BACKGROUND Constitutional DICER1 mutations were recently reported to cause familial pleuropulmonary blastoma (PPB). AIM To investigate the contribution and phenotypic spectrum of constitutional and somatic DICER1 mutations to cancer. METHODS AND RESULTS The authors sequenced DICER1 in constitutional DNA from 823 unrelated patients with a variety of(More)
BACKGROUND Supratentorial PNET (sPNET) are rare CNS tumors of embryonal origin arising in children and adults. The treatment of sPNET for all age groups at our cancer center has been based on the management of medulloblastoma (MB), involving neurosurgical debulking followed by cranio-spinal irradiation (CSI) and systemic chemotherapy. METHODS Medical(More)
We report the case of a 7-year-old boy who presented with rapidly advancing airway obstruction secondary to mediastinal T-cell non-Hodgkins lymphoma. His brisk deterioration required transfer to the pediatric intensive care unit and intubation of the trachea. Unforeseen unilateral bronchial involvement led to gas trapping and critical pulmonary(More)
BACKGROUND HIV antiretroviral therapy (ART) is often managed without routine laboratory monitoring in Africa; however, the effect of this approach is unknown. This trial investigated whether routine toxicity and efficacy monitoring of HIV-infected patients receiving ART had an important long-term effect on clinical outcomes in Africa. METHODS In this(More)
Neurocognitive dysfunction is the leading cause of reduced quality of life in long-term survivors of paediatric brain tumours. Radiotherapy is one of the main contributors to neurocognitive sequelae. Current approaches for prevention and reduction of neurocognitive dysfunction include avoidance of radiotherapy in young children and reduction of the(More)
BACKGROUND Cross-resistance after first-line antiretroviral therapy (ART) failure is expected to impair activity of nucleoside reverse-transcriptase inhibitors (NRTIs) in second-line therapy for patients with HIV, but evidence for the effect of cross-resistance on virological outcomes is limited. We aimed to assess the association between the activity,(More)
Patients with Nucleophosmin (NPM)- Anaplastic Lymphoma Kinase (ALK) fusion positive Anaplastic Large Cell Lymphoma produce autoantibodies against ALK indicative of an immune response against epitopes of the chimeric fusion protein. We asked whether ALK-expression in other malignancies induces specific antibodies. Antibodies against ALK were detected in sera(More)
BACKGROUND & AIMS Antioxidant intake can affect both free radical and the nutritional status of children receiving cancer treatment. The aim of this study was to investigate whether children with cancer met their antioxidant requirements. METHODS A prospective observational study was performed at a single hospital in England from June 2008 to February(More)
