Phase I Study of Image-Guided Radiation Concurrent With Double-Agent Chemotherapy for Hepatocellular Carcinoma

This is a phase I study to evaluate the safety of concurrent chemoradiation combining radiotherapy (IGRT) with two cytotoxic agents, capecitabine and oxaliplatin in patients with advanced or inoperable hepatocellular carcinoma.

In this phase I study, patients with advanced or inoperable hepatocellular carcinoma, or those failed other strategies will be recruited. The primary tumor and nearby metastatic nodes will be irradiated with Image-Guided Radiation Therapy (IGRT) mostly with conventional fractions. During the course, oral capecitabine and intravenous oxaliplatin will be given concurrently. The maximum tolerated dose (MTD) for the two drugs will be determined during escalation according to the occurrence of dose limiting toxicities (DLT).

* Be conscious and could cooperate and comply with protocols for the study, such as simulation, smooth breathing and positioning for radiotherapy.
* Be ready to be followed up.
* Fulfill dosages requirement for targets and dose limits for organs at risk.
* The patient should be under anti-hepatitis-virus therapy if indicated.
* Sorafenib should be discontinued 7 days before the start of irradiation.
* Subjects informed of the diagnosis of advanced HCC who are fully informed about the content of the study by the investigator using the written consent form, and give written consent to participate in the study of their own free will.

Exclusion Criteria:

* KPS≤70.
