Abstract
Pediatric optic pathway/hypothalamic gliomas (OPHG) pose challenges in treatment due to their location and proximity to vital structures. Surgical resection plays a key role in the management of OPHG especially when the tumor exhibits mass effect and causes symptoms. However, data regarding outcomes and complications of surgical resection for OPHG remains heterogenous. The authors performed a systematic review on pediatric OPHG in four databases: PubMed, EMBASE, Cochrane Library, and Google Scholar. We included studies that reported on the visual outcomes and complications of OPHG resection. A meta-analysis was performed and reported per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. A total of 26 retrospective studies were included. Seven hundred ninety-seven pediatric patients with OPHG undergoing surgical resection were examined. A diagnosis of NF1 was confirmed in 9.7%. Gross total resection was achieved in 36.7%. Intraorbital optic pathway gliomas showed a significantly higher gross total resection rate compared to those located in the chiasmatic/hypothalamic region (75.8% vs. 9.6%). Postoperatively, visual acuity improved in 24.6%, remained unchanged in 68.2%, and worsened in 18.2%. Complications included hydrocephalus (35.4%), anterior pituitary dysfunction (19.6%), and transient diabetes insipidus (29%). Tumor progression post-resection occurred in 12.8%, through a mean follow-up of 53.5 months. Surgical resection remains an essential strategy for treating symptomatic and large pediatric OPHG and can result in favorable vision outcomes in most patients. Careful patient selection is critical. Patients should be monitored for hydrocephalus development postoperatively and followed up to assess for tumor progression and adjuvant treatment necessity.

Abstract
Pediatric optic pathway gliomas (OPG) are low-grade brain tumors characterized by slow progression and invalidating visual loss. Common therapeutic strategies include surgery, radiotherapy, chemotherapy, and combinations of these modalities, but despite the different treatment strategies, no actual treatment exists to prevent or revert visual impairment. Nowadays, several reports of the literature show promising results regarding NGF eye drop instillation and improvement of visual outcome. Such results seem to be related with the NGF-linked prevention in caspase activation, which reduces retinal ganglion cell loss.Reducing retinal ganglion cell loss results clinically in visual field improvement as well as visual electric potential and optical coherence tomography gain. Nonetheless, visual acuity fails to show significant changes.Visual impairment represents nowadays one of the major issues in dealing with OPGs. Secondary to the interesting results offered by NGF eye drop administration, further studies are warranted to better comprehend potential treatment strategies.

Abstract
BACKGROUND Optic pathway and hypothalamic gliomas (OPHGs) are challenging to surgically remove owing to their anatomical relationship. We previously reported on surgical treatment outcomes over a 10-year time frame. The purpose of this study was to update the OPHG clinical outcomes for cases in which chemotherapy has become the primary treatment option. The role of surgery was also revisited. METHODS Patients with a diagnosis of OPHG who underwent treatment at Seoul National University Children's Hospital from February 1999 to July 2019 were included. A multidisciplinary approach was used to determine the patients' treatment plans. Chemotherapy was the first-line treatment for all patients. When symptoms of hydrocephalus existed, debulking surgery was performed to reopen the flow of cerebrospinal fluid. RESULTS The study included 47 patients with OPHGs. The mean age was 6.9 years. Neurofibromatosis 1 was diagnosed in 3 patients. The extent of removal was none or biopsy in 13 (28%) cases, partial resection in 23 (49%) cases, and subtotal to gross total resection in 11 (23%) cases. In 32 (68%) patients, chemotherapy was first-line treatment. Ascites after ventriculoperitoneal shunt occurred in 3 cases, and 2 cases were successfully managed with debulking surgery. Treatment outcomes showed a 5-year overall survival rate of 97.7% and a 5-year progression-free survival rate of 47.7%. CONCLUSIONS OPHG management using less invasive operations and chemotherapy as first-line treatment is feasible. Debulking surgery in patients with OPHGs may be considered in cases with cerebrospinal fluid pathway obstruction, progression despite chemotherapy or radiation, and refractory shunt-related ascites.

Abstract
Background: OPG accounts for 3−5% of childhood central nervous system (CNS) tumors and about 2% of pediatric glial lesions. Methods: Article selection was performed by searching PubMed, Web of Science, and Cochrane databases. Results: The pooled mortality rate was 0.12 (95%CI 0.09−0.14). Due to the unrepresentative data, improved and not changed outcomes were classified as favorable outcomes and worsened as unfavorable. Meta-analyses were performed to determine the rate of clinical and radiological favorable outcomes. In terms of visual assessment, the pooled rate of a favorable outcome in chemotherapy, radiotherapy, and surgery was 0.74, 0.81, and 0.65, respectively, and the overall pooled rate of the favorable outcome was 0.75 (95%CI 0.70−0.80). In terms of radiological assessment, the rate of a favorable outcome following chemotherapy, radiotherapy, and surgery was 0.71, 0.74, and 0.67, respectively, and the overall pooled rate of the favorable outcome is 0.71 (95%CI 0.65−0.77). The subgroup analysis revealed no significant difference in the rate of clinical and radiological favorable outcomes between the different treatment modalities (p > 0.05). Conclusion: Our analyses showed that each therapeutic modality represents viable treatment options to achieve remission for these patients.

Abstract
Introduction Neurofibromatosis type 1 (NF1) has an incidence of 1 in 2,000 to 3,000 individuals and in 15% is associated with optic pathway glioma (OPG). Given the variability in clinical presentation and related morbidity, a multidisciplinary approach for diagnosis and management of children with NF1 and OPG is required, but often lacks coordination and regular information exchange. Herein we summarize our experience and describe the care pathways/network provided by a multidisciplinary team. The role of the distinct team members is elucidated as well as the care amendments made over time. Methods We performed a retrospective single-center observational study, including children treated at our institution between 1990 and 2021. Inclusion criteria were clinical diagnosis of NF1, radiographic and/or histopathological diagnosis of OPG and age below 18 years. Patients being treated elsewhere were excluded from the study. Data was abstracted from each child’s health record using a standardized data collection form. Characteristics of children with NF1 and OPG were described using means (SD) and percentages. Outcomes were determined using Kaplan-Meier estimates. Results From 1990 to 2021, 1,337 children were followed in our institution. Of those, 195 were diagnosed with OPG (14.6%), including 94 (48.21%) females and 101 (51.79%) males. Comprehensive data were available in 150 patients. The mean (SD) age at diagnosis was 5.31(4.08) years (range: 0.8–17.04 years). Sixty-two (41.3%) patients remained stable and did not undergo treatment, whereas 88 (58.7%) patients required at least one treatment. The mean (SD) duration of follow up was 8.14 (5.46) years (range: 0.1–25.9 years; median 6.8 years). Overall survival was of 23.6 years (±1.08), comprising 5 deaths. A dedicated NF clinic, including pediatricians and a nurse, provides regular follow up and plays a central role in the management of children with NF1, identifying those at risk of OPG, coordinating referrals to Neuroradiology and other specialists as indicated. All children are assessed annually by Ophthalmology. Comprehensive care was provided by a multidisciplinary team consisting of Dermatology, Genetics, Neuro-oncology, Neuroradiology, Neurosurgery, Ophthalmology and Pediatrics. Conclusions The care of children with NF1 and OPG is optimized with a multidisciplinary team approach, coordinated by a central specialty clinic.

The role of imaging features and resection status in the survival outcome of sporadic optic pathway glioma children receiving different adjuvant treatments. Neurosurg Rev 2022; 45:2277-2287.

Abstract
Optic pathway glioma (OPG) is a rare brain tumor affecting children, with no standard treatment strategy. This study described the sporadic OPG survival outcomes after surgical treatment and analyzed the role of imaging features and resection status in children receiving different adjuvant treatments. This retrospective study included 165 OPG patients whose clinical information were obtained from the hospital record system. Tumor volume and residual tumor volume were calculated by delineating the lesion area. Kaplan-Meier method and Cox proportional hazards model were conducted to analyze the independent prognosis factor. A total of 165 patients were included in this study. Respectively, the 5-year overall survival (OS) and progression-free survival (PFS) were 87.58% and 77.87%. Residual tumor size and first adjuvant treatment (AT) after surgery were both associated with PFS. In patients with small-size residual tumors, there was no significant difference in PFS between the AT treatment groups. Moreover, age, exophytic cystic components, leptomeningeal metastases, and AT were associated with OS. In patients with exophytic cystic components and those with leptomeningeal metastases, there was no significant difference in OS. Our results revealed that OPG patients could avoid or defer AT by maximized resection. Age ≤ 2 years was a disadvantageous factor for OS. Patients with exophytic cystic components were more likely to benefit from primary surgery, and CT or RT was not beneficial for these patients. Patients with leptomeningeal metastases had a poor prognosis regardless of the treatment they received. Future prospective clinical studies are needed to develop more effective treatment regimens.

Abstract
OBJECT Optic pathway tumors (OPT) represent a challenge for pediatric neurosurgeons. Role of surgery is debated due to the high risk of iatrogenic damage, and in lasts decades it lost its importance in favor of chemotherapy. However, in some cases surgery is necessary to make biomolecular and histological diagnosis, to manage intracranial hypertension (IH) and to cooperate with medical therapies in controlling tumor relapse. With the aim to standardize selection of surgical OPT cases, we propose a simple, practical and reproducible classification. METHODS We retrospectively analyzed data of 38 patients with OPT treated at our institution (1990-2018). After careful analysis of MRI images, we describe a new classification system. Group 1: lesion limited to one or both optic nerve(s). Group 2: chiasmatic lesions extending minimally to hypothalamus. Group 3: hypothalamo-chiasmatic exophitic lesions invading the third ventricle; they can be further divided on the base of concomitant hydrocephalus. Group 4: hypothalamo-chiasmatic lesions extending widely in lateral direction, toward the temporal or the frontal lobes. Patients' data and adopted treatment are reported and analyzed, also depending on this classification. RESULTS Twenty children were operated on for treatment of OPT during the study period. Permanent clinical impairment was noted in 5 (25%) of operated patients, while visual improvement was noted in 1 patient. OS rate was 100% at 5 years, with a median follow up of 9 years (ranging from 2 to 23). Prevalence of intracranial hypertension and proportion of first-line surgical treatment decision were significantly higher in groups 3-4 compared to groups 1-2 (P<0.001 for both tests). CONCLUSION Surgery can offer a valuable therapeutic complement for OPT without major risk of iatrogenic damage. Surgery is indispensable in cases presenting with IH, as in groups 3 and 4 lesions. Eligibility of patients to surgery can be based on this new classification system.

Abstract
BACKGROUND Optic Pathway Gliomas (OPG) are the most common brain tumor in Neurofibromatosis 1 patients (NF1). They are found along the optic pathway and may involve the optic nerves, chiasm, retro-chiasmatic structures, and the optic radiations. NF1 associate OPG (NF1-OPG) have variable presentation, disease course and response to treatment. The optimal management is patient-specific and should be tailored by a multidisciplinary team. Age, sex, histology, and molecular markers may be important factors in the individualized decision-making process. Chemotherapy is the first-line treatment in cases of progressive tumors, and visual preservation is the main goal of treatment. PURPOSE In this paper we will review the disease, practical management, and recent advances of NF1-OPG.

Abstract
Reproductive health is a common concern and often a source of distress for male childhood, adolescent, and young adult cancer survivors. Clinical and epidemiologic research in survivor populations has identified alkylating agent chemotherapy, testicular radiation, and surgery or radiation to the genitourinary organs, lower spine, or the hypothalamic-pituitary region as risk factors for adverse reproductive outcomes, including impaired spermatogenesis, testosterone insufficiency, and sexual dysfunction. Much of the research on male survivors has focused on the outcome of fertility, using spermatogenesis, serum gonadotropins, and paternity as the measures. However, these studies often fail to account for the clinically relevant but difficult-to-quantify aspects of fertility such as sexual function, cancer-related delayed psychosocial development, medical comorbidities, and socioeconomic concerns. Clinical and basic science research has made significant contributions to improving reproductive outcomes for survivors, with recent advancements in the areas of fertility preservation, clinical assessment of reproductive function, and treatment of adverse reproductive outcomes. Furthermore, there is an emerging qualitative literature addressing the psychosexual aspects of male reproductive health, the clinical application of which will improve quality of life for survivors. This review summarizes the current survivorship literature on reproductive health outcomes for male survivors, including the epidemiology of impaired spermatogenesis, testosterone insufficiency, and sexual dysfunction; clinical and laboratory assessment of reproductive function; and established and investigational interventions to preserve reproductive function for patients newly diagnosed and survivors. Although survivorship research has made significant contributions to improving reproductive outcomes, additional scientific progress is needed in the areas of fertility preservation, risk assessment, and psychosexual support with the aim of optimizing reproductive health for current and future survivors.

Liu Y, Hao X, Liu W, Li C, Gong J, Ma Z, Tian Y. Analysis of Survival Prognosis for Children with Symptomatic Optic Pathway Gliomas Who Received Surgery. World Neurosurg 2017; 109:e1-e15. [PMID: 28986229 DOI: 10.1016/j.wneu.2017.09.144] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2017] [Revised: 08/30/2017] [Accepted: 09/01/2017] [Indexed: 01/31/2023]
Abstract
OBJECTIVE The feasibility and prognosis of surgical treatment for children with optic pathway gliomas (OPGs) is controversial. Therefore this study attempted to evaluate the effects of surgery and discuss prognostic factors related to the survival of children with symptomatic OPGs. MATERIALS AND METHODS One-hundred twenty-five children diagnosed with OPGs underwent surgery in the Department of Neurosurgery, Beijing Tiantan Hospital from 2003-2016. In this retrospective study, their demographics, clinical characteristics, treatments, and survival outcomes were investigated and summarized. RESULTS Among the 125 patients, the 5-year overall survival (OS) rate and progression-free survival (PFS) rate were 84.1% and 70.6%, respectively. In the univariate analysis, patients who received postoperative radiotherapy (RT) after surgery had significantly better 5-year OS and PFS rates than patients who did not receive RT (P < 0.001 for both comparisons), patients who were 3 years old had better PFS rates than younger patients (P < 0.001), and patients with endocrinology symptoms had significantly worse PFS rates than patients with other symptoms (P = 0.049). In the multiple regression analysis, postoperative treatment with RT and tumors with a lower pathologic grade were better predictors of OS. An age older than 3 years and postoperative treatment with RT were better predictors of PFS. CONCLUSIONS Surgery is safe and feasible for children with large volumes of OPGs and symptoms of functional impairment and obstructive hydrocephalus. Furthermore, adjuvant RT after surgery may significantly improve OS and PFS. The pathologic grade is an independent prognostic factor for OS, and the age at diagnosis is an independent prognostic factor for PFS.

Abstract
PURPOSE Trends in pre- and postoperative fluid, electrolyte and osmolarity changes, and incidence of diabetes insipidus (DI) were assessed in pediatric patients with anterior visual pathway gliomas (AVPGs). METHODS Thirty-three patients with AVPGs (age < 16 years) were divided into two groups: (1) no hypothalamic involvement [NHI; n = 17 (51.5 %) including optic (5, 15.2 %); chiasmal (5, 15.2 %); and optico-chiasmal (7, 21.2 %)] and (2) hypothalamic involvement [HI; n = 16 (48.5 %) including chiasmal-hypothalamic (12, 36.4 %) and optico-chiasmal-hypothalamic (4, 12.1 %)]. Frontotemporal transylvian decompression/biopsy was undertaken in 32 patients, while one patient (with severe diencephalic syndrome) was treated conservatively. Their endocrinal and fluid/electrolyte balance, serum osmolarity, and DI status were noted. Chi-square test compared clinical/endocrinological parameters, and unpaired T test evaluated mean daily water/electrolyte changes (p value < 0.05: significant). RESULTS Significant visual deterioration (perception of light (PL) positive (left: n = 4; right: n = 4) and PL negative (left: n = 5; right: n = 5) was encountered due to optic atrophy. Larger lesions (>3 cm), hydrocephalus [(NHI: n = 7, 41.18 %; HI: n = 12, 75 %), endocrinopathies (p = 0.047), Na(+)/K(+) derangements, and preoperative DI (n = 8, p = 0.004)] were present in the group HI. Increased postoperative urine output (almost double in those with hypothalamic involvement) and hypernatremia/hyperkalemia were seen in group HI until the sixth postoperative day (p < 0.05). Two patients with progressive hypernatremia without increased urine output showed dehydration on central venous pressure monitoring and improved with vasopressin administration. Five patients [NHI: n = 4 (23.5 %); HI: n = 1 (6.3 %)] had neurofibromatosis types I and 3 (NHI: n = 1, 5.9 %; HI: n = 2, 12.5 %) had a diencephalic syndrome. CONCLUSIONS Hypothalamic infiltration significantly increases the incidence of DI and fluid and electrolyte disturbances. Strict vigilance over postoperative fluid balance is mandatory during the first postoperative week. Rapidly rising serial serum sodium values without increased urine output mandates immediate central venous pressure measurement to detect DI associated with dehydration.

Abstract
OBJECT Optic pathway/hypothalamic gliomas (OPHGs) are generally benign tumors situated in an exquisitely sensitive brain region. The location and natural history of OPHGs has led to much debate about optimal treatment. This paper revisits the role of and optimal timing of debulking surgery in OPHG. METHODS This paper presents a series of cases managed by the neuro-oncology team at Alder Hey Children's Hospital and a single surgeon. Data were collected retrospectively for periods prior to 2009 and prospectively thereafter. Tailored treatment strategies were used, including observation and combinations of surgery, chemotherapy, and radiotherapy. Tumor control rates and outcomes are reviewed. RESULTS Forty-two patients were treated between 1998 and 2011. Their median age at diagnosis was 5 years 7 months. Nineteen patients were positive for neurofibromatosis Type 1 (NF1) and 23 patients were negative for NF1. The median duration of follow-up was 77 months (range 21.8-142.3 months). Presenting symptoms included visual impairment (in 50% of cases), headache (in 24%), and hypothalamic/pituitary dysfunction (in 29%). Twenty-two debulking procedures were performed in 21 patients. Four biopsies (3 open, 1 endoscopic) were also performed. The histological diagnosis was pilocytic astrocytoma in 21 patients and pilomyxoid astrocytoma in 2 patients. Ten patients (Group 1) had primary surgical debulking alone and were then observed. Four patients (Group 2) had surgical debulking, plus planned chemotherapy within 3 months. Seven patients (Group 3) required surgical debulking for progressive disease following a variety of treatments. Patient age had the greatest impact on subsequent tumor progression. In total, 13 patients received chemotherapy, 4 on initial presentation, 4 in combination with surgery, and 5 for further tumor progression. Five patients were treated with radiotherapy, 3 prior to referral to Alder Hey. Eleven patients required shunt insertion for hydrocephalus. Vision was stabilized for 74% of patients. The number of patients with hypothalamic/pituitary dysfunction increased from 12 at presentation to 16 by the end of treatment. The overall survival rate was 93%. Three patients died-1 from tumor progression, 1 from infective complications from tumor biopsy, and 1 from a spontaneous posterior fossa hemorrhage. NF1 was associated with improved outcome-fewer patients required active intervention and rates of visual impairment and/or or hypothalamic/pituitary dysfunction were lower. CONCLUSIONS Good long-term survival and functional outcomes can be achieved in children with OPHG. Tumor control was achieved through an individualized approach using surgery, chemotherapy, or radiotherapy in varied combinations. The authors aim to limit radiotherapy to cases involving older children in whom other therapies have failed, due to the well-described and often devastating late effects associated with midline cranial irradiation. Surgery has a clear role for diagnosis, tumor control, and relief of mass effect. In particular, primary surgical debulking of tumor (without adjuvant therapy) is safe and effective. Recent advances in intraoperative MRI may add value and need further assessment.

Abstract
Optic pathway gliomas account for 3-5% of all pediatric CNS tumors and represent the most common intrinsic optic nerve tumors. These tumors occur preferentially during the first decade of life and are particularly frequent in children with neurofibromatosis type 1. Although optic pathway gliomas are low-grade tumors, their behavior can be aggressive, and their management is often challenging. Their management includes observation, surgery, chemotherapy and radiation. The role of each modality is discussed as well as current and future developments in treatment, in particular targeted therapies that are currently being investigated.

Hypothalamic-pituitary lesions in pediatric patients: endocrine symptoms often precede neuro-ophthalmic presenting symptoms. J Pediatr 2012; 161:855-63. [PMID: 22727865 DOI: 10.1016/j.jpeds.2012.05.014] [Citation(s) in RCA: 69] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2011] [Revised: 04/10/2012] [Accepted: 05/02/2012] [Indexed: 01/24/2023]
Abstract
OBJECTIVE To evaluate whether analyses of clinical and endocrine presenting symptoms could help to shorten the time to diagnosis of hypothalamic-pituitary lesions in children. STUDY DESIGN A retrospective, single-center, cohort study of 176 patients (93 boys), aged 6 years (range, 0.2-18 years), with hypothalamic-pituitary lesions was performed. RESULTS The lesions were craniopharyngioma (n = 56), optic pathway glioma (n = 54), suprasellar arachnoid cyst (n = 25), hamartoma (n = 22), germ cell tumor (n = 12), and hypothalamic-pituitary astrocytoma (n = 7). The most common presenting symptoms were neurologic (50%) and/or visual complaints (38%), followed by solitary endocrine symptoms (28%). Precocious puberty led to diagnosis in 19% of prepubertal patients (n = 131), occurring earlier in patients with hamartoma than in patients with optic-pathway glioma (P < .02). Isolated diabetes insipidus led to diagnosis for all germ-cell tumors. For 122 patients with neuro-ophthalmic presenting symptoms, the mean symptom interval was 0.5 year (95% CI, 0.4-0.6 year), although 66% of patients had abnormal body mass index or growth velocity, which preceded the presenting symptom interval onset by 1.9 years (95% CI, 1.5-2.4 years) (P < .0001) and 1.4 years (95% CI, 1-1.8 years) (P < .0001), respectively. Among them, 41 patients were obese before diagnosis (median 2.2 years [IQR, 1-3 years] prior to diagnosis) and 35 of them had normal growth velocity at the onset of obesity. The sensitivity of current guidelines for management of childhood obesity failed to identify 61%-85% of obese children with an underlying hypothalamic-pituitary lesion in our series. CONCLUSIONS Endocrine disorders occurred in two-thirds of patients prior to the onset of the neuro-ophthalmic presenting symptom but were missed. Identifying them may help to diagnose hypothalamic-pituitary lesions earlier.

Abstract
INTRODUCTION The current SIOP (International Society for Paediatric Oncology)-LGG (low grade glioma) study protocol allows chiasmatic tumours identified as LGG on the basis of neuroradiological characteristics to be treated without histological verification. As some tumours do not respond well to treatment, the search for molecular tissue markers will gain importance for future studies. Anecdotal observations of infarctions after surgery for chiasmatic tumours during central reviewing initiated this study. MATERIALS AND METHODS In 84 patients, histology was obtained during 102 interventions in the years 1992-2009 by 33 biopsies, 67 partial/subtotal and 2 total resections. Median age at the time of operation was 5 years (mean 5 years 11 months). We could identify 17 infarctions following partial resection of chiasmatic LGG. Biopsies were not complicated by infarction. Children developing infarction were considerably younger (median 3 years; mean 4 years 5 months) than the patients without infarction (median 5 years 4 months; mean 6 years 2 months). A total of 51 patients with cerebellar LGG (median 7 years; mean 7 years 4 months) served as a control group, with 65 surgical procedures (2 biopsies, 22 partial/subtotal resections and 41 total resections) performed in the years 2004-2009. Only one total resection (1.5%) in this group was followed by infarction. CONCLUSION Partial/subtotal resections of chiasmatic LGG in our study population bear a considerable risk for infarction especially in young children. As there is currently no evidence for a better outcome after tumour resection, we suggest that the sampling of tumour tissue should be performed via biopsies whenever possible.

Abstract
A 10-month-old male presented with sudden growth failure and cachexia. MRI showed a chiasma of the hypothalamic mass. Biopsy was avoided due to operative risks. Three cycles of chemotherapy were given, resulting in stable disease on MRI, but growth failure despite attempts at enteral feeding. Surgical biopsy was then performed. A 30% tumor reduction was observed on post-operative imaging. Pathological examination revealed a pilocytic astrocytoma. After surgery, the child gained weight and his growth curve returned to normal. Enteral feeding was discontinued. After 4-year of follow-up, neurological development remains normal, with no residual or endocrine abnormalities.

Abstract
Optic pathway/hypothalamic pilocytic astrocytomas in children are usually treated with chemotherapy following a surgical biopsy. In this report, we retrospectively considered the role of surgical intervention. In a series of 25 patients without neurofibromatosis type 1, the median age at initial treatment was 3.1 years (range, 0-15 years). Twenty cases were verified by histology, and five cases were diagnosed by MRI findings. Twenty-three patients received chemotherapy. All patients were alive at median follow-up of 66 months. Aims of surgery at the initiation of treatment were biopsy in 12 cases (1 stereotactic and 11 craniotomies) and debulking in 7 cases. The 11 open biopsies revealed pilocytic astrocytoma; however, noticeable complications occurred in five children after the biopsies. Review of preoperative MRIs showed that all had typical findings indicating pilocytic astrocytoma. The open biopsy offered no noteworthy benefit for the patients despite surgical risk and delay of chemotherapy. The extent of the seven resection surgeries was 70% or less removal, and postoperative adjuvant therapy was needed for six of the seven patients. The remaining six children who did not undergo surgery obtained remission with chemotherapy alone. After relapse in nine patients, 15 bulk-reduction surgeries were performed. Surgical resection was not curative in any patient. In five patients, mostly older children, cystic expansion of tumor was partially resected, resulting in additional remission. In conclusion, considering the risk of open surgery and the effectiveness of chemotherapy, the role of surgical intervention is restricted to bulk-reduction surgery only when it is inevitable, especially at relapse after chemotherapy.

Abstract
Optic pathway-hypothalamic gliomas (OPHGs) are rare, often unresectable tumors that mostly occur in childhood. Their biological behavior is unpredictable, although they tend to follow an aggressive clinical course in infants and a benign course in children with neurofibromatosis type 1. Optimal management is still controversial. Nonprogressing OPHGs are usually followed by surveillance alone. Surgery is advocated for progressing tumors to decompress the optic pathways, obtain a quick relief from intracranial hypertension and allow histologic examination (when needed). The current trend is in favor of conservative surgical behavior, except for resectable tumors. Chemotherapy is increasingly used in the management of OPHGs, especially in infants, to delay radiotherapy. Carboplatin and vincristine are the most frequently used drugs, although several chemotherapeutic agents in different combinations are currently employed with good results. Radiotherapy is utilized in children over 5 years of age as an adjuvant or as an alternative to surgery. The prognosis of OPHGs is quite good, with regard to the overall survival rate (70-100% at 5 years), but less favorable in terms of late morbidity.

Abstract
OBJECTIVE To present our experience in the treatment of child optic pathway gliomas in the last 25 years. MATERIAL AND METHODS Seventeen children under 10 years of age have been analyzed and assessed from clinic, ophthalmologic, endocrinologic, neurological, neuropathologic, and imaginologic points of view. RESULTS Predominance of female patients, 10 girls and 7 boys between 6 and 122 months old; mean age was 3 years and 8 months. The most frequent symptoms have been ophthalmologic and visual alterations in all 17 patients, endocrine alterations in 10, and neurological signs in 6. One of the patients presented neurofibromatosis type 1 (NF1), another patient had Down syndrome. Diagnosed using computed tomography or/and magnetic resonance imaging, histological studies showed pilocytic astrocytomas in 13 cases and a fibrillary astrocytoma grade II in 1 case. There were three patients without histological diagnosis; one of them had NF1. The treatment consisted of surgery, external beam radiotherapy, chemotherapy, and brachytherapy with iodine 125, separately or combined. Five patients died; the causes were secondary tumors in two children, tumor recurrence in one, sepsis secondary to respiratory and urinary tract infections in the child with Down syndrome, and finally, hydrocephaly due to hyperproteinorachia of tumor origin in one. Average survival was 89 months. CONCLUSION Chemotherapy and brachytherapy are therapeutic methods to be considered, especially in children under 5. Marsupialization of the residual cyst into the ventricular system postradio or oncolytic treatment through endoscopic or stereotactic techniques is useful in the treatment of endocranial hypertension and/or hypothalamic compression in these patients.

Abstract
Neurofibromatosis Type 1 (NF1) is one of the most common inherited diseases in humans. It is caused by a mutation in the NF1 gene on chromosome 17, and is associated with numerous central and peripheral nervous system manifestations. Children with NF1 are at high risk of harboring numerous lesions that may require the attention of a neurosurgeon. Some of these include optic nerve gliomas, hydrocephalus, intraspinal tumors, and peripheral nerve tumors. Although most of the neoplasms that affect the brain, spine, and peripheral nerves of children are low-grade lesions, there is a small but real risk that some of these lesions may become high grade over time, requiring other forms of therapy than surgery alone. Other associated disorders that may result from NF1 in childhood include Chiari malformation Type I, scoliosis, and pulsating exophthalmos from the absence of the sphenoid wing. In this review, the major lesions that are found in children with NF1 are reviewed as well as the types of treatment that are offered by neurosurgeons and other members of the treating team. Today, optimum care of the child with NF1 is provided by a multidisciplinary team comprising neurosurgeons, neurologists, ophthalmologists, radiologists, orthopedic surgeons, and plastic surgeons.

Abstract
Neurofibromatosis Type 1 (NF1) is one of the most common inherited diseases in humans. It is caused by a mutation in the NF1 gene on chromosome 17, and is associated with numerous central and peripheral nervous system manifestations. Children with NF1 are at high risk of harboring numerous lesions that may require the attention of a neurosurgeon. Some of these include optic nerve gliomas, hydrocephalus, intraspinal tumors, and peripheral nerve tumors. Although most of the neoplasms that affect the brain, spine, and peripheral nerves of children are low-grade lesions, there is a small but real risk that some of these lesions may become high grade over time, requiring other forms of therapy than surgery alone. Other associated disorders that may result from NF1 in childhood include Chiari malformation Type I, scoliosis, and pulsating exophthalmos from the absence of the sphenoid wing. In this review, the major lesions that are found in children with NF1 are reviewed as well as the types of treatment that are offered by neurosurgeons and other members of the treating team. Today, optimum care of the child with NF1 is provided by a multidisciplinary team comprising neurosurgeons, neurologists, ophthalmologists, radiologists, orthopedic surgeons, and plastic surgeons.

Abstract
Von Hippel-Lindau disease (VHL) and neurofibromatosis type 1 (NF 1) are hereditary multitumor syndromes that show associated ocular manifestations. Capillary retinal angioma, a benign vascular tumor, is the classical ocular lesion in VHL. It often appears as the first manifestation of the disease and may thus lead to the diagnosis of VHL. Since small angiomas can be treated easily by laser photocoagulation, a regular ocular screening of VHL patients is recommended. Ocular manifestations of NF 1 are more diverse as compared to VHL. Lisch nodules of the iris are an important diagnostic criteria of NF 1 since they can be found in almost every affected patient. Optic glioma can occur both intraorbitally and intracranially. The intraorbital form causes progressive protrusion of the globe and eventually blindness. Extension of the tumor beyond the chiasm worsens the prognosis quoad vitam. The hallmark of NF 1, namely cutaneous neurofibroma can cause visual impairment when affecting the skin of the eyelids. The rare intraorbital pexiform neurofibroma is associated with abnormal development of the orbital bones and infantile glaucoma. It may result in orbital mass effects and therefore may need surgical excision.

Abstract
Primary brain tumors are the most common solid neoplasms of childhood. The diagnosis of brain tumors in the general pediatric population remains challenging. Nevertheless, it is clear that refinements in imaging, surgical technique, and adjunctive therapies have led to longer survival and an improving quality of life in children with brain tumors.
