概括
在非小细胞肺癌 (NSCLC) 中的主要病理反应 (MPR) 可靠地预测了新辅助疗法后的生存率. 10%的可活性瘤切断率显示出高度的观察者间一致性,并且对腺癌和状细胞癌都是最佳的.
科学领域:
- 在瘤学瘤学.
- 病理学 病理学 病理学
- 手术瘤学手术瘤学
背景情况:
- 主要病理反应 (MPR),定义为≤10%可活性瘤 (VT),是新辅助治疗后非小细胞肺癌 (NSCLC) 的关键预后指标.
- 准确评估MPR对于治疗分层和患者管理至关重要.
研究的目的:
- 评估NSCLC中MPR评估的观察者间可重复性.
- 为了比较余活性瘤 (VT) 百分比的面积加权和未加权计算.
- 确定最佳的VT百分比切断值,以预测不同NSCLC组织学亚型的生存率.
主要方法:
- 在经过新辅助治疗后进行手术切除的108名NSCLC患者的回顾性分析.
- 通过使用数字全幻灯片图像的三名观察员对瘤床和静脉瘤百分比的独立评估.
- 统计分析包括Dice系数,交叉对联,类内相关系数和Fleiss' kappa以评估可重复性和一致性.
主要成果:
- 瘤床划分的总体一致性高 (Dice=0.96,IoU=0.92),在较小的平细胞癌 (SqCC) 瘤床中可复制性降低.
- 对于VT百分比 (ICC=0.959) 和MPR使用10%的切割率 (Fleiss' kappa=0.911) 的优秀协议.
- 在面积加权和未加权VT计算之间,MPR状态的最小差异.
- 10%的VT截止值对于腺癌 (ADC) 和SqCC.都是最佳的.
- 与MPR患者相比,MPR+患者 (17%) 的无事件生存率 (p=0.015) 和整体生存率 (p=0.023) 较好.
- 与ADC相比,SqCC显示出更高的MPR+率,较低的VT%,以及更好的无事件生存率.
结论:
- 瘤床大小变化的影响最小,MPR评估显示了强大的观察者间可重复性.
- 10%的可活性瘤切断值是NSCLC在不同组织学亚型中生存的可靠预测指标.
- 在SqCC中仔细评估较小的瘤病床是有必要的,但10%的切断率仍然有效用于生存预测.

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...

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.
