Surgical treatment of metastatic hepatic cancers

: Main primary sites of hepatic metastatic cancers were the stomach, colon, pancreas and esophagus. Those were found in 16.1% of 335 stomach cancer, 11.9% of 270 colon cancer, 27.1% of 70 pancreas cancer and 3.8% of 131 esophageal cancer at the time of operation. However, the metastatic lesions were resectable in 13%, 43%, 0% and 20%, respectively. Prognosis after hepatectomy was favorable only in colon cancer. 7 of 13 patients who underwent resection of the colon cancer and hepatic metastases are still surviving. The others all died. In inoperable cases, chemotherapy, especially intrahepatic arterial infusion, prolonged the survival time for months.
