Fluid Retention After FOLFIRI: What the Evidence Shows

Yes, fluid retention can result from FOLFIRI chemotherapy. Here's what's specific to your situation:

FOLFIRI and Fluid Retention

FOLFIRI (a combination of fluorouracil, leucovorin, and irinotecan) can cause:

Irinotecan may affect kidney function and fluid balance
Fluorouracil can damage blood vessel walls, allowing fluid to leak into tissues
Both drugs can trigger inflammation that leads to swelling

Fluid retention typically appears during treatment or within weeks after your final dose.

Ascites Specifically

Ascites means fluid buildup in your abdomen. It can happen with colorectal cancer treatment, but the cause matters:

Direct effect from chemotherapy drugs
Liver function changes
Inflammation from treatment
Sometimes related to the cancer itself

What Your Oncology Team Needs to Know

Report to them:

When the swelling started (during treatment or after?)
How much your abdomen has swollen
Any weight gain (sudden gains suggest fluid)
Shortness of breath or belly discomfort

They'll likely check:

Liver and kidney function (blood tests)
Possibly imaging to measure fluid amount
Heart function (if significant)
