目的:一个三臂随机III期临床试验中晚期大肠癌患者的目的是要测试是否为(1)L-甲酰四氢叶酸或(2)亚叶酸钙口服同等剂量的替代会更有效地使可能氟尿嘧啶(5-FU)比标准静脉注射(IV)(D,L) - 亚叶酸钙。 患者和方法:一共有926化疗天真患者参加。患者接受三种治疗方法之一:(一)强化道5-FU加左旋亚叶酸钙与四亚叶酸钙(Immunex的公司,西雅图,华盛顿州),100 mg/m2及静脉5-FU 370 mg/m2,(B)密集道5-FU加口服(D,L) - 亚叶酸钙口服leucovarin在125 mg/m2,第小时0,1,2,和3(总剂量500 mg/m2),接着用5-FU 370毫克/ M2在4小时或(c)密集道5-FU加四(D,L),亚叶酸钙与四亚叶酸钙200 mg/m2和5-FU 370 mg/m2。药物,每日连续5天给药。课程重复,在4周和8周,此后每5个星期。剂量减少为中性粒细胞减少,血小板减少,腹泻,口腔炎,皮炎。 结果:926符合条件的患者中,有756人死亡。整体回应率例可评价患者为32%(514 165)。有响应速率方案之间无显着差异(A组,28%[140 47] B组,34%[60 174];和ARM C,34%[170 58]),或在生存。已经有九个可能的化疗相关死亡。III级至IV毒性作用并不明显由ARM不同,包括口腔炎(12%〜14%),腹泻(15%至19%),恶心(7%〜9%),呕吐(6%〜8%) 。 结论:在这三个不同的亚叶酸钙制剂联合5-FU之间的反应,生存期,或毒性没有什么区别。
