PURPOSE: We investigated the risk factors and management of pleural effusion associated with dasatinib therapy for chronic myelogenous leukemia (CML) after failure of imatinib. PATIENTS AND METHODS: We analyzed 138 patients with CML treated with dasatinib from November 2003 to January 2006 in one phase I (n = 50) and four phase II (n = 88) studies for the development of pleural effusion. RESULTS: Pleural effusion occurred in 48 patients (35%; grade 3/4 in 23 [17%]), including 29% of those treated in chronic phase (CP), 50% in accelerated phase (AP), and 33% in blast phase (BP). By multivariate analysis, history of cardiac disease, hypertension, and use of a twice-daily schedule (v once daily) were identified as factors associated with development of pleural effusions. Effusions were exudative in 78% of the assessable cases. In some patients, effusions were associated with reversible increments of right ventricular systolic pressure. Management included transient dasatinib interruption in 83%, diuretics in 71%, pulse steroids in 27%, and thoracentesis in 19% of patients. CONCLUSION: Pleural effusions occur during dasatinib therapy, particularly among patients in AP or BP. A twice-daily schedule may result in a higher incidence of pleural effusion. Close monitoring and timely intervention may allow patients to continue therapy and achieve the desired clinical benefit.
