ROLE OF OCTREOTIDE IN THE TREATMENT OF PANCREATIC-CANCER

Prognosis in patients with advanced pancreatic cancer is dismal. There has been no effective therapy for these patients so far. Somatostatin and its analogues have been proven to be potent inhibitors of experimental pancreatic cancer. Tumor inhibition is supposed to be mediated directly by somatostatin-binding sites or indirectly by suppression of growth factors. In two trials the value of the new somatostatin analogue octreotide in a low-dose (3 x 100 mu g/ day) and a high-dose (3 x 2,000 mu g/day) protocol was evaluated in patients with advanced pancreatic cancer. Median survival of the patients with a low-dose protocol was 3 months. However, the treatment of pancreatic cancer with a high-dose protocol revealed a median survival of 6 months and stable disease in 4/10 patients. According to quality of life scoring 4 patients showed values comparable to healthy controls. Octreotide therapy with a high-dose protocol is a promising experimental therapeutic approach to advanced pancreatic cancer.
