Three major therapeutic modalities (transsphenoidal surgery, radiotherapy and medical therapy) are currently available for acromegaly. Although surgery is regarded as the primary option, 50--60% of macroadenomas require further treatment in the form of radiotherapy and/or medical therapy. Recent studies have suggested that radiotherapy might damage the normal hypothalamic-pituitary axis and also rarely leads to IGF-I normalization. The aims of this study were: (1) to examine the effect of different therapeutic modalities (transsphenoidal surgery, TSS; radiotherapy, RT; medical treatment with somatostatin analogues, SSA) on the daily spontaneous GH secretory pattern (day curve); and (2) to determine the relationship between the characteristics of the GH secretory pattern and the circulating concentration of IGF-I, acid-labile subunit (ALS) and IGFBP-3.
