概括
脊髓转移性前列腺癌 (PCSM) 的存活率受到PTEN突变和吸烟状态的影响,这些都与总体存活率 (OS) 的降低有关. 前列腺的放射治疗改善了OS,而化疗恶化了神经系统的结果.
科学领域:
- 在瘤学瘤学.
- 神经外科 神经外科
- 遗传学 是一个遗传学.
背景情况:
- 脊髓转移性前列腺癌 (PCSM) 呈现出显著的发病率和死亡率.
- 在PCSM中生物标志物的预测影响仍然不太清楚.
研究的目的:
- 研究PCSM患者的生物标志物,治疗方法和结果之间的关联.
- 确定影响PCSM生存和神经功能的预后因素.
主要方法:
- 68名PCSM患者 (2013-2023) 的回顾性分析.
- 评估生物标志物,治疗方式,人口统计,整体存活率 (OS),转移后存活率,复发和神经结果 (弗兰克尔分数).
- 使用了加速失效时间 (AFT) 模型,卡普兰-梅尔分析和费舍尔的精确测试.
主要成果:
- PTEN突变和吸烟与下降的OS有关. 前列腺的放射治疗改善了OS.
- PTEN和TP53突变与脊髓转移复发的增加相关.
- 化疗对术后神经功能产生了负面影响 (弗兰克尔评分).
结论:
- PTEN突变和吸烟状态是PCSM中OS的负预后指标.
- PTEN和TP53突变与更高的脊髓转移复发率有关.
- 前列腺放射治疗延长了生存期;脊柱放射治疗没有. 化疗会影响神经系统的恢复.

Tumor Progression
6.5K
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...

mTOR Signaling and Cancer Progression
3.9K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
