Intracellular concentrations of 6-mercaptopurine metabolites, i.e. of 6-thioguanine nucleotides (6-TGN) and of 6-methylmercaptopurine metabolites (6-mMP) were analysed in red blood cells (RBC) of 19 children with acute lymphoblastic leukemia (ALL), the subjects of a maintenance chemotherapy of their first remission. Interpatient variations in concentrations of both metabolites were high; concentrations of 6-TGN varied from <60 to 833 pmol/8x10(8) RBC (median value, 144) and those of 6-mMP metabolites from <150 to 19000 pmol/8x10(8) RBC (median value, 3250). In two patients, 6-TGN appeared at concentrations below the limits of assay sensitivity, and 6-mMP metabolites were not detected. In another child the concentrations of both metabolites were at the limit of the assay sensitivity. In three other children the concentrations of both metabolites were below the median value of the group. In the analysed group of children, significant correlations were found between the white cell count (WBC) and RBC 6-TGN (r(s)=-0.72, P<0. 005) as well as between the neutrophil count and RBC 6-TGN (r(s)=-0.60, P<0.01). No significant correlation was found between the concentrations of 6-TGN and 6-mMP metabolites. The monitoring of concentrations of 6-TGN as well as of 6-mMP metabolites allows an early identification of patients who are at an increased risk of the disease relapse as indicated by the low levels of either 6-TGN itself or of its two metabolites.
