[Prognostic factors in neuroblastoma in children].

The results of clinico-morphological studies of 152 cases of neuroblastoma are presented. Neuroblastoma should be regarded as a tumor in which the following patterns may be distinguished: sympatogonioma (2.6%), sympatoblastoma -1 (38.8%), sympatoblastoma -2 (15.2%), ganglioneuroblastomia (41.4%), and combined ganglioneuroblastoma (2%). Mean two-year survival rate was 40.2%. Such factors as patient's by the time of tumor detection, radical surgery and excision of primary neoplasm in patients with metastases were found to improve the prognosis. The two-year survival rates in sympatoblastoma -1, sympatoblastoma -2 and ganglioneuroblastoma were 19.6, 50, and 72%, respectively.
