This seems to be a promising development -- It seems the cells which don't respond to platinum chemo drugs also don't produce the protein marker CA 125 that's used to indicate presence or absence of ovarian cancer. That means early recurrence after what seems to be totally successful front line treatment may be growth of those cells that aren't evident after treatment because they don't produce CA 125. However, it doesn't explain why my CA 125 numbers have soared during this early recurrence--that would indicate that the cells producing CA 125 weren't entirely wiped out by the front line treatment. Cancer works in mysterious ways.
What seems promising is there may be a drug that causes those particular CA 125-free cells which ignore platinum drugs to stop ignoring platinum drugs.
I'll just keep my fingers crossed, I guess.
