Abstract
Giant supratentorial brain tumors (GSBTs) in children are uncommon and extremely challenging entities unique to pediatric neurosurgery. Factors such as young patient age, need for urgent intervention, intraoperative blood loss, and ongoing raised intracranial pressure symptoms are examples of difficulties faced. Recently, there has been a growing body of literature on augmented reality (AR) in adult neurosurgery. In contrast, the use of AR in pediatric neurosurgery is comparatively less. Nonetheless, we postulate that AR systems will be helpful for understanding spatial relationships of complex GSBT anatomy for preoperative planning in a timely fashion. This study describes our experience in trialing AR as a potential tool for three cases of pediatric GSBTs. Overall, the AR platform offers our neurosurgical team excellent visuospatial insights for preoperative decision-making. However, we observe that substantial time is required to set up the AR system prior to each clinical case discussion by the neurosurgical team. In congruency with existing literature, our preliminary results report that there are still obstacles that need to be addressed before the technology can be seamlessly implemented into the clinical workflow for these time-sensitive childhood brain tumors. To our knowledge, this is the first study to report the potential use of AR for complex pediatric GSBT cases.

Abstract
PURPOSE To analyze the clinical character of giant pediatric supratentorial tumor (GPST) and explore prognostic factors. MATERIALS AND METHODS We analyzed the clinical data comprising of 35 cases of GPST from a single center between January 2015 and December 2020. The tumor volume was measured by 3D slicer software based on preoperative magnetic resonance imaging (MRI). Glasgow Outcome Scale (GOS) was used to evaluate the short-term prognosis. RESULT The tumor volume varied from 27.3 to 632.8 ml (mean volume 129.8 ml/ median volume 82.8 ml). Postoperative histopathological types include ependymoma, pilocytic astrocytoma, choroid plexus papilloma (CPP), craniopharyngioma, primitive neuroectoderm tumor (PNET), choroid plexus carcinoma (CPC), immature teratoma, atypical teratoid rhabdoid tumor (AT/RT), anaplastic astrocytoma, and gangliocytoma. Tumors in children younger than 3 years and tumors located at the hemispheres appeared to be larger than their respective counterparts, though no statistical significance was found. A patient with giant immature teratoma died during the operation because of excessive bleeding. Postoperative complications include cerebrospinal fluid subgaleal collection/effusion, infection, neurological deficits, and seizures. The mean GOS score of patients with GPST in 6 months is 3.43 ± 1.12, and 83% of patients (29/35) showed improvement. Favorable GPST characteristics to indicated better GOS included small tumor (≤100 ml) (p = 0.029), low-grade (WHO I-II) (p = 0.001), and gross total resection (GTR) (p = 0.015). WHO grade was highly correlated with GOS score (correlation coefficient = -0.625, p < 0.001). GTR and tumor volume were also correlated (correlation coefficient = -0.428, p = 0.010). CONCLUSION The prognosis of GPST is highly correlated with the histopathological type. Smaller tumors are more likely to achieve GTR and might lead to a higher GOS score. Early diagnosis and GTR of the tumor are important for GPST management.

Abstract
Abstract
Background
Brain tumors in the first years of life are frequently encountered recently with the advancement in neuroimaging, neurosurgery and neuroanethesia where early diagnosis of these lesions became available even before birth. Their management is challenging where the surgery is technically demanding, radiotherapy is omitted in this age because of its late sequelae and chemotherapy role may be beneficial, but it is limited also by its side effects and neurotoxicity. The aim of this article is to review the current literature about the brain tumors in the first two years of life, their diagnosis and treatment.
Main body
Brain tumors in the first two years of life encompass mainly fetal/congenital tumors and infantile tumors. They account for 1.4–18% of cases of pediatric brain tumor, and most of them are diagnosed in the first year of life. The main histopathologies diagnosed are glial tumors, choroid plexus tumors, medulloblastoma and other embryonal tumors, teratoma and ependymoma. They are mainly supratentorial. Large head and bulging fontanelles are the main presenting symptoms and signs secondary to increased intracranial pressure secondary to large tumors or associated hydrocephalus. Prenatal and postnatal ultrasonography represents the initial imaging step in the diagnosis that should be complemented by MRI and CT brain. The main and first line of treatment of infantile brain tumors is surgical excision as the prognosis is directly related to the extent of resection besides surgery offers specimens for histopathological diagnosis and adjuvant chemotherapy is given for residual irresectable cases and malignant tumors with the main aim to delay radiotherapy beyond the age of three years.
Conclusion
Brain tumors in the first two years of life are a challenging group of different histopathological entities with underlying specific molecular characterization and genetic predispositions. They have aggressive behavior and general poor prognosis with limited options of management. Individualized multidisciplinary management for each case is needed, and future studies for therapeutic medications targeting underlying molecular biology may improve their outcome.

Feasibility of Proton Beam Therapy for Infants with Brain Tumours: Experiences from the Prospective KiProReg Registry Study. Clin Oncol (R Coll Radiol) 2021; 33:e295-e304. [PMID: 33820696 DOI: 10.1016/j.clon.2021.03.006] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2020] [Revised: 01/16/2021] [Accepted: 03/09/2021] [Indexed: 11/22/2022]
Abstract
AIMS Proton beam therapy (PBT) has increasingly been applied for the treatment of young children when radiotherapy is needed. The treatment requires intensive multimodality care and is logistically demanding. In this analysis, we evaluated our experiences in treating infants with tumours of the central nervous system with PBT. MATERIALS AND METHODS Children younger than 2 years of age treated with PBT for central nervous system tumours enrolled in the prospective registry study KiProReg were retrospectively analysed. Information on patient characteristics, treatment, toxicities and outcome were evaluated. Adverse events were classified according to the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE V4.0) before, during and after PBT. RESULTS Between September 2013 and June 2018, 51 infants were eligible. The median age was 19 months (range 11-23 months) at the time of PBT. Tumour entities were ependymoma (51.0%), atypical teratoid rhabdoid tumour (39.0%), high-grade glioma (6.0%), pineoblastoma (2.0%) and medulloblastoma (2.0%). The prescribed median total dose was 54.0 Gy (range 45.0-59.4 Gy). Most received local radiotherapy. In four patients, craniospinal irradiation followed by a boost to the local tumour bed was applied. The median follow-up time was 42.0 months (range 7.3-86.2 months). The estimated 3-year local control, progression-free survival and overall survival rates for all patients were 62.7, 47.1 and 76.5%, respectively. During radiotherapy, 24 events of higher-grade (CTCAE ≥ °III) toxicities were reported. Interruption of radiotherapy for more than 2 days was due to infection (n = 3) or shunt complication (n = 2). Unexpected hospitalisation during radiotherapy affected 12 patients. Late adverse events attributable to radiotherapy included endocrinopathy (CTCAE °II; 7.8%), new onset of hearing loss (CTCAE °III; 5.8%) and visual impairment (CTCAE °IV; 1.9%). Transient radiation-induced imaging changes occurred in five patients (9.8%). CONCLUSIONS Our study indicates that PBT is feasible for very young children with central nervous system tumours, at least in the short term. However, it requires challenging interdisciplinary medical care and high logistical effort. For evaluation of late effects, longer follow-up and evaluation of neurocognitive outcome are desirable. More data have to be gathered to further define the role of radiotherapy in infants over time.

Pediatric central nervous system tumors in the first 3 years of life: pre-operative mean platelet volume, neutrophil/lymphocyte count ratio, and white blood cell count correlate with the presence of a central nervous system tumor. Childs Nerv Syst 2017; 33:233-238. [PMID: 27942922 DOI: 10.1007/s00381-016-3301-1] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2016] [Accepted: 11/15/2016] [Indexed: 10/20/2022]
Abstract
PURPOSE The aim of this study is to describe the relationship of pre-operative complete blood count parameters [mean platelet volume (MPV), neutrophil/lymphocyte count ratio (NLCR), and white blood cell count (WBC)], with the clinical, radiological, and histopathological features and the management options for patients under 3 years of age with a newly diagnosed central nervous system tumors. METHODS Children with central nervous system (CNS) tumors in the first 3 years of life admitted in the Erciyes University Hospital between April 2004 and April 2014 were enrolled in this study. The CBC parameters were compared with those of an age- and sex-matched normal control group. RESULTS In the study group, the means of MPV and WBC were 8.00 ± 1.24 fl, and 10,855 ± 3642/mm3 respectively; the median (25-75%) of NLCR was 0.98 (0.66-1.46). For the control group, the means of MPV and WBC were 6.8 ± 0.73 fl and 8565 ± 2522/mm3; the median (25-75%) of NLCR was 0.52 (0.36-0.70). The MPV, WBC, and NLCR were higher in the study group. The median overall survival (OS) of the patients was 60 months (range 0-81.6 months); and median event free survival (EFS) was 24 months (range 0-70.1 months). The formulation of MPV, NLCR, and WBC was found to be predictive for the diagnosis of CNS tumor in children with nonspecific symptoms. The univariate and multiple binary regression analyses showed a positive association of MPV, NLCR, and WBC and the risk of a diagnosis of CNS tumor. There was no relationship between MPV, WBC, NLCR, and histological subgroups. However, there were no associations between CBC parameters and OS or EFS of the patients. CONCLUSIONS By causing suspicion, MPV, NLCR, and WBC may provide both an earlier radiological investigation decision and thereby an early diagnosis of CNS tumor in children with nonspecific symptoms in the first 3 years of life.

Abstract
OBJECTIVE The survival rate and prognosis in infants with giant intracranial tumors are significantly worse than in older children. This study aimed to analyze the feasibility of delayed operation for infants with giant intracranial benign tumor by evaluating the initial clinical presentations, expectant treatment measures, perioperative vital signs, and recuperation after surgery. PATIENTS AND DATA We reviewed 3 infant patients (average age, 9.33 months; range, 5-12 months) with giant intracranial benign tumors during January 2015 and April 2016. The maximum sections of tumors were 38 × 50 mm, 57 × 39 mm, and 55 × 67 mm, respectively. All clinical presentations, neuroimaging, and laboratory examinations were recorded. RESULTS Obstructive hydrocephalus was observed in 2 infants; ventriculoperitoneal shunts were placed in both before the delayed tumor resection. The disease progressed rapidly in the infant with teratoma and surgery was performed 4 months after placement of the ventriculoperitoneal shunt. The other 2 patients had experienced a 12-month growth and developmental phase and later underwent operations. Gross total resection was achieved in all patients. The pathologic results were consistent with the preoperative diagnosis. During a period of high-quality postoperative care, they remained stable and were discharged without any complications or neurologic deficits, and continued to improve toward their baseline. CONCLUSIONS Delayed operation enabled infant patients to gain a better physical state, with a stage of full preoperative preparation that may reduce intraoperative/postoperative morbidity and mortality.

Abstract
OBJECTIVE This study aims to evaluate the impact of gross total resection of giant supratentorial brain tumors (GSBT) on survival and neurological outcome in a consecutive single-center pediatric series. METHODS Clinical data of 23 patients under 18 years of age operated with GSBT (≥5 cm in diameter) were reviewed to determine epidemiological aspects, clinical presentation, associated factors, histopathological features, and outcome. Volumetric measurements were performed on magnetic resonance imaging or computed tomography scans obtained at the time of the initial surgical procedure. RESULTS The group included 23 patients (mean age 4.5 years). Signs and symptoms of raised intracranial pressure were present in 19 patients (82.6%). The most frequent tumor location was the parietal lobe in 19 patients (82.6%), and the mean tumor volume was 208 cm(3). Gross total or radical resection was achieved in all patients. Histopathological analysis revealed malignant brain tumors in 18 cases (78.2%). The most common neoplasm was choroid plexus carcinoma in seven (30.4 %). Mean intraoperative blood transfusion volume was 51.2 ml/kg. Chemotherapy and/or radiotherapy were performed as adjuvant treatment in 16 patients (69.5%). Mean length of follow-up was 36.7 months. Tumor malignancy grade significantly correlated with recurrence of the disease (P = 0.03) and death (P = 0.01), as opposed to tumor location, size, and extension to the ventricles. CONCLUSIONS Our clinical experience suggests that tumor mass reduction by en bloc surgery seems to be an effective approach in pediatric patients with GSBT, relieving symptoms related to raised intracranial pressure and providing a better response to adjuvant treatment.

Abstract
OBJECT Ependymoma is the third most common primary brain tumor in children. Tumors are classified according to the WHO pathological grading system. Prior studies have shown high levels of variability in patient outcomes within and across pathological grades. The authors reviewed the results from the published literature on intracranial ependymomas in children to describe clinical outcomes as they relate to treatment modality, associated mortality, and associated progression-free survival (PFS). METHODS A search of English language peer-reviewed articles describing patients 18 years of age or younger with intracranial ependymomas yielded data on 182 patients. These patients had undergone treatment for ependymoma with 1 of 5 modalities: 1) gross-total resection (GTR), 2) GTR as well as external beam radiation therapy (EBRT), 3) subtotal resection (STR), 4) STR as well as EBRT, or 5) radiosurgery. Mortality and outcome data were analyzed for time to tumor progression in patients treated with 1 of these 5 treatment modalities. RESULTS Of these 182 patients, 69% had supratentorial ependymomas and 31% presented with infratentorial lesions. Regardless of tumor location or pathological grade, STR was associated with the highest rates of mortality. In contrast, GTR was associated with the lowest rates of mortality, the best overall survival, and the longest PFS. Children with WHO Grade II ependymomas had lower mortality rates when treated more aggressively with GTR. However, patients with WHO Grade III tumors had slightly better survival outcomes after a less aggressive surgical debulking (STR+EBRT) when compared with GTR. CONCLUSIONS Mortality, PFS, and overall survival vary in pediatric patients with intracranial ependymomas. Pathological classification, tumor location, and method of treatment play a role in outcomes. In this study, GTR was associated with the best overall and PFS rates. Patients with WHO Grade II tumors had better overall survival after GTR+EBRT and better PFS after GTR alone. Patients with WHO Grade III tumors had better overall survival after STR+EBRT. Patients with infratentorial tumors had improved overall survival compared with those with supratentorial tumors. Progression-free survival was best in those patients with infratentorial tumors following STR+EBRT. Consideration of all of these factors is important when counseling families on treatment options.

Abstract
Desmoplastic gangliogliomas (DIG) are rare primary neoplasms that comprise 0.5-1.0% of all intracranial tumors. Clinically, there are two forms of DIG, the infantile and the non-infantile. These tumors invariably arise in the supratentorial region and commonly involve more than one lobe, preferentially the temporal and frontal. On neuroimaging are seen as large hypodense cystic masses with a solid isodense or slightly hyperdense superficial portion. The histologic diagnosis is characterized by the presence of three different cell lines: astrocytic, neuronal, and primitive neuroectodermal marker sites, which were demonstrable. The treatment of choice is radical surgical excision, and if this is done, achieved complete healing of the patient does not require additional treatment. A literature review of DIG was compiled through Medline/Ovid using the keywords "desmoplastic infantile ganglioglioma", "desmoplastic non-infantile ganglioglioma" covering the years 1984-2009. We present a review of a total of 113 cases of infantile (94) and non-infantile gangliogliomas (19) published to date, examining the clinical, radiologic, surgical, and pathological aspects, as well as the outcome. Desmoplastic gangliogliomas represent a rare tumor group with two well-defined age groups, the children and non-children. Desmoplastic infantile gangliogliomas are the most common and occur in children below 5 years of age, and the large majority of them present within the first year of life. Surgery is the treatment of choice and no complementary treatment is needed in cases of complete tumor resection.
