OBJECTIVES: The aim of this study was to investigate the level of @entity148 in @entity1 with a primary @entity1313 and to analyse the effect of @entity5 laterality and histology on the level of @entity148 . Recurrent measurements were assessed preoperatively, three months, and one year after operation. METHODS: The study population consisted of 101 @entity1 with a primary @entity1313 from unselected and homogeneous population in northern Finland. The @entity1 were studied preoperatively with CT or MRI to determine the location of the @entity5 . The histology of the @entity5 was defined according to WHO classification. The level of @entity148 was obtained by Crown-Crisp Experiential Index (CCEI) scale. RESULTS: The @entity1 with a @entity5 in the right hemisphere had statistically significantly higher mean @entity148 scores compared to the @entity1 with a @entity5 in the left hemisphere before surgery of the @entity5 . By three months and by one year after surgical resection of the @entity5 , the level of @entity148 declined in @entity1 with a @entity5 in the right hemisphere. A corresponding decline was not found in @entity1 with a @entity5 in the left hemisphere. According to laterality by @entity5 histology, the level of @entity148 decreased significantly in male and female @entity1 with a @entity11 in the right hemisphere, but a corresponding decline was not significant in the female @entity1 with a @entity1653 in the right hemisphere. Decreased level of @entity148 was not found in @entity1 with @entity11 or @entity1653 in the left hemisphere by follow up measurements. CONCLUSIONS: Primary @entity1313 in right hemisphere is associated with @entity148 . The laterality of @entity148 seems to reflect the differentiation of the two hemispheres. The level of @entity148 declined after operation of right @entity5 , approaching that of the general population. The effect of right hemisphere @entity11 on @entity148 deserves special attention in future research.
