概括
这项针对多种质母细胞瘤 (GBM) 的研究发现,在并发化疗放射治疗 (CCRT) 中,顺序增强 (SEB) 和同时整合增强 (SIB) 技术之间的整体存活率没有显著差异. 需要进一步的研究来确定GBM患者的最佳提升策略.
科学领域:
- 神经瘤学神经瘤学
- 辐射瘤学 辐射瘤学
- 临床癌症研究 临床癌症研究
背景情况:
- 多形质母细胞瘤 (GBM) 的标准治疗包括手术,随后是并发化疗放射治疗 (CCRT).
- 在GBM中对CCRT的最佳提升技术仍未确定.
- 目前的CCRT协议通常提供60Gy的总剂量.
研究的目的:
- 为了比较顺序增强 (SEB) 与同时整合增强 (SIB) 在接受CCRT的GBM患者的疗效.
- 评估不同增强技术对整体存活时间 (OS) 的影响.
主要方法:
- 从2016年至2021年期间,对398名用CCRT治疗的GBM患者进行了回顾性审查.
- 患者被分为SEB (N=119) 和SIB (N=279) 组.
- 倾向性得分匹配 (PSM) 用于最大限度地减少群体差异并分析整体存活率.
主要成果:
- 在PSM之前,SEB的运营状况明显好于SIB (2年:55.6%对44.5%,p=0.014).
- 在PSM后,在SEB和SIB组之间没有观察到OS的显著差异 (2年:55.6%与51.5%,p=0.300).
- 增强序列与劣质的OS无关;症状伪进展率在各组之间相似.
结论:
- 在倾向性得分匹配后,在接受CCRT治疗的GBM患者中,在SEB和SIB之间没有发现总生存时间的显著差异.
- 这些发现表明,增强序列可能不会对接受CCRT的GBM患者的结果产生重大影响.
- 需要进一步的研究来证实这些结果,并确定GBM治疗的最佳增强技术.

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...

Cancer Therapies

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...

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
