  ASCO 2011报道:Schuetze等的一项研究报告表明,联用西罗莫司(S)和环磷酰胺(C)治疗晚期肉瘤,多数患者耐受良好,1/5的患者肉瘤稳定≥6个月。哺乳动物雷帕霉素靶蛋白(mTOR)活性水平较高的患者较早发生疾病进展。

  该研究在晚期骨肉瘤或软组织肉瘤患者中,进行了一项S(第1天12 mg,随后4 mg/d)与C(隔周每日口服200 mg持续7天)联用的Ⅱ期西蒙最小最大设计(Simon Minimax)临床研究。如出现≥3级毒性反应,减少S和C剂量。持续使用C,直至中性粒细胞<1000/mm3或血小板<75000/mm3。主要目标是估计的6个月PFS率达到≥25%。患者每2个月接受1次影像学随访,以了解其肿瘤应答情况(WHO标准)。治疗4周后检测西罗莫司血清水平,治疗前及4周治疗后检测血脂和血浆血管内皮生长因子(VEGF)水平。使用计量免疫荧光法分析肿瘤组织,获得总体和磷酸化的mTOR和核糖体蛋白S6。使用Log秩检验和考克斯(Cox)回归分析评估生存终点。

  结果显示,研究者在2008年9月~2009年12月共纳入49例符合入选标准的患者(女性21例,男性28例),其中位年龄57岁(19~82 岁),既往接受治疗的中位次数是2次(1~6次)。16例患者为平滑肌肉瘤,9例为脂肪肉瘤,6例为未分化,6例为骨肉瘤,12例为其他亚型肉瘤。中位/ 平均S谷浓度是8.7/9.7 ng/ml(1.3~25.8)。2例患者发生≥3级腹泻、血栓形成、膀胱炎,3例患者发生3级感染,3例死亡,均归因于疾病进展。47例可评估患者中,10例≥6个月疾病无进展,2例完成>12个月治疗。中位PFS为103天,6个月PFS率为21% (SD=0.06%)。中位生存期是328天。甘油三酯基线水平正常和mTOR通路活性水平较低与较长的PFS(P=0.02和P=0.05)和总体生存时间(P=0.06和P=0.03)相关。VEGF血浆水平与转归不相关。
