• Median survival [ Designated as safety issue: No ]
  

OBJECTIVES:

Primary

• To verify that long-acting somatostatin analog octreotide (Sandostatin LAR) depot will extend median survival from 5 months to 8.75 months in patients with locally advanced or metastatic hepatocellular carcinoma with a CLIP score of 3 or more.

Secondary

• To document tolerability of this drug in this patient population.

OUTLINE: Patients are stratified according to underlying degree of liver disease as defined by CLIP score classification.

Patients receive short-acting octreotide subcutaneously three times daily on days 1-21 OR days 1-28. If the patient tolerates short-acting octreotide, the first dose of long-acting octreotide (Sandostatin LAR) depot will be given intramuscularly beginning on day 8 OR day 15. Treatment with long-acting octreotide repeats every 28 days in the absence of disease progression or unacceptable toxicity.

After the completion of study treatment, patients are followed monthly for 6 months.

DISEASE CHARACTERISTICS:

• Newly diagnosed or recurrent hepatocellular carcinoma (HCC) as defined by tissue biopsy OR alpha fetoprotein (AFP) > 1,000 ng/mL with compatible mass on CT scan or MRI

  • Recurrence of previously resected HCC will not require tissue confirmation if there is clear radiographic recurrence, in the judgment of the investigator
• Locally advanced OR metastatic disease
• Unmeasurable disease allowed if initial diagnosis was made according to the above criteria and/or recurrence has been confirmed by tissue biopsy or radiological imaging
• CLIP score ≥ 3
• Not a candidate for surgical resection or liver transplant
• Not a candidate for loco-regional therapy (e.g., ablation, embolization, hepatic arterial infusion therapy), but could have received such therapy in the past
• No fibrolamellar HCC
• No clinically apparent central nervous system metastases or carcinomatous meningitis

PATIENT CHARACTERISTICS:

• Life expectancy ≥ 8 weeks
• Karnofsky performance status 60-100%
• Hemoglobin ≥ 8.5 g/dL
• Platelet count ≥ 50,000/mm³
• Total bilirubin ≤ 5.0 mg/dL
• AST or ALT ≤ 5 times upper limit of normal (ULN)
• Creatinine ≤ 2 times ULN
• PT ≤ 28
• INR ≤ 2.5
• No active variceal bleeding within the past 3 months
• No encephalopathy grade 3-4
• No ongoing ethanol or intravenous drug abuse
• Not pregnant or breast feeding

PRIOR CONCURRENT THERAPY:

• See Disease Characteristics
• Any number of prior therapies (e.g., chemotherapy, resection, embolization, or radiofrequency/ethanol ablation therapy) allowed
• No concurrent chemotherapy, radiotherapy, or immunotherapy
