Abstract
BACKGROUND Medulloblastoma is a highly malignant, embryonal tumor, which is rare in adults, and shows distinct clinical, histopathological, molecular and treatment response features. METHODS We retrospectively investigated 44 adults (age 17-48 years) with a histological diagnosis of medulloblastoma, and in 23 immunohistochemistry was used to identify the molecular subgroups. We analyzed demographic, diagnostic, therapeutic and cognitive data, and correlated with PFS (progression-free-survival) and OS (overall survival). RESULTS We observed a male prevalence and a median age of 31 years. Symptoms at onset were related to infratentorial location, while myeloradicular and/or cranial nerve involvement was rare. Histological examination showed the classic variant in 75% of patients, the desmoplastic/nodular in 23% and the anaplastic in one. As for molecular diagnosis, 17 patients were SHH and 6 non-WNT/non-SHH (5 group 4 and 1 group 3), while no WNT subgroup was found. The SHH subgroup had a prevalence of high-risk patients and leptomeningeal involvement. Patients underwent gross total or subtotal/partial resection, and craniospinal irradiation, followed in 20 cases by adjuvant chemotherapy. Median OS and PFS were 16.9 and 12 years, respectively. Metastatic disease at presentation and subtotal/partial resection were associated with worse prognosis, while the addition of chemotherapy did not yield a significant advantage over radiotherapy alone. Cognitive impairment in long-term survivors was limited and late relapses occurred in 15% of patients. CONCLUSIONS Future studies with adequate sample size and long-term follow-up should prospectively investigate the role of surgery and adjuvant therapies across the different molecular subgroups to see whether a personalized approach is feasible.

Abstract
Brain tumors account for the majority of cancer-related deaths in adolescents and young adults (AYAs), defined as individuals aged 15 to 39. AYAs constitute a distinct population in which both pediatric- and adult-type central nervous system (CNS) tumors can be observed. Clinical manifestations vary depending on tumor location and often include headaches, seizures, focal neurological deficits, and signs of increased intracranial pressure. With the publication of the updated World Health Organization CNS tumor classification in 2021, diagnoses have been redefined to emphasize key molecular alterations. Gliomas represent the majority of malignant brain tumors in this age group. Glioneuronal and neuronal tumors are associated with longstanding refractory epilepsy. The classification of ependymomas and medulloblastomas has been refined, enabling better identification of low-risk tumors that could benefit from treatment de-escalation strategies. Owing to their midline location, germ cell tumors often present with oculomotor and visual alterations as well as endocrinopathies. The management of CNS tumors in AYA is often extrapolated from pediatric and adult guidelines, and generally consists of a combination of surgical resection, radiation therapy, and systemic therapy. Ongoing research is investigating multiple agents targeting molecular alterations, including isocitrate dehydrogenase inhibitors, SHH pathway inhibitors, and BRAF inhibitors. AYA patients with CNS tumors should be managed by multidisciplinary teams and counselled regarding fertility preservation, psychosocial comorbidities, and risks of long-term comorbidities. There is a need for further efforts to design clinical trials targeting CNS tumors in the AYA population.

Management and Long-term Outcomes of Adults With Medulloblastoma: A Single-Center Experience. Neurology 2023; 101:e1256-e1271. [PMID: 37524533 PMCID: PMC10516280 DOI: 10.1212/wnl.0000000000207631] [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: 10/26/2022] [Accepted: 05/30/2023] [Indexed: 08/02/2023] Open
Abstract
BACKGROUND AND OBJECTIVES Medulloblastomas are embryonal tumors predominantly affecting children. Recognition of molecularly defined subgroups has advanced management. Factors influencing the management and prognosis of adult patients with medulloblastoma remains poorly understood. METHODS We examined the management, prognostic factors, and, when possible, molecular subgroup differences (subset) in adult patients (aged 18 years or older) with medulloblastoma from our center (specialty Neuro-Oncology clinic within a large academic practice) diagnosed between 1992 and 2020. Molecular subtyping corresponding to the 2021 WHO Classification was performed. Kaplan-Meier estimates (with log-rank test) were performed for univariate survival analysis with Cox regression used for multivariate analyses. RESULTS We included 76 adult patients with medulloblastoma (62% male), with a median age of 32 years at diagnosis (range: 18-66) and median follow-up of 7.7 years (range: 0.6-27). A subset of 58 patients had molecular subgroup characterization-37 SHH-activated, 12 non-WNT/non-SHH, and 9 WNT-activated. Approximately 67% underwent gross total resection, 75% received chemotherapy at diagnosis, and 97% received craniospinal irradiation with boost. The median overall survival (OS) for the whole cohort was 14.8 years. The 2-, 5-, and 10-year OS rates were 93% (95% CI 88-99), 86% (78-94), and 64% (53-78), respectively. Survival was longer for younger patients (aged 30 years or older: 9.9 years; younger than 30 years: estimated >15.4 years; log-rank p < 0.001). There was no survival difference by molecular subgroup or extent of resection. Only age at diagnosis remained significant in multivariate survival analyses. DISCUSSION We report one of the largest retrospective cohorts in adult patients with medulloblastoma with molecular subtyping. Survival and molecular subgroup frequencies were similar to prior reports. Survival was better for adult patients younger than 30 years at diagnosis and was not significantly different by molecular subgroup or management characteristics (extent of resection, RT characteristics, or chemotherapy timing or regimen).

Abstract
Medulloblastoma (MB) is a malignant embryonal tumor of the posterior fossa belonging to the family of primitive neuro-ectodermic tumors (PNET). MB generally occurs in pediatric age, but in 14–30% of cases, it affects the adults, mostly below the age of 40, with an incidence of 0.6 per million per year, representing about 0.4–1% of tumors of the nervous system in adults. Unlike pediatric MB, robust prospective trials are scarce for the post-puberal population, due to the low incidence of MB in adolescent and young adults. Thus, current MB treatments for older patients are largely extrapolated from the pediatric experience, but the transferability and applicability of these paradigms to adults remain an open question. Adult MB is distinct from MB in children from a molecular and clinical perspective. Here, we review the management of adult MB, reporting the recent published literature focusing on the effectiveness of upfront chemotherapy, the development of targeted therapies, and the potential role of a reduced dose of radiotherapy in treating this disease.

Abstract
BACKGROUND The role of chemotherapy (CT) in the treatment of adult patients with medulloblastoma (MB) is unclear. The aim of this study is to compare the survival difference between adult patients with MB treated with and without chemotherapy. METHODS Data were derived from the SEER (Surveillance Epidemiology and End Results) database from 2010 to 2018. The Kaplan-Meier method with log-rank tests, univariate and multivariate Cox proportional hazard analyses, and propensity score matching (PSM) were used to investigate the association between chemotherapy and survival. We further conducted an exploratory subgroup analysis. The outcomes of interest were cancer-specific survival (CSS) and overall survival (OS). RESULTS We included 333 patients in this study, with 227 patients in the CT cohort and 106 in the nonchemotherapy cohort. The median follow-up time and the median age of the study population were 61 months and 30 years, respectively. The 5-year CSS of the CT cohort was superior to the nonchemotherapy cohort, whereas the 5-year OS was not. Kaplan-Meier curves after PSM supported the survival benefit of CT on CSS but not on OS. In the multivariate analysis after PSM, CT was the only prognostic factor for CSS, whereas there were no independent prognostic factors for OS. The survival of patients receiving CT who were diagnosed between 2010 and 2018 was better than that of previous patients. The subgroup analysis showed that there were interaction effects between CT and sex. CONCLUSIONS CT improved CSS for adult patients with MB. With therapeutic advances, adult patients with MB might benefit from the use of CT.

Abstract
Simple Summary Medulloblastoma is a rare brain tumor that affects children and adults. Treatment with surgery, radiation, and chemotherapy currently cures most patients; however, ~30% of all patients have poor clinical outcomes despite treatment. Prospective clinical trials have historically excluded older patients, while recent advances in molecular diagnostics have enhanced our understanding of tumorigenesis. The aim of this literature review is to discuss the history of clinical trials in medulloblastoma and to argue in favor of prioritizing molecular drivers of disease as trial inclusion features rather than an arbitrary age cutoff. Abstract Medulloblastoma is a rare malignant brain tumor that predominantly affects children but also occurs in adults. The incidence declines significantly after age 15, and distinct tumor molecular features are seen across the age spectrum. Standard of care treatment consists of maximal safe surgical resection followed by adjuvant radiation and/or chemotherapy. Adjuvant treatment decisions are based on individual patient risk factors and have been informed by decades of prospective clinical trials. These trials have historically relied on arbitrary age cutoffs for inclusion (age 16, 18, or 21, for example), while trials that include adult patients or stratify patients by molecular features of disease have been rare. The aim of this literature review is to review the history of clinical trials in medulloblastoma, with an emphasis on selection criteria, and argue in favor of rational and inclusive trials based on molecular features of disease as opposed to chronological age. We performed a scoping literature review for medulloblastoma and clinical trials and include a summary of those results. We also discuss some of the significant advances made in understanding the molecular biology of medulloblastoma within the past decade, most notably the identification of four distinct subgroups based on gene expression profiling. We will also cite the recent experiences of childhood leukemia and the emergence of tissue-agnostic therapies as examples of successes of rationally designed, inclusive trials translating to improved clinical outcomes for patients across the age spectrum. Despite the prior trial history and recent molecular advances outcomes remain poor for ~30% of medulloblastoma patients. We believe that defining patients by the specific molecular alterations their tumors harbor is the best way to ensure they can access potentially efficacious therapies on clinical trials.

Abstract
PURPOSE Medulloblastoma is a rare tumor in adults and the use of adjuvant chemotherapy in average risk patients is debated. METHODS Patients included in our study were ⩾16 years of age, had histologically confirmed medulloblastoma, and underwent adjuvant radiotherapy with or without chemotherapy. Average risk was defined according to the Chang classification. RESULTS We included 48 average-risk patients. Median follow-up was 151.5 months (95% confidence interval, 124.5-178.5). Both progression-free survival (PFS) and overall survival (OS) were significantly influenced by adjuvant chemotherapy (PFS: hazard ratio [HR], 0.334, p = 0.05; OS: HR, 0.187, p = 0.017) and by receiving the treatment in a referral center (PFS: HR, 0.250, p = 0.008; OS: HR, 0.295, p = 0.038). CONCLUSIONS Treating patients with average-risk medulloblastoma in a referral center improves both PFS and OS, does adding adjuvant chemotherapy.

Abstract
BACKGROUND Medulloblastoma (MB) is a malignant tumor of the central nervous system (CNS), and sarcoidosis is a chronic inflammatory disease of many organ systems, commonly affecting the lungs. No association between MB and sarcoidosis was described in the literature. MB and sarcoidosis have mutual molecular and signaling pathways that may predispose patients with sarcoidosis to develop MB. We describe a patient with sarcoidosis who developed MB. CASE DESCRIPTION The patient is a 36-year-old diagnosed with pulmonary sarcoidosis presented with ataxia, bilateral horizontal nystagmus, diplopia, and bilateral upper limb dysmetria was found to have a cerebellar mass on magnetic resonance imaging (MRI). He was initially treated with corticosteroids as a case of neurosarcoidosis. The patient's symptoms worsened, and repeat MRI showed an increase in the tumor size with hydrocephalus. External ventricular drain insertion plus midline suboccipital craniotomy and resection of the tumor was performed. Pathology revealed MB classic type, sonic hedgehog-activated. There was no cerebrospinal fluid dissemination. He received craniospinal radiation and chemotherapy. Follow-up 20 months after radiation revealed residual neurologic symptoms and no recurrence on MRI brain. CONCLUSIONS The exceedingly rare coexistence of adult MB and sarcoidosis may have a causal relationship based on specific common molecules. Leukotrienes, stimulation of astrocytes and Purkinje neurons, and the sonic hedgehog signaling pathway can be considered. Further genetic and molecular studies are merited.

Abstract
Medulloblastoma is an embryonal neuroepithelial tumor that affects mainly childhood and more rarely adults. Medulloblastoma occurring as multiple nodules at diagnosis is a rare and tricky presentation. Here, we describe the case of a previously healthy 47-year-old woman with multiple posterior fossa cerebellar tumors. Histological, immunohistochemical, and molecular analyses were performed to best characterize the two excised lesions. The histopathological analysis revealed different variants of medulloblastoma in the excised nodules, one being extensive nodularity, rare in adults, and the other desmoplastic/nodular with areas of anaplasia. Immunostains and molecular analysis classified both nodules as SHH medulloblastoma. Adult medulloblastoma is extremely rare. Important differences exist between adult medulloblastoma and medulloblastoma arising in children and infants. Such differences are in location, distribution of histological variants and of molecular subgroups, survival rates, and therapeutic options. An extensive morphological and molecular characterization of such rare tumors is necessary to choice the best-tailored therapy.

Abstract
The occurrence of medulloblastoma (MB) in the elderly is an absolutely rare event. Concerning this issue we report on two MB patients beyond the 70th year of life. Two patients older than 70 years presented with a mass in the posterior fossa without evidence of a preexisting malignant tumor. After careful radiological work-up the suspected diagnosis was metastasis of an unknown primary tumor. Both patients underwent surgery and histopathological analysis revealed MB in both cases (classical MB and desmoplastic type). The two cases presented here represent also one classical MB and one additional desmoplastic MB. To our knowledge we report for the first time that there are different molecular subtypes of MB in the elderly patients that seem to be consistent with those subtypes mainly occurring in young adults. Unfortunately the patients died within one week after surgery due to respiratory insufficiency and an unclear cause. The presented cases show that MB can occur in the elderly. Although this constellation is absolutely rare, MB should be considered in the differential diagnosis, especially when a primary tumor is not known or detected.

Abstract
BACKGROUND Medulloblastoma is a malignant tumor of the posterior fossa and is predominantly seen in children younger than 15 years of age. This tumor is uncommon in adults, especially those older than 40 years of age, and reports of cases in patients older than 60 years of age are particularly rare. Although surgery and radiotherapy play important roles in treatment of medulloblastoma in adults, addition of chemotherapy is controversial, especially prior to radiotherapy. CASE DESCRIPTION We present a case of a 63-year-old woman with an atypical medulloblastoma in the cerebellum and a lesion in the suprasellar area that did not appear to be a metastasis of the medulloblastoma. The patient underwent a subtotal resection of the cerebellar medulloblastoma, which was classified histologically as classic subtype and molecularly as non-Wingless/non-Sonic hedgehog subtype in World Health Organization 2016 classification. Then she underwent postoperative chemotherapy followed by radiotherapy. We administered chemotherapy to facilitate therapeutic diagnosis of the suprasellar lesion. The combination treatment resulted in the disappearance of the cerebellar medulloblastoma with treatment toxicity well tolerated. Additionally, the suprasellar lesion remains under control. CONCLUSIONS Even in adults over 60 years of age, medulloblastoma should be included in the differential diagnosis of a cerebellar mass. Chemotherapy for adult medulloblastoma has the potential to be efficacious and tolerable.

[PMID: 29750173 PMCID: PMC5884299 DOI: 10.1155/2018/9153496] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/18/2017] [Revised: 01/30/2018] [Accepted: 02/19/2018] [Indexed: 11/27/2022]
Abstract
Introduction All adult medulloblastoma (AMB) patients should be treated with craniospinal irradiation (CSI) postoperatively. Because of the long irradiation range, multiple radiation fields must be designed for conventional radiotherapy technology. CSI can be completed in only one session with helical tomotherapy (HT). We evaluated the dose of HT, volumetric intensity modulated arc therapy (VMAT), and three-dimensional conformal radiotherapy (3D-CRT) of AMB and the results of 5 cases of AMB treated with HT. Methods Complete craniospinal and posterior cranial fossa irradiation with HT, VMAT, and 3D-CRT and dose evaluation were performed. And results of 5 cases of AMB treated with HT were evaluated. Results A large volume of tissue was exposed to low dose radiation in the organs at risk (OAR), while a small volume was exposed to high dose radiation with HT. The conformity and uniformity of the targets were good with HT and VMAT, and the volume of targets exposed to high dose with VMAT was larger than that of HT. The uniformity of 3D-CRT was also good, but the dose conformity was poor. The main toxicity was hematologic toxicity, without 4th-degree bone marrow suppression. There was 3rd-degree inhibition in the white blood cells, hemoglobin, and platelets. The three female patients suffered menstrual disorders during the course of radiation. Two female patients with heavy menstruation suffered 3rd-degree anemia inhibition, and 2 patients suffered amenorrhea after radiotherapy. Although menstrual cycle was normal, the third patient was not pregnant. Conclusion CSI with HT is convenient for clinical practice, and the side effects are mild. With good conformity and uniformity, VMAT can also be used for selection in CSI. For poor conformity, 3D-CRT should not be the priority selection for CSI. In female patients, the ovaries should be protected.

Abstract
PURPOSE Adult medulloblastoma is a rare disease treated according to the current pediatric treatment guidelines. This retrospective analysis investigated the clinical outcomes and prognostic factors of adult medulloblastoma patients, who received multimodal therapy at our institution. METHODS Treatment charts of all patients over the age of 15 years of age with de novo medulloblastoma, who had been treated at our institution between 2001 and 2014, were retrospectively analyzed. Patients' demographic parameters, initial symptoms, treatment modalities, toxicities, and survival outcomes were investigated. RESULTS In all, 21 patients with a median age of 30.2 years were identified. The most frequent histologies were desmoplastic and classic, and the most common molecular subtype was sonic hedgehog (SHH). After tumor resection, all patients received craniospinal irradiation (median dose 35.2 Gy) and a boost to the posterior fossa (median dose 19.8 Gy). Simultaneous chemotherapy with vincristine was given to 20 patients and sequential chemotherapy to 15 patients. The most common side effects were hematological toxicities. Median overall survival (OS) has not been reached after a median follow-up of 92 months. Estimated 5‑ and 10-year OS was 89 and 80%, respectively. Estimated 5‑ and 10-year progression-free survival (PFS) was 89 and 81%, respectively. In univariate analysis, a shorter interval between tumor resection and end of irradiation was significantly associated with improved OS and PFS, anaplastic histology with worse OS and PFS. CONCLUSIONS The combined modality treatment showed a good outcome in adults with medulloblastoma. Treatment time was revealed to be prognostic and should be kept as short as possible.

Abstract
PURPOSE We examined national outcomes and patterns of care for pediatric patients with medulloblastoma (MB) in a large observational cohort. METHODS AND MATERIALS Using the National Cancer Database, we evaluated the clinical features and survival outcomes of patients diagnosed with MB. The association between intervention, covariables, and outcome was assessed in a multivariable Cox analysis and through logistic regression analysis. Survival was estimated using the Kaplan-Meier method. RESULTS Among the 4032 patients in the National Cancer Database with pediatric brain tumors, 1300 patients met the inclusion criteria of histologic diagnosis, receipt of chemotherapy and radiation, and age ≤18 years. The median age and follow-up were 8.4 years and 4.5 years, respectively. Five-year survival was 79.0%. In the univariate analysis, inferior outcome (overall survival) was associated with rural residence (hazard ratio [HR], 2.78; 95% confidence interval [CI],1.47-5.29; P < .01) and histology (large cell; HR, 1.78; 95% CI,1.08-2.94; P < .05). In multivariable analysis, both remained significant predictors of survival (large cell: HR, 1.68; P < .05; rural residence: HR, 2.74; P < .01). In 2013, the utilization rate of proton therapy (23% of patients) in the United States surpassed intensity modulate radiation therapy (16%), more frequently for patients with higher income (P < .05) or more favorable insurance status (P < .05). CONCLUSIONS As one of the largest data sets on pediatric MB, the observed variations in treatment intervention and survival outcomes may represent a target for further research.

Abstract
BACKGROUND Medulloblastoma is the most common intracranial malignancy in children; with comprehensive treatment the 5-year overall survival (OS) is now greater than 80 %. Only few studies have addressed the relation of tumor location with patient's prognosis. Based on experiences in our institution, we further classified the tumor location. This study aimed to investigate the impact of tumor location and fourth ventricle infiltration in medulloblastoma (MB) prognosis. METHODS We retrospectively followed all MB patients at the Beijing Tiantan Hospital between 2004 and 2007 to investigate treatment outcomes and prognostic factors in MB patients. The data of 119 patients were collected. Tumor removal was performed in all patients, and all patients received postsurgical radiotherapy or chemotherapy. The patients were subclassified into three subtypes according to tumor location and tumor infiltration into the fourth ventricular floor (V4 floor). The prognostic factors were analyzed using Kaplan-Meier and Cox regression analysis. RESULTS The median follow-up period was 75 months (range, 6-127 months). A total of 65 patients experienced recurrence or progression, and 56 patients were still alive at the time of follow-up. The 5-year progression-free survival (PFS) and overall survival (OS) rates were 47.1 ± 4.6 % and 54.6 ± 4.6 %, respectively. CONCLUSIONS According to the multivariate analysis, large cell and anaplastic (LC/A) subtype, patient age, and metastasis were found to be independent prognostic factors. Tumors with V4 floor infiltration exhibited a trend toward recurrence (P = 0.054). This investigation is the largest single-institution study of MB cases in China. The LC/A subtype, patient age, and metastasis were important prognostic factors. V4 floor infiltration was correlated with metastasis and younger age.

Abstract
BACKGROUND The posterior fossa is the site of many types of tumors, and brain metastases are the most common malignancies in that location among adults. Other brain tumors, such as ependymomas, medulloblastomas, and juvenile pilocytic astrocytomas, mostly occur during childhood and are relatively rare in adults. Most primary malignant brain tumors, such as gliomas and lymphomas, tend to be located in the supratentorial compartment. METHODS This review summarizes prognostic factors, therapeutic management, and molecular data of intra-axial posterior fossa tumors in adults, including ependymomas, medulloblastomas, and pilocytic astrocytomas. RESULTS The literature on intra-axial posterior fossa tumors in adults relies mainly on limited retrospective clinical studies, and such studies employ a wide range of treatment approaches that are usually based on therapies developed specifically for children or for supratentorial brain tumors. CONCLUSIONS The clinical course and surgical outcome of adult patients with intra-axial brain tumors in the posterior fossa are summarized in this review. The prognostic factors and therapeutic management of patients with these tumors are controversial because of their rarity, their heterogeneity, and the lack of sufficient data in the literature.

Abstract
Medulloblastoma (MB) is a highly malignant primary brain tumor, which occurs in the cerebellum or posterior cranial fossa. MB is most commonly identified in children <10 years of age. The disease is rare in adults, affecting patients aged between 30 and 50 years of age, with an incidence of 0.5 cases per 1,000,000 individuals. Extraneural metastases are reported in 7-10% of cases, most commonly involving the bones and more rarely involving the lymph nodes, visceral organs and bone marrow. The current study presents the case of a 36-year-old male who underwent a gross total resection followed by radiation therapy to the craniospinal axis for the treatment of MB. The patient subsequently developed widespread metastasis, which involved the soft tissue of the occipital bone. Subsequently, the patient was administered palliative radiotherapy and initially exhibited a good clinical response. However, the patient succumbed at 18 months post-diagnosis due to dissemination of the disease. The literature on the extraneural metastasis of MB is also reviewed in the current study.
