The cytochemistry of acute leukemia: a diagnostic and prognostic evaluation.
A combination of cytomorphological features and cytochemical staining reactions in the diagnoses of the different types of acute leukemia removes much of the subjective difficulty of diagnosis. The number of cytochemical stains used may be limited, and in our experience the PAS, combined NCE and ANE reactions, and either SB or Px staining will yield as much diagnostic information as needed in most cases. With regard to the prognostic implications, it would appear at the present time that the amount of ANE staining in the cytoplasm of blasts is inversely proportional to the chances of remission induction and length of survival in cases of acute leukemia. However, further studies must be carried out to verify this finding before using the information to compliment other prognostic variables, such as age of patient, previous therapy, cytokinetics, etc.
