Intracranial ganglioglioma WHO I: results in a series of eight patients treated with stereotactic interstitial brachytherapy.
In this retrospective study we evaluated the efficacy of interstitial brachytherapy (IBT) using (125)Iodine seeds ((125)I) for intracranial ganglioglioma WHO I. Between October 1994 and March 2010, eight patients (m/f = 5/3, median age 30.4 years, age range 7-42.5 years) with intracranial ganglioglioma WHO I were treated with IBT using stereotactically implanted (125)I seeds. The median follow-up time was 41.5 months (range 16.7-140.1 months). Prior to interstitial brachytherapy one patient underwent microsurgical resection for three times; seven patients were treated with IBT primarily. In all patients we implanted the (125)I seeds stereotactically guided. The cumulative tumor surface dose ranged between 50 and 65 Gy (permanent implantation) and the median tumor volume was 5.6 ml (range 0.9-26 ml). After brachytherapy, follow-up MR imaging revealed complete remission in one patient, partial remission in three and stable disease in the remaining four patients. Five of eight patients presented with seizures were either seizure-free (1/5) or improved (4/5). Temporary treatment-related morbidity occurred in one patient only (headache, nausea/vomiting) and resolved completely under steroid medication after 4 weeks. No treatment-related mortality was observed. This study indicates that interstitial brachytherapy for the treatment of intracranial ganglioglioma WHO I is safe and provides a high rate of local tumor control. Due to the limited number of cases, it is not possible to conduct a rigorous statistical evaluation. Thus, larger numbers of patients are required.
