概括
瘤坏死百分比是骨髓瘤预后的关键. 90%的切断率有利于骨质芽细胞瘤,但不管死亡程度如何,质芽细胞亚型的存活率相似.
科学领域:
- 整形瘤学 整形瘤学
- 手术病理学手术病理学
- 癌症预后 癌症预后
背景情况:
- 瘤坏死百分比是骨髓瘤的关键预后指标.
- 目前90%的缩切线主要是基于骨质细胞亚型,可能不适用于所有常规骨质肉瘤类型,包括骨质细胞亚型.
- 调查瘤亡的亚型特定预后值是必不可少的.
研究的目的:
- 评估瘤缩≥90%是否与改善的整体存活率 (OS) 和 osteoblastic 和 chondroblastic骨髓瘤的无病存活率 (DFS) 相相关.
- 为了确定骨髓瘤亚型是否影响瘤缩.
- 评估骨髓瘤亚型是否影响≥90%瘤缩的患者的OS和DFS.
主要方法:
- 对156名患有骨质可塑性骨质肉瘤和骨质可塑性骨质肉瘤的患者的回顾性分析.
- 他们接受了标准化疗和R0切除手术.
- 使用了倾向性得分匹配,卡普兰-梅尔生存分析和考克斯比例危险建模.
主要成果:
- 骨质细胞骨髓瘤与≥90%的亡显著改善了5年和10年的OS和DFS.
- 冠状细胞骨髓瘤呈现出非显著的改善OS和DFS的趋势,死亡缩≥90%.
- 骨髓瘤亚型对实现<90%或<70%瘤缩的可能性没有影响.
- 在这两种亚型中,良好反应者 (≥90%的亡) 具有可比的OS和DFS.
结论:
- 骨髓瘤亚型不是化学疗法反应不佳的预测因素.
- 骨质母细胞和骨质母细胞骨髓瘤亚型在获得良好的反应 (≥90%的瘤缩) 时表现出类似的生存结果.

Tumor Progression
6.2K
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...

Cancer Survival Analysis
328
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...
