[Hematopoiesis in children with retroperitoneal neurogenic tumors]

Under observation were 140 children with retroperitoneal neurogenic tumors. In 69 of 125 patients with malignant neoplasms metastases were detected. Hemographic and myelographic findings were analysed depending on the degree of malignancy and tumor spread. Anemia usually moderate and normochromatic was observed only in neuroblastomas. This group of patients is also characterized by frequent shifts to the left leucograms and high sedimentation test, contrary to benigh tumors. The investigation of bone marrow allows one to reveal the suppression, and more rarely irritation of various blood stems.
