Papillary ( @entity3557 ) and follicular ( @entity6888 ) @entity259 are rare disorders but are, nevertheless, among the most common @entity5 in individuals below 40 years of age. From the population-based Swedish @entity5 Registry we identified 3,588 individuals with @entity3557 and 1,966 with @entity6888 during 1958-87. Histopathology was determined by examining the original histopathology reports. The relative survival ratio (RSR) was used as the measure of @entity1 survival. Incidence of both @entity3557 and @entity6888 was higher among @entity1 , especially for @entity3557 and particularly during the fertile part of female life. Incidence of @entity3557 increased significantly over time, a trend that was not observed for @entity6888 . Five-year relative survival appeared to be higher for @entity1 diagnosed with @entity3557 compared to @entity6888 , although this difference was almost completely explained by the confounding effect of age. @entity1 with @entity3557 experience lower mortality during the period 7-20 years after diagnosis. Excess mortality was lower among @entity1 , although the magnitude of the difference varied with age and histopathology. In contrast to our perceptions based on clinical practice, we observed no difference in excess mortality between @entity1 diagnosed with @entity3557 and @entity6888 during the years immediately after diagnosis (where the majority of deaths occur). Our data suggest that there may exist a subgroup of @entity259 with superior prognosis diagnosed in @entity1 during the fertile part of female life. Sex hormones may play a role in the etiology of these @entity5 .
