Surgical experience with chromophobe adenomas of the pituitary gland

Abstract

✓ Between 1950 and 1969, 165 operations were performed on 146 patients for the treatment of chromophobe adenoma of the pituitary gland unassociated with either acromegaly or Cushing's syndrome. The over-all operative mortality was 1.2%, and no deaths occurred in 138 cases operated on for the first time. In 106 of the patients who had not received prior treatment, vision was improved in 80% of cases and returned to normal in 50%. In the group of patients whose initial treatment was surgery, postoperative radiation therapy was administered in one-half of the cases. The rate of recurrence was 8% in those who received radiation and 22% in those who did not. Recurrence of symptoms within less than 1 year often was due to a hemorrhagic cyst which could be treated better by reoperation than by radiation therapy.
