Abstract
Purpose The impact of delayed diagnosis on tumor-related prognosis appears to be minimal in individuals with intracranial germ cell tumors (iGCTs). However, its effect on neuroendocrine functions remains unclear. We aimed to assess the effects of delayed diagnosis on neuroendocrine function in individuals with suprasellar GCTs. Methods We conducted a retrospective cohort study of 459 individuals with suprasellar GCTs and categorized them into two groups based on disease duration: delayed diagnosis (> 6 months) and non-delayed diagnosis (≤ 6 months). We compared endocrinological symptoms, neuroendocrine dysfunction and its grading (categorized into 0-3 grades based on severity), and recovery from neuroendocrine dysfunction in both groups. Results Patients with delayed diagnosis exhibited higher incidences of amenorrhea, slow growth, fatigue, and polyuria/polydipsia. Neuroendocrine dysfunction, including central adrenal insufficiency (CAI), central hypothyroidism (CHT), arginine vasopressin deficiency (AVP-D), growth hormone deficiency, hypogonadism, and hyperprolactinemia, was more pronounced in the delayed diagnosis group at diagnosis, the end of treatment, and the last follow-up. Furthermore, individuals with delayed diagnosis showed higher grades of neuroendocrine dysfunction at diagnosis (OR=3.005, 95% CI 1.929-4.845, p<0.001), end of oncologic treatment (OR=4.802, 95% CI 2.878-8.004, p<0.001), and last follow-up(OR=2.335, 95% CI 1.307-4.170, p=0.005) after adjusting for confounders. Finally, less recovery, particularly in CAI, CHT, and AVP-D, was seen among the group with delayed diagnosis after treatment. Conclusion Among individuals with suprasellar GCTs, delayed diagnosis is associated with increased, more severe, and less recovered neuroendocrine dysfunction, emphasizing the importance of early diagnosis and treatment to reduce neuroendocrine dysfunction.

Abstract
The development of remote surgery hinges on comprehending the mechanical properties of the tissue at the surgical site. Understanding the mechanical behavior of the medulla oblongata tissue is instrumental for precisely determining the remote surgery implementation site. Additionally, exploring this tissue's response under electric fields can inform the creation of electrical stimulation therapy regimens. This could potentially reduce the extent of medulla oblongata tissue damage from mechanical compression. Various types of pulsed electric fields were integrated into a custom-built indentation device for this study. Experimental findings suggested that applying pulsed electric fields amplified the shear modulus of the medulla oblongata tissue. In the electric field, the elasticity and viscosity of the tissue increased. The most significant influence was noted from the low-frequency pulsed electric field, while the burst pulsed electric field had a minimal impact. At the microstructural scale, the application of an electric field led to the concentration of myelin in areas distant from the surface layer in the medulla oblongata, and the orderly structure of proteoglycans became disordered. The alterations observed in the myelin and proteoglycans under an electric field were considered to be the fundamental causes of the changes in the mechanical behavior of the medulla oblongata tissue. Moreover, cell polarization and extracellular matrix cavitation were observed, with transmission electron microscopy results pointing to laminar separation within the myelin at the ultrastructure scale. This study thoroughly explored the impact of electric field application on the mechanical behavior and microstructure of the medulla oblongata tissue, delving into the underlying mechanisms. This investigation delved into the changes and mechanisms in the mechanical behavior and microstructure of medulla oblongata tissue under the influence of electric fields. Furthermore, this study could serve as a reference for the development of electrical stimulation regimens in the central nervous system. The acquired mechanical behavior data could provide valuable baseline information to aid in the evolution of remote surgery techniques involving the medulla oblongata tissue.

[PMID: 38091701 DOI: 10.1016/j.clineuro.2023.108081] [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: 11/09/2023] [Accepted: 12/06/2023] [Indexed: 02/04/2024]
Abstract
BACKGROUND The prognostic role of lactate dehydrogenase (LDH) has been confirmed in many malignant tumors, but the role of serum LDH in primary central nervous system germ cell tumor (GCT) remains unknown. This study aimed to assess the prognostic value of LDH in GCT patients and develop a nomogram to predict prognosis in patients undergoing chemoradiotherapy. METHODS A total of 161 patients with GCT were included in this study. Using a restricted cubic spline (RCS) model, the optimal cutoff point for LDH was determined to be 217 U/L. The survival of GCT patients was evaluated using the Kaplan-Meier method and log-rank test to analyze the effects of LDH levels. Univariate Cox regression, multivariate Cox regression, and LASSO Cox regression were conducted to identify prognostic factors, which were incorporated into a nomogram for predicting overall survival (OS). The predictive accuracy of the nomogram was assessed using the C-index, calibration curve, area under the time-dependent receiver operating characteristic curve (time-dependent AUC), and risk group stratification. The net benefits of the nomogram at different threshold probabilities were quantified using decision curve analysis (DCA). RESULTS The high-LDH group had significantly shorter OS compared to the low-LDH group (P = 0.016). Based on the SYSUCC cohort, three variables were shown to be significant factors for OS and were incorporated in the nomogram: LDH, histopathology, and dissemination. It showed good discrimination ability, with C-index of 0.789 (95% CI, 0.671-0.907). Additionally, the clinical usefulness of the nomogram was confirmed by calibration curves and time-dependent AUC. DCA further highlighted the potential of the nomogram to guide clinical treatment strategies for patients. Moreover, there was a significant difference in OS among patients categorized into different risk groups (P < 0.001). CONCLUSION LDH levels may serve as a reliable predictor for assessing the therapeutic effect of chemoradiotherapy in GCT. The developed nomogram exhibits high accuracy in predicting survival outcomes, aiding in the classification of prognostic groups, and supporting informed clinical decision-making.

Abstract
Intracranial germ cell tumors (iGCTs) are rare malignant neoplasms that mainly affect children and adolescents. The incidence, clinical presentation, and prognosis of iGCTs exhibit high heterogeneity. Previous studies have primarily focused on eliminating tumors, reducing tumor recurrence, and improving survival rates, while neglecting the impact of the tumors and their treatment on neuroendocrine function. Throughout the entire course of the disease, neuroendocrine dysfunction may occur and is frequently overlooked by oncologists, neurosurgeons, and radiologists. Endocrinologists, however, are more interested in this issue and have varying priorities at different stages of the disease. From onset to the diagnostic phase, most patients with iGCTs may present with symptoms related to impaired neuroendocrine function, or even experience these symptoms as their first indication of the condition. Particularly, a minority of patients with sellar/suprasellar lesions may exhibit typical imaging features and elevated tumor markers long after the onset of initial symptoms. This can further complicate the diagnosis process. During the peritumor treatment phase, the neuroendocrine function shows dynamic changes and needs to be evaluated dynamically. Once diabetes insipidus and dysfunction of the hypothalamic-pituitary-adrenal and hypothalamic-pituitary-thyroid axes occur, hormone replacement therapy should be administered promptly to ensure successful tumor treatment for the patient. Subsequently, during the long-term management phase after the completion of tumor treatment, the evaluation of growth and development as well as corresponding hormone replacement therapy are the most concerning and complex issues. Thus, this paper reviews the interest of endocrinologists in iGCTs at different stages.

Abstract
INTRODUCTION Pineal region tumors (PRTs) are tumors arising from the pineal gland and the paraspinal structures. These tumors are rare and heterogeneous that account for 2.8-10.1% and 0.6-3.2% of tumors in children and in all ages, respectively. Almost all types and subtypes of CNS tumors may be diagnosed in this region. These tumors come from cells of the pineal gland (pinealocytes and neuroglial cells), ectopic primordial germ cells (PGC), and cells from adjacent structures. Hence, PRTs are consisted of pineal parenchyma tumors (PPTs), germ cell tumors (GCTs), neuroepithelial tumors (NETs), other miscellaneous types of tumors, cystic tumors (epidermoid, dermoid), and pineal cyst in addition. The symptoms of PRTs correlate to the increased intracranial cranial pressure due to obstructive hydrocephalus and dorsal midbrain compression. The diagnostic imaging studies are mainly MRI of brain (with and without gadolinium) along with a sagittal view of whole spine. Serum and/or CSF AFP/β-HCG helps to identify GCTs. The treatment of PRTs is consisted of the selection of surgical biopsy/resection, handling of hydrocephalus, neoadjuvant and/or adjuvant therapy according to age, tumor location, histopathological/molecular classification, grading of tumors, staging, and threshold value of markers (for GCTs) in addition. METHODS In this article, we review the following focus points: 1. Background of pineal region tumors. 2. Pineal GCTs and evolution of management. 3. Molecular study for GCTs and pineal parenchymal tumors. 4. Review of surgical approaches to the pineal region. 5. Contribution of endoscopy. 6. Adjuvant therapy (chemotherapy, radiotherapy, and combination). 7. FUTURE DIRECTION RESULTS In all ages, the leading three types of PRTs in western countries were PPTs (22.7-34.8%), GCTs (27.3-34.4%), and NETs (17.2-28%). In children and young adults, the leading PRTs were invariably in the order of GCTs (40-80.5%), PPTs (7.6-21.6%), NETs (2.4-37.5%). Surgical biopsy/resection of PRTs is important for precision diagnosis and therapy. Safe resection with acceptable low mortality and morbidity was achieved after 1970s because of the advancement of surgical approaches, CSF shunt and valve system, microscopic and endoscopic surgery. Following histopathological diagnosis and classification of types and subtypes of PRTs, in PPTs, through molecular profiling, four molecular groups of pineoblastoma (PB) and their oncogenic driver were identified. Hence, molecular stratified precision therapy can be achieved. CONCLUSION Modern endoscopic and microsurgical approaches help to achieve precise histopathological diagnosis and molecular classification of different types and subtypes of pineal region tumors for risk-stratified optimal, effective, and protective therapy. In the future, molecular analysis of biospecimen (CSF and blood) along with AI radiomics on tumor imaging integrating clinical and bioinformation may help for personalized and risk-stratified management of patients with pineal region tumors.

Abstract
Lhermitte-Duclos disease (LDD), or dysplastic cerebellar gangliocytoma, is a rare benign tumor characterized by unilateral hemispheric cerebellar expansion. It is linked to mutations in the phosphatase and tensin homolog (PTEN) gene, which inhibit the phosphatidylinositol-3'-kinase pathway, leading to increased cell division and defective neuronal migration. This study aims to compare the clinical, radiological, histopathological, surgical resolution, and follow-up characteristics of reported cases of this rare condition. An in-depth search of LDD patients' clinical records at our institute between 2003 and 2023 was conducted, in addition to a systematic literature review on PubMed. Three patients with a diagnosis of LDD were found. Cerebellar abnormalities, varying headaches, and visual impairment were all present clinically. On T2 in the posterior fossa, all three MRI scans displayed the typical hyperintense parallel streak appearance. The histopathological report showed that large ganglion cells had replaced the granular layer, Purkinje cells had degenerated, the molecular layer had become hyper-myelinated, and synaptophysin and chromogranin were positive. Partial tumor resection and avoiding intracranial hypertension were the main goals of treatment. Genetic follow-up was conducted for all three patients. Neurosurgeons must be aware of LDD to provide close genetic monitoring despite the benign nature of the tumor because of its link to Cowden syndrome and elevated risk of cancer in other organs.

Abstract
Sellar/suprasellar tumors comprise about 10% of all pediatric Central Nervous System (CNS) tumors and include a wide variety of entities, with different cellular origins and distinctive histological and radiological findings, demanding customized neuroimaging protocols for appropriate diagnosis and management. The 5th edition of the World Health Organization (WHO) classification of CNS tumors unprecedently incorporated both histologic and molecular alterations into a common diagnostic framework, with a great impact in tumor classification and grading. Based on the current understanding of the clinical, molecular, and morphological features of CNS neoplasms, there have been additions of new tumor types and modifications of existing ones in the latest WHO tumor classification. In the specific case of sellar/suprasellar tumors, changes include for example separation of adamantinomatous and papillary craniopharyngiomas, now classified as distinct tumor types. Nevertheless, although the current molecular landscape is the fundamental driving force to the new WHO CNS tumor classification, the imaging profile of sellar/suprasellar tumors remains largely unexplored, particularly in the pediatric population. In this review, we aim to provide an essential pathological update to better understand the way sellar/suprasellar tumors are currently classified, with a focus on the pediatric population. Furthermore, we intend to present the neuroimaging features that may assist in the differential diagnosis, surgical planning, adjuvant/neoadjuvant therapy, and follow-up of this group of tumors in children.

Abstract
The pathological diagnosis of intracranial germinoma (IG), oligodendroglioma, and low-grade astrocytoma on intraoperative frozen section (IFS) and hematoxylin-eosin (HE)-staining section directly determines patients' treatment options, but it is a difficult task for pathologists. We aimed to investigate whether whole-slide imaging (WSI)-based deep learning can contribute new precision to the diagnosis of IG, oligodendroglioma, and low-grade astrocytoma. Two types of WSIs (500 IFSs and 832 HE-staining sections) were collected from 379 patients at multiple medical centers. Patients at Center 1 were split into the training, testing, and internal validation sets (3:1:1), while the other centers were the external validation sets. First, we subdivided WSIs into small tiles and selected tissue tiles using a tissue tile selection model. Then a tile-level classification model was established, and the majority voting method was used to determine the final diagnoses. Color jitter was applied to the tiles so that the deep learning (DL) models could adapt to the variations in the staining. Last, we investigated the effectiveness of model assistance. The internal validation accuracies of the IFS and HE models were 93.9% and 95.3%, respectively. The external validation accuracies of the IFS and HE models were 82.0% and 76.9%, respectively. Furthermore, the IFS and HE models can predict Ki-67 positive cell areas with R2 of 0.81 and 0.86, respectively. With model assistance, the IFS and HE diagnosis accuracy of pathologists improved from 54.6%-69.7% and 53.5%-83.7% to 87.9%-93.9% and 86.0%-90.7%, respectively. Both the IFS model and the HE model can differentiate the three tumors, predict the expression of Ki-67, and improve the diagnostic accuracy of pathologists. The use of our model can assist clinicians in providing patients with optimal and timely treatment options.

Abstract
Primary central nervous system germ cell tumors (CNS GCTs) are part of the GCTs in children and adults. This tumor entity presents with geographic variation, age, and sex predilection. There are two age peaks of incidence distribution at the first few months of life and in adolescence. CNS GCTs are heterogeneous in histopathological subtypes, locations, and tumor marker (AFP, β-hCG) secretions. In the WHO CNS tumor classification, GCTS are classified as germinoma and nongerminomatous GCT (NGGCT) with different subtypes (including teratoma). Excluding mature teratoma, the remaining NGGCTs are malignant (NGMGCT). In teratoma, growing teratoma syndrome and teratoma with somatic-type malignancy should be highlighted. The common intracranial locations are pineal region, neurohypophysis (NH), bifocal pineal-NH, basal ganglia, and cerebral ventricle. Above 50% of intracranial GCTs (IGCTs) present obstructive hydrocephalus. Spinal tumors are rare. Age, locations, hydrocephalus, and serum/CSF titer of β-hCG correlate with clinical manifestations. Delayed diagnosis is common in tumors arising in neurohypophysis, bifocal, and basal ganglia resulting in the increasing of physical dysfunction and hormonal deficits. Staging work-up includes CSF cytology for tumor cells and contrast-enhanced MRI of brain and spine for macroscopic metastasis before treatment commences. The therapeutic approach of CNS GCTs integrates locations, histopathology, staging, tumor marker level, and therapeutic classification. Treatment strategies include surgical biopsy/excision, chemotherapy, radiotherapy (single or combination). Secreting tumors with consistent imaging may not require histopathological diagnosis. Primary germinomas are highly radiosensitive and the therapeutic aim is to maintain high survival rate using optimal radiotherapy regimen with/without chemotherapy combination. Primary NGNGCTs are less radiosensitive. The therapeutic aim is to increase survival utilizing more intensive chemotherapy and radiotherapy. The negative prognostic factors are residue disease at the end of treatment and serum or CSF AFP level >1000 ng/mL at diagnosis. In refractory or recurrent NMGGCTs, besides high-dose chemotherapy, new therapy is necessary. Molecular profiling and analysis help for translational research. Survivors of pediatric brain tumors frequently experience cancer-related cognitive dysfunction, physical disability, pituitary hormone deficiency, and other CNS complications after cranial radiotherapy. Continuous surveillance and assessment may lead to improvements in treatment protocols, transdisciplinary interventions, after-treatment rehabilitation, and quality of life.

Bifocal lesions have a poorer treatment outcome than a single lesion in adult patients with intracranial germinoma. PLoS One 2022; 17:e0264641. [PMID: 35231071 PMCID: PMC8887760 DOI: 10.1371/journal.pone.0264641] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2021] [Accepted: 02/14/2022] [Indexed: 11/18/2022] Open
Abstract
Intracranial germinoma (IG) rarely occurs in adults. Its optimal treatment strategy is unclear. We evaluated the outcomes of radiotherapy in adults with intracranial germinoma. Data of 29 adult patients (age, 18–52 years; median age, 24.3 years) with IG treated with radiotherapy at Taipei Veterans General Hospital were retrospectively reviewed. They were followed up for a median time of 5.9 years (range, 1.0–12.8 years). We used the Kaplan–Meier method to estimate the progression-free survival (PFS) and overall survival (OS), and univariate and multivariate Cox proportional hazards regression models to identify the factors affecting PFS. PFS and OS were compared between adult and pediatric patients with IG. The 1-, 3-, and 5-year PFS rates were 96.6%, 85.8%, and 77.8%, respectively, in the adult patients, and the OS rate were all 100%. Seven patients (24.1%) experienced recurrence, and in six of them, salvage therapy successfully controlled the disease. Two patients (6.9%) died after 5 years of follow-up due to disease progression and central pontine myelinolysis. In the univariate and multivariate Cox analysis, bifocal lesions had a significantly lower PFS than those with single lesions (p = 0.008). Kaplan–Meier survival analysis showed that adult patients had a poorer PFS (p = 0.06) and OS (p = 0.025) than pediatric patients. Our study showed bifocal lesions were associated with lower PFS than a single lesion among adult IG patients, and adult IG patients tended to have poorer PFS and OS compared to pediatric IG patients. For adult patients with bifocal IG, we recommend treatment with craniospinal irradiation, whole ventricle irradiation (WVI) with chemotherapy, or frequent spine images follow-up for patients who received only WVI.

Abstract
A fourteen-year-old boy initially presented with weakness in the right extremity, worsening in the last three months with stiffness and convulsions in his right extremity. Magnetic resonance imaging of the brain revealed an intra-axial tumor measuring 8.3x7.3x6.8 cm, leading to obstructive hydrocephalus. The patient's condition suddenly worsened with decreased consciousness, and then emergency surgery was performed for tumor resection and external ventricular drainage before switching to a ventriculoperitoneal shunt on the fifth day after surgery. Histopathological examination revealed a germinoma, which is rare in the thalamic region. The patient responded well to radiation therapy after surgery. Ectopic GCT may be difficult to differentiate on radiological examination alone. The current case was initially diagnosed as a high-grade glioma based on radiological findings. A definite diagnosis can be made only after a histopathological examination, which requires a tissue sample. Therefore, many tumors are surgically excised for biopsy purposes A good preoperative examination is very important to determine the approach to patient management. Furthermore, radiotherapy is mandatory for germinoma because of its radiosensitivity.

Abstract
BACKGROUND This multinational study was conducted to report clinical presentations and treatment strategies in patients with intracranial germinomas across selected Asian centers, including failure patterns, risk factors, and outcomes. METHODS A retrospective data collection and analysis of these patients, treated between 1995 and 2015 from eight healthcare institutions across four countries was undertaken. RESULTS From the results, 418 patients were analyzed, with a median follow-up of 8.9 years; 79.9% of the patients were M0, and 87.6% had β-human chorionic gonadotropin values <50 mIU/mL. The 5/10-year overall survival (OS) and recurrence-free survival (RFS) rates were 97.2%/96.2% and 89.9%/86.9%, respectively. RFS was predicted by the radiotherapy (RT) field, with focal RT having the worst outcome, whereas chemotherapy usage had no impact on survival. Among patients who received chemotherapy, response to chemotherapy did not predict survival outcomes. In M0 patients, primary basal ganglia tumors predicted a worse RFS. In patients with bifocal tumors, an extended field RT was associated with better outcomes. In multivariable analysis, only RT fields were associated with RFS. In relapsed patients, salvage rates were high at 85.7%. Additionally, patients who received salvage RT had a better outcome (91.6% vs. 66.7%). CONCLUSIONS Survival outcomes of patients with germinoma were excellent. Thus, the focus of treatment for intracranial germinoma should be on survivorship. Further studies are warranted to find the optimal intensity and volume of radiation, including the role of chemotherapy in the survival of patients with intracranial germinomas, considering age, primary tumor location, and extent of disease.

Abstract
OBJECTIVES To evaluate the subtype imaging features of basal ganglia germ cell tumors (GCTs). METHODS Clinical and imaging data of 33 basal ganglia GCTs were retrospectively analyzed, including 17 germinomas and 16 mixed germ cell tumors (MGCTs). RESULTS The cyst/mass ratio of germinomas (0.53 ± 0.32) was higher than that of MGCTs (0.28 ± 0.19, p = 0.030). CT density of the solid part of germinomas (41.47 ± 5.22 Hu) was significantly higher than that of MGCTs (33.64 ± 3.75 Hu, p < 0.001), while apparent diffusion coefficients (ADC, ×10-3 mm2/s) value of the solid part was significantly lower in geminomas (0.86 ± 0.27 ×10-3 mm2/s) than in MGCTs (1.42 ± 0.39 ×10-3 mm2/s, p < 0.001). MGCTs were more common with intratumoral hemorrhage (68.75% vs 11.76%, p = 0.01), T1 hyperintense foci (68.75% vs 5.88%, p < 0.001) and calcification (64.29% vs 20.00%, p = 0.025) than germinomas. There was no significant difference in internal capsule involvement between the two subtypes (p = 0.303), but Wallerian degeneration was more common in germinomas than in MGCTs (70.59% vs 25.00%, p = 0.015). CONCLUSION The subtypes of GCT have different imaging features. Tumoral cystic-solidity, heterogeneity, ADC value, CT density, and Wallerian degeneration are helpful to differentiate germinomas and MGCTs in basal ganglia. ADVANCES IN KNOWLEDGE The subtypes of GCT have different histological characteristics, leading to various imaging findings. The imaging features of GCT subtypes in basal ganglia may aid clinical diagnosis and treatment.

Abstract
Intracranial germ cell tumors (GCTs) account for 3%-5% of all intracranial tumors. They commonly manifest during first two decades of life. We are reporting a case of a young female, who presented with progressive visual loss, polyuria and polydipsia, harboring an intracranial GCT. She presented initially to a neurosurgery clinic and then to an endocrine clinic, with a history of chronic worsening headache and recent onset visual blurring along with polyuria with polydipsia. On further inquiry, she was found to have primary amenorrhea, easy fatigability, and failure of development of secondary sexual characteristics. On examination the patient had bitemporal hemianopia with breast development at tanner stage II and pubic and axillary hair at tanner stage I. Her initial hormonal workup was suggestive of panhypopituitarism with diabetes insipidus. MRI pituitary showed a sellar mass with suprasellar extension, so an initial impression of a pituitary macroadenoma was made and the patient underwent trans-sphenoidal surgery. The histopathology was suggestive of lymphoid hyperplasia. Follow up MRI showed significant residual tumor and her vision and pituitary function did not recover. Neurosurgery was planned as second surgery, but we requested a second opinion of histopathology report and it was suggestive of a germinoma. She was then started on chemotherapy followed by radiotherapy, after which her tumor size reduced significantly, though she still required pituitary hormone replacement therapy. Pituitary stalk lesions are rare and their diagnosis is challenging as different etiologies present clinically and radiologically in a similar manner with tissue diagnosis being the gold standard. Germinoma is a radiosensitive tumor. In our patient it took a long time to reach the correct diagnosis and late diagnosis resulted in permanent visual field defect and panhypopituitarism. This case report emphasizes that we should guide and educate our patients to seek medical advice early in the course of disease. We should also keep differential diagnosis in mind before referring the patient for surgery.

Abstract
PURPOSE To analyze neuro-ophthalmology symptoms in patients with germinomas located in pineal and suprasellar regions. MATERIAL AND METHODS The study analyzed 133 patients with germinoma who were receiving treatment in Burdenko Neuro-surgical Institute from 2008 to 2017. Assessment of results was performed by neuro-ophthalmology examination, a computerized oculograph was used for the objectification of the severity of ocular-motor and pupillary disorders. RESULTS Among the patients of the study, 65 had pineal germinoma, 42 - suprasellar germinoma and 26 - bifocal germinoma. Among patients with pineal germinomas, males prevailed, while more females had suprasellar germinomas. No statistical difference was found between gender and bifocal germinoma. Pineal germinomas were manifested predominantly by the development of the dorsal midbrain syndrome in the form of oculomotor and pupillary dysfunction (75%) and the development of papilledema (53%). Germinomas of suprasellar localization are most often presented by asymmetric chiasmatic syndrome (24%). Dorsal midbrain syndrome in patients with bifocal germinomas was detected in 76% cases, combination of oculomotor and pupillary dysfunction with visual impairments was found in 38% cases. Neuro-ophthalmological symptoms of germinoma of these regions manifest in the early stages of the disease and require ophthalmological examination during all stages of diagnosis and treatment.

Abstract
PURPOSE A basal ganglia (BG) germinoma is a rare tumor, and the optimal treatment remains unknown. We evaluated the clinical outcomes of treatment of BG germinoma in pediatric patients in Taiwan. METHODS We retrospectively reviewed the medical records of 34 children with BG germinoma who were treated with radiotherapy (RT) at Taipei Veterans General Hospital between 1989 and 2016. The median follow-up time is 8.3 years (1.8-25.2 years). Survival was analyzed using the Kaplan-Meier estimate. Univariate Cox proportional-hazards models were used to identify the potential risk factors. RESULTS Only four patients (11.8%) experienced recurrence and all successfully underwent salvage therapy. One patient (2.97%) died due to suspected radiotherapy (RT)-related sarcoma in the scalp. The 2-, 3-, and 5-year DFS rates were 91.2%, 88.2%, and 79.4%, respectively; the 2-, 3-, and 5-year OS rates were 97.1%, 94.1%, and 82.4%, respectively. Focal RT showed low DFS in the Kaplan-Meier survival curves (P = .028) compared with non-focal RT (whole ventricle, whole brain, or cranial spinal area). In the univariate Cox proportional-hazards model, there was a significant difference in DFS between focal and non-focal RT (P = .03). There is no difference in DFS and OS between BG germinoma patients and non-BG germinoma patients. CONCLUSIONS We found an excellent DFS and OS in pediatric patients with BG germinoma treated with RT. Whole ventricle irradiation is recommended for good tumor control and low treatment-related toxicity. BG germinoma patients showed similar treatment results as germinoma patients in other common sites.

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.

Induction Chemotherapy Reduces Radiation Therapy Dose and Volume in the Treatment of Intracranial Germinoma: Results of the SMC-G13 Trial. Int J Radiat Oncol Biol Phys 2020; 108:649-656. [PMID: 32502506 DOI: 10.1016/j.ijrobp.2020.05.051] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2019] [Revised: 05/20/2020] [Accepted: 05/23/2020] [Indexed: 01/14/2023]
Abstract
PURPOSE We performed a prospective single-arm trial (NCT02782754) to explore the feasibility of reducing radiation therapy (RT) dose when induction chemotherapy is combined in the treatment of intracranial germinoma with beta-human chorionic gonadotropin levels <200 mIU/mL. METHODS AND MATERIALS All patients aged 3 to 35 years from November 2012 to June 2018 were eligible for this study. Four cycles of induction chemotherapy were given before RT. Carboplatin/etoposide and cyclophosphamide/etoposide regimens were used in alternation every 3 weeks. A dose of 18 Gy of craniospinal RT for metastatic tumors, whole brain RT for basal ganglia tumors, or otherwise whole ventricular RT followed by 12.6 Gy of boost RT to the primary tumor bed was administered after induction chemotherapy. The primary endpoint of this study was progression-free survival. RESULTS A total of 41 consecutive patients were enrolled (location: suprasellar in 12, pineal in 12, both suprasellar and pineal in 11, and basal ganglia in 6 patients). Eleven patients had leptomeningeal seeding. Toxicity during chemotherapy was mild, except for bone marrow suppression. Tumor status after induction chemotherapy was complete response in 33 patients and partial response in 8. All but 2 patients completed the scheduled treatment. All patients but 1 remained event free during a median follow-up of 3.4 (range, 0.3-7.0) years from diagnosis. The 1 patient experienced relapse and died of tumor bleeding. Late effects were not significant except for neuroendocrine dysfunction already present at diagnosis. Vertical growth and cognitive function were not significantly disturbed by treatment. CONCLUSIONS This study showed the feasibility of reducing RT dose/volume with induction chemotherapy in pathologically pure germinoma with elevated beta-human chorionic gonadotropin levels up to 200 mIU/mL.

Abstract
BACKGROUND Germinomas are rare intracranial lesions, with medulla germinomas being reported in only approximately 20 cases to date. These tumors are extremely sensitive to radiotherapy, and knowledge of them can allow for accurate diagnosis as well as significantly impact treatment and prognosis. CASE DESCRIPTION We present a case of medullary germinoma and review the cases previously reported in the literature. CONCLUSIONS A few imaging characteristics are noted in multiple cases, such as cystic components, enhancement, and absence of hydrocephalus. These features can provide clues to diagnosis of this rare entity.

Abstract
INTRODUCTION Extragonadal germinomas rarely emerge from the brain stem; however, proper diagnosis and treatment can result in favorable prognosis. Unfortunately, the preoperative diagnosis of medulla oblongata germinoma is difficult due to insufficient clinical signs and symptoms that are specific to this diagnosis. Case Representation: We present a 12-year-old male patient with an intra-fourth-ventricular germinoma, derived from the medulla oblongata, with no abnormalities in the supratentorial region. The germinoma was initially assessed by advance MRI sequences, including diffusion-weighted imaging, T1 perfusion, and spectroscopy. CONCLUSION In summary, although existing imaging technologies cannot completely distinguish germinomas from other primary brain neoplasms in the fourth ventricle, in patients aged between 12 and 40 years, a small mass on the dorsal side of medulla oblongata that emerges into the fourth ventricle and is characterized by homogeneous contrast enhancement, the absence of calcification and hemorrhage, and the lack of hydrocephalus should be considered for a potential medulla oblongata germinoma diagnosis.

Abstract
PURPOSE To perform a retrospective analysis of patients with intracranial germinoma treated in our department to evaluate treatment outcomes and determine optimal treatment strategies. METHODS We reviewed the treatment outcomes of 170 patients with intracranial germinoma who were treated in our department from January 1996 to January 2017. The median patient age was 15 years old. Among the patients, 56 (33%) were pathologically diagnosed, and 114 (67%) were diagnosed clinically. Various radiation fields and doses were used. Cerebrospinal fluid (CSF) and serum beta-human chorionic gonadotropin (β-HCG) levels were examined before treatment in 114 patients. Endocrinological evaluation was performed in 141 patients before and after treatment. A total of 38 patients received chemotherapy prior to radiotherapy (RT). The median follow-up time was 64.5 months (range 4-260.5 months). RESULTS The 5- and 10-year overall survival (OS) rates were 94.5% and 91.3%, respectively. The relapse-free survival (RFS) rates at 5- and 10-years were 91.9% and 78.1%, respectively. Relapses occurred in 18 patients within 6 months-10 years. The spinal cord metastasis rate was 3.4% in patients with a localized lesion who did not receive spinal cord irradiation and 16.7% in patients with bifocal disease who were treated using whole ventricular irradiation (WVI) or whole brain radiotherapy (WBRT). Treatment failure did not occur in patients receiving chemoradiotherapy or in patients receiving three-dimensional conformal radiation therapy (3D-CRT)/intensity-modulated radiation therapy (IMRT). The RFS rate did not have a statistically significant correlation with the CSF/serum β-HCG level. After RT, 19.1% of the patients developed newly impaired pituitary function and required hormone replacement therapy. CONCLUSIONS WVI or WBRT+ primary boost (PB) is a sufficient irradiation field for localized intracranial germinoma, while patients with bifocal disease should undergo craniospinal irradiation (CSI), especially when treated with RT alone. CSF β-HCG is not a prognostic marker for intracranial germinomas. The treatment results of chemotherapy followed by reduced-dose RT are comparable to those of RT alone. IMRT is recommended for intracranial germinoma to improve the target volume accuracy and decrease the complications of RT.

Abstract
Central nervous system germ cell tumors are rare intracranial tumors that mainly occur in pediatrics with substantial variation in the incidence among different regions and genders. Histologically, central nervous system germ cell tumors can be divided into germinomas and nongerminomatous germ cell tumors. The molecular pathology of central nervous system germ cell tumors, particularly germinomas, is mainly based on the presence of isochromosome 12p, gain-of-function of the KIT gene, and a globally low DNA methylation profile. Diagnoses and differential diagnoses are conducted through imaging, tumor marker detection, surgical biopsy, and cerebrospinal fluid cytology. Germinomas are often treated via whole-ventricular radiotherapy or neoadjuvant chemotherapy combined with reduced-dose whole-ventricular radiotherapy, whereas nongerminomatous germ cell tumors are mainly treated with chemotherapy, surgical resection, and radiotherapy (individually or in combination), depending on tumor composition. Because the main population of patients is pediatric, extending overall survival and reducing treatment side effects should be the main goals of future studies.

Abstract
PURPOSE Complications can occur following a prolonged latency period after radiation therapy for cancer, and this is a growing concern because secondary tumors are potentially fatal. Few studies have examined secondary tumors in patients who received radiation therapy as children. METHODS AND MATERIALS This retrospective study examined 1697 pediatric patients with central nervous system tumors who received treatment at Taipei Veterans General Hospital from January 1, 1975, to December 31, 2013. Secondary tumors developed in 27 of 681 patients who received cranial irradiation. Overall survival was estimated using the Kaplan-Meier method, and the significance of differences was determined by the log-rank test. RESULTS The overall cumulative incidence of secondary tumors at 25 years was 3.96%, and there were similar numbers of male patients (n = 16) and female patients (n = 11). The mean age at diagnosis was 8.8 years (range, 3-16.5 years), the median dose of cranial irradiation was 52.5 Gy (mean, 53.4 Gy), the mean latency period was 14.6 years (range, 2-33 years), and the mean age at diagnosis of a secondary tumor was 23.1 years. The secondary tumors were mainly meningiomas (n = 13), sarcomas (n = 7), and high-grade gliomas (n = 6), and the mean latency periods were 19.66, 8.00, and 10.83 years, respectively. The overall survival rate from these secondary tumors was significantly different (P < .05). Age at irradiation of <7 years and craniospinal irradiation significantly increased the risk of a secondary tumor (P < .05). Secondary tumors developed in 11 of 128 patients (8.6%) with primary medulloblastomas, which was higher than the overall cumulative incidence. CONCLUSIONS Clinicians should consider the increased risk of secondary tumors in long-term cancer survivors who received craniospinal irradiation as children. Using a selective dose de-escalation strategy or deferring radiation therapy for young patients at highest risk of secondary cancers should be studied.

MRI features of pediatric intracranial germ cell tumor subtypes. J Neurooncol 2017; 134:221-230.

Abstract
Intracranial germ cell tumors differ in histology and location, and require different clinical management strategies. We characterized the imaging features that may aid pre-operative differentiation of intracranial germinomas and non-germinomatous germ cell tumors (NGGCTs). This retrospective study analyzed 85 patients with intracranial germ cell tumors and adequate preoperative or pretreatment MRIs between 2000 and 2013 at our institution. Pretreatment MRI characteristics, apparent diffusion coefficient (ADC) values, tumor histopathology, and patient outcomes were compared. NGGCTs occurred in the pineal region and cerebral hemispheres more often than germinomas; all bifocal lesions were germinomas. NGGCTs (36.6 ± 17.0 mm) were significantly larger than germinomas (25.7 ± 11.6 mm; P = 0.002). The presence of pure solid tumor (45.5 vs. 20.0%, P = 0.033) and an infiltrative margin (20.0 vs. 3.3%, P = 0.035) were significantly more common in germinomas than NGGCTs. The presence of intratumoral T1 hyperintense foci (66.7 vs. 10.9%, P < 0.001) and moderate/marked enhancement (86.7 vs. 50.9%, P < 0.001) were significantly more common in NGGCTs than in germinomas. Mean ADCmean values (×10-3 mm2/s) were significantly lower in germinomas (1.113 ± 0.415) than in NGGCTs (2.011 ± 0.694, P = 0.001). Combined a lack of T1 hyperintense foci and an ADCmean threshold value (1.143 × 10-3 mm2/s) had the highest specificity (91.3%) and positive predictive value (92.3%), while the combination of lack of a T1 hyperintensense foci, no/mild enhancement, and an ADCmean threshold value had 100% sensitivity and 100% negative-predictive value for discriminating germinomas from NGGCTs. Pre-operative conventional MRI characteristics and diffusion-weighted MRI help clinicians to assess patients with intracranial germ cell tumors. Tumor size, location, T1 hyperintense foci, intratumoral cystic components, tumor margin and enhancing patterns demonstrate contrast between germinomas and NGGCTs. Serum tumor markers and adjunctive combination with T1 hyperintensity and/or enhancing pattern with ADC offer potential in preoperative differentiating intracranial germinomas and NGGCTs.

Abstract
Background Beta (β)-human chorionic gonadotropin (β-HCG) is used to confirm the diagnosis and plan treatment of intracranial germinomas. However, the cutoff values of serum β-HCG in diagnosis of intracranial germinomas reported in the literature are inconsistent. To establish an appropriate cutoff value of serum β-HCG for diagnosis of intracranial germinomas, we retrospectively reviewed the records of intracranial tumor patients who received serum β-HCG and α-fetoprotein (AFP) tests for diagnostic purposes at our hospital from 2005 to 2014. Methods A total of 93 intracranial germinomas and 289 intracranial non-germ cell tumors were included in this study. Receiver operating characteristic (ROC) analysis was used to evaluate the sensitivity and specificity of 3 cutoffs (0.1, 0.4, and 0.5 mIU/mL) for diagnosing intracranial germinomas. The serum β-HCG level of intracranial germinoma patients was further analyzed to investigate the effect of metastasis status and tumor location on serum β-HCG level. Results The area under the ROC curve was 0.81 (P < .001), suggesting β-HCG is an effective marker. Of the 3 cutoff values, 0.1 mIU/mL possessed a highest sensitivity (66.67%) and good specificity (91%). Although there was no β-HCG level difference between metastatic and non-metastatic intracranial germinoma patients, the diagnostic rate of metastatic neurohypophyseal germinomas was significantly higher than that of its non-metastatic counterpart (P < .05), implying that the location of the germinoma might need to be considered when β-HCG is used as a marker to predict metastasis. Conclusions Determining an optimal cutoff of serum β-HCG is helpful for assisting the diagnosis of intracranial germinoma.

Abstract
OBJECTIVE To evaluate the feasibility of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) for predicting tumor response to radiotherapy in patients with suspected primary central nervous system (CNS) germ cell tumors (GCTs). METHODS DCE-MRI parameters of 35 patients with suspected primary CNS GCTs were obtained prior to diagnostic radiation, using the Tofts and Kermode model. Radiosensitivity was determined in tumors diagnosed 2 weeks after radiation by observing changes in tumor size and markers as a response to MRI. Taking radiosensitivity as the gold standard, the cut-off value of DCE-MRI parameters was measured by receiver operating characteristic (ROC) curve. Diagnostic accuracy of DCE-MRI parameters for predicting radiosensitivity was evaluated by ROC curve. RESULTS A significant elevation in transfer constant (K(trans)) and extravascular extracellular space (Ve) (P=0.000), as well as a significant reduction in rate constant (Kep) (P=0.000) was observed in tumors. K(trans), relative K(trans), and relative Kep of the responsive group were significantly higher than non-responsive groups. No significant difference was found in Kep, Ve, and relative Ve between the two groups. Relative K(trans) showed the best diagnostic value in predicting radiosensitivity with a sensitivity of 100%, specificity of 91.7%, positive predictive value (PPV) of 95.8%, and negative predictive value (NPV) of 100%. CONCLUSIONS Relative K(trans) appeared promising in predicting tumor response to radiation therapy (RT). It is implied that DCE-MRI pre-treatment is a requisite step in diagnostic procedures and a novel and reliable approach to guide clinical choice of RT.

Abstract
Intracranial germ cell tumors (ICGCT) occur in 2-11% of children with brain tumors between 0-19 years of age. For treatment of germinoma, relatively low radiation doses with or without chemotherapy show excellent 10 year survival rate of 80-100%. Past studies showed that neoadjuvant chemotherapy combined with focal radiotherapy resulted in unacceptably high rates of periventricular tumor recurrence. The use of generous radiation volume which covers the whole ventricular space with later boost treatment to primary site is considered as standard treatment of intracranial germinomas. For non-germinomatous germ cell tumors (NGGCT), 10-year overall survival rate is still much inferior than that of intracranial germinoma despite intensive chemotherapy and high-dose radiotherapy. Craniospinal radiotherapy combined with cisplatin-based chemotherapy provides the best treatment outcome for NGGCT; 60-70% of overall survival rate. There is a debate on the surgical role whether surgery can contribute to improved treatment outcome of NGGCT when added to combined chemoradiotherapy. Because higher dose of radiotherapy is required for treatment of NGGCT than for germinoma, it is tested whether whole ventricular irradiation can replace craniospinal irradiation in intermediate risk group of NGGCT to minimize radiation-related late toxicity in the recent studies. To minimize the treatment-related neural deficit and late sequelae while maintaining long-term survival rate of ICGCT patients, optimized administration of chemotherapy and radiotherapy should be selected. Use of technically upgraded radiotherapy modalities such as intensity-modulated radiotherapy or proton beam therapy is expected to bring an improved neurocognitive outcome with longitudinal assessment of the patients.

Treatment results and prognostic factors for intracranial nongerminomatous germ cell tumors: single institute experience. Childs Nerv Syst 2015; 31:683-91.

Abstract
PURPOSE This study aimed to evaluate the treatment of intracranial nongerminomatous germ cell tumors (NGGCT) and to identify the prognostic factors for survival. METHODS Thirty-nine patients with nondisseminated NGGCTs, excluding those with pure mature teratomas, were treated between January 1985 and December 2010. Twenty-four patients received gross total or partial removal, 11 had excision biopsies, and 4 had no surgery. Radiotherapy was given postoperatively or definitively with a median tumor bed dose of 54 Gy (range 30-54) with or without craniospinal irradiation. All patients received ten cycles of adjuvant chemotherapy, vinblastine, bleomycin, etoposide, and cisplatin after radiotherapy, except for one with mixed anaplastic astrocytoma component who received oral temozolomide. Survival and prognostic factors were estimated by the Kaplan-Meier method and log-rank tests, respectively. RESULTS After a median follow-up of 77.7 months (range 14-336), the 6-year overall survival (OS) and progression-free survival (PFS) were 74.4 and 79.5 %, respectively. Inferior PFS was associated with lesions in the suprasellar region (p = 0.017), poor pathological features (p = 0.048), and with poor image (p < 0.0001) and tumor marker (TM) response (p = 0.003) to irradiation. Decreased OS was associated with lesions in the suprasellar region (p = 0.026) and with poor image (p < 0.0001) and TM response (p = 0.027) to irradiation. Neither the extent of surgery nor the radiation field was found to significantly influence survival. CONCLUSIONS By our multimodality approach, patients achieved comparable outcomes. Other than poor pathological features, patients with poor responses to radiotherapy are prone to early recurrence and inferior survival. These patients should be focused for more intensive adjuvant treatment.

Abstract
The aim of this study was to evaluate the predictors of long-term survival following postoperative therapy for suprasellar germ cell tumors (GCTs). A total of 23 patients with pathologically confirmed suprasellar GCTs were reviewed between April, 1987 and October, 2008. The predictors were identified with a univariate Cox proportional hazards model and the results were used to group patients according to outcome. The overall survival (OS) and progression-free survival (PFS) rates for the good- and poor-prognosis two groups were estimated with Kaplan-Meier analysis, with log-rank tests used to assess differences between the groups. The OS rate for all patients was 82.6% at 5 and 72.9% at 10 years. Lesion size (2-4 vs. >4 cm) and pathological type (pure germinoma vs. mixed GCT) were the only significant predictors of OS (P<0.05). The OS rate for the good-prognosis group was 92.9% at both 5 and 10 years, whereas the corresponding rates for the poor-prognosis group were 66.7 and 40.0%, respectively (P=0.020). The PFS rate for the good-prognosis group was 92.9% at 5 and 85.7% at 10 years, whereas the corresponding PFS rates for the poor-prognosis group were 44.4 and 33.3%, respectively (P=0.007). Lesion size and histology predicted outcome following postoperative therapy for suprasellar GCT. Therefore, pathological diagnosis is recommended whenever possible, as histology may dictate the choice of treatment.

Abstract
BACKGROUND AND PURPOSE Suprasellar papillary craniopharyngiomas and germ cell tumors in adults share some clinical and imaging similarities but have different therapeutic strategies and outcomes. This study aimed to evaluate the pretreatment diagnosis of these 2 tumors to improve the therapeutic outcome. MATERIALS AND METHODS We retrospectively enrolled 18 adults with papillary craniopharyngiomas and 17 with germ cell tumors. The MR imaging findings were evaluated, including signal change and anatomic extension. The medical records were reviewed to collect clinical findings, management, and outcomes. RESULTS The clinical findings of papillary craniopharyngiomas versus germ cell tumors were as follows: age: 46 ± 13.9 years versus 23 ± 7.1 years (P < .0001); diabetes insipidus: 2/18 (11%) versus 11/17 (65%) (P = .001); recurrence 13/16 (81%) versus 4/17 (24%) (P = .0031). The MR imaging findings of papillary craniopharyngiomas versus germ cell tumors were as follows—pituitary stalk thickening: 1.6 ± 0.4 mm versus 5.4 ± 4.2 mm (P < .0001); vertical infundibular extension: 1/18 (6%) versus 16/17 (94%) (P < .0001); sagittal spheric shape: 17/18 (94%) versus 1/17 (6%) (P < .0001); diffusion restriction: 1/17 (6%) versus 8/12 (67%) (P = .0009). CONCLUSIONS Younger age, diabetes insipidus, MR imaging characteristics of restricted diffusion, and vertical infundibular extension favor the diagnosis of germ cell tumors. Spheric shape without infundibular infiltration provides clues to papillary craniopharyngiomas, which originate from the pars tuberalis and are located outside the third ventricle. We suggest that suprasellar germ cell tumor is possibly an intraventricular lesion. Appropriate treatment planning can be initiated according to the diagnosis and anatomic location.

Abstract
Primary intracranial germ cell tumours (ICGCT) are a rare group of brain tumours arising predominantly in the paediatric and pre-adult population, accounting for up to 9.5% of paediatric brain tumours in East Asia. The National Cancer Centre Singapore (NCCS) is a tertiary referral centre for patients from all over South-East Asia. Our study aims to describe the characteristics of ICGCT patients in South-East Asia. Data on all patients with ICGCT who were seen at the Therapeutic Radiology Department of NCCS from 2000 to 2013 were collected retrospectively. Patient demographics, disease characteristics and treatment outcomes were analysed. Characteristics and survival of our patients were similar to other centres. Pure germinomas demonstrated 5 year overall survival (OS) and disease-free survival (DFS) rates of 89.2% (95% confidence interval [CI] 60.2-97.5) and 85.2% (95%CI 60.8-95.0) respectively. Secreting germinomas, non-germinomatous germ cell tumours and mixed germ cell tumours were evaluated together and demonstrated 5 year OS of 70.6% (95%CI 41.0-87.3) and DFS of 61.4% (95%CI 31.9-81.3). Patients ⩽ 12 years had marginally better 5 year OS than their older counterparts (81.0% [95%CI 49.5-93.9] versus 77.9% [95%CI 47.3-92.0], respectively). Patients who underwent extended field radiotherapy had longer OS and DFS than those who received local field irradiation. Treatment outcomes of our ICGCT patients are comparable with those in other Asian and Western centres. Extended field radiotherapy is a pivotal component of ICGCT treatment. Adding chemotherapy confers no extra survival benefit in treating germinomas. Treatment of mixed germ cell tumours and non-germinomatous germ cell tumours involves a multidisciplinary approach that varies for each histological subtype.

Long-term follow-up and quality of life in patients with intracranial germinoma. Neurosurg Rev 2014; 37:445-50; discussion 451.

Abstract
Intracranial germinomas are fairly rare tumors occurring mostly in children or young adults with a comparatively good prognosis. Radiation is the preferred treatment of choice for this diagnosis. It has been thoroughly studied to what extent radiation doses and fields can be limited in order to avoid side effects in these young patients. The role of chemotherapy remains unclear, whereas surgery is limited to biopsy for proof of histology. Regarding the good overall survival rate, quality of life is a significant aspect to consider in these patients. We present a single institution analysis of patients with intracranial germinoma and analyze the long-term outcome with special regard to quality of life. Thirty-three patients with intracranial germinomas were analyzed by chart review, telephone interview, and neurological assessment. Additionally, a survey on quality of life was performed. The 10-year overall survival rate was 82.1 % at a mean follow-up of 141 (22-306) months. Three quarters (76 %) of the patients reached a favorable neurological outcome on the Modified Rankin Scale (mRS 0-2). However, the self-reported quality of life was significantly worse in germinoma patients compared with a healthy control group (p < 0.001). Surgical resection of the tumor led to no improvement regarding overall survival, neurological outcome, and quality of life. In terms of cognitive functioning, patients with tumor resection were significantly more impaired than biopsied patients (p = 0.04). Although germinomas are efficiently treatable tumors, the restrictions in quality of life in these often young patients are considerable, including financial difficulties. There seems no justification for tumor resection in newly diagnosed cases suspicious for germinoma as the cognitive outcome is worse than in biopsied patients, and there is no effect on overall survival.

Abstract
An intracranial germinoma is a tumor that is sensitive to radiotherapy. As medulla oblongata germinomas are extremely rare, determining an accurate preoperative diagnosis is challenging. Two cases of medulla oblongata lesions were surgically treated, and a postoperative diagnosis of germinoma was determined in both of the cases. The tumor in one patient completely resolved after a treatment course consisting of surgical intervention, radiotherapy and chemotherapy; the other patient, who did not receive any type of adjuvant treatment after surgery, suffered from tumor relapse and died from pneumonia 8 months following surgery. A preoperative diagnosis of medulla oblongata germinoma is difficult because of the lack of specific clinical signs and symptoms. If the correct diagnosis is reached, patients can have a favorable prognosis with proper evaluation and treatment. An invasive operation can potentially lesion and impair the function of the medulla oblongata, which is fatal to the patient.

Abstract
BACKGROUND The notable survival chances of intracranial germ cell tumors (icGCTs) lead to a rising concern over long-term neurocognitive outcome. Yet, prior evidence related to this issue fails to provide a comprehensive examination of the effects of tumor location and radiotherapy. We attempt to explore their impacts on the neuropsychological functions and life quality in children with icGCT after multimodality treatments. METHODS A retrospective review of 56 patients diagnosed with icGCTs at age <20 and treated at the Taipei Veterans General Hospital was provided. Intelligence, memory, visual organization, attention, and executive function were assessed by neurocognitive tests; adaptation to life, emotional and behavioral changes, interpersonal relationships, and impact on the family were evaluated by parent-report instruments. Effects of tumor locations (germinomas and nongerminomatous malignant germ cell tumors in the pineal, suprasellar, and basal ganglia) and irradiation on these measurements were examined. RESULTS Patients with tumors in the basal ganglia region had lower full-scale IQs than those with tumors in the pineal or suprasellar regions. Subscores of intelligence scale and short-term retention of verbal and visual stimuli showed evident group differences, as did the quality of life and adaptive skills, particularly in psychosocial domains. Patients treated with whole-ventricular irradiation had better outcomes. Extensive irradiation field and high irradiation dosage influenced intellectual functions, concept crystallization, executive function, and memory. CONCLUSIONS Tumor location and irradiation field/dosage appear to be the crucial factors related to certain neuropsychological, emotional, and behavioral dysfunctions that in turn alter the quality of life in children with icGCTs who survive after treatment.

Abstract
BACKGROUND Intracranial germinomas (IG) are rare and highly curable tumors. The incidence and optimal treatment of recurrences are not well defined. CASE REPORT A 34-year-old male was diagnosed with a late recurrence of an IG 14 years after the initial diagnosis and treatment. The diagnosis was complicated by the absence of tumor markers and delayed histological sampling of the lesion. Upon histological confirmation, the patient received 2 cycles of conventional chemotherapy, followed by 2 cycles of highdose chemotherapy and peripheral blood stem cell transplantation. The patient achieved a complete remission on magnetic resonance imaging scan. Consolidating radiation of the involved field was performed after termination of the chemotherapy. CONCLUSION Limited information on the optimal management of late relapses of IG call for individualized therapeutic approaches. Platinum-based chemotherapy, followed by high-dose chemotherapy and consolidative radiation, appears to be feasible and effective in this situation.

Abstract
PURPOSE Central nervous system germinomas often extend or disseminate into the ventricular and subarachnoid space. We present a case of primary central nervous system germinoma consisting mainly of meningeal dissemination, which is extremely unusual. CASE REPORT A 16-year-old boy presented with pure germinoma, manifesting as anorexia and headache for 10 days. Radiological examinations revealed a large mass lesion in the posterior fossa and a small mass lesion on the pineal lobule with thickening of the tentorium cerebelli and falx. The patient underwent partial removal of the infratentorial tumor via open surgery. Intraoperative findings indicated extension of the dural and supracerebellar mass lesions into the epiarachnoid space. Three chemotherapy courses comprising ifosfamide, etoposide, and cisplatin were administered after the surgery. Craniospinal irradiation was administered subsequently. The adjuvant therapy had a complete response. CONCLUSION Central nervous system germinoma cells may have similar compatibility to meningeal components as they do to cerebrospinal fluid or the ventricular system. If there is a possibility of the tumor extending into the subdural space during surgical intervention or other events, a range of postdiagnostic irradiation should be considered to cover a wider range.

Abstract
External beam radiotherapy has proven effective in managing intracranial germinoma. However, concerns regarding long-term neurocognitive and endocrine sequelae led to the addition of chemotherapy, to reduce radiation target volumes. There is a paucity of data on patterns of failure in patients treated with differing radiation field sizes. We review our experience at a tertiary children's hospital treating children with intracranial germinoma, using induction chemotherapy followed by radiation therapy to various treatment volumes (craniospinal irradiation, whole ventricular irradiation, whole brain radiation therapy, and focal radiotherapy). Ten patients with primary intracranial germinoma, treated from November 1995-March 2011, were included. The primary treatment involved platinum-based chemotherapy, followed by definitive radiotherapy. The median follow-up period was 4.3 years (range, 0.75-13.25 years). The 5-year overall survival for the entire group was estimated at 85.7%, and the 5-year disease-free survival was estimated at 75.0%. Two treatment failures occurred at 5 and 28 months, both in patients with single lesions in the pineal region treated with focal radiotherapy only. Based on the patterns of failure, our outcomes support the continued use of the whole ventricular field vs a focal field, even in patients with limited disease who demonstrate a complete response to neoadjuvant chemotherapy.

Abstract
PURPOSE Initially disseminated intracranial germinomas (IDIGs) can be observed in pre-adult and adolescent brain tumor patients. However, the disease prognosis is undetermined, and the method of optimal treatment remains controversial. METHODS From January 1990 to January 2011, data on 91 intracranial germinoma patients (≤20 years old) were gathered from the Pediatric Brain Tumor database at Taipei Veterans General Hospital. A total of seven patients with a median age of 17.0 years had IDIGs (lesion sites >2), including IDIGs in the ventricular system or the spinal column. Craniospinal irradiation (CSI) plus a primary or metastatic boost was the mainstay strategy for radiotherapy. Six out of a total of seven patients (85.7%) also received systemic chemotherapy (CHT) after radiotherapy. Survivals rates between IDIGs and patients without dissemination were estimated using the Kaplan-Meier method. RESULTS The median follow-up time for all seven patients was 67.5 months (range, 10.3-142.3 months). None of the IDIG patients experienced a recurrence or mortality after the completion of treatment. The 5- and 10-year disease-free survival (DFS) between IDIG and non-dissemination patients were 100%, 100%, 93.0% and 78.6%, respectively (p = 0.339). The 5- and 10-year overall survival (OS) between IDIGs and non-dissemination cases were 100%, 100%, 93.7% and 89.4%, respectively (p = 0.473). CONCLUSIONS IDIG patients did not show reduced survival compared to non-dissemination patients if optimal radiotherapy and chemotherapy were used together.
