Brief Summary:
The standard treatment for hepatocellular carcinoma (HCC) is surgery, such as, by hepatic resection or liver transplantation, but less than 20% of HCC patients are suitable for surgery. In the remaining patients with inoperable and advanced HCC, trans-arterial chemo-embolization (TACE) has been widely used but TACE alone rarely produces complete response and commonly develops recurrence. Recently several small studies reported high tumor response and local control rate after stereotactic body radiotherapy (SBRT) alone or with TACE for inoperable HCC. A single institution phase II trial with SBRT for inoperable HCC after incomplete TACE at Korea Cancer Center Hospital showed promising results: the overall response rate of 73% and 2-year local control rate of 95%. They reported severe gastrointestinal toxicity of 11% because there was no normal tissue constraint for gastrointestinal tract and dosage to gastrointestinal tract was restricted to the lowest levels possible. In addition, they found that the presence of gastroduodenal ulcer before SBRT was significantly influenced on severe gastrointestinal toxicity. Based on this study, we will conduct a multicenter phase II trial on maintenance of treatment results and reduction of severe treatment related toxicity below 5%. To achieve this, we strictly apply normal tissue constraints. Secondly, we will do Esophagogastroduodenoscopy (EGD) before SBRT to evaluate gastroduodenal ulcer. After then, we will apply the normal tissue constraint of gastrointestinal tract according to gastroduodenal ulcer.
