概括
高O-GlcNAc表达预测非小细胞肺癌 (NSCLC) 患者的放射治疗反应和生存率更好. 低O-GlcNAc水平与较差的结果有关,与葡萄糖代谢指标不同.
科学领域:
- 在瘤学瘤学.
- 生物化学 生物化学
- 分子生物学分子生物学
背景情况:
- 关于蛋白质糖化,特别是O-GlcNAcylation (O-GlcNAc),在预测非小细胞肺癌 (NSCLC) 放射治疗 (RT) 反应方面存在有限的证据.
- 这项研究研究了O-GlcNAc表达和葡萄糖代谢指标在RT反应和NSCLC患者的预后中的作用.
研究的目的:
- 调查O-GlcNAc表达与NSCLC中的RT反应之间的关联.
- 评估O-GlcNAc表达对NSCLC患者无进展生存期 (PFS) 和整体生存期 (OS) 的预后影响.
- 为了将O-GlcNAc的预测值与葡萄糖代谢指标 (血糖和SUVmax) 进行RT反应和预后的比较.
主要方法:
- 对216名接受RT和PET-CT治疗的NSCLC患者进行了回顾性队列研究.
- 免疫组织化学 (IHC) 评估了治疗前瘤样本中的O-GlcNAc表达.
- 多变量和有条件的逻辑回归分析了关联;卡普兰-梅尔评估了生存结果.
主要成果:
- 低O-GlcNAc表达独立地与较差的RT反应 (OR=2.47) 相关,并预测了较短的PFS (P=0.049) 和OS (P=0.008).
- 血糖和原发性瘤SUVmax与RT反应或PFS没有关联.
- 高SUVmax预测较短的OS (P=0.03),但O-GlcNAc是RT反应和生存的更强的预测因素.
结论:
- 高O-GlcNAc表达是NSCLC患者有利的RT反应的重要预测因素.
- 在接受RT的NSCLC患者中,O-GlcNAc表达是改善PFS和OS的有价值的预后生物标志物.
- 在NSCLC中,O-GlcNAc表达是RT反应和预后的更可靠指标,而不是NSCLC中的葡萄糖代谢指标.

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.

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...
