The experience observed after treating patients with obsessive-compulsive disorder (OCD), depression, and anorexia nervosa by Gamma Knife radiosurgery (GKRS) is presented. Ten patients with medically refractory OCD, 3 patients with depression resistant to medical treatment and electroconvulsive therapy, and 5 patients with refractory anorexia nervosa have been treated. Bilateral anterior capsulotomy has been performed to treat OCD and bilateral cingulotomy has been applied to treat severe depression and anorexia nervosa. The accumulated experience about treatment of OCD by GKRS is reviewed. In our experience, 70% of OCD patients achieved a full response. We observed a significant improvement in patients with depression and anorexia nervosa evidenced by the scales of assessment (mean reduction of 40% in the Beck Depression Inventory at 1-year follow-up and 40% average increase of body mass index at 6-month follow-up). No side effects have been observed. These procedures are effective in reducing obsession, compulsion, depression, and anxiety, improving the quality of life of the patients without side effects.</p>","PeriodicalId":39342,"journal":{"name":"Progress in neurological surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000493076","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37421301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While all three tumors are responsive to single-session radiosurgery, hemangiomas and hemangiopericytomas are the most likely to demonstrate tumor regression.

In the context of VHL, growing or recurrent tumors are treated with tumor control rates exceeding 90%. Tumor control improves with higher dose delivery, typically >15 Gy at the margin.

Patients who are refractory to medical management can explore surgical intervention. Deep-brain stimulation (DBS) and radiofrequency thalamotomy (RFT) are surgical procedures for intractable tremor that target the ventralis intermedius (VIM) nucleus to relieve contralateral tremor. For patients who are not candidates for surgical procedures, stereotactic radiosurgery (SRS) is a minimally invasive management option for tremor relief. SRS has been used for the elderly, those considered high surgical risk for other surgical procedures, those who are unresponsive to either DBS or RFT, and those who prefer a less invasive option. Radiosurgical thalamotomy is performed using a central dose of 130-140 Gy delivered to the VIM nucleus of the thalamus. The critical aspect of the dose planning procedure is the selection of the target, which requires a neurosurgeon experienced with movement disorder surgery. More than 90% of patients experience improvements in their tremor and quality of life after radiosurgical thalamotomy. Adverse radiation effects rates are low (4%). In selected cases, staged bilateral procedure can also be performed to relieve bilateral refractory tremor.

Often multimodal management is needed to achieve the best treatment outcome: tumor control coupled with endocrine, visual, and neurocognitive preservation. Many surgeons favor initial subtotal resection followed by adjunctive therapy to improve quality of life in a tumor with potentially long-term survival even if coupled with a need for periodic new interventions. During the patient's subsequent follow-up, solid or cystic tumor recurrence or progression often require additional management options. Leksell stereotactic radiosurgery (SRS) is a valuable adjuvant strategy that enhances long-term outcomes in patients with residual or recurrent craniopharyngiomas. Tumor control rates of 70-90% have been reported using 11- to 13-Gy tumor margin doses delivered using the Gamma Knife. Smaller tumors are associated with better radiosurgery outcomes. SRS is an effective management for residual or recurrent solid craniopharyngiomas with a favorable benefit-to-risk profile.</p>","PeriodicalId":39342,"journal":{"name":"Progress in neurological surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000493061","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37421299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
