概括
杜尔瓦卢马布在化学辐射疗法 (CRT) 后的EGFR突变患者的不可切除的第三期非小细胞肺癌 (NSCLC) 患者中是安全有效的. 这种治疗序列显示了这个患者群的有希望的结果.
科学领域:
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
- 胸部癌症 胸部癌症 乳腺癌
背景情况:
- 无法切除的第三期非小细胞肺癌 (NSCLC) 需要有效的治疗策略.
- 杜尔瓦卢马布在患有表皮生长因子受体 (EGFR) 突变后化学放射治疗 (CRT) 的NSCLC患者中的作用尚不清楚.
- 确定最佳治疗序列对于改善患者的治疗结果至关重要.
研究的目的:
- 评估杜尔瓦卢马布在患有无法切除的第三阶段NSCLC和EGFR突变的患者中进行CRT的安全性和疗效.
- 为了比较EGFR突变和EGFR野生型NSCLC患者的结局,这些患者在CRT后接受了杜尔瓦卢马布治疗.
- 评估杜尔瓦卢马布的安全性,包括不良事件和停止治疗.
主要方法:
- 在2018年6月至2021年3月期间,对673名无法切除的III期NSCLC患者进行了回顾性多中心研究,这些患者接受了CRT治疗.
- 评估EGFR突变状态;患者被分为EGFR阳性 (n=51) 和EGFR阴性 (n=311) 组.
- 分析了杜尔瓦卢马布的疗效 (无进展生存) 和安全性 (不良事件).
主要成果:
- 平均无进展生存时间为EGFR阳性患者的23.0个月,EGFR阴性患者的24.2个月 (HR 1.03).
- 肺炎是最常见的不良事件 (62.2%的EGFR阳性,62.3%的EGFR阴性),3级的发病率很低.
- 没有观察到与治疗相关的死亡;31.1%的EGFR阳性患者接受了随后的向治疗.
结论:
- 在CRT后的杜尔瓦卢马布似乎是患有无法切除的EGFR突变的III期NSCLC患者的潜在安全和有效的治疗选择.
- 安全性和有效性概况与EGFR阴性对应物相似.
- 这种治疗序列需要进一步研究,作为EGFR突变NSCLC的可行策略.

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...
