TY - JOUR ID - TI - Outcomes of Gamma Knife Surgery in the Treatment of Patients with Metastatic Brain Tumors AU - Abdulameer Jasim Al-Khafaji*, Hayder Ali Al-Saadi** PY - 2019 VL - 18 IS - 1 SP - 1 EP - 9 JO - Iraqi Postgraduate Medical Journal المجلة العراقية للاختصاصات الطبية SN - 83601608 98932708 AB - BACKGROUND:Cerebral metastases are by far the most common intracranial tumors in adults. gamma kniferadiosurgery has arguably been the most important advancement in the management of metastaticbrain tumors since the 1980s.OBJECTIVE:To evaluate the effectiveness of gamma knife radiosurgery as a treatment of metastatic braintumors.METHODS:This is a prospective study (the first trial in Iraq) of 27 patients (42 tumors) of brain metastasisbetween March 2016 and October 2017. Imaging follow up done in 6 months and 12 months,clinical follow up done in 3 weeks and 3 months.RESULTS:In the first six months 81.0% of the MBTs were regressed or remain stable in size. After 3months post GKS, 81.5% patients showed neurological improvement. 82.4% of the patients<65years old survive for 12 months and 85% of patients with KPS>70 survive for 12 months.CONCLUSION:The routine blood investigations, the gender and the location were of no significance on patients’general outcome or the tumor/edema response to gamma knife. Presence of extracranialmetastasis, single or multiple MBTs found to have important effect on patients’ survival.
