Object The object of this study was to delineate long-term results of the surgical treatment of pediatric tumors classified as ganglioglioma or gangliocytoma. Methods A cohort of consecutive patients 19 years or younger who had undergone primary resection of CNS tumors during the years 1980-2016 at a single institution were reviewed in this retrospective study of surgical morbidity, mortality, and academic achievement and/or work participation. Gross motor function and activities of daily living were scored using the Barthel Index (BI). Results Patient records for 32 consecutive children and adolescents who had undergone resection for a ganglioglioma were included in this study. Of the 32 patients, 13 were in the first decade at the first surgery, whereas 19 were in the second decade. The male/female ratio was 1.0 (16/16). No patient was lost to follow-up. The tumor was localized to the supratentorial compartment in 26 patients, to the posterior fossa in 5 patients, and to the spinal cord in 1 patient. Only two of the tumors were classified as anaplastic. Of the 30 low-grade tumors, 2 were classified as gangliocytomas, 6 were desmoplastic infantile gangliogliomas, and 22 were ordinary gangliogliomas. The aim of primary surgery was gross-total resection (GTR) and was achieved in 23 patients (71.9%). Altogether, 43 tumor resections were performed. Eight patients underwent a second resection from 1 to 10 years after primary surgery and three of these also had a third resection from 2 to 24 years after initial surgery. The reason for further resection was clinical (seizure control failure/recurrence of epilepsy or progressive neurological deficit) and/or residual tumor progression/recurrence. There was no operative mortality in this series and all 32 patients are alive with follow-up periods from 0.5 to 36 years (median 14 years). Observed 14-year survival is thus 100%. One out of two children with primary anaplastic tumor received local radiotherapy (proton) postoperatively. The other 31 patients did not have any kind of non-surgical adjuvant therapy. Twenty-one out of 26 children with supratentorial tumor had epilepsy as one of their presenting symptoms. Nineteen of these became seizure-free after initial surgery (18 of them after GTR), but 3 patients experienced recurrence of seizures within some years. Functional outcome in terms of ADL, schooling, and work participation was gratifying in most patients. Five patients have persistent hydrocephalus (HC), treated with ventriculoperitoneal (VP) shunts. Conclusion Low-grade gangliogliomas (GGs) can be surgically treated with good long-term results including seizure and tumor control as well as school and working participation.
Long-term outcomes for low-grade intracranial ganglioglioma: 30-year experience from the Mayo Clinic
Journal of Neurosurgery, 2012
Object Gangliogliomas comprise less than 1% of all brain tumors and occur most often in children. Therefore, there are a limited number of patients and data involving the use or role of adjuvant therapy after subtotal resections (STRs) of gangliogliomas. The objective of this study was to examine and review the Mayo Clinic experience of 88 patients with gangliogliomas, their follow-up, risk of recurrence, and the role of radiation therapy after STR or only biopsy. Methods Eighty-eight patients with gangliogliomas diagnosed between 1970 and 2007 were reviewed. Data on clinical outcomes and therapy received were analyzed. The Kaplan-Meier method was used to estimate progression-free survival (PFS) and overall survival. Results The median age at diagnosis was 19 years. The median potential follow-up as of June 2008 was 142 months (range 9–416 months). Fifteen-year overall survival was 94%, median PFS was 5.6 years, with a 10-year PFS rate of 37%. Progression-free survival was dramatica...
Ganglioglioma: a clinical study with long-term follow-up
Surgical Neurology, 1991
Gangliogliomas are uncommon tumors of mixed neoplastic glial and neuronal elements. Because of their low incidence, few large series exist that fully describe the clinical characteristics of patients afflicted with this tumor. We have reviewed the medical records of 20 patients at Duke University Medical Center with histologically proven gangliogliomas. These patients typically presented within the first three decades of life and their most common presenting symptom was seizures. Therapies included surgical resection, either partial or total, radiation therapy, and/or chemotherapy. Long-term follow-up was achieved by chart review and by telephone interview. Patients who underwent gross total resection alone seemed to fare the best when comparing all treatment groups, and we therefore recommend this as the main form of treatment.
Ganglioglioma in a Survivor of Infantile Glioblastoma
Journal of Pediatric Hematology/Oncology, 2019
Congenital tumors account for 2% to 4% of all pediatric central nervous system tumors. Glioblastoma multiforme (GBM) represents a small subset of these tumors. Despite harboring histologic features similar to older patients, infants with GBM exhibit improved survival and respond more favorably to surgery and chemotherapy. To highlight this tumor's unique behavior, we report the case of a survivor of infantile GBM who developed a recurrent tumor in the surgical bed 6 months after diagnosis. The tumor was ultimately resected and was a ganglioglioma. This case shows both a favorable clinical outcome to an infantile GBM and this tumor's natural history.
Anaplastic ganglioglioma in children
Journal of Neuro-Oncology, 2008
Anaplastic gangliogliomas (AGG) are gangliogliomas with areas of pronounced hypercellularity, vascular proliferation, necrosis, and many mitotic figures. As very few pediatric patients have been studied, we analyzed the cases registered in the HIT-GBM database. Patients and Methods Patient data were obtained from the German HIT-GBM database. Inclusion criteria were diagnosis of AGG proven by a central neuropathological review and patient age 0 to 17 years. Eight patients (five male and three female) were identified. Results Patients' median age was 10 years. The median history of disease was 9 months (range, 1.0-43.0 months). Initial symptoms included signs of raised intracranial pressure, seizures, and, in the case of spinal cord tumor, bladder dysfunction. In five cases, AGGs were localized supratentorially with three patients having multiple lobes involved. The tumors affected the frontal (n = 3 cases), parietal (n = 2), temporal (n = 2), and occipital lobes (n = 1), as well as the brainstem (n = 1) and the spinal cord (n = 2). Gross total tumor resection was achieved in six patients. The estimated 5year overall survival rate ± standard error was 88 ± 12%, and the event-free survival rate was 63 ± 17%. While gender and tumor location did not affect survival rates, gross total tumor resection provided a better overall survival than non-total resection. Conclusion The prognosis of pediatric patients with AGG is good, especially for those who undergo gross total tumor resection.
Central nervous system gangliogliomas
Journal of Neurosurgery, 1993
The records of 58 patients with gangliogliomas surgically treated between January 1, 1980, and June 30, 1990, were retrospectively reviewed in order to determine long-term survival, event-free survival, and functional outcome resulting after radical resection and to assess the impact of histological grading on outcome. Tumors were located in the cerebral hemisphere in 19 cases, the spinal cord in 30, and the brain stem in nine. Forty-four patients had gross total resection and 14 had radical subtotal resection. Only six patients underwent postoperative irradiation or chemotherapy and, therefore, the outcome was generally related to surgery alone. Of the 58 gangliogliomas, 40 were classified as histological grade I, 16 were grade II, and two were grade III. The median follow-up period was 56 months. There were no operative deaths, and the operative morbidity rate was 5%, 37%, and 33% for cerebral hemisphere, spinal cord, and brain-stem gangliogliomas, respectively. The 5-year actuari...
Intracranial ganglioglioma: A rare case report
Gangliogliomas are considered rare tumors which account for 0.4-0.9% of intracranial neoplasms. The peak of its incidence occurs between 10 and 20 years of age. These tumors are composed of glial and ganglion cells and they are relatively low grade neoplasms associated with good prognosis. We report a rare case of intracranial ganglioglioma in a 10 year old boy who underwent surgery and adjuvant radiotherapy.
Gangliogliomas: pathological and clinical correlation
Journal of Neurosurgery, 1981
✓ Fourteen cases of ganglioglioma are analyzed. This tumor can be found anywhere within the central nervous system. The histological appearance is highly variable and does not relate to the biological behavior. The prognosis depends on the location and possible modes of treatment. Overall, the lesion appears to be nonaggressive and consistent with long survival.
Gangliogliomas: A report of five cases
Indian journal of cancer
Gangliogliomas are rare tumors of the Central Nervous System. Five gangliogliomas were diagnosed out of 1560 brain tumours surgically resected out in a period of 5 years accounting for 0. 32%. We have tried to discuss in detail the pathological features of these tumours and have mentioned the clinical and radiological features associated with them. All the slides, tissue blocks and pathology reports of the surgical specimens of gangliglioma were reviewed and the clinical and radiological data reviewed. The ages of the patients ranged from 7-65 years with 4 males and 1 female. The tumors were located in the lateral ventricle (a rare site), temporal, parietal and the frontal lobes with duration of seizures varying from 1-9 years. The tumors were diagnosed by the presence of a dual population of neoplastic ganglionic and glial components. The glial components consisted of pilocytic astrocytes (l case), fibrillary astrocytes (2 cases), oligodendrocytes (1 case) and anaplastic astrocytes...
Anaplastic ganglioglioma: a report of three cases and review of the literature
Journal of Neuro-Oncology, 2015
Gangliogliomas are rare tumors of the central nervous system that are thought to arise from a glioneuronal precursor and consist of both neuronal and glial elements. Grade III, or anaplastic ganglioglioma (AGG), most commonly affects children and young adults, generally arises in a supratentorial location, is highly epileptogenic, and often results in diffuse local and distant failure within the craniospinal axis. Pathologically, these tumors are graded by the degree of malignancy in their glial portion and radiologic diagnosis is difficult due to the wide variation in its degree of solid and cystic components, contrast uptake, and calcification patterns. This report presents three cases of AGG, with initial treatment including subtotal resection followed by conformal radiotherapy. In the case where the AGG developed in the setting of an existent low-grade astrocytoma, the patient received no chemotherapy. Both of the other de novo cases were managed with adjuvant chemoradiotherapy with temozolomide. Recurrence occurred at 6, 16, and 20 months following therapy. Two of the three patients experienced symptomatic decline at recurrence, but experienced Karnofsky performance status (KPS) improvement after salvage therapy, including the reduction of cranial neuropathy and balance. All patients had a significant reduction in presenting symptoms following salvage therapy. Patients died at 23, 20, and 22 months following initial surgical management, respectively. A review of anaplastic and malignant gangliogliomas is presented in the context of these three cases.
