The preoperative outlook and surgical results are evaluated in 29 acromegalic patients, employing the usual serum growth hormone (GH) screening techniques in association with GH response to the thyrotropin releasing hormone (TRH) test. Results obtained by transphenoidal microsurgical technique in adenomas of different size and sellar morphology are reported. Overall results clearly favor selective microsurgery in early diagnosed and operated tumors (microadenomas), while a less than radical approach does not hold much promise of functional normalization in larger adenomas. In nonnormalized cases the efficacy of radiotherapy is stressed. The TRH test results were a good indication for radiation therapy even in those cases in which GH normalized after surgery by common assay methods.
