Extramedullary relapse (EMR) represents a poor prognostic marker in the course of multiple myeloma (MM). We reviewed data from 329 patients, diagnosed between 2000 and 2010, without extramedullary disease at onset to explore possible risk factors for EMR. The median overall survival of our study cohort was 6.4 years. The risk of EMR was 28 % with a median time from diagnosis to first EMR of 2.2 years (0.2–9.1 years). Patients with soft tissue masses located in extra-osseous organs (EMR-S) showed the worst outcome, compared to those with tumor masses arising from adjacent bone (EMR-B) (median OS 1.6 vs 2.4 years, p?=?0.006). In addition, patients with EMR-S showed a significant trend for further development of extramedullary masses in a very short time (3.7 vs 5.7 months for EMR-B, p?=?0.043). Multivariate analysis failed to identify any clinically presenting features predictive for EMR. The occurrence of EMR was higher in patients with more complex treatment history, defined on the basis of longer treatment duration (≥6 vs <6 months) and on elevated number of treatment lines administered (>2 vs ≤2 lines) (HR?=?4.5, p?<?0.001 and HR?=?9.0, p?<?0.001, respectively, when one or both factors are present).In conclusion, increasing burden of treatment might be a possible risk factor for EMR. MM patients with multiple relapses should be comprehensively investigated including, when possible, a whole-body-targeted radiologic technique to accurately detect EMR. Treatment choice should take into account the very poor outcome for patients with soft tissue involvement. 相似文献

Treatment options for patients with myeloma who relapse after allogeneic stem cell transplantation are limited. Thalidomide, an antineoplastic agent, has been shown to be effective in multiple myeloma through proposed mechanisms that may include angiogenesis inhibition. Herein we report successful thalidomide treatment of four patients who relapsed following allogeneic transplantation, three of whom had predominantly extramedullary relapse. Thalidomide was well tolerated in all patients; in two patients interferon-alpha was subsequently added to thalidomide as maintenance therapy without worsening graft-versus-host disease. We suggest that extramedullary myeloma is particularly sensitive to thalidomide, speculating that growth biology may in part be dependent on angiogenesis. 相似文献

We aimed to compare the characteristics of skeletal and soft tissue plasmacytomas and to analyze clinical outcomes and prognostic factors of autologous stem cell transplantation (ASCT) in multiple myeloma (MM) patients with plasmacytoma. We retrospectively reviewed data from 93 myeloma patients with detectable extramedullary (EM) plasmacytoma at diagnosis or during the course of the disease, who underwent ASCT. Soft tissue plasmacytoma occurred more frequently in male patients and had higher levels of serum β2‐microglobulin and lactate dehydrogenase and high frequency of advanced disease according to International Staging System compared to the skeletal plasmacytoma group. Both soft tissue and skeletal plasmacytoma groups showed similar plasmacytoma relapse patterns after ASCT and relapsed with EM plasmacytoma slightly more frequently in the bone compared to soft tissue sites. Compared to patients with skeletal plasmacytoma, patients with soft tissue plasmacytoma had worse median progression‐free survival (PFS) (12 vs. 28 months) (P = 0.001) and overall survival (OS) (37 vs. 67 months) (P = 0.037) after ASCT. In a multivariate analysis, soft tissue plasmacytoma was an only independent poor prognostic factor for both PFS (HR, 2.398; 95% CI, 1.304–4.410) and OS (HR, 2.811; 95% CI, 1.107–7.135) after ASCT. These results demonstrate that, even though ASCT achieved a strong response in myeloma patients with soft tissue plasmacytoma, the presence of EM disease still contributed to a poor prognosis after ASCT compared to skeletal plasmacytoma, and these poor outcomes were not overcome by ASCT. 相似文献

Bortezomib is a potent and selective proteasome inhibitor recently introduced in the treatment of multiple myeloma (MM). This drug produces significant responses in about one-third of patients with relapsed/refractory disease. We first recognized the lack of efficacy of thalidomide in soft-tissue plasmacytomas. There is little information on the effect of bortezomib on extramedullary myeloma. Four of 23 patients treated with bortezomib at our institution had extramedullary involvement at the time of relapse. In three of these patients large soft-tissue plasmacytomas disappeared. This indicates that bortezomib may be useful in clinical situations of extramedullary disease in which other agents, such as thalidomide, may not be effective. 相似文献

Extramedullary relapses of multiple myeloma (MM) during the course of disease are rare. We report a series of six patients with primary intramedullary MM that were treated with immunomodulatory therapy and/or stem cell transplant, and that later developed extramedullary relapses at various body sites. These six cases represent 3.9% of the 156 patients treated for MM at our institution over a 9-yr period (1999-2007). Five (83.3%) of the six cases showed immature/high-grade histology in the extramedullary relapses as compared with their antecedent MM. The neural cell adhesion molecule, CD56, was immunohistochemically demonstrable in 75% (three of four) of the original myelomas tested, but was absent in 83.3% (five of six) of their extramedullary relapses. The disease typically behaved aggressively and was rapidly fatal in all six patients even when therapy was administered. The median time of progression to extramedullary relapse was 29 months (range 9-64 months), and the median survival after diagnosis of the relapses was only 38 d (range 1-106 d). Our case series shows that extramedullary relapse of MM is characterized by high-grade histology, loss of CD56 expression, frequent resistance to current therapeutic regimens, aggressive biological behavior, and very short survival. 相似文献

In the course of multiple myeloma, patients may develop a M-protein band different from the original: secondary monoclonal gammopathy of undetermined significance. In this retrospective single center analysis, we describe the occurrence and clinical relevance of secondary monoclonal gammopathy of undetermined significance after allogeneic stem cell transplantation (post-transplant monoclonal gammopathy of undetermined significance). A total of 138 patients who had undergone 139 allogeneic stem cell transplantations (39.6% in the upfront setting and 60.4% for relapsed multiple myeloma) were included in the study. Sixty-seven (48.2%) patients developed secondary monoclonal gammopathy of undetermined significance, after a median latency of 6.9 months. Secondary monoclonal gammopathy of undetermined significance occurred more often in patients who achieved at least very good partial response after allogeneic stem cell transplantation, compared to partial response or less (54.8% vs. 26.5%; P=0.005). The incidence was also higher in the upfront setting as compared to relapsed disease, or with a sibling donor compared to matched unrelated donor, but less often after T-cell depletion. Importantly, development of post-transplant monoclonal gammopathy of undetermined significance as a time-dependent variable independently predicted for superior progression-free and overall survival (median progression-free survival 37.5 vs. 6.3 months, P<0.001; median overall survival 115.3 vs. 31.0 months, P=0.004). Clinicians should be aware of the benign nature of this phenomenon, and secondary monoclonal gammopathy of undetermined significance should not be confused with relapse or progression of disease.

Recent literature suggests that after non-myeloablative allogeneic (NMA) stem cell transplantation (SCT), the incidence of extramedullary (EM) relapse in multiple myeloma (MM) patients is increased and that these relapses have a poor prognosis. However, numbers on incidence and treatment outcome are scarce. We collected data from 54 relapsed MM patients from a total group of 172 treated with sequential autologous and allogeneic NMA SCT at seven transplantation centres. There were 43 (79.6%) systemic relapses, including 6 with concurrent EM localisation. Five patients had a local EM relapse only. Six patients relapsed with only bone involvement. Patients with deletion of chromosome 13 had a higher incidence of EM relapse (30.8 versus 5.6%, P=0.06). EM relapses were treated with donor lymphocyte infusion, radiotherapy, or chemotherapy, especially with novel agents. The response rate was 45.5%, which was not different when compared to patients without EM disease (54.1%). Overall survival and progression-free survival were not significantly different in patients with EM disease, when compared to those without EM disease. In conclusion, the incidence of relapse with EM disease following allogeneic NMA SCT was 20.4%. There was no negative impact of EM relapse on response rate, overall survival and progression-free survival. 相似文献

Acute lymphoblastic leukemia (ALL) can relapse in the extramedullary compartment, with or without medullary involvement. Response to treatment may be individual. We evaluated response to inotuzumab ozogamicin in 31 patients with relapsed/refractory B-ALL with extramedullary disease. Median age was 31 years (range, 19-81). All patients were heavily pretreated, including allogeneic hematopoietic stem cell transplantation (HSCT; n=18). Overall response rate after two cycles of inotuzumab ozogamicin was 84% (complete remission, 55%; partial remission, 29%; resistant disease, 13%; early death, 3%). The median follow-up was 29 months and median overall survival was 12.8 months. One-year and 2-year overall survival rates were 53% (95% CI: 37-76%) and 18% (95% CI: 8-43%), respectively. Age had no impact on overall survival when assessed as a continuous variable or dichotomized at 60 years. Twelve patients proceeded to allogeneic HSCT (complete remission, n=6; partial remission, n=3; resistant disease, n=3). Prior to allogeneic HSCT, eight patients received two or fewer cycles and four patients received three or four cycles of inotuzumab ozogamicin. Sinusoidal obstruction syndrome was reported in three patients, including one after transplantation. Allogeneic HSCT, evaluated as a time-dependent variable, had no impact on overall survival. Inotuzumab ozogamicin seems to be effective as a debulking strategy in relapsed/refractory ALL with extramedullary disease. However, inotuzumab ozogamicin followed by allogeneic HSCT seems not to be effective in maintaining long-term disease control. 相似文献

Background
The prognosis of patients with relapses of ETV6/RUNX1-positive acute lymphoblastic leukemia remains to be evaluated, particularly with regards to the frequency of late relapses. We performed a long-term, follow-up retrospective study to address the outcome of patients with ETV6/RUNX1-positive leukemia relapses.Design and Methods
Among the 713 children tested for ETV6/RUNX1 enrolled into the FRALLE 93 protocol, 43 ETV6/RUNX1-positive patients relapsed (19.4%). Most were initially stratified in the low or intermediate risk groups. The median follow-up after relapse was 54.2 months. All but three received second-line salvage therapy and 16 underwent allogeneic transplantation.Results
ETV6/RUNX1 had a strong effect on overall survival after relapse (3-year survival= 64.7% for positive cases versus 46.5% for negative cases) (P=0.007). The 5-year cumulative incidence of relapse was 19.4% and testes were more frequently involved in ETV6/RUNX1-positive relapses (P=0.04). In 81.4% of cases the relapses were late, early combined or isolated extramedullary relapses. The 5-year survival rate of patients with ETV6-RUNX1-positive acute lymphoblastic leukemia relapses reached 80.8% when the relapse occurred after 36 months (versus 31.2% when the relapse occurred earlier). In univariate analysis, female gender was associated with a poor survival, whereas site of relapse, age at diagnosis, leukocytosis and consolidation strategy had no effect. In multivariate analysis, only the duration of first remission remained associated with outcome.Conclusions
We found an excellent outcome for patients with ETV6/RUNX1-positive leukemia relapses that occurred more than 36 months after diagnosis. The duration of first complete remission may, therefore, be a guide to define the treatment strategy for patients with relapsed ETV6/RUNX1- positive leukemia.

Treatments for myeloma have expanded in the last decade, but it is not clear if the introduction of novel therapies and the increased use of high-dose therapy have translated into better outcome for patients with myeloma. We examined the outcome of 2 groups of patients seen at a single institution, one from time of diagnosis and the other from the time of relapse, to examine the survival trends over time. Among 387 patients relapsing after stem-cell transplantation, a clear improvement in overall survival from the time of relapse was seen, with those relapsing after 2000 having a median overall survival of 23.9 versus 11.8 months (P < .001) for those who relapsed prior to this date. This improvement was independent of other prognostic factors. Patients treated with one or more of the newer drugs (thalidomide, lenalidomide, bortezomib) had longer survival from relapse (30.9 vs 14.8 months; P < .001). In a larger group of 2981 patients with newly diagnosed myeloma, those diagnosed in the last decade had a 50% improvement in overall survival (44.8 vs 29.9 months; P < .001). In this study, we demonstrate improved outcome of patients with myeloma in recent years, both in the relapsed setting as well as at diagnosis. 相似文献

The current study assesses the characteristics and outcomes of multiple myeloma (MM) patients, treated with novel agents for hematogenous extramedullary (HEMM) relapse. Consecutive patients diagnosed with HEMM between 2010-2018 were included. Patients' characteristics at diagnosis and at HEMM presentation, response to treatment, survival and factors predicting survival were recorded and analyzed. A group of 127 patients, all diagnosed with HEMM by imaging (87.3%) and/or biopsy (79%), were included. Of those, 44% were initially diagnosed with ISS3, 57% presented with plasmacytomas, and 30% had high-risk cytogenetics. Median time to HEMM was 32 months. In multivariate analysis, ISS3 and bone plasmacytoma predicted shorter time to HEMM (P = .005 and P = .008, respectively). Upfront autograft was associated with longer time to HEMM (P = .002). At HEMM, 32% of patients had no BM plasmacytosis, 20% had non-secretory disease and 43% had light-chain disease. Multiple HEMM sites were reported in 52% of patients, mostly involving soft tissue, skin (29%), and pleura/lung (25%). First treatment for HEMM included proteasome inhibitors (50%), immunomodulatory drugs (IMiDs) (39%), monoclonal antibodies (10%), and chemotherapy (53%). Overall response rate (ORR) was 57%. IMiDs were associated with higher ORR (HR 2.2, 95% CI 1.02-4.7, P = .04). Median survival from HEMM was 6 months (CI 95% 4.8-7.2). Failure to achieve ≥VGPR was the only significant factor for worse OS in multivariate analyses (HR = 9.87, CI 95% 2.35 - 39, P = .001). In conclusion, HEMM occurs within 3 years of initial myeloma diagnosis and is associated with dismal outcome. The IMiDs might provide a higher response rate, and achievement of ≥VGPR predicts longer survival. 相似文献

Extramedullary (e) relapse in multiple myeloma(MM) has an adverse prognosis, but knowledge concerning biological features and preferred treatment is scarce. We screened the myeloma registry of our institution for eMM relapses and identified 24 cases among 357 patients (pts).Only 8% of eMM relapses occurred after initial therapy, but 54% occurred after third-line or subsequent therapy. Baseline molecular cytogenetics revealed high-risk features in 10 of 19 evaluable patients. Most frequently, eMM presented as soft tissue (67%) and organ involvement (25%) or malignant effusion (12.5%). Incidence of leptomeningeal/CNS involvement was 21%. At eMM relapse, bone marrow infiltration was absent in 46% and low in 21%. Ten eMM biopsies were available showing increased proliferation, i.e., Ki-67 of 67%(range, 30–90%) of all cancer cells. Pts received radiation therapy, dose-intense chemotherapy, novel agents, and allogeneic SCT resulting in an overall response rate of 54%. Median progression-free survival was 2 (95% CI 0.08–3.92) and median overall survival 7 months (95% CI 3.56–10.43), respectively,with only three patients being alive at 12 months from diagnosis. EMM relapse may present at any anatomical site with frequent CNS involvement. Biological features include increased proliferation and low rate of marrow involvement.Prognosis remains poor despite intensive treatment. 相似文献

Daratumumab, bortezomib and dexamethasone (DVd) is approved for patients with relapsed multiple myeloma following the CASTOR phase 3 clinical trial. This retrospective multicentre analysis assesses the overall response rate (ORR) and progression-free survival (PFS) in routine clinical practice for patients at first relapse treated with DVd incorporating weekly bortezomib. Data were collected from 296 sequential patients treated across 15 UK centres. After a median follow-up of 21 months, the ORR was 82% (26% partial response, 56% very good partial response or better) and the median PFS was 16 months [95% confidence interval (CI) 12–20 months]. Results were similar regardless of prior lenalidomide exposure. The median time to next treatment was 20 months (95% CI 15–25 months) and the estimated overall survival at two years was 74%. Patients with high-risk features (by cytogenetics, International Staging System or extramedullary disease) and those treated within 18 months of initiation of progression-free treatment, or within 12 months of autologous stem cell transplant, had significantly inferior outcomes. The grade 2 and 3 peripheral neuropathy rate was 7%. DVd with weekly bortezomib was effective in a heterogenous real-world population at first relapse with a low rate of peripheral neuropathy. However, high-risk patients had inferior outcomes and should be considered for alternative treatments. 相似文献

We investigated treatment outcomes of radiotherapy for solitary plasmacytoma (SP) and prognostic factors affecting survival. Between 1996 and 2010, a total of 38 patients were treated with radiotherapy for histologically proven plasmacytoma without evidence of multiple myeloma. Among these, 16 and 22 patients had SP originating from extramedullary soft tissue (EMP) and bone, respectively. Thirteen patients received adjuvant chemotherapy, and three patients underwent surgery prior to radiotherapy. At a median follow-up of 50?months (range, 8–142), radiotherapy demonstrated excellent local control (5- and 10-year local control rates, 81?%). However, the 10-year multiple myeloma-free survival (MMFS) was 54?% and the 10-year overall survival (OS) rates was 35?%. Solitary bone plasmacytoma (SBP) more frequently progressed to multiple myeloma (MM) than EMP (10-year MMFS, 0?% vs. 71?%, p?=?0.02). Radiotherapy with doses ≥40?Gy demonstrated better local control (10-year LC, 100?% vs. 60?%, p?=?0.04) in SBP. In the multivariate analysis, elevated β2-microglobulin was a significantly unfavorable prognostic factor affecting OS (p?=?0.03). In conclusion, radiotherapy effectively treated SP without significant toxicity. However, progression to MM presents a challenging problem. Novel therapeutics are needed for patients with unfavorable prognostic factors. 相似文献

Extramedullary disease (EMD) in multiple myeloma (MM) is characterised by an aggressive biology and an adverse prognosis especially when occurring at relapse. Due to the high proliferation found in EMD lesions, we analysed outcome data of patients treated with a lymphoma-type therapy not based on novel compounds, the Dexa-BEAM protocol. Retrospective analysis of MM patients having received Dexa-BEAM (including dexamethasone, carmustine, cytarabine, etoposide and melphalan) at our institution from January 2007 to November 2012. In all, 18 patients were identified, 11 of whom had EMD. Objective response (≥PR) to Dexa-BEAM was achieved in more than half of the patients with EMD (6/11); consecutive high-dose consolidation strategy with autologous or allogeneic stem cell transplantation improved upon the depth of remission in two thirds of EMD patients (4/6) with ongoing remissions in three patients. In contrast, all patients without consolidation relapsed. Progression-free survival after Dexa-BEAM was short in both patient groups with intramedullary or extramedullary myeloma with a median of 3 and 4 months, respectively. Toxicity was relevant with one treatment-related death and grades 3 and 4 toxicities in all 18 patients. Dexa-BEAM is an effective induction regimen in medically fit patients with extramedullary manifestations to regain disease control prior to an intended autologous or allogeneic transplantation. 相似文献

Extramedullary disease (EMD), defined as an infiltrate of clonal plasma cells at an anatomic site distant from the bone marrow, is an uncommon manifestation of multiple myeloma. Six hundred and sixty‐three consecutive patients with multiple myeloma who underwent stem cell transplantation between January 2005 and December 2011 were assessed for the presence of EMD. A cohort of 55 patients with biopsy‐proven EMD was identified, comprising 8·3% of the total study population. EMD was present at the time of diagnosis in 14·5% of cases and at the time of relapse in 76% of patients. The most common EMD presentations at relapse were liver involvement and pleural effusions. EMD specimens had high expression of CD44 (92%) and moderate expression of CXCR4. The median overall survival from time of myeloma diagnosis was 4·1 years (95% CI: 3·1, 5·1) and the median overall survival from time of EMD diagnosis was 1·3 years (95% CI: 0·8, 2·3). This report demonstrates that the incidence of EMD has not increased with the introduction of novel agents and stem cell transplantation. The most common EMD presentations in the relapsed setting were liver and pleural fluid. The presence of CD44 and CXCR4 expression may represent new markers of EMD that warrant further investigation. 相似文献

BACKGROUND AND OBJECTIVES: Autologous peripheral blood stem cell (PBSC) transplantation is widely used to treat patients with multiple myeloma (MM). However, only a small fraction of patients remain free of disease in the long-term and most patients will finally relapse. The clinical presentation of relapse after transplantation is very heterogeneous and few reports have analyzed this situation. We report the clinical patterns of relapses after autologous transplantation of 280 patients with MM included in a Spanish Multicenter Registry. DESIGN AND METHODS: The medical records of 560 patients with MM transplanted in different centers in Spain, included in the Spanish Registry of Transplant in Multiple Myeloma, were reviewed. At diagnosis, 48 (8%) had stage I disease, 143 (25%) stage II and 369 (65%) stage III. The median time from diagnosis to transplantation was 13 months (4-143). The median age was 53 years (23-70). Of the 502 patients assessable for response to intensification therapy after transplantation, 241 (48%) achieved a complete response and 220 (43%) a partial response. The clinical characteristics of 280 patients (52%) who had relapsed after transplantation were retrospectively assessed during long-term post-transplantation follow-up. RESULTS: At a median follow-up of 23 months, 280(52%) patients had relapsed or progressed after transplantation. The median overall survival was 52 months (SE 8), (CI 95% 37-68) and median estimated progression-free survival was 33 months (SE 2.2, CI 95% 27-38). The median period for relapse was 30 months (2-84) with an actuarial risk of progression or relapse at 60 months after transplantation of 78%. The clinical patterns of relapse were very heterogeneous: 40 cases (14%) presented extramedullary manifestations with multiple plasmacytomas as the main symptoms of relapse, with a minimum or null monoclonal component (MC). In 51 cases (18%) only an insidious increase of MC protein in serum or urine was detected without other clinical manifestations. In 6 cases (2%) the relapse had criteria of plasmacytic leukemia. The remaining patients presented progressive increase of MC associated with plasmacytic bone marrow infiltration and different clinical myeloma symptoms, mainly new osteolytic lesions. The therapeutic approach was also very heterogeneous, with a global antitumoral response of 30%. Median overall survival after relapse was 14 months (SE 1.4) (CI 95% 11-17). INTERPRETATION AND CONCLUSIONS: The patterns of relapse of MM after high-dose therapy are very heterogeneous. The different clinical expressions of relapse may be due to clonal selection after high-dose therapy and could indicate the persistence of a resistant clone. Some patients relapse with extraosseous plasmacytomas without systemic disease. These findings suggest the need for an individualized approach during clinical follow-up after transplantation. Regarding treatment response, patients with myeloma who relapse after high-dose chemotherapy have been classically considered to have few therapeutic options. However, we observed that after different lines of treatment, at least one-third of patients responded, with a median overall survival, after relapse of 14 months. New drugs, such as thalidomide, have been recently proved to be effective in MM patients and could increase the response rate and survival of these patients. 相似文献

The phase III MMY-3021 study compared safety and efficacy of subcutaneous versus
intravenous administration of the proteasome inhibitor bortezomib in patients with relapsed myeloma.
The initial report demonstrated non-inferior efficacy with subcutaneous versus
intravenous bortezomib for the primary end point: overall response rate after four cycles of
single-agent bortezomib. We report updated outcome analyses after prolonged follow up. Best response
rate (after up to ten cycles of bortezomib ± dexamethasone) remained 52% in each
arm, including 23% and 22% complete or near-complete responses with subcutaneous and
intravenous bortezomib, respectively. Time to progression (median 9.7 vs. 9.6
months; hazard ratio 0.872, P=0.462), progression-free survival (median 9.3
vs. 8.4 months; hazard ratio 0.846, P=0.319), and overall
survival (1-year: 76.4% vs. 78.0%,
P=0.788) were comparable with subcutaneous versus

The aim of this study was to evaluate the effectiveness of autologous stem cell transplantation for patients with relapsed or primary chemotherapy-refractory myeloma. Seventy-five patients, 50 men and 25 women, ages 33-68 years (median, 53 years), who underwent transplantation for relapsed or primary refractory myeloma were studied. Patients underwent transplantation 5-88 months (median, 23 months) after diagnosis of myeloma. The time to transplantation was significantly shorter in patients with refractory disease than for those with relapsed myeloma (median, 8 and 32 months, respectively; P < 0.001). Patients with primary refractory myeloma had a significantly lower plasma cell labeling index than those with relapsed disease (P = 0.008). There were no differences in overall and complete response rates between patients with primary refractory and relapsed disease. The median survival of the entire cohort from diagnosis was 53 months. Overall survival from transplantation among patients with relapsed myeloma receiving therapy, relapsed myeloma off therapy, and primary refractory myeloma was significantly different (P = 0.04), with median times of 12, 21 and 30 months, respectively. Progression-free survival also was different (P < 0.001), with median times of 7, 13, and 26 months, respectively. We conclude that overall and progression-free survival in patients with primary refractory myeloma appear better than in patients with relapsed disease and need further study. 相似文献

Core binding factor acute myeloid leukemia is known to have a favorable prognosis, however, there have been no detailed analyses on prognostic factors after first relapse. Using a nationwide database, we retrospectively analyzed core binding factor acute myeloid leukemia patients who relapsed after being treated with chemotherapy alone during their first complete remission. Of a total of 397 patients who were diagnosed with core binding factor acute myeloid leukemia, 208 experienced a first relapse, and analyses were performed in 139 patients for whom additional data were available. In the entire cohort, the overall survival rate after relapse was 48% at 3 years. By multivariate analysis, younger age at diagnosis, a longer interval before relapse, and inv(16) were shown to be independently associated with better survival after relapse. Although there was no significant difference in survival after relapse between patients who underwent allogeneic hematopoietic cell transplantation and those who did not in the overall series of relapsed patients, we found that transplantation significantly improved survival among patients who had t(8;21) (54% versus 26% at 3 years, P=0.002). In addition, among patients with t(8;21), those who had different cytogenetics at relapse had a significantly improved survival after transplantation, while those who had same cytogenetics did not. We showed that the prognosis differs significantly and optimal treatment strategies may vary between groups of patients with core binding factor acute myeloid leukemia with different cytogenetic profiles at relapse. These findings may help to guide therapeutic decisions after first relapse. 相似文献
