Background: Increased life expectancy and wider availability of neuroimaging lead to increase in diagnosis of acromegaly in elderly patients, after the age of 70. Delay in diagnosis is attributable to milder symptomatology, higher prevalence of comorbidities and symptoms overlapping with normal aging process.
Objective: To investigate clinical characteristics, presenting symptoms, comorbidities and treatment modalities of acromegaly in patients diagnosed after the age of 70.
Methods: Eleven patients with acromegaly diagnosed after the age of 70 (9 females, 81.8%) were identified from the group of 121 patients with pituitary adenoma (PA) diagnosed after the age of 70 (9.1%), in the PA Database (n=1442, 0.76%) of the Department of Neuroendocrinology for the past 18 years. Gender, age at diagnosis, tumor size, presenting signs and symptoms, presence of comorbidities and treatment modality were analyzed.
Results: Mean age at diagnosis was 73.5 ± 0.8 years (range: 70-78). All patients had two or more comorbidities (median 4). Six patients (54.5%) had microadenomas, two (18.2%) had mesoadenoma, while three (27.3%) had macroadenomas. Ten patients (90.9%) had typical acromegalic clinical symptoms and signs, while one male with the largest PA (3cm in diameter) presented with neurologic symptoms (headache, instability, vertigo). Arterial hypertension was diagnosed in nine patients (81.8%), cardiomyopathy and valvular heart disease in six (54.5%), diabetes and dyslipidemia in five (45.5%). One patient had breast cancer. One patient with pituitary macroadenoma had hypopituitarism and was replaced with hydrocortisone and levothyroxine. Baseline IGF-1 was 594.7 ± 65.7 ng/ml. Five patients (45.5%) underwent transsphenoidal surgery, without complications, with significant IGF-1 decrease (573.6 ± 148.4 ng/ml preoperatively vs 159.1 ± 45.2 ng/ml postoperatively). Six patients (54.5%) were medically treated with long-acting somatostatin analogues, with favorable therapeutic response after 19.5 ± 9.6 months of therapy (IGF-1 612.3 ± 31.6 ng/ml before vs. 168.5 ± 30.3 ng/ml upon treatment).
Conclusion: Recognition of acromegaly in the elderly may be challenging and delayed due to milder symptoms overlapping with aging and comorbidities. The prevalence of the elderly among newly diagnosed acromegaly patients is expected to expand. Further studies are needed to define optimal diagnostic and therapeutic management appropriate to patients advanced average age.
