amrubicin and Carcinoma--Large-Cell

Amrubicin is a synthetic anthracycline drug that is a potent inhibitor of topoisomerase II. We have performed a multicenter phase II trial to evaluate the efficacy and safety of amrubicin for patients with previously treated non-small cell lung cancer (NSCLC).. Patients with advanced NSCLC who experienced disease recurrence after one platinum-based chemotherapy regimen were eligible for enrollment in the study. Amrubicin was administered by intravenous injection at a dose of 40 mg/m2 on 3 consecutive days every 3 weeks.. Sixty-one enrolled patients received a total of 192 treatment cycles (median, 2; range, 1-15). Response was as follows: complete response, 0; partial response, seven (11.5%); stable disease, 20 (32.8%); and progressive disease, 34 (55.7%). Median progression-free survival was 1.8 months, whereas median overall survival was 8.5 months, and the 1-year survival rate was 32%. Hematologic toxicities of grade 3 or 4 included neutropenia (82.0%), leukopenia (73.8%), thrombocytopenia (24.6%), and anemia (27.9%). Febrile neutropenia occurred in 18 patients (29.5%). One treatment-related death due to infection was observed. Nonhematologic toxicities were mild.. Amrubicin is a possible alternative for second-line treatment of advanced NSCLC, although a relevant hematological toxicity is significant, especially with a febrile neutropenia.

No standard chemotherapy has been established yet for large-cell neuroendocrine carcinoma of the lung. Amrubicin is active for both small cell and non-small cell lung cancers, but its activity for large-cell neuroendocrine carcinoma is still unknown.. From January 2002 to December 2009, 18 patients with previously treated advanced large-cell neuroendocrine carcinoma received amrubicin monotherapy. The efficacy and toxicity of the treatment were analyzed retrospectively.. The patients comprised 17 males and one female with a median age of 62 years (range, 51-77). Fourteen and four patients had a performance status of 0-1 and 2, respectively. Thirteen (72%) patients had received one prior chemotherapy, while the others had received two or more chemotherapies. All the patients had received platinum-based chemotherapy before the amrubicin treatment. A total of 63 cycles of amrubicin chemotherapy was administered in the 18 patients, with a median number of cycles per patient of 2.5 (range, 1-10). The median dose of amrubicin in the 63 cycles was 40 (range, 30-45) mg/m(2)/day for 3 days. Grades 3-4 neutropenia, thrombocytopenia and anemia were seen in 89, 17 and 22% of the patients, respectively. Grade 3 febrile neutropenia occurred in 33% of the patients. Non-hematological toxicity was generally mild and manageable. There were five cases of partial response, six of stable disease and six of progressive disease among the 18 patients, yielding an objective response rate of 27.7%. The median progression-free and overall survivals of the patients were 3.1 and 5.1 months, respectively.. Amrubicin was potentially active against previously treated large-cell neuroendocrine carcinoma.
