概括
患有食道状细胞癌 (ESCC) 的患者在新辅助化疗放射治疗 (NCRT) 后获得完整反应 (ypT0) 仍然存在结节转移的风险. 病理N分类独立预测这些ypT0ESCC患者的生存结果.
科学领域:
- 在瘤学瘤学.
- 胃肠病学 胃肠病学
- 胸部外科手术 胸部外科手术
背景情况:
- 新辅助化学放射治疗 (NCRT) 是食道状细胞癌 (ESCC) 的标准治疗方法.
- 病理完整反应 (pCR),定义为ypT0,表明初级瘤的成功治疗.
- 然而,对于ypT0ESCC患者的瘤结果,特别是关于残留结节疾病的结果,需要进一步调查.
研究的目的:
- 为了研究患有食道状细胞癌 (ESCC) 患者的瘤结果.
- 分析那些在新辅助化学放射治疗 (NCRT) 后实现了原发性瘤 (ypT0) 病理完整反应 (pCR) 的患者.
- 为了确定ypT0ESCC患者的生存预测因素.
主要方法:
- 胸部ESCC患者接受NCRT治疗后进行手术的回顾性分析 (2010年1月至2022年12月).
- 纳入标准:ypT0疾病 (没有残留的原发性瘤).
- 评估总生存率 (OS) 和无疾病生存率 (DFS) 和预后因素.
主要成果:
- 分析了118名患有ypT0ESCC的患者;92人实现了ypT0N0,26人患有ypT0N+疾病.
- 剩余结节转移 (ypT0N+) 主要发生在腹部淋巴结 (45/52) 中,并且更频繁地发生在第三下食道瘤中.
- 五年后的OS和DFS率分别为77.1%和69.0%. 病理学N分类是OS和DFS的独立预测因素.
结论:
- 剩余结节转移性疾病是ypT0ESCC患者在NCRT后的一个问题,通常位于腹部淋巴结.
- 病理N分类是这一患者群体的总生存率和无疾病生存率的关键独立预测指标.
- 需要进一步研究 ypT0 ESCC 患者的节点状况管理.

Cancer Survival Analysis
334
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

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...
