Purpose/Objective:

1. Objectives: Pituitary adenomas are a benign histological tumour which primary treatment is surgery, often combined with medical therapy. Radiotherapy is indicated in non-operable patients and in case of residual disease or persistent hormonal hypersecretion after surgery.

The aim of this study is to evaluate the results in terms of hormonal, local control and safety data, of the patients treated with fractionated stereotactic radiotherapy (FSRT) in our centre.
