概括
在早期正子发射断层扫描阴性霍奇金淋巴瘤患者中,省略放射治疗增加了复发风险. 对于早期正子发射断层扫描阳性患者,强化化疗并没有显著改善长期无进展生存率,但是安全的.
科学领域:
- 在瘤学瘤学.
- 临床试验 临床试验
- 辐射疗法 辐射疗法
背景情况:
- 临床试验经常在二次分析之前报告主要终点.
- 早期正子发射断层扫描 (ePET) 响应适应的治疗策略正在为霍奇金淋巴瘤发展.
- 之前对H10试验的分析显示,基于ePET状态和治疗修改,结果不同.
研究的目的:
- 报告H10试验对霍奇金淋巴瘤响应适应治疗的最终10年随访结果.
- 评估在EPET阴性患者中省略参与节点放射治疗 (INRT) 的长期疗效和安全性.
- 评估从ABVD切换到BEACOPPesc化疗对ePET阳性患者的长期影响.
主要方法:
- 对H10临床试验进行预先计划的10年随访分析.
- 在EPET阴性和EPET阳性患者组中,治疗手臂之间的10年无进展生存率 (PFS) 的比较.
- 计算了危险比率 (HR) 和P值,以评估治疗差异和非劣质性.
主要成果:
- 在有利的EPET阴性患者中,ABVD + INRT显示显著更高的10年PFS (98.8%),与省略INRT (85.4%) 相比.
- 在不良的EPET阴性患者中,INRT遗漏和纳入之间的10年PFS差异在统计学上并不显著 (91.4%对86.5%).
- 在EPET阳性患者中,标准ABVD和强化BEACOPPesc之间的10年PFS差异在统计学上并不显著 (HR 0.67;P=0.1777).
结论:
- 在EPET阴性霍奇金淋巴瘤患者中省略INRT与较低的10年PFS有关.
- 在ePET阳性患者中加强化学疗法的BEACOPPesc在10年后没有产生统计学上显著的PFS益处.
- BEACOPPesc强化是安全的,没有增加晚期不良事件的发生率,包括第二次恶性瘤.

Treatment Resistant Cancers
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
