what is the best scenario to expect after 1st chemo

I'm not a native english speaker so please excuse me if something is not understood

My father was diagnosed with HCC in December 2012 and did a resection in January 2013. At that time only a single tumor was shown in the MRI scan. Two months later the MRI scan showed at least 8 tumors of 2-2.5cm. The rest of the organs(lung, bones) look clear so far.

He is on Nexavar for 2-3 weeks and we are starting the 1st chemoembolization next week. i understand the prognosis is not good but i'd like to ask of any similar cases where patient's life was prolonged for a significant amount of time

Thank you and God bless!
