Treatment Outcome of Response-Based Radiation Therapy in Children and Adolescents With Central Nervous System Nongerminomatous Germ Cell Tumors: Results of a Prospective Study. Int J Radiat Oncol Biol Phys 2024; 119:858-868. [PMID: 38122991 DOI: 10.1016/j.ijrobp.2023.12.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Revised: 11/08/2023] [Accepted: 12/02/2023] [Indexed: 12/23/2023]
Abstract
PURPOSE The optimal dose and range of radiation therapy for central nervous system nongerminomatous germ cell tumors (NGGCTs) have not been uniformly established. Therefore, this study aimed to investigate the effect of individualized radiation therapy, based on the response to induction chemotherapy combined with surgery, on the prognosis of patients with NGGCTs. METHODS AND MATERIALS Based on the imaging examination and tumor markers after induction chemotherapy and pathologic results of second-look surgery, patients with NGGCT received different radiation therapy strategies, including 30.6 Gy whole ventricular irradiation + tumor-bed boost to 54 Gy, 30.6 Gy craniospinal irradiation + tumor-bed boost to 54 Gy, 36 Gy craniospinal irradiation + tumor-bed boost to 54 Gy, and 36 Gy craniospinal irradiation + 54 Gy tumor-bed boost with 45 Gy to metastatic spinal lesions. RESULTS A total of 51 patients were enrolled between January 2015 and March 2021, with a median age of 10.3 years. The 3-year event-free survival and overall survival (OS) of the entire cohort were 70.2% ± 6.9% and 77.5% ± 6.0%, respectively. The 3-year OS of patients achieving partial response after induction chemotherapy was higher than that of patients with stable disease (P = .03) or progressive disease (P = .002). The 3-year event-free survival and OS of the 18 patients receiving 30.6 Gy whole ventricular irradiation and 54 Gy tumor-bed boost were 88.9% ± 7.4% and 94.4% ± 5.4%, respectively. CONCLUSIONS The results suggest that an individualized radiation therapy strategy based on response to induction chemotherapy and surgery is a feasible and promising means of achieving reduction in dose and extent of radiation in patients while still providing good response.

[PMID: 38438767 DOI: 10.1007/s11060-024-04626-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Accepted: 02/28/2024] [Indexed: 03/06/2024]
Abstract
PURPOSE To investigate the clinical characteristics and predictive factors associated with delayed diagnosis in patients with sellar germ cell tumors (GCTs), aiming for early diagnosis. METHODS A total of 345 patients with sellar GCTs were retrospectively collected. Patients were classified into a delayed diagnosis group (> 6 months from onset to diagnosis) and a non-delayed diagnosis group (≤ 6 months). We compared general characteristics, clinical symptoms, diagnostic methods, treatment strategies, tumor prognosis, and pituitary function between the two groups. Predictive factors for delayed diagnosis were explored using multivariate logistic regression analysis. RESULTS 225 patients (65.2%) experienced delayed diagnosis. Although there was no association between delayed diagnosis and survival rates or tumor recurrence rates, the delayed diagnosis group had a higher incidence of central diabetes insipidus, central adrenal insufficiency, central hypothyroidism, central hypogonadism, and growth hormone deficiency. Moreover, polyuria/polydipsia (OR 5.46; 95% CI 2.33-12.81), slow growth (OR 5.86; 95% CI 2.61-13.14), amenorrhea (OR 6.82; 95% CI 2.68-17.37), and germinoma (OR 4.99; 95% CI 1.08-3.61) were associated with a higher risk of delayed diagnosis, while older age of onset (OR 0.88; 95% CI 0.84-0.94) and nausea/vomiting (OR 0.31; 95% CI 0.15-0.63) contributed to earlier diagnosis. CONCLUSION In patients with sellar GCTs, delayed diagnosis is common and linked to increased pituitary dysfunction. The initial symptoms of slow growth, polyuria/polydipsia, and amenorrhea, as well as germinoma with negative tumor markers, predict the possibility of a delayed diagnosis. Early diagnosis is crucial to minimize the impact of sellar GCTs on pituitary function.

Abstract
Basal ganglia germinomas (BGGs) are rare lesions. Because of the atypical features of early-stage clinical symptoms and imaging characteristics, BGGs are easily misdiagnosed with non-tumorous conditions. This article presented cases of 2 young male patients who came to the hospital due to right arm weakness. Brain Magnetic Resonance Imaging (MRI) images in the first case revealed a lobulated mixed component mass on the left basal ganglia. The solid part showed restricted diffusion on diffusion-weighted imaging, heterogeneous strong enhancement, and no signal of calcification or bleeding. The second case in the left putamen showed hypointensity on T2*, mild enhancement, and atrophy of the ipsilateral cerebral peduncle, increased choline, and decreased n-acetyl-aspartate (NAA) on spectroscopy. Follow-up MRI after 6 months showed a mass increase in size and hypointensity part on T2*. BGGs have been confirmed on biopsy in both cases. With isolated chemotherapy application, there is no sign of remission in the first patient. The second patient was treated with chemotherapy and radiotherapy, and MRI images after treatment showed a complete response.

Abstract
BACKGROUND A pineal region tumor is a rare intracranial tumor, and its specific location leads to its own characteristics. This study aimed to provide some insight for medical practice in the care of pineal region tumors. We investigated the key epidemiological characteristics and survival prognosis of pineal tumors based on the epidemiological data from the Surveillance, Epidemiology, and End Results database. METHODS Data of pineal region tumor patients from 1975 to 2019 were extracted from the Surveillance, Epidemiology, and End Results database. The data were divided into 3 pathologic groups: germ cell tumors, pineal parenchymal tumors, and other. The patients' overall survival (OS) was analyzed using the Kaplan-Meier method. The prognostic effects of the patient characteristics on OS were explored using the Cox proportional hazard model. The analysis results are presented as tabular data, Kaplan-Meier plots, forest plots, and nomograms. A calibration curve was used to verify the nomograms. All analyses were performed for all patients overall and stratified by pathological group using SPSS and R language. RESULTS Based on the predefined inclusion and exclusion criteria, 628 patients were included in this study, of whom 440 (70.1%) were male and 188 (29.9%) were female. Most patients were aged 0-19 years. The pathological type was germinoma for 225 patients (35.8%). Age, surgery, behavioral code, and pathology were significant factors for OS. A calibration curve was used to verify that the nomograms had a good prediction effect. CONCLUSIONS An intuitive nomogram was developed and verified and can predict the prognosis of patients with pineal tumors.

Abstract
INTRODUCTION Radiotherapy-induced glioblastomas (RIGB) are a well-known late and rare complication of brain irradiation. Yet the clinical, radiological and molecular characteristics of these tumors are not well characterized. METHODS This was a retrospective multicentre study that analysed adult patients with newly diagnosed glioblastoma over a 10-year period. Patients with RIGB were identified according to Cahan's criteria for radiation-induced tumors. A case-control analysis was performed to compare known prognostic factors for overall survival (OS) with an independent cohort of IDH-1 wildtype de novo glioblastomas treated with standard temozolomide chemoradiotherapy. Survival analysis was performed by Cox proportional hazards regression. RESULTS A total of 590 adult patients were diagnosed with glioblastoma. 19 patients (3%) had RIGB. The mean age of patients upon diagnosis was 48 years ± 15. The mean latency duration from radiotherapy to RIGB was 14 years ± 8. The mean total dose was 58Gy ± 10. One-third of patients (37%, 7/19) had nasopharyngeal cancer and a fifth (21%, 4/19) had primary intracranial germinoma. Compared to a cohort of 146 de novo glioblastoma patients, RIGB patients had a shorter median OS of 4.8 months versus 19.2 months (p-value: <.001). Over a third of RIGBs involved the cerebellum (37%, 7/19) and was higher than the control group (4%, 6/146; p-value: <.001). A fifth of RIGBs (21%, 3/19) were pMGMT methylated which was significantly fewer than the control group (49%, 71/146; p-value: .01). For RIGB patients (32%, 6/19) treated with re-irradiation, the one-year survival rate was 67% and only 8% for those without such treatment (p-value: .007). CONCLUSION The propensity for RIGBs to develop in the cerebellum and to be pMGMT unmethylated may contribute to their poorer prognosis. When possible re-irradiation may offer a survival benefit. Nasopharyngeal cancer and germinomas accounted for the majority of original malignancies reflecting their prevalence among Southern Chinese.

Abstract
Pediatric brain tumors are different to those found in adults in pathological type, anatomical site, molecular signature, and probable tumor drivers. Although these tumors usually occur in childhood, they also rarely present in adult patients, either as a de novo diagnosis or as a delayed recurrence of a pediatric tumor in the setting of a patient that has transitioned into adult services.Due to the rarity of pediatric-like tumors in adults, the literature on these tumor types in adults is often limited to small case series, and treatment decisions are often based on the management plans taken from pediatric studies. However, the biology of these tumors is often different from the same tumors found in children. Likewise, adult patients are often unable to tolerate the side effects of the aggressive treatments used in children-for which there is little or no evidence of efficacy in adults. In this chapter, we review the literature and summarize the clinical, pathological, molecular profile, and response to treatment for the following pediatric tumor types-medulloblastoma, ependymoma, craniopharyngioma, pilocytic astrocytoma, subependymal giant cell astrocytoma, germ cell tumors, choroid plexus tumors, midline glioma, and pleomorphic xanthoastrocytoma-with emphasis on the differences to the adult population.

Abstract
Cases of young patients combined with intracranial germinoma and parathyroid adenoma are extremely rare. A 6.25-year-old boy was diagnosed with growth hormone deficiency at his first visit and was then treated with growth hormone substitution. Later, he was clinically diagnosed with central diabetes insipidus (CDI) and primary hyperparathyroidism, whereas no abnormal imaging evidence was identified, except for a thickened pituitary stalk. Due to persistent follow-up, parathyroid adenoma and intracranial germinoma were verified in succession. The patient had derived benefits from parathyroidectomy and chemotherapy plus radiotherapy. We concluded that children and adolescents who present with CDI and pituitary stalk thickening should undergo repeated screenings for underlying intracranial germinoma. Multiple lesions involving the parathyroid gland and pituitary should alert physicians to the possibility of multiple endocrine neoplasia or other inherited diseases; therefore, genetic screening is recommended.

Abstract
PURPOSE OF REVIEW Intracranial germinomas constitute a rare brain tumor entity of unknown etiology, characterized by unique histopathology and molecular biology. In this manuscript, we review the literature focusing on the epidemiology, histopathology with molecular biology, clinical presentation with emphasis on tumor location, diagnostic workup, and current treatment strategies with related clinical outcomes of intracranial germinomas. RECENT FINDINGS Although the optimal treatment strategy remains a matter of debate, intracranial germinomas respond well to radiotherapy, chemotherapy, or a combination of both and are characterized by very high cure and survival rates. It is well-known that early discrimination of germinomas from other intracranial neoplasms facilitates the timely initiation of appropriate treatment, thereby contributing to the reduction of morbidity as well as mortality. Ongoing research will need to be directed towards discovering and refining reliable parameters for early diagnosis and evaluation of prognosis in patients with intracranial germinomas.

Abstract
Pineal apoplexy is a rare clinical condition. Its common symptoms include headaches, nausea, vomiting, ataxia, and gaze paralysis. These symptoms are mainly caused by obstructive hydrocephalus or direct compression of the cerebellum or midbrain. There have been no previous reports on the development of a recurrent pineal parenchymal tumor of intermediate differentiation (PPTID) with intratumoral hemorrhage. We report a case of PPTID with intratumoral hemorrhage. A 44-year-old woman developed recurrent PPTID following tumor removal and ventriculoperitoneal shunting in 2010. She visited the emergency department in April 2021 for sudden-onset dizziness and generalized weakness. Blurring of vision occurred and progressed over the previous month. Neurological examination revealed upward conjugate gaze paralysis. Brain computed tomography revealed a hyperdense lesion in the pineal region, and a recurrent tumor with hemorrhage was suspected. Magnetic resonance imaging of the brain confirmed a pineal tumor with intratumoral hemorrhage. The pineal tumor and hematoma were surgically removed via the suboccipital transtentorial approach. The patient was discharged from the hospital 2 weeks after the surgery. The pathological findings were consistent with the diagnosis of recurrent PPTID. PPTID is a rare tumor, accounting for less than 0.1% of primary central nervous system tumors. Pineal apoplexy is rare, and its incidence and clinical significance remain unclear. There have only been nine reported cases of pineal apoplexy, associated with pineal parenchymal tumors. The recurrence of PPTID with apoplectic hemorrhage after 10 years has not been reported. Despite its rarity, PPTID with apoplexy should be considered in patients with PPTID who develop sudden-onset neurological symptoms.

Abstract
Glioma is a major brain tumor, and the associated mortality rate is very high. Contemporary therapies provide a chance of survival for 9-12 months. Therefore, a novel approach is essential to improve the survival rate. Sonic hedgehog (Shh) cell signaling is critical for early development in various tumors. This investigation attempted to explore the potential interaction and regulation of Shh-Gli1 cell signaling in association with paired box 6 (Pax6) and isocitrate dehydrogenase 2 (IDH2). The expression pattern of Shh, Gli1, Pax6, and IDH2 was examined by transcriptome analysis, immunohistochemistry, and confocal images. The results suggest the interaction of Shh-Gli1 cell signaling pathway with Pax6 and IDH2 and potential regulation. Thereafter, we performed protein-protein docking and molecular dynamic simulations (MDS) of Gli1 with Pax6 and IDH2. The results suggest differential dynamic interactions of Gli1-IDH2 and Gli1-Pax6. Gli1 knockdown downregulated the expression of Pax6 and upregulated the expression of IDH2. Moreover, Gli1 knockdown decreased the expression of the drug resistance gene MRP1. The knockdown of Pax6 gene in glioma cells downregulated the expression of Gli1 and IDH2 and promoted cell proliferation. Moreover, the efficacy of the treatment of glioma cells with temozolomide (TMZ) and Gli1 inhibitor GANT61 was higher than that of TMZ alone. MDS results revealed that the interactions of Gli1 with IDH2 were stronger and more stable than those with Pax6. Intriguingly, inhibition of Pax6 promoted glioma growth even in the presence of TMZ. However, the tumor-suppressive nature of Pax6 was altered when Gli1 was inhibited by GANT61, and it showed potential oncogenic character, as observed in other cancers. Therefore, we conclude that Pax6 interacted with IDH2 and Gli1 in glioma. Moreover, the Shh-Gli1-IDH2/Pax6 cell signaling axis provides a new therapeutic approach for inhibiting the progression of the disease and mitigating drug resistance in glioma.

Burnham EL, Tomita T. Histogenesis of intracranial germ cell tumors: primordial germ cell vs. embryonic stem cell. Childs Nerv Syst 2023; 39:359-368.

Abstract
INTRODUCTION Intracranial germ cell tumor (iGCT) is a rare disorder and often occurs during childhood and adolescence. iGCTs are frequently localized in pineal region and hypothalamic-neurohypophyseal axis (HNA). In spite of well-established clinical and pathological entity, histogenesis of iGCTs remains unsettled. Current theories of histogenesis of iGCTs include germ cell theory (from primordial germ cells (PGCs) of aberrant migration) and stem cell theory (transformed embryonic stem (ES) cells). In order to comprehend the histogenesis, we revisit the origin, migration, and fate of the human PGCs, and their transformation processes to iGCT. DISCUSSION In "germ cell theory," transformation of ectopic PGCs to iGCT is complex and involves multiple transcription factors. Germinoma is derived from ectopic PGCs and is considered a prototype of all GCTs. Non-germinomatous germ cell tumors (NGGCTs) develop from more differentiated counterparts of embryonic and extra-embryonic tissues. However, there is a distinct genomic/epigenomic landscape between germinoma and NGGCT. ES cells transformed from ectopic PGCs through molecular dysregulation or de-differentiation may become the source of iGCT. "Stem cell theory" is transformation of endogenous ES cells or primitive neural stem cell to iGCTs. It supports histological diversity of NGGCTs because of ES cell's pluripotency. However, neural stem cells are abundantly present along the subependymal zone; therefore, it does not explain why iGCTs almost exclusively occur in pineal and HNA locations. Also, the vast difference of methylation status between germinoma and NGGCT makes it difficult to theorize all iGCTs derive from the common cellular linage. CONCLUSION Transformation of PGCs to ES cells is the most logical mechanism for histogenesis of iGCT. However, its detail remains an enigma and needs further investigations.

Abstract
Pediatric pineal region tumors consist of tumors of pineal gland origin and parapineal origin. The former are comprised of germ cell tumor (GCT) and pineal parenchymal tumor. The latter originate from the surrounding neural structures, such as the midbrain and thalamus; thus, they are often benign gliomas during childhood. Pineal region tumors often cause obstructive hydrocephalus, which is the main cause of presenting symptoms. Advanced imaging discloses precise location and extension of the tumor and associated anomalies such as hydrocephalous, dissemination, hemorrhage, etc. Hydrocephalus has been managed with CSF diversion, mostly using an endoscopic third ventriculostomy. Because of different treatment paradigms for each tumor type, histological confirmation is needed either through biopsy, tumor markers for GCTs, and/or surgical resection sampling. Radical resection of these tumors remains a challenge due to their deep-seated location and involvement of delicate neural and vascular structures. Comparison of common craniotomy approaches, occipital transtentorial (OT) and infratentorial supracerebellar (ITSC), is reviewed for their advantages and disadvantages. Surgical area exposure and blind spots are important factors for successful tumor removal. The surgical techniques and nuances that the author employs for tumor resection via a posterior interhemispheric transtentorial approach are presented.

Abstract
Primary germ cell tumors of the central nervous system (CNS) typically occur in the neurohypophysis, hypothalamus, or pineal gland and rarely in the spinal cord. We report a case of a spinal intramedullary tumor, which was first detected on magnetic resonance imaging (MRI) 41 months after the initial symptoms, with a verified pathological diagnosis of germinoma. The initial symptom was an abnormal sensation in the left plantar region that gradually worsened, resulting in severe sensory disturbance, difficulty in standing, and even bladder rectal disturbance. Repeated MRI after the onset failed to provide an imaging diagnosis. The MRI was performed 41 months after the onset and revealed a previously undiagnosed, contrast-enhancing spinal intramedullary neoplastic lesion at the Th11-12 level. Gross total resection of the tumor was successfully performed, and the pathology confirmed the diagnosis of pure germinoma. Postoperative chemotherapy, followed by local radiation, was successfully administered. Among primary germinomas of the CNS, occult germinoma that lacks imaging findings suggestive of tumors in the early stages of onset and becomes apparent over time is often reported as a primary neurohypophyseal germinoma, particularly in adolescents presenting with diabetes insipidus. In the present case, the lesion appeared to correspond to a primary occult germinoma of the intramedullary spinal cord.

Abstract
Primary central nervous system (CNS) germ cell tumors (GCT) are a rare heterogenous group of cancers, arising most commonly in the second decade of life. Through several clinical trials conducted around the world by various groups, the treatment approach for CNS GCT has advanced substantially with generally improved overall outcomes. In recent years, the goal of clinical trials has been focused on reduction of the radiotherapy burden and minimization of long-term toxicity. This review summarizes the current diagnostic and treatment regimens for CNS GCT, examines the controversies associated with these approaches, gaps in contemporary knowledge, and underscores the challenges we face. We also explore future directions in the management of CNS GCT with the ultimate overall aim of preserving curative outcomes, identifying novel biomarkers, and mitigating neurocognitive, endocrine, and psychological toxicity through prospective clinical studies.

Abstract
BACKGROUND AND AIMS Intracranial germ cell tumor (iGCT) survivors have multiple risk factors for growth hormone (GH) deficiency, a commonly reported late effect in childhood cancer survivors. The objective of this study is to examine the prevalence of GH deficiency among childhood iGCT survivors. METHODS Participants were previously enrolled in the Germ Cell Tumor Epidemiology Study (GaMETES), a case parent triad study conducted using the Children's Oncology Group registry protocols, including 216 cases with iGCTs. Data on late effects and outcomes are available for 129 iGCT cases who consented for a follow-up study including a self-administered questionnaire and medical record retrieval. GH deficiency was identified via self-report and validated through medical record review. Chi-squared and Fisher's exact tests were used to examine cases with GH deficiency predating iGCT detection. Logistic regression was used to identify predictors of GH deficiency as a late effect. RESULTS Of 129 iGCT cases who participated in the late effects study, 45% had GH deficiency; 18% had GH deficiency predating the iGCT and 27% developed GH deficiency within a median of 19 months after diagnosis. Younger age at diagnosis, suprasellar location, and higher radiation doses were associated with GH deficiency as a late effect. CONCLUSIONS GH deficiency is highly prevalent as an early clinical sign for iGCT and frequently arises as an early late effect after treatment. Additional investigation is needed to address earlier detection and treatment for this highly prevalent late effect in iGCT survivors.

Abstract
Background Ependymomas, pilocytic astrocytomas, medulloblastomas, and intracranial germ cell tumors occur relative frequently in children, but are rare central nervous system (CNS) tumors in adults. In this population-based survey, we established incidence, treatment, and survival patterns for these tumors diagnosed in adult patients (≥18 years) over a 30-year period (1989–2018). Methods Data on 1384 ependymomas, 454 pilocytic astrocytomas, 205 medulloblastomas, and 112 intracranial germ cell tumors were obtained from the Netherlands Cancer Registry (NCR) on the basis of a histopathological diagnosis. For each tumor type, age-standardized incidence rates and estimated annual percentage change were calculated. Trends in incidence and main treatment modalities were reported per 5-year periods. Overall survival was calculated using the Kaplan–Meier method, and relative survival rates were estimated using the Pohar-Perme estimator. Results Incidence and survival rates remained generally stable for pilocytic astrocytomas, medulloblastomas, and germ cell tumors. Increasing incidence was observed for spinal ependymomas, mostly for myxopapillary ependymomas, and survival improved over time for grade II ependymomas (P < .01). Treatment patterns varied over time with shifting roles for surgery in ependymomas and for chemotherapy and radiation in medulloblastomas and germinomas. Conclusions The study provides baseline information for highly needed national and international standard treatment protocols, and thus for further improving patient outcomes in these rare CNS tumors.

Abstract
The MDS Video Challenge continues to be the one of most widely attended sessions at the International Congress. Although the primary focus of this event is the presentation of complex and challenging cases through videos, a number of cases over the years have also presented an unusual or important neuroimaging finding related to the case. We reviewed the previous Video Challenge cases and present here a selection of those cases which incorporated such imaging findings. We have compiled these "imaging pearls" into two anthologies. The first focuses on pearls where the underlying diagnosis was a genetic condition. This second anthology focuses on imaging pearls in cases where the underlying condition was acquired. For each case we present brief clinical details along with neuroimaging findings, the characteristic imaging findings of that disorder and, finally, the differential diagnosis for the imaging findings seen.

Abstract
Bilateral optic neuropathy is uncommon in adults with a prevalence varying from 19% -50% of all optic neuropathies [1]. The most common etiology is Neuromyelitis Optica (NMO) or Devic’s disease. Other less frequent etiologies include myelin-oligodendrocyte-glycoprotein (MOG) antibody, syphilis, meningioma, post-vaccinal, post-infectious (chicken pox, human herpes virus 6), acute disseminated encephalomyelitis and idiopathic. Sequential optic neuropathy is seen in multiple sclerosis, but bilateral simultaneous optic neuropathy is rare [2]. When optic neuropathy involves posterior nerve segments, long segments and the optic chiasm, NMO should be suspected. If there is involvement of the hypothalamus, basal meninges, other cranial neuropathies, sarcoidosis must be considered [3]. Primary intracranial germinoma is a rare condition and should be included in the differential diagnosis, especially if there are atypical features and inadequate response to standard treatment [4].

Abstract
GnRH-independent precocious puberty (GIPP) can be the presenting clinical picture experienced by patients with secreting germ cell tumor (GCT). Indeed, as luteinizing hormone (LH) and human chorionic gonadotropin (hCG) share identical α-subunits and similar β-subunits, an increased secretion of β-hCG may result in a precocious activation of Leydig cells. Though the co-occurrence of raised β-hCG levels and signs of precocious virilization usually prompts a complete oncological work-up, the diagnostic and therapeutic management of GCT-induced GIPP may be challenging. We report the case of a 6.2 year-old boy presenting with clinical and biochemical findings consistent with GIPP (discrepancy between overt virilization and pre-pubertal testicular volume, suppressed gonadotropins and remarkably raised testosterone). Brain imaging detected a bilobed cyst of the pineal gland, while serum and cerebrospinal baseline assessment initially ruled out raised alpha-fetoprotein or β-hCG levels. Nevertheless, a strict biochemical follow-up highlighted a fluctuant trend of tumor markers, with a more aggressive behavior and recurrent erections occurring as a result of unpredictable phases of raised testosterone and serum/cerebrospinal β-hCG, followed by sudden spontaneous decrease. Accordingly, a secreting pineal GCT was suspected. Given the fluctuating trend of tumor markers, surgery was initially kept on hold and a combined treatment with bicalutamide (androgen receptor blocker) and anastrozole (aromatase inhibitor) was undertaken in order to prevent the patient from experiencing further virilization and excessive bone age maturation. Subsequently, a progression in the size of the pineal tumor prompted surgical resection and a diagnosis of secreting GCT was histologically confirmed. Accordingly, the patient was started on adjuvant chemo- and radiotherapy. Antineoplastic treatment was followed by persistent and remarkable decrease of tumor markers and by a complete pubertal arrest. We reported the challenging diagnosis of a secreting pineal GCT in a patient with GIPP and a fluctuating trend of tumor markers, testosterone levels and associated clinical signs, hence prompting the indication for a systematic assessment and a strict monitoring whenever a patient with GnRH-independent precocious puberty shows clinical or radiological markers potentially consistent with a GCT.

Abstract
The incidence of intracranial germ cell tumors (iGCT) is much lower in European and North American (E&NA) than in Asian population. However, E&NA cooperative groups have simultaneously developed with success treatment strategies with specific attention paid to long-term sequelae. Neurological sequelae may be reduced by establishing a diagnosis with an endoscopic biopsy and/or cerebrospinal fluid (CSF) and/or serum analysis, deferring the need to perform a radical surgery. Depending on markers and/or histological characteristics, patients are treated as either germinoma or non-germinomatous germ cell tumors (NGGCT). Metastatic disease is defined by a positive CSF cytology and/or distant drops in craniospinal MRI. The combination of surgery and/or chemotherapy and radiation therapy is tailored according to grouping and staging. With more than 90% 5-year event-free survival (EFS), localized germinomas can be managed without aggressive surgery, and benefit from chemotherapy followed by whole ventricular irradiation with local boost. Bifocal germinomas are treated as non-metastatic entities. Metastatic germinomas may be cured with craniospinal irradiation. With a 5-year EFS over 70%, NGGCT benefit from chemotherapy followed by delayed surgery in case of residual disease, and some form of radiotherapy. Future strategies will aim at decreasing long-term side effects while preserving high cure rates.

Molecular Pathology and Targeted Therapies for Personalized Management of Central Nervous System Germinoma. J Pers Med 2021; 11:jpm11070661.

Abstract
Intracranial germinomas are rare tumours, usually affecting male paediatric patients. They frequently develop in the pineal and suprasellar regions, causing endocrinological disturbances, visual deficits, and increased intracranial pressure. The diagnosis is established on magnetic resonance imaging (MRI), serum and cerebrospinal fluid (CSF) markers, and tumour stereotactic biopsy. Imaging techniques, such as susceptibility-weighted imaging (SWI), T2* (T2-star) gradient echo (GRE) or arterial spin labelling based perfusion-weighted MRI (ASL-PWI) facilitate the diagnosis. Germinomas are highly radiosensitive tumours, with survival rates >90% in the context of chemoradiotherapy. However, patients with resistant disease have limited therapeutic options and poor survival. The aim of this review is to highlight the genetic, epigenetic, and immunologic features, which could provide the basis for targeted therapy. Intracranial germinomas present genetic and epigenetic alterations (chromosomal aberrations, KIT, MAPK and PI3K pathways mutations, DNA hypomethylation, miRNA dysregulation) that may represent targets for therapy. Tyrosine kinase and mTOR inhibitors warrant further investigation in these cases. Immune markers, PD-1 (programmed cell death protein 1) and PD-L1 (programmed death-ligand 1), are expressed in germinomas, representing potential targets for immune checkpoint inhibitors. Resistant cases should benefit from a personalized management: genetic and immunological testing and enrolment in trials evaluating targeted therapies in intracranial germinomas.

Abstract
BACKGROUND To describe the various neuro-ophthalmic presentations, key exam features, and clinical findings associated with 5 common primary and secondary intracranial malignancies. EVIDENCE ACQUISITION Retrospective PubMed search and review of published case reports, case series, observational studies, book chapters, and review articles examining the neuro-ophthalmic features of intracranial malignancies including primary glial neoplasms (e.g., glioblastoma multiforme), primary and secondary lymphoma, intracranial metastases, carcinomatous/lymphomatous meningitis, and intracranial germ cell tumors. The search strategy used to perform the retrospective review included the aforementioned tumor type (e.g., glioblastoma multiforme) and the following terms and Boolean operators: AND ("visual loss" OR "papilledema" OR "diplopia" OR "ophthalmoplegia" or "neuro-ophthalmology" OR "proptosis"). RESULTS The rate of growth and the location of an intracranial tumor are essential factors in determining the neuro-ophthalmic presentation of certain intracranial malignancies. Primary malignant brain glial neoplasms commonly present with visual afferent complaints (e.g., unilateral or bilateral visual acuity or visual field defects, bitemporal or homonymous hemianopsia), pupil abnormalities (relative afferent pupillary defect), and optic atrophy or papilledema. Primary intraocular lymphoma (with or without central nervous system lymphoma) typically presents as a painless bilateral vitritis. Secondary intracranial malignancies have variable afferent and efferent visual pathway presentations. Carcinomatous/lymphomatous meningitis is associated with diplopia (e.g., multiple ocular motor cranial neuropathies with or without vision loss from papilledema or compressive/infiltrative optic neuropathy). Intracranial germ cell tumors can present with a chiasmal syndrome or dorsal midbrain syndrome. CONCLUSION Intracranial malignancies can present with neuro-ophthalmic symptoms or signs depending on topographical localization. Specific neuro-ophthalmic presentations are associated with different malignant intracranial tumors. Clinicians should be aware of the common malignant intracranial tumors and their associated clinical presentations in neuro-ophthalmology.

Abstract
Background: The goal of this retrospective study is to present the first epidemiological data on pediatric supratentorial central nervous system (CNS) tumors in Lebanon and to review the various surgical management strategies used. Methods: We conducted a retrospective case series of all pediatric patients who presented with a supratentorial CNS tumor and underwent surgery at our institution between 2006 and 2016. We collected and analyzed demographic characteristics, tumor location, clinical manifestations, histopathology, and surgical management strategies and outcome, and discussed them after dividing the tumors as per location and in view of published literature. Results: Ninety-nine children were studied with a male-to-female ratio of 2.3:1 and a mean age of 8.5 years. The most common location was convexity (44%) and included low-grade and high-grade glial tumors, along with other miscellaneous lesions. The next location was sellar/diencephalic (34%), including craniopharyngiomas, hypothalamic/optic pathway/thalamic gliomas, hamartomas, and pituitary/Rathke’s cyst, where there was notable use of endoscopic techniques (21%). Tumors in the pineal region (13%) were tectal gliomas, germ cell tumors, and pineoblastomas and were mostly treated endoscopically. The last group was lateral intraventricular tumors (8%) and was mostly choroid plexus lesions and ependymomas. Overall, the surgical objective was achieved in 95% with mild/moderate complications in 17%. Conclusion: A variety of pathologies may affect the pediatric population in the supratentorial region. Different surgical strategies, including microsurgical and endoscopic techniques, may be employed to remove, debulk, or biopsy these tumors depending on their location, suspected diagnosis, prognosis, and the need for treatment of possible associated hydrocephalus.

Abstract
Primary tumors of the pineal gland occur infrequently with a preponderance of either parenchymal tumors or germ cells tumors. Papillary tumor of the pineal region is a rare neuroepithelial lesion that arises exclusively in the pineal region. They have been designated as either Grade II or Grade III lesions as per the 2016 WHO classification of central nervous system tumors. Clinically, they usually present with obstructive hydrocephalus and visual disturbance. On imaging, these tumors are solid-cystic, heterogeneously enhancing, and show T2 hyperintensity. Pathologically, they can closely resemble a Grade I pineocytoma and immunohistochemistry is essential to differentiate the two. No definite guidelines exist to confirm the ideal protocol of treatment. Evidence regarding the role of radiation after surgery is limited to case reports and series. Adjuvant therapy is usually recommended for tumors with subtotal excision, high proliferative/mitotic index, or proven metastasis. We describe a case of a 29-year-old male with a recurrent papillary tumor of the pineal region, 9 years after primary surgery where it was misdiagnosed as a pineocytoma. The tumor was effectively controlled with surgical excision, cerebrospinal fluid diversion, and adjuvant radiation for 8 years before showing two recurrences within a span of 6 months with a rising proliferation index.

Abstract
BACKGROUND Germinoma is the most common type of germ cell tumor that develops intracranially. Germinomas usually grow in the midline structures, such as the pineal and suprasellar regions, and are rarely found in other locations. To the best of the authors’ knowledge, no previous research has reported on growth of this tumor in the cranial vault. OBSERVATIONS The authors reported an unusual case of primary cranial vault germinoma in a young adult. Macroscopically, the tumor had a solid-soft consistency and grayish color with brownish spots on the surface. The histological examination revealed anaplastic cells with round, hyperchromatic, pleomorphic nuclei; prominent nucleoli; and abundant, clear cytoplasm, arranged in lobules and sheets that were infiltrated by lymphocytes and separated by fibrous connective tissue. These findings were consistent with the histopathological characteristics of germinoma. LESSONS Primary cranial vault germinoma is a unique tumor because no previous research has reported any growth in that location. It should be considered one of the differential diagnoses of lesions located over the cranial vault. Histopathological examination is still the primary modality for diagnosing these tumors and excluding other differential diagnoses.

Abstract
Simple Summary Pineal neoplasms are tumors with different and variable morphological, histological, and radiological characteristics and, consequently different diagnosis and management. Due to their rarity, pineal tumors may be misdiagnosed. Pineal tumors, are divided into germ cell tumors, pineal parenchymal tumors and tumors that derive from adjacent structures. In this review, we report the clinical relevance of the main pineal gland tumors, underlining the importance of studying the triggering causes of pineal region carcinogenesis, to realize appropriate diagnosis and, consequently, better clinical management. Abstract The pineal gland is a small, pinecone-shaped endocrine gland that participates in the biological rhythm regulation of vertebrates. The recognized major product of the pineal gland is melatonin—a multifunctional endogenous indoleamine. Accumulating evidence suggests that the pineal gland is important for preserving ideal health conditions in vertebrate. Tumors of the pineal region account for approximately 3–11% of pediatric brain neoplasms but fewer than 1% of brain neoplasms in adults. It is fundamental to expand advanced imaging techniques together with both clinical and laboratory knowledge, to help to differentiate among pineal neoplasms and thus facilitate accurate primary diagnoses and proper therapeutic interventions. In this review, we report the gross anatomy of the pineal gland and its functional significance and discuss the clinical relevance of pineal gland tumors, underlining the importance of identifying the leading causes of pineal region masses.

The Third Eye Sees Double: Cohort Study of Clinical Presentation, Histology, Surgical Approaches, and Ophthalmic Outcomes in Pineal Region Germ Cell Tumors. World Neurosurg 2021; 150:e482-e490.

Abstract
BACKGROUND Intracranial germ cell tumors (GCTs) predominantly occur in the adolescent and young adult population and are most frequently located at the pineal gland. Tumor masses in the pineal region may cause ophthalmic symptoms due to compression to the midbrain, frequently presenting with Parinaud syndrome and hydrocephalus due to aqueductal compression. METHODS We conducted a single-institution cohort study of primary, pineal region GCTs to characterize the clinical presentation, as well as associated ophthalmic and hydrocephalus outcomes. RESULTS Fifty-six primary pineal GCTs were identified. Among the 40 isolated pineal region GCTs, 15 were germinomas while 25 were nongerminomatous GCTs. Among 43 cases of hydrocephalus, endoscopic third ventriculostomy was the primary treatment in 27 cases, which was successful in 23 but failed and required additional treatment for the rest. Pineal tumor mass was significantly larger in cases with hydrocephalus compared with those without, and the 20-mm diameter of the tumor was the crucial point for obstructive hydrocephalus. Ophthalmic symptoms were commonly observed at presentation, which included diplopia (74.3%), upward-gaze palsy (69.7%), and Argyll Robertson pupil (40%). These symptoms tended to remain, and the existence of these symptoms at presentation predicted the remaining symptoms in the follow-up. CONCLUSIONS Intracranial GCTs presenting with ophthalmic abnormalities appear to be at increased risk of residual posttreatment symptoms, while second-look surgery presents a significant risk factor for the development of new deficits. Hydrocephalus often accompanies pineal region GCTs, and in most cases both cerebrospinal fluid diversion and tissue diagnosis can be successfully achieved via endoscopic third ventriculostomy.

Abstract
OBJECTIVE Intracranial germ cell tumors (GCTs) are relatively rare neoplasms, representing 2-3 % of paediatric brain tumors in Western countries and 8-15 % in East Asia. Here, we discuss the clinical features and treatment outcomes in patients with central nervous system (CNS) GCTs treated at our institute. METHODS Medical records of all primary CNS GCT patients were retrieved retrospectively from 2007 to 2019. Demographic, clinical, treatment and follow up details were entered in a predesigned proforma. Overall survival (OS) and progression-free survival was computed using Kaplan-Meier method and Log-Rank test. Effect of various prognostic factors on survival outcomes was assessed by univariate and multivariate analysis. RESULTS A total of 28 CNS GCT patients were included in this analysis. Median age at presentation was 17 years (range, 7-45 years) with a male to female ratio of 1.8:1. Pineal region was the commonest location, encountered in 15 patients (53.6 %). Pure germinoma was the most frequent histology observed, seen in 19 patients (67.9 %). Male gender and germinoma histology were highly associated with pineal location (p = 0.043 and p = 0.052, respectively). Fourteen patients underwent surgical intervention and nine patients underwent biopsy for diagnostic purpose or to relieve the obstructive symptoms. Only 23 patients (82.1 %) received chemotherapy. However, all patients received radiotherapy (Craniospinal irradiation/whole brain radiotherapy/whole ventricular radiotherapy/ or local radiotherapy). After a median follow-up of 53 months (range, 7-150), 23 patients (82.1 %) were alive. OS was significantly affected by histology (89 % in germinoma vs. 60 % in non-germinomatous, p = 0.054) and location (93 % in pineal region vs. 64.2 % in other location, p = 0.042). Age, gender and surgery did not have any impact on the survival outcomes. CONCLUSION CNS GCTs are relatively rare and heterogeneous neoplasms commonly seen in pineal and suprasellar locations. A combination of chemotherapy and radiotherapy had shown excellent outcomes.

Abstract
An 18 year old patient was presented to the ophtalmology outpatient clinic with blurrred vision, headache and fatigue for 6 months. Ophtalmological examination showed loss of visual acuity in the left eye and decreased in the right eye and bilateral optic atrophy. Further physical examination pointed out delayed sexual development. Hypopituitarism was observed in endocrinological examination. Brain magnetic resonance imaging (MRI) demonstrated contrast enhancing mass lesion at suprasellar region with involvement of posterior perimesencephalic cisternal region. The mass resected by craniotomy and pathology showed germinoma. Afterwards he received systemic chemotherapy with bleomisin, etoposide, cisplatin for 4 cycles followed by cranial radiotherapy with 30.6 Gy with a boost to the primary tumor at a dose of 19.8 Gy. On his follow-up MRI, there are no signs of residual tumor nor tumor recurrence. His final examination reveals slightly increased visual acuity in the right eye and he continued to take hydrocortisone and L-thyroxin. After one year follow-up, human chorionic gonadotropin (hCG) alpha treatment was started for sexual development. Here in, we present a case with suprasellar germinoma in the context of the review of the literature.

Abstract
Pathologies involving the pituitary stalk (PS) are generally revealed by the presence of diabetes insipidus. The availability of MRI provides a major diagnostic contribution by enabling the visualization of the site of the culprit lesion, especially when it is small. However, when only an enlarged PS is found, the etiological workup may be difficult, particularly because the biopsy of the stalk is difficult, harmful and often not contributive. The pathological proof of the etiology thus needs to be obtained indirectly. The aim of this article was to provide an accurate review of the literature about PS enlargement in adults describing the differences between the numerous etiologies involved and consequent different diagnostic approaches. The etiological diagnostic procedure begins with the search for possible other lesions suggestive of histiocytosis, sarcoidosis, tuberculosis or other etiologies elsewhere in the body that could be more easily biopsied. We usually perform neck, thorax, abdomen, and pelvis CT scan; positron emission tomography scan; bone scan; or other imaging methods when we suspect generalized lesions. Measurement of serum markers such as human chorionic gonadotropin, alpha-fetoprotein, angiotensin converting enzyme, and IgG4 may also be helpful. Obviously, in the presence of an underlying carcinoma (particularly breast or bronchopulmonary), one must first consider a metastasis located in the PS. In the case of an isolated PS enlargement, simple monitoring, without histological proof, can be proposed (by repeating MRI at 3-6 months) with the hypothesis of a germinoma (particularly in a teenager or a young adult) that, by increasing in size, necessitates a biopsy. In contrast, a spontaneous diminution of the lesion is suggestive of infundibulo-neurohypophysitis. We prefer not to initiate steroid therapy to monitor the spontaneous course when a watch-and-see attitude is preferred. However, in many cases, the etiological diagnosis remains uncertain, requiring either close monitoring of the lesion or, in exceptional situations, trying to obtain definitive pathological evidence by a biopsy, which, unfortunately, is in most cases performed by the transcranial route. If a simple surveillance is chosen, it has to be very prolonged (annual surveillance). Indeed, progression of histiocytosis or germinoma may be delayed.

Toll SA, Jones MT, Yoshida EJ, Dhall G, Olch AJ, Wong KK. The relationship between ventricular volume and whole-brain irradiation dose in central nervous system germ cell tumors. Pediatr Blood Cancer 2019; 66:e28005. [PMID: 31535450 DOI: 10.1002/pbc.28005] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/24/2019] [Revised: 08/19/2019] [Accepted: 09/08/2019] [Indexed: 11/08/2022]
Abstract
BACKGROUND Advanced irradiation techniques, including intensity-modulated radiation therapy (IMRT), aim to limit irradiation to adjoining tissues by conforming beams to a well-defined volume. In intracranial germinomas, whole-ventricular IMRT decreases the volume of irradiation to surrounding parenchyma. This study examined the relationship between ventricular volume and radiation dose to surrounding tissue. PROCEDURE We retrospectively reviewed age, sex, ventricular and brain volume, ventricular dose, and volume of brain that received 12 Gy (V12) for patients diagnosed with germ cell tumors at our institution treated with whole-ventricular IMRT between 2002 and 2016. Variables were assessed for correlation and statistical significance. RESULTS Forty-seven patients were analyzed. The median whole-ventricular irradiation dose was 24 Gy with a median boost dose of 30 Gy. The median ventricular volume was 234.3 cm3 , and median brain volume was 1408 cm3 . There was no significant difference between mean ventricular volume of suprasellar versus pineal tumors (P = .95). The median V12 of the brain, including the ventricles, was 58.9%. The strongest correlation was between ventricular volume and V12, with an r2 (coefficient of determination) of .47 (P < .001). Multiple regression analysis indicated that total boost dose and boost planning target volume significantly predicted V12 (P < .001). CONCLUSIONS Although whole-ventricular IMRT limited irradiation to surrounding tissue in our cohort, a significant percentage of the brain received at least 12 Gy. This study suggests that there is a positive correlation between ventricular volume and the volume of brain parenchyma receiving at least 12 Gy with an important contribution from the boost phase of treatment.

Abstract
Background: Germ cell tumors (GCTs) represent approximately 3% of primary pediatric brain tumors in the West, whereas in Asia, they constitute between 8% and 15% of pediatric brain tumors. Methods: We retrospectively studied all patients with intracranial GCT managed at our institute from January 1998 to December 2013. The clinical data and radiological data were analyzed. Results: Forty-eight patients with intracranial GCT including 36 males and 16 females formed the cohort. The proportion of GCT in our study was 0.29%. The mean age was 16.5 ± 2.5 years. Germinomas constituted 56.3% and nongerminomatous GCTs constituted 43.7% of all the tumors. The most common location was posterior third ventricle (58.3%) followed by suprasellar (22.9%). Histopathological diagnosis was obtained in almost all patients (96%). Surgical procedures included tumor decompression (71.7%), stereotactic biopsy (13%), and endoscopic third ventriculostomy and biopsy (15%). Patient's age, location of the tumor, and histology did not influence the survival. Women with GCTs had poorer survival when compared to men. Conclusions: The present study documented a lower hospital-based incidence of GCT in Indian cohort. A multidisciplinary approach including surgical strategy based on location, appropriate radiation planning, and chemotherapy is needed for effective treatment and improved outcomes.

Abstract
Multimodal strategies have significantly improved the outcomes for patients with central nervous system nongerminomatous germ cell tumors. Two large cooperative group studies have recently reported much improved outcomes compared with historical series. However, a substantial proportion of patients still attain inadequate responses to initial chemotherapy prior to irradiation, with adverse impact upon survival; optimal induction chemotherapy regimens and radiotherapy strategies are as yet unidentified. Outcomes for patients with relapsed disease remain poor. There is an obvious need to incorporate molecular studies within prospective clinical trials that will likely lead to the incorporation of targeted, more effective future treatment strategies.

Abstract
Background: The pineal gland, a small, pinecone-shaped organ deep within the brain, is responsible for producing melatonin. The gland consists of pineal parenchymal cells and glial cells that can form neoplasms. Pineal region neoplasms can also arise from germ cells and adjacent structures. This review focuses on detection of serum and cerebrospinal fluid (CSF) biomarkers of germ cell tumors and pineal parenchymal cell tumors, as these types comprise most neoplasms specific to the pineal region. Methods: For this review, we searched PubMed using the following keywords: biomarkers, germ cell tumor, germinoma, melatonin, pineal, pineal gland, pineal neoplasm, pinealoma, pineal parenchymal cell tumor, pineal region, and pineal tumor. We limited our search to full-text English articles and identified other relevant sources from the reference lists of identified articles. Results: Serum and CSF biomarker assays have a role in cases of suspected pineal germ cell or parenchymal neoplasms. Biomarkers including alpha-fetoprotein, beta-human chorionic gonadotropin, and placental alkaline phosphatase inform diagnosis and treatment and are important for monitoring germ cell tumor response to treatment. No biomarkers are currently available that inform diagnosis or treatment of pineal parenchymal tumors, although melatonin assays may have a role in monitoring response to treatment. Conclusion: Serum and CSF biomarkers in conjunction with clinical and radiographic evidence of a pineal region mass can inform the decision whether to undertake stereotactic biopsy or surgical excision or whether to proceed straight to medical treatment.

Abstract
BACKGROUND Intracranial germinomas are uncommon and constitute less than 1% of all intracranial tumors. They usually arise in the midline of the brain, most commonly in the pineal region. Pineal germinomas tend to spread through the cerebrospinal fluid (CSF). However, pineal germinomas with fast-developing diffuse subarachnoid/leptomeningeal dissemination are extremely rare, especially in young children. METHODS The case of a 4-year-old boy with a pineal germinoma who died of diffuse subarachnoid/leptomeningeal dissemination 1 month after radiotherapy is reported. A PubMed search with specific key terms was used to review cases of pineal germinomas with metastasis. RESULTS The patient presented with a two-week history of worsening headache, visual disturbances and nonprojectile vomiting. Parinaud's sign was positive on physical examination. Head computed tomography (CT)/magnetic resonance imaging (MRI) revealed a lesion in the pineal region with eccentric calcification and obvious supratentorial hydrocephalus. Pineal germinoma was suspected. A ventriculoperitoneal (VP) shunt followed by focal radiotherapy ameliorated the headaches and visual disturbances. The patient was discharged home without further treatment due to financial difficulties. One month after discharge, he was readmitted due to worsening headache, vomiting and lethargy. MRI showed a decrease in the size of the pineal lesion but revealed a diffuse leptomeningeal enhancement including the sulcus, basal cistern, prepontine cistern, and supravermian cistern. The patient's condition deteriorated rapidly, and he died 26 hours after readmission. The characteristics of pineal germinomas with metastasis are reported based on a review of the literature. CONCLUSIONS Metastases in pineal germinomas predominately occur in adolescents or young adults, most commonly as spinal "drop metastases." Dissemination usually develops several years after the initial tumor diagnosis and has a relatively good clinical prognosis. However, fast widespread subarachnoid/leptomeningeal dissemination and sudden death may occur in a young child before salvage treatment, as in the presented case.

Abstract
BACKGROUND The pineal region tumors are surrounded by important structures. Neuroendoscopy has been increasingly used at home and abroad. This study is to simulate pure neuroendoscopic infratentorial supracerebellar approach for resection of pineal region tumor from the cadaveric head, and discuss the advantages and safety through this corridor. METHODS The anatomical structure for resection of pineal region tumor was visualized through pure neuroendoscopic infratentorial supracerebellar approach in three cadaveric heads. Three cases with pineal region tumors were retrospectively analyzed and summarized between June 2017 and December 2017. All cases were operated through pure neuroendoscopic infratentorial supracerebellar approach in the first affiliated hospital of Fujian medical university. RESULTS The anatomical structures of pineal region can be completely visualized by pure neuroendoscopic infratentorial supracerebellar corridor in the cadaveric head. Among the three cases, the first case was total resection, the second case was subtotal resection and the last case was partial resection. The postoperative pathology revealed cavernous hemangioma, germinoma and yolk sac tumor, respectively. The patients were followed-up for 1-6 months and had normal life.The KPS (karnofsky performance status) score was 100. CONCLUSION The anatomical structure of the pineal region can be completely visualized and the tumor can be safely removed through pure neuroendoscopic infratentorial supracerebellar approach.

Abstract
BACKGROUND Tumors within the pineal region represent 1.5 to 8.5% of the pediatric brain tumors and 1.2% of all brain tumors. A management algorithm has been proposed in several publications. The algorithm includes endoscopic third ventriculostomy (ETV) and biopsy in cases presenting with hydrocephalus. In this series, we are presenting the efficacy of a single-trajectory approach for both ETV and biopsy. METHODS Eleven cases were admitted to Alexandria main university hospital from 2013 to 2016 presenting with pineal region tumors and hydrocephalus. Mean age at diagnosis was 11 years (1-27 years). All cases had ETV and biopsy using rigid ventriculoscope through a single trajectory from a burr hole planned on preoperative imaging. Follow-up period was 7-48 months. RESULTS All 11 cases presented with hydrocephalus and increased intracranial pressure manifestations. Histopathological diagnosis was successful in 9 out of 11 cases (81.8%). Three cases were germ-cell tumors, two cases were pineoblastomas, two cases were pilocytic astrocytomas, and two cases were grade 2 tectal gliomas. Five of the ETV cases (45.5%) failed and required VPS later on. Other complications of ETV included one case of intraventricular hemorrhage and a case with tumor disseminated to the basal cisterns. CONCLUSION In our series, we were able to achieve ETV and biopsy through a single trajectory and a rigid endoscope with results comparable to other studies in the literature.

Abstract
BACKGROUND Germinomas are rare malignant central nervous system tumors, a type of germ cell tumor, according to the 2016 World Health Organization Classification of Brain Tumors. Most of these tumors develop along the midline, most often from the pineal gland, followed by tumors arising in the suprasellar cisterns. Suprasellar germinomas commonly manifest with diabetes insipidus, visual impairment, and hypothalamic-pituitary failure. We present a literature review from the PubMed database and report 2 cases of suprasellar germinomas. CASE DESCRIPTION Both pediatric patients presented with progressive visual loss; one did not show endocrinologic impairment, and the other presented with hypothyroidism, diabetes insipidus, and generalized edema. Magnetic resonance imaging showed expansive suprasellar masses in both cases, confirmed as germinomas at histopathologic examination. The patients were treated with the same surgical approach, although their outcomes were different because of endocrinologic and post surgical complications. CONCLUSIONS Suprasellar germinomas are highly curable lesions when diagnosed early. The treatment remains controversial and should be individualized, but the association of chemotherapy and radiotherapy allows reduce adverse effects and shows great results.

Abstract
BACKGROUND Pineoblastoma is a rare malignant tumor of the pineal gland, which is more common in children. METHODS We retrospectively reviewed 18 cases of pineoblastoma in children (10 girls), including general, clinical, and therapeutic information, and factors affecting prognosis. RESULTS The median age of the children was 51.7 months (range, 19-156 months). Presenting symptoms included vomiting (64.70%), headache (47.06%), weak or unsteady walking (35.29%), and nausea (29.41%). Rarer symptoms (1 patient each) included limb rigidity, inability to speak, double vision, fever, and Parinaud syndrome. Five and 13 children, respectively, underwent subtotal and gross total resection; 5 and 13 children received adjuvant craniospinal irradiation therapy and chemotherapy. Two children received both craniospinal irradiation and chemotherapy. The 5-year overall survival of the patients was 27.8% (5/18). The survival rate of children older than 4 years (66.7%) was significantly higher than that of younger children (8.3%). The 5-year overall survival rate of boys (50.7%) was higher than that of girls (10.0%); that of children who underwent gross total resection (30.8%) was higher than that of children who underwent subtotal resection (20.0%); and that of children treated with adjuvant craniospinal irradiation (50.7%) was higher than that of those not given craniospinal irradiation (10.0%). However, in each of these 3 comparisons the differences were not significant. CONCLUSION Pineoblastoma is rare but often fatal, especially in children younger than 4 years. Survival rates tend to be higher in boys, children undergoing gross total resection (rather than subtotal), and those given craniospinal irradiation.

Abstract
IMPORTANCE Primary central nervous system (CNS) germ cell tumors (GCT) are a heterogeneous group of tumors that are still poorly understood. In North America, GCTs comprise approximately 1% of primary brain tumors in pediatric and young adult patients. GCTs can occur as pure or mixed subtypes; they are divided into germinomas, which are the most common subtype, and non-germinomatous germ cell tumors (NGGCTs), which consist of approximately one-third of GCTs and include teratomas, embryonal carcinomas, choriocarcinomas, and yolk sac tumors. OBSERVATIONS While the etiology of primary CNS GCT is not entirely clear, the various subtypes are lineage-related and may involve progenitor germ cells that fail to migrate and become trapped in midline locations. Primary CNS GCT most commonly arises in the pineal region but also occur in other areas. Presenting symptoms can include headache, Parinaud syndrome, diabetes insipidus, precosious puberty, ataxia, or hemiparesis. Diagnosis of primary CNS GCTs can be difficult and is often delayed. Various imaging studies and tumor markers can assist in specific diagnosis. Treatment plans differ depending on the subtype of GCT and may vary among physicians and institutions. Germinomas have a favorable prognosis with a greater than 90% overall survival, while NGGCTs only have survival rates ranging from 40-70%. CONCLUSIONS AND RELEVANCE Germinomas seem to be most effectively treated with chemotherapy and radiation, while NGGCT usually require surgical resection, chemotherapy, and radiation with the exception of mature teratomas frequently curable with surgery alone. Gamma knife radiosurgery is a promising treatment that may be an effective additional treatment option. Cytogenic and molecular analyses are attempting to further specify the different GCT subtypes and are helping to direct the development of distinct therapeutic targets to improve treatment and prognosis.

Abstract
The goal of the study is to examine the practice pattern and survival outcome of adult and pediatric patients with intracranial germinoma. Patients from the National Cancer Database (NCDB) brain tumor registry between the years 2004-2014 with intracranial germinoma were extracted for analysis. Patients who had distant metastasis, received no treatments, or only surgery/chemotherapy alone were excluded. An age cutoff of > 21 years old was used to define the pediatric population. Patients were stratified by the treatments radiation therapy alone (RT) and chemotherapy followed by radiation therapy (C + RT). 445 patients with intracranial germinoma meeting our inclusion criteria were identified. Of the adult patients, 65.7% received RT and 34.3% received C + RT, compared to the pediatric patients, where 31.8% received RT and 68.2% received C + RT. Those patients who received C + RT had a lower radiation dose compared to the RT group (p < 0.001). The 5 and 10 year overall survival (OS) for the entire cohort was 92.6 and 87.9%, respectively. Univariate analysis demonstrated improved OS with younger age, private insurance, C + RT treatment, and pediatric patients. Only age and insurance type remained significant on multivariate analysis. The 5 year OS was 92.6% (RT) versus 97.2% (C + RT) (p = 0.307) and 83.4% (RT) versus 95.4% (C + RT) (p = 0.122) in the pediatric and adult patients, respectively. There is a higher use of C + RT with an accompanied reduction in RT dose in the treatment of intracranial germinoma. There is no difference in survival between the treatment approaches of RT or C + RT in the NCDB patient cohort.

Abstract
Abstract
The skull base is a complex anatomical region that harbors many important neurovascular structures in a relatively confined space. The pathology that can develop at this site is varied, and many disease processes may present with similar clinical and neuroimaging findings. While computed tomography maintains a role in the evaluation of many entities and can, for instance, delineate osseous erosion with great detail and characterize calcified tumor matrices, magnetic resonance imaging (MRI) is the mainstay in the neuroimaging assessment of most pathology occurring at the skull base. Various MRI sequences have proven to be robust tools for tissue characterization and can provide information on the presence of lipids, paramagnetic and diamagnetic elements, and tumor cellularity, among others. In addition, currently available MRI techniques are able to generate high spatial resolution images that allow visualization of cranial nerves and their involvement by adjacent pathology. The information obtained from such examinations may aid in the distinction of these disease processes and in the accurate delineation of their extent prior to biopsy or treatment planning.

Abstract
OBJECTIVE Central nervous system germ cell tumors (CNS GCTs) are relatively rare neoplasms. Incidence of CNS GCTs in Western literature is low (0.3-0.6 %) as compared to East Asia (3-4 %). No large study is available on CNS GCTs from India. METHODS Intracranial GCT cases were retrieved from databases of three tertiary care institutes in India; clinicopathological data was reviewed. RESULTS Ninety-five intracranial GCT cases were identified, accounting for 0.43 % of CNS tumors. Median age was 12 years (range, birth to 48 years); male preponderance was noted (66 %). Most patients (86.3 %) were aged <18 years. Pineal location was most common (45 %) and was associated with male gender and age >14 years. Germinoma was the commonest histopathological type (63.2 %), followed by teratoma (20 %). Suprasellar location was associated with germinoma histology. Follow-up was available for 71 patients (median, 15 months). Of these, 48 received adjuvant chemotherapy and/or radiotherapy. At the last follow-up, 44 patients showed no evidence of disease. Age >10 years, male gender, pineal location, and germinoma histology were associated with favorable outcome. CONCLUSION This is the first multicentric study from India establishing that incidence of CNS GCT in India is similar to that in the West and differs from that in East Asian countries. However, similar to both, germinoma is the commonest histological type, and pineal location is most frequent. Studies on molecular alterations based on ethnicity and geographical location are necessary to provide clarity on differences in incidence. Attention needs to be focused on decreasing treatment heterogeneity and minimizing treatment-related morbidity and mortality, improving the cure rate of these highly treatable tumors.

Abstract
The spectrum of pituitary stalk (PS) pathology is vast, presenting a diagnostic challenge. Published large series of PS lesions demonstrate neoplastic conditions are most frequent, followed by inflammatory, infectious and congenital diseases. Inflammatory pathologies however, account for the majority of PS lesions in published small case series and case reports. Physicians must be familiar with the major differential diagnoses and necessary investigations. A comprehensive history and thorough clinical examination is critical. Although magnetic resonance imaging of the PS in disease is nonspecific, associated intracranial features may narrow the differential diagnosis. Initial investigations include basic pathology and computer tomography imaging of the neck, chest, abdomen and pelvis. Further investigations should be guided by the clinical context. PS biopsy should be considered when a diagnosis is regarded essential in centres where an experienced neurosurgeon is available. Treatment is dependent on the underlying disease process and may necessitate pituitary hormone replacement.
