Eighteen patients with relapse of chronic myelogenous leukemia (CML) after allogeneic bone marrow transplantation (BMT) were treated with recombinant human alpha 2a interferon (IFN). Relapse was defined as greater than 90% metaphases containing the Philadelphia chromosome (Ph) and hematologic abnormalities consistent with chronic-phase (CP) CML. There were 11 males and seven females, with a median age of 38 years (range, 3 to 55). Three patients relapsed after second BMT. Only one patient had received T-cell-depleted marrow initially. The initial IFN dose of 3 x 10(6) U/m2/d was escalated to the maximum tolerated dose or to a maximum of 6 x 10(6) U/m2/d. IFN controlled the white blood cell (WBC) counts in 14 of 16 patients who had abnormal counts, and in all six patients with an elevated platelet count. Six patients (33%) have had a complete disappearance of the Ph and two have had a partial response (less than 35% Ph+ metaphases). One patient has a decrease in Ph+ metaphases after 9 months of IFN. Five patients had no significant cytogenetic response after 9 to 12 months, and four developed clinical accelerated phase or blast crisis after 3 to 6 months on therapy. Of four patients with a sex marker, the Ph- population was of donor origin in three and of host origin in one. Clonal cytogenetic abnormalities other than Ph were present in 13 patients and did not predict for lack of response to IFN. IFN is effective in suppressing the Ph clone in some patients who relapse with CML after allogeneic BMT and controls the blood counts in the majority.

Abstract The influence of interferon- (IFN) pretreatment on the outcome after allogeneic bone marrow transplantation (BMT) in chronic myelogenous leukemia (CML) is controversial. One goal of the German randomized CML Studies I and II, which compare IFN ± chemotherapy versus chemotherapy alone, was the analysis of whether treatment with IFN as compared to chemotherapy had an influence on the outcome after BMT. One hundred ninety-seven (23%) of 856 Ph/bcr-abl–positive CML patients were transplanted. One hundred fifty-two patients transplanted in first chronic phase were analyzed: 86 had received IFN, 46 hydroxyurea, and 20 busulfan. Forty-eight patients (32%) had received transplants from unrelated donors. Median observation time after BMT was 4.7 (0.7 to 13.5) years. IFN and chemotherapy cohorts were compared with regard to transplantation risks, duration of treatments, interval from discontinuation of pretransplant treatment to BMT, conditioning therapy, graft-versus-host disease prophylaxis and risk profiles at diagnosis and transplantation, and IFN cohorts also with regard to performance and resistance to IFN. Outcome of patients receiving related or unrelated transplants pretreated with IFN, hydroxyurea, or busulfan was not significantly different. Five-year survival after transplantation was 58% for all patients (57% for IFN, 60% for hydroxyurea and busulfan patients). The outcome within the IFN group was not different by duration of prior IFN therapy more or less than 5 months, 1 year, or 2 years. In contrast, a different impact was observed in IFN-pretreated patients depending on the time of discontinuation of IFN before transplantation. Five-year survival was 46% for the 50 patients who received IFN within the last 90 days before BMT and 71% for the 36 patients who did not (P = .0057). Total IFN dosage had no impact on survival after BMT. We conclude that outcome after BMT is not compromised by pretreatment with IFN if it is discontinued at least 3 months before transplantation. Clear candidates for early transplantation should not be pretreated with IFN.

PURPOSE Allogeneic bone marrow transplantation (BMT) is an option for some patients with chronic myelogenous leukemia (CML). We retrospectively evaluated the effect of various risk factors observed at diagnosis and at transplantation on survival, event-free survival (EFS), and relapse after BMT. PATIENTS AND METHODS Seventy-nine patients with CML in chronic phase (CP) were treated with cyclophosphamide and total body irradiation followed by BMT. Graft-versus-host disease (GVHD) prophylaxis consisted of cyclosporine (CsA) in most instances or CsA plus the use of lymphocyte-depleted bone marrow (BM). RESULTS Survival at 4.5 years was 52%. Stratified by age and GVHD prophylaxis, the actuarial survival was 65% (95% confidence interval [CI], 47% to 78%) in patients aged less than 30 years receiving unmanipulated BM, 33% (95% CI, 12% to 56%) in patients greater than or equal to 30 years old receiving unmanipulated BM, and 38% (95% CI, 14% to 63%) in patients greater than or equal to 30 years old receiving lymphocyte-depleted BM. In univariate analysis, patient age (greater than or equal to 30 years) and the use of lymphocyte-depleted BM negatively influenced EFS. When stratified by age and GVHD prophylaxis, however, ABO incompatibility, cytomegalovirus (CMV) seropositivity, and chronic GVHD significantly reduced the probability of EFS. Factors that have been associated with early death in nontransplanted patients (ie, sex, spleen size, blast and platelet counts at presentation) were not predictive of long-term survival outcome after BMT. CONCLUSIONS The data suggest that (1) BMT should be offered early after diagnosis to all patients with CML in CP who have compatible sibling donors regardless of prognostic factors at presentation, (2) GVHD remains the principal cause of mortality after BMT in patients receiving CsA, and (3) T-cell depletion by the physical separation method of counterflow elutriation (CE) is associated with a significant risk of relapse.
