[Correlation of the cytochemical classification of acute leukemia in children with the course of their disease (author's transl)]. / Zur Korrelation der zytochemischen Klassifizierung akuter kindlicher Leukämien mit deren klinischem Verlauf.

Acute leukemia in 93 children was cytochemically classified into three groups: 1. the PAS-Typ (acute undifferenciated leukemia) paramyeloblastic leukemia, 2. the AML, and 3. the Acid Phosphatase Typ (SP-Typ). Therapy for the first group differed from that for AML. The acid-Phosphatase-Typ was found in only a few cases, where the acid Phosphatase is good to see in the paranuclear region of the cell. These cases have a bad prognosis. It is proposed to publish even single cases of the acid Phosphatasetype leukemia in order to find the optimal therapy.
