Re: Why Do Some People Become Herceptin Resistant? (Great Article)
I have been considered resistant to herceptin from the start - that something else is driving the cancer also but we don't know what. I mentioned this pathway to my onc a while ago and she agreed its a possibility. I wonder if dna tests pick this up? I had my best result stability wise when we added the mtor inhibitor - now we re going to add perjeta - we think there is more than her2 going on.

Thanks Karen - the other one that interests me is neflinavir - seems a very promising existing drug for us to try.

Re: Why Do Some People Become Herceptin Resistant? (Great Article)
I've obviously got more than her2 going on! Good info, I've been reading a lot about IL6 and inflammatory pathways. encouraging that there are some agents out there which may be able to knowck those down.

Interesting. I am apparently one of those who isn't a herceptin responder. Just added perjeta so we will see.

Re: Why Do Some People Become Herceptin Resistant? (Great Article)
According to this article they are planning to do a clinical trial, which they say may open up early this year:

Re: Why Do Some People Become Herceptin Resistant? (Great Article)
Thanks for posting.I know Lani holds Max Wicha in high regard. It seems to be good news that we already have drugs that deal with inflammation. Lets hope the trials start very soon.
