概括
尽管PD-L) 1抑制剂是转移性非小细胞肺癌的标准治疗,但现实数据显示,在早期治疗线路中,死亡率和衰竭率很高. 治疗持续时间仍然很短,这表明在管理这种疾病方面存在持续的挑战.
科学领域:
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
- 肺癌研究研究 肺癌研究
背景情况:
- 编程细胞死亡蛋白-1/联结-1 (PD-1/PD-L1) 抑制剂是转移性非小细胞肺癌 (mNSCLC) 的标准治疗方法.
- 对于患有非驱动基因突变mNSCLC的患者,现实世界的治疗模式和结果没有得到很好的描述.
- 了解跨线疗法 (LOT) 的治疗消耗对于改善患者的治疗结果至关重要.
研究的目的:
- 检查非驱动突变mNSCLC的患者中现实世界治疗模式和按治疗线路 (LOTs) 的消耗.
- 通过PD-L1表达水平分层分析PD-L1抑制剂的利用情况.
- 在多种疗法中评估死亡率和治疗持续时间.
主要方法:
- 来自美国多中心数据库的mNSCLC (2015-2022) 成年患者的回顾性研究.
- 对治疗模式,持续时间和结果的分析,包括基于PD-L1表达的PD-L1利用率 (<1%,1%-49%,≥50%).
- 描述性总结1至4个LOT的死亡率和消耗率.
主要成果:
- 基于PD-(L) 1的治疗是最常见的前线治疗 (55.8%),通常与化疗结合使用.
- 前线PD-L1单一治疗最常见于PD-L1表达高的患者 (≥50%).
- 死亡率在1至4的LOT中从37.4%到42.2%不等,每个LOT的消耗率约为60%,LOT1的平均持续时间为5.4个月.
结论:
- 尽管使用PD-L) 1抑制剂,但在mNSCLC的早期疗法中仍然存在高死亡率和衰竭率.
- 短期治疗时间突出了管理mNSCLC的重大挑战.
- 需要进一步的策略来改善mNSCLC患者的长期结果.

Treatment Resistant Cancers
3.7K
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...

Cancer Survival Analysis
630
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...
