概括
基于阿斯巴拉金酶的化疗改善了晚期或复发/耐药的外节NK/T细胞淋巴瘤 (ENKTCL) 的存活率. 爱斯坦-巴尔病毒 (EBV) DNA阳性表明结果不佳,需要新的策略来抑制EBV病毒性.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 免疫学 免疫学 免疫学
背景情况:
- 外节NK/T细胞淋巴瘤 (ENKTCL) 具有破坏性的局部影响和全身细胞因子诱导.
- 虽然局部性ENKTCL显示辐射和非环素化疗的生存率有所改善,但晚期或复发/耐药 (R/R) 病例的结果有所变化.
研究的目的:
- 进行元分析,评估高级或R/R ENKTCL的预后因素.
- 评估阿斯巴拉金酶基化疗对ENKTCL生存结果的影响.
主要方法:
- 使用随机效应模型进行了元分析.
- 由于有限的前性试验,使用数字提取器分析了卡普兰-梅尔图.
主要成果:
- 在先进的ENKTCL中,阿斯巴拉金酶治疗的中位数无进展生存期 (PFS) 为14.3个月,总生存期 (OS) 为19个月.
- 在R/R ENKTCL中,PFS为11.7个月,OS为15.6个月.
- 阿斯帕拉金酶,特别是PEG-阿斯帕拉金酶,在先进的ENKTCL中改善了OS. 治疗前爱斯坦-巴尔病毒 (EBV) -DNA阳性与高级和R/R ENKTCL的不良结果相关.
结论:
- 使用拉斯帕拉金酶或PEG-asparaginase的化疗可以提高晚期或R/R ENKTCL的存活率.
- 未来的战略应侧重于抑制EBV病毒性病,并实现深度瘤反应,以更好地根除.

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...
