OBJECTIVES: To study mortality and survival of @entity1 with @entity1737 . METHODS: 290 @entity1 with @entity1737 were studied, including 212 incident cases identified during a comprehensive epidemiological study of @entity1737 in western Denmark 1975-89. Follow up was performed on 31 December 1994. Survival curves were constructed using the life table method. @entity1 data were compared with data from the public Danish population statistics. Death certificates were provided from the National Registry of Death. RESULTS: The annual average crude mortality rate was 1.8 per million (range 1.5-2.2). The @entity1737 related mortality rate ( @entity1737 as underlying or contributory cause) was 1.4 per million (range 1.1-1.8). The age specific mortality rates were low below 50 years. After this age the mortality increased with age in both sexes; after 60 years more rapidly in @entity1 than in @entity1 . The overall survival rates three, five, 10, and 20 years from diagnosis were 85%, 81%, 69%, and 63% respectively. The survival of both sexes was shorter than that of the corresponding Danish population. Old age at diagnosis, a classification in Osserman-Genkins group IIB or III, and the presence of a @entity704 were associated with a less favourable prognosis. The three, five, 10, and 20 year survival rates of thymectomised @entity1 were 94%, 94%, 86%, and 79% respectively. The corresponding figures for the non-thymectomised @entity1 were 78%, 71%, 56%, and 51%. A Cox regression analysis showed that this apparently significant effect of thymectomy was because the thymectomised @entity1 were younger than the non-thymectomised @entity1 . Furthermore, at the time of diagnosis of @entity1737 the non-thymectomised @entity1 had a higher frequency of serious conditions associated with @entity1737 than the thymectomised @entity1 . CONCLUSION: @entity1 with @entity1737 generally have a relative good prognosis although their survival is shorter than that of the corresponding population. Old age, a classification in Osserman-Genkins group III, and the presence of a @entity704 are associated with a less favourable prognosis. In this study, the apparently significant effect of thymectomy was because the thymectomised @entity1 were younger than non-thymectomised @entity1 and because the non-thymctomised @entity1 had a higher frequency of serious conditions associated with @entity1737 .
