A case of resectable pancreatic metastasis from sigmoid colon cancer

Abstract

A 76-year-old man with sigmoid colon cancer had a sigmoidectomy in 1997. Subsequently, he had two pulmonary metastasis resections. In February 2006, abdominal CT scan showed a tumor located in the pancreatic body ; endoscopic retrograde pancreatography showed stenosis of the main pancreatic duct in the pancreatic body. With a diagnosis of primary pancreatic cancer or metastatic pancreatic tumor, a distal pancreatectomy was done in April 2006. On pathology, a metastatic colon cancer was diagnosed. The patient is alive with no signs of recurrence 3 years after the distal pancreatectomy. In colorectal cancer patients, resectable pancreatic metastasis is very rare. In fact, only 32 cases, including this case, have been reported in Japan.
