Quality of Life in Patients with a Pituitary Adenoma

A validated quality of life (QOL) measure, the SF-36 questionnaire, was used to assess patients' perception of the impact of a pituitary adenoma, prior to treatment, on his or her physical and mental functioning. Of 270 new patients evaluated for pituitary disease at the University of Virginia Pituitary Clinic, 168 met the criteria for inclusion (pituitary hormone hypersecretion and/or pituitary adenoma) into this prospective study. Results of the SF-26 questionnaire in 36 patients with acromegaly, 42 patients with Cushing's disease, 39 patients with a prolactinoma and 51 patients with a non functioning macroadenoma prior to treatment were compared with those of the normal population; a comparison of results among patients with different types of pituitary adenomas was also performed. Patients with a pituitary adenoma had a significantly decreased QOL compared with the normal population in both physical and mental measures (p < 0.05). There were different degrees of perceived impairment depending on the type of pituitary adenoma. Patients with acromegaly had impairment in measures of physical function while patient with Cushing's disease had impairment in all but one measures compared with the normal population and with patients with other types of pituitary adenomas. Patients with a prolactinoma had impairment in mental measures and patients with a non-functioning adenoma had impairment in both physical and mental measures compared with the normal population. Patients with a pituitary adenoma have an impaired quality of life that should be routinely assessed in conjunction with endocrine and anatomic studies before and after treatment.
