摘要
为观察干扰素的疗效,应用基因重组α干扰素(IFN-α)治疗48例慢性粒细胞白血病(CML),其中慢性期(CP)45例(2例完全缓解病例),加速期(AP)3例。剂量大多为隔日300万U,4例为每日600万U,平均疗程为8.6个月(3~39个月)。单用IFN-α治疗CMLCP7例,其中3例有效;联用甲异靛治疗17例,联用羟基脲治疗9例,有效率分别为94.1%和55.6%,与单用甲异靛或羟基脲治疗者相比无显著差异;IFN-α同时与甲异靛和羟基脲合用10例,7例有效。IFN-α能明显减少联用药物的剂量,减轻其毒副作用。缓解后12例单用IFN-α维持治疗,平均持续缓解时间为6.5个月。复查Ph+CML29例,治疗后均未达到完全转阴,其中1例Ph染色体阳性率由100%降至8%,9例由100%降至70%~90%,总有效率为34.5%。细胞遗传学好转的患者平均用药剂量和用药时间明显高于细胞遗传学未好转者。结果提示IFN-α可用于CMLCP和缓解后维持治疗,若加大剂量和延长用药时间,有可能进一步提高疗效。IFN-α对CMLAP无效。
