OBJECTIVES

Investigate the survival of patients with stage III colorectal cancer (CRC) treated with immediate postoperative intraperitoneal chemotherapy.

METHODS

The clinical data of 195 patients with stage III CRC admitted to The First Affiliated Hospital of Wenzhou Medical University from June 2017 to June 2018 were retrospectively analyzed. The patients were divided into an observation group and a control group, both groups were treated with the routine laparoscopic radical operation, on the basis of which, the patients in the observation group were treated with intraperitoneal perfusion chemotherapy during the operation. The local recurrence, abdominal cavity metastasis, and liver metastasis were followed up, and the time of disease recurrence and total survival were recorded.

RESULTS

The survival analysis showed that there was a significant difference in progression-free survival (χ 2 = 5.416, P = 0.020) and overall survival (χ 2 = 4.673, P = 0.031) between the observation group and the control group.

CONCLUSIONS

During laparoscopic radical resection of CRC, the use of intraperitoneal chemotherapy with raltitrexed can achieve satisfactory results and improve the survival rate of patients with stage III CRC, perioperative use of raltitrexed has been shown to be beneficial in terms of overall survival and progression-free survival.
