neuroectodermal tumors primitive/アルブミン

Despite the phenotypic similarities between primitive neuroectodermal tumors of the central nervous system, childhood neuroblastoma, and peripheral neuroepithelioma, a histogenetic relationship among these neoplasms has not been shown. High levels of N-myc expression occur selectively in developing

The 3-5 year survival rates of patients with disseminated Ewing's sarcoma (ES) or the closely related peripheral primitive neuroectodermal tumors (PNET) remain low, even under aggressive treatment involving highly toxic multidrug chemotherapeutic regimens. ES and PNET are sensitive to doxorubicin,

Intra-arterially injected macroaggregates of radioiodinated human serum albumin were used in the detection of brain tumours in mice and in human subjects. The mean size of particle used was 29 mu. Brain-to-tumour ratios in ependymoblastoma-bearing mice ranged from 43.5:1 to 2.8:1. Autoradiographs of

The records of 116 patients from a single center (1970-1993) with newly diagnosed Ewing's sarcoma or primitive neuroectodermal tumor were reviewed retrospectively. The aim of this study was to ascertain the impact of pretreatment variables on disease-free survival. Median age was 14 years (range

We describe a 4-yr-old boy with an occult primitive neuroectodermal tumor, who suffered fatal PTE after a second course of HDC with autologous PBSCT. On day + 52 after a second PBSCT, he was admitted because of respiratory distress. Respiratory failure rapidly progressed and he died within 4 days.
