After 3rd cycle of chemo (taxol and carbo), i did a PET scan and doctor said it wasnt safe to do surgery and tumor wasnt responding to chemo.. had 4th cycle of chemo last 4/7/26 and they added immunotherapy (keytruda)..

Ca125 was 800+ upon diagnosis in January 2026.. went down to 240 after 1st chemo then down to 148 after 2nd chemo... but after the 3rd chemo it went up to 1358.

Also getting thoracentesis and paracentesis every few weeks.

Hoping immunotherapy will help.

Hi Rikki,
As I understand it, CA 125 increases (or any cancer antigen) increases after treatment is indicative of "shedding" of cancer cells into the blood stream, caused by the treatment. That's normal.
