Stereotactic Body Radiation Therapy for Hepatocellular Carcinoma

Phase II Multicenter Study of Stereotactic Body Radiation Therapy for Hepatocellular Carcinoma: Toxicity and Outcome

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.

Arms and Interventions

Participant Group / Arm

Intervention / Treatment

Experimental: Stereotactic body radiotherapy; Stereotactic body radiotherapy for unresectable hepatocellular carcinoma after incomplete trans-arterial chemo-embolization

Radiation: Stereotactic body radiotherapy; Total stereotactic Body radiotherapy (SBRT) doses will be 60 Gy in 3 fractionations. Patients receive 3 fractionations separated by >48 hours. At least 700 ml of normal liver (entire liver minus cumulative GTV) should not receive a total dose of > 17 Gy in three fractions. If volume of normal liver does not exceed 700 ml, at least 70% of normal liver should not receive a total dose of > 17 Gy. In patients without gastroduodenal ulcer on Esophagogastroduodenoscopy (EGD) before SBRT, D2ml of gastrointestinal tract should not exceed 35 Gy. In patients with gastroduodenal ulcer on EGD before SBRT, D2ml of gastrointestinal tract should exceed 28 Gy. (D2ml: minimum dose to 2 ml of gastrointestinal tract); Other Names: Stereotactic ablative radiotherapy
