[SCE rate and lymphocyte differentiation in children with acute lymphoblastic leukemia and SCE rates of leukemia patients in long-term remission].

Sister chromatid exchanges (SCE) and lymphocyte subsets of children with acute lymphoblastic leukemia (ALL) were investigated in children with ALL during chemotherapy and at least 5 years after chemotherapy. The treatment of the new admitted patients followed protocol ALL-BFM-90. Children with ALL at the time of diagnosis showed statistically significant higher SCE frequencies (4.
