Abstract

Significance: STC1 is a protein secreted by intratumor endothelial cells in which plasma concentrations increase in patients with chemorefractory mCRC. Based on analyses of patients with refractory mCRC in the TEXCAN and CORRECT trials, we found that STC1 plasma levels had a prognostic role for OS, with high levels associated with poor outcome. A predictive role for baseline STC1 levels was pointed out for regorafenib efficacy.

regorafenib治疗的难治性结直肠癌患者中的Stanniocalcin 1: TEXCAN和CORRECT试验的事后生物标志物分析
化疗难治性转移性结直肠癌(mCRC)缺乏抗血管生成药物的生物标志物。我们在TEXCAN和CORRECT试验中研究了瑞非尼治疗患者的STC1与预后之间的关系。采用ELISA法检测化疗难治性mCRC患者的基线血浆STC1蛋白水平,TEXCAN组(regorafenib组n=48)和CORRECT组(安慰剂组n=211;regorafenib n = 435)。采用Cox比例风险模型评估STC1水平与总生存期(OS)的关系。化疗难治性mCRC患者的STC1中位值(1211 pg/mL)比先前未治疗的患者(215 pg/mL)增加。使用优化的截止值,STC1是OS的预后(HR 2.12, 95% CI 1.79, 2.50;P
