Background: Our study evaluated the perioperative quality of life (QoL) in Cushing’s disease (CD) patients, along with correlations between patient variables and cure rate. Methods: The 36-item Short-Form Health Survey (SF)-36 questionnaire was used to assess perioperative QoL. Patients completed one survey preoperatively and two surveys postoperatively. Retrospective chart review was conducted to collect SF-36 data as well as examine variables including: age, hospital stay, size of tumour, pathological diagnosis, timing of cure, and complication rates. Statistical analysis was conducted on the scores reported by the SF-36, and were compared with the normal Canadian population values, and to a sample of QoL from nonfunctioning pituitary tumour patients. This project was approved by University of British Columbia Research Ethics Board #H15-01572. Results: In general, CD patients have relatively poor QoL that does improve as expected when cured, but not quite to normal levels. Factors associated with cure included presence of macroadenoma, confirmatory pathology, and patient age. Postoperative timing of cure appears to affect the durability of cure, with an immediate cure having a higher durability rate than delayed cure. Most recurrences occurred within 10 months postoperatively. Conclusions: This review of the perioperative QoL in CD helps to illustrate how QoL changes throughout the treatment process, how QoL compares to normal Canadian population levels, and how QoL compares to patients with nonfunctioning pituitary adenomas. As treatment outcome has such a high impact on QoL, the variables identified in this study will help to better inform patients about the treatment course.

Background: Sellar masses (SM) are mostly benign growths of pituitary or nonpituitary origin that are increasingly encountered in clinical practice. To date, no comprehensive population-based study has reported the epidemiology of SM from North America. Aim: To determine the epidemiology of SM in the province of Nova Scotia, Canada. Methods: Data from all pituitary-related referrals within the province were prospectively collected in interlinked computerized registries starting in November 2005. We conducted a retrospective analysis on all patients with SM seen within the province between November 2005 and December 2013. Results: A total of 1107 patients were identified, of which 1005 were alive and residing within the province. The mean age at presentation was 44.6±18 years, with an overall female preponderance (62%) and a population prevalence rate of 0.1%. Of patients with SM, 837 (83%) had pituitary adenomas and 168 (17%) had nonpituitary lesions. The relative prevalence and standardized incidence ratio, respectively, of various SM were: nonfunctioning adenomas (38.4%; 2.34), prolactinomas (34.3%; 2.22), Rathke’s cyst (6.5%; 0.5), growth hormone–secreting adenomas (6.5%; 0.3), craniopharyngiomas (4.5%; 0.2), adrenocorticotropic hormone–secreting adenomas (3.8%; 0.2), meningiomas (1.9%), and others (3.9%; 0.21). At presentation, 526 (52.3%) had masses ≥1 cm, 318 (31.6%) at <1 cm, and 11 (1.1%) had functioning pituitary adenomas without discernible tumor, whereas tumor size data were unavailable in 150 (14.9%) patients. The specific pathologies and their most common presenting features were: nonfunctioning adenoma (incidental, headaches, and vision loss), prolactinomas (galactorrhea, menstrual irregularity, and headache), growth hormone–secreting adenomas (enlarging extremities and sweating), adrenocorticotropic hormone-secreting adenoma (easy bruising, muscle wasting, and weight gain) and nonpituitary lesions (incidental, headaches, and vision problems). Secondary hormonal deficiencies were common, ranging from 19.6% to 65.7%; secondary hypogonadism, hypothyroidism, and growth hormone deficiencies constituted the majority of these abnormalities. Conclusions: This is the largest North American study to date to assess the epidemiology of SM in a large stable population. Given their significant prevalence in the general population, more studies are needed to evaluate the natural history of these masses and to help allocate appropriate resources for their management.
