概括
这项研究表明,对结节阳性宫癌的同时综合增强放射治疗提供了高响应率和良好的盆腔控制,具有低毒性. 然而,远程复发仍然是令人担忧的,特别是对前大动脉节点的参与.
科学领域:
- 在瘤学瘤学.
- 辐射瘤学 辐射瘤学
- 妇科瘤学 妇科瘤学
背景情况:
- 在宫癌的节点参与显著恶化预后.
- 现代放射治疗技术,如强度调节放射疗法 (IMRT) 和体积调节弧线疗法 (VMAT),可以安全地将剂量升级到淋巴结.
- 印度人群和节点阳性亚组中剂量升级节点放射治疗的临床数据有限.
研究的目的:
- 评估同步综合增强 (SIB) 放射治疗对节点阳性,局部晚期宫癌患者的放射性参与节点的结果和毒性.
- 评估剂量升级结节放射治疗在实现瘤和结节反应方面的疗效.
- 分析存活率和失败模式,特别是与准大动脉结节疾病相关.
主要方法:
- 对56名患有节点阳性,局部晚期子宫癌的患者的回顾性分析,这些患者在2018年至2023年期间接受治疗.
- 所有患者都接受了盆腔外部光束放射治疗,同时对受影响的节点进行综合增强 (SIB),然后进行内支臂疗法.
- 在可行的情况下,每周给予西斯普拉丁化疗;评估瘤/节点反应和生存率.
主要成果:
- 完整应答率很高:初级瘤为81.8%,结节疾病为91%.
- 五年地方和区域控制率分别为86%和85%. 远程无复发生存率为64%,整体生存率为68%.
- 与IIIC1 (p=0.047) 相比,患有准大动脉结节疾病 (IIIC2) 的患者远程控制较差. 晚级≥3GI/GU毒性低 (3.6%/1.8%),但阴道狭窄发生在25%.
结论:
- 用IMRT/VMAT和SIB对节点进行终极化疗,可以实现高响应率,优秀的骨盆控制,并在节点阳性宫癌中具有低严重晚期毒性.
- 远程复发是主要的失败模式,特别是在患有偏大动脉节点参与的患者中,这表明需要系统性治疗加剧.
- 节点剂量升级是一种安全而实用的策略,支持其使用,同时强调对高风险患者需要新的全身疗法.

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
645
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...
