Article: Comparative analysis between azacitidine and decitabine for the treatment of myelodysplastic syndromes.
[show abstract] [hide abstract]
ABSTRACT: The present study aimed to directly compare the efficacy and safety of azacitidine and decitabine in patients with myelodysplastic syndromes (MDS). We compared the overall response rate (ORR) (complete responses, partial responses, marrow complete responses, and haematological improvements), overall survival (OS), event-free survival (EFS), time to leukaemic transformation, and adverse outcomes between azacitidine and decitabine. To minimize the effects of treatment selection bias in this observational study, adjustments were made using the propensity-score matching method. Among 300 patients, 203 were treated with azacitidine and 97 with decitabine. Propensity-score matching yielded 97 patient pairs. In the propensity-matched cohort, there were no significant differences between the azacitidine and decitabine groups regarding ORR (44% vs. 52%), OS (26 vs. 22·9 months), EFS (7·7 vs. 7·0 months), and rate of leukaemic transformation (16% vs. 22% at 1 year). In patients ≥65 years of age, survival was significantly better in the azacitidine group (P = 0·017). Patients who received decitabine experienced more frequent episodes of grade 3 or 4 cytopenia and infectious episodes. We found that azacitidine and decitabine showed comparable efficacy. Among patients ≥65 years of age, survival was significantly better in the azacitidine group (ClinicalTrials.gov Identifier: NCT01409070).British Journal of Haematology 02/2013; · 4.94 Impact Factor -
Article: Sudden atelectasis and respiratory failure in a neutropenic patient: atypical presentation of pseudomembranous necrotizing bronchial aspergillosis.
[show abstract] [hide abstract]
ABSTRACT: Pseudomembranous necrotizing bronchial aspergillosis (PNBA) is a rare form of invasive aspergillosis with a very poor prognosis. The symptoms are non-specific, and the necrotizing plugs cause airway obstruction. Atelectasis and respiratory failure can be the initial manifestations. Recently, we treated an immunocompromised patient with PNBA, who presented with a sudden onset of atelectasis and acute respiratory failure. There were no preceding signs except for a mild cough and one febrile episode. Bronchoscopy revealed PNBA, and Aspergillus nidulans was cultured from the bronchial wash.The Korean Journal of Internal Medicine 12/2012; 27(4):463-6. -

Article: Isolation of Side Population Cells in B-Cell Non-Hodgkin's Lymphomas.
[show abstract] [hide abstract]
ABSTRACT: Background: Side population (SP) cells are characterized by the ability to exclude Hoechst 33342 dye due to high expression of the ATP-binding cassette transporter. This ability is associated with drug-resistant characteristics of cancer stem cells. Methods: We analyzed SP cells from human B-cell non-Hodgkin's lymphoma cell lines and primary cells derived from patients and compared them with non-SP (NSP) cells. Results: SP cells comprised a minor fraction of all cells ranging from 1.5 ± 1.8 to 8.3 ± 5.7% in cell lines and had higher ABCG2 expression than NSP cells. SP cells had better cell viability, colony-forming ability and drug resistance than NSP cells. The SP cells also showed stem cell-like characteristics, including elevated telomerase activity and higher expression of OCT4 and NANOG. A cDNA microarray demonstrated that SP cells had decreased expression of genes associated with apoptosis and cell death compared to NSP cells. Conclusions: The presence of SP cells might imply the possibility of lymphoma stem cells and be associated with a malignant potential of B-cell lymphoma.Acta Haematologica 09/2012; 129(1):10-17. · 1.35 Impact Factor -
Article: Extranodal natural killer/T-cell lymphoma with long-term survival and repeated relapses: does it indicate the presence of indolent subtype?
[show abstract] [hide abstract]
ABSTRACT: Extranodal natural killer (NK)/T-cell lymphoma is a subtype of lymphoma that is derived from NK cells. It is considered as an aggressive form of non-Hodgkin's lymphoma because of frequent relapses and resistance to treatment. Relapsed NK/T-cell lymphoma often follows a fulminant course that is refractory to conventional chemotherapy treatment. Several patients with extranodal NK/T-cell lymphoma showed long-term survival in spite of frequent relapses. Thus, the medical records of patients diagnosed with extranodal NK/T-cell lymphoma from 1995 to 2007 were reviewed and assessed. Of the 140 cases reviewed, 6 were selected (4.29%). Each of these patients had a minimum of 3 relapses or disease progression during the follow-up period, and their median overall survival was 66 months (range, 42-89 months). They were grouped according to the atypical clinical behavior observed: (1) repeated relapses or progression (≥3 times) during follow-up; and (2) long-term survival of more than 40 months, as the longest overall survival median was previously considered at approximately 40 months. The clinicopathological and laboratory characteristics of these patients were similar to those of other extranodal NK/T-cell lymphoma patients. However, 5 of the studied cases involved relatively lower expression of the proliferation-related antigen Ki-67 (<40-50%), indicating less proliferative activity. Clinically, they showed delayed relapse for at least 20 months after the initial complete remission. Our observations suggest that the clinical behavior of some extranodal NK/T-cell lymphoma patients differs from the typical clinical course.The Korean journal of hematology 09/2012; 47(3):202-6. -
Article: Overexpression of romo1 promotes production of reactive oxygen species and invasiveness of hepatic tumor cells.
[show abstract] [hide abstract]
ABSTRACT: Chronic oxidative stress from reactive oxygen species (ROS) produced by the mitochondria promotes hepatocarcinogenesis and tumor progression. However, the exact mechanism by which mitochondrial ROS contributes to tumor cell invasion is not known. We investigated the role of ROS modulator 1 (Romo1) in hepatocellular carcinoma (HCC) development and tumor cell invasiveness. We performed real-time, semi-quantitative, reverse transcriptase polymerase chain reaction; invasion and luciferase assays; and immunofluorescence and immunohistochemical analyses. The formation of pulmonary metastatic nodules after tumor cell injection was tested in severe combined immunodeficient mice. We analyzed Romo1 expression in HCC cell lines and tissues (n = 95). Expression of Romo1 was increased in HCC cells, compared with normal human lung fibroblast cells. Exogenous expression of Romo1 in HCC cells increased their invasive activity, compared with control cells. Knockdown of Romo1 in Hep3B and Huh-7 HCC cells reduced their invasive activity in response to stimulation with 12-O-tetradecanoylphorbol-13-acetate. Levels of Romo1 were increased compared with normal liver tissues in 63 of 95 HCC samples from patients. In HCC samples from patients, there was an inverse correlation between Romo1 overexpression and patient survival times. Increased levels of Romo1 also correlated with vascular invasion by the tumors, reduced differentiation, and larger tumor size. Romo1 is a biomarker of HCC progression that might be used in diagnosis. Reagents that inhibit activity of Romo1 and suppress mitochondrial ROS production, rather than eliminate up-regulated intracellular ROS, might be developed as cancer therapies.Gastroenterology 06/2012; 143(4):1084-1094.e7. · 11.68 Impact Factor -
Article: Successful treatment of disseminated interdigitating dendritic cell sarcoma with adriamycin, bleomycin, vinblastine, and dacarbazine chemotherapy.
[show abstract] [hide abstract]
ABSTRACT: Interdigitating dendritic cell sarcoma (IDCS) is a very rare and aggressive neoplasm that arises from antigen presenting cells. IDCS usually involves lymph nodes; however, extra-nodal involvement has also been reported. Because a consistent standard therapy for IDCS has not been established to date, we report a case of the successful treatment of disseminated IDCS using ABVD chemotherapy (doxorubicin, bleomycin, vinblastine, and dacarbazine). A 64-year-old man was diagnosed with IDCS on the basis of immunohistochemical findings of a biopsy specimen of the inferior nasal concha. Immunohistochemical staining showed a positive reaction for CD68, leukocyte common antigen, and S-100 protein, but a negative reaction for CD34, CD1a, and CD21. Imaging studies showed cervical and axillary lymphadenopathies, subcutaneous nodules, and a soft tissue lesion in the nasal cavity. Treatment with the ABVD regimen resulted in complete remission after 8 cycles of chemotherapy.The Korean journal of hematology 06/2012; 47(2):150-3. -
Article: Treatment outcomes of oxaliplatin, 5-FU, and leucovorin as salvage therapy for patients with advanced or metastatic gastric cancer: a retrospective analysis
[show abstract] [hide abstract]
ABSTRACT: PurposeWe performed a single-institution retrospective study to evaluate the efficacy and toxicities of oxaliplatin, 5-fluorouracil (5-FU), leucovorin (LV) combination chemotherapy as salvage treatment in patients with metastatic or advanced gastric cancer. MethodsSixty-two patients with advanced gastric cancer previously treated were eligible for the study. Patients received oxaliplatin 100mg/m2 and LV 100mg/m2 (2-h intravenous infusion) followed by 5-FU 2,400mg/m2 (46-h continuous infusion) every 2weeks, and responses were assessed after every three cycles. ResultsFifty-nine out of 62 patients were assessable for response. Among them, 46 patients had previously been treated with cisplatin based chemotherapy. Patients had a median age of 57years (range 32–76years), 72.6% had an Eastern Cooperative Oncology Group performance status of 0 or 1. Total 296 courses of chemotherapy were administered as second-line (67.7%) or third-line (27.4%), and the median courses per patient was three cycles. Out of 59 evaluable patients, 14 partial responses were observed (overall response rate, 22.6%). Stable disease was observed in 22 patients (35.5%), and progressive disease in 23 patients (37.1%). The median response duration, time to progression, and overall survival were 2.3, 3.0, and 8.0months, respectively. The major toxicities were neutropenia, mucositis, and peripheral neuropathy. Grade 3 or 4 hematologic toxicities included neutropenia in nine patients (14.5%) and thrombocytopenia in one patient (1.6%). Other grade 3 or 4 toxicities included mucositis in one patient (1.6%) and vomiting in two patients (3.2%). Grade 1 or 2 peripheral neuropathy were observed in 18 patients (29.0%), however there were no cases of grade 3 or 4 peripheral neuropathy and no treatment-related deaths. ConclusionThe combination of oxaliplatin, 5-FU and LV was effective and safe salvage chemotherapy in advanced gastric cancer patients.Cancer Chemotherapy and Pharmacology 04/2012; 63(3):433-439. · 2.83 Impact Factor -
Article: Extrinsic nitric oxide donor partially reverses arginine deiminase induced cell growth inhibition through NFκB and Bcl-XL
[show abstract] [hide abstract]
ABSTRACT: Arginine deiminase (ADI) is known to be an inducer of apoptosis in vitro and an anti-tumor agent in vivo in some cancers. ADI causes the enzymatic depletion of arginine which may inhibit nitric oxide (NO) synthesis. However, the effect of ADI treatment on NO synthesis has not been clearly elucidated. With the goal of understanding the role of ADI in NO synthesis, we used the Ramos human lymphoma cell line, which is known to be ADI-sensitive. After determining an optimal experimental ADI concentration (0.001U/ml), we studied the effects of ADI treatment when combined with different concentrations of the extrinsic NO donor, sodium nitroprusside (SNP) (i.e., control, ADI only, ADI with 10μM/ml SNP, ADI with 50μM/ml SNP, and ADI with 100μM/ml SNP). An MTT assay was used to assess cell survival after treatment, nitric oxide assays to determine nitrite levels and Western blot analysis to determine the expression of the NO mediators, NFκB and Bcl-X L . Interestingly, we found that the extrinsic NO donor only partially reversed ADI-induced inhibition of cell growth in a dose-dependent pattern and resulted in an induction of NFκB and Bcl-X L expression. In conclusion, we suggest that there might be an association between reversal of cell growth inhibition by extrinsic NO donor with Bcl-XL and NFκB expression in ADI-treated Ramos cell.Investigational New Drugs 04/2012; 26(3):277-282. · 3.36 Impact Factor -
Article: Long-Term Engraftment Stability of Peripheral Blood Stem Cells Cryopreserved Using the Dump-Freezing Method in a −80°C Mechanical Freezer with 10% Dimethyl Sulfoxide
[show abstract] [hide abstract]
ABSTRACT: In this study, we summarize our long-term follow-up data of 24 patients who underwent autologous peripheral blood stem cell transplantation (PBSCT) using the dump-freezing method in a −80°C freezer. Collected peripheral blood mononuclear cells were mixed with a cryoprotectant solution consisting of autologous plasma and 20% dimethyl sulfoxide, then placed in a −80°C freezer. The recovery rate of mononuclear cells (MNCs), colony-forming unit—granulocyte/macrophage (CFU-GM) colonies, and CD34+ cells were calculated. Engraftment time (with neutrophil count > 0.5 × 109/L, platelet count > 50 ×109/L) and normal hemopoiesis (neutrophil count > 2 ×109/L, platelet count > 100 ×109/L) were evaluated. Median duration of cryopreservation was 76 days. The mean recovery rates of MNCs, CFU-GM colonies, and CD34+ cells were 93.4%, 78.4%, and 95.3%, respectively. The median engraftment times of neutrophils and platelets were 8 and 27 days, respectively. The median normal hemopoiesis times of neutrophil and platelet were 31 and 45 days, respectively. Nine patients are alive and in complete remission (CR). Seven patients in first CR sustained normal hemopoiesis with a median duration of 35 months. Two patients, who achieved second CR after salvage chemotherapy due to a leukemia relapse after PBSCT, maintained engraftment status for 24 and 28 months, and 1 reached normal hemopoiesis. These results demonstrate that PBSCT using the dump-freezing method in a −80°C freezer leads to acceptable long-term engraftment stability.International Journal of Hematology 04/2012; 73(2):245-250. · 1.27 Impact Factor -
Article: Allogeneic Hematopoietic Stem Cell Transplant for Adults over 40 Years Old with Acquired Aplastic Anemia.
[show abstract] [hide abstract]
ABSTRACT: Although younger age is associated with favorable prognosis in adults undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT) for aplastic anemia (AA), other pretransplantation factors may be more important than age. We retrospectively analyzed the impact of older age on transplantation outcomes and survival in a total of 225 adult patients with AA who underwent allo-HSCT: 57 patients >40 years old (older patient group [OPG]) and 168 patients ≤40 years old (younger patient group [YPG]). Age at allo-HSCT ≤40 years, time from diagnosis to allo-HSCT ≤6 months, and matched related donor (MRD) were favorable prognostic factors in all study patients. Risk analysis of survival in the OPG showed that age >50 years was the only poor prognostic factor. Survival did not differ significantly between the YPG and patients <50 years old in the OPG. In conclusion, patients between the ages of 41 and 50 years with severe AA and MRDs should undergo allo-HSCT as early as possible to optimize survival.Biology of blood and marrow transplantation: journal of the American Society for Blood and Marrow Transplantation 03/2012; 18(10):1500-1508. · 3.15 Impact Factor -
Article: Dose modification of alemtuzumab in combination with dexamethasone, cytarabine, and cisplatin in patients with relapsed or refractory peripheral T-cell lymphoma: analysis of efficacy and toxicity.
[show abstract] [hide abstract]
ABSTRACT: There is still no consensus on the role of alemtuzumab as a salvage therapy for relapsed or refractory peripheral T-cell lymphoma (PTCL). We studied the efficacy and toxicity of combination treatment of alemtuzumab, dexamethasone, cytarabine, and cisplatin (A-DHAP) for treating PTCL. We enrolled 24 patients with relapsed or refractory PTCL. Each patient received DHAP plus alemtuzumab every 3 weeks for up to three cycles. Two alemtuzumab dosages of 70 mg or 40 mg were used per cycle. After A-DHAP treatment, the responders underwent autologous stem cell transplantation. The overall response rate was 50.0% (12 of 24 patients), including five complete responders and seven partial responders. Analysis of the responses according to histological type showed a higher objective response rate for PTCL-unspecified (69.2%: four complete responders, five partial responders) than for extranodal NK/T cell lymphoma (12.5%, one partial responder). The median overall survival (OS) after enrollment was 6.0 months (95% confidence interval: 4.20-7.80 months), and the median response duration of responders was 2.93 months (95% confidence interval: 0.93-4.93 months). The overall response rate and OS did not differ significantly according to the dosage of alemtuzumab (70 mg vs. 40 mg, P > 0.05). The most frequent side effect was grade 3/4 leukopenia. Non-disease-related death occurred more frequently in patients who received 70 mg of alemtuzumab. The combination of alemtuzumab plus DHAP might be effective salvage chemotherapy for PTCL, and 40 mg of alemtuzumab appears to be a more tolerable dosage when used in combination with DHAP.Investigational New Drugs 02/2012; 30(1):368-75. · 3.36 Impact Factor -
Article: Romo1 is a negative-feedback regulator of Myc.
[show abstract] [hide abstract]
ABSTRACT: Degradation of Myc protein is mediated by E3 ubiquitin ligases, including SCF(Fbw7) and SCF(Skp2), but much remains unknown about the mechanism of S-phase kinase-associated protein (Skp2)-mediated Myc degradation. In the present study, we show that upregulated Myc protein, which triggers the G1-S phase progression in response to growth-stimulatory signals, induces reactive oxygen species modulator 1 (Romo1) expression. Romo1 subsequently triggers Skp2-mediated ubiquitylation and degradation of Myc by a mechanism not previously reported in normal lung fibroblasts. We also show that reactive oxygen species (ROS) derived from steady-state Romo1 expression are necessary for cell cycle entry of quiescent cells. From this study, we suggest that the generation of ROS mediated by pre-existing Romo1 protein is required for Myc induction. Meanwhile, Romo1 expression induced by Myc during G1 phase stimulates Skp2-mediated Myc degradation in a negative-feedback mechanism.Journal of Cell Science 06/2011; 124(Pt 11):1911-24. · 6.11 Impact Factor -
Article: Pretreatment serum level of 15-kDa granulysin might have a prognostic value in patients with diffuse large B cell lymphoma.
[show abstract] [hide abstract]
ABSTRACT: Granulysin (cytolytic molecules of cytotoxic T lymphocytes and natural killer cells) is synthesized as cytosolic 9-kDa and secretary 15-kDa isoforms. We evaluated the prognostic significance of the pretreatment serum level of 15-kDa granulysin in patients with diffuse large B cell lymphoma (DLBCL). A retrospective analysis was conducted on 88 DLBCL patients treated homogeneously with standard chemotherapy. The granulysin level was quantified in pretreatment samples. The granulysin level in DLBCL patients was significantly lower than that in healthy controls (522 ± 496 vs. 1,945 ± 1,696 pg/ml; p < 0.0001), and the level in patients who experienced recurrence within 3 years was significantly lower than that of patients without recurrence (305 ± 337 vs. 720 ± 607 pg/ml; p = 0.001). Patients with granulysin levels higher than the median level showed significantly longer progression-free and overall survival according to univariate analysis (p = 0.031 and p = 0.014, respectively). In multivariate analysis, the granulysin level was an independently significant prognostic factor of overall survival (p = 0.018; hazard ratio, 0.521; 95% confidence interval, 0.188-0.841). Pretreatment serum level of 15-kDa granulysin may be a valuable prognostic marker in DLBCL patients treated with standard chemotherapy.Acta Haematologica 05/2011; 126(2):79-86. · 1.35 Impact Factor -
Article: Trough plasma imatinib levels are correlated with optimal cytogenetic responses at 6 months after treatment with standard dose of imatinib in newly diagnosed chronic myeloid leukemia.
[show abstract] [hide abstract]
ABSTRACT: To investigate the correlation of trough imatinib mesylate (IM) levels with cytogenetic or molecular responses, we measured trough IM levels in patients with chronic myeloid leukemia, chronic phase (CML-CP), at 6 months of treatment with a standard dose of IM. Eighty-seven newly diagnosed patients with CML-CP were prospectively enrolled. Seventy-eight patients (89.7%) showed an optimal response (complete or partial cytogenetic response) at 6 months. Trough IM levels were 1378 ± 725 ng/mL. When categorized into two groups, there was a statistically significant difference in numbers of patients with optimal and suboptimal responses at 6 months (group with <1000: 80.6% vs. 19.4%; ≥ 1000: 94.6% vs. 5.4%; p = 0.032), and in numbers of patients with early major molecular response (early-MMR) and without MMR at 6 months (group with <1000: 3.2% vs. 96.8%; ≥ 1000: 21.4% vs. 78.6%; p = 0.047). In conclusion, the incidence of optimal cytogenetic response or early-MMR in patients with CML-CP treated with IM for 6 months was significantly higher in those with a trough level of ≥ 1000 compared with those with a level of <1000. Dose escalation of IM can be one option in patients with CML showing suboptimal response or resistance to the standard dose of IM, especially with low trough plasma IM levels (<1000 ng/mL).Leukemia & lymphoma 04/2011; 52(6):1024-9. · 2.40 Impact Factor -

Article: Human feeder cells can support the undifferentiated growth of human and mouse embryonic stem cells using their own basic fibroblast growth factors.
[show abstract] [hide abstract]
ABSTRACT: In the culture system using human feeder cells, the mechanism through which these cells support undifferentiated growth of embryonic stem cells (ESCs) has not been well investigated. Here, we explored the mechanisms of 3 kinds of human feeder cells, including human placental cells from the chorionic plate, human bone marrow stromal cells, and human foreskin fibroblasts. First, we determined that undifferentiated growth of 2 kinds each of human (H1 and HSF6) and mouse (D3 and CE3) ESCs was possible in all human feeder cell types tested (human placental cells, human bone marrow stromal cells, and human foreskin fibroblasts), without the need for exogenous cytokine supplementation including basic fibroblast growth factor (bFGF) and leukemia inhibitory factor. We then prepared their corresponding endogenous bFGF-knockout feeders using siRNA and tried to maintain human and mouse ESCs in their undifferentiated state; however, neither human nor mouse ESCs could be maintained in bFGF-knockout human feeder cells. The expressions of stemness markers such as Oct-4 and Nanog were significantly decreased in the bFGF-knockout group compared with those in the controls, and differentiation had already occurred, despite the undifferentiated morphologic appearance of the ESCs. In conclusion, human feeder cells are able to support the undifferentiated growth of human and mouse ESCs via bFGF synthesis. Further, a bFGF-dependent pathway might be crucial for maintaining the undifferentiated characteristics of mouse and human ESCs.Stem cells and development 01/2011; 20(11):1901-10. · 4.15 Impact Factor -
Article: Comparison between matched related and alternative donors of allogeneic hematopoietic stem cells transplanted into adult patients with acquired aplastic anemia: multivariate and propensity score-matched analysis.
[show abstract] [hide abstract]
ABSTRACT: We retrospectively compared the outcomes of 225 patients with adult acquired aplastic anemia (AA) who underwent allogeneic hematopoietic stem cell transplantation (alloHSCT) from matched related donors (MRDs), and those treated by alloHSCT from alternative donors (ADs). Univariate and multivariate analyses of factors associated with survival were performed. Multivariate analysis showed that age at alloHSCT of ≤ 31 years, MRD, successful engraftment, absence of acute graft-versus-host disease (aGVHD), and platelet engraftment at ≤ 21 days, were independent predictors of longer survival. In addition, time to aGVHD and cumulative nonrelapse mortality (NRM) were better in MRD than in AD recipients. Using propensity score matching (PSM), we performed a case-control study comparing 25 patients in each group who underwent alloHSCT from MRDs and ADs. Pretransplantation clinical factors were well balanced in either group. Median survival time was similar, and no statistically significant difference in transplantation outcomes was apparent when MRD and AD recipients were compared. In conclusion, our results suggest that alloHSCT from an AD should be considered earlier in adult patients with AA who do not have an MRD.Biology of blood and marrow transplantation: journal of the American Society for Blood and Marrow Transplantation 01/2011; 17(9):1289-98. · 3.15 Impact Factor -
Article: Prognostic significance of serum vascular endothelial growth factor per platelet count in unresectable advanced gastric cancer patients.
[show abstract] [hide abstract]
ABSTRACT: Angiogenesis is one of the crucial steps in various solid tumor growth and metastasis. However, there are limited data regarding the clinical and prognostic significance of serum vascular endothelial growth factor levels per platelet count in unresectable advanced gastric cancer compared with early gastric cancer and healthy volunteers. A total of 181 gastric cancer patients were included and control serum samples were acquired from 113 healthy volunteers. The levels of serum vascular endothelial growth factor were measured using human vascular endothelial growth factor quantitative enzyme-linked immunosorbent assay. Survival curves were calculated using the Kaplan-Meier method and survival comparisons were made by the log-rank test in metastatic gastric cancer. There was a significant correlation between serum vascular endothelial growth factor levels and differentiation of tumor (P = 0.014), stage (P = 0.036). The overall survival (P = 0.0432) and the progression-free survival (P = 0.0116) were significantly shorter in patients with high serum vascular endothelial growth factor per platelet count (≥1.626 pg/10(6)). In the multivariate analysis, the presence of peritoneal carcinomatosis (P = 0.039), serum vascular endothelial growth factor per platelet (P = 0.005) were found to be significantly associated with poor progression-free survival. This study demonstrates that serum vascular endothelial growth factor per platelet count is correlated with poor overall survival and progression-free survival in patients with advanced gastric cancer.Japanese Journal of Clinical Oncology 12/2010; 40(12):1147-53. · 1.78 Impact Factor -
Article: Wernicke's encephalopathy following allogeneic hematopoietic stem cell transplantation.
[show abstract] [hide abstract]
ABSTRACT: Wernicke's encephalopathy is caused by thiamine deficiency, and is characterized by acute mental confusion, ataxia, and ophthalmoplegia. It is also a rare neurologic complication of hematopoietic stem cell transplantation (HSCT). However, because of its rare incidence, Wernicke's encephalopathy can easily be overlooked in HSCT patients, and a few misleading steps in the early stage of the disease may result in permanent neurologic disability or even mortality. We recently encountered a case of Wernicke's encephalopathy in a patient who underwent allogeneic HSCT. Based on our own experience and previously published documents, we suggest early radiologic surveillance and treatment for patients with findings compatible with Wernicke's encephalopathy following HSCT.The Korean journal of hematology 12/2010; 45(4):279-81.
