Her Dr may be suggesting that she stay on chemo to keep the cancer from wanting to grow. I have never been on caelyx but have been on Doxil with fairly good results.
You might want to ask her Dr but I am sure that is the reason that he wants to keep her on chemo, more as a precautionary measure.

Many women on this forum have taken .. or are taking .. Doxil. With a CA of 9, I am surprised with more chemo. Did she have a CT or PET that showed new cancer activity?
