A long-term survival case of multiple hepatocellular carcinoma with metachronous lymph node metastasis

Surgical Resection of Metachronous Lymph Node Metastasis From Hepatocellular Carcinoma: Three Case Reports and Review of the Literature

The prognosis for hepatocellular carcinoma (HCC) patients with lymph node (LN) metastasis is generally poor, and no consensus has yet been reached on the optimum treatment strategy. We observed 3 cases involving patients with HCC and associated metachronous LN metastasis, who benefited from surgical resection of the metastatic LNs. Each of the 3 patients had solitary LN metastasis for which selective LN resection was performed, and all had C-type cirrhosis as a background disease. There were no other uncontrolled lesions at the time of LN resection. However, additional treatments were required in cases 1 and 3 to control intrahepatic lesions that recurred following the lymphadenectomy. The overall survival in cases 1 and 3 has been >5 years, with case 1 still under observation. Case 2 also remains under follow-up at 6 months after surgery. Surgical resection could be a beneficial strategy for treatment of metachronous LN metastasis arising from HCC in some cases, particularly those involving a solitary LN metastasis with no other uncontrolled lesions.
