The survival and well-being of patients treated for Cushing's syndrome.
OBJECTIVE
The main aim of the study was to evaluate the survival, well-being and working capacity of patients treated for Cushing's syndrome.


METHODS
The study was carried out by retrospectively analysing patient records from years 1981-94. Follow-up time was extended from the time of diagnosis to the end of 1996. A questionnaire dealing with symptoms prior to and after therapy, and the quality of life estimated on a Visual Analogue Scale (VAS) was sent to all surviving patients.


METHODS
The study was performed in a university hospital.


METHODS
Survival, subjective well-being, working capacity before and after treatment and disappearance of symptoms after treatment of Cushing's syndrome.


RESULTS
During the follow-up time 10 patients died out of a total of 74. The overall standardized mortality ratio (SMR) was 168% (95% CI 81-309%). The SMR of patients with pituitary disease was 267% (89-525%), and in patients with adrenal adenoma it was 135% (16-489%). Forty-six per cent of the surviving patients stated that they felt fully recovered from the disease, but the proportion of patients having persisting symptoms after treatment was also noteworthy. The mean VAS score (range 0-100) was 19 (SD 14) before treatment and 82 (SD 18) after treatment (P<0.001). After treatment, 81% of the patients were able to return to work, 11% retired because of disability, 5% retired because of age and 3% were on sick-leave at the time of answering the questionnaire. During the follow-up time, 42% of the patients with pituitary disease suffered a relapse. However, the effect of the relapse on well-being was not significant.


CONCLUSIONS
The mortality risk of patients treated for Cushing's disease was not significantly increased compared with that of the general population. Many symptoms persisted even years after therapy. After clinical recovery, working ability was not always regained.
