Forty-six patients with non-Hodgkin's lymphoma (NHL) were treated with autologous bone marrow transplantation (ABMT) in two different institutions. All patients were pretreated with conventional chemotherapy. Three different conditioning regimens were used, and 20 patients underwent bone marrow purging. Twelve patients were treated in first complete remission (CR); eight are in unmaintained CR 8 to 104 months after ABMT. Five patients were grafted in first partial remission (PR) after conventional therapy; all achieved CR, and all remain in prolonged CR (first CR for four patients, second CR for one patient). Of 21 patients with chemosensitive relapses, 13 patients are in prolonged unmaintained CR 8 to 94 months after ABMT. Eight patients with resistant disease remained uncured by ABMT; all eight died, six from progressive illness and two from toxicity. The current 3-year disease-free probability is 60% for all patients, 0% for refractory disease; 82% for first PR or CR, and 60% for sensitive relapses (SRs). These results confirm the efficacy of ABMT in the treatment of chemosensitive NHL with bad prognosis.  相似文献

We report the safety and efficacy of autologous bone marrow transplantation (ABMT) in 30 patients with high-grade non-Hodgkin''s lymphoma (NHL) in first complete remission (CR1) following remission induction chemotherapy. Two patients relapsed prior to ABMT. All patients were conditioned with high-dose melphalan. In Addition, ten received fractionated total body irradiation, one hemi-body irradiation and four high-dose etoposide. Unmanipulated non-cryopreserved autologous marrow was reinfused within 56 h of harvesting. Engraftment occurred in all patients with a median of 11 days of neutropenia (< 0.5 x 10(9) l-1), a median requirement for platelet transfusion of 3 days and packed red cell transfusion of 2 units, with a median hospital stay of 18 days post transplant. There was no procedure-related mortality and only minor morbidity was observed. Two patients relapsed at 1 and 2 months post transplantation, and one patient died of carcinoma of the lung 33 months after transplantation. The remaining 25 patients remain alive, well and in CR1 with a median follow-up of 44 months. The event-free survival at 3 years for all patients considered for ABMT was 83%. We conclude that ABMT for high-grade NHL in CR1 with non-cryopreserved marrow results in rapid haematological recovery without growth factor support. It is safe and is associated with high survival when used as consolidation of CR in high-risk patients.  相似文献

We prospectively assessed autologous stem cell transplantation for consolidation treatment in a trial of intensive chemotherapy in high risk myelodysplastic syndromes (MDS). In this trial, patients aged 55 years or less with no HLA-identical sibling and achieving CR were scheduled to receive unmanipulated autologous bone marrow transplantation (ABMT) preceded by a consolidation chemotherapy course. Forty-two of the 83 patients aged 55 years or less included in the trial (51%) achieved CR. Three were allografted in CR. Twenty-four of the remaining 39 patients who achieved CR (62%) received ABMT (16 patients) or autologous peripheral blood stem cell transplantation (APSCT) (eight patients). Indeed, as bone marrow harvest was often insufficient, APSCT was subsequently proposed after mobilization by consolidation chemotherapy followed by G-CSF. The conditioning regimen combined cyclophosphamide and busulfan. ABMT and APSCT were performed 1-7 months (median 3) after CR achievement. Hematological reconstitution occurred in all patients and tended to be faster after APSCT than ABMT although not significantly. Three patients died from the procedure, nine relapsed after 2-26 months and 12 (50%) were still in CR after 8-55 months. In autografted patients, median Kaplan-Meier disease-free survival and survival were 29 and 33 months from the autograft, respectively. Thus, ABMT or APSCT can be performed in almost two-thirds of MDS patients who achieve CR with intensive chemotherapy. PBSC collection may yield higher numbers of stem cells than marrow collection in some cases, and could improve the percentage of MDS patients autografted in CR. Longer follow-up is required to determine if autograft will prolong CR duration in at least some patients.  相似文献

BACKGROUND:: Patients with Hodgkin's disease (HD) and intermediate or high-gradenon-Hodgkin's lymphoma (NHL) who fail to achieve a completeremission (CR) with standard induction therapy have a poor prognosiswith conventional-dose salvage therapy alone. We examined therole of subsequent intensive therapy and autologous bone marrowtransplantation (ABMT) in patients who demonstrated a responseto conventional-dose salvage therapy. PATIENTS AND METHODS:: Sixty-six patients with either HD (n = 30) or NHL (n = 36) underwentintensive therapy with etoposide (60 mg/kg), intravenous melphalan(160–180 mg/m2) followed by infusion of unpurged autologousbone marrow and/or blood cells. All patients had advanced stageor bulky disease at diagnosis and failed to achieve a CR afteran anthracycline-containing front-line chemotherapy regimen(NHL) or ABVD or equivalent regimen (HD). Patients who achieveda CR after involved-field radiotherapy were excluded. All patientsdemonstrated sensitivity to conventionaldose salvage treatmentbefore advancing to intensive therapy and ABMT. RESULTS:: The CR, partial response (PR) and overall response rate (RR)following ABMT for HD patients was 48%, 17% and 65%, respectively.At a median follow-up of 35 months, the predicted three-yearoverall survival (OS) is 51% (95% CI: 44%–60%) and event-freesurvival (EFS) is 34% (95% CI: 26%–54%). For patientswith NHL, the CR, PR and RR were 68%, 9% and 77%, respectively.At a median follow-up of 28 months, the predicted three-yearOS is 51% (95% CI: 35%–66%) and EFS is 39%(95% CI: 21%–57%). CONCLUSIONS:: Intensive therapy with etoposide and melphalan followed by ABMTresults in prolonged survival in selected patients with lymphomawho fail to achieve a complete remission to front-line chemotherapy.Based on our previous studies of outcome to conventionaldosesalvage chemotherapy, we estimate that of all patients failinginduction therapy, 28% with HD and 15% with NHL will be eventfreeat three years after ABMT. induction failure, Hodglun's disease, non-Hodgkin's lymphoma, refractory lymphoma  相似文献

From October 1984 to November 1987, 34 patients aged from 1 year 1 month to 7 years 7 months with resistant or relapsed neuroblastoma (NB) (group 1, 10 patients), unselected disseminated NB (group 2, 14 patients), or selected disseminated NB (group 3, 10 patients) received myeloablative therapy (MAT) followed by unpurged autologous bone marrow transplantation (ABMT) at the end of an intensive protocol, which included high-dose chemotherapy and surgery to the primary tumor. Median time from diagnosis to MAT and ABMT was 6 months (5 months from last relapse to MAT and ABMT in the relapsed patients). The MAT regimen included vincristine, fractionated total body irradiation (TBI), and melphalan. Seventeen patients were grafted in complete remission (CR), five in very good partial remission (VGPR), 10 in partial remission (PR), and two in progressive disease (PD). The acute toxic death rate was 2.9%. The overall progression-free survival was 29%. The median progression-free survival was 20 months for the 17 patients grafted in CR, 6 months for the five patients grafted in VGPR, and 12 months for the 10 patients grafted in PR.  相似文献

Fifty-one patients with relapsed or refractory intermediate- or high-grade non-Hodgkin's lymphoma were referred for autologous bone marrow transplantation (ABMT). The primary criterion for eligibility was sensitivity to conventional-dose salvage chemotherapy. Of 47 patients who received salvage chemotherapy, 30 demonstrated chemotherapy-sensitive disease. Six eligible patients did not undergo ABMT for various reasons. A total of 24 patients underwent ABMT, with etoposide, melphalan ± total body irradiation as the intensive therapy regimen. There was one early treatment-related death and three non-responders. Of the remaining patients, 9 relapsed, while 11 remain in continuous complete remission (CR) at a median follow-up of 21 months after transplant (range 5-37 months). Two patients with chemosensitive disease and bone marrow involvement underwent allogeneic BMT with marrow from HLA-identical siblings. Both are in continuous CR at 6 and 12 months follow-up. Of the 25 patients who did not undergo ABMT, all have died (median survival 5 months).

The results indicate that approximately one-half of relapsed or refractory aggressive histology lymphoma patients referred for ABMT eventually undergo transplantation, if chemotherapy-sensitive relapse is the major criterion for eligibility. Approximately 25% of the referred patients may become long-term disease-free survivors with this approach. Reports of marrow transplant series should include all patients referred for ABMT as the denominator for calculating disease-free survival in order to reduce the bias of patient selection.  相似文献

A 5-yr experience of massive therapy and autologous bone marrow transplantation (ABMT) for Burkitt's lymphoma is reviewed. Thirty courses were given to 28 patients. Three patients were in resistant relapse and all three died before day 54 post ABMT. Thirteen patients were in non-resistant relapse and seven are alive with non-evidence of disease (NED). All three patients grafted in partial remission (PR) are alive NED including two with initial central nervous system (CNS) disease. Nine patients were grafted in 1st complete remission (CR) either because of long delay to achieve CR [3] or as consolidation in those with initial CNS involvement [5] or leukaemia [1]. Three of these nine are alive including 23 with a long delay to CR and 15 initial CNS. The overall survival NED for the 28 patients is 46%. The median observation time post ABMT, 22 months.Clear indications for ABM T in BL are in our opinion restricted to about 20% of the patients: non-resistant relapses and PR after initial induction therapy. Massive therapy as consolidation of 1st CR after initial CNS involvement and in resistant relapses should still be considered as experimental. In 14 patients whose marrow was purged there is laboratory evidence suggesting that the purging procedures used in this study may have been incomplete. Purging techniques still require perfection at a laboratory level and their rationale should not be judged on the basis of incomplete procedures.  相似文献

Summary Twenty-six patients (median age 33 years) with poor-risk malignancies were treated with high-dose combination chemotherapy associating BCNU-etoposide-cytosine arabinoside and melphalan (BEAM) followed by autologous bone marrow transplantation (ABMT). Twenty-one patients had malignant lymphomas, three, acute lymphoblastic leukemia (ALL), and two, malignant thymomas. Eleven patients (group 1) were not in complete remission (CR) at the time of BEAM, and fifteen patients (group 2) were in CR. Hematological recovery occurred in all patients. The duration of aplasia and the non-hematological toxicities were similar in both groups. Ten of the eleven patients (group 1) evaluable for response achieved CR and one achieved partial remission (PR). Five patients relapsed, and five are in continuous CR with a short follow-up (median 8 months). Among the fifteen patients in CR at the time of BEAM (group 2), four patients relapsed and ten patients are in unmaintained continuous CR with a median follow-up of 15 months (one patient died in CR). The disease-free survival is 53%, with 29% for patients receiving BEAM while in relapse (group 1) and 65% for patients receiving BEAM while in CR (group 2). These data indicate that BEAM followed by ABMT can produce a high antitumor response with an acceptable toxicity in patients with poor-risk malignancies.  相似文献

Since January 1983, 56 consecutive children over 1 year of age with stage IV neuroblastoma entered an aggressive protocol, including chemotherapy, radiation therapy, and bone marrow transplantation. The induction protocol included platinum and epipodophyllotoxin (VM-26), alternating with cyclophosphamide, Adriamycin (Adria Laboratories, Columbus, OH), and vincristine (PE/CADO). Surgery was performed after 2 to 4 months, and consolidation with intensive chemoradiotherapy and bone marrow transplantation (BMT) was performed within 12 months of diagnosis. The combination of vincristine, melphalan and total body irradiation (TBI) was used before BMT, and no further treatment was administered before progression. With the exception of two allografts, autologous BMT (ABMT) was given in all cases and was purged using an immunomagnetic procedure (Kemshead technique) in 32 of 35 cases, and a chemical procedure in three of 35. Of the 56 patients, 45 were evaluable. Of those, 23 were grafted in partial remission (PR), and 14 were grafted in either complete remission (CR) or very good partial remission (VGPR). The acute toxic death rate was 19%, the relapse rate was 32%, and the progressive disease rate was 19%. The progression-free survival in the CR/VGPR group (ie, 44% at 32 months post-diagnosis) and in the PR group (13% at 32 months) was not significantly different (P greater than .05). At 24 months, the overall survival of the 56 unselected patients was 39% compared with 12% for comparable patients previously treated by our group (P less than .005).  相似文献

PURPOSE: To evaluate the use of high-dose busulfan (HDB) with autologous bone marrow transplantation (ABMT) in patients with myeloma. PATIENTS AND METHODS: Fifteen patients received HDB (16 mg/kg), eight of whom received high-dose melphalan (HDM) but had experienced a short remission or progression-free interval. Two patients had received HDM on two previous occasions, one had no response to low-dose melphalan, and four had impaired renal function (edathamil clearance < 40 mL/min). All patients received induction chemotherapy before HDB. RESULTS: Two patients were in complete remission (CR) after induction chemotherapy before HDB. Of the remaining 13 patients, four (31%) achieved CR and two (15%) achieved a partial remission for an overall response rate of 46%. There were three treatment-related deaths, but the toxicity was otherwise predictable and manageable. CONCLUSIONS: In heavily pretreated patients, HDB results in a relatively high response rate. It can also be used safely in patients with renal impairment who are not suitable for HDM.  相似文献

Summary Fifteen children with advanced neuroblastoma according to Evans' classification (1 with stage III and 14 with stage IV) were treated with high-dose melphalan (HDM) followed by autologous bone marrow transplantation. Before HDM, all patients had been extensively treated with multimodality therapy for a median duration of 9 months. At the time of HDM, seven children were in partial remission (PR) with measurable residual tumor and 8 were in complete remission (CR) or good partial remission (GPR). No reduction in measurable tumor size was observed in any of the PR patients. However, when HDM was used as consolidation therapy (CR and GPR patients) survival appeared encouraging, since five of eight patients are alive with no evidence of disease at (NED) 29+ to 54+ mouths after HDM. Tolerance of this high-dose chemotherapy was satisfactory; gastrointestinal toxicity appeared to be the most important limiting factor. These results suggest that chemotherapy including high-dose melphalan is promising when used as consolidation therapy in patients who have already attained CR with conventional therapies.This study was presented in part at the workshop on high-dose chemotherapy with autologous bone marrow transplant.

Background: Disease status before high-dose chemotherapy with autologous bone marrow transplantation (ABMT) or peripheral blood stem cell transplantation (PBSCT) is an important predictor of transplantation-related toxicity and event-free survival (EFS) for patients with relapsed or refractory Hodgkin's disease (HD). We performed a phase II study in patients with relapsed or refractory HD to evaluate the feasibility of four cycles of Dexa-BEAM followed by high-dose chemotherapy with ABMT or PBSCT.Patients and methods: Twenty-six patients (median age 30, range 20–40 years) were treated with 2–4 courses of dexamethasone, carmustine, etoposide, cytarabine and melphalan (Dexa-BEAM) as salvage chemotherapy in order to attain maximal response. Patients achieving complete response (CR) or partial response (PR) received high-dose chemotherapy with ABMT or PBSCT. The conditioning regimen used was CVB (cyclophosphamide, carmustine, etoposide).Results: Eighteen patients responded to Dexa-BEAM, resulting in a response rate of 69%. At the time of transplant 16 patients were in CR two patients in PR. At present 14 patients transplanted are in continous CR (median follow-up 40 months, range 14–60 months). Two patients with PR after four courses of Dexa-BEAM relapsed and died three months posttransplantation. Two patients with CR at the time of transplant relapsed after nine and 13 months respectively. Eight patients had rapid progressive disease after 2–4 cycles of Dexa-BEAM. One patient with progressive disease died in gram-negative sepsis after four cycles of Dexa-BEAM. There was no transplantation-related death.Conclusion: These data suggests the use of high-dose chemotherapy followed by stem cell transplantation at the time of maximal response.  相似文献

Of 52 children aged 9 months to 16 years old with acute myelogenous leukaemia (AML) in first complete remission undergoing bone marrow transplantation at our institution, 31 received allogeneic transplants (allo-BMT) and 21 received autologous transplants (ABMT). Initial induction and consolidation chemotherapy were not uniform. BMT was performed at a median of 7 months (range: 2.5 to 22.5 months) from the diagnosis. Conditioning included chemotherapy (n=43: 4 x 4 mg/kg of busulfan and 3 x 60 to 70 mg/m(2) of melphalan) or total body irradiation (12 Gy) plus chemotherapy (n=9). Graft-versus-host disease (GVHD) prophylaxis in allo-BMT cases consisted of methotrexate +/- cyclosporin A. Unpurged marrow was used in ABMT cases. All patients showed sustained engraftment. Amongst allograft cases, acute or chronic GVHD developed in 7 patients each (23%). 8 patients (15%) died (5 with allo-BMT, 3 with ABMT), including transplant-related mortality in 3 of the allo-BMT patients. 7 patients had relapses (3 with allo-BMT, 4 with ABMT). As of June 1999, 43 patients are alive and well 13 to 160 months after BMT (median, 71), with 5-year disease-free survival rates after BMT of 84% for allo-BMT, 81% for ABMT and 83% altogether. Although the presented data are based on a retrospective evaluation, we consider BMT for childhood AML during first complete remission an effective treatment for eradicating leukaemia.  相似文献

Long-term disease-free survival after conventional dose salvage chemotherapy for relapsed or refractory non-Hodgkin's lymphoma (NHL) or Hodgkin's disease (HD) is rare. Intensive chemotherapy and autologous bone marrow transplantation (ABMT) is regarded by many as the treatment of choice. For lymphoma, eligibility for transplant is frequently restricted to cases with chemotherapy-sensitive disease or minimal tumour bulk. We evaluated the mini-BEAM regimen as further treatment for patients unresponsive to initial salvage therapy and thus ineligible for ABMT at our centre. Carmustine 60 mg/m(2) I.V. day one, etoposide 75 mg/m(2) I.V. days 2-5, cytosine arabinoside 100 mg/m(2) I.V. q12h days 2-5 and melphalan 30 mg/m(2) day 6 (mini-BEAM) was administered to 24 patients with lymphoma, 22 of whom were refractory to at least first-line salvage chemotherapy. Eleven had HD and 13 NHL. The complete response (CR) rate was 21% and the overall response was 59%. Febrile neutropenia occurred in 48% of treatment episodes. There were two treatment-related deaths. Thirteen patients underwent bone marrow transplantation (BMT), 11 received ABMT (8 HD, 3 NHL). Six patients did not achieve remission after transplant but 7 patients remain in continuous CR, with a follow-up of 6-17 months post-transplant. Consequently, 7 of 24 (29%) patients responded to mini-BEAM and many achieve long-term disease-free survival after BMT. Further evaluation of mini-BEAM as a salvage regimen prior to BMT is indicated.  相似文献

This study aimed to assess the safety and efficacy of using high dose melphalan and etoposide followed by autologous, non-cryopreserved marrow rescue in advanced Hodgkin''s disease (HD). Seventeen patients with poor risk Hodgkin''s disease from a single centre underwent autologous bone marrow transplant (ABMT) using high dose melphalan and etopside conditioning. Two patients had primary progressive resistant disease (PD), two were in fourth relapse, six in second or third complete remission (CR), one patient had good partial response (GPR) (> 75% reduction in initial bulk) to primary therapy and six were in first complete remission. The patients transplanted in first CR all has a Scotland and Newcastle Lymphoma Group (SNLG) Prognostic Index (Proctor et al., 1991) which indicated they were in a poor risk prognostic group. Melphalan and etoposide both have a short half life enabling ABMT to be accomplished using unmanipulated marrow stored at 4 degrees C. The marrow was returned to the patient within 56 h of harvest. Complete haematological reconstitution occurred in 16/17 patients, the rate of engraftment reflecting the amount of previous chemotherapy. One patient died of progressive Hodgkin''s disease before full engraftment could occur. In patients autografted in first remission, the median number of days with neutropenia (< 0.5 x 10(9) l-1 neutrophils) was 19 (range 9-33) and, in those in subsequent remission, 27 days (range 18-36). The median number of days to 50 x 10(9) l-1 platelets in the same groups were 29 (21-80) and 50 (41-74) respectively. The number of days in hospital post transplant in both groups was similar; median 22 (15-27) and 23 (17-37) respectively. There were no procedural deaths and none of the patients transplanted in first, second or third CR have relapsed (median follow up 21 months). The two patients transplanted with progressive disease showed only temporary responses. The two patients transplanted in fourth relapse went into CR; one is still alive and in CR 15 months post transplant, but the other relapsed 18 months post transplant. This form of intensification therapy with marrow rescue has been shown to be effective and of low toxicity and now forms part of a randomised controlled trial in poor risk Hodgkin''s patients as identified by the SNLG index (Proctor et al., 1992).  相似文献

Purpose:to study response to chemotherapy and the outcome ofchildren treated for a relapsed anaplastic large-cell lymphoma (ALCL) and toevaluate the role of bone marrow transplantation (BMT) in these patients. Patients and methods:Clinical data concerning the 41 relapsesthat occurred in 119 patients with ALCL enrolled in 3 consecutive studiessince 1975 were analysed. First-line treatment consisted of intensivechemotherapy according to the COPAD protocol for the first series of 12patients treated between 1975 and 1989 and to the SFOP (French Society ofPediatric Oncology) HM protocols for the 30 patients treated between 1989 and1997. Twenty-eight patients were treated with CV(B)A (CCNU, vinblastine, ara-Cwith or without bleomycin), and the others with miscellaneous protocols forrecurrent disease. Fifteen patients underwent autologous BMT and 1 allogeneicBMT while in CR2. Results:Thirty-six of forty-one (88%) patients achievedCR2. With a median follow-up of 5 years, 12 patients died, 9 of their diseaseand 29 patients are alive in CR2 (20 patients), CR3 (5 patients), CR4 (2patients), CR5 (1 patient) or CR6 (1 patient). Overall and disease-freesurvival are respectively 69% (53%–82%) and44% (29%–61%) at three years. In univariateanalysis, patients treated with ABMT while in CR2 did not appear to have abetter outcome than the other. Remarkably, a long-lasting remission wasobtained in 8 of 13 patients treated with weekly vinblastine for a relapseincluding 6 relapses occurring after ABMT. Conclusions:Relapsed ALCL are highly chemosensitive but over40% of the patients experience several relapses. Prolonged conventionalchemotherapy based on vinblastine might, in some cases, be as efficient asshort intensive treatment with ABMT.  相似文献

Sixty-one patients with relapsed Hodgkin's disease who had failed a mechlorethamine, vincristine, procarbazine, and prednisone (MOPP)- and a doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD)-like regimen were treated with a high-dose combination chemotherapy containing cyclophosphamide, carmustine, and etoposide (CBV) and autologous bone marrow transplantation (ABMT). Fifty-nine patients were treated in relapse and two were intensified early in third remission. Following therapy, 29 patients (47%) were in complete remission (CR), 18 patients (30%) achieved a partial response (PR), and 14 patients (23%) had progressive disease (PD). Among the partial responders, six patients achieved a CR following addition of local radiation therapy to sites of residual nodal disease. For a minimum follow-up of 2 years, 23 patients (38%) are alive and free of disease. High-dose CBV therapy produced severe myelosuppression, and there were four (7%) treatment-related deaths. A multivariate analysis identified failure of more than two prior chemotherapy treatments and poor performance status as important adverse risk factors for survival. Patients who had no adverse risk factor and/or were intensified with CBV while Hodgkin's disease was still responding to conventional chemotherapy, had a CR rate of 63%, with 77% projected 3-year survival; whereas, all other patients had a CR rate of 31%, and a projected 3-year survival of only 18%. Our results demonstrated that CBV and ABMT can induce remission duration of 2 years or greater in a significant proportion of patients with relapsed Hodgkin's disease.  相似文献

 耐药和复发的何杰金氏病(HD)是否该作自体骨髓移值(ABMT)仍是颇有争议的问题。剂量强度与疗效的关系是ABMT的理论基础。本文研究了1982~1994年间有关HD挽救化疗资料中的剂量强度与疗效关系,没有得出所希望的结论。但常规化疗的结果并不满意,Ⅲ线方案的CR率仅23%。ABMT在Ⅱ线方案失败的患者中有很强适应症。  相似文献

Fifty patients were studied. Twenty patients with non-Hodgkin's lymphomas (NHL) of high-grade malignancy and 21 patients with acute leukemia (AL) were treated with high-dose cyclophosphamide and total body irradiation, and three patients with Hodgkin's disease (HD) and six patients with solid tumors were treated with high-dose cyclophosphamide and VP16-213. Those procedures were followed by autologous bone marrow transplantation (ABMT). All patients had received conventional chemo(radio)therapy before the ABMT procedure. Although remissions were obtained in patients with cytotoxic drug-resistant diseases (lymphomas and solid tumors), none has become a long-term survivor, as occurred also in patients with solid tumors in partial remission (PR). Two of five patients with NHL in PR at the time of ABMT have become long-term disease-free survivors (28+, 56+ months). Ten patients with NHL were treated in complete remission (CR) and seven are in unmaintained CR; four with long follow-up (14+ to 59+ months). All patients with AL were treated in CR; two patients received ABMT in second CR, and both relapsed. Ten of nineteen patients in first CR relapsed; eight are alive in CR, five with long follow-up. Four deaths were therapy-related, all were patients in poor clinical condition. Intensive cytoreductive therapy followed by ABMT can produce prolonged disease-free survival (and probably cure) in a fair number of patients with poor risk NHL in CR and PR and probably also in patients with acute myeloblastic leukemia in first CR. This procedure was not successful in achieving long-term disease-free survival in patients with refractory lymphomas or solid tumors.  相似文献

Among 62 children over 1 year of age at diagnosis, who were treated for stage IV neuroblastoma, 33 entered complete remission (CR) or good partial remission (GPR) after conventional therapy and received high-dose chemotherapy (HDC) with in vitro purged autologous bone marrow transplantation (ABMT) as consolidation therapy. The HDC was a combination of carmustine (BCNU), teniposide (VM-26), and melphalan. Thirty-three patients received one course of this regimen, and 18 received two courses. At present, 16 of the 33 grafted patients are alive in continuous CR, with a median follow-up of 28 months. Toxicity of this regimen was tolerable, principally marked by bone marrow depression and gastrointestinal (GI) tract complications. Four complication-related deaths were observed. Relapse post-ABMT occurred most often in the bone marrow. Under this treatment, actuarial disease-free survival is improved compared with that observed under conventional therapy.  相似文献
