Thanks for your responses, it's very much appreciated.
Just wanted to give a bit of an update... We met with the trial team, and provided Dad gets through all the testing (heart, liver, kidney's etc) - he's going to be admitted into the PENAO trial towards the end of this month. The doctor advised that they had done molecular testing on dad's resected tumour however no mutations were found. They seem to have had positive results in maintaining stable disease with this trial thus far - so hopefully we achieve the same. Essentially from my understanding PENAO is the second generation of the GSAO drug (but significantly more potent), that aims to inhibit glucose update and blood supply to tumours. The layman's translation about the drug by the doctor is that it's an organic form of arsenic - very interesting!
I raised the possibility of SIRT with the trial doctor and he too agreed that it should be considered as a legitimate option - however after consulting with his oncologist she advised that it wasn't for him. Not sure on the specifics of this however...
Theresa, thanks very much for that information - it's good to know that there are options out there. Will definitely keep that in mind, if things don't go well with this trial.
Ilias, can definitely understand where you're coming from... I think given this disease isn't very prominent here in Australia that the doctors just generally don't have much in the way of 'next step options' - especially when you're on a site such as this and you see the breadth of treatment options available around the world, we seem quite limited here.
On the positive side, Dad's still treating each day like a normal one and doesn't have any ill effects at all... I think he feel's better when he's receiving treatment as you feels like he's doing something about it rather than sitting around waiting for things to get worse.
Will be sure to keep you all posted on how it all goes.
