Summary Between 1983 and 1991 the Philadelphia chromosome (Ph1) was found in bone marrow and/or peripheral blood cells of 25 adult patients with acute lymphoblastic leukemia (ALL). The Ph1 as sole anomaly was seen in 13 patients, while six patients had additional structural and another six structural and numerical aberrations. Most patients (23/25) received combination chemotherapy according to the BMFT protocols 1/81, 2/84, 3/87, and 4/89. For 25 evaluable patients two early deaths, two treatment failures, two partial remissions (PR), and 19 complete remissions (CR) after phase 1 or 2 of the induction regimen were recorded. Two of these 19 patients who achieved CR are presently disease free, whereas 17 have relapsed after a median duration of remission of 9 months. Actuarial median survival for all patients was 13 months. The probability of continuous complete remission (CCR) after 39 months, as well as that of survival after 40 months, is only 6%. Our results confirm that the presence of the Ph1 is associated with a poor prognosis in adult-ALL patients. Therefore, whenever first CR is obtained and an HLA-identical donor is available, allogeneic bone marrow transplantation (BMT) should be performed at once, the more so, since transplantation in second CR seems to offer no cure. Future studies will have to show whether an intensified cytotoxic therapy can improve the prognosis of Ph1+-ALL.
