A 60-year-old woman was diagnosed with a rectal neuroendocrine tumor(NET)with SM invasion.We performed laparoscopic low anterior resection with D3 lymph node dissection.Pathological findings were rectal NET, G1, pSM(9,000 mm), ly0, v0, pN0, PM0, DM0, pR0, pStage I .Four years and 6 months later, contrast enhanced abdominal computed tomography (CECT)and contrast enhanced magnetic resonance imaging revealed multiple liver metastases.The tumors were unresectable because they were bilobar; therefore, we performed transcatheter arterial chemoembolizaion(TACE).One month later, CECT showed the lesions had shrunk.The metastases were well controlled via repeated TACE.For unresectable liver metastases from rectal NET, TACE can be an effective treatment.
