Context. The literature concerning the health-related quality of life (HRQoL) of patients with surgically treated PA is controversial.
Objective. To describe the long-term HRQoL of surgically treated patients in all PA classes. Design and subjects. The 15D, a
generic HRQoL instrument producing a 15-dimensional profile and a single 15D index score (a difference ≥0.03 on a 0-
1 scale is considered clinically important), was used to assess the HRQoL of a 13-year surgical cohort of PA patients in
Northern Finland. Results and Conclusion. Nighty-eight eligible consecutive patients with surgically treated PA were studied
at an average of 6.3 years after their latest pituitary operation. The average postoperative 15D profiles in patients with non-
functioning PA and in acromegalics without GH-suppressive medical treatment were similar to those of the age-standardized
general population. However, after this rather long followup, the mean 15D score and the number of statistically significant 15D
dimension impairments, compared with those of their reference population, were 0.11 and 9/15, 0.10 and 3/15, and 0.08 and 7/15
for Cushing’s disease, acromegalics needing somatostatin analog, and prolactinoma patients, respectively. Hypopituitarism with
replacement medication was not associated with impaired HRQoL. The somatostatin-analog-associated HRQoL finding warrants
further clinical research.
1. Introduction
Pituitary adenomas (PAs) are benign neoplasms of the ade-
nohypophysis, with an overall annual incidence of about
4/100 000. Prolactin-secreting prolactinomas and clinically
non-functioning (NF) PAs are the most common PA classes,
followed by, with decreasing incidence, GH- (acromegaly),
ACTH- (Cushing’s disease, CD), and TSH-secreting (thy-
rotropinoma) adenomas [1]. The treatment objectives in
patients with pituitary adenoma are to eliminate possible
mass effects of the tumor, to normalize possible hormonal
and metabolic disturbances of the patient, and to recover
normal health-related quality of life (HRQoL). Despite the
endocrinologically and radiologically successful treatment of
a hormonally active or non-functioning PA, both physical
and mental adverse effects of the disease may persist thus
causing permanent impairment of HRQoL [2, 3]. In the
literature controversies exist about correlation of metabolic
markers and subjective well-being of the patient, especially
in acromegaly [4–8]. Also, there are controversies as to
which PAs are associated with the most prominent HRQoL
impairments [9, 10], and whether treated NFPAs cause
HRQoL impairment at all [11, 12].
HRQoL assessment is important in clinical practice,
as it gives the clinician information on issues that have
paramount importance for the patients’ everyday life. In
addition, it has been proposed that evaluation of HRQoL
should be combined with hormonal assessment to detect
more sensitively patients’ improvement during augmented
medical therapy in acromegaly [4, 8]. Taking into account
these multiple controversies and the emerged importance of
patients’ subjective morbidity, our objective in this study was
to use a generic, validated HRQoL instrument with domestic
