Anemia is an expected consequence of intensive chemotherapy regimens administered to patients with acute leukemia. This study was designed to determine whether epoetin alpha would decrease the number of transfusion events and units of packed erythrocytes (PRBCs) transfused, and the secondary objective was to study the effects of epoetin alpha on quality of life (QOL) and complete remission (CR) rates.
Patients with acute lymphoblastic leukemia (ALL), lymphoblastic lymphoma (LL), or Burkitt lymphoma (BL) who were receiving frontline myelosuppressive chemotherapy were randomized to receive epoetin alpha or no epoetin during the first 6 cycles of their planned chemotherapy. QOL was assessed by using the Edmonton Symptom Assessment Scale (ESAS) and the Functional Assessment of Cancer Therapy (FACT)-Anemia questionnaires.
Fifty-five patients were randomized to receive epoetin alpha, and 54 patients received no epoetin. Transfusion data were available for 79 of 81 evaluable patients (98%) who completed the treatment/observation period. The trial was stopped early because of poor accrual before the target of 123 evaluable patients was met. A mean of 10.6 units of PRBCs over 5 months were administered to those who received epoetin alpha compared with 13 units for those who did not receive epoetin (P = .04). There was no significant difference in QOL as assessed by the FACT-Anemia or ESAS instruments. The CR rate and the 3-year CR duration were not affected adversely by use of epoetin alpha.
Epoetin alpha decreased the number of PRBC transfusions and did not appear to have a negative impact on remission duration. No difference in QOL was observed.
贫血是接受急性白血病强化化疗方案治疗的患者的预期后果。本研究旨在确定促红细胞生成素α是否会减少输血事件的数量和输血量,次要目的是研究促红细胞生成素α对生活质量(QOL)和完全缓解(CR)率的影响。
接受一线骨髓抑制化疗的急性淋巴细胞白血病(ALL)、淋巴母细胞淋巴瘤(LL)或伯基特淋巴瘤(BL)患者,在计划化疗的前 6 个周期中随机接受促红细胞生成素α或不接受促红细胞生成素α治疗。使用埃德蒙顿症状评估量表(ESAS)和癌症治疗功能评估(FACT)-贫血问卷评估 QOL。
55 例患者随机接受促红细胞生成素α治疗,54 例患者未接受促红细胞生成素α治疗。79 例可评估患者(98%)完成了治疗/观察期,其中 81 例有输血数据。在目标患者数 123 例达到之前,由于入组不佳,该试验提前终止。与未接受促红细胞生成素α治疗的患者相比,接受促红细胞生成素α治疗的患者在 5 个月内平均输注 10.6 单位 PRBC,差异有统计学意义(P =.04)。使用促红细胞生成素α不会对 FACT-贫血或 ESAS 工具评估的 QOL 产生显著影响。CR 率和 3 年 CR 持续时间不受促红细胞生成素α使用的不利影响。
促红细胞生成素α减少了 PRBC 输血的数量,且似乎对缓解持续时间没有负面影响。未观察到 QOL 存在差异。
