Clinical trial of intraoperative intraperitoneal perfusion of raltitrexed in patients with colorectal cancer
Objective To explore the application effect of intraoperative intraperitoneal perfusion of raltitrexed in patients with colorectal cancer.Methods The clinical data of patients with colorectal cancer were retrospectively analyzed.According to different treatment using cohort methods,patients were divided into control group and treatment group.Both groups underwent five-hole laparoscopic radical resection of colorectal cancer.The control group was given intraperitoneal irrigation of warm 0.9％NaCl 2 000 mL before abdominal closure.On the basis of control group,treatment group was given intraperitoneal perfusion of 0.9％NaCl 500 mL+raltitrexed 4 mg.The tumor indexes and liver-kidney function before and after surgery,postoperative recovery,complications and survival at 1 year after surgery were compared between the two groups.Results There were 40 cases in control group and 40 cases in treatment group.During postoperative chemotherapy,levels of carcinoembryonic antigen(CEA)in treatment group and control group were(9.50±2.17)and(11.47±2.06)μg·L-1,and levels of carbohydrate antigen 199(CA199)were(127.25±9.31)and(182.64±10.39)U·L-1,and the differences were statistically significant(P＜0.05).Before and at 1 d after surgery,glutamic-pyruvic transaminase(GPT)levels in treatment group were(17.12±4.57)and(21.33±5.42)U·L-1,and glutamic-oxaloacetic transaminase(GOT)levels were(17.03±3.54)and(19.15±4.28)U·L-1,and the differences were statistically significant(P＜0.05).There was no significant difference in postoperative recovery time of intestinal function,hospitalization time or incidence of complications between the two groups(P＞0.05).At 1 year after surgery,disease-free survival in treatment group and control group were(7.49±0.98)months and(7.01±0.95)months,and the differences was statistically significant(P＜0.05).There was no significant difference in overall survival between the two groups(P＞0.05).Conclusion Intraoperative intraperitoneal perfusion of raltitrexed can effectively reduce levels of tumor markers and delay disease progression in patients with colorectal cancer.However,it will cause the reversible increase of GPT and GOT.
