Long-term impaired quality of life in Cushing's syndrome despite initial improvement after surgical remission.
ABSTRACT Cushing's syndrome (CS) is associated with symptoms that may impair health-related quality of life (HRQL).
We used the short-form 36 survey to evaluate HRQL in 23 patients with Cushing's disease before and after transsphenoidal surgery (age, 42.7 +/- 12.0 yr; 19 women and four men) and in a cross-section of 343 CS patients (age, 48.2 +/- 14.1 yr; 265 women and 78 men) in remission for up to 25.8 yr after surgery (adrenal, 5%; ectopic, 6%). The z-scores were calculated for short-form 36 domains, and physical (PCS) and mental (MCS) summary scores were compared with those of age- and sex-matched controls (n = 6742).
Active Cushing's disease was associated with low PCS and MCS scores (P < 0.05). Despite residual postoperative impairment, primarily of physical domains, all HRQL parameters improved after treatment with transsphenoidal surgery (3.2 +/- 1.5 yr; P < 0.05). In the cross-section in remission at follow-up, there was a small, but significant (P < 0.05), impairment of both PCS and MCS. A longitudinal postoperative analysis confirmed stable, but impaired, HRQL over time. Logistic regression demonstrated that previous pituitary radiation and current glucocorticoid use had little effect on HRQL outcomes.
CS is associated with impaired HRQL, which partially resolves after treatment. At longer-term follow-up, however, there is residual impairment of HRQL. Determination of modifiable factors that contribute to impaired HRQL may help reduce the physical and psychosocial burden of this disease.

ABSTRACT: Stereotactic radiosurgery (SRS) is a common treatment for recurrent or residual pituitary adenomas. The persistence of symptoms and treatment related complications may impair the patient's quality of life (QOL). The purpose of this study was to examine symptom distress, QOL, and the relationship between them among patients with pituitary tumors who had undergone SRS. This study used a cross-sectional design and purposive sampling. We enrolled patients diagnosed with pituitary tumors who had undergone SRS. Data were collected at the CyberKnife Center at a medical center in Northern Taiwan in 2012. A questionnaire survey was used for data collection. Our questionnaire consisted of 3 parts the Pituitary Tumor Symptom Distress Questionnaire, the World Health Organization Quality of Life Instrument Short-Form (WHOQOL-BREF), and a demographic questionnaire. Sixty patients were enrolled in the study. The most common symptoms reported by patients after SRS were memory loss, fatigue, blurred vision, headache, sleep problems, and altered libido. The highest and lowest scores for QOL were in the environmental and psychological domains, respectively. Age was positively correlated with general health and the psychological domains. Level of symptom distress was negatively correlated with overall QOL, general health, physical health, and the psychological and social relationships domains. The scores in the psychological and environmental domains were higher in males than in females. Patients with ≤6 symptoms had better overall QOL, general health, physical health, and psychological and social relationships than those with >6 symptoms. Symptom distress can affect different aspects of patient QOL. Levels of symptom distress, number of symptoms, age, and gender were variables significantly correlated with patient QOL. These results may be utilized by healthcare personnel to design educational and targeted interventional programs for symptom management to improve patient QOL.PLoS ONE 02/2014; 9(2):e88460. · 3.53 Impact Factor

ABSTRACT: Objective To retrospectively review institutional records of female patients of reproductive age with Cushing's disease (CD) and determine if and how many had been previously diagnosed as having solely PCOS. To determine whether clinical patterns might be useful in identifying appropriate candidates for hypercortisolism screening in women suspected of PCOS. Study Design The study included 50 patients with pathologically proven CD at Oregon Health & Science University, Northwest Pituitary Center between 2006 and 2011. Physical, clinical, and biochemical features for hypercortisolism were compared. Results Of 50 patients with pathologically proven CD, 26 were women of reproductive age. Of these, half had previously been diagnosed with and treated initially solely for PCOS. Hirsutism and menstrual abnormalities were more common in the group with an initial PCOS diagnosis than in the group with an initial CD diagnosis. Conclusions Prolonged exposure to hypercortisolism has been linked with increased mortality and morbidity. Tests for hypercortisolism in all the PCOS cases we report led to an appropriate CD diagnosis. Future research should focus on when and which (if not all) women with suspected PCOS should be tested for hypercortisolism.European journal of obstetrics, gynecology, and reproductive biology 04/2014; · 1.97 Impact Factor

ABSTRACT: Endogenous Cushing's syndrome is an endocrine disease resulting from chronic exposure to excessive glucocorticoids produced in the adrenal cortex. Although the ultimate outcome remains uncertain, functional and morphological brain changes are not uncommon in patients with this syndrome, and generally persist even after resolution of hypercortisolemia. We present an adolescent patient with Cushing's syndrome who exhibited cognitive impairment with brain atrophy. A 19-year-old Japanese male visited a local hospital following 5 days of behavioral abnormalities, such as money wasting or nighttime wandering. He had hypertension and a 1-year history of a rounded face. Magnetic resonance imaging (MRI) revealed apparently diffuse brain atrophy. Because of high random plasma cortisol levels (28.7 μg/dL) at 10 AM, he was referred to our hospital in August 2011. Endocrinological testing showed adrenocorticotropic hormone-independent hypercortisolemia, and abdominal computed tomography demonstrated a 2.7 cm tumor in the left adrenal gland. The patient underwent left adrenalectomy in September 2011, and the diagnosis of cortisol-secreting adenoma was confirmed histologically. His hypertension and Cushingoid features regressed. Behavioral abnormalities were no longer observed, and he was classified as cured of his cognitive disturbance caused by Cushing's syndrome in February 2012. MRI performed 8 months after surgery revealed reversal of brain atrophy, and his subsequent course has been uneventful. In summary, the young age at onset and the short duration of Cushing's syndrome probably contributed to the rapid recovery of both cognitive dysfunction and brain atrophy in our patient. Cushing's syndrome should be considered as a possible etiological factor in patients with cognitive impairment and brain atrophy that is atypical for their age.Neuropsychiatric Disease and Treatment 01/2014; 10:1763-7. · 2.00 Impact Factor

Context: Cushing’s syndrome (CS) is associated with symptoms that
may impair health-related quality of life (HRQL).
Methods: We used the short-form 36 survey to evaluate HRQL in 23
patients with Cushing’s disease before and after transsphenoidal
surgery (age, 42.7 ? 12.0 yr; 19 women and four men) and in a
cross-section of 343 CS patients (age, 48.2 ? 14.1 yr; 265 women and
78 men) in remission for up to 25.8 yr after surgery (adrenal, 5%;
ectopic, 6%). The z-scores were calculated for short-form 36 domains,
and physical (PCS) and mental (MCS) summary scores were com-
pared with those of age- and sex-matched controls (n ? 6742).
Results: Active Cushing’s disease was associated with low PCS and
MCS scores (P ? 0.05). Despite residual postoperative impairment,
primarily of physical domains, all HRQL parameters improved after
treatment with transsphenoidal surgery (3.2 ? 1.5 yr; P ? 0.05). In
the cross-section in remission at follow-up, there was a small, but
significant (P ? 0.05), impairment of both PCS and MCS. A longitu-
dinal postoperative analysis confirmed stable, but impaired, HRQL
over time. Logistic regression demonstrated that previous pituitary
radiation and current glucocorticoid use had little effect on HRQL
Conclusion: CS is associated with impaired HRQL, which partially
resolves after treatment. At longer-term follow-up, however, there is
residual impairment of HRQL. Determination of modifiable factors
that contribute to impaired HRQL may help reduce the physical and
psychosocial burden of this disease. (J Clin Endocrinol Metab 91:

(1, 2). Important functional impairments arising from hy-
percortisolism include muscle weakness, fracture, and car-
diovascular events, which can adversely affect the survival
and well-being of these patients (3). Additional psycholog-
anxiety (4, 5), and cognitive decrements (6). Improved psy-
of hypercortisolism (7, 8). Short-term series have shown sig-
nificant improvements occurring within the first year of
treatment (9). However, longer studies suggest that pro-
longed exposure to high levels of glucocorticoids may cause
long-lasting deleterious effects (10–12).
Although the process of differential diagnosis and man-
agement of CS has been well validated (13), outcomes in
relation to quality of life have received less attention. Im-

groups of patients with Cushing’s disease (CD) alone, with
short duration of postoperative follow-up and in the absence
of an age- and gender-matched control comparison.
We conducted a prospective study of HRQL using the
SF-36 health survey in a cohort of patients with CD before
and after transsphenoidal surgery (TSS). To characterize the
impact on HRQL of successful treatment in CS, we also
performed a cross-sectional analysis of HRQL in a cohort in
long-term clinical remission, which included patients with
The hypothesis was that we would observe improved HRQL
after treatment and that HRQL would be greater with in-
creasing duration of remission from hypercortisolism. We
anticipated lower HRQL in patients with ectopic compared

first author (J.R.L.) used an existing database of approximately 900
patients who had been enrolled in a range of protocols for investigation
and excluded them from a mailing list sent to patients with confirmed
CS. The survey was commenced in 1999, with two subsequent mailings
in 2001 and 2004 to a total of 775 patients. Four hundred eighteen
individuals returned 688 questionnaires; of these, 159 contributed two
or more responses. Group 2 comprised a cross-sectional analysis of the
most recent/latest questionnaire response from 343 subjects who were
deemed to be in postoperative clinical remission. Seventy-five patients
were excluded from this analysis, comprising eight patients who com-
pleted pretreatment responses alone, seven patients with insufficient
follow-up data, and 60 individuals with possible/previously confirmed
recurrence who are described below.
Quality of life
We used the SF-36R (version 2) for assessment of HRQL (16). The
SF-36 is a generic health survey that has been widely validated and used
in an international context to evaluate self-reported domains of health
status (16). The SF-36 survey consists of a 36-item questionnaire that
includes eight components of HRQL: physical functioning, role limita-
tions due to physical health, bodily pain, general health, vitality, social
functioning, role limitations due to emotional health, and mental health.
These eight domains formed two broader health dimension scales: a
physical component scale (PCS) and a mental component scale (MCS).
two health dimensions by setting the general population mean at 50 ?
10 (mean ? 1 sd). To control for any difference in age and gender
between the population norms and our sample, we compared our sam-
studied by Ware et al. (16). To do this, we created a deviation score for
each patient, calculated as the absolute difference between the individ-
ual’s score and the appropriate age/gender norm. This score was then
standardized to a z-score by dividing it by the sd for that age/gender
sds the patient deviated from his/her own age/gender population
norm. In our analyses, we present data using both the SF-36 standard-
ized score as well as this age/gender-controlled deviation score.
In addition to the SF-36 quality of life dimensions, cognitive function
was assessed with the Medical Outcomes Study cognitive functioning
scale (17). The Medical Outcomes Study quality of life assessment was
the precursor to the SF-36; however, the cognitive functioning scale was
omitted from the SF-36 in the interest of brevity. We elected to include
the cognitive functioning scale, because this may be a particularly rel-
evant dimension for this population.
Demographic variables and symptom checklist
The survey instrument included demographic data (age, gender,
marital status, and highest grade of educational attainment), diagnosis,
primary treatment, and subsequent treatments (surgery, medicine, or
radiation) since discharge. The subjects were asked to indicate whether
they had experienced a recurrence or were currently cured of CS and to
indicate whether they were currently taking hydrocortisone, pred-
nisone, dexamethasone, mitotane, or ketoconazole. All patients were
requested to provide details of the most recent laboratory screening for
objective assessment of remission status. Patients also were asked to
indicate whether they were currently experiencing any of 42 items on a
checklist containing signs and symptoms associated with CS.
Evaluation of long-term remission
The posttreatment cross-sectional analysis excluded patients with
previously confirmed recurrence of CS as determined from our internal
records (n ? 34) and patients who indicated that they were not cured
(n ? 19). Patients with persistent hypercortisolism (n ? 2) or who
required ketoconazole (n ? 4) or mitotane (n ? 1) treatment were
excluded. These responses were cross-checked with our records and
with returned results of biochemical screening for examination of re-

quencies were generated for other variables. Significance was assumed

to examine differences in demographic variables. Only patients with
both pre- and posttreatment responses were included in the intraindi-
of z-scores for each group and domain were calculated. A mean z-score
(effect size) less than 0.20 was considered clinically nonsignificant, a
z-score in the range 0.2–0.5 was classified as small, a z-score in the range
0.5–0.8 as moderate, and a z-score greater than 0.8 as large (18, 19).
Spearman’s rank test was used to examine correlations between SF-36
outcomes and continuous demographic variables.
An analysis of the effect of time from treatment on HRQL was con-
ducted within group 2, which included serial observations from indi-
vidual respondents. However, if a subject contributed more than one
in that time period was used. Data were analyzed using mixed model
analysis of repeated measures, followed by post hoc testing for pairwise
comparisons among the times from treatment, using Statistical Analysis
System (SAS) version 8 software (SAS Institute, Inc., Cary, NC).
Logistic regression analysis was used to evaluate the relationship of
the physical symptom score, time from treatment, glucocorticoid use,
previous pituitary irradiation (XRT) and deviation of greater than 0.5 sd
in PCS and MCS domains below the normative mean. Testing was
performed using the statistical package for social science (SPSS version
12 for Windows, release 09.04, 2003, SPSS, Inc., Chicago, IL) and Graph-
Pad PRISM version 4.00 for Windows (GraphPad, San Diego, CA;
Group 1: HRQL in CD before and after TSS
Patients with active CD (Table 1) had low PCS, MCS, and
low individual SF-36 domain z-scores compared with age-
and MCS scores improved from 32.6 ? 10.5 and 38.8 ? 12.5
to 45.8 ? 12.7 and 50.5 ? 9.6, respectively (P ? 0.001), at
postoperative follow-up (mean, 3.2 ? 1.5; range, 0.7–5.4 yr;
Table 2). All individual SF-36 domains improved after TSS
function after treatment (56.2 ? 25.8 vs. 73.2 ? 29.4; P ? 0.02)
Postoperatively, scores for bodily pain (P ? 0.5), vitality
(P ? 0.4), social functioning (P ? 0.1), role limitations due to
emotional health (P ? 0.6), general health (P ? 0.4), mental
health (P ? 0.5), and the mental summary scores (P ? 0.8),
improved to levels similar to U.S. population norms. In con-
trast, physical functioning (P ? 0.04), role limitations due to
physical health (P ? 0.049) and physical summary (P ? 0.04)
scores remained significantly below U.S. population norms.

(CD, 89%; adrenal, 5%; ectopic, 6%) in the posttreatment
cross-sectional sample were similar in terms of gender, ed-
ucation, and marital status to those in the posttreatment arm
of group 1 (Table 1). Compared with group 1, the patients
were older by approximately 6 yr (P ? 0.06), a smaller pro-
portion was treated by TSS alone (P ? 0.09), and they had a
longer period of remission (P ? 0.0001). The SF-36 domain
of group 1 were not statistically different.

Postoperatively at the longest follow-up point (11.8 ? 4.9

these patients had low PCS (45.7 ? 0.7) and MCS (47.0 ? 0.7)
scores (mean ? sem; P ? 0.0001) compared with the general
population controls (50 ? 0.1). Corresponding z-scores for
PCS and MCS were ?0.4 ? 1.2 and ?0.3 ? 1.2.
Subjective health rating and satisfaction scale among cross-
Patients compared their current health to that before de-
veloping CS. Results from patients in the remission group
were as follows: much better, 38%; somewhat better, 12%;
about the same, 20%; somewhat worse, 20%; much worse,
7%; or missing, 3%. Similarly, when asked to rate their level
of satisfaction with the outcome of treatment for CS, re-
sponses were: extremely satisfied, 57%; quite satisfied, 26%;
moderately satisfied, 9%; slightly satisfied, 4%; not at all
satisfied, 2%; or missing, 3%.
HRQL by time from treatment
We observed long-term higher PCS (P ? 0.0001) and MCS
(P ? 0.01) scores in the cross-sectional analysis compared
with the pretreatment arm of group 1 (Fig. 3). There were no
significant changes in PCS or MCS scores in the posttreat-
ment period with increasing time from treatment (P ? 0.05).

Fatigue (41%), forgetfulness (35.7%), and trouble sleeping
(33.3%) were the most common symptoms. The presence of
any symptom was associated with lower PCS/MCS in all
cases in which a significant difference was observed. The
presence of symptoms measured using the total numerical
score of positive symptoms was inversely related to SF-36
summary domains: PCS: r ? ?0.5; P ? 0.0001; and MCS: r ?
?0.6; P ? 0.0001.
Effect of glucocorticoids
Although patients requiring glucocorticoids after remis-
sion of CS had marginally lower physical summary z-scores
(?0.5 ? 1.3 vs. ?0.3 ? 1.2; P ? 0.05), the remainder of the
SF-36 domains were similar (P ? 0.05) compared with those
who were glucocorticoid independent.
Predictors of HRQL
The use of glucocorticoids and previous pituitary XRT
were not significantly associated with impaired PCS and/or
MCS scores in a model that examined their relationship to
z-score deviation of more than 0.5 sd below age- and sex-
matched population means. Physical symptoms scores (de-
fined in Table 3) were significantly associated with both
PCS was 14.4 (6.4–32.7) and for MCS was 6.1 (2.9–12.8) in
those with six or more physical symptoms compared with
those with none or one symptom. Increasing time from treat-
ment was identified as a significant contributor to the ob-
ratios (95% CI) for impaired PCS was 0.4 (0.2–1.2), 0.36 (0.2–
0.9), and 0.3 (0.1–0.6) for patients 0–5, 5–10, and 10–15 yr
from treatment, respectively, compared with those who had
been treated more than 15 yr previously.

We examined differences in SF-36 responses for those in
apparent clinical remission compared with others who had
scores were lower among those who had a previous recur-
rence (37.6 ? 12.2), those with persistent hypercortisolism
(38.3 ? 3.7), and those who believed they were not cured
(34.2 ? 11.8) compared with the remission group detailed
above (by ANOVA, P ? 0.0001). Similarly, when we exam-
ined MCS scores, patients with a previous recurrence (41.9 ?
16.4), with persistent hypercortisolism (44.9 ? 3.7), or who
believed they were not cured (39.6 ? 13.3) had lower scores
than the remission group (P ? 0.0001).
The present series confirms that active CS is associated
with impaired HRQL. The magnitude of difference com-
pared with age- and sex-matched controls was large in all
SF-36 domains, except for mental health and bodily pain,
which were moderately impaired. The magnitude of these
changes also was similar to previous reports that HRQL in
active CS is significantly impaired compared with that in
subjects with acromegaly, prolactinoma, or nonfunctioning
