RADICAL RESECTION OF A METASTATIC LIVER TUMOR NINE YEARS AFTER TOTAL CYSTECTOMY FOR A URINARY BLADDER CARCINOMA-REPORT OF A CASE-

Abstract

This paper describes a case of solitary metastatic liver cancer developed 9 years after a total cystectomy for a cancer of the urinary bladder which was resected radically. A 71-year-old man was admitted to the hospital because he was pointed out an abnormal shadow of the liver at a total medical checkup. Histopathological findings of the liver biopsy were compatible with those of transitional cell carcinoma, and it was considered as a metastasis of the urinary bladder cancer which was treated 9 years before. The liver tumor was radically resected. Metastatic liver tumors usually derive from cancers of the digestive organs, especially from the colon or rectum. The metastatic liver tumors from cancer of the urinary bladder are resected in an extremely low incidence. This is not because liver metastases of the urinary bladder cancer are rare, but because most cases of liver metastasis are accompanied with multiple liver metastasis and other organ metastasis. From our experience with this patient, we have realized the importance of long term monitoring of the pelvic region and remote organs for the presence of metastases, after resection of the urinary bladder due to a cancer, and actual existence of metastatic liver tumor of bladder cancer which can be resected surgically by early discovery.
