OBJECTIVE: Nonfunctioning pituitary adenomas (NFPAs) are the most common type of pituitary adenomas diagnosed in older patients. However, there are insufficient data regarding the clinical course, risk of regrowth, and long-term prognosis in elderly versus younger patients.
METHODS: This retrospective cohort study observed 105 adult patients with NFPAs diagnosed between 1995 and 2012. Patients were stratified into 3 age groups: 18 to 44 years (29 patients), 45 to 64 years (38 patients), and 65 years and over (38 patients). The impact of age on presenting symptoms, disease course, and outcome was analyzed.
RESULTS: Adenoma size was larger in patients <45 years (mean, 2.9 ± 1.2 cm) compared to patients aged 45 to 64 years and those ≥65 years old (2.3 ± 0.9 and 2.5 ± 0.8 cm, respectively; P = .05), with transsphenoidal surgery being the treatment of choice in all 3 groups (83, 92, and 84%, not significant). After a mean follow-up of 6 years, there were higher recovery rates from hypopituitarism in patients <45 years old (58% vs. 27% and 24%; P = .04). Visual fields improved in most affected patients in each group following surgery (74, 94, and 86%), with a trend toward more full normalization in the youngest age group (58% vs. 44% and 41%; P = .09). There were no significant differences in the risk of remnant growth (29 to 39%), rates of radiation therapy, or need for repeated surgeries. There was no disease-related mortality.
CONCLUSION: Elderly patients with NFPA have lower rates of recovery from hypopituitarism after treatment compared to younger patients, but the rates of regrowth and need for salvage surgery are similar.
