概括
编程死亡连接体1 (PD-L1) 和乳腺癌基因1-关联蛋白 (BAP-1) 表达与肺部间皮瘤患者的生存率较差相关. 整合素相关激酶 (ILK) 没有预后价值,突出了PD-L1和BAP-1作为潜在的生物标志物.
科学领域:
- 在瘤学瘤学.
- 生物标志物研究 生物标志物研究
- 癌症预后 癌症预后
背景情况:
- 腹半径质瘤 (PM) 是一种罕见的癌症,预后不佳.
- 识别预后和预测生物标志物对于改善PM治疗策略至关重要.
- 之前对PD-L1,ILK和BAP-1作为PM中的生物标志物的研究已经产生了有限和相互矛盾的结果.
研究的目的:
- 研究PM患者中PD-L1,ILK和BAP-1的表达模式.
- 评估PD-L1,ILK和BAP-1在预测PM患者预后方面的预后作用.
主要方法:
- 对52名连续的PM患者的单中心队列的回顾性分析.
- 评估PD-L1表达 (TPS和CPS),BAP-1损失和ILK表达水平.
- 统计分析以将生物标志物表达与瘤阶段,亚型和整体存活率 (OS) 相关联.
主要成果:
- 在52% (TPS ≥1%) 和65% (CPS ≥1) 的患者中观察到PD-L1表达,在69%的患者中观察到BAP-1损失,在80%的患者中观察到高ILK表达 (≥50%).
- 阳性PD-L1表达在非表皮状亚型中更频繁 (p=0.045),PD-L1和ILK强度与晚期瘤阶段相关 (p=0.034,p=0.032).
- 与阴性/野生型病例 (20.0个月) 相比,PD-L1 (TPS≥1%) 和BAP-1阳性与数量上较差的生存期 (分别为15.3个月和11.3个月) 相联系. PD-L1 CPS ≥1%与BAP-1阳性或高ILK表达的组合也预测了更差的生存率 (p=0.045,p=0.019).
结论:
- 在PM患者中,PD-L1和BAP-1表达与更糟糕的生存结果有关.
- 在这个队列中,ILK表达没有显示出预后价值.
- 需要进行更大规模的研究来验证这些发现,并确定PD-L1和BAP-1是个性化PM治疗的可靠预后和预测生物标志物.

Abnormal Proliferation
4.4K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
