Objective To investigate the clinical effects of Huaier granule combined with postoperative chemotherapy on recurrence and survival after curative resection of colorectal liver metastasis (CLM). Methods One hundred and twenty-eight patients with CLM who underwent curative resection at the sixth affiliated hospital, Sun Yat-sen University from January 2012 to December 2017 were followed up and analyzed retrospectively. Patients were divided into two groups according to the postoperative adjuvant therapy schedule. An experimental group: Huaier granule combined with chemotherapy (72 cases); a control group: only chemotherapy (56 cases). The following variables of two groups were analyzed: gender, age, carcinoembryonic antigen (CEA) lever, tumor depth, N stage, size of liver metastases, number of liver metastasis, chemotherapy before operation. The patients were followed up to November 2019. The followed up data were used to calculate the survival rate, and analyze the univariate factor and multivariate factor which affecting recurrence and long-term survival. Results The perioperative chemotherapy completion rate of the experimental group was higher than that of the control group. The 3-year and 5-year overall survival rates of the experimental group and the control group were 83.5%, 60.7% and 65.3%, 48.2%, respectively, with a significant difference (p=0.015).The recurrence free survival rates of the two groups were 77.8%, 53.5%, 59.7% and 35.7%, respectively, with a significant difference (p=0.003). Univariate and multivariate analysis showed that CEA level, lymph node metastasis, number of liver metastases and chemotherapy with perioperative completion affecting the postoperative recurrence of patients with CLM, primary tumors with lymph node metastasis, the number of liver metastases and Huaier Granule therapy affecting the overall survival. Conclusions The recurrence and overall survival of CLM after radical resection depend on the tumor burden and chemotherapy. The patients with single liver metastasis, no-lymph node metastasis and Huaier Granule combined with adjuvant chemotherapy, may have long-term survival.
