Sixteen patients with relapse after allogeneic BMT were treated with donor leukocyte infusions (DLI) from the original donor. The diagnoses at relapse were: CML in chronic phase (CP) (two patients), CML in accelerated phase (AP) (four patients), AML (four patients), MDS (one patient), ALL (four patients) and relapse of Hodgkin's disease (one patient). The patients received a mean of 5.2 x 10(8) leukocytes/kg with a range of 1.4-12.3 x 10(8) leukocytes/kg. Six patients obtained complete remission (CR), one with CML in CP, three with CML in AP, one MDS and one ALL. Partial remission (PR) was seen in three patients, one patient with CML in AP, one with AML and one with Hodgkin's disease. Seven patients had no response (NR) to the infusions, including one patient with CML in CP transplanted with a syngeneic donor. Four patients developed marrow hypoplasia after DLI (three CR and one PR) and two patients (ALL with CR and MDS with CR) were hypoplastic at relapse and marrow hypoplasia continued after DLI. GVHD occurred without GVL, but GVL only occurred in one patient with absence of GVHD. Eleven patients died of leukemia, six patients are alive. Three patients with CML are in CR 12, 12 and 32 months after DLI and one patient with ALL is in CR 15 months after DLI.  相似文献

Two cases of acute myeloid leukemia (AML) presenting with bulky adenopathy are reported. Both patients were febrile at admission and showed massive and diffuse lymph node involvement, hepatomegaly, and splenomegaly. Erythematopapular leukemic skin lesions were present in one case at the onset and developed in the other at the time of relapse. Anemia, thrombocytopenia, and moderate leukocytosis were present in both. The presence of immature cells in peripheral blood and bone marrow allowed a rapid diagnosis of AML, FAB M1, in one patient. In the other case, owing to the paucity of immature cells in peripheral blood and bone marrow, lymph node biopsy with histology, imprint cytology, and immunocytochemistry were essential for the diagnosis (AML, FAB M2, with trilineage dysplasia and basophilic involvement). Both patients achieved complete remission (CR), followed by an early relapse 3 months later. They underwent allogeneic bone marrow transplantation (BMT) from HLA identical siblings. One patient is actually alive and in CR at 6 months after BMT; the other patient showed a leukemic regrowth after transplantation and died 4 months later.  相似文献

Thirty-eight second allogeneic bone marrow transplants (BMT) for acute leukemia relapsed after first BMT were performed in 13 Italian centers between 1987 and 1994. Twenty-one patients had acute myelogenous leukemia (AML), 17 acute lymphoblastic leukemia (ALL); at second BMT 24 patients were in complete remission (CR) and 14 in relapse. The median time to relapse after first BMT was 10 months (range 1-70). Grade II or greater acute graft-versus-host disease (GVHD) after second transplant occurred in 34.2% of patients and a chronic GVHD in 31.5% of patients. Twenty-four patients died: seven from early transplant-related mortality (TRM), 13 from relapse and four from late toxicity. As of 31 July 1996, at a median follow-up of 47 months (range 22-85), there are 14 survivors. The three-year probability of TRM, relapse and event-free survival (EFS) is 28%, 40% and 42% respectively. In 20 of 27 evaluable patients, remission duration after second BMT was longer than after the first BMT. A diagnosis of AML was correlated with a better outcome. These data support the usefulness of second allograft in selected patients with AML relapsing after a first BMT.  相似文献

PURPOSE: To evaluate in a prospective study the efficacy of autologous bone marrow transplantation (BMT) in adult patients with acute myelogenous leukemia (AML) in first remission, using a single course of high-dose Cytarabine (HD Ara-C) consolidation therapy as in vivo purging. PATIENTS AND METHODS: Sixty consecutive adult patients with AML in first complete remission (CR) were treated with HD Ara-C consolidation therapy as a method of in vivo purging before marrow collection. High-dose therapy consisted of fractionated total-body irradiation (FTBI) 12 Gy, intravenous etoposide 60 mg/kg, and cyclophosphamide 75 mg/kg, followed by reinfusion of cryopreserved marrow. RESULTS: Sixty patients underwent consolidation treatment with HD Ara-C with the intent to treat with autologous BMT. Sixteen patients were unable to proceed to autologous BMT (10 patients relapsed, one died of sepsis, one developed cerebellar toxicity, two had inadequate blood counts, and two refused). Forty-four patients underwent autologous BMT and have a median follow-up time of 37 months (range, 14.7 to 68.7) for patients who are alive with no relapse. The cumulative probability of disease-free survival (DFS) at 24 months in the intent-to-treat group is 49% (95% confidence interval [CI], 37% to 62%) and in those who actually underwent autologous BMT is 61% (95% CI, 46% to 74%). The probability of relapse was 44% (95% CI, 31% to 58%) and 33% (95% CI, 20% to 49%) for the intent-to-treat and autologous BMT patients, respectively. CONCLUSION: This approach offers a relatively high DFS rate to adult patients with AML in first CR. The results of this study are similar to those achieved with allogeneic BMT.  相似文献

We report here that a patient with relapsed AML after allogeneic bone marrow transplantation achieved and maintained complete remission (CR) after effective donor leukocyte transfusion (DLT), without the occurrence of GVHD and marrow aplasia, for more than 21 months. This continuous CR maintenance is mainly due to the application of DLT at molecular relapse that was diagnosed by monitoring minimal residual disease (MRD) by the quantitation of WT1 (Wilms tumor gene) expression levels (WT1 assay). The present case demonstrates that early application of DLT at molecular relapse is essential for the improvement of the efficacy of DLT for relapsed AML after BMT.  相似文献

Treatment options for acute leukemia relapsing after allogeneic BMT include conventional chemotherapy or a second transplant; however, results are rather discouraging, the first option being associated with poor survival and the second with a high mortality rate. More recently, donor leukocyte infusion (DLI) from the original donor has been used for relapsed patients in an attempt to induce a graft-versus-leukemia (GVL) effect. This procedure is partially devoid of the toxicity inherent to a second BMT. At our Institution, a 36-year-old patient with biphenotypic AML in second complete remission after relapse following allogeneic BMT was treated with peripheral blood stem cell (PBSC)-enriched donor leukocytes, obtained after in vivo priming with rhG-CSF. The patient experienced extensive cGVHD but developed a testicular relapse while in full hematologic remission. After irradiation of the sanctuary site he remains free of disease, still with chronic GVHD, 21 months after bone marrow relapse. This case suggests that immunologically privileged sites are inaccessible to GVHD/GVL effect. This should be considered when planning salvage transplants procedures in patients at risk for extramedullary involvement.  相似文献

Relapse remains a significant problem after allogeneic bone marrow transplantation (BMT). For patients with relapsed chronic myelogenous leukemia (CML), infusions of donor mononuclear cells (MNC) provide a potent graft-versus-leukemia (GVL) reaction inducing complete remissions in the majority of patients. Little is known about the efficacy of donor MNC infusions for patients who relapse with other diseases. We have studied the GVL effects of donor MNC in eight patients with relapsed acute leukemia or myelodysplasia (MDS). One patient with relapsed MDS achieved complete remission and another patient had a transient response. Five of six non-responders died of progressive leukemia and one non-responder died of complications during second BMT. Three patients developed grade I-II acute GVHD responsive to immunosuppression. These data, and review of the literature, suggest that GVL induction with donor MNC infusions is less effective for patients with relapsed acute leukemia than for patients with relapsed CML; too few patients with relapsed MDS have been treated to draw definite conclusions. However, some patients respond, and given the high mortality associated with alternative procedures such as second BMT, donor MNC infusions are a reasonable approach for relapsed acute leukemia and MDS after allogeneic BMT.  相似文献

We analyzed results of 40 infants less than 2 years of age who received bone marrow transplants (BMT) between May 1974 and January 1995 for treatment of acute myelogenous leukemia (AML; N = 34) or myelodysplastic syndrome (MDS; N = 6) to determine outcome and survival performance. Among the AML patients, 13 were in first remission, 9 were in untreated first relapse or second remission, and 12 were in refractory relapse. Patients were conditioned with cyclophosphamide in combination with either total body irradiation (TBI; N = 29) or busulfan (N = 11). Source of stem cells included 6 autologous donors, 15 HLA genotypically identical siblings, 14 haploidentical family members, and 5 unrelated donors. Graft-versus-host disease (GVHD) prophylaxis was methotrexate (MTX) for 17, MTX plus cyclosporine (CSP) for 14, or CSP plus prednisone for 3. Incidence of severe (grade 3-4) regimen-related toxicity was 10% and transplant-related mortality was 10%. Acute GVHD (grades II-III) occurred in 39% of allogeneic patients, and chronic GVHD developed in 40%. Relapse, the most significant problem for patients in this study, occurred in 1 MDS patient and 23 AML patients and was the cause of death for 19 patients. The 2-year probabilities of relapse are 46%, 67%, and 92%, respectively, for patients transplanted in first remission, untreated first relapse or second remission, and relapse. One MDS and 8 AML patients received second marrow transplants for treatment of relapse, and 5 of these survive disease-free for more than 1.5 years. All 6 MDS patients and 11 of 34 AML patients survive more than 1.5 years later. The 5-year probabilities of survival and disease-free survival are 54% and 38% for patients transplanted in first remission and 33% and 22% for untreated first relapse or second remission. None of the patients transplanted with refractory relapse survive disease-free. Outcome was significantly associated with phase of disease at transplantation and pretransplant diagnosis of extramedullary disease. Long-term sequelae included growth failure and hormonal deficiencies. Survival performance was a median of 100% (80% to 100%) and neurologic development for all survivors was appropriate for age. This study indicates that infants with AML have similar outcome after BMT compared with older children and that BMT should be performed in first remission whenever possible. In addition, allogeneic BMT provides effective therapy for the majority of infants with MDS.  相似文献

The recovery of colony-forming cell numbers after curative treatment for leukemia and severe aplastic anemia (SAA) was studied. We examined 191 patients (85 acute myeloid leukemia [AML], 48 acute lymphocytic leukemia [ALL], 32 chronic myeloid leukemia [CML], 17 SAA, and nine myelodysplastic syndrome [MDS]) who were in hematologic remission 6 months to 13 years after either curative chemotherapy (n = 69) or allogeneic bone marrow transplantation (BMT) (n = 122) by culturing their precursor cells from bone marrow (BM) (n = 548) and peripheral blood (PB) (n = 529) in methylcellulose. Thirty-six BM donors and 25 PB donors served as controls. BM colony-forming cell numbers were abnormally low in all patients (p < 0.002) irrespective of underlying disorder and type of treatment (chemotherapy or irradiation). These numbers did not normalize with time--colony-forming cells were still strongly reduced up to 10 years after therapy, whether or not the patient had received an allogeneic bone marrow graft (p < 0.002). We also compared patients who remained in stable hematologic remission with those who later relapsed (6 months to 2 years after treatment). BM colony-forming cell numbers were significantly lower in patients who subsequently relapsed (p = 0.004). In contrast to BM cultures, we found normal colony-forming capacity by PB precursors in all patients. We conclude that (1) after chemotherapy or BMT, colony-forming cell numbers of BM in culture are permanently reduced; (2) this defect is probably due to a dysfunction of the BM environment rather than to a numerical reduction of the precursor cell pool; and (3) very low colony-forming capacity may be related to relapse.  相似文献

Allogeneic bone marrow transplantation (BMT) is the only effective treatment for hematologic malignancies resistant to conventional chemotherapy. Until recently, no cure existed for patients who relapsed post-BMT. We present our long-term observations on remission induction, after relapse post-BMT, by allogeneic cell therapy (allo-CT) and the feasibility of remission induction in allo-CT-resistant patients by activation of antileukemia effector cells with recombinant human interleukin-2 (rhIL-2) in vitro and in vivo. The longest observation of successful allo-CT (event-free survival, greater than 8 years) was made in a patient with resistant pre-B lymphoblastic leukemia who received infusions with graded increments of donor (female) peripheral blood lymphocytes (PBL) as soon as bulky hematologic and extramedullary relapse was noticed early post-BMT. The patient is currently without evidence of residual host (male) cells as determined by polymerase chain reaction (PCR). Of 17 patients with acute and chronic leukemia in relapse after BMT, 10 were reinduced into complete remission. Four patients with cytogenetic relapse responded to allo-CT alone, while five of six patients with overt hematologic relapse responded only after additional activation of donor with rhIL-2. Allo-CT can, therefore, successfully reverse chemoradiotherapy-resistant relapse of both acute and chronic leukemia. Moreover, in patients resistant to donor lymphocyte infusion, remission can be accomplished by additionally activating donor PBL in vitro and/or in vivo with rhIL-2. Based on our observations, after BMT, allo-CT should be considered the treatment of choice for patients with hematologic malignancies resistant to conventional anticancer modalities. Allogeneic activated cell therapy (allo ACT) should be considered for patients with tumor cells resistant to allo-CT. Although allo-CT, followed if indicated by allo-ACT, can be effective for patients with overt hematologic relapse, reversal of persistent minimal residual disease or documented molecular/cytogenetic relapse early after BMT may also be considered as a possible indication for allo-CT.  相似文献

Determination of hematological chimerism could be helpful in understanding the biology of leukemic relapse after allogeneic bone marrow transplant (BMT) for chronic myeloid leukemia (CML), because the detection of malignant residual cells carrying the bcr/abl message by qualitative RT-PCR is of limited value in predicting disease progression for individual patients. We have studied the chimerism pattern and the bcr/abl status by Southern-blot in 15 CML patients (M/F:6/9) transplanted with unmanipulated BM from HLA identical sibling donors, persistently bcr/abl positive by RT-PCR. The median age of the series was 31 years (18-49) and disease status at BMT was: chronic phase: 11, accelerated phase: 3 and blast crisis: 1 patient. Of the 15 patients, 9 are alive and in complete remission (CR), 4 have died in CR and 2 are alive but suffered relapse at + 19 and +26 months post-BMT. The median follow-up is 81 months (13,7-168). Rearrangement of the BCR gene was performed by Southern-blot using P32-labeled transprobe-1. PCR analysis of chimerism was assessed using primers for the following VNTR loci: D1S80, D1S111, 33.1, APO-B, YNZ-22, lambdag3 and DXS52. Seventy-nine samples were analyzed (median per patient 5 (range 2-9)). Thirteen patients showed complete chimerism and lacked BCR rearrangement over time by Southern-blot. The 2 patients who relapsed showed mixed chimera status from +9 and +5 months respectively until the end of the study. Persistent BCR rearrangement was observed in these 2 patients from +12 and +11 months respectively. Our data suggest that mixed chimerism may predict hematologic or cytogenetic relapse by several months in those patients who are persistently PCR-positive post-BMT.  相似文献

Myeloablative therapy followed by allogeneic bone marrow transplantation (BMT) has proven to be curative therapy in patients with hematologic malignancies. Relapse, however, remains a major cause of treatment failure for patients with advanced disease. During the past 15 years, we have gained considerable experience with the combination of fractionated total-body irradiation (FTBI) and etoposide followed by allogeneic BMT for hematologic malignancies. In an attempt to decrease post-transplant relapse rates, 67 patients under the age of 50 years with high-risk or advanced-stage hematological malignancies received an intensified regimen of FTBI and etoposide plus cyclophosphamide followed by BMT from a genotypically-matched related donor. The regimen consisted of 1320 cGy of FTBI in 11 fractions, 60 mg/kg of etoposide (VP-16), and 60 mg/kg of cyclophosphamide (CY). Fifty-three patients received cyclosporine and prednisone for graft-vs.-host disease (GVHD) prophylaxis and 14 patients received cyclosporine, methotrexate, and prednisone. Diagnosis at BMT included 45 patients with acute leukemia, 7 patients with chronic leukemia, and 15 patients with high-grade non-Hodgkin's lymphoma (NHL). Actuarial disease-free survival (DFS) at 3 years was 42% +/- 12% for the entire group with a median follow-up of 50 months (range 20-74) for 28 patients who remain alive in continued complete remission (CR). Actuarial 3-year-DFS was 38% +/- 14% in 52 patients with acute or chronic leukemia and 60% +/- 25% in 15 patients with NHL with relapse rates of 45% +/- 16% and 21% +/- 11%, respectively. DFS at 3 years was 40% +/- 18% in 32 patients with acute leukemia in 1st relapse or 2nd CR or chronic myelogenous leukemia in accelerated phase, and was 32% +/- 22% in 20 patients with more advanced disease. Regimen related mortality occurred in 9 patients (4, veno-occlusive disease of the liver; 2, multi-organ failure; 1, diffuse alveolar hemorrhage; 1, central nervous system (CNS) hemorrhage; 1, adult respiratory distress syndrome (ARDS). The combination of FTBI, etoposide, and cyclophosphamide followed by allogeneic BMT is an effective and relatively well-tolerated regimen for patients with advanced hematologic malignancies. The role for this regimen should be further defined by prospective clinical trials.  相似文献

We report an unusual case of a patient who was cured of one autoimmune disease (palmoplantar pustular psoriasis (PPP)) but developed another autoimmune disease (autoimmune thyroiditis) after allogeneic BMT. A 40-year-old man suffering from AML with PPP underwent allogeneic BMT from his HLA-identical sister for the treatment of AML. The patient experienced complete clearance of the cutaneous PPP despite the cessation of immunosuppressive therapy for over 2 years. However, he developed hyperthyroidism with anti-thyroglobulin antibodies 5 months after BMT, although he had showed normal thyroid functions without anti-thyroglobulin antibodies before BMT. The donor had no history of thyroid diseases and showed normal thyroid functions but was positive for anti-thyroglobulin antibodies. Thus, even when the donor is in a subclinical state, autoimmune thyroiditis may be transferred from donors to recipients by BMT.  相似文献

There is increasing interest in blood cell transplants (BCT) from normal donors as an alternative to BMT. Ten patients with relapsed or persistent leukemia after BMT received intensive cytotoxic conditioning followed by allogeneic BCT. Three BCT were from single-antigen mismatched donors; two of the corresponding recipients had rejected a BMT from the same donor. Two patients received BCT from a different donor (one matched, one single-antigen mismatched). The other six BCT were from the same, fully matched, bone marrow donors. Donors were given G-CSF to mobilize progenitor cells which were collected by a single 2-4 h leukapheresis. Methotrexate, CsA and folinic acid were used for GVHD prophylaxis for all transplants but CsA was discontinued sooner after BCT than after BMT. One patient died without engraftment having rejected a BMT from the same single-antigen mismatched donor 4 years previously. Nine patients had granulocyte recovery at a median of 14 days, up to 6 days faster than with their previous BMT. Platelet recovery was also 2-6 days faster than with BMT in four previously engrafting patients. Four patients died without platelet recovery after BCT within a year of BMT, three of treatment-related toxicity and one of relapse. Two patients developed grade II acute GVHD. Of six patients given BCT more than a year from BMT, four, all with acute leukemia, survive 7, 14, 29 and 29 months after BCT and one relapsed at 7 months. All four survivors developed chronic GVHD. These results indicate that BCT may be useful therapy for relapse occurring more than a year after BMT.  相似文献

PURPOSE/OBJECTIVES: To describe new bone marrow transplantation (BMT) options for chronic myelogenous leukemia (CML) and acute promyelocytic leukemia (APL), as well as their applications and prognoses, and to describe the role of the oncology nurse in caring for the BMT recipient and options for future nursing research. DATA SOURCES: Published articles, book chapters, and personal experience. DATA SYNTHESIS: Various pretransplant agents and methods are under investigation to improve the outcome and reduce the costs of allogeneic and autologous BMT and peripheral blood progenitor cell (PBPC) transplants. Preliminary results of current studies indicate that autologous BMTs and PBPC transplants have merit as a treatment option in patients with AML and require further research. For patients with APL, BMT usually is reserved for those who fail to achieve or relapse after achieving remission with chemotherapy. Preliminary data show that patients with CML and APL who receive a PBPC transplant engraft more rapidly with decreased morbidity and mortality. CONCLUSIONS: BMT options for patients with CML and APL continue to evolve as advances in pretransplant methods and symptom management become capable of improving the outcome, decreasing costs, and shifting patient care to the outpatient and homecare settings. IMPLICATIONS FOR NURSING PRACTICE: Understanding the marrow transplant options available to patients with CML and APL is essential for nurses. They must stay informed about ongoing improvements in pretransplant processes and symptom-management procedures that reduce BMT morbidity and mortality. Inpatient and outpatient nurses need to collaborate and participate in nursing research to find better ways of providing the best care possible for patients.  相似文献

The efficacy of allografting in acute lymphoblastic leukemia (ALL) is heavily influenced by remission status at the time of transplant. Using polymerase chain reaction (PCR)-based minimal residual disease (MRD) analysis, we have investigated retrospectively the impact of submicroscopic leukemia on outcome in 64 patients receiving allogeneic bone marrow transplantation (BMT) for childhood ALL. Remission BM specimens were taken 6 to 81 days (median, 23) before transplant. All patients received similar conditioning therapy; 50 received grafts from unrelated donors and 14 from related donors. Nineteen patients were transplanted in first complete remission (CR1) and 45 in second or subsequent CR. MRD was analyzed by PCR of Ig or T-cell receptor delta or gamma rearrangements, electrophoresis, and allele-specific oligoprobing. Samples were rated high-level positive (clonal band evident after electrophoresis; sensitivity 10(-2) to 10(-3)), low-level positive (MRD detected only after oligoprobing; sensitivity 10(-3) to 10(-5)), or negative. Excluding 8 patients transplanted in CR2 for isolated extramedullary relapse (all MRD-), MRD was detected at high level in 12 patients, low level in 11, and was undetectable in 33. Two-year event-free survival for these groups was 0%, 36%, and 73%, respectively (P <.001). Follow-up in patients remaining in continuing remission is 20 to 96 months (median, 35). These results suggest that MRD analysis could be used routinely in this setting. This would allow identification of patients with resistant leukemia (who may benefit from innovative BMT protocols) and of those with more responsive disease (who may be candidates for randomized trials of BMT versus modern intensive relapse chemotherapy).  相似文献

We report the clinical course of five adult patients with chronic Chagas' disease (Cd) who underwent BMT. Two patients with non-Hodgkin's lymphoma and one with ALL received an ABMT. Allogeneic BMT was performed in two patients with AML and CML respectively. One donor had chronic Cd. Samples of peripheral blood for parasite investigation by the Strout method, blood culture, and immunological studies by indirect immunofluorescent assay, ELISA and indirect hemagglutination tests were performed weekly from the start of chemotherapy until day +60 for ABMT and during the period of immunosuppression for allogeneic BMT. No prophylaxis was given to any of these patients. In only one ABMT patient were trypomastigotes detected early by blood culture without symptoms of reactivation. Benznidazole as preemptive treatment was administered at 5-8 mg/kg/daily for 30 days. Parasitemia was rapidly cleared and at the end of therapy xenodiagnosis was negative. The other Cd patients showed no evidence of relapse of parasitemia or signs and symptoms of reactivation. In brief, evidence of Cd should be sought in all BMT patients coming from endemic areas because parasitemia and reactivation are potential complications during the period of neutropenia and immunosuppression. The strategy used for early detection and treatment of parasitemia and reactivation was safe and effective.  相似文献
