概括
一个新的综合模型准确地预测了片切除后结直肠癌 (CRC) 风险,包括患者的因素,如年龄和糖尿病,以及片特征. 这改进了目前的指导方针,这些指导方针仅依赖于多发现的风险分层.
科学领域:
- 胃肠道学和瘤学
- 医学中的预测分析.
背景情况:
- 目前的结肠直肠癌 (CRC) 监测指南依赖于聚的特征来进行风险分层,这种分层往往不准确.
- 整合额外的患者风险因素可能会提高术后风险评估的准确性.
研究的目的:
- 为了比较一个综合风险模型的预测性能与一个仅为多胞体的模型用于多胞体切除术后的CRC.
- 评估患者人口统计和临床病史在细化腺瘤切除后CRC风险预测中的有用性.
主要方法:
- 考克斯回归模型是使用95,001名患者的数据开发的,这些患者接受了基线结肠镜检查和腺瘤切除 (2004-2016).
- 综合模型包括年龄,糖尿病,结肠镜指示,和多发现 (组织学,大小).
- 仅使用多模型进行比较,通过AUC和校准评估性能.
主要成果:
- 综合模型在发育 (AUC 0.71) 和验证 (AUC 0.70) 队列中表现出优异的预测性能,与单纯的多模型 (AUC 分别为0.61和0.62) 相比.
- 这两种模型都显示了适当的校准,表明了可靠的风险估计.
- 综合模型显示,在预测多叶瘤术后的CRC诊断方面有显著的改善.
结论:
- 综合性CRC风险预测模型包括患者年龄,糖尿病和结肠镜指示,除了多发现外,比仅基于多特征的模型更准确.
- 这种增强的模型提供了更好的风险分层对结肠镜多片移除后的患者,可能优化监测策略.

01:21Cancer Survival Analysis

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...

6.2K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.
