Effect of neoadjuvant chemotherapy on malignant molecule levels in tumor tissue and serum of patients with locally advanced resectable colorectal cancer
摘要：
Objective:To analyze the effect of neoadjuvant chemotherapy on malignant molecule levels in tumor tissue and serum of patients with locally advanced resectable colorectal cancer. Methods:A total of 86 cases of patients with locally advanced resectable colorectal cancer were selected and randomly divided into observation group and control group. Control group of patients received traditional postoperative chemotherapy and observation group of patients received preoperative neoadjuvant chemotherapy and traditional postoperative chemotherapy. After one cycle, two cycles and three cycles of neoadjuvant chemotherapy, serum samples were collected to determine the levels of malignant molecules; after surgical resection, the tumor tissues were collected to determine the expression levels of malignant molecules. Results:After one cycle, two cycles and three cycles of neoadjuvant chemotherapy, serum VEGF, Cath-D, MCP-1, ICAM-1, VCAM-1, sIL-2R and IL-18 levels of observation group were significantly lower than those of control group; after surgical resection, Beclin-1 and Caspase-3 mRNA expression levels in tumor tissue of observation group were significantly higher than those of control group, and mTOR, Livin and MTA1 mRNA expression levels were significantly lower than those of control group.Conclusion: Neoadjuvant chemotherapy can effectively inhibit the malignant degree of locally advanced resectable colorectal cancer and inhibit the expression of malignant molecules, and it is of positive significance in terms of improving overall treatment effect.
