    Notes: Abstract Seventy-eight transfusions of autologous platelets were given to eight alloimmunized patients receiving curative chemotherapy for acute leukemia. Platelets were collected at regeneration of hematopoiesis after a chemotherapy cycle, cryopreserved with 5% dimethylsulfoxide in liquid nitrogen, and retransfused during bone marrow aplasia following the next treatment cycle. The in vitro platelet recovery after freezing, thawing, and washing was 85 ±4%. The in vivo corrected count increment 1 h after autologous platelet transfusions was 11±5×109/l. With the exception of moderate urticaria and slight nausea each after one transfusion, no immediate or chronic side effects occurred. The bleeding time was shortened and hemorrhage during bone marrow aplasia was prevented in all alloimmunized patients by autologous platelet transfusions.

    Description / Table of Contents: Zusammenfassung In einer prospektiven, multizentrischen Studie wurde der Verlauf bei 33 Patienten mit Präleukämie verfolgt. Kriterien für die Aufnahme in die Studie waren eine Anämie mit Granulo- und/oder Thrombozytopenie bei normal oder erhöht zellreichem Knochenmark und Ausschluß einer für diese Veränderungen verantwortlichen Grunderkrankung oder externen Noxe. Die kürzeste Nachbeobachtungszeit nach Stellung der Diagnose „Präleukämie“ betrug 3 Jahre. Die mediane Überlebenszeit war 26 Monate nach Ersterfassung und 36 Monate nach Erstsymptom der Erkrankung. Remissionen wurden nicht beobachtet. Bei 40% der Patienten wurde innerhalb von 2 Jahren nach Ersterfassung eine akute Leukämie diagnostiziert. Unter den geprüften prognostischen Faktoren sprachen vor allem Chromosomenaberrationen und ein erhöhter Blastenanteil für den Übergang in eine akute Leukämie.
    Notes: Summary The natural course of disease was followed in 33 patients with so-called preleukemia by a prospective multicentric protocol. Patients with the following criteria were included: Anaemia with granulocytopenia and/or thrombocytopenia, normal or increased cellularity of the bone marrow and exclusion of a known diagnosis of underlying disease. Follow up after assumption of “preleukemia” was 3 years or more. Median survival was 26 months after diagnosis of preleukemia and 36 months after the first unequivocal symptoms of the blood dyscrasia. 40% of the patients changed to the picture of leukemia within 2 years. The most important parameters suggesting subsequent transition to overt leukemia where chromosomal abberations and an increased blast count of the bone marrow.
