Brief Summary
In this study, the investigators hypothesize that upfront gamma knife radiosurgery with drug therapy is superior in the treatment of growth hormone-secreting pituitary tumors after primary surgical treatment compared with the drug therapy alone. This study can provide useful clinical information in the treatment of patients with acromegaly.

Outcome Measures
Primary Outcomes (1)
endocrinologic remission
Achieving random growth hormone level below 2.5 ug/L and normalization of insulin-growth factor-1 level
at 2 year after initial enrollment
Secondary Outcomes (4)
tumor size
1 year interval
drug requirement dosage
at 3 months after initial enrollment and 6 months thereafter for 2 years
side effect
at 3 months after initial enrollment and 6 months thereafter for 2 years
performance status
at 3 months after initial enrollment and 6 months thereafter for 2 years
Study Arms (2)
intervention
EXPERIMENTALGamma knife radiosurgery (Leksell Gamma Knife, Elekta AB, Stockholm, Sweden) is used for intervention. Administration of standard medical therapy using Lanreotide 60 mg concurrently starts with radiosurgery
control
ACTIVE COMPARATORWithout radiosurgery, standard medical therapy (Lanreotide 60Mg Solution for Injection) same with interventional group is applied
Interventions
Minimum 25 Gy of marginal dose is applied for residual tumor or resection cavity. Depending on the size of tumor, the dose can be varied.
Eligibility Criteria
You may qualify if:
- Among patients with acromegaly due to growth hormone secreting pituitary adenoma who underwent primary surgical resection, patients who fail to achieve endocrinologic remission at 3 months after surgery.
- On brain MRI scan at 3months after surgery, residual tumor is confirmed by clinicians
- the definition of endocrinologic remission
- random growth hormone level \< 2.5 ug/L
- normalization of age-matched insulin growth factor-1 level
You may not qualify if:
- patients with contraindication of stereotactic radiosurgery; e.g. pregnancy or planning pregnancy, or claustrophobia
- recurrent pituitary adenoma
- limited life expectancy due to systemic disease; e.g. malignant tumor, genetic disease, and terminal stage of renal or hepatic failure
- disability to clinic visit due to postoperative complications

- Masking Details
- Technically, the procedure of gamma knife radiosurgery includes fixating stereotactic frame on the head of patients. Therefore, It is not possible to keep masking for participants and other investigators.
