Treatment of the Malignant Carcinoid Syndrome

Abstract

We studied the effects of a long-acting analogue of somatostatin (SMS 201-995, Sandoz) in 25 patients with histologically proved metastatic carcinoid tumors and the carcinoid syndrome. This drug was self-administered by subcutaneous injection at a dose of 150 micrograms three times daily. Flushing and diarrhea associated with the syndrome were promptly relieved in 22 patients. All 25 patients had an elevated 24-hour urinary excretion of 5-hydroxyindoleacetic acid (5-HIAA) (mean, 265 mg per 24 hours; range, 14 to 1079), which served as an objective indicator of disease activity. Eighteen of the 25 patients (72 percent) had a decrease of 50 percent or more in their urinary 5-HIAA levels, as compared with the pretreatment values. The median duration of this biochemical response was more than 12 months (range, 1 to greater than 18). Since no serious toxicity was observed, we conclude that SMS 201-995 may be appropriate for use as early therapy in patients with symptoms due to the carcinoid syndrome who have not responded to simpler measures.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
