Anaemia commonly occurs in cancer patients receiving chemotherapy, often necessitating blood transfusion. This multicentre study was designed to evaluate the efficacy and safety of epoetin alpha in preventing the decline in haemoglobin (Hb) level, and to determine whether the transfusion requirement could be reduced, in patients receiving 4-6 cycles of primarily platinum-based combination cyclic chemotherapy for small cell lung cancer (SCLC). A total of 130 non-anaemic SCLC patients were randomized to receive no additional treatment (n = 44), epoetin alpha 150 IU kg(-1) subcutaneously (s.c.) three times a week (n = 42) or 300 IU kg(-1) s.c. three times a week (n = 44). Reductions in epoetin alpha dosage were made during the study if Hb level increased to >15 g dl(-1). The mean weekly dosage was 335 and 612 IU kg(-1), respectively, in the two active treatment groups. Significantly fewer (P < 0.05) epoetin alpha-treated patients experienced anaemia (Hb < 10 g dl(-1)) during the course of chemotherapy (300 IU kg(-1), 39%; 150 IU kg(-1), 48%; untreated, 66%). This was reflected in the significantly lower number of treated patients transfused [300 IU kg(-1), 20% (P< 0.001); 150 IU kg(-1), 45% (P< 0.05); untreated, 59%]. Epoetin alpha was well-tolerated, and there was no evidence of sustained, clinically significant, hypertension. In summary, epoetin alpha is effective and well-tolerated in maintaining Hb level and reducing transfusion requirement in patients undergoing cyclic chemotherapy for SCLC.
贫血在接受化疗的癌症患者中很常见,常常需要输血。这项多中心研究旨在评估促红细胞生成素α预防血红蛋白(Hb)水平下降的疗效和安全性,并确定在接受4 - 6周期以铂类为主的联合循环化疗的小细胞肺癌(SCLC)患者中是否可以减少输血需求。总共130例非贫血的SCLC患者被随机分为三组,分别接受不额外治疗(n = 44)、促红细胞生成素α 150 IU kg⁻¹皮下注射(s.c.)每周三次(n = 42)或300 IU kg⁻¹ s.c.每周三次(n = 44)。如果Hb水平升至>15 g dl⁻¹,则在研究期间减少促红细胞生成素α的剂量。两个活性治疗组的平均每周剂量分别为335和612 IU kg⁻¹。在化疗过程中,接受促红细胞生成素α治疗的患者发生贫血(Hb < 10 g dl⁻¹)的人数明显较少(P < 0.05)[300 IU kg⁻¹组为39%;150 IU kg⁻¹组为48%;未治疗组为66%]。这反映在接受输血的治疗患者数量显著减少上[300 IU kg⁻¹组为20%(P < 0.001);150 IU kg⁻¹组为45%(P < 0.05);未治疗组为59%]。促红细胞生成素α耐受性良好,没有证据表明存在持续的、具有临床意义的高血压。总之,促红细胞生成素α在维持接受SCLC循环化疗患者的Hb水平和减少输血需求方面是有效且耐受性良好的。
