonablate*500 high intensity focused ultrasound

device.
