ABSTRACT

Los tumores del sistema nervioso central representan la segunda enfermedad oncológica más habitual en niños y adolescentes. Entre los tumores intracraneales, los de células germinales son infrecuentes. Los síntomas que desencadenan son cefalea, náuseas, vómitos, déficits hormonales, alteraciones visuales, pérdida de peso, pobre crecimiento y pubertad precoz. Menos frecuentemente, producen trastornos del movimiento o psiquiátricos. Algunos de estos tumores pueden ser asintomáticos un largo período, lo que desencadena un diagnóstico tardío.Se presenta a una paciente femenina de 14 años con pérdida de peso y falla del crecimiento, con diagnóstico erróneo de trastorno de la conducta alimentaria. Tras estudios pertinentes, se arribó al diagnóstico de germinoma del sistema nervioso central. Al ser esta patología infrecuente y de presentación variable, requiere alto sentido de alerta por parte de la familia involucrada y del equipo de salud para evitar retrasos en el diagnóstico y el tratamiento


Central nervous system tumors are the second most frequent oncological disease among children and teenagers. Among the intracranial tumors, the germ cells ones are infrequent. The symptoms they cause are headaches, nausea and vomiting, hormonal deficits, visual disturbances, weight loss, poor growth and early puberty. Less frequently, they produce movement or psychiatric disorders. Some of these tumors can be asymptomatic for a long period leading to a late diagnosis.The case of a 14-year-old female patient is presented. She showed weight loss and growth failure, with wrong diagnosis of eating disorder. After proper study methods, we arrived to central nervous system germinoma diagnosis. Because this pathology is rare and has a variable form of presentation, it requires that the family involved and the health team to be alert, to avoid delays in diagnosis and treatment.

ABSTRACT

Objective: to assess the nutritional status of children with brain tumors on hospital admission and to verify whether the nutritional status varies according to the type of tumor. Methods: anthropometric data of 30 children between 2 and 10 years old, of both sexes, with brain tumors and admitted to a hospital in the city of São Paulo, Brazil, were evaluated. Secondary data collection allowed to assess and classify the Z-scores of the body mass index, percentage of adequacy of the triceptal skinfold and the arm muscle circumference, carried out between the years 2004 and 2011. Results: the frequencies of brain tumors were: 33.3% astrocytic, 40% embryonal, 10% of the seal region and 16.6% ependimals. The median age and body mass index Z scores were 5.5 years (4.0 and 7.0) and 0.66 SD (- 1.41 and 0.87), respectively. The median percentage of adequacy of arm muscle circumference was 98% (88.9 and 103.2) and the triceptal skinfold was 83.2% (57.0 and 106.6). As for nutritional status, 21 (70%) of the children were eutrophic; 7 (23.3%) overweight and 2 (6.7%) with malnutrition/wasting showing no significant difference between groups of brain tumors (p = 0.721). The percentages of adequacy of the triceptal skinfold and of the arm muscle circumference also showed no significant difference between the different types of brain tumors (p = 0.865 and p = 0.860, respectively). Conclusion: at the time of hospital admission, the children were in good nutritional status, regardless of the type of brain tumor. (AU)

ABSTRACT

Resumen Objetivo: Analizar características por resonancia magnética (RM) de gliomas IDH-mutados (grado II y III) en base a parámetros cualitativos, a fin de valorar el rendimiento del signo del mismatch T2-FLAIR y otras características morfológicas de los tumores, en predecir el estado del 1p/19q y su reproducibilidad interobservador. Métodos Estudio retrospectivo, descriptivo y analítico sobre una cohorte de 53 gliomas IDH-mutados (grado II y III) y molecularmente definidos respecto al 1p/19q, seleccionados a partir de la base de datos de la institución, durante el periodo 2014- 2019. Dos neuroradiólogos evaluaron características imagenológicas de forma independiente y enmascarada al diagnóstico: mismatch T2-FLAIR, localización tumoral, bordes, señal, infiltración cortical e inhomogeneidad en T2. Los casos discordantes fueron evaluados por un tercer neuroradiólogo de mayor experiencia. Resultados: Treinta de 53 (56,6%) gliomas fueron no codelecionados, y 23/53 (43,4%) codelecionados. El signo del mismatch T2-FLAIR fue positivo en 16/53 (30,18%) pacientes, 15/16 (93,75%) no codelecionados y 1/16 (6,25%) codelecionado (Exacto de Fisher p = <,0001). Los dos evaluadores demostraron una concordancia interobservador casi perfecta para ese signo, κ =,907 (95% CI, 0,781 a 1,0). La especificidad y el valor predictivo positivo del signo para predecir la ausencia de la codeleción fue de un 95,7% y un 93,8% respectivamente. Discusión: La reciente actualización en la clasificación de los gliomas los clasifica acorde a su perfil molecular. En los últimos años, varios investigadores han estudiado características morfológicas por RM de los tumores con la intención de predecir las características moleculares de los mismos. Conclusión: En nuestra población, el signo del mismatch T2-FLAIR es el único biomarcador radiológico que muestra asociación estadísticamente significativa en predecir la ausencia de codeleción en los gliomas IDH-mutados (grado II y III), con una alta especificidad y un alto valor predictivo positivo.


Abstract Objective: To analyze magnetic resonance (MR) characteristics of IDH-mutated gliomas (grades II/III) utilizing qualitative parameters with the goal of assessing the performance of the T2-FLAIR mismatch sign and other morphological characteristics of tumors in predicting the 1p/19q co-deletion status as well as inter-observer reproducibility. Methods: Retrospective and descriptive study analyzing a cohort of 53 IDH-mutated lower-grade (grades II/III) gliomas with known 1p/19q co-deletion status. Patients meeting selection criteria for this study were taken from our institutional data from 2014-2019. Two neuroradiologists assessed the following imaging characteristics independently, and blinded from the diagnosis: T2-FLAIR mismatch, tumor location, borders, signal characteristics, cortical infiltration and T2* inhomogeneity. In the event of discordant interpretations, a third senior neuroradiologist also evaluated the case. Results: 23 of the 53 (43.4%) gliomas demonstrated 1p/19q co-deletion and 30 of 53 (56.6%) did not. T2-FLAIR mismatch was positive in 16 of 53 cases (30.2%) with 15 of 16 (93.8%) demonstrating no co-deletion and 1/16 (6.25%) with co-deletion (Fisher's exact p = < .0001). The two readers showed an almost perfect interreader agreement for this sign κ = 0.907 (95% CI, 0.781 to 1.0). Specificity and positive predictive value of the sign to predict the absence of co-deletion was 95.7% and 93.8% respectively. Discussion: The recent update in classification of lower-grade gliomas segregates gliomas according to molecular profile. In the recent past, many researchers have studied MR morphologic characteristics of these tumors with the intention of predicting molecular features of said tumors Conclusion: In our patient population, T2-FLAIR mismatch sign is the only radiologic biomarker that shows statistically significant association with the absence of 1p/19q co-deletion in lower-grade gliomas, with high specificity and positive predictive value.

ABSTRACT

This work aimed to research the function of MARVEL domain-containing protein 1 (MARVELD1) in glioma as well as its functioning mode. Bioinformatics analysis was utilized to assess the MARVELD1 expression in glioma tissues and its relationship with grade and prognosis, based on The Cancer Genome Atlas (TCGA), Genotype-Tissue Expression (GTEx), and Chinese Glioma Genome Atlas (CGGA) databases. Cell Counting Kit-8 (CCK-8), colony formation, and Transwell assays were carried out to determine the impact of MARVELD1 on malignant biological behavior of glioma, such as proliferation, invasion, and migration. qRT-PCR was carried out to test the mRNA level of MARVELD1. Western blot assay was performed to measure the protein expression of MARVELD1 and JAK/STAT pathway-related proteins. MARVELD1 was expressed at high levels in glioma tissues and cell lines. Kaplan-Meier survival analysis revealed that the higher MARVELD1 expression, the shorter the survival time of patients with glioma. Also, the MARVELD1 expression in WHO IV was significantly enhanced compared to that in WHO II and WHO III. Furthermore, the functional analysis of MARVELD1 in vitro revealed that knockdown of MARVELD1 in U251 cells restrained cell proliferation, migration, and invasion, while up-regulation of MARVELD1 in U87 cells presented opposite outcomes. Finally, we found that JAK/STAT signaling pathway mediated the function of MARVELD1 in glioma. MARVELD1 contributed to promoting the malignant progression of glioma, which is the key driver of activation of JAK/STAT signaling pathway in gliomas.

ABSTRACT

Genomic studies have provided insights into molecular subgroups and oncogenic drivers of pediatric brain tumors (PBT) that may lead to novel therapeutic strategies. Participants of the cohort Pediatric Brain Tumor Atlas: CBTTC (CBTTC cohort), were randomly divided into training and validation cohorts. In the training cohort, Kaplan-Meier analysis and univariate Cox regression model were applied to preliminary screening of prognostic genes. The LASSO Cox regression model was implemented to build a multi-gene signature, which was then validated in the validation and CBTTC cohorts through Kaplan-Meier, Cox, and receiver operating characteristic curve (ROC) analyses. Also, gene set enrichment analysis (GSEA) and immune infiltrating analyses were conducted to understand function annotation and the role of the signature in the tumor microenvironment. An eight-gene signature was built, which was examined by Kaplan-Meier analysis, revealing that a significant overall survival difference was seen, either in the training or validation cohorts. The eight-gene signature was further proven to be independent of other clinic-pathologic parameters via the Cox regression analyses. Moreover, ROC analysis demonstrated that this signature owned a better predictive power of PBT prognosis. Furthermore, GSEA and immune infiltrating analyses showed that the signature had close interactions with immune-related pathways and was closely related to CD8 T cells and monocytes in the tumor environment. Identifying the eight-gene signature (CBX7, JADE2, IGF2BP3, OR2W6P, PRAME, TICRR, KIF4A, and PIMREG) could accurately identify patients' prognosis and the signature had close interactions with the immunodominant tumor environment, which may provide insight into personalized prognosis prediction and new therapies for PBT patients.

ABSTRACT

Inflammatory Myofibroblastic Tumor (IMT) is a rare pathologic entity that was first described in 1973. This lesion is most commonly found in the lungs, but other organs' involvement has also been reported. Intracranial location of Inflammatory Myofibroblastic Tumor is rare, and the first case was reported in 1980. An intriguing fact about the intracranial IMT is its resemblance with meningioma on clinical presentation and neuroimaging. We came across a case of intracranial Inflammatory Myofibroblastic Tumor (IIMT) in a 27-year-old male who presented with recurrent episodes of seizures and was diagnosed as meningioma on neuroimaging. The lesion did not subside with medical management and kept on progressing in size. The patient had to undergo surgery, and diagnosis of Inflammatory Myofibroblastic Tumor was ascertained on histopathology. This 'surprise' diagnosis prompted us to review the literature on all cases of IIMTs reported to date to better understand the entity and its implications. In this review article, we present our observations regarding various studied parameters, including patient profile, clinical presentation, site of involvement, focality of the lesion, special associations, and lines of management of the 49 published cases of IIMTs.

ABSTRACT

Antecedentes: El Glioblastoma (GB) o astrocitoma grado IV, es un tumor agresivo que se origina de células gliales, con alto grado de malignidad, prevalencia menor al 1% en fosa posterior e incidencia menor al 0.5% de todos los GB. Actualmente se describen alrededor de 75 casos a nivel mundial. Descripción del caso clínico: Femenina, 24 años, referida a emergencia de Neurocirugía del Hospital Escuela Universitario, presentó cefalea holocraneana intensa, vómitos, náuseas, visión borrosa, vértigo y anorexia. Al examen neurológico mostró discreta adiadococinesia derecha y signos de papiledema. La tomografía axial computarizada cerebral evidenció lesión heterogénea en vermis extendido a hemisferio cerebeloso derecho, por lo que se realizó craniectomía suboccipital, abordaje transcerebelar, con citorreducción tumoral, encontrando masa vascularizada con componente quístico. Estudio anatomopatológico evidenció glioblastoma multiforme variante de células gigantes, confirmado con tinción de inmunohistoquímica (PFGA, CD34+ y vimentina). Paciente con buena evolución clínica postquirúrgica, egresada sin déficit neurológico. 16 meses después, presentó síndrome de recidiva tumoral y complicaciones, por lo que se reintervino en 4 ocasiones, posterior a recibir 30 dosis de radioterapia y 12 ciclos de quimioterapia, se reingresó con deterioro neurológico progresivo, signos meníngeos y síndrome de Parinaud, escala de Karnofsky (30 puntos), realizándose derivación ventrículo-peritoneal por compresión del IV ventrículo e hidrocefalia obstructiva secundaria, luego desarrolló neumonía intrahospitalaria, falleciendo a las dos semanas. Conclusiones: Es importante identificar la variante biológica del glioblastoma de forma temprana, para determinar pronóstico y acciones terapéuticas que influirán en la calidad de vida, así como la supervivencia...(AU)

ABSTRACT

ABSTRACT The anesthesia for awake craniotomy (AC) is a consecrated anesthetic technique that has been perfected over the years. Initially used to map epileptic foci, it later became the standard technique for the removal of glial neoplasms in eloquent brain areas. We present an AC anesthesia technique consisting of three primordial times, called awake-asleep-awake, and their respective particularities, as well as delve into the anesthetic medications used. Its use in patients with low and high-grade gliomas was favorable for the resection of tumors within the functional boundaries of patients, with shorter hospital stay and lower direct costs. The present study aims to systematize the technique based on the experience of the largest philanthropic hospital in Latin America and discusses the most relevant aspects that have consolidated this technique as the most appropriate in the surgery of gliomas in eloquent areas.


RESUMO A anestesia para craniotomia em paciente acordado (CPA ou awake craniotomy) é técnica anestésica consagrada e aperfeiçoada ao longo dos últimos anos. Utilizada inicialmente para mapeamento de focos epilépticos, consolidou-se posteriormente como técnica padrão para a remoção de neoplasias de origem glial em áreas eloquentes cerebrais. A técnica de anestesia CPA apresentada constitui-se em três tempos primordiais denominados acordado-dormindo-acordado (asleep-awake-asleep) e respectivas particularidades, assim como o manejo quanto às medicações anestésicas utilizadas de forma pormenorizada. A utilização em gliomas de baixo e de alto grau se demonstrou favorável para a ressecção de tumores dentro dos limites funcionais dos pacientes, com menor tempo de internação hospitalar e de custos diretos. O presente estudo visa realizar a sistematização da técnica baseada na experiência do maior Hospital Filantrópico da América Latina e discute os aspectos mais relevantes que consolidaram essa técnica como a mais adequada na cirurgia dos gliomas em áreas eloquentes.

ABSTRACT

Resumen El cáncer diferenciado de tiroides generalmente se acompaña de una supervivencia a largo plazo. Sin embargo, en algunos casos pueden desarrollarse metástasis a distancia y, entre ellas, las localizaciones cerebrales son de mal pronóstico. El objetivo de esta presentación es comunicar el caso clínico de una mujer de 65 años que consultó por diplopía en la mirada vertical que había aparecido un mes antes. La resonancia magnética mostró una gran masa a nivel del cóndilo occipital. Se realizó el diagnóstico de tumor cerebral primario, por lo que fue operada dos veces con resección tumoral incompleta. El estudio histopatológico confirmó una lesión metastásica de carcinoma de tiroides. Se realizó una tiroidectomía total con resección de un cáncer papilar de la variante folicular. Luego, fue tratada con éxito con pequeñas cantidades repetitivas de yodo radiactivo para una dosis total acumulada de 325 mCi 131I, con una supervivencia a largo plazo.


Abstract Differentiated thyroid cancer is generally accompanied by a long term survival. However,in some cases distant metastases can develop and among them, brain localizations are of poor prognosis. The aim of this presentation is to communicate the clinical case of a 65 year-old woman who consulted for diplopia in vertical gaze which had appeared one month earlier. MRI showed a big mass at the level of the occipital condyle. Diagnosis of primary brain tumor was made so she was operated twice with incomplete tumor resection. The pathological study was confirmatory of a metastatic lesion of thyroid carcinoma. A total thyroidectomy with resection of a papillary cancer of the follicular variant was performed. Then, she was successfully treated with small repetitive radioiodine amounts for a total accumulated dose of 325 mCi 131I, with a long-term survival.

ABSTRACT

Abstract Cerebellar astrocytoma (low-grade glioma) is the most frequent tumor of the Central Nervous System in pediatric age, corresponding to 10-20% of brain tumors, having its maximum incidence at 5 years. Brain tumors are the second cause of death at this age, behind leukemias. Its most frequent clinic is headache with vomiting which can worsen in the morning and awaken the patient at night. The most frequent ophthalmological clinic is papilledema and involvement of the cranial nerve VI. In our case we present an atypical presentation (cranial IV), in which a quick derivation favored a better prognosis.


Resumo O astrocitoma cerebelar (glioma de baixo grau) é o tumor mais frequente do Sistema Nervoso Central em idade pediátrica, correspondendo a 10-20% dos tumores cerebrais, tendo sua incidência máxima em 5 anos. Os tumores cerebrais são a segunda causa de morte nesta idade, atrás das leucemias. Sua clínica mais frequente é a cefaleia com vômitos que podem piorar pela manhã e despertar o paciente à noite. A clínica oftalmológica mais frequente é o papiledema e o envolvimento do nervo craniano VI. Em nosso caso apresentamos uma apresentação atípica (IV craniana), em que uma derivação rápida favoreceu um melhor prognóstico.

ABSTRACT

SUMMARY OBJECTIVES HOXB2 is a new prognostic indicator for lung cancer. But it is unclear whether HOXB2 holds an effect in glioblastoma (GBM) progression. The purpose of this article was to probe the influences of HOXB2 on GBM pathogenesis. METHODS HOXB2 expression level and prognostic power in GBM patients were analyzed. Then the mRNA and protein expression levels of HOXB2 in GBM cell lines were tested by qRT-PCR and western blotting. Cell proliferation, invasion, and migration were determined by CCK8 and transwell assay, severally. The protein levels of PI3K/AKT-pathway associated proteins were analyzed by western blotting. RESULTS The results indicated that HOXB2 was distinctly overexpressed in GBM patients and high expression of HOXB2 was related to a poor prognosis. Moreover, the expression of HOXB2 was higher in all GBM cell lines U251, U-87MG, GOS-3 than that in HEB cells (normal control). Meanwhile, decreased expression of p-PI3K and p-AKT were identified after HOXB2 knockdown. CONCLUSIONS These data demonstrated that HOXB2 had a vital role in GBM progression and could serve as a promising target for GBM treatment.


RESUMO OBJETIVOS A HOXB2 é um novo indicador prognóstico para o câncer de pulmão. Mas não está claro se a HOXB2 tem algum efeito na progressão do glioblastoma (GBM). O objetivo deste artigo foi sondar as influências da HOXB2 na patogênese do GBM. MÉTODOS Foram analisados o nível de expressão e o poder prognóstico da HOXB2 em pacientes com GBM. Em seguida, os níveis de expressão proteica e mRNA da HOXB2 em linhagens de células de GBM foram testados por qRT-PCR e western blotting. A proliferação, a invasão e migração celular foram determinadas por CCK8 e ensaios transwell, várias vezes. Os níveis proteicos das proteínas associadas à via PI3K/AKT foram analisados pelo método western blotting. RESULTADOS Os resultados indicaram que havia uma clara superrexpressão da HOXB2 em pacientes com GBM e que a alta expressão da HOXB2 estava relacionada a um prognóstico negativo. Além disso, a expressão da HOXB2 foi mais elevada em todas as linhagens de células do GBM U251, U-87MG, GOS-3 do que nas células HEB (controle normal). Entretanto, a diminuição da expressão de P-PI3K e p-AKT foi identificada após a redução da expressão da HOXB2. CONCLUSÕES Esses dados demonstram que a HOXB2 desempenha um papel vital na progressão do GBM, podendo ser um alvo promissor para o tratamento do GBM.

ABSTRACT

RESUMEN A nivel mundial se estiman que cada año se diagnostican aproximadamente 650 000 nuevos casos de cáncer escamoso de cabeza y cuello. Ocasionan 300 000 muertes y dos tercios de estos casos se originan en países en vías de desarrollo. Se presentó un caso de un paciente atendido en consulta a causa de crecimiento acelerado de la región frontotemporoparietal derecha, acompañado de sintomatología neurológica correspondiente a una afección funcional de los lóbulos parietal y temporal derecho. Se le realizó exámenes imagenológicos y biopsia por punción de la lesión, lo que arrojó un carcinoma escamoso como variedad histológica de la tumoración (AU).


ABSTRACT It is thought that around 650 000 new cases of head and neck squamous tumors are diagnosed in the world every year. They cause 300 000 deaths and two thirds of these cases are originated in developing countries. We presented the case of a patient who assisted the consultation due to the fast growth of the right frontotemporal parietal region, accompanied with neurological symptomatology corresponding to a functional disorder of the right parietal and temporal lobes. Imaging studies and a biopsy by lesion puncture were performed. It showed a squamous carcinoma as histological variant of the tumor (AU).

ABSTRACT

Resumen: Los oligodendrogliomas anaplásicos son gliomas infiltrantes grado III de la organización mundial de la salud (OMS). Son tumores poco frecuentes y representan el 5-10% de todas las neoplasias intracraneales primarias. Su incidencia es de 0.3 por 100.000 habitantes por año en Estados Unidos. Con frecuencia se presentan en adultos entre los 40-60 años de edad. Los síntomas principales pueden ser déficit motor, déficit cognitivos y síntomas de aumento de la presión intracraneal. Su comportamiento en resonancia magnética muestra un aspecto heterogéneo con necrosis, degeneración quística y hemorragia intratumoral. Las presentaciones quísticas extensas son poco frecuentes. Reportamos el caso de un oligodendroglioma anaplásico de aspecto predominantemente quístico en una mujer joven.


Abstract: Anaplastic oligodendrogliomas are grade III infiltrating gliomas of the World Health Organization (WHO). They are rare tumors and represent 5-10% of all primary intracranial neoplasms. Its incidence is 0.3 per 100.000 inhabitants per year in the United States. They often occur in adults between 40-60 years of age. The main symptoms may be motor deficit, cognitive deficits and symptoms of increased intracranial pressure. Its behavior in MRI shows a heterogeneous appearance with necrosis, cystic degeneration and intratumoral hemorrhagic. Extensive cystic presentations are rare. We report the case of an anaplastic oligodendroglioma of predominantly cystic appearance in a young woman.

ABSTRACT

Abstract Background: Central nervous system (CNS) gliosarcoma (GSM) is a rare primary neoplasm characterized by the presence of glial and sarcomatous components. Objective: In this report, we describe the clinical and neuroimaging aspects of three cases of GSM and correlate these aspects with pathological findings. We also provide a brief review of relevant literature. Methods: Three patients were evaluated with magnetic resonance imaging (MRI), and biopsies confirmed the diagnosis of primary GSM, without previous radiotherapy. Results: The analysis of conventional sequences (T1, T1 after contrast injection, T2, Fluid attenuation inversion recovery, SWI and DWI/ADC map) and advanced (proton 1H MR spectroscopy and perfusion) revealed an irregular, necrotic aspect of the lesion, peritumoral edema/infiltration and isointensity of the solid component on a T2-weighted image. These features were associated with irregular and peripheral contrast enhancement, lipid and lactate peaks, increased choline and creatine levels in proton spectroscopy, increased relative cerebral blood volume (rCBV) in perfusion, multifocality and drop metastasis in one of the cases. Conclusion: These findings are discussed in relation to the general characteristics of GSM reported in the literature.


Resumo Introdução: O gliossarcoma (GSM) do sistema nervoso central (SNC) é uma neoplasia primária rara, caracterizada pela presença de componentes gliais e sarcomatosos. Objetivo: Nosso objetivo é descrever os aspectos clínicos e de neuroimagem de três casos com este diagnóstico e correlacioná-los com os achados patológicos. Também foi realizada uma breve revisão da literatura relevante. Métodos: Três pacientes foram avaliados por ressonância magnética (RM), e biópsias confirmaram o diagnóstico de GSM primário, sem radioterapia prévia. Resultados: Foram analisadas as sequências convencionais (T1, T1 após injeção de contraste, T2, FLAIR-fluid attenuation inversion recovery, SWI, DWI/mapa ADC) e as sequências avançadas (espectroscopia de prótons 1H e perfusão), observando-se aspecto necrótico e irregular da lesão, edema/infiltração peritumoral, isointensidade do componente sólido em T2, associada a realce irregular e periférico pelo meio de contraste, pico de lípides e de lactato e aumento dos níveis de colina e creatina na espectroscopia de prótons, aumento do volume sanguíneo cerebral relativo (rCBV) na perfusão, multifocalidade e "drop" mestástase em um dos casos. Conclusão: O presente estudo descreve características do GSM, discutindo as informações na literatura científica, ilustrando algumas particularidades desses tumores.
