UroToday – EAU 2007 – Session on Open and Laparoscopic Radical Prostatectomy Tumors
Interestingly, in prostate volumes less than 30gm, lap RP was associated with a PSM in 44%, while no such association existed for open RP.
I have never thought of this before, but a quick look at my robotic data shows that 4 of my 18 prostates that were 30 gm or less had positive margins. This 22% figure is higher than the rest for me as well compared to my 11.8% overall for T2 cancers. It may be with minimally invasive surgery the smaller prostates may be less well defined. I will pay closer attention to these in the future.
