The use of SMS 201-995 (somatostatin analogue) in insulinomas. Additional case report and literature review.

A 76-year-old man, a known case of insulinoma, was well controlled for 11 days on 50 micrograms SMS 201-995 every 12 h; clinical recovery was immediate with normalization of blood sugars and C-peptide levels. The potential value of this new drug in the management of insulinomas is illustrated by this case and by 11 additional case reports which are reviewed. A rise in C-peptide levels during treatment without concomitant hypoglycaemia might be the first indication of a loss of control.
