I have had 3 recurrences of ovarian cancer and am on my second line of chemo. What can I do to avoid recurrence after being "cured" other than taking Molecular targeted drugs? After the ovarian cancer treatment is stabilized, we have launched a targeted drug in China. You can choose this drug for maintenance treatment to minimize the recurrence of ovarian cancer. To have a good effect on ovarian cancer treatment, you need to take this drug under stable condition and this will be able to prolong the time of recurrence.
