Of course I assume the pathology was drafted like mine so here goes: The size of the extension area is .3cm across at it's widest point. Very small but how far it extends cannot be specified because they did not get all of the extention. This is a very small penetration and is likely locally focal. Just for clarification, a positive margin is carcinoma to the point of where the knife made the cut. When a prostate is removed it is removed with some facia tissue and the wall of the prostate contained inside the specimen. The entire ares surrounding the prostate that is cut out is called the surgical margins. If any edge is positive then it is likely that carcinoma is on the other side of where the knife cut and still present. This does not mean that the "leftover" cancerous tissue is able to survive without the prostate gland, but rather it is possible that it has locally metastisized. You doctors seem to feel that it is so small (.3cm) that it does not as yet warrant a stage III diagnosis. They will still recommend radiating the area to be safe. And you may be done with it at that point. Good Luck and stay positive!
