Hi Katie,
I don't know where you heard that we can only have 3 kinds of chemo, oncologists use as many chemo drugs as are necessary, to treat each recurrence of the cancer.
I've had carbo/taxol Topotecan Gemzar and now I've started Doxil. all over a 3 year period.
Good luck to your DIL.

Perhaps it's 3 lines of platinum related chemo? Please, dear readers, I'm making this up, son don't take it to heart. I just read something like that & am trying to ferret it out.
I certainly hope that isn't true because I've had 9 diffrent ones. I don't think there is any standard for how many different chemo's can be given. If the chemo's are related like Carboplatin and Cispatin, a doctor might be hesitant to give one if the other isn't effective, but your DIL should be able to try as many chemos as it takes.
