INTRODUCTION: It was reported that proton beam therapy (PBT) reduced the normal brain dose compared with X-ray therapy for pediatric brain tumors. We considered whether there was not the condition that PBT was more disadvantageous than intensity modulated photon radiotherapy (IMRT) and 3D conventional radiotherapy (3D-CRT) for treatment of pediatric brain tumors about the dose reduction for the normal brain when the tumor location or tumor size were different. METHODS: The subjects were 12 patients treated with PBT at our institute, including 6 cases of ependymoma treated by local irradiation and 6 cases of germinoma treated by irradiation of all four cerebral ventricles...

Central neurocytomas are slow-growing primary brain tumors of neuronal origin having a predilection to arise mostly in the lateral ventricles. We report a case of a 9-year-old girl who presented with headache and vomiting of 1-month duration. Her magnetic resonance imaging was suggestive of central neurocytoma of the third ventricle and was surgically managed, and tumor tissue was sent for histopathology and immunohistochemistry which confirmed the diagnosis.

Ependymoma tends to occur commonly along either on ventricular surfaces of the brain or central canal of the spinal cord. Rarely, ependymoma can develop in the cerebral cortex without attachment to the ventricular structures. However, such occurrence in the purely extra-axial compartment in the falcine region mimicking falcine meningioma is exceedingly rare. The detailed search of primary falcine ependymoma (PEFE) in Medline and PubMed yielded only five isolated case reports. All cases occurred in patient older than 17 years of age; however, our case was a 9-year-old girl...

BACKGROUND: The molecular diagnosis of brain tumors is important in classifying tumors and determining appropriate treatment. Congenital glioblastoma multiforme (GBM) is a rare tumor that occurs in infants, and the prognosis is poor. Approximately 60 patients diagnosed as congenital GBM have been reported. However, few reports have conducted molecular analyses of congenital GBM. CASE DESCRIPTION: We describe two congenital GBM patients treated in our hospital, and report results of immunohistochemistry, fluorescent in situ hybridization (FISH), direct sequencing, and methylation analyses...

Medulloblastoma is the most frequent malignant pediatric brain tumor and is divided into at least four subgroups known as WNT, SHH, Group 3, and Group 4. Here, we characterized gene regulation mechanisms in the most aggressive subtype, Group 3 tumors, through genome-wide chromatin and expression profiling. Our results show that most active distal sites in these tumors are occupied by the transcription factor OTX2. Highly active OTX2-bound enhancers are often arranged as clusters of adjacent peaks and are also bound by the transcription factor NEUROD1...

Medulloblastoma is a highly aggressive pediatric brain tumor, in which sporadic expression of the pluripotency factor OCT4 has been recently correlated with poor patient survival. However the contribution of specific OCT4 isoforms to tumor aggressiveness is still poorly understood. Here, we report that medulloblastoma cells stably overexpressing the OCT4A isoform displayed enhanced clonogenic, tumorsphere generation, and invasion capabilities. Moreover, in an orthotopic metastatic model of medulloblastoma, OCT4A overexpressing cells generated more developed, aggressive and infiltrative tumors, with tumor-bearing mice attaining advanced metastatic disease and shorter survival rates...

PURPOSE: Giant pediatric intracranial tumor (GPIT) remains to be a challenging disease with high morbidity and mortality. METHODS: The clinical data of 60 patients under 18 years of age operated on with GPIT (≥5 cm in diameter) were retrospectively analyzed. RESULTS: Gross total resection was achieved in 46 cases (77%) and subtotal resection was obtained in 14 cases (23%). Ninety percent (47/52) of the cases with obstructive hydrocephalus were resolved remarkably and only 10% (5/52) of the patients needed a ventriculoperitoneal shunt after tumor resection...

Central nervous system (CNS) tumors represent the second most prevalent group of cancers in children and adolescents, yet account for the majority of childhood cancer-related deaths and considerable morbidity among survivors, due to high-intensity non-selective standard therapies delivered to immature nervous system structures undergoing development. These tumors arise at different ages -not infrequently very early in life-, in different locations and cellular contexts, have varied cell types of origin, and have heterogeneous responses to the "classic" current therapeutic approaches...

In adolescent and young adult(AYA)population, cancer is the leading cause of death due to illness with the lowest mortality rate as well as children, and national measures for cancer was left behind. Leukemia, lymphomas, brain tumors, thyroid cancer, ovarian cancer, cervical cancer, breast cancer, testicular cancer and bone and soft tissue sarcomas account for majority of the cancers in this age group. There has been no significant improvement in AYA patients in contrast to other age groups. AYA patients with cancer are under growing independency, starting in life to the community, and reproductive age...

: 151 Background: Early phase clinical trials are critical to enhancing therapies for children with advanced cancer. However, trial enrollment may intensify end-of-life (EOL) care. We evaluated patterns of EOL care for patients at a large cancer center. METHODS: Single-center, retrospective cohort study of pediatric oncology patients, ages 6 months-21 years, who died in 2010-2014. We queried electronic medical records to assess frequencies of medical procedures (e...

Brain tumors are the leading cause of cancer-related death in children but high-grade gliomas in children and adolescents have remained a relatively under-investigated disease despite this. A better understanding of the cellular and molecular pathogenesis of the diseases is required in order to improve the outcome for these children. In vitro-cultured primary tumor cells from patients are indispensable tools for this purpose by enabling functional analyses and development of new therapies. However, relevant well-characterized in vitro cultures from pediatric gliomas cultured under serum-free conditions have been lacking...

BACKGROUND: Pilocytic astrocytomas (PAs) are the most common pediatric central nervous system neoplasms. In the majority of cases these tumors are benign and receive favorable prognosis following gross total surgical resection. In patients with progressive or symptomatic tumors, aggressive surgical resection is generally not feasible, thus radiation or chemotherapy are accepted initial or adjuvant interventions. Due to serious long-lasting side-effects, radiation is limited in young children; therefore, chemotherapy is widely practiced as an adjuvant treatment for these patients...

Children are at increased risk for cognitive difficulties following the diagnosis and treatment of a brain tumor. Radiation therapy (RT) and tumor location are commonly-cited predictors of neurocognitive functioning. Disruptions to foundational neurocognitive processes such as attention, working memory, and processing speed underlie declines on measures of general intellectual functioning. While several studies have examined visual sustained attention in pediatric brain tumor patients, auditory sustained attention has yet to be examined...

The ETV6-NTRK3 translocation characterizes a subset of radiation associated and pediatric papillary thyroid carcinomas (PTCs). We now describe the clinicopathologic features of ETV6-NTRK3 translocated PTC in an adult population without radiation exposure. Twelve cases were identified by next-generation sequencing (ThyroSeq version 2). The mean patient age was 37 years with a female predilection (10:2). Preoperative fine needle aspiration was performed on 6 patients of which 4 were classified as "malignant," whereas 2 were classified as "follicular lesion of undetermined significance...

BACKGROUND: To determine if a group social skills intervention program improves social competence and quality of life (QOL) in pediatric brain tumor survivors (PBTS). METHODS: We conducted a randomized control trial in which PBTS (8-16 years old, off therapy for over 3 months) were allocated to receive social skills training (eg, cooperation, assertion, using social cognitive problem solving strategies, role playing, games, and arts and crafts) in 8 weekly 2-hour sessions, or an attention placebo control (games and arts and crafts only)...

INTRODUCTION: Diffuse intrinsic pontine gliomas (DIPG) constitute 10-15% of all brain tumors in the pediatric population; currently prognosis remains poor, with an overall survival of 7-14 months. Recently the indication of DIPG biopsy has been enlarged due to the development of molecular biology and various ongoing clinical and therapeutic trials. Classically a biopsy is performed using a stereotactic frame assisted procedure but the workflow may sometimes be heavy and more complex especially in children...

High-grade glioma (HGG) is a group of primary malignant brain tumors with dismal prognosis. Whereas adult HGG has been studied extensively, childhood HGG, a relatively rare disease, is less well-characterized. Here, we present two novel platelet-derived growth factor (PDGF)-driven mouse models of pediatric supratentorial HGG. Tumors developed from two different cells of origin reminiscent of neural stem cells (NSC) or oligodendrocyte precursor cells (OPC). Cross-species transcriptomics showed that both models are closely related to human pediatric HGG as compared with adult HGG...
