gemcitabine with oxaliplatin (gemox) in patients with advanced hepatocellular carcinoma after failure of sorafenib treatment

Conditions: Hepatocellular Carcinoma, Unresectable, Advanced

Summary: the purpose of this study is to test the safety of gemcitabine and oxaliplatin regimen and to see its effects on sorafenib treatment failed hepatocellular carcinoma patients.

patients who progressed after or cannot tolerate sorafenib treatment. patients who cannot receive sorafenib for other reason are also permitted. treatment is given in cycles, each cycle is 2 weeks long. tumor measurements by ct and/or mri will be repeated every 3 cycles. patients will continue to receive study treatment as long as there is no disease progression or unacceptable side affects.
