This study was conducted to evaluate the efficacy of amrubicin as first-line chemotherapy for elderly and poor-risk patients with extensive-disease small-cell lung cancer (ED-SCLC).
Untreated SCLC patients who were > 75 years of age or had a performance status of 2 or more were eligible. Amrubicin (35 or 40 mg/m(2) on days 1-3 every 3 weeks) was administered.
Between January 2003 and May 2009, 27 patients were evaluated. The median number of treatment cycles was 4 (1-6). Grade 3 or 4 hematologic toxicities comprised neutropenia (63%), leukopenia (56%), thrombocytopenia (15%), and anemia (19%). Febrile neutropenia was observed in four (15%) patients. No treatment-related deaths occurred. The nonhematologic toxicities were mild. The overall response rate was 70%. Progression-free survival, median survival time, and the 1-year survival rate were 6.6 months, 9.3 months, and 30%, respectively. The 40 mg/m(2) dose was feasible and had a tendency to be more effective than the 35 mg/m(2) dose.
Amrubicin exhibits activity and acceptable toxicities for elderly and poor-risk patients with ED-SCLC in the first-line treatment setting.
