概括
手术后肺癌复发是很常见的. 淋巴血管侵袭和PET扫描SUVmax等因素可以预测TNM分期之外的复发,有助于治疗决策.
科学领域:
- 在瘤学瘤学.
- 胸部外科手术 胸部外科手术
- 医疗成像医学成像
背景情况:
- 治疗性手术后肺癌复发是一个重大的临床挑战.
- 目前的预后严重依赖于瘤,结节,转移 (TNM) 的分期.
- 确定额外的风险因素对于优化外科手术期间治疗选择至关重要.
研究的目的:
- 为了确定非小细胞肺癌 (NSCLC) 复发的危险因素,超出TNM分期.
- 调查肺癌复发后与整体生存相关的因素.
- 为了提高治疗意图的肺癌手术患者的预后准确度.
主要方法:
- 对NSCLC患者机构数据库 (2004-2014) 的回顾性分析.
- 患者特征,诊断和手术程序的比较,使用基平方和ANOVA测试.
- 多变量Cox比例危险模型和Kaplan-Meier分析来评估复发和生存预测指标.
主要成果:
- 在1195名NSCLC患者中,33%的患者出现了复发;5年生存率为72.2%没有复发,而复发的患者为47.4%.
- 复发的危险因素包括切除,淋巴血管侵袭 (LVI),内脏膜侵袭 (VPI) 和更高的手术前PETSUVmax.
- 最少侵入性手术改善了复发病例的生存率,而状组织学和某些切除 (双骨切除术,袖叶切除术) 恶化了生存率.
结论:
- 三分之一的NSCLC患者在手术后复发,影响长期生存.
- 切除,LVI,VPI和SUVmax是复发的重要预测因素,增加了TNM阶段.
- 这些因素可以改进新疗法和临床试验的预后和患者选择.

Cancer Survival Analysis
629
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 Stem Cells and Tumor Maintenance
5.8K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...
