Ascites, antibiotics

[u/Few-Hat6577]

After 2 1/2 months maintenance drug, CA 19-9 slowly up, and plus after 4 rounds of Gemzar/Cisplatine failed, it developed a small to moderate amount of ascites. Since I had low grade fever and white blood cells high, my oncologist prescribed an antibiotic. After antibiotics taken, the ascites stayed and did not getting worse. The morning weight stayed about same. My appetite is okay and still walk 2000-4000 steps daily. I have no liver metastasis and liver function and numbers are good. The day before yesterday, I started 1st round of Irinotecan/Fluorouracil. Any of you have the similar situation?
