my brother, 44 yrs old.had anastomosis in 2007 due to colon ca.went for 6cycle oral xeloda.he was on remission for 3 yrs. but had another surgery june 2010 for recurrent. had 23session of radiotherapy. after his ct scan it was found out he had multiple nodules and tumor 5x3cm in the liver. diagnosed as stage IV. he went for 6cycle of xeloda and oxiloplatin.the tumor shrink and nodules reduced. in february 2011, he was scheduled for radiofrequency ablation. however, he had another CT last week and the nodules are again multiple. the tumor increased in size after 4months from the last chemo. we are advised to see his oncologist again, for possible chemo. please tell me up front, what would be his chance to recover at least to go for the radio frequency ablation? i know that it is only palliative. but we have to try all possible options. thank you for your advise.
