概括
新辅助化疗免疫疗法 (nCIT) 在宫淋巴结转移的食道状细胞癌 (ESCC) 中显示出高病态完整反应率. 这种方法可以提高外科手术的资格,并为高级ESCC提供有希望的1年无病生存期.
科学领域:
- 在瘤学瘤学.
- 手术瘤学手术瘤学
- 医学瘤学 医学瘤学
背景情况:
- 带有非区域性宫淋巴结转移 (CLNM) 的食道状细胞癌 (ESCC) 存在治疗挑战.
- 对于这种特定的ESCC呈现缺乏确定的治疗指南和结果.
- 包括免疫疗法,化疗和手术在内的多式疗法对非区域性CLNM在ESCC中的疗效尚不清楚.
研究的目的:
- 评估新辅助化疗免疫疗法 (nCIT) 的安全性和有效性,然后在患有ESCC和非区域性CLNM的患者中进行手术.
- 评估宫淋巴结的病理反应和整体生存结果.
- 确定nCIT是否可以重新定义最初无法手术的转移性疾病患者的手术资格.
主要方法:
- 对15名患有胸部ESCC和非区域CLNM的患者进行了回顾性队列研究.
- 患者接受了nCIT,随后是McKeown食道切除术与三场淋巴切除术.
- 分析了病理反应,安全性 (术后并发症,与治疗相关的不良事件) 和生存率 (无疾病生存率).
主要成果:
- 93.3%的患者在宫淋巴结转移中获得了病理完整反应 (pCR).
- 总体的pCR率 (ypT0N0M0) 为33.3%.
- 在18.0个月的中位数随访后,1年无病生存率 (DFS) 为91.7%,治疗相关的不良事件可控.
结论:
- 新辅助化疗免疫疗法 (nCIT) 在非区域转移的ESCC患者的宫淋巴结中显示出显著的病理反应.
- 这种多模式的方法显示出扩大晚期疾病患者的手术候选人潜力.
- 有前途的1年期DFS需要在前性研究中进行进一步的调查,以验证长期结果.

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.

Tumor Immunotherapy
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.
