Hi Gilly
It's a tough one to call as I can appreciate. I believe there can be quite severe side effects with the ipilimumab, but I don't know anything about the mage3 one.
I have the same decision to make and I have to let the hospital know tomorrow. I have only been offered the avastin trial though as my stage is 3a and the criteria for ipilimumab is more than 8 nodes taken out (as you know) and I had 7. I didn't have anymore infected nodes, just the 1 in the SNB and that was microscopic.
The side effects with the avastin are not as severe, but the decision is still hard due to it only being a trial, the disruption to life, fitting it in around my 1 year old etc, etc. It's a bit like tossing a coin isn't it? The thing that sticks in my mind is my oncologist told me there is a very small chance (and it has happened), that taking the drug could make things worse!!!!! Great.
In the end, I think I have decided to go for it as I guess I feel that doing something is better than nothing. If your hubby does decide to accept it, he could always decide it isn't for him if the side effects are substantial. To my knowledge also (though I may be wrong here), if things were to progress to stage V, then they would stop the trial anyway and possibly offer him another one that is more suitable to that stage. Also, if he did accept the trial, I think the hospital would closely observe him and do all the scans, x-rays, blood tests etc, which if anything like the avastin trial, thye don't do otherwise.
If things did get worse, maybe you would always wonder if you took the trial, then maybe it would have delayed things, but like I said as it's only a trial, then it's hard to know for sure if they are any good.
Sorry I can't be of any more help, but as you said, you will make the decision that is right for you in the end.
I wish you both all the best and please let us know what you decide.
