Thank you. I have another question — far less fussy — if you have moment. Rob has an abdominal primary tumor. Does that mean his prognosis is worse than if the tumor was in one of his limbs? I ask because because the 50% five-year survival number gets tossed around from time to time. But that's an average. It seems to me that a patient with a pleomorphic liposarcoma in a limb has a better chance because the doctors can take out more surrounding tissue (i.e. not damage major organs). There's less room to manouvre in the abdomen. In general terms, does that mean there's a greater chance that surgery won't remove all the cancer cells?
