An analysis of 8305 cases of carcinoid tumors

Carcinoids appear to have increased in incidence in the past 20 years. In part, this may be due to different surgical rules of the various registries, improved diagnostic technology, and increased awareness. A cumulative analysis of all types of carcinoid tumors in the SEER group indicates that in 45.3% metastases are already evident at the time of diagnosis. The overall 5-year survival rate of all carcinoid tumors regardless of site was 50.4% +/- 6.4%.
