概括
老年患者 (≥75岁) 患有无法切除的第三阶段非小细胞肺癌 (NSCLC),在同时接受化疗放射治疗 (cCRT) 和杜尔瓦卢马布治疗后的整体存活期 (OS) 较短. 后进展疗法显示了适度的生存益处,表明需要新的治疗方法.
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:
- 同时进行化疗放射治疗 (cCRT),随后进行杜尔瓦卢马布治疗,对于不可切除的第三阶段非小细胞肺癌 (NSCLC) 是标准的.
- 患者年龄是NSCLC治疗结果和毒性的一个关键因素.
- 了解与年龄相关的生存和治疗反应差异对于优化护理至关重要.
研究的目的:
- 为了评估cCRT加上durvalumab在75岁以下的NSCLC患者的生存结果,与75岁以上的NSCLC患者相比.
- 为了比较进展后的治疗疗效:单独使用免疫检查点抑制剂 (ICI),单独使用化疗,单独使用ICI和化疗.
- 确定影响整体存活 (OS) 和早期停药的因素.
主要方法:
- 对472名患有无法切除的III期NSCLC的患者进行了回顾性分析,这些患者接受了cCRT治疗,随后接受了durvalumab治疗.
- 分析了跨年龄队列的生存结果 (PFS,OS):<65,65-74岁和≥75岁.
- 多变量考克斯回归和后勤回归模型用于识别与OS和治疗中止相关的因素.
主要成果:
- 在75岁以上的患者 (27.6个月) 中,与65岁以下 (60.8个月) 患者相比,中位数的生存寿命显著较短.
- 较老的患者 (≥75) 由于毒性,早期停止杜尔瓦卢马布治疗的几率高出2.2倍.
- 进展后,基于ICI的疗法与单独化疗相比,显示出适度的生存益处.
结论:
- 在接受cCRT加上杜尔瓦卢马布的老年NSCLC患者 (≥75岁) 中,整体存活率显著降低.
- 在这种NSCLC人群中,年龄是生存和治疗毒性的重要预测因素.
- 目前的进展后全身疗法具有有限的疗效,突出显示急需创新的治疗策略.

Treatment Resistant Cancers
3.3K
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 Therapies
7.6K
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Cancer Survival Analysis
328
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...
