Abstract

Manipulation of hepatic blood flow may improve drug delivery to hepatic tumour. Somatostatin and its long acting analogues are known to elicit effects upon hepatic and splanchnic blood flow in experimental animals and patients with portal hypertension. This study investigates the effects of SMS 201-995 (sandostatin) infusion on hepatic, splanchnic and tumour blood flow in an experimental model of liver metastases. Hepatic tumour was induced by the intraportal inoculation of 10(6) HSN sarcoma cells and blood flow measured using the dual reference microsphere method before and after infusion of SMS 201-995. There was a significant decrease in hepatic arterial flow and a significant increase in the tumour:liver blood flow ratio associated with a marked reduction in blood flow to normal hepatic parenchyma. Portal venous inflow and tumour blood flow were not significantly affected. SMS 201-995 infusion may lead to preferential delivery of concomitantly injected cytotoxic drugs to hepatic tumour. In addition, the reduction in growth of hepatic tumour may be due to a reduction in nutritive, arterial blood flow to hepatic tumour.
