title: [Tumor lysis syndrome in the course of neoplastic disease of hematopoietic system in children].
abstract: Tumor lysis syndrome is characterized by hyperuricemia, hyperkalemia and hyperphosphatemia followed by hypocalcemia. Sometimes they are accompanied by hyperglycemia. It can lead to acute renal insufficiency, neurological and cardiological disorders. In the Clinic of Paediatric Haematology and Chemotherapy in Zabrze, in the period from Jan.01, 1990 to Dec.31, 1997, 305 children were treated due to neoplastic diseases of haematopoietic system: 169 with ALL, 34--ANLL, 48--NHL and 54--HD. Tumor lysis syndrome was found in 11 children, what was 3.6% of all patients. They included 3 children with ALL/1 from group SRG and 2 with HRG/, 2 with ANLL, 6 with NHL/2 with NB-NHL and 4 with B-NHL/. Tumor lysis syndrome did not occur in any patient with HD. Two symptoms of tumor lysis syndrome were found in 13 children (4.26%) including 3 with ALL (1 SRG and 2 HRG), 2 with ANLL and 8 NHL/3-NB-NHL and 5-B-NHL/. Diabetes occurred in two children with ALL. Acute renal insufficiency occurred in 6 children with ALL, 2 with ANLL and 8 with NHL. Two patients with B-NHL required dialysis. One renal insufficiency treated with hemodialyses was the first symptom of lymphoma. To prevent the consequences of tumor lysis syndrome hydration with alkalization, constant monitoring of the above mentioned biochemical parameters are necessary. Acute renal insufficiency, not responding to conservative treatment, should be immediately treated with hemodialyses and chemotherapy should be introduced under its 'shield'.
