<< an article in June 1998 edition of Urology, comes out in favor of radical prostatectomy over using Iodine seeds on the basis of seven-year disease free rates>>

I just heard from brother Dale:

Urology magazine article reported to favor surgery over seeding. Dale just told me that he found the article in the hospital library this morning while doing rounds. It is a retrospective study .... that means researchers now going back over old records to see what they can find from histories. The report is done by Johns Hopkins. It is NOT randomized. The surgery data is from Johns Hopkins records, where they do thousands of these surgeries and do them well. (Not all surgeons are that good). The seed data is from U. of Washington, where Dale learnt seeding. It reports 90% success rates after seven years for radical prostatectomy and 78% for seeds. Note that the two data bases were not compiled by the same systems.

There are two editorial comments that say: This is very interesting and further, randomized study should be done to see whether this is in general true or whether other factors have affected these results. For example, Johns Hopkins surgeons are especially good and results at other locations may not be as good. Which age groups are patients in? Or what is the definition of success? No more cancer? OK, but how about side effects?
