A long-term survival case of multiple hepatocellular carcinoma with metachronous lymph node metastasis.
A long-term survival case of multiple hepatocellular carcinoma (HCC) with metachronous metastasis to a lymph node is reported. The patient, a 66-year-old woman, had two primary HCC nodules, one each in the left and right hepatic lobes, which were resected. She developed a lymph node lesion and a secondary HCC 45 and 62 months after the first operation, respectively. She has been well for the 7 years since the first operation despite undergoing hepatic resection for HCC twice as well as lymph node resection. Clonal analysis, based on the methylation pattern of the X chromosome-linked androgen receptor gene, suggested that the two primary tumors were multicentric and that the lymph node lesion had arisen by metastasis from the primary tumor in the right hepatic lobe.
