Prognosis of Atypical Pituitary Adenomas
Context: Pituitary adenoma is generally indolent, but an aggressive subtype called atypical
 adenoma has uncertain prognosis, and an unclear relationship between prognosis and
 morphology.

 Objective: This study investigated the prognostic factors of this tumor. Design:
 Retrospective analysis. Setting: University and associated hospitals.
Inclusion Criteria:

 -  pituitary adenomas of more than 3 % of Ki67 labeling index surgically treated at
 Tohoku university and associated hospital

 Exclusion Criteria:

 -  pituitary adenomas of less than 3 % of Ki-67 labeling index surgically treated at
 Tohoku university and associated hospital
