Octreotide therapy is expensive, but at present it and other somatosta
tin analogues appear to offer the best opportunity of controlling the
symptoms of flushing and diarrhoea. It may also have other properties
affecting general well-being. The question of whether it changes tumou
r growth remains unanswered and there is no convincing evidence that i
t alters survival. In all published studies the numbers of patients ar
e small and there have been no control groups, However, since no other
drug has yet proved effective against flushing, the somatostatin anal
ogues, including octreotide, remain the treatment of choice for the sy
mptomatic control of the carcinoid syndrome. Octreotide is of great th
erapeutic value pre-operatively and intra-operatively and it is essent
ial that all operating theatres have this drug available for immediate
use. Surgical debulking, if feasible, provides the best outcome poten
tial in carcinoid disease. Present evidence suggests that the place of
octreotide and other somatostatin analogues is in controlling the sym
ptoms of the disease rather than its progress and in ensuring cardiova
scular and respiratory stability during surgical procedures.
