Nonfunctioning pituitary adenoma: incidence, causes of death and quality of life in relation to pituitary function.
The incidence of clinically significant, nonfunctioning pituitary adenoma, requiring surgical treatment, has not been established. According to previous studies, both surgery type and subsequent radiotherapy may have an impact on quality of life (QOL), and some studies have shown increased cardiovascular mortality in patients with pituitary disease. We studied all patients with functionless, suprasellar pituitary adenoma who were operated on during the period 1985-1996 (N = 192; transsphenoidal surgery = 160, craniotomy = 32). QOL was evaluated from Short Form 36 and Major Depression Inventory questionnaires. Causes of death were obtained from the Danish Register of Causes of Death. Incidence was 5.6/mill/year. Postoperatively, 27% of the patients had normal pituitary function and 27% were panhypopituitary. Fifty three patients had died. Death from cardiovascular, cerebrovascular and malignant diseases was not increased. Overall, QOL was not different from QOL of an age- and sex matched background population. QOL was, however, impaired in patients who had undergone craniotomy as compared to patients undergoing transsphenoidal surgery. QOL was not reduced in hypopituitary patients or in patients receiving radiotherapy.
