title: European disparities in malignant digestive endocrine tumours survival.
abstract: The aim of this study was to report on malignant digestive endocrine tumours (MDET) prognosis in several European countries. We analysed survival data from 19 cancer registries in 12 European countries on 3,715 MDET diagnosed between 1985 and 1994. The overall 5-year survival rate was 47.5%. It was 58.1% for differentiated MDET and 8.1% for small-cell MDET (p < 0.001), 55.9% for patients under 65 and 37.0% for older patients. Survival rates for small intestinal and colorectal were higher than for the other sites. The 5-year relative survival rates were 60.3% in Northern Europe, 53.6% in Western Continental Europe, 42.5% in the UK, 37.6% in Eastern Europe (p < 0.001). Among well-differentiated pancreatic tumours, 5-year relative survival was 55.6% for insulinoma, 48.4% for gastrinoma, 33.4% for glucagonoma, 28.8% for carcinoid tumours and 49.9% for non-functioning tumours. The relative excess risk of death was significantly lower in Western Continental Europe and Northern Europe and significantly higher in Easter European compared to the UK. MDET differentiation, site, geographic area, age and sex, were independent prognostic factors. Overall, in Europe approximately half of the patients with MDET survive 5 years after the initial diagnosis. Prognosis varies with tumour differentiation, anatomic site and histological type. There are significant differences in survival from MDET among European countries, independently of other prognostic factors.
