Description

<p>A 93-year-old woman was diagnosed with lymphoplasmacytic lymphoma (LPL) with circulating tumor cells in her peripheral blood after presenting with anemia. LPL progressed eight months later, with anemia worsening and tumor cells increasing to 66% of leukocytes. She began tirabrutinib at a low dose (80 mg daily: 17% of the standard dose) because she preferred to maintain her quality of life (QOL). Within three weeks, she was free of transfusion dependency and had a partial response with the disappearance of peripheral tumor cells. The dosage of tirabrutinib was increased to 240 mg daily because it was well tolerated. She has been on the treatment for 13 months with no adverse effects. Tirabrutinib, a highly selective Bruton’s tyrosine kinase inhibitor, has been reported to have promising efficacy for LPL, but it also has a high incidence of dermatological toxicity, which may impair QOL. Low-dose tirabrutinib initiation may be effective and assist elderly patients with LPL in maintaining their QOL.</p>
