概括
结合炎症,营养和肉症的新模型预测了在全新辅助疗法 (TNT) 后,局部晚期直肠癌 (LARC) 患者的病理反应. 这些人工智能和复合分数有助于做出治疗决策,以保护器官和手术时间.
科学领域:
- 在瘤学瘤学.
- 结直肠癌研究 结直肠癌研究
- 预测模型在医学中的预测模型.
背景情况:
- 总的新辅助疗法 (TNT) 是局部晚期直肠癌 (LARC) 的标准,但病理完整反应 (pCR) 率有所不同.
- 系统性炎症,营养状况和肉是已知的预后因素,但整合预测模型缺乏.
- 预测治疗反应对于优化LARC管理和患者结果至关重要.
研究的目的:
- 开发和验证基于临床,实验室和人工智能的模型,用于预测接受TNT的LARC患者的病理反应.
- 评估炎症标志物 (CAR,SII),肉症和临床因素的预测价值.
- 为风险分层建立复合分数 (CINR) 和机器学习模型.
主要方法:
- 对93名LARC患者的回顾性分析,他们接受了TNT治疗,随后进行了手术.
- 通过CT评估肉类,并使用C反应蛋白/白蛋白比率 (CAR) 和全身免疫炎症指数 (SII) 评估炎症/营养状况.
- 开发复合CINR得分和随机森林 (RF) 模型来预测pCR和良好的病理反应 (TRG 0-1).
主要成果:
- 病理完整响应 (pCR) 在21.5%的患者中实现,良好的病理响应 (TRG 0-1) 在46.2%的患者中实现.
- 对于pCR的预测因素包括没有TNT后的肉症,低CAR,低SII,低LDH和甲胺使用.
- CINR评分 (AUC 0.846-0.868) 和射频模型 (AUC 0.910-0.933) 显示出强大的病理反应预测性能.
结论:
- 综合的炎症,营养和肉症标志物,以及CINR得分和AI模型,可以准确预测LARC中的病理反应.

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Cancer Survival Analysis
634
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...

Tumor Progression
7.2K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
