Jeff, I hope everything has progressed well for Marc. I thought I would share my experience with you. I don't know the tumor size in my case, but the result was a left hepatic lobe resection done at NY Presbyterian April '09. The surgeon was T. Kato and he removed ~ 50% of the liver during the procedure. I should point out I was a particularly risky patient (70 years old, implanted AICD (pacer/defibrilator) and a severe heart attack survivor who had an emergency bypass and mitral valve repair done in 2001). I suffered about 35% cardiac damage, but was functioning OK after.
The procedure done by Dr. Kato went on for about 12 hours (lots of pathology breaks). I caused the surgical team some excitement by having VT (tachycardia) events during surgery, but no more permanent harm done. There was no evidence of remaining cancer from the post op pathology report, and the surgeon recommended no further treatment. However, the sharp eyed oncologist at NY Presbyterian saw comments by the pathologist that some very aggressive tissue had been removed.
In June '09 I began six months of Gemzar chemotherapy as a precautionary step.
I am now on a six month cycle of oncology followup at NY Presbyterian, and so far, have been clean.
Good luck to you in the future.
