surgery V ablation for liver mets

I am keen to hear from anyone with personal experience of either of the above.
I have just had to leave a IIstage trial of pertuzinab/herceptin after 2 very succesful years [my 3 mets are still less than 2cms a third their original size]
I have been offered a similar stage I trial with herceptin/panobinostat which I am probably going to take up but the other alternative is surgery at Christie to my liver or ablation elsewhere which to me seems less invasive but I would really like to hear from people who have had either [ablation with alcohol seems some how the most querky option] thanks xx Jan
