We analyzed the incidence of posttransplant chronic myelogenous leukemia (CML) relapse in 283 consecutive related-donor (n = 177) and unrelated-donor (n = 106) allogeneic transplant recipients. Twenty-two of 165 related-donor recipients with stable or advanced disease at the time of transplant had hematologic relapse of CML following transplant (5-year Kaplan-Meier estimate of relapse, 20%; 95% confidence interval [CI], 11 to 30%). One of 12 patients transplanted in second stable phase following blast crisis also relapsed. Fifteen related-donor transplant recipients relapsed within 5 years of transplant; however, seven relapsed between 5 and 9 years after transplant. Factors independently associated with an increased risk of posttransplant relapse for related-donor recipients included prolonged interval between diagnosis and transplant (relative risk, [RR], 3.81; P = .009) and bone marrow basophilia (RR, 5.62; P = .01). Related-donor recipients with posttransplant chronic graft-versus-host disease (CGVHD) had a decreased risk of relapse (RR, 0.24; P = .005). Only two of 106 unrelated-donor transplant recipients relapsed following transplant (5-year Kaplan-Meier estimate of relapse, 3%; 95% CI, 0% to 7%). When both related- and unrelated-donor recipients were considered, the use of an unrelated donor was independently associated with a decreased risk of relapse (RR, 0.24; P = .07). Twelve of 16 relapsing patients who received further therapy (nine of 13 who underwent second transplant and three of three who received donor leukocyte infusions) remain alive. This analysis shows that relapse, sometimes occurring long after transplant, is an important adverse outcome in allogeneic transplantation for CML. Early transplant, posttransplant CGVHD, and use of an unrelated donor are associated with a reduced incidence of relapse, perhaps due to allogeneic disparities enhancing the graft-versus-leukemia effect.

This study reviews results of a radiation-free preparative regimen consisting of busulfan and cyclophosphamide in 65 unrelated allogeneic bone marrow transplant recipients. Thirty-eight patients had chronic myelogenous leukemia (17 patients chronic phase, 13 patients accelerated phase, eight patients blast phase), 19 patients had acute leukemia (second complete remission or relapse) and eight patients had myelodysplasia. The patients were transplanted at four different medical centers from July 1988 to November 1992. Ages ranged 4-48 years (median 32). Fifty-seven patients received busulfan 16 mg/kg and cyclophosphamide 120 mg/kg, and eight received busulfan at doses between 15 and 17 mg/kg and cyclophosphamide at doses 100-200 mg/kg as preparative regimens. All patients received cyclosporine for graft-versus-host disease prophylaxis; in addition 46 patients received corticosteroid, 38 methotrexate, six anti-CD5 ricin A-immunotoxin, and four T cell-depleted bone marrow. Median follow-up of survivors was 53 months (range 15-68 months). Four year actuarial survival was 24 +/- 12%. Four-year survival based on disease was 29 +/- 27% for chronic myelogenous leukemia (CML) in chronic phase, 20 +/- 9% for chronic myelogenous leukemia in accelerated phase, 0% for chronic myelogenous leukemia in blast phase, 32 +/- 40% for acute leukemia, and 38 +/- 34% for myelodysplasia. Actuarial survival was 66 +/- 40% in patients age < 20 years, vs 23 +/- 13% for patients ages 20 to 40, and 10 +/- 14% for patients age > 40 years. Fifty patients (88%) engrafted. Graft failure occurred in eight patients. Acute graft-versus-host disease grade II-IV occurred in 36 (72%). Two patients relapsed after engraftment with the donor cells and died of leukemia within a month of relapse. The most common causes of death were graft-versus-host disease (37%), and transplant-related toxicity (59%); relapse (4%) was a rare cause of death. Busulfan/cyclophosphamide is an effective preparative regimen in unrelated bone marrow transplantation permitting adequate engraftment and a low relapse rate. Best results are observed in patients less than 20 years old.

Myeloablative treatment followed by lymphohaematopoietic reconstitution with stem cells from umbilical cord blood (UCB) can cure children with leukaemia. The clinical experience of UCB transplantation with HLA 2- and 3-antigen mismatched siblings is rather limited and there are no reports of such patient being given UCB significantly contaminated with maternal T lymphocytes. In this study, we report our experience in treating a child with chronic myeloid leukaemia in blast crisis who was transplanted using UCB cells from mismatched sibling donor containing a significant number of maternal T cells. The patient received 1.17 x 10(8) nucleated cells/kg after conditioning with Ara-C, busulphan, TBI and cyclophosphamide. GVHD prophylaxis was with cyclosporine and an anti-CD25 monoclonal antibody. Although engraftment was somewhat slow it was complete as documented by cytogenetic analysis and DNA studies. Results of minimal residual disease monitoring by RT-PCR for the hybrid BCR/ABL gene showed no evidence of leukaemic mRNA post-transplant. Acute GVHD, skin only, developed on day +14 but promptly responded to low-dose steroids. The technique used for UCB collection may have cell contamination found. In spite of these potential disadvantages: advanced disease, HLA antigen disparate donor and significant maternal T cell contamination, the transplant was successful and at a follow-up of 14 months the child is well with no evidence of chronic GVHD. Immune naivety of cord blood and lack of immunological reactivity of maternal T cells in this context may have played a significant role in the outcome of this case.

Results of 3000 patients transplanted for chronic myeloid leukemia in Europeere used to assess outcome and main risk factors for survival (SURV), leukemia free survival (LFS), relapse incidence (RI) and transplant related mortality (TRM). More than one third (39%) of all patients are alive at + 10 years. SURV at 10 years is better for patients transplanted in first chronic phase (49%) than in accelerated phase (19%) or blast crisis (0%) due to both decreased TRM (41% versus 67% versus -) and RI (35% versus 51% versus -). For those patients transplanted in first chronic phase from an HLA-identical sibling donor with non-T-cell depleted bone marrow, modern conditioning and GVHD prevention method, median SURV has not been reached at +10 years and exceeds 55%. Other risk factors are discussed.

From 1987 to 1991, 26 patients with CML and a median age of 31 years received allogeneic BMT from a partially mismatched related donor (PMRD) who shared at least one haplotype with the recipient. Nine patients were in accelerated phase (AP), and 11 patients were in blast crisis (BC) at the time of BMT. Patients were mismatched either in graft-versus-host or host-versus-graft directions for one antigen in 3 patients, two antigens in 14 patients, and three antigens in 9 patients. All patients were prepared with a regimen consisting of total body irradiation, etoposide, cytosine arabinoside, cyclophosphamide and methylprednisolone. All marrows were treated ex vivo with T10B91.A-31, a monoclonal antibody directed toward the alpha beta heterodimer of the CD3 receptor, and rabbit complement. Additional GVHD prophylaxis included either the anti-CD5 immunoconjugate XomaZyme-H65, cyclosporine, or both in combination with methylprednisolone. Eight patients did not have sustained engraftment. The 100-day survival was 42%. The incidence of > or = grade II acute GVHD was 29%. The incidence of chronic GVHD was 50% and was limited in all cases. The median survival at 4 years for all 26 patients was 27%. Seven patients (CP 1, AP 3, BC 3) remain in hematologic remission 1297-2241+ days after transplantation. AlloBMT from a PMRD may be considered for patients with advanced CML who lack a matched sibling or unrelated donor.

An increasing number of volunteer unrelated donor bone marrow transplantations (VUD-BMT) are performed every year for hematological malignancies due to the availability of a large donor pool. Here we show the results of 36 VUD transplants from our institution using a chemotherapy-only conditioning regimen comprising busulfan 4 x 4 mg/kg and cyclophosphamide 2 x 60 mg/kg. All patients received heparin 200 IU/kg bw continuous i.v. infusion starting the day before conditioning until day +30. Thirty-four of 36 patients (94%) engrafted and no secondary graft failure was observed. The two non-engraftments occurred in patients with CML in blast crisis with extensive myelofibrosis. All 34 engrafted patients (100%) were in complete remission on day +30 as shown by bone marrow biopsy and cytogenetic examinations. No life-threatening treatment-related morbidity or mortality (TRM) were observed, in particular, no severe veno-occlusive disease (VOD) of the liver and no fatal pulmonary complication. Use of G-CSF significantly shortened the time of neutropenia by 5 days. GVHD prophylaxis consisted of CsA/methylprednisolone with or without MTX. Acute GVHD grade II-IV was observed in 18/34 patients (53%) and cGVHD in 12/27 patients (45%), who survived to day +100. In seven patients (four with HLA class I or II mismatch) anti-T-lymphocyte globulin (ATG) was added for acute GVHD prophylaxis. One of seven had aGVHD grade II and none developed grade III to IV GVHD or graft failure. We conclude that Bu/CY is a feasible, save and sufficiently immunosuppressive regimen for VUD transplantation. Severe acute GVHD might be avoided by additional use of ATG in GVHD prophylaxis.

Thirty-two adults (median age 36 years) with leukemia (15 AML, eight CML, six ALL, three CLL) persisting or relapsing 1-40 months (median 4) after allogeneic BMT (20 matched siblings, eight unrelated, four family mismatch) underwent immunotherapy to elicit GVHD. This comprised one or more of: infusion of donor cells (n = 22), stopping cyclosporine (n = 14), and administration of interferon-alpha2b (n = 15) or interleukin-2 (n = 4). Eight acute leukemia patients received chemotherapy as well. The time from relapse to immunotherapy was 0-1344 days (median 4). Acute and/or chronic GVHD developed in 17 patients. Response was not evaluable in three patients due to early toxic death. There was no response in 10 patients, whereas 19 showed objective response. Nine patients died due to toxicity and 10 due to progressive disease. Thirteen patients are alive 4-58 months (median 14) after immunotherapy; 12 in remission (five AML, four chronic phase CML, one ALL, one accelerated phase CML, one CLL) and one with progressive disease (accelerated phase CML). Eleven of 13 patients who are alive had GVHD compared with six of 19 who died (P = 0.005, Fisher's exact test). We conclude that with the exception of CML in myeloid blast crisis, immunotherapy is active in most types of acute and chronic leukemia relapsing after allogeneic BMT. It is associated with considerable toxicity. Clinically obvious GVHD, especially chronic GVHD, results in a higher probability of survival.

We treated 12 patients with leukemia relapse after allogenic bone marrow transplantation with a combination of interferon-alpha (IFN-alpha) ((2.5-5.0) x 10(6) u/m2 subcutaneously three times a week) and interleukin-2 (IL-2) ((1.8-3.6) x 10(6) IU/m2 subcutaneously five times a week) to determine the toxicity and efficacy of combination cytokine therapy in this setting. The median age of the patients was 39 years (range: 16-50). There were nine females and three males. The median time to relapse from BMT was 98 days (range: 0-963). At the time of relapse, six patients had AML, four patients had CML (two in blast crisis and two in chronic phase with clonal evolution), and one patient had lymphoblastic lymphoma. Combination cytokine therapy was started a median of 108 days post BMT (range: 37-2404). Nine patients treated at the higher dose level required a 50% dose reduction because of toxicity or GVHD (three CNS, two GVHD, one high fever, one diarrhoea with hypotension, and one pericarditis). At a lower dose level, 2 of 10 patients had their treatment discontinued because of toxicity or GVHD. Six patients developed clinical findings consistent with acute GVHD while on combination cytokine therapy. Two patients responded to combination cytokine therapy: one with CML and one with AML. Combination cytokine therapy is feasible in the setting of relapse post allogeneic BMT. The combination of IL-2 1.8 x 10(6) IU/m2 five times a week with IFN-2 2.5 x 10(6) U/m2 three times a week seems to be tolerable, and merits further study in this setting.

Two patients with chronic myeloid leukemia (CML) who relapsed in blastic transformation after allogeneic bone marrow transplantation (BMT) were treated with infusions of leukapheresed peripheral blood mononuclear cells from their original donor. At relapse, their disease was characterized by symptomatic extramedullary deposits of leukemia with minimal (PCR positive, cytologically negative) involvement of bone marrow. Treatment with donor cell infusions was associated with clinical remission, return of full donor chimerism and loss of the BCR-ABL transcript detectable in bone marrow before donor leukocyte infusion (molecular remission). Donor leukocyte infusions should be considered for therapy of relapsed blastic phase CML after allogeneic BMT, especially when the relapse is primarily extramedullary and responsive to local and systemic cytoreductive therapy. However, severe GVHD and CNS relapse remain obstacles to achieving a successful long-term outcome.

Donor lymphocyte infusions (DLI) are an effective treatment of leukemia relapse after allogeneic bone marrow transplantation. Undesired side-effects are the development of graft-versus-host disease (GVHD) and the occurrence of pancytopenia in some patients. In a pilot study, we investigated if unmanipulated G-CSF-mobilized peripheral blood stem cells which naturally contain large numbers of T lymphocytes (D-PBSC/LI) would be equally effective or even superior than DLI in generating a graft-versus-leukemia reaction (GVL) but could mitigate or prevent the development of pancytopenia. We treated 12 patients with CML chronic phase (n = 5), CML blast crisis (n = 2), AML (n = 2), ALL (n = 1), CLL (n = 1) and multiple myeloma (n = 1). In five patients with acute leukemia or CML blast crisis D-PBSC/LI followed intensive chemotherapy (group A), in seven patients D-PBSC/LI were given without any prior chemotherapy (group B). In group A two patients were evaluable for hematologic toxicity. Leukopenia <1000/microl lasted for 10 and 19 days, and thrombocytopenia <20,000/microl for 11 and 13 days, respectively. In group B leukopenia <1000/microl and thrombocytopenia <20,000/microl was observed in only one patient. Moderate cytopenia developed in four of five evaluable patients. A complete remission could be achieved in all seven patients with CML who all developed acute and/or chronic GVHD. None of the remaining five patients achieved a complete remission despite acute and/or chronic GVHD in two of them. Four patients died from disease progression, one patient from a secondary lymphoma, and one patient as a result of uncontrolled GVHD. In conclusion, D-PBSC/LI is effective in inducing GVL reaction but it does not prevent pancytopenia in each case. It remains unclear if it mitigates the incidence and severity of pancytopenia.
