研究目的: |
①本研究拟探索RAS抑制剂氯沙坦联合贝伐珠单抗治疗mCRC患者的临床效果及安全性。为后续的扩大样本的临床研究做前期准备。 ②通过本研究,要明确:a. mCRC患者的肿瘤组织中CAFs标志物(α-SMA、vimentin、FAP和PDGFR-α、LOXL2)、血管生成(VEGFR、CD31、PAS)、ECM硬度(I、III、IV型胶原蛋白)等是否存在差异表达;b. RAS抑制剂对贝伐珠单抗治疗的疗效如PFS、OS、DCR、ORR是否有影响;c. ECM硬度与抗血管生成治疗疗效是否有相关性。 ③从细胞外基质(ECM)角度寻找调控抗血管生成治疗抵抗的新方法,从而增加抗血管生成治疗的敏感性和疗效。 |

Objectives of Study: |
① This study aims to explore the clinical efficacy and safety of RAS inhibitor losartan combined with bevacizumab in the treatment of mCRC patients. To make preliminary preparation for the subsequent clinical study with enlarged samples. ② Through this study, it was necessary to clarify: a. Whether CAFs markers (α-SMA, vimentin, FAP and PDGFR-α, LOXL2), angiogenesis (VEGFR, CD31, PAS), ECM hardness (type I, III, IV collagen), etc., were differentially expressed in tumor tissues of mCRC patients; b. Whether RAS inhibitors have an effect on the therapeutic efficacy of bevacizumab, such as PFS, OS, DCR and ORR; c. Whether ECM hardness is correlated with the efficacy of anti-angiogenic therapy. ③ From the perspective of extracellular matrix (ECM) to find a new method to regulate the resistance of anti-angiogenic therapy, so as to increase the sensitivity and efficacy of anti-angiogenic therapy. |
