Clinicopathological considerations on angiogenic potential in neuroblastoma Schwannian stroma - poor tumours.

The aim of the study was to determine microscopic angiogenic parameters of neuroblastoma (NB) Schwannian stroma-poor tumours. Furthermore the associations between vascular parameters and clinicopathological features of tumours and basic prognostic factors were analysed. Examined tissue samples from 62 NB came from 39 untreated and 23 chemotherapy pretreated tumours.

Unlabelled: We present the results of treatment of kidney tumours in newborns and infants aged less than 6 months, in the years 1993-2000, from the Nephroblastoma Committee of the Polish Paediatric Group of Solid Tumours (PPGGL). We have analysed the diagnostic and treatment results in the group of 31 children aged 0 to 6 months. For 19 children registered between 1993 and 1996, event-free survival (EFS) and overall survival (AS) were assessed.
