Context and ObjectiveNonfunctioning pituitary adenomas (NFPAs) are the most common subtype of pituitary tumour. Hypopituitarism is observed in NFPAs due to tumour- or treatment-related factors and may increase mortality risk. Here, we analysed the associations of hypopituitarism, hormone replacement and mortality in a large NFPA cohort derived from two large European centres.
Design, Setting and ParticipantsCase note review of all patients treated for NFPA in University Hospitals Birmingham and Beaumont Hospital Dublin between 1999 and 2014 was performed.
Main Outcome MeasuresClinical presentation, treatment strategies, pituitary function and vitality status were recorded in each patient. A multivariate Cox regression model was used to examine the association between hypopituitarism, hormone replacement and premature mortality.
ResultsA total of 519 patients were included in the analysis. Median duration of follow-up was 70 years (05-43). A total of 81 deaths were recorded (156%). On multivariate analysis, adrenocorticotropic hormone (ACTH) and gonadotropin (Gn) deficiencies were associated with an increased relative risk of death (OR 226, 95% CI 115-447, P = 001 and OR 256, 95% CI 110-596, P = 001, respectively). Increased hydrocortisone (HC) (P-trend = 002) and lower levothyroxine (LT4) doses (P-trend = 003) were associated with increased risk of death. Mortality increased with the degree of pituitary failure observed (P-trend = 004).
ConclusionACTH and gonadotropin-deficient patients have higher mortality rates compared to those with intact hormonal axes. Excessive HC and suboptimal LT4 replacement may also increase risk of death. Complex associations between hormone deficiency and replacement underpin the increased mortality risk in NFPA patients.
