A pilot study showed that octreotide can prolong survival time of patients with HCC. Due to methodological deficiencies the results of this pilot study will be re-evaluated by comparison of octreotide versus placebo primarily regarding to the global survival time and secondarily concerning the costs, side effects, patient compliance and quality of life as well as the Somatostatin receptors in the tumor tissue and its prognostic relevance in both groups with 108 patients with hepatocellular carcinoma.
