第六届世界肺高血压会议对肺高血压(pulmonary hypertension,PH)的定义和诊断分类进行了修订和更新。PH的血流动力学定义维持不变,将毛细血管前性PH定义更新为:肺动脉平均压〉20 mm Hg、肺动脉楔压〈15 mm Hg且肺血管阻力〉3 WU。诊...第六届世界肺高血压会议对肺高血压(pulmonary hypertension,PH)的定义和诊断分类进行了修订和更新。PH的血流动力学定义维持不变,将毛细血管前性PH定义更新为:肺动脉平均压〉20 mm Hg、肺动脉楔压〈15 mm Hg且肺血管阻力〉3 WU。诊断分类更新包括:增加急性肺血管扩张试验阳性肺动脉高压(pulmonary arterial hypertension,PAH)亚类,将甲基苯丙胺(冰毒)和达沙替尼致PAH作用由可能升级为肯定,将肺静脉闭塞病/肺毛细血管瘤病由特殊的1'更新为PAH的一个亚类,将脾切除术后和甲状腺疾病从PH诊断分类中移除等。本次PH定义和诊断分类更新将为临床实践提供重要指导意义。展开更多

方法回顾性分析2014年1月至2017年6月期间就诊并行造血干细胞移植的63例Ph+ALL患者的临床特征及转归,比较一线应用国产达沙替尼与伊马替尼的疗效。
结果应用国产达沙替尼者31例,应用伊马替尼者32例。两组患者诱导治疗4周完全缓解(CR)率分别为96.8%和93.8%(P=1.000),诱导治疗4周主要分子学反应(MMR,BCR-ABL拷贝数较基线下降3个对数级)率分别为41.9%和43.8%(χ2=0.021,P=0.884),移植前复发率分别为6.5%和12.5%(P=0.672),移植前MMR率分别为83.9%和68.8%(χ2=1.985,P=0.159),差异均无统计学意义。国产达沙替尼组和伊马替尼组20个月总生存(OS)率分别为95.5%、76.5%,20个月无事件生存(EFS)率分别为93.5%、61.4%,两组OS时间差异无统计学意义(χ2=0.990,P=0.320),EFS时间差异有统计学意义(χ2=5.926,P=0.015)。多因素分析显示应用国产达沙替尼(HR=0.201,95% CI 0.045~0.896,P=0.035)和移植前获得MMR(HR=0.344,95% CI 0.124~0.956,P=0.041)的患者具有更好的EFS。
结论TKI联合化疗并序贯造血干细胞移植治疗Ph+ALL时,与一线应用伊马替尼相比,一线应用国产达沙替尼者EFS更优。展开更多

The results showed that there were no significant differences in the rates of optimal response between Yinishu and SPRYCEL for patients who started second-line treatment because of treatment failure.For patients who started second-line treatment because of intolerance of first-line treatment, their levels of BCR-ABL1/ABL1 on the international scale (BCR-ABL^IS)was maintained very low throughout the course of Yinishu treatment.Drug-related adverse events occurred with the same frequency in these two groups.It was confirmed that Yinishu was effective and safe as a second- line treatment for CML patients.Yinishu may be more suitable for patients who are economically unable to pay for the patented dasatinib SPRYCEL.展开更多
