Why does docetaxel cause fluid retention?

Docetaxel causes capillary leak syndrome via albumin extravasation and vascular permeability changes unrelated to renal or cardiac causes. Cumulative dose above 400–500 mg/m2 is strongly associated. Dexamethasone 8 mg BID for 3 days starting the day before each cycle is standard prophylaxis.

When should docetaxel be stopped for fluid retention?

Grade 2 peripheral edema: continue with close monitoring and maintained dexamethasone premedication. Grade 3 edema (limiting self-care ADLs): hold docetaxel until resolution, consider dose reduction. Pleural effusion or ascites requiring intervention: discontinue.
