Abstract
Effective, non-invasive, palliative strategies for symptomatic malignant ascites are unavailable. This trial explored whether octreotide, an inhibitor of vascular endothelial growth factor, a putative mediator of ascites, prolongs the interval to next paracentesis. After a baseline paracentesis and a test of short-acting agent, patients with symptomatic ascites were randomly assigned to long-acting octreotide (Sandostatin LAR®) depot 30 mg intramuscularly every month versus 0.9% sodium chloride administered similarly. Patients were then monitored for recurrent, symptomatic ascites. Thirty-three patients were enrolled: 16 assigned to the octreotide and 17 to the control arm. The median time to next paracentesis was 28 and 14 days in the octreotide and placebo arm, respectively (p = 0.17). After adjustment for extracted ascites volume and abdominal girth change, no statistically significant difference between the groups was observed (hazard ratio = 0.52, with a 95% confidence interval of 0.21-1.28; p = 0.15, per Cox model). Octreotide-treated patients described less of abdominal bloating (p = 0.01), abdominal discomfort (p = 0.02), and shortness of breath (p = 0.007) at one month, although other quality of life symptoms were comp...Continue Reading
