  • Article: Clinical effect of reduced-intensity conditioning regimen containing antithymocyte globulin for hematopoietic cell transplantation from unrelated-donors.
    [show abstract] [hide abstract]
    ABSTRACT: The impact of reduced-intensity conditioning (RIC) on the outcomes of hematopoietic cell transplantation (HCT) from unrelated -donors (UD) remains to be determined. We therefore assessed 128 patients, aged 16 to 66 years, with acute leukemia (n = 105) or myelodysplastic syndrome (n = 23) in a UD-HCT trial using RIC with busulfan, fludarabine, and antithymocyte globulin. Patients were transplanted with unmanipulated bone marrow (BM, n = 41) or mobilized peripheral blood mononuclear cells (M-PB, n = 87) and received cyclosporine and methotrexate for graft-versus-host disease (GVHD) prophylaxis. After a median follow-up of 26.7 months (range, 5.9-70.7 months) in surviving patients, 19 patients had died without progression/recurrence of underlying disease, giving a cumulative incidence of transplantation-related mortality (TRM) of 17% (95% confidence interval, 11%-27%; 1-year TRM, 14%). Graft failure (n = 7) and infections (n = 5) were the most common causes of TRM. Only three patients died due to GVHD (acute, one; chronic, two). Graft failure, which occurred in eight patients, showed a significant correlation with graft source (BM, 6/41 vs. M-PB, 2/87; P = 0.009). Donor-patient HLA-disparity did not correlate with GVHD, 1-year TRM, and graft failure. RIC containing antithymocyte globulin led to decreased GVHD-associated, as well as overall, TRM after UD-HCT.

  • Article: Re-analysis of the outcomes of post-remission therapy for acute myeloid leukemia with core binding factor according to years of patient enrollment.
    [show abstract] [hide abstract]
    ABSTRACT: The purpose of this study was to re-evaluate post-remission therapy outcomes after first remission according to years of patient enrollment in patients with core binding factor acute myeloid leukaemia. We conducted a retrospective study on 138 patients aged less than 60 years diagnosed with core binding factor acute myeloid leukaemia between 1994 and 2006, comparing allogeneic stem cell transplantation and high-dose cytarabine chemotherapy as post-remission treatment options after the first remission. The 5-year probabilities of disease-free survival and overall survival were not different between allogeneic stem cell transplantation and high-dose cytarabine groups. However, 3-year probabilities of disease-free survival (86.7% vs. 67.0%) and overall survival (90.0% vs. 67.3%) showed a trend towards improvement in the allogeneic stem cell transplantation group compared with the high-dose cytarabine group in cohort after 2003 (2003-2006), whereas outcomes were not different in cohort before 2003 (1994-2002). Especially, 3-year probabilities of disease-free survival (95.2% vs. 59.3%, P = 0.008) and overall survival (95.2% vs. 59.6%, P = 0.032) of allogeneic stem cell transplantation group were significantly better than high-dose cytarabine group in cohort after 2003 of acute myeloid leukaemia patients with t(8;21). The relative risk of overall survival with allogeneic stem cell transplantation, compared with high-dose cytarabine chemotherapy, was significantly improved in the cohort after 2003 (0.33; 95% CI, 0.07-1.48) when compared with that before 2003 (1.92; 95% CI, 0.77-4.82). In multivariate analysis in cohort after 2003, allogeneic stem cell transplantation as post-remission therapy was associated with better disease-free survival. Allogeneic stem cell transplantation is currently the more effective post-remission therapy than it was prior to 2003 for core binding factor acute myeloid leukaemia achieving first remission. On the contrary to previous findings, allogeneic stem cell transplantation provides significantly improved outcomes than high-dose cytarabine chemotherapy in acute myeloid leukaemia with t(8;21).

  • Article: C3435T polymorphism of the MDR1 gene is not associated with P-glycoprotein function of leukemic blasts and clinical outcome in patients with acute myeloid leukemia.
    [show abstract] [hide abstract]
    ABSTRACT: We investigated the association between the MDR1 C3435T polymorphism and P-glycoprotein function of leukemic blasts as well as clinical outcomes in 200 patients with AML, excluding the M3 subtype. The CC, CT and TT genotype frequencies of the C3435T polymorphism among patients were 71, 93 and 36, respectively. The C3435T polymorphism genotypes did not have influence on the P-glycoprotein function of leukemic blasts. Complete remission rates and overall, relapse-free and event-free survival rates were not significantly different among the C3435T polymorphism genotypes. In conclusion, the MDR1 C3435T polymorphism does not appear to have significant clinical implications in AML.

  • Article: Randomized comparison of four-times-daily versus once-daily intravenous busulfan in conditioning therapy for hematopoietic cell transplantation.
    [show abstract] [hide abstract]
    ABSTRACT: Sixty patients were randomized to receive intravenous busulfan (iBU) either as 0.8 mg/kg, over 2 hours 4 times a day (BU4 arm) or 3.2 mg/kg, over 3 hours once a day (BU1 arm) in conditioning therapy for hematopoietic cell transplantation. The complete pharmacokinetic parameters for the first busulfan dose were obtained from all patients and were comparable between the 2 arms: for the BU4 and BU1 groups, elimination half-life (mean+/-SD) was 2.75+/-0.22 versus 2.83+/-0.21 hours, estimated daily AUC was 6058.0+/-1091.9 versus 6475.5+/-1099.4 microM.min per day, and clearance was 2.05+/-0.36 versus 1.91+/-0.31 mL/min/kg, respectively. Times to engraftment after transplantation were similar between the 2 arms. No significant differences were evident in the occurrence of acute graft-versus-host disease (aGVHD) and hepatic veno-occlusion disease (VOD). Moreover, other toxicities observed within 100 days after transplantation were not significantly different between the 2 arms. The cumulative incidence of nonrelapse mortality was 20.8% in BU4 arm and 13.3% in BU1 arm. In conclusion, our randomized study demonstrates that the pharmacokinetic profiles and posttransplant complications are similar for once-daily iBU and traditional 4-times-daily iBU.

  • Article: Relationship between in vitro chemosensitivity assessed with MTT assay and clinical outcomes in 103 patients with acute leukemia.
    [show abstract] [hide abstract]
    ABSTRACT: Cellular drug resistance is supposed to play a major role in chemotherapy failure or relapse. The purpose of this study was to analyze the relationship between in vitro chemosensitivity test results using a 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and clinical response on chemotherapy, and to find the possibility of optimizing the treatment protocol for individual patients according to their actual drug resistance. For MTT assay, we obtained bone marrow aspirates from 103 patients with acute leukemia at the time of initial diagnosis or relapse. The following drugs were tested: cytarabine, vincristine, methotrexate, daunorubicin, dexamethasone, L-asparaginase, and mitoxantrone. To evaluate clinical responses after induction chemotherapy, we followed up on their bone marrow study. In our study, in vitro chemosensitivity test with the MTT assay significantly predicted whether patients with AML remained continuous complete remission or went into relapse. It also predicted whether or not child patients with ALL would acquire complete remission after induction chemotherapy. Although it does not provide the insight into the mechanisms that cause drug resistance, the MTT assay may be a useful tool in individually optimizing the chemotherapy of patients with acute leukemia.

    Article: Nonleukemic granulocytic sarcoma in the bile duct: a case report.
    [show abstract] [hide abstract]
    ABSTRACT: Granulocytic sarcoma (GS) is an extramedullary tumor composed of immature myeloid cells, typically occurring during the course of acute myelogenous leukemia. Non-leukemic GS, that is, GS with no evidence of overt leukemia and no previous history of leukemia, is very rare, and even more unusual is nonleukemic GS of the bile duct. We report a case of nonleukemic GS of the bile duct. The patient was initially misdiagnosed as a bile duct carcinoma arising in the hilum of the liver (so-called Klatskin tumor), and received a right lobectomy of the liver. Histological examination of the tumor yielded the diagnosis of GS, and the bone marrow biopsy did not show any evidence of leukemia. Considering the risk of subsequent development of overt leukemia, the patient was treated with two cycles of combination chemotherapy as used in the cases of acute myelogenous leukemia. To date, he has remained free of disease 15 months after treatment.

  • Article: Standard induction chemotherapy followed by attenuated consolidation in elderly patients with acute myeloid leukemia.
    [show abstract] [hide abstract]
    ABSTRACT: The benefits of intensive post-remission chemotherapy have not been verified in elderly patients with acute myeloid leukemia (AML). To reduce fatal complications caused by intensive post-remission therapy, we performed a prospective phase II multicenter trial of standard induction chemotherapy ('7+3' of cytarabine plus daunorubicin), followed by two cycles of attenuated consolidation therapy ('5+1' of cytarabine plus daunorubicin) for elderly patients with AML, excluding those with M3. Of the 41 patients enrolled in the study, 24 (58.5%) attained CR. Of these 24, 17 (70.8%) completed both planned cycles of consolidation therapy. After a median follow-up of 566 days (range, 63-1190 days) among surviving patients, 15 relapsed, with an actuarial 3-year disease-free survival rate of 22.5%. There were no fatal complications during consolidation therapy. Actuarial 3-year overall survival was 17.0%. These findings suggest that, when compared with previous findings using more intensive consolidation therapy, attenuated consolidation therapy does not compromise outcomes in elderly AML patients.

  • Article: Continuous infusion intermediate-dose cytarabine, mitoxantrone, plus etoposide for refractory or early relapsed acute myelogenous leukemia.
    [show abstract] [hide abstract]
    ABSTRACT: For refractory and early relapsed AML, this prospective phase II clinical trial evaluated a salvage chemotherapy regimen, which was consisted of continuous infusion intermediate-dose cytarabine (1g/m(2)/day, 24h i.v. infusion x 5), mitoxantrone (12 mg/m(2)/day x 3), and etoposide (150 mg/m(2)/day x 3). We treated 33 patients and 17 (51.5%) achieved CR with a median duration of 117 days. Median overall survival was 219 days. Our results suggest that continuous infusion intermediate-dose cytarabine, together with mitoxantrone and etoposide, may induce CR in a significant proportion of patients with refractory or early relapsed AML, although remission duration was short.

  • Article: Anti-leukemic effect of graft-versus-host disease on bone marrow and extramedullary relapses in acute leukemia.
    [show abstract] [hide abstract]
    ABSTRACT: Several reports have suggested that the graft-versus-leukemia effect at extramedullary (EM) sites might be less prominent than that in the bone marrow (BM). We analyzed the effect of graft-versus-host disease (GVHD) on BM and EM relapses in 194 consecutive patients with acute leukemia who underwent allogeneic hematopoietic cell transplantation at a single institute. We compared relapse-free survival (RFS), BM RFS, and EM RFS after allografting according to the occurrence of GVHD. We also investigated the clinical outcome of patients who relapsed after their allogeneic transplantation. Relapse occurred in 65 patients; in 41 (63%) relapse occurred in the BM only, in 9 (14%) it occurred in both BM and EM sites, and 15 (23%) in EM sites only. Patients who developed acute GVHD after transplantation had significantly higher relapse-free survival (69.2% vs. 52.4%; p=0.042) and BM RFS (80.7% vs. 59.1%; p=0.030) compared to those who did not. However, EM RFS was similar between patients with and without acute GVHD (76.7% vs. 78.2%; p=0.744). Among the 65 patients who relapsed, 32 patients attained complete remission with salvage treatments and 22 experienced a second relapse, which occurred in the BM (n=9), BM and EM sites (n=1), or EM sites (n=12). Our study confirms that GVHD after allogeneic hematopoietic cell transplantation has an anti-leukemic effect, thus preventing relapse; however, it may be less effective in preventing EM relapse.

  • Article: Prognostic factors identifiable at the time of onset of acute graft-versus-host disease after allogeneic hematopoietic cell transplantation.
    [show abstract] [hide abstract]
    ABSTRACT: Current grading systems of acute graft-versus-host disease (GVHD) cannot effectively identify patients with poor prognosis at the onset of acute GVHD after allogeneic hematopoietic cell transplantation. In a retrospective analysis, we evaluated the prognostic value of various clinical parameters at the initiation of treatment in 83 patients who developed systemic treatment-requiring acute GVHD after allogeneic hematopoietic cell transplantation. Forty-three of 83 patients (52%) experienced initial treatment failure (40 required secondary treatment due to lack of response and 3 died) and 43 (52%) experienced treatment success, defined as completion of treatment (initial and, if given, secondary) within 100 days. The GVHD-specific survival rate was 65.5%, with 27 deaths due to GVHD-related complications without relapse of underlying malignancies within 1 year. HLA-mismatched transplantation, visceral initiation, and peripheral blood lymphocytopenia ( pound100/mL) were independent variables predicting higher initial treatment failure (Odd ratios (OR)=12.225, 12.036, and 7.481, respectively). The above variables and initial acute GVHD grade III-IV vs. II were independent variables predicting shorter GVHD-specific survival (OR=0.322, 0.247, 0.340, and 0.385, respectively). High-risk disease status, visceral initiation, and hypoalbuminemia ( pound2.8 g/dL) were independent variables predicting lower treatment success (OR=0.221, 0.162, and 0.270, respectively). The predictive value of visceral initiation and lymphocytopenia for GVHD-specific survival was verified in an independent cohort of 58 patients. Lymphocytopenia and hypoalbuminemia may be useful baseline prognostic factors for acute GVHD after allogeneic hematopoietic cell transplantation.

  • Article: Decreased incidence of hepatic veno-occlusive disease and fewer hemostatic derangements associated with intravenous busulfan vs oral busulfan in adults conditioned with busulfan + cyclophosphamide for allogeneic bone marrow transplantation.
    [show abstract] [hide abstract]
    ABSTRACT: We investigated the occurrence of hepatic veno-occlusive disease (VOD) after allogeneic bone marrow transplantation (BMT) in 241 adults conditioned with busulfan + cyclophosphamide at a single institute and retrospectively compared 186 patients who received oral busulfan (O-Bu group) with 55 patients who received intravenous busulfan (I-Bu group). Various hemostatic parameters were determined at baseline and on days 0, 7, 14, and 21. Hepatic VOD occurred in 41.7% of the O-Bu group and in 18.5% of the I-Bu group. Multivariate analysis revealed that the I-Bu group had significantly decreased risk of VOD compared to the O-Bu group [p=0.006, odds ratio: (OR) 0.345]. Eleven patients in the O-Bu group and none of the I-Bu group developed severe VOD. A repeated measures analysis of variance (ANOVA) with a between-subjects factor revealed significant differences in post-transplant levels of antithrombin III, tissue plasminogen activator (tPA), plasminogen activator inhibitor 1 (PAI-1), and D-dimer according to the occurrence of VOD. The level of antithrombin III was significantly lower, whereas the level of D-dimer was significantly higher, in the O-Bu group than in the I-Bu group. These findings show that, in adults conditioned with busulfan + cyclophosphamide, intravenous busulfan was associated with significantly decreased incidence of VOD and fewer hemostatic derangements after allogeneic BMT compared to oral busulfan.

  • Article: Phase II study of paclitaxel and carboplatin in advanced gastric cancer previously treated with 5-fluorouracil and platinum.
    [show abstract] [hide abstract]
    ABSTRACT: The combination of paclitaxel and carboplatin has been used to treat patients with many types of tumor, including gastric cancer. We evaluated the efficacy and safety of this combination in advanced gastric cancer patients previously treated with 5-fluorouracil and platinum. Patients who had pathologically been proven to have measurable lesions were treated with paclitaxel (200 mg/m(2) for 3 h) and carboplatin [area under the concentration-time curve (AUC = 6)] on day 1 and in 21 day cycles. A partial response was achieved in 10 of 45 patients [22%, 95% confidence interval (CI), 10-34]. Of the 32 patients previously treated with cisplatin, four (13%) achieved partial response, whereas, of the 13 patients previously treated with heptaplatin, six (46%) achieved partial response. In all patients, the median time to progression was 14 weeks (95% CI, 10-18), and the median overall survival was 32 weeks (95% CI, 26-38). The most common grade 3/4 adverse events were neutropenia (40% of patients) and neuropathy (2.2%). Two patients developed neutropenic fever. However, there were no treatment-related deaths. Combination chemotherapy with paclitaxel and carboplatin is feasible in patients with advanced gastric cancer who were previously treated with 5-fluorouracil and platinum.

  • Article: Infused CD34+ cell dose predicts long-term survival in acute myelogenous leukemia patients who received allogeneic bone marrow transplantation from matched sibling donors in first complete remission.
    [show abstract] [hide abstract]
    ABSTRACT: Allogeneic stem cell transplantation (ASCT) has improved the outcome of acute myelogenous leukemia (AML). To further improve the treatment outcome of ASCT in AML, finding a modifiable prognostic factor is mandatory. We evaluated the effect of CD34(+) cell dose on survival in allogeneic bone marrow transplantation (BMT) from HLA-matched sibling donors for AML patients in first complete remission (CR1). The 99 patients included in our analysis were classified into high CD34(+) cell dose group (CD34(+) cells > or = 2.5 x 10(6)/kg) and low CD34(+) cell dose group (CD34(+) cells < 2.5 x 10(6)/kg). The high CD34(+) cell dose patients had better overall survival (5-year overall survival rate, 75% +/- 6% vs 52% +/- 9%; P = .01) and leukemia-free survival (5-year leukemia-free survival rate, 70% +/- 6% vs 44% +/- 9%; P = .04). CD34(+) cell dose was the only independent prognostic factor in overall survival and leukemia-free survival. The high CD34(+) cell dose group had a lower relapse incidence with a borderline statistical significance (5-year relapse rate, 27% +/- 6% vs 50% +/- 10%; P = .09). There were no differences in the engraftment of neutrophil and platelet, grade II-IV acute graft-versus-host disease (GVHD), extensive-stage chronic GVHD, and transplant-related mortality between the high and low CD34(+) cell dose groups. We confirmed that high CD34(+) cell dose favorably affects the outcomes in allogeneic BMT for AML. The effort to attain a high CD34(+) cell dose should be pursued during bone marrow harvest in allogeneic BMT for AML in CR1.

  • Article: Retrospective multicenter study of allogeneic peripheral blood stem cell transplantation followed by reduced-intensity conditioning or conventional myeloablative regimen.
    [show abstract] [hide abstract]
    ABSTRACT: This retrospective study compared the results of reduced-intensity conditioning stem cell transplantation (RIST) and a conventional myeloablative regimen (CST) followed by allogeneic peripheral blood stem cell transplantation. In this respect, 63 RISTs and 41 CSTs were performed at 5 transplantation centers in Korea between April 1998 and December 2002. The RIST group had more adverse pretransplant characteristics. More aggressive diseases, like acute myeloid or lymphoblastic leukemia, were included in the CST group, while the RIST group included more indolent diseases, like chronic myeloid leukemia or myeloma (p < 0.001). The incidence of acute graft-versus-host disease (GVHD) grades 2-4 was 29.1 and 57.9% for the RIST and CST groups, respectively (p = 0.010), yet the incidence of chronic GVHD was similar in the two groups (57.4 vs. 71.9%). With a median follow-up of 13 months (0.5-61 months, 17 months in 52 survivors), the 3-year overall (OS) and disease-free survival (DFS) was similar in the RIST and CST groups (p = 0.965 for OS, p = 0.545 for DFS). In a multivariate analysis, RIST (p = 0.010), good performance status (p = 0.006) and a higher CD34+ cell dose (p = 0.008) were all identified as independent favorable prognostic factors for OS. Accordingly, in the current study, RIST produced equivalent or acceptable results compared with CST in terms of OS. Therefore, a prospective randomized trial of RIST and CST is warranted.

  • Article: A phase II study of paclitaxel plus cisplatin chemotherapy in an unfavourable group of patients with cancer of unknown primary site.
    [show abstract] [hide abstract]
    ABSTRACT: We evaluated the efficacy and toxicity of combined paclitaxel and cisplatin chemotherapy in patients with cancer of unknown primary site (CUP). Efficacy was evaluated in terms of response rate, progression-free survival and overall survival. Thirty-seven patients with CUP were enrolled between January 2001 and September 2003 at Korea Cancer Center Hospital. The patients received 21-day cycles of paclitaxel (175 mg/m(2) i.v.) with cisplatin (60 mg/m(2) i.v.) given on the first day. Of the 37 patients, 31 had adenocarcinoma subtypes. The overall response rate of 26 patients with measurable lesions was 42% [95% confidence interval (CI) 23-61%]. Stable disease was seen in six patients and progressive disease in nine. Median time to progression was 4 months (95% CI 1.3-6.8). Median overall survival was 11 months (95% CI 8.3-13.5). The major toxicities were neuropathy and neutropenia. Grade 4 neutropenia occurred in 10 patients, but febrile neutropenia was seen in four. This combined paclitaxel and cisplatin regimen was well tolerated with an encouraging level of effectiveness for patients with CUP.

    ABSTRACT: We analyzed the clinical significance of the expression of the Fas (CD95) and TNF-related apoptosis-inducing ligand (TRAIL) receptors, the death receptors (DR) 4 and 5, by leukemic blasts in 29 patients with acute myelogenous leukemia (AML). CD95 was positive in 18 patients (62%). The DR4 and DR5 receptors were positive in 20 patients (69%) and 29 (100%), respectively. CD95 positivity was not correlated with cytogenetic abnormalities. Complete remission (CR) rate was not significantly different according to the expression of the CD95 or TRAIL receptors. Relapse-free survival was significantly prolonged in patients with CD95-positive AML cells compared with patients with CD95-negative AML cells (73% versus 38% at 3 years; P = 0.047). TRAIL receptors did not show correlation with other clinical parameters.

    Article: The risk of cytomegalovirus infection in non-myeloablative peripheral stem cell transplantation compared with conventional bone marrow transplantation.
    [show abstract] [hide abstract]
    ABSTRACT: Non-myeloablative allogeneic peripheral stem cell transplantation (NST) is a novel therapeutic strategy for patients with hematologic malignancies. Whether non-myeloablative transplants are associated with increased risk of cytomegalovirus (CMV) infections is unknown. To clarify this issue, we compared the outcome of CMV infection following 24 allogeneic non-myeloablative peripheral blood stem cell transplants and 40 conventional bone marrow transplants (CBT). The NST regimen consisted (mg/kg). Twelve patients (50%) in the NST group and 17 (43%) in the CBT group developed positive antigenemia before day 100 (p=0.60). The time to the first appearance of positive antigenemia was not different between these two groups (p=0.40), and two groups showed similar initial and maximal antigenemia values (p=0.56 and p=0.68, respectively). Only one case of CMV colitis developed in the CBT group whereas CMV disease did not develop in the NST group. Although statistically insignificant, the treatment response against CMV antigenemia using ganciclovir was in favor of NST group. In conclusion, there was no difference in the risk of CMV infection between NST group and CBT group. Further prospective and controlled study is needed to clarify the impact of non-myeloablative procedure on the outcome of CMV infection.
