AbstractThe increase in life expectancy along with technological advances has translated into a higher number of pituitary adenomas (PA) diagnosed from the age of 65. In the elderly, symptoms related to comorbidities might overlap with endocrine dysfunction, in addition to increasing anesthetic and surgical risks. This study aimed to compare baseline clinical and tumor features between patients with PA from different age groups: younger adults (YA), 18 to 64 years, and older adults (OA), ≥65 years. As secondary outcomes, we also intended to assess: clinical characteristics and tumor features in patients undergoing surgical intervention and surgical data and complications in patients undergoing transphenoidal surgery (TSS). This retrospective cohort study included patients diagnosed with PA in adulthood divided into YA and OA groups. The secondary outcomes were evaluated in the subgroups: patients who underwent pituitary surgery and patients specifically submitted to TSS, who had completed postoperative follow-up ≥ 6 months until July/2020. A total of 401 patients were included, 327 (81.5%) in the YA and 74 (18.5%) in the OA group. Hormone-secreting effects were more common in the YA group (P < .001) and mass effects in the OA group (P = .070). The prevalence of hypertension and diabetes was higher in the OA group (P = .002, P = .011). A larger proportion of nonfunctioning (NF) PA and prolactinomas was found in OA (P < .001) and YA (P = .012), respectively. Macroadenomas were more common in the OA group (P < .001). No differences were found in terms of invasiveness. In the secondary outcome analysis, there was a higher prevalence of NF-PA in those who underwent pituitary surgery. The rate of TSS-related complications was similar between the groups for major, minor and endocrine/electrolyte complications. OA-PA clinically differ from the younger: tend to present more frequently with chronic comorbidities and less frequently with hormone-secreting effects, are more often NF and larger in size without a significant increase in invasiveness. The TSS results were reassuring, proving to be equally safe for the elderly.Copyright © 2022 the Author(s). Published by Wolters Kluwer Health, Inc.
