Endocrine dysfunction is highly prevalent among tumors located along the hypothalamic pituitary axis and optic pathway, with manifestations such as precocious puberty, diabetes insipidus, or growth failure presenting initially without neurologic symptoms. Posterior fossa tumors, which are more common in pediatrics, can also present with endocrine dysfunction despite their relatively more distant location due to their propensity for causing hydrocephalus. The various treatment modalities for CNS tumors portend additional risks for developing endocrinopathies. Acute endocrine dysfunction often follows surgery involving the HP axis, while endocrine late effects, particularly following radiation exposure of the HP axis, can develop more insidiously years to decades after completion of treatment. Chemotherapy and newer targeted and immunotherapies can cause peripheral endocrine gland as well as HP axis dysfunction. With an increasing number of childhood cancer survivors in the population, recognition and treatment of endocrine late effects is increasingly important. We review here the common endocrine dysfunction associated with various CNS tumors at diagnosis and as a consequence of their treatment.</div></div>","PeriodicalId":49284,"journal":{"name":"Seminars in Pediatric Neurology","volume":"53 ","pages":"Article 101184"},"PeriodicalIF":2.4,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143808348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this review, we synthesize existing research on the social and cognitive struggles faced by PBTS and the challenges they face forming meaningful, reciprocal friendships. PBTS often have cognitive deficits that hinder their ability to recognize social cues and are at risk of bullying and teasing from peers, which can lead to further social isolation. The role of family support is critical, with strong family bonds serving as an essential protective factor. Social skills interventions have shown promise, yet further research is needed to understand how these interventions can effectively increase the social performance of PBTS with their peers.</div></div>","PeriodicalId":49284,"journal":{"name":"Seminars in Pediatric Neurology","volume":"53 ","pages":"Article 101180"},"PeriodicalIF":2.4,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143808350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most recent 2021 World Health Organization (WHO) Classification of Tumors of the CNS (CNS5) has integrated molecular genetics with traditional histopathology leading to more accurate diagnosis and risk stratification/prognostication with subsequent development of personalized treatment paradigms. Pediatric gliomas are traditionally subdivided into low-grade (pLGG) or high-grade gliomas (pHGG). pLGG tend to have excellent overall survival, however, the disease course maybe characterized by multiple recurrences resulting in significant morbidity. Surgical resection is standard with medical therapy (chemotherapy or oral molecular targeted therapy) reserved in the event of radiographic/symptomatic progression. pHGG have poor overall survival despite intensive multimodality therapy. Ependymomas occur in the infratentorial and supratentorial brain as well as in the spine, with the standard treatment including maximal safe resection with involved field radiation therapy that is curative in two-thirds of patients overall. Medulloblastomas are the most common malignant embryonal CNS tumor arising in the cerebellum and are biologically heterogeneous. Given the risk of CSF dissemination, medulloblastomas require surgery, craniospinal radiation as well as multi agent chemotherapy, an approach that is curative in the majority of patients with non-metastatic disease.
