Abstract
|
|
|
Purpose: Sarcomatous hepatocellular carcinoma (HCC) is rare. Therefore, the clinicopathologic characteristics and prognosis after hepatic resection have yet to be clarified. The purpose of this study was to analyze the outcome of sarcomatous HCC patients who underwent surgical resection.
Methods: From January 1997 to May 2005, 11 patients (1.1%) were diagnosed with sarcomatous HCC among 1,005 cases of HCC undergoing resection after pathology and immunohistochemical studies.
Results: All of the cases were male and their mean age was 55.8+/-8.1 years. R0 resection was achieved in nine of the 11 patients. The HCC lesions were classified as stage II in three, stage III in four, stage IVa2 in three, and IVb in one, according to the modified pTNM staging system. Extrahepatic metastases as the initial recurrence occurred in eight patients. Among the 11 patients, 10 died of a disease recurrence and only one is still alive. The overall 3-year survival rate was only 18%.
Conclusion: The prognosis of sarcomatous HCC was very poor, showing widespread extrahepatic metastases and frequent early recurrence regardless of the tumor extent. Since some patients showed prolonged survival after a local recurrence, vigorous postoperative systemic surveillance appears to be beneficial for early detection and timely treatment of localized metastases.
