Hepatocellular carcinoma patients showing long-term complete responses to chemoembolization.
The objective was to evaluate hepatocellular carcinoma (HCC) patients showing a long-term complete response (CR) to chemoembolization. We defined the criteria of CR as normalized tumor marker, no enhanced tumor in diagnostic images, and no tumor cells found at autopsy. Five HCC patients showing long-term CR to chemoembolization were evaluated. The CR period ranged from 3.5 to 7 years (mean, 5.7 years). The survival period ranged from 3.5 to 9 years (mean, 6.7 years). Four cases (80%) were stage IV according to the TNM classification due to a portal tumor thrombus. The liver function was rated as Child's A in four cases (80%). Long-term CR to chemoembolization can be achieved even in some advanced HCC cases with a tumor thrombus. We speculate that the good antitumor effect is brought about by the stagnation of both the arterial and portal blood flows to the HCC. Good liver function is also considered to be an important factor for long-term CR and a long survival period. If the liver function is good, advanced HCC with a portal tumor thrombus should be treated aggressively with chemoembolization.
