Case ReportsLong-term results of gamma knife surgery for growth hormone-producing pituitary adenoma: is the disease difficult to cure?
The authors conducted a study to determine the long-term results of gamma knife surgery for residual or recurrent growth hormine (GH)-producing pituitary adenomas and to compare the results with those after treatment of other pituitary adenomas. ⋯ Gamma knife surgery was effective and safe for the control of tumors; however, normalization of GH and IGF-1 secretion was difficult to achieve in cases with large tumors and low-dose radiation. Gamma knife radiosurgery is thus indicated for small tumors after surgery or medication therapy when a relatively high-dose radiation is required.

Long-term complications after gamma knife surgery for arteriovenous malformations.
The authors analyzed of the long-term complications that occur 2 or more years after gamma knife surgery (GKS) for intracranial arteriovenous malformations (AVMs). ⋯ Incomplete obliteration of the nidus is the most important factor associated with delayed hemorrhagic complications. Partial obliteration does not seem to reduce the risk of hemorrhage. Complete obliteration can be complicated by delayed cyst formation, especially if high maximal treatment doses have been administered.

Prolonged survival in a subgroup of patients with brain metastases treated by gamma knife surgery.
The authors analyzed the factors involved in determining prolonged survival (> or = 24 months) in patients with brain metastases treated by gamma knife surgery (GKS). ⋯ Aggressive local therapy with GKS, repeated GKS, and GKS plus surgery can achieve increased survival in a subgroup of patients with stable primary disease, no third-organ involvement, and long primary-brain secondary intervals.

Gamma knife surgery for cavernous hemangiomas: an analysis of 125 patients.
The authors sought to determine the value of gamma knife surgery (GKS) in the treatment of cavernous hemangiomas (CHs). ⋯ Gamma knife surgery can effectively reduce the rebleeding rate after the first symptomatic hemorrhage in patients with CH. In addition, GKS may be useful in reducing the severity of seizures in patients with CH.

A simple method for predicting imaging-based complications following gamma knife surgery for cerebral arteriovenous malformations.
The authors studied the relationship between dose planning parameters and complications in the treatment of cerebral arteriovenous malformations (AVMs). ⋯ The integral dose could be used as a guideline for the prescription dose. Arguments are made for maximizing the prescription dose for the long-term safety of the patient.
