| アブストラクト | OBJECTIVE: Acute myeloid leukemia (AML) is the most common form of leukemia among adults in Japan. This study aimed to understand the treatment patterns, health care resource utilization, and costs of FMS-like tyrosine kinase 3 mutation-positive (FLT3m+) AML patients in Japan. METHODS: A retrospective cohort study of Japanese FLT3m + AML patients was conducted using data extracted from a national hospital-based claims database provided by Medical Data Vision Co. Ltd. (MDV; Tokyo, Japan). Patients were identified from the MDV database between April 2008 and April 2021 inclusive. RESULTS: A total of 360 patients were included in this study. The study results suggest that cytarabine + anthracyclines was the most common first-line (1 L) treatment, accounting for 41.3% of the patients. FLT3 inhibitors (FLT3i) was the most common treatment across the study period (95.7%). The mean age of patients was 62.4 years, and most were 65 years or older. The median overall survival (OS) after initiating FLT3i treatment was 394 days. The median treatment duration of FLT3i was 88.5 days, while it was 66.0 days for patients treated with FLT3i within 60 days after hematopoietic stem cell transplantation (HSCT). The overall mean monthly total treatment cost was JPY 2,009,531.7/per patient per month (PPPM) (USD 17,967.9/PPPM). CONCLUSIONS: The study found specific treatment patterns, trends and features in patients with FLT3m + AML. FLT3i was the most prescribed treatment across the study period and the overall median OS after initiating FLT3i treatment was over 1 year. The findings of this study could be helpful for clinicians to optimize treatment strategies for FLT3m + AML in Japan. |
