概括
服用口服泰加-乌拉 (UFT) 的维持化疗并没有改善局部晚期宫癌 (LACC) 患者在同时接受化疗放射治疗 (CCRT) 后的无进展生存率或整体生存率. 应该探索细胞毒性化疗之外的替代策略,以提高结果.
科学领域:
- 妇科瘤学 妇科瘤学
- 医学瘤学 医学瘤学
- 临床试验 临床试验
背景情况:
- 同时化疗放射治疗 (CCRT) 是局部晚期宫癌 (LACC) 的标准.
- 高复发率需要改进治疗策略.
- 目前正在研究维持化疗以提高CCRT的疗效.
研究的目的:
- 评估口服泰加-乌拉 (UFT) 作为LACC中CCRT后的维持化疗的疗效.
- 为了比较UFT维护和观察组之间的无进展生存 (PFS) 和整体生存 (OS).
- 评估UFT维持治疗的安全性和耐受性.
主要方法:
- 一个多中心的第三阶段随机试验 (GOTIC-002) 招募了351名LACC患者 (阶段Ib2-IVa).
- 在CCRT后实现缓解的患者被随机分配到观察或UFT维护 (300-400 mg/天2年).
- 主要终点是PFS;次要终点包括OS和安全性.
主要成果:
- 在观察 (61.3%) 和UFT (62.0%) 组之间,中位数PFS或5年PFS率没有显著差异.
- 五年后的OS率也是可比的 (77.6%对76.1%).
- 维护UFT显示了较高的不良事件率 (93.5%vs73.9%),尽管大多是轻度/中度,但没有改善生存结果.
结论:
- 低剂量口服UFT维护化疗在CCRT后的LACC患者中没有改善PFS或OS.
- 研究结果表明,需要重新考虑维持治疗策略.
- 未来的研究应该探索替代的,非细胞毒的方法来提高LACC的存活率.

Tumor Immunotherapy
462
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

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.
