From September 1988 to September 1987, the author of 17 cases of children with retroperitoneal malignancy in children (neoplastic embryonic neoplasia in 13 cases, 4 cases of neuroblastoma; the youngest 3 months, maximum 6 years old, mean age 2 years old) Determination of zinc, copper and iron in serum, hair and tumor tissues. Results: The contents of serum, tumor tissue and hair elements in renal embryonal and neuroblastoma patients had the same pattern. The zinc content was hair> tumor tissue> serum, copper and iron content was tumor tissue> hair> serum, copper The ratio of zinc to serum is serum > tumor tissue. This shows that in this group of children serum
