title: An analysis of prognostic factors in preleukemia: interest of bone marrow scintigraphy.
abstract: Simultaneous bone marrow scintigraphy with 99m Technetium colloids and 111 Indium transferrin was performed on 34 cases of preleukemic anemias and was shown to be of good prognostic value. Groups of different outcome were defined: for a normal and parallel uptake of the two markers, 90% of the patients died of acute leukemia; for a low Indium and high Technetium uptake, only 1 patient out of 15 died of leukemia (P less than 0.001). Standard clinical and hematological data were of no predictive value. Iron kinetic data and CFU/GM colony growth were correlated to the scintigraphic results. Taken together, these three kinetic parameters have a good sensitivity and specificity for the prognosis of preleukemic states.
