Regression of hepatocellular carcinoma spontaneous or herbal medicine related?

Hepatocellular carcinoma is one of the most common causes of death from cancer in Taiwan. Treatments for this disease include surgical resection, transcatheter arterial embolization, chemoembolization and systemic chemotherapy. Without treatment, the prognosis of hepatocellular carcinoma is poor, and mortality continues to be significant even in patients with small tumors detected during follow-up. For patients in Taiwan with advanced hepatocellular carcinoma, traditional herbal medicine is frequently used. However, neither the overall prevalence of this therapy nor its efficacy has been studied systematically. Spontaneous regression of cancer, although rare, may occur, but the mechanism leading to regression is still far from understood. Here, we report a case of hepatocellular carcinoma with complete regression after taking herbal medicine. We cannot be certain how significant the herbal preparation was in the regression of the hepatocellular carcinoma, but the regression of the tumor provides us a reason and hope for further research.
