Survivors of infant atypical teratoid/rhabdoid tumors present with severely impaired cognitive functions especially for fluid intelligence and visual processing: data from the German brain tumor studies.

BACKGROUND: The contribution of tumor type, multimodal treatment, and other patient-related factors upon long-term cognitive sequelae in infant brain tumor survivors remains undefined. We add our retrospective analysis of neuropsychological and quality of survival (QoS) outcome data of survivors of atypical teratoid/rhabdoid tumors (ATRT) and extracranial malignant rhabdoid tumors of the soft tissues (eMRT) and kidneys (RTK) treated within the same framework. Neuropsychological data from children with ATRT were compared to data from children with non-irradiated low-grade glioma (LGG). PATIENTS AND METHODS: Following surgery, patients (0-36 months at diagnosis) had received radio-chemotherapy (up to 54 Gy; ATRT: n = 13; eMRT/RTK: n = 7), chemotherapy only (LGG: n = 4; eMRT/RTK: n = 1) or had been observed (LGG: n = 11). Neuropsychological evaluation employing comparable tests was performed at median 6.8 years (ATRT), 6.6 years (eMRT/RTK), and 5.2 years (LGG) post diagnosis. RESULTS: We detected sequelae in various domains for all tumor types. Group comparison showed impairments, specifically in fluid intelligence (p = .041; d = 1.11) and visual processing (p = .001; d = 2.09) in ATRT patients when compared to LGG patients. Results for psychomotor speed and attention abilities were significantly below the norm for both groups (p < .001-.019; d = 0.79-1.90). Diagnosis predicted impairments of cognitive outcome, while sex- and age-related variables did not. QoS outcome for all rhabdoid patients displayed impairments mainly in social (p = .008; d = 0.74) and school functioning (p = .048; d = 0.67), as well as lower overall scores in psychosocial functioning (p = .023; d = 0.78) and quality of life (p = .006; d = 0.79) compared to healthy controls. CONCLUSION: Survivors of infant ATRT experience various late effects in cognition and QoS following multimodal treatment, while infant LGG patients without radiotherapy demonstrated comparable impairments in psychomotor and attention abilities. Early onset and multimodal treatment of rhabdoid tumors require close monitoring of neuropsychological and QoS sequelae.

School and kindergarten attendance and home schooling of pediatric cancer patients before and during the SARS-CoV-2 pandemic: results of a survey of the German Society for Pediatric Oncology and Hematology.

In this multicenter survey (July 07 to August 08, 2020) in pediatric oncology centers (POCs) belonging to the German Society for Pediatric Oncology and Hematology (GPOH), 36 POCs participated (response rate 70.6%). Home schooling practice was judged as satisfying by 79% prior to and by 38% during the pandemic (P=0.0007). The individual risk of a SARS-CoV-2 infection and the risk of transmission to other patients/caregivers were arguments against attendance. Most POCs recommended regular social participation/school attendance after the end of intensive therapy. 81% stated that persisting restrictions result in serious negative psychosocial consequences for the patients and their families. In-hospital school education, home schooling and re-attendance of school and kindergarten among pediatric cancer patients have suffered a severe setback during the SARS-CoV-2 pandemic. Continuous communication and education concerning protective measures as well as an individual risk assessment are required to avoid the detrimental exclusion of pediatric oncology patients from kindergarten and school.
