Lenvatinib, an oral small-molecule multiple tyrosine kinase inhibitor (TKI), has been approved for first-line therapy for unresectable hepatocellular carcinoma (HCC). Proteinuria is one of the most common adverse events associated with lenvatinib treatment. We reported a 67-year-old Thai female was diagnosed with NASH cirrhosis and HCC BCLC B with TACE refractoriness. She received 8 mg of lenvatinib for 2 weeks and began to experience worsening hypertension, bilateral pleural effusion, pedal edema, hypoalbuminemia, hypercholesterolemia, and proteinuria. After exclusion of all possible causes, lenvatinib-induced nephrotic syndrome (NS) was diagnosed. One week after discontinuing the drug, her symptoms gradually improved. To date, there have been only a handful of reported cases of lenvatinib-induced nephrotoxicity. We report herein the case of lenvatinib-induced NS in a cirrhotic patient with HCC with resolution of symptoms in a short period after drug discontinuation. In addition, we reviewed all reported cases of lenvatinib-induced nephrotoxicity.
