Role of chemoembolization in synchronous liver metastases from pancreatic endocrine tumours

Endocrine tumours of the pancreas, even in case of liver involvement, are g enerally characterized by a slower evolution and a better prognosis, if com pared with ductal carcinoma, This fact gives reason to a radical surgical a pproach, whenever possible, and to the research of any effective adjuvant t reatment. For this purpose, hepatic transarterial chemoembolization (TACE) has been proposed in recent years for the treatment of metastatic endocrine tumours. Out of 80 patients suffering from endocrine tumours of the pancre as, observed between January 1985 and December 1996, 28 (35%) presented liv er metastases at the time of diagnosis. Twelve of these patients were submi tted to palliative resection of pancreatic tumour and one or more cycles of TACE. Overall survival was 50% (6/12); median survival was 35.4 months (ra nge 4-75). These results suggest that chemoembolization, combined with surg ical resection of primary malignancy, appears to be able to control the dis ease for a certain time and to increase the survival rate.
