BACKGROUND Current controversies in pediatric intracranial ependymoma include histologic categorization and management. Most of our knowledge of this disease comes from single-institution reports. METHODS A literature search was done, covering the period 1976-1996. The aim of this review is to analyze the prognostic factors reported in the literature over(More)
The presentation, growth patterns, and response to therapy of 11 consecutive children with choroid plexus carcinomas were analyzed, and the results were compared with the outcome reported in other series. Patients were a median of 26 months of age at diagnosis. Two patients had thalamic tumors, one had a posterior fossa primary, and the rest had ventricular(More)
The principal aim of this report is to present the results of multivariate analyses conducted to identify clinical prognostic factors in 92 children aged < 16 years with ependymoma (EPD) retrospectively collected in seven Italian centres. They were treated over a 16-year period (1977-1993). Treatment modalities varied. Surgery and radiotherapy (RT) was the(More)
The peculiar radiological and pathological findings of four pediatric cases admitted to the University Hospital of Padua between 1990 and 2007 are described. In all cases, the contrast-enhanced head and spine magnetic resonance images revealed thickened and abnormally enhancing subarachnoid spaces particularly at the level of basal cisterns and(More)
BACKGROUND For hepatoblastoma (HB) that remains unresectable by partial hepatectomy after chemotherapy, total hepatectomy with orthotopic liver transplantation (LTX) has been advocated as the best treatment option. The role of LTX in the overall management of HB is still, however, unclear. PROCEDURE The results of LTX from the first study of HB by the(More)
OBJECT Some medulloblastomas (MBs) are characterized by extreme nodularity and intranodular nuclear uniformity in a fine fibrillary background. These lesions have also been designated as "cerebellar neuroblastoma." Although numerous reports have been published in which their morphological features have been investigated, only a few studies have been focused(More)
SIOPEL 2 was a pilot study designed to test the efficacy and toxicity of two chemotherapy (CT) regimens, one for patients with hepatoblastoma (HB) confined to the liver and involving no more than three hepatic sectors ('standard-risk (SR) HB'), and one for those with HB extending into all four sectors and/or with lung metastases or intra-abdominal extra(More)
PURPOSE Hepatoblastoma (HB) is a rare malignant liver tumor which occurs almost exclusively in childhood. In the 1970s, survival was approximately 20% to 30%. Since the introduction of cisplatin (PLA) and doxorubicin (DO) into the chemotherapy regimens used to treat these patients, the survival rate has improved dramatically. In most recent studies, primary(More)
The aim of this study was to investigate the prognostic significance of pretreatment patient and tumour characteristics for overall (OS) and event-free (EFS) survival in 154 children affected by hepatoblastoma (HB) in the first prospective liver tumour study run by the International Society of Paediatric Oncology. The pretreatment characteristics studied(More)
Between 1975 and 1989, 45 children with newly diagnosed intracranial ependymomas were treated at the authors' institution. Patients were managed with aggressive surgical resection, followed by postoperative CT or MRI scans to evaluate the extent of resection. Most patients received involved-field radiation therapy, however 10 were treated with craniospinal(More)
