There were 4 cases of mesenteric metastases, 1 case of abdominal wall metastasis, 1 case of mesenteric plus rectal wall metastasis, and 1 case of colon and mesenteric metastasis. The 1-year, 3-year, and 5-year disease-free survival (DFS) rates were 31.1%, 23.3%, and 11.7%, respectively. The 1-year, 3-year, and 5-year overall survival rates were 93.3%, 28.7%, and 19.1%, respectively. Three patients are currently surviving disease-free, with survival times of 130.4 months, 43.3 months, and 9.4 months, respectively.Conclusion: Although the current guidelines do not recommend surgical resection as the preferred treatment for postoperative abdominal metastases of HCC, surgical resection is recommended for patients with limited or solitary metastasis in the abdominal cavity.Keywords: hepatocellular carcinoma, postoperative recurrence of HCC, intra-abdominal metastasis, disease-free survival, overall survival
