Cognitive and psychological disorders are among the most frequently observed sequelae in brain tumor survivors. The goal of this work was to verify the presence of these disorders in a group of children and adolescents diagnosed with brain tumor before age 18 years, differentiate these disorders according to age of assessment, identify correlations between(More)
PURPOSE Neither hormone-related nor genetics risk factors have been associated with the development of highly proliferative HER2-positive breast carcinomas. Because the majority of HER2-positive tumors present the amplification of the oncogene, we asked whether genomic instability triggered by irradiation might be involved in the induction of(More)
Intracranial germ cell tumors are rare tumor entities in childhood and adolescents. Extra- and intracranial germ cell tumors are identical in their histologic pattern and occur in preferential midline localizations such as the pineal and the suprasellar region. Germ cell neoplasms show increasing incidence rates over the last 30 years. The majority of(More)
Anaplastic lymphoma kinase (ALK) is a receptor tyrosine kinase predominantly expressed in the developing nervous system. Recently, mutated ALK has been identified as a major oncogene associated with familial and sporadic neuroblastomas (NBL). Yet, a direct correlation between endogenous expression level of the ALK protein, oncogenic potential, and clinical(More)
Neuroblastoma cells have been shown to express molecularly defined tumor-associated antigens, which could represent potential targets of T and/or B cell-mediated immunity. However, the existence of a spontaneous immune response to such tumor antigens in neuroblastoma patients has yet to be investigated. In the present work we addressed the issue of whether(More)
Childhood malignant gliomas are rare, but their clinical behavior is almost as aggressive as in adults, with resistance to therapy, rapid progression, and not uncommonly, dissemination. Our study protocol incorporated sequential chemotherapy and high-dose thiotepa in the preradiant phase, followed by focal radiotherapy and maintenance with vincristine and(More)
Patients with diffuse pontine gliomas have a median survival of less than one year and represent a challenge for pediatric oncologists, prompting them to attempt experimental therapies. From 1987 to 2005, 62 children with diffuse pontine glioma, not amenable to curative surgery, were treated according to four successive pilot protocols: (1) concomitant(More)
'impiego delle immunoglobuline endovena (IVIG) nell'anemia emolitica autoimmune (AIHA). Incontro nella terra dei Medici. Impiego clinico delle immunoglobuline endovena: presente e futuro. The high lysability by LAKs of colon carcinoma cells resistant to Doxorubicin is associated with a high expression of ICAM1, LFA3, NCA and a less-differentiated phenotype.(More)
The aim of the present study was to evaluate the effectiveness of two consecutive nonrandomised treatment programs applied between 1989 and 1999 at the Istituto Nazionale Tumori of Milan in an unselected cohort of 59 children over the age of one with stage 4 neuroblastoma. Both treatment programs consisted of two phases, the induction of the remission phase(More)
To reduce the sequelae from CNS irradiation (RT), 16 children younger than 3 years with medulloblastoma-PNET (13 cases) and ependymoma (3 cases) were treated between 1987-1993 according to different postsurgical chemotherapy (CT) programs. None of these patients presented with metastases. Eleven patients were rendered disease-free by surgery, while 5 had(More)
