中文摘要: 目的 探索真实世界中氟马替尼一线治疗老年初发慢性髓系白血病的有效性及安全性,为临床用药提供依据。方法 回顾性选取2020年6月至2024年6月安徽理工大学附属医院收治的48例老年初发慢性髓系白血病患者为研究对象,年龄(72.61±5.03)岁,44例(91.67%)合并非血液系统基础疾病,氟马替尼口服,600 mg,1次/d,收集治疗3、6、12、18个月时的血液学、细胞遗传学和分子学反应(MR)及安全性指标,随访至2024年9月30日,统计患者的无事件生存(EFS)率和总生存(OS)率。结果 治疗3个月时,95.83%(46/48)患者达完全血液学反应(CHR),6个月100%(43/43)达CHR;3、6、12个月早期分子学反应(EMR)率分别为82.61%(38/46)、92.86%(39/42)、100%(34/34);3、6、12、18个月主要分子学反应(MMR)率分别为21.74%(10/46)、54.76%(23/42)、73.53%(25/34)、82.76%(24/29),3、6、12、18个月MR4.0率分别为6.52%(3/46)、19.05%(8/42)、38.24%(13/34)、48.28%(14/29),3、6、12、18个月MR4.5率分别为0、14.29%(6/42)、35.29%(12/34)、34.48%(10/29),18个月深度分子学反应(DMR)率48.28%(14/29)。所有患者以标准剂量开始治疗,至随访结束,40例(83.33%)患者维持了标准剂量氟马替尼(600 mg/d)。随访时间(20.89±10.98)个月,3年EFS率为78.9%,OS率为94.5%。血液学不良反应依次为血小板减少6例(12.50%),贫血5例(10.42%),白细胞减少4例(8.33%)。非血液学不良反应依次为腹泻8例(16.67%),皮疹 5 例(10.42%),腹胀 4 例(8.33%),肝功能损害 4 例(8.33%),肾功能损害 3 例(6.25%),高胆红素血症 2 例(4.17%)。结论 真实世界中氟马替尼一线治疗老年慢性髓系白血病可提高EMR,预示了DMR及获得无治疗缓解的可能性,且安全性良好。
Abstract:Objective To investigate efficacy and safety of flumatinib as frontline treatment in elderly patients with newly diagnosed chronic myeloid leukemia in real-world,providing a basis for clinical medication. Methods A total of 48 elderly patients with newly diagnosed chronic myeloid leukemia admitted to Affiliated Hospital of Anhui University of Science and Technology from June 2020 to June 2024 were selected as the study subjects,with the age of(72.61±5.03)years. Among them,44 cases(91.67%)had non-hematological comorbidities. All patients received oral flumatinib at a dose of 600 mg once daily. Hematological,cytogenetic and molecular responses(MR),as well as safety indicators,were collected at 3,6,12,and 18 months after treatment. Follow-up was conducted until September 30,2024,and event - free survival(EFS)and overall survival(OS)rates were calculated. Results At 3 months of treatrnent,95.83%(46/48)of patients reached complete hematologic response(CHR)and 100%(43/43)reached CHR at 6 months. The early molecular response(EMR)rates were 82.61%(38/46),92.86%(39/42)and 100%(34/34),respectively at 3,6 and 12 months .The major molecular response(MMR)rates were 21.74%(10/46),54.76%(23/42),73.53%(25/34)and 82.76%(24/29),respectively at 3,6,12,and 18 months. The MR4.0 rates at 3,6,12 and 18 months were 6.52%(3/46),19.05%(8/42),38.24%(13/34)and 48.28%(14/29),respectively. The MR4.5 rates were 0,14.29%(6/42),35.29%(12/34)and 34.48%(10/29)at 3,6,12 and 18 months. The deep MR(DMR)rate was 48.28%(14/29)at 18 months. All patients were started at the standard dose,and by the end of follow - up 40 patients(83.33%)maintained the standard dose flumatinib(600 mg/d). The median follow-up duration was(20.89±10.98)months,with a 3-year EFS rate of 78.9% and an OS rate of 94.5%. Hematological adverse reactions were thrombocytopenia in 6 cases(12.50%),anemia in 5 cases(10.42%)and leukopenia in 4 cases(8.33%). Non-hematologic adversereactions were diarrhea in 8 cases(16.67%),rash in 5 cases(10.42%),abdominal distension in 4 cases(8.33%),liver function damage in 4 cases(8.33%),renal impairment in 3 cases(6.25%),and hyperbilirubinemia in 2 cases(4.17%). Conclusion In the real-world,flumatinib as first-line treatment of elderly CML patients improves EMR,predicting DMR and the possibility of obtaining treatment-free remission,with a good safety profile.
