RESUMO
Treatment options for advanced hepatocellular carcinoma (HCC) remain limited. Recently, octreotide has been proposed for therapy, although its efficacy remains controversial. Thus, the aim of this open-label pilot study was to evaluate the response of HCC to long-acting octreotide (Sandostatin LAR). Thirty patients were enrolled for this prospective 2-year trial. Initially, patients were given short acting octreotide to ensure drug tolerability. Thereafter, patients received long-acting octreotide 30 mg IM every 4 to 6 weeks. Measurable disease was assessed at 3-month intervals. Five of 30 patients were unable to tolerate the test dose, and 1 patient was reevaluated and underwent hepatic resection. The remaining 24 patients, who received long-acting octreotide, all had advanced stage of disease with multifocal-massive morphology (67%), vascular thrombosis (63%), or extrahepatic spread (17%), but well compensated liver disease. The treatment was well tolerated, except for diarrhea. Median time to tumor progression was 3.6 months, and median survival was 5.1 months. Seven patients (29%) had stable disease (median duration of 8.0 months) with 2 patients demonstrating disease stability for 24 months. In conclusion, although occasional patients appear to have stable disease on long-acting octreotide therapy, overall the beneficial response in terms of time to tumor progression and survival is limited.
