Burden of cardiovascular risk factors and cardiovascular disease in childhood cancer survivors: Data from the German CVSS-study.
2018
Aims: The cardiac and vascular late sequelae in long-term survivors of childhood cancer (CVSS)-study aimed to quantify the prevalence of cardiovascular risk factors (CVRF) and cardiovascular disease (CVD) in German childhood cancer survivors (CCS). Methods and results: In the CVSS-study (NCT02181049), 1002 CCS (age range 23-48 years) diagnosed with neoplasia prior to 15 years of age between 1980 and 1990 prospectively underwent a systematic, standardized clinical and laboratory cardiovascular screening, identical to the population-based Gutenberg Health Study (GHS) cohort. For 951 individuals, prevalences of CVRF and CVD were primarily compared to the GHS sample and to two further German po…
Radiation-induced vascular changes in the intracranial irradiation field in medulloblastoma survivors: An MRI study
2019
While survival times after treatment of medulloblastoma are increasing, little is known about radiochemotherapy (RCT)-induced cerebrovascular changes. High resolution vessel wall imaging (VWI) sequences are an emerging tool for the evaluation of cerebrovascular diseases. We performed VWI in medulloblastoma long-term survivors to screen for late sequelae of RCT.Twenty-two pediatric medulloblastoma survivors (mean age 25.8 years (10-53 years); 16.3 years (mean) post primary RCT (range 1-45 years)) underwent 2D VWI-MRI. Vessel wall thickening, contrast enhancement and luminal narrowing were analyzed. The findings were correlated with the patients' radiation protocols.Vessel wall changes were o…
Mental health and health-related quality of life in preschool-aged childhood cancer survivors. Results of the prospective cohort study ikidS-OEVA.
2021
Objectives Long-term survivors of childhood cancer are at increased risk for sequelae such as poor mental health (MH) or impaired health-related quality of life (HrQoL). We aimed to evaluate early adverse effects on MH and HrQoL in young childhood cancer survivors (YCCS) before school entry. Methods In a nationwide prospective cohort study, children with cancer other than brain tumors diagnosed at preschool age and completed cancer treatments were identified from the German Childhood Cancer Registry. The comparison group was children of the same age without a cancer diagnosis who participated in the prospective population-based health survey ikidS. MH problems and HrQoL were assessed by par…
Susceptibility-weighted magnetic resonance imaging of cerebrovascular sequelae after radiotherapy for pediatric brain tumors
2017
Due to sensitive neuroimaging techniques, cerebrovascular complications such as cerebral microbleeds (CMB) and cerebral cavernous malformations (CCM) are increasingly recognized as considerable late effects after treatment for pediatric brain tumor. The aim of this study was to analyze CMB in a cohort of patients after cranial irradiation therapy for medulloblastoma or other pediatric brain tumors using susceptibility-weighted magnetic resonance imaging (SWI).Forty former pediatric brain tumor patients were enrolled in this prospective cross-sectional study and examined by cranial MRI including SWI sequences. Cerebral microbleeds, clinical symptoms and disability were evaluated.Thirty-six (…
Identification of an Immunogenic Medulloblastoma-Specific Fusion Involving EPC2 and GULP1
2021
Medulloblastoma is the most common malignant brain tumor in children. Immunotherapy is yet to demonstrate dramatic results in medulloblastoma, one reason being the low rate of mutations creating new antigens in this entity. In tumors with low mutational burden, gene fusions may represent a source of tumor-specific neoantigens. Here, we reviewed the landscape of fusions in medulloblastoma and analyzed their predicted immunogenicity. Furthermore, we described a new in-frame fusion protein identified by RNA-Seq. The fusion involved two genes on chromosome 2 coding for the enhancer of polycomb homolog 2 (EPC2) and GULP PTB domain containing engulfment adaptor 1 (GULP1) respectively. By qRT-PCR …
TRTH-08. HIGH GRADE NEUROEPITHELIAL TUMOR OF THE CENTRAL NERVOUS SYSTEM WITH BCOR ALTERATION IS SENSITIVE TO IGF1R INHIBITION
2017
High grade neuroepithelial tumor of the central nervous system with BCOR alteration (CNS HGNET-BCOR) is a recently described new tumor entity which was formerly diagnosed with diverse histological diagnoses, for example as ependymoma. This tumor predominantly affects children and has a dismal prognosis. No standard therapies for this entity exist so far. Recently we described the activation of the Sonic hedgehog (SHH) and the WNT signaling pathway in this tumor and described a primary cell culture (PhKh1) isolated from a skull metastasis of a seven years old patient. We also detected a high expression of IGF2, which is known to be required for SHH signaling in medulloblastoma. IGF2 signals …

Hemophagocytic Lymphohistiocytosis in Early Infancy- Pitfall of Differentiation between Hereditary and Infectious Reasons
2018
Abstract Hemophagocytic Lymphohistiocytosis (HLH) is characterized by pathologic immune activation which occurs either as a familial disorder or as an acquired condition. The diagnosis of HLH requires the presence of five out of nine criteria: fever, splenomegaly, pancytopenia, hypertriglyceridemia, hypofibrinogenemia, hemophagocytosis in bone marrow, hyperferritinemia, low or absent natural killer cell activity and high level of soluble interleukin-2 receptor. Here we present a 6-month-old girl with parents from Southern Italy. She suffered from hepatosplenomegaly and a recurrent high fever for 3 months' duration. On admission, she showed neurological symptoms including irritability and ne…
Mortality risk among 5‐year survivors of childhood cancer in Germany—Results from the CVSS study (Cardiac and Vascular late Sequelae in long‐term Sur…
2021
The growing population of long-term childhood cancer survivors is at increased risk for severe, therapy-related late effects and premature mortality. The cardiac and vascular late sequelae in long-term survivors of childhood cancer (CVSS) study is a cohort of patients from Germany diagnosed with a neoplasia prior to 15 years of age in the time period 1980 to 1990. Late mortality was evaluated in a total of 4505 individuals who survived 5 years or more after the initial diagnosis (5-year survivors). Survivors with a second primary tumor were excluded. Standardized mortality ratios (SMRs) were calculated. By December 2014, 400 patients had died. Available cause of death information from 188 i…
