title: [A Case of Retroperitoneal Recurrence and Left Kidney Metastasis Occurring Four Years after Laparoscopy-Assisted Surgery for Sigmoid Colon Cancer].
abstract: A 67-year old woman underwent laparoscopy-assisted high anterior resection for sigmoid colon cancer. A histopathological examination revealed no lymph node metastasis, but extramural cancer deposits were present. Four years later, enhanced computed tomography revealed recurrence in the retroperitoneum and metastasis to the left kidney. A left nephrectomy and left hemicolectomy were performed. A year after the second operation, computed tomography revealed metastasis to the lung. Histopathological reexamination for extra-lymph nodal spread after the first operation revealed venous involvement. Generally, colon cancer with extra-lymph nodal spread has a higher risk of retroperitoneal recurrence, and venous involvement leads to a poor prognosis. We describe our case with the known report.
