Fumarate hydratase deficiency (FHD) caused by biallelic alterations of the FH (fumarate hydratase) gene is a rare disorder of the tricarboxylic acid cycle, classically characterized by encephalopathy, profound psychomotor retardation, seizures, a spectrum of brain abnormalities and early death in childhood. Less common milder phenotypes with moderate cognitive impairment and long-term survival have been reported. In addition, heterozygous mutations of the FH gene are responsible for hereditary leiomyomatosis and renal cell cancer (HLRCC)...

Paula Casano Sancho
Thanks to the advances in cancer treatment, the five-year survival rate after childhood cancer has increased up to 80%. Therefore 1/500 young adults will be a survivor. Endocrine sequelae are most common, affecting 40-60% of survivors. The most frequent sequelae include growth failure and gonadal and thyroid diseases. Sequelae occur more frequently in survivors from central nervous system tumors, leukemia, and lymphoma. Their development will depend on the type of cancer, its location, age at diagnosis, and treatment administered...

Importance: Childhood cancer survivors may be reluctant to make changes in their employment because of access to health insurance. Objective: To examine the prevalence of "job lock" (staying at a job to keep work-related health insurance) in a sample drawn from an established, multi-institutional cohort of full-time employed childhood cancer survivors compared with a random sample of siblings and to explore factors associated with job lock among cancer survivors...

Neuroblastoma is the most common extracranial solid childhood tumor. Despite the availability of advanced multimodal therapy, high-risk patients still have low survival rates. p21-activated kinase 4 (PAK4) has been shown to regulate many cellular processes in cancer cells, including migration, polarization and proliferation. However, the role of PAK4 in neuroblastoma remains unclear. In the present study, we demonstrated that PAK4 was overexpressed in neuroblastoma tissues and was correlated with tumor malignance and prognosis...

BACKGROUND: Childhood cancer survivors have increased risk for cardiovascular disease. We sought to describe the trends of cardiovascular mortality (CVM) among survivors of childhood cancers in the United States. METHODS: We used the Surveillance, Epidemiology, and End-Results 18 database to identify all children who were diagnosed with childhood cancers between 1973 and 2013. We describe the incidence of CVM in four eras (era 1: 1973-1982, era 2: 1983-1992, era 3: 1993-2002, and era 4: 2003-2013)...

STUDY QUESTION: Do young adult survivors of childhood cancer know their fertility status, in the context of their parenthood goals and screening for gonadal functioning? SUMMARY ANSWER: While 80% of survivors (who were without children) wanted children in the future, most did not know their fertility status, and screening for gonadal functioning was underutilized. WHAT IS KNOWN ALREADY: Survivors of childhood cancer are at risk for infertility, but fertility counseling and assessment are underutilized...

The etiology of childhood cancers remains largely unknown, especially regarding environmental and behavioral risk factors. Unpacking the association between socioeconomic status (SES) and incidence may offer insight into such etiology. We tested associations between SES and childhood cancer incidence in a population-based case-cohort study (source cohort: Minnesota birth registry, 1989-2014). Cases, 0-14 years, were linked from the Minnesota Cancer Surveillance System to birth records through probabilistic record linkage...

BACKGROUND/AIMS: Results from recent studies suggest that extremely low frequency magnetic fields (ELF-MF) interfere with intracellular signaling pathways related to proliferative control. The mitogen-activated protein kinases (MAPKs), central signaling components that regulate essentially all stimulated cellular processes, include the extracellular signal-regulated kinases 1/2 (ERK1/2) that are extremely sensitive to extracellular cues. Anti-phospho-ERK antibodies serve as a readout for ERK1/2 activation and are able to detect minute changes in ERK stimulation...

Transcription factor AP-2β (TFAP2B) regulates embryonic organ development and is overexpressed in alveolar rhabdomyosarcoma, a rare childhood malignancy. Gene expression profiling has implicated AP-2β in breast cancer (BC). This study characterizes AP-2β expression in the mammary gland and in BC. AP-2β protein expression was assessed in the normal mammary gland epithelium, in various reactive, metaplastic and pre-invasive neoplastic lesions and in two clinical BC cohorts comprising >2000 patients. BCs from various genetically engineered mouse (GEM) models were also evaluated...

BACKGROUND: Pediatric oncologists are often faced with situations in which parents or guardians refuse recommended treatment for curable childhood cancer. Deciding how to proceed in such situations is an ethical dilemma. The aim of this article is to consider optimal approaches when parents are strongly against oncological treatment, potentially compromising their childrens rights for health care and to the chance for cure. CASES: In this paper, we report two cases of treatment refusal from our department and the impact of such decisions on the children themselves...

Rhabdomyosarcoma (RMS) is a malignant tumor of skeletal muscle origin and frequently involves the head and neck region. It represents the second most common pediatric soft tissue sarcoma and accounts for 3% of all childhood cancers. Here, we report a case of embryonal RMS presenting as a right-sided facial swelling in a 7-year-old boy. Histologically, the tumor consisted of classic embryonal rhabdosarcomatous areas with metaplastic cartilage, in both initial biopsy and final resection specimens. Cartilaginous metaplasia arising in the background of RMS is a rare finding, thus raising a diagnostic challenge...

Survivors of childhood cancer are at increased risk for therapy-related morbidities and mortality. Although the demographic and clinical factors predicting the risk for long-term effects of cancer therapy are well known, the impact of genetic risk for specific late effects is less clearly defined. Here, we review the extant literature and recent research describing genetic modifiers to risk for the more common late effects of childhood cancer therapy. Results of this research support the need for clinical trials that attempt to further refine risk prediction by incorporating genetic testing into existing algorithms that are primarily based on clinical and demographic factors...

BACKGROUND: The reported incidence of childhood cancer in upper-middle-income South Africa (SA) is much lower than in high-income countries, partly due to under-diagnosis and under-reporting. Documented survival rates are disturbingly low, prompting an analysis of potential factors that may be responsible. OBJECTIVES: To determine final-year medical students' level of knowledge of early warning signs of childhood cancer and whether a correlation existed between test scores and participants' age, gender and previous exposure to a person with cancer...
