Between 1987 and 1989 we treated 18 patients with advanced pancreatic adenocarcinoma with a long acting LH-RH analogue: triptorelin. Seventeen patients were evaluated. We obtained no objective responses. The median survival time was 4.5 months. The treatment was well tolerated without any major secondary effects. The absence of dosage of hormonal receptors did not allow the selection of hormone sensitive patients. The future study of hormone therapy will analyse the pancreatic hormonal receptors.
