My husband has multiple lesions on his liver

Hello. My name is Melody, and my husband LaMont, who is 26, was diagnosed with Stage 4 Colon Cancer in Feb of 2009. He has gone through chemo, radiation, a few surgeries, over the past year and a half, as well as partcipating in a clinical study. We have certainly had our share of ups and downs throughout all of this, but the news we received last Mon. is very upsetting. Mont's oncologist told us that he felt none of the chemo drugs was working for him anymore. The cancer did spread a little, but his liver is taking more of beating than anything else. So, his onc-doc referred us to a surgeon who, at first, put two surgical options on the table. The first was called radioembolization. The surgeon felt this procedure was not a good option for Mont. The second is called Trans Arterial Chemo Emobilisation ( TACE). This is a more targeted therapy, where they would inject tiny beads of the chemo drug, ironetecan, directly into the vein connected into his liver. Now, according to this surgeon, this procedure will intensify the risk of liver failure. So, of course when Mont and I heard that, that scared the hell out of us. Then my husband said something, that I cannot remember now, that prompted the doctor to give another alternative. He then said, maybe he could inject small amounts of the ironetecan beads, that way it could possibly not affect the liver as much. Okay, so here is the deal. Has anyone on here ever had the TACE procedure done? And if so, has any of you had major complications? Any info you guys could share would so help. We really would like to hear from people who have been through something like this. Time is really of the essence,so, we just want to make the right decision.
