Abstract
BACKGROUND Assessment of bone marrow involvement (BMI) in non-Hodgkin lymphoma (NHL) is crucial for determining patient prognosis and treatment strategy. We assessed the prognostic value of next-generation sequencing (NGS)-based immunoglobulin (Ig) gene clonality analysis as an ancillary test for BMI evaluation in NHL. METHODS A retrospective cohort of 124 patients newly diagnosed with B-cell NHL between 2019 and 2022 was included. NGS-based Ig clonality analysis was conducted using LymphoTrak IGH FR1 Assay and IGK Assay (Invivoscribe Technologies, San Diego, CA, USA) on BM aspirate samples, and the results were compared with those of histopathological BMI (hBMI). RESULTS Among the 124 patients, hBMI was detected in 16.9% (n = 21). The overall agreement of BMI between Ig clonality analyses and histopathological analysis for IGH, IGK, and either IGH or IGK was 86.3%, 92.7%, and 90.3%. The highest positive percent agreement was observed with clonal rearrangements of either IGH or IGK gene (90.5%), while the highest negative percent agreement was observed with clonal rearrangement of IGK gene (96.1%). For the prediction of hBMI, positive prediction value ranged between 59.1% and 80.0% and the negative prediction value ranged between 91.3% and 97.9%. CONCLUSION NGS-based clonality analysis is an analytic platform with a substantial overall agreement with histopathological analysis. Assessment of both IGH and IGK genes for the clonal rearrangement analysis could be considered for the optimal diagnostic performance of BMI detection in B-cell NHL.

Abstract
BACKGROUND/AIMS Although rituximab, an antiCD20 monoclonal antibody, has dramatically improved the clinical outcomes of diffuse large B-cell lymphoma, rituximab resistance remains a challenge. METHODS We developed a rituximab-resistant cell line (RRCL) by sequential exposure to gradually increasing concentrations of rituximab in a rituximab-sensitive cell line (RSCL). When the same dose of rituximab was administered, RRCL showed a smaller decrease in cell viability and apoptosis than RSCL. To determine the differences in gene expression between RSCL and RRCL, we performed next-generation sequencing. RESULTS In total, 1,879 differentially expressed genes were identified, and in the over-representation analysis of Consensus-PathDB, mitogen-activated protein kinase (MAPK) signaling pathway showed statistical significance. MAPK13, which encodes the p38δ protein, was expressed more than four-fold in RRCL. Western blot analysis revealed that phosphop38 expression mainwas increased in RRCL, and when p38 inhibitor was administered, phosphop38 expression was significantly decreased. Therefore, we hypothesized that p38 MAPK activation was associated with rituximab resistance. Previous studies have suggested that p38 is associated with NF-κB activation. Deferasirox has been reported to inhibit NF-κB activity and suppress phosphorylation of the MAPK pathway. Furthermore, it also has cytotoxic effects on various cancers and synergistic effects in overcoming drug resistance. In this study, we confirmed that deferasirox induced dose-dependent cytotoxicity in both RSCL and RRCL, and the combination of deferasirox and rituximab showed a synergistic effect in RRCL at all combination concentrations. CONCLUSION We suggest that p38 MAPK, especially p38δ, activation is associated with rituximab resistance, and deferasirox may be a candidate to overcome rituximab resistance.

Abstract
AIM Gene expression analysis facilitates the detection of diagnostic and prognostic biomarkers for myeloid haematological malignancies. The Oncomine Myeloid Research Assay (OMA; Thermo Fisher Scientific, Massachusetts, USA) provides a comprehensive analysis of gene expression of five target genes, along with gene alteration and fusion. Here, we present the performance of the OMA for gene expression analysis. METHODS In total, 53 RNA samples from patients diagnosed with acute myeloid leukaemia (AML) or myelodysplastic syndrome were included. Of these 53 samples, 3 were evaluated for reproducibility and 50 were evaluated for comparison with RNA-sequencing (RNA-seq). The prognostic impact of the gene expression profile produced by both OMA and RNA-seq in AML was investigated using follow-up data from 33 patients with AML. RESULTS The OMA showed good intrarun and interrun reproducibility. Compared with the RNA-seq results, high correlations were found in BAALC, MECOM and WT1 (all r>0.9), with moderate correlations in MYC (r=0.75, p<0.001) and SMC1A (r=0.42, p=0.002). The agreement between OMA and RNA-seq in classifying the dysregulated expression group was almost perfect, except for SMC1A (κ=0.175). Among these five genes, only BAALC showed a significant clinical impact in patients with AML. Patients with high BAALC expression showed significantly shorter overall survival based on both OMA (p=0.037) and RNA-seq (p=0.003). CONCLUSIONS OMA gene expression analysis offers reproducible and accurate gene expression data for most targeted genes and demonstrates the utility of BAALC expression as a prognostic marker in AML.

Abstract
INTRODUCTION Pre-emptive therapy for cytomegalovirus (CMV) reactivation has been used in allogeneic hematopoietic stem cell transplantation (allo-HSCT). It is unclear if this strategy has poorer clinical outcomes in CMV-endemic areas and if more aggressive prophylaxis is required. METHODS We retrospectively analyzed the patterns and survival after CMV reactivation in patients undergoing pre-emptive therapy following allo-HSCT and assessed high-risk patients who could benefit from aggressive CMV prophylaxis in endemic areas. RESULTS Of the 292 patients who underwent allo-HSCT, 70.5% (donor+ or recipient+) were CMV seropositive. CMV reactivation occurred in 139 patients (47.6%), with a median of 31.5 days from day 0 of allo-HSCT. The overall survival of patients with CMV reactivation who received pre-emptive therapy did not differ from those without reactivation. Of the 139 patients with CMV reactivation, 78 (56.1%) underwent ≥2 rounds of pre-emptive therapy. In multivariate analysis, the risk of CMV reactivation was higher in patients with multiple myeloma, with CMV seropositivity of the recipient and donor, administered with a higher dose of anti-thymocyte globulin (ATG), and with acute graft-versus-host disease (aGVHD) ≥ grade 2. CONCLUSION Although half of the patients with allo-HSCT were administered with pre-emptive therapy for CMV, CMV reactivation did not affect their survival, indicating the advantages of pre-emptive therapy, even in CMV-endemic areas. The cost-effectiveness of more aggressive CMV prophylaxis should be re-evaluated in patients at a high risk for CMV reactivation.

Abstract
The fifth edition of the WHO classification (2022 WHO) and the International Consensus Classification (2022 ICC) of myeloid neoplasms have been recently published. We reviewed the changes in the diagnosis distribution in patients with MDS with excess blasts (MDS-EB) or AML using both classifications. Forty-seven patients previously diagnosed as having AML or MDS-EB with available mutation analysis data, including targeted next-generation and RNA-sequencing data, were included. We reclassified 15 (31.9%) and 27 (57.4%) patients based on the 2022 WHO and 2022 ICC, respectively. One patient was reclassified as having a translocation categorized as a rare recurring translocation in both classifications. Reclassification was mostly due to the addition of mutation-based diagnostic criteria (i.e., AML, myelodysplasia-related) or a new entity associated with TP53 mutation. In both classifications, MDS diagnosis required the confirmation of multi-hit TP53 alterations. Among 14 patients with TP53 mutations, 11 harbored multi-hit TP53 alterations, including four with TP53 mutations and loss of heterozygosity. Adverse prognosis was associated with multi-hit TP53 alterations (P=0.009) in patients with MDS-EB, emphasizing the importance of detecting the mutations at diagnosis. The implementation of these classifications may lead to the identification of different subtypes from previously heterogeneous diagnostic categories based on genetic characteristics.

Abstract
BACKGROUND Although various coronavirus disease 2019 (COVID-19) vaccines have been delivered to the public worldwide, data on cancer populations are limited. Vaccine hesitancy related to safety concerns is observed among cancer patients. We report the perception of COVID-19 vaccines and their safety profile after vaccination among cancer patients. MATERIALS AND METHODS Between April and November 2021, a multicenter survey was conducted on 318 patients treated in any hemato-oncology outpatient clinic among three hospitals under the Korea University Medical Center. The medical records of the patients were reviewed to obtain detailed clinical and hematological toxicity data. RESULTS A perception survey was conducted among 293 patients. Among them, 53.9% were concerned about developing vaccine-related adverse events (VRAEs) and 23.5%, about negative effects on cancer treatment. During the study period, 255 and 186 patients participated in a safety survey after the first and second doses, respectively. After the first dose, 62% of patients reported VRAEs (2.4%, grade 3), whereas 48.9% reported VRAEs (2.7%, grade 3) after the second dose. For both doses, injection-site pain and sore arm pain were the most common VRAEs, followed by myalgia, fatigue, and headache. No grade 4/5 VRAEs were observed, and there were no differences in complete blood count after vaccination. Multivariate analysis revealed female sex, active cancer treatment, and mRNA vaccines as independent risk factors for VRAE development in cancer patients. CONCLUSION Despite high levels of concern, COVID-19 vaccines were well tolerated by cancer patients, with a safety profile consistent with that of the general population.

Abstract
Background: Cytomegalovirus (CMV) reactivation is a common complication in patients undergoing allogeneic stem cell transplantation. However, the incidence of CMV reactivation is low after autologous stem cell transplantation (auto-SCT), and the prognostic value of CMV reactivation remains controversial. Moreover, reports on late CMV reactivation after auto-SCT are limited. We aimed to analyze the association between CMV reactivation and survival outcomes and develop a predictive model for late CMV reactivation in patients undergoing auto-SCT. Methods: Data of 201 patients who underwent SCT at the Korea University Medical Center from 2007 to 2018 were collected. We analyzed prognostic factors for survival outcomes after auto-SCT and risk factors for late CMV reactivation using a receiver operating characteristic curve. Then, we developed a predictive risk model for late CMV reactivation based on results of the risk factor analysis. Results: Early CMV reactivation was significantly associated with better overall survival (OS) (hazard ratio [HR], 0.329; P = 0.045) in patients with multiple myeloma; however, no significant differences were observed in patients with lymphoma. For late CMV reactivation, a serum lactate dehydrogenase level greater than the upper limit of normal (HR, 2.251; P = 0.027) and late CMV reactivation (HR, 2.964; P = 0.047) were independent risk factors for poor OS, while lymphoma diagnosis (vs. multiple myeloma; HR, 0.389; P = 0.016) was an independent risk factor for good OS. In risk factor analysis for late CMV reactivation, T-cell lymphoma diagnosis (odds ratio [OR], 8.499; P = 0.029), ≥ two prior chemotherapies (OR, 8.995; P = 0.027), failure to achieve complete response (CR) after transplantation (OR, 7.124; P = 0.031), and early CMV reactivation (OR, 12.853; P = 0.007) were significantly associated with late CMV reactivation. To develop the predictive risk model for late CMV reactivation, a score (1 to 1.5) was assigned for each of the above-mentioned variables. The optimal cutoff value (1.75 points) was calculated using the receiver operating characteristic curve. The predictive risk model showed good discrimination, with an area under the curve of 0.872 (standard error, 0.062; P < 0.001). Conclusions: Late CMV reactivation was an independent risk factor for inferior OS, whereas early CMV reactivation was associated with better survival in patients with multiple myeloma. This risk prediction model could be helpful in identifying high-risk patients who require monitoring for late CMV reactivation and potentially benefit from prophylactic or preemptive therapy.

Abstract
Epstein-Barr virus-infected B cells are found at high frequency in peripheral T cell lymphoma. Herein, we report a case involving excessive EBV-positive B cells accompanying peripheral T cell lymphoma, not otherwise specified in the nasopharynx masquerading as nasopharyngeal extranodal NK/T cell lymphoma. A large number of Epstein-Barr virus-infected B cells infiltrate in between CD3-positive cytotoxic tumor T cells, as if EBV was infecting tumor T cells. After chemotherapy, the T cell lymphoma population decreased, but the B cell population expanded to form EBV-positive diffuse large B cell lymphoma in the tonsils and nasopharynx. At the follow-up, bone marrow biopsy exhibited infiltration of composite peripheral T cell lymphoma, not otherwise specified, and EBV-positive diffuse large B cell lymphoma. Although this condition is rare, the cell lineage of EBV-infected cells must be confirmed when diagnosing extranodal NK/T cell lymphoma to exclude the possibility of misdiagnosis by Epstein-Barr virus-infected B cells.

Abstract
Composite lymphoma is very rare and a combination of Hodgkin lymphoma and non-Hodgkin lymphoma and even histiocytic tumors can occur. Because of the unfamiliarity, not only can this cause diagnostic problems, but can also affect treatment plan. We report a case of composite lymphoma in a 40-year-old male. Initial biopsy showed a composite lymphoma of follicular lymphoma grade 1 and classic Hodgkin lymphoma. After chemotherapy, another lymph node was taken because of disease progression, which revealed follicular lymphoma, grade 3a without Hodgkin lymphoma component.

Abstract
BACKGROUND/AIMS Relatively little data are available on how the response to the coronavirus disease 2019 (COVID-19) pandemic has affected treatment outcomes in patients receiving chemotherapy for lymphoma or multiple myeloma. We aimed to determine the effect of COVID-19 countermeasures on treatment outcomes in this patient population. METHODS We retrospectively analyzed data on patients treated for lymphoma or multiple myeloma in two tertiary hospitals in Seoul. Patients were divided into two groups: group 1 included patients who received chemotherapy between September and December 2019 (the control period), and group 2 included patients who received chemotherapy between September and December 2020 (the study period). Countermeasures to COVID-19 were applied to the patients in group 2. The countermeasures implemented included mask wearing and regular handwashing at home and in hospital; COVID-19 risk assessments on all hospital visitors; and pre-emptive COVID-19 screening for all newly hospitalized patients and their resident guardians. RESULTS No differences in treatment outcomes, including treatment response, incidence and duration of neutropenia or neutropenic fever, delays in chemotherapy, or number of deaths during chemotherapy, were observed between the g roups. None of the patients in group 2 tested positive for COVID-19, and there were no COVID-19-related deaths during the study period. CONCLUSION Countermeasures to COVID-19 did not affect treatment outcomes in patients receiving chemotherapy for lymphoma or multiple myeloma. Data on the effect of countermeasures to COVID-19 on treatment outcomes should continue to be analyzed to ensure that treatment outcomes are not adversely affected.

Abstract
In clinical practice, most patients with monoclonal gammopathy of undetermined significance (MGUS) undergo long-term follow-up without disease progression. There is insufficient real-world data about how closely and whether anything other than disease progression should be monitored. Herein, we performed a nationwide study of 470 patients with MGUS with a 10-year follow-up to determine the patterns of disease progression and other comorbidities. During the follow-up period, 158 of 470 patients with MGUS (33.62%) progressed to symptomatic monoclonal gammopathies. Most of these were multiple myeloma (134/470 patients, 28.51%), and those diagnosed within 2 years after diagnosis of MGUS was high. Approximately 30-50% of patients with MGUS had hypertension, diabetes, hyperlipidemia, and osteoarthritis at the time of diagnosis, and these comorbidities were newly developed during the follow-up period in approximately 50% of the remaining patients with MGUS. Approximately 20-40% of patients with MGUS have acute or chronic kidney failure, thyroid disorders, disc disorders, peripheral neuropathy, myocardial infarction, stroke, and heart failure during the follow-up period. Altogether, when MGUS is diagnosed, close follow-up of the possibility of progression to multiple myeloma is required, especially within 2 years after diagnosis; simultaneously, various comorbidities should be considered and monitored during the follow-up of patients with MGUS. Continuous research is needed to establish appropriate follow-up guidelines.

Abstract
Background Cereblon (CRBN) is a direct target of immunomodulatory drugs (IMiDs) and is known to be sensitive and responsive to IMiD therapy. We evaluated CRBN expression in bone marrow plasma cells and analyzed whether CRBN expression was associated with multiple myeloma prognosis. Lastly, we developed a nomogram model for predicting high CRBN expression based on clinically significant blood markers. Methods We evaluated 143 multiple myeloma patients (internal dataset) who underwent bone marrow examinations. For evaluating the prognostic ability of the nomogram model, two external cohorts (235 patients in external dataset 1 and 156 patients in external dataset 2) were analyzed. The expression of CRBN in bone marrow aspirate samples was evaluated using immunohistochemistry. High CRBN expression was defined as the study-defined H-score ≥6. Results In the high CRBN group, the median progression-free survival (PFS) and overall survival (OS) of patients receiving the IMiD-based therapy and non-IMiD therapy were 29 and 10 months for PFS, and NR (not reached) and 54 months for OS, respectively. IMiD-based therapy was significantly associated with better PFS and OS outcomes. High CRBN expression was independently predicted by female sex, high serum free-light chain (FLC) ratio, higher serum M-protein level, and higher β2-microglobulin level. Based on these results, we constructed a new nomogram model to predict high CRBN expression and the effectiveness of IMiD therapy in multiple myeloma. Conclusion This nomogram could improve the prognostic evaluation of myeloma patients exhibiting high CRBN expression treated with IMiD therapy and might help provide personalized treatment strategies to clinicians.

Abstract
BACKGROUND/AIMS Nilotinib is used for treating patients with imatinib-sensitive or -resistant chronic myeloid leukemia (CML); however, nilotinib-resistant cases have been observed in recent years. In addition, a considerable number of patients receiving nilotinib developed diabetes. Metformin is a front-line drug for the treatment of type 2 diabetes, and several studies have shown that diabetes patients treated with metformin have reduced incidence of cancer. This study aimed to define the effect of metformin on CML cells to determine whether metformin overcomes nilotinib resistance, and to identify novel targets for the treatment of nilotinib resistance. METHODS We observed the effects of metformin and nilotinib on K562 and KU812 human CML cell lines. Nilotinib-resistant CML cell lines were generated by exposing cells to gradually increasing doses of nilotinib. Then, we investigated the driving force that makes resistance to nilotinib and the effect of metformin on the driving force. RESULTS Sub-toxic doses of metformin enhanced nilotinib efficacy by reducing Bcl-xL expression, which induces apoptosis in CML cells. Next, we generated nilotinib-resistant K562 and KU812 cell lines that overexpressed the c-Jun N-terminal kinase (JNK) gene. JNK silencing by a JNK inhibitor restored sensitivity to nilotinib. Furthermore, metformin was effective in decreasing phosphorylated JNK levels, restoring nilotinib sensitivity. Combined treatment with nilotinib and metformin was more effective than combined treatment with nilotinib and a JNK inhibitor in terms of cell proliferation inhibition. CONCLUSION This study suggested that combination therapy with metformin and nilotinib may have clinical benefits of enhancing antileukemia efficacy and overcoming resistance to nilotinib.

Abstract
Background: Although many acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS)
patients have been treated with hypomethylating agents (HMAs) as a
substitute for intensive chemotherapy in recent years, the incidence of
invasive fungal infections (IFIs) and the efficacy of posaconazole as
antifungal prophylaxis in these patients are not well known to date. Methods: We retrospectively analyzed 280 AML and MDS patients treated with HMAs to
identify IFI incidence and posaconazole efficacy as antifungal prophylaxis
in these patients. Results: The overall incidence of probable or proven IFIs was 7.9% (22/280 patients):
11.5% in the no-use group (17/148 patients) and 3.8% in the posaconazole
group (5/132 patients). Most IFIs occurred during the early cycles of the
HMAs (median: 3 cycles; range: 1–8 cycles), especially in patients who had
neutropenia or did not respond to HMAs. Posaconazole significantly lowered
IFI incidence compared with that in the no-use group in univariate and
multivariate analyses. Moreover, patients who had reduced liver function at
HMA initiation, were treated with decitabine therapy, and did not respond to
HMA chemotherapy were independently associated with a higher IFI risk. In
subgroup analysis, posaconazole appeared to be more beneficial for patients
with good Eastern Cooperative Oncology Group performance score or liver
function at HMA initiation. Conclusion: Thus, in AML and MDS patients receiving HMAs, IFI risk may be high during the
early cycles, especially when the underlying disease is not controlled.
Posaconazole could represent antifungal prophylaxis in these patients;
further studies are needed for its appropriate indications.

Abstract
BACKGROUND/AIMS Various preoperative screening tests, such as platelet count, prothrombin time, activated partial thromboplastin time, and bleeding time, have been widely used to evaluate the risk of bleeding during surgery. Use of platelet function analyzer (PFA)-100/200 for assessing platelet function instead of bleeding time is increasing. However, its role in predicting the perioperative risk of bleeding remains controversial. METHODS Data of 703 patients who underwent surgery under general anesthesia were retrospectively analyzed. Preoperative platelet function was measured using PFA-200 system and the association with intraoperative bleeding was assessed. Additionally, other variables that could affect PFA-200 results were assessed by logistic regression analysis. RESULTS Collagen/epinephrine (COL/EPI) test was prolonged in 199/703 (28.3%) patients (EPI group), while 99/212 (46.7%) patients showed COL/adenosine diphosphate test abnormalities. Bleeding over 300 mL during surgery occurred in 14.3% and 20.1% of patients in the normal and EPI groups, respectively (p = 0.058). In addition, red blood cell transfusion within 72 hours after surgery rate was significantly higher in the EPI group than in the normal group (31.7% vs. 23.4%, p = 0.024). In multivariate logistic analysis, prolongation closure time with COL/EPI (p = 0.068) was marginally associated with risk of bleeding during surgery. Furthermore, PFA-200 results were influenced by various factors, such as nonsteroidal anti-inflammatory drug use, blood group, hematocrit, and time of blood collection. CONCLUSION Preoperative PFA-200 test may be helpful in predicting the risk of perioperative bleeding. However, its results should be carefully interpreted because they are affected by several factors.

Abstract
Our aim was to compare the efficacy and safety of two recently developed biosimilars of pegfilgrastim, a pegylated form of the recombinant human granulocyte‐colony stimulating factor (G‐CSF) analog filgrastim with those of the reference pegfilgrastim. We retrospectively analyzed data from patients diagnosed with diffuse large B‐cell lymphoma (DLBCL) who were treated with first‐line R‐CHOP chemotherapy and received pegylated G‐CSF for primary prophylaxis. The following pegylated G‐CSFs were analyzed in this study: reference pegfilgrastim (Neulasta®) and two of its biosimilars (tripegfilgrastim; Dulastin® and pegteograstim; Neulapeg®). In total, 296 patients were enrolled. The number of patients with at least one episode of neutropenia during R‐CHOP chemotherapy was the lowest in the reference cohort (pegfilgrastim: 127 of 193 patients, 65.8%; tripegfilgrastim: 64 of 69 patients, 92.8%; pegteograstim: 28 of 34 patients, 82.4%, P < .001). The number of patients with at least one episode of febrile neutropenia was also lowest in the reference cohort (pegfilgrastim: 67 of 193 patients, 34.7%; tripegfilgrastim: 38 of 69 patients, 55.1%; pegteograstim: 16 of 34 patients, 47.1%, P = .009). There were no differences in the duration of neutropenia and febrile neutropenia or treatment outcomes (rate of complete response or relapse and survival). There were no reports of grade 3 or higher adverse events requiring discontinuation of prophylactic pegylated G‐CSF in any group. The safety of the pegfilgrastim biosimilars for prophylactic purposes was comparable to that of the reference pegfilgrastim; however, in terms of their efficacy, the incidence of neutropenia and febrile neutropenia tended to be higher than that when using pegfilgrastim. The clinical relevance of these results in the biosimilar cohorts should be explored.

Abstract
BACKGROUND/AIMS The diagnosis of immune thrombocytopenia (ITP) is based on clinical manifestations and there is no gold standard. Thus, even hematologic malignancy is sometimes misdiagnosed as ITP and adequate treatment is delayed. Therefore, novel diagnostic parameters are needed to distinguish ITP from other causes of thrombocytopenia. Immature platelet fraction (IPF) has been proposed as one of new parameters. In this study, we assessed the usefulness of IPF and developed a diagnostic predictive scoring model for ITP. METHODS We retrospectively studied 568 patients with thrombocytopenia. Blood samples were collected and IPF quantified using a fully-automated hematology analyzer. We also estimated other variables that could affect thrombocytopenia by logistic regression analysis. RESULTS The median IPF was significantly higher in the ITP group than in the non-ITP group (8.7% vs. 5.1%). The optimal cut-off value of IPF for differentiating ITP was 7.0%. We evaluated other laboratory variables via logistic regression analysis. IPF, hemoglobin, lactate dehydrogenase (LDH), and ferritin were statistically significant and comprised a diagnostic predictive scoring model. Our model gave points to each of variables: 1 to high hemoglobin (> 12 g/dL), low ferritin (≤ 177 ng/ mL), normal LDH (≤ upper limit of normal) and IPF ≥ 7 and < 10, 2 to IPF ≥ 10. The final score was obtained by summing the points. We defined that ITP could be predicted in patients with more than 3 points. CONCLUSION IPF could be a useful parameter to distinguish ITP from other causes of thrombocytopenia. We developed the predictive scoring model. This model could predict ITP with high probability.

Abstract
Eculizumab is effective in managing patients with paroxysmal nocturnal hemoglobinuria (PNH). In South Korea, the financial support for eculizumab therapy is extended by the National Health Insurance Services (NHIS) only to patients with high-risk PNH for approximately 10 years. In this study, we performed a nationwide analysis of the real-world efficacy of eculizumab therapy in patients diagnosed with PNH between January 1, 2002, and December 31, 2016, by using the NHIS database. Patients treated with eculizumab (the eculizumab-treated group) exhibited a significantly higher survival rate than patients not treated with eculizumab (the eculizumab-untreated group), with 4-year survival rates after propensity score matching of 98.31% and 79.67%, respectively (p = 0.0489). The mean red blood cell (RBC) transfusion units per 12 months after eculizumab therapy were significantly lower than that before eculizumab therapy (5.75 units vs. 12.28 units, p < 0.0001). The median time for the first transfusion in the eculizumab-treated group was significantly longer than that in the eculizumab-untreated group. The 4-year transfusion-independence rate for the eculizumab-treated group was significantly higher than that for the eculizumab-untreated group (20.81% vs. 10.24%, p = 0.078). There was no significant difference between the two groups in the incidence of new documented complications related to PNH. In conclusion, eculizumab therapy for patients with high-risk PNH may effectively improve the survival rate and reduce the transfusion requirement. Paradoxically, eculizumab-treated patients with severe PNH exhibit a higher survival rate than eculizumab-untreated patients with less severe PNH.

Abstract
Numerous studies have analysed the clinical efficacies of hypomethylating agents (HMAs) in patients with myelodysplastic syndromes (MDS). However, reports that compare the two HMAs, decitabine and azacitidine, in patients with lower-risk (low and intermediate-1) MDS are limited. We compared 5-day decitabine and 7-day azacitidine regimens in terms of treatment responses, survival outcomes, and adverse events in patients with lower-risk MDS with poor prognostic features. The overall response rates (ORRs) were 67.2% and 44.0% in the patients treated with decitabine and azacitidine, respectively (P = 0.014). While the median progression-free survival (PFS) was significantly better in the patients treated with decitabine than in those treated with azacitidine (P = 0.019), no significant differences in event-free and overall survival rates were observed between the two groups. Multivariate analysis revealed that compared with azacitidine treatment, decitabine treatment is significantly associated with a higher ORR (P = 0.026) and longer PFS (P = 0.037). No significant differences were observed in the incidence of grade 3 or higher haematologic adverse events in response to the two HMAs. In conclusion, in lower-risk MDS, especially with poor prognostic features, ORR and PFS were significantly better with 5-day decitabine treatment than with 7-day azacitidine treatment, with comparable safety.

Abstract
BACKGROUND/AIMS Bortezomib plus melphalan-prednisone (VMP) is a standard treatment for multiple myeloma, particularly for patients who are ineligible for high-dose therapy. However, early discontinuation or treatment modification is often needed owing to adverse events. The aim of this study was to investigate the clinical outcomes of modifying the dose of melphalan-prednisone (MP) in patients receiving VMP. METHODS We examined 67 patients who received a modified dose of MP, and 38 patients who received the regularly planned dose of MP. We then analyzed clinical differences between the groups. RESULTS Although there was no difference in the proportion of discontinuation due to adverse events between dose groups, more patients in the planned-dose group experienced earlier discontinuation in general. The overall response rate (ORR) was 81.0% and complete response (CR) rate was 30.5%. After a median 15.7 months of follow-up, the median progression-free survival (PFS) and overall survival (OS) were 25.0 and 47.8 months, respectively. There was no significant difference in the ORR, CR, PFS, and OS of the two dose groups. A median of four cycles were delivered, and the median cumulative bortezomib dose was 41.6 mg/m2 . The median PFS in patients with doses ≥ 41.6 mg/m2 was longer than that in patients with doses < 41.6 mg/m2 (35.1 months vs. 9.6 months). However, when MP was < 50% of the planned dose, PFS and OS were poor. CONCLUSION Modifying the dose of MP might be a feasible and effective therapeutic approach for multiple myeloma patients receiving VMP treatment.

Abstract
BACKGROUND/AIM Exosomes, derived from chronic myelogenous leukaemia (CML) cells, can be used as biomarkers and new targets for the detection of the BCR-ABL transcript. This study aimed to identify these possibilities. MATERIALS AND METHODS Human CML cell line-derived exosomes and CML-patients-derived exosomes were isolated with a size-exclusion chromatography column and ExoQuick™ exosome precipitation solution, respectively. Isolated exosomes were analysed by nested PCR to detect the BCR-ABL transcript. RESULTS Exosomes derived from the two human CML cell lines yielded a 250-bp band. RNA sequence analysis revealed 99% sequence homology with the partial mRNA for the human BCR-ABL chimeric protein. This ~250-bp band was also observed in the exosomes derived from patients with CML. However, only patients at the blast and accelerated phases showed the exosomal BCR-ABL transcript. CONCLUSION CML-derived exosomes could act as novel targets for the detection of the BCR-ABL transcript.

Abstract
BACKGROUND/AIMS The aims of this study were to identify the value of inflammatory markers as pretreatment prognostic factors for patients with multiple myeloma (MM) and to estimate the value of a prognostic index including these markers at diagnosis. METHODS A total of 273 newly diagnosed MM patients undergoing active treatment were analyzed in this study. The prognostic values for survival of the pretreatment inflammatory markers were investigated. A myeloma prognostic index (MPI) was derived using prognostic factors determined to be independently significant on multivariate analysis. RESULTS A high pretreatment neutrophil-lymphocyte ratio (NLR), low platelet count, and high C-reactive protein (CRP) level had independently unfavorable significance for overall survival (OS). The MPI was derived based on these factors. Per the MPI, 1 point each was assigned to high NLR, low platelet count, and high CRP. Risk categories were stratified into low- (score 0), intermediate- (score 1), and high-risk (score 2 or 3) groups. The MPI demonstrated independent statistical significance for OS on multivariate analysis ([intermediate: hazard ratio (HR), 1.91; 95% confidence interval (CI), 1.12 to 3.24] and [high: HR, 3.37; 95% CI, 2.00 to 5.69]; p < 0.001). Moreover, this significance could be observed regardless of age, renal function, and exposure to novel agents. In addition, the International Staging System risk group could be further significantly stratified using the MPI. CONCLUSIONS The MPI, consisting of pretreatment inflammatory markers, NLR, platelet count, and CRP, might be effective in predicting the survival of newly diagnosed MM patients undergoing active treatment.

Abstract
Small bowel tumors are very rare and generally malignant. As a result of the anatomical location and nonspecific manifestations of small bowel tumors, they are very difficult to diagnose. Balloon-assisted enteroscopy is a relatively noninvasive method compared to surgical resection, and allows for real-time observation, tissue confirmation with biopsy, and interventional procedures. Here, we report the case of a 69-year-old woman with a small bowel metastatic carcinoma observed with double balloon enteroscopy (DBE). She had a history of multiple cancers including ovarian cancer, bladder cancer, and breast cancer. The antegrade DBE procedure was performed before surgery for biopsy tissue confirmation. The patient underwent small bowel resection, and the final diagnosis was the same as that determined by preoperative biopsy. The final diagnosis was metastatic small bowel cancer originating from a cancer of the breast. This is the first detailed report of the preoperative diagnosis of small intestinal metastatic breast cancer by DBE.

Abstract
BACKGROUND The efficacy of second-line chemotherapy (CT2) after the failure of first-line chemotherapy (CT1) for advanced biliary tract cancer (BTC) has not been established. We investigated the favorable prognostic factors for CT2 to determine which patients could be expected to benefit from CT2. METHODS From a total of 168 patients who were treated with chemotherapy at our institution between January 2003 and December 2012, we retrospectively reviewed 50 patients who received CT2. Patients were treated with various chemotherapeutic combinations as CT1 and CT2. RESULts: The median overall survival (OS) of patients who received and CT2 was 10.2 and 5.5 months, respectively. Good performance status (PS), a serum albumin level >3.5 g/dl and metastasis to only 1 organ were independent prognostic factors that affected the OS of the patients who received CT2. Patients who had only 1 metastastic organ, a good PS and a serum albumin level >3.5 g/dl at the beginning of CT2 demonstrated prolonged survival compared to patients who did not exhibit these 3 factors (9.5 vs. 4.3 months, p < 0.005). CONCLUSIONS CT2 should be considered for patients with advanced BTC, especially for those who have only 1 metastatic organ and remain in generally good medical condition after the failure of CT1.

Abstract
BACKGROUND Despite the advances in acute myeloid leukemia (AML) treatment, the prognosis of elderly patients remains poor and no definitive treatment guideline has been established. In the present study, we aimed to evaluate the effectiveness of intensive chemotherapy in elderly AML patients and to determine which subgroup of patients would be most responsive to the therapy. METHODS We retrospectively analyzed 84 elderly patients: 35, 19, and 30 patients were administered intensive chemotherapy, low-dose chemotherapy, and supportive care, respectively. RESULTS Among those who received intensive chemotherapy, there were 17 cases of remission after induction chemotherapy; treatment-related mortality was 22.9%. The median overall survival was 7.9 months. Multivariate analysis indicated that the significant prognostic factors for overall survival were performance status, fever before treatment, platelet count, blast count, cytogenetic risk category, and intensive chemotherapy. Subgroup analysis showed that intensive chemotherapy was markedly effective in the relatively younger patients (65-70 years) and those with de novo AML, better-to-intermediate cytogenetic risk, no fever before treatment, high albumin levels, and high lactate dehydrogenase levels. CONCLUSIONS Elderly AML patients had better outcomes with intensive chemotherapy than with low-intensity chemotherapy. Thus, appropriate subgroup selection for intensive chemotherapy is likely to improve therapeutic outcome.

Abstract
Visceral larva migrans (VLM) syndrome is a clinical manifestation of systemic organ involvement by Toxocara species. VLM with involvement of the bladder and liver is a rare finding. A 62-year-old woman presented with diffuse bladder wall thickening and multiple liver masses with peripheral eosinophilia and urinary symptoms. We considered malignancy or eosinophilic cystitis through clinical manifestations and imaging findings. However, no suspicious malignant lesions were observed on cystoscopy and liver mass biopsy revealed the presence of eosinophilic necrotizing granuloma without malignant cells. Anti-Toxocara antibodies were detected by western blotting and the patient was diagnosed with VLM syndrome. After taking prednisolone, urinary symptoms disappeared. On abdominal CT scan taken after three months, the size of multiple liver masses and bladder wall thickening had decreased. VLM syndrome should be suspected in patients with an atypical imaging pattern and peripheral eosinophilia.

Abstract
PURPOSE This article provides a review of the literature on the decline of hepatitis B virus (HBV) infection in Asian and Pacific nations having universal hepatitis B immunization programs. METHODS Papers on the epidemiology of HBV infection and hepatitis B immunization programs in Asian and Pacific nations were located by searching MEDLINE and libraries for publications in English, and by contacting hepatitis B experts. PRINCIPAL FINDINGS High endemicity for HBV in Asian and Pacific nations was partly caused by a cycle of high infectiousness, perinatal transmission, and chronic infection from early ages. Higher prevalence of infection has been found in men, some families, communities, and ethnic groups, and in people with high risk behaviors and situations, such as attending day care, getting injections, or sharing personal items. Incidence of acquisition of infection is about 2%-5% per year. Prevalence of HBV infection was declining in some nations before commencing hepatitis B immunization programs, probably because of improvements in medical practices and living conditions. Twenty-seven of 34 Pacific and East and Southeast Asian nations have attained >70% hepatitis B vaccination coverage in infants, and twelve have documented reducing infection or liver cancer to fractions of their former rates. But the immunization programs may be causing natural selection of mutant hepatitis B viruses, necessitating study of the mutants, and modification of serological tests and vaccines. CONCLUSIONS Practical implications for U.S. health professionals are: increasing HBV screening and hepatitis B vaccination of adolescents and adults from Asian and Pacific nations can prevent many infections and disease cases; most children coming from high coverage Asian and Pacific nations will be immune and few infected; we can learn much from these successful programs; and we should still make efforts to immunize Asian and Pacific children in the United States, and help Asian and Pacific nations which do not yet have highly successful hepatitis B immunization programs.

Abstract
PURPOSE The purpose of this study was to describe breast and cervical cancer screening knowledge and practices of a representative sample of Chinese American women and to examine the factors associated with screening practices. DESCRIPTION OF STUDY A random sample of 332 Chinese American women, 40 to 69 years of age, from the Chinatown area of Chicago, Illinois, were interviewed face to face, using both Chinese Mandarin (or Putunghua) and Cantonese versions of the National Health Interview Survey (NHIS) Cancer Control Supplement Questionnaire. Knowledge and use of mammogram, clinical breast examination (CBE), breast self-examination (BSE), and Pap smear test were assessed. RESULTS The results showed a low level of knowledge of cancer screening tests and low use rates. Multiple logistics regression analysis showed that women with spoken English fluency were more likely to have knowledge and use of CBE, BSE, Pap test, and mammograms. Women with better than an elementary education were more likely to have knowledge and use of CBE, BSE, and Pap test. The source of medical care was statistically significant for having had a mammogram. Knowledge of cancer warning signs and symptoms was significant for knowledge of mammogram and BSE and for the use of BSE. CLINICAL IMPLICATIONS Multiple strategies are needed. These might include the following: 1) integration of research with population-based care by physicians and scientists; 2) coordinated public health education on cancer screening and postscreening support in Chinese languages; and 3) replication of the NHIS survey methodology and adaptive application of these instruments across several states and regions, combined with the assessment of screening performance in Chinese American populations.

Abstract
BACKGROUND Lamivudine has been reported to be able to stabilize liver enzyme and hepatitis B virus (HBV) replication with recurrent hepatitis that has been regarded as a frequent and major risk factor for hepatic dysfunction and chronic liver disease in renal transplant recipients. Because large number of hepatitis antigenemia patients among renal transplant patients experience recurrent hepatic dysfunction with HBV recurrence and permanent histological deterioration, preemptive or primary prophylactic use of lamivudine before transplantation may be more beneficial than a trial for the treatment of advanced hepatic dysfunction. METHODS We conducted a double arm study to compare the efficacy of lamivudine between the preemptive (HBV DNA positive) or prophylactic (HBV DNA negative) trial for the maintenance of stable liver function (n=10) and the trial for the salvage of advanced hepatic dysfunction developed after renal transplantation (n=6) in hepatitis B viremia carrier renal transplant recipients. RESULTS Hepatic dysfunction with recurrent HBV antigenemia developed in 11 of 36 (30.6%) hepatitis antigenemia patients with a mean duration of 8.4 months (range 5-19.4 months). In six patients treated with lamivudine after hepatic dysfunction from recurrent hepatitis B viremia, serum AST and ALT level normalized within 1 month and HBV-DNA disappeared in all cases. HBV-DNA, however, reappeared in three (50%) without any discontinuation of lamivudine. Liver biopsy revealed recurrent chronic active hepatitis with severe activity of fibrosis in four cases, cholestatic fibrosing hepatitis in one, and permanent cirrhotic change in one. In seven patients who had preemptive lamivudine treatment at 9, 6, 2, 2, 1, 0, 0 month before the transplantation, HBV-DNA had converted to negative with a mean follow up of 1.2 months (range 1-2 month) in all case. Three patients who had prophylactic trials with lamivudine have all remained HBV-DNA negative. The recurrence rate of HBV viremia in the preemptive or prophylactic lamivudine treated group is 10.0% (1/10), which is significantly lower than that (42.3%, 11/25) in the nonlamivudine-treated group. The re-recurrence rate of HBV viremia was significantly higher (3/6, 50.0%) in the reactive lamivudine treated group than in prophylactic or preemptive group (1/10, 10%). CONCLUSION Although lamivudine treatment after hepatic dysfunction can be a sound conventional treatment modality, this preliminary study may suggest that preemptive or prophylactic trial of lamivudine before hepatic dysfunction might be a more effective strategy for prevention of permanent histological deterioration and recurrence of hepatitis B viremia.

Abstract
PURPOSE/OBJECTIVES To examine nutrient intake of Korean Americans, especially those foods and supplements implicated in cancer. DESIGN Cross-sectional survey and descriptive analysis. SETTING Chicago, IL. SAMPLE 103 Korean Americans who were between 40 and 69 years of age. METHODS An Instrument, culturally and linguistically adapted from the Health Habits and History Questionnaire, was administered to assess nutrient intake from food and vitamin and mineral supplements. Bilingual interviewers collected data at respondents' homes. FINDINGS Relative to their diet in Korea, more than one-third of the respondents reported an increase in the consumption of beef, dairy products, coffee, soda, and bread, as well as a decrease in the intake of fish and rice and other grains. Compared to the general U.S. population included in the National Health Interview Survey (NHIS), Korean Americans had a greater intake of carbohydrates and vitamins A and C and lower intake of total fat, cholesterol, and saturated fat. Moreover, the percentages of calories were higher from carbohydrates and lower from fat, sweets, and alcohol for Korean Americans than those reported by NHIS respondents. Gender, education, and marital status were significantly associated with nutrient intake. The use of daily vitamin and calcium supplements was similar between respondents and those from NHIS. CONCLUSIONS At their stage of cultural adaptation, the incorporation of a larger quantity of Western food items did not make for a less healthy dietary pattern among respondents. Data showed that Korean Americans continued to consume diets more consistent with Korean than with American food patterns, in as much as greater than 60% of their calories came from carbohydrates and about 16% of calories from fat. As a group, respondents met the recommended dietary guidelines for most nutrients, except for dietary fiber and calcium. IMPLICATIONS FOR NURSING PRACTICE Variation in dietary intake by age, culture, gender, and years in the United States is well accepted. Effective cancer prevention and initiatives for dietary reform call for the incorporation of available research findings and considerable attention to data gaps regarding Korean Americans and other Asian Americans and Pacific Islander populations. Culturally competent, community-based programs should include the reinforcement of positive traditional dietary habits, encourage the adaptation of healthy Western food items, as well as assist minority populations in developing strategies that will effectively correct likely deficiencies in diet.

Abstract
PURPOSE The purpose of the study was to examine smoking behavior, knowledge, and beliefs among Korean Americans. DESCRIPTION OF STUDY One hundred four Korean American men and 159 women, 40 to 69 years old, living in Chicago, Illinois, served as study respondents. The National Health Interview Survey (NHIS) Cancer Control Supplement Questionnaire was used to collect data. The NHIS was translated into Korean with minor modifications to develop a culturally appropriate instrument. RESULTS This study suggests that smoking is almost exclusively a male behavior (38.5%) and that Korean American men smoke mostly cigarettes. Almost 90% of women have never smoked, whereas 23% of men reported never smoking. Respondents with a non-Christian background or no religious affiliation were 16.5 times more likely to be current smokers. Respondents who had lived in the United States less than 10 years were 12.5 times more likely to be current smokers. More than 90% of men, regardless of smoking status, were able to identify an association between smoking and major chronic diseases. CLINICAL IMPLICATIONS The prevalence of smoking among these Korean American men places them at considerable risk for smoking-related disease. Healthcare providers must be better informed about smoking behavior in this group, and specific attention to recently migrated men and those reporting religions other than Christianity is recommended. Health-protecting strategies for women and children who fall victim to secondhand smoke, or who may be targeted by tobacco advertising, are also an important step in disease prevention for this population.

Abstract
Previous studies have demonstrated that enalapril and verapamil seem to attenuate the cyclosporine nephrotoxicity. However, the mechanisms have not been completely understood, especially on molecular events. The aim of this study was to examine the effect of individual or combined treatment on osteopontin, TGF-beta, endothelin-1 and procollagen alpha 1(I) mRNA expressions. Enalapril (50 mg/L in drinking water) and verapamil (0.5 mg/kg/day, subcutaneously), alone or in combination, were administered to rats with chronic cyclosporine nephrotoxicity (cyclosporine, 25 mg/kg/day, subcutaneously) (n = 5 each). Five rats treated with olive oil vehicle were used as control. After 4 weeks, biochemical parameters were measured, and renal cortical mRNA levels were evaluated by Northern blot analysis. Cyclosporine reduced renal creatinine clearance significantly and induced renal cortical osteopontin, TGF-beta, endothelin-1 and procollagen alpha 1(I) gene expressions around 13.5 +/- 1.3, 2.4 +/- 0.2, 1.5 +/- 0.1, 1.9 +/- 0.1 folds, respectively. Individual treatment with enalapril or verapamil significantly suppressed the osteopontin and TGF-beta mRNA expression, but not endothelin-1 and procollagen alpha 1(I). Combined treatment also inhibited the osteopontin and TGF-beta mRNA expression but there was no difference between combined and individual treatment. In conclusion, enalapril or verapamil significantly blunted the cyclosporine-induced osteopontin and TGF-beta gene expressions. However, combined treatment did not show any additive effect.

Abstract
Cervical cancer is one of the most common cancers of American women. The Papanicolaou (Pap) smear test for cervical screening is a widely used and effective means to reduce the morbidity and mortality rate from cervical cancer through early detection. Despite these benefits, many women have never been screened or are not screened at regular intervals. The purpose of this study was to examine cervical cancer screening knowledge and practices of Korean-American women. The sample consisted of 159 Korean-American women, 40 to 69 years of age. The 1987 Cancer Control Supplement questionnaire was translated into Korean and used to collect data. Twenty-six percent of the respondents never heard of the Pap smear test. Only 34% of respondents reported having had a Pap smear test for screening. The most frequently cited reason for not having had a Pap smear test was absence of disease symptoms. Results indicate that education and usual sources of health care were significant factors related to having heard of or having had a Pap smear test. The findings from this study have important implications for health practitioners and policy makers who serve this ethnic population.

Abstract
BACKGROUND To investigate radiologic and pathological features of intestinal tuberculosis with abdominal complications. METHODS Twenty-two patients with 23 surgically proven complications (nine intestinal obstructions, eight perforations, three fistulae, and three intestinal bleeds) were analyzed. Medical records, radiologic studies, and pathologic examinations were reviewed with special emphasis on searching for the common features in each group of complication. RESULTS The most important single feature in seven of the nine patients with intestinal obstruction was the presence of stricture. In the remaining two patients, bowel adhesion was a primary cause of obstruction. In eight patients with intestinal perforation, both obstruction and ulcerations in the dilated proximal loop were the important features in six, and multiple deep ulcerations without obstruction was a primary cause in the remaining two. The common features in three patients with fistulae were focal or multiple strictures, severe adhesions, and fibrotic bowel wall. Intestinal bleeding originated from diffuse mucosal ulcerations. The abdominal complications occurred during antituberculous therapy in 10 of the 22 patients. CONCLUSION Understanding the radiologic and pathologic features of intestinal tuberculosis with complications help in making an appropriate clinical decision for the treatment strategy. Close observation is necessary, especially in those patients who are acutely ill during antituberculous medical therapy.

Abstract
BACKGROUND/AIMS Cell cycle control and the relationship that exists between cellular proliferation, the expression of cell cycle control proteins and cancer have been reported. This study was designed to decipher the timing of cell cycle control protein expression during the initiation of diethylnitrosamine-induced rat hepatocarcinogenesis. METHODS Three-week-old female Sprague-Dawley rats were intraperitoneally injected twice in 1 week with diethylnitrosamine; after the second injection, all animals were sacrificed at 1, 2 and 24 h, and 3 and 7 days. The expression of cell cycle-related proteins such as CDK2 and 4, cyclin proteins (D1, E and cdc2), proliferating cell nuclear antigen, tumor suppressor proteins (p53 and Rb), CDK inhibitory proteins (p21waf1 and p27Kip1), and apoptosis-inhibiting protein (bcl-2) following diethylnitrosamine treatment was examined. RESULTS The peak induction time of each cell cycle-related protein during DEN-induced cellular proliferation was diverse, and expressions of CDK2, CDK4, cdc2, p53, bcl-2, p21Waf1 and p27Kip1 appear to be of the greatest interest. CONCLUSIONS Data generated from this study may provide information about cell cycle-related protein expression in the initiation stage of hepatocarcinogenic signaling pathways stimulated by a genotoxic agent such as diethylnitrosamine.

Abstract
PURPOSE The purpose of this study was to examine knowledge and practices of colorectal cancer screening among Korean Americans. DESCRIPTION OF STUDY The sample consisted of 104 Korean American men and 159 women, 40 to 69 years of age, living in the Chicago area. The National Health Interview Survey (NHIS) Cancer Control Supplement Questionnaire, prepared by the National Center for Health Statistics, was used to collect data regarding colorectal cancer screening knowledge and practices. The NHIS questionnaire was translated into Korean with minor modification. RESULTS The percentage of male respondents ever having had a digital rectal exam (DRE) and fecal occult blood test (FOBT) were 13.5% and 10.6%, respectively. Only 11.3% of women reported DRE and 8.8% FOBT. Multiple logistic regression analysis results indicate that gender, education, knowledge of the seven cancer warning signals, and length of residence in the United States were significantly related to having heard of DRE. For those having had DRE, knowledge of the seven cancer warning signals, and length of residence in the United States were the only significant variables. Gender and education were significantly related to having heard of FOBT. None of the variables were found to be significantly related to having had FOBT. The findings indicate that a majority of respondents were unaware of these cancer screening examinations and forego these tests due to an underestimation of their importance. CLINICAL IMPLICATIONS The findings of this study underscore the importance of cancer education and further research addressing the cancer screening needs of Korean Americans. Currently, Korean Americans do not see healthcare providers or health brochures as valuable sources of health information. Therefore, healthcare professionals need to target this population by 1) coordinating their efforts with church and other community leaders and 2) developing health brochures that are in the Korean language and sensitive to the Korean culture.

Abstract
Studies of the elderly worldwide over the last 3 decades have reported that a self-rating of "poor" compared with "excellent/good" health increases the relative risk of dying. The authors tested the strength of this association by performing age-stratified Cox regression analyses on a 5-year longitudinal study of a representative sample of noninstitutionalized elderly aged 65 years and older (n=3,094) in a district of Shanghai, China. More than 20 potential confounders that were only partially controlled in other studies and threats to response validity due to cognitive impairment or diagnosed dementia that were not considered in previous studies were taken into account in this analysis. The results showed that among those aged 65-74 years, "poor" perceived health increases the adjusted relative risk of death by 1.93 (95% confidence interval 1.20-3.11) compared with "excellent/good" health. The adjusted relative risk of a "fair" rating of health is 2.16 (95% confidence interval 1.44-3.25). In the older age group, mortality risks for the ratings of fair as well as poor compared with excellent/good health were not statistically significant. The authors posit that several mechanisms related to host vulnerability markers and greater-than-expected utilization of health services may explain the association between self-assessed health and mortality risks. Future research should strive to develop more precise measures of these and related variables.

Abstract
Studies of migrants can generate hypotheses on the aetiology of cancer. Such studies are most informative when cancer incidence data are available both in the source and host country. We compared the incidence rate ratio of cancers (stomach, lung, female breast, colorectal and prostate) in Scandinavian immigrants to the US to US-born whites, using data from the SEER registry, 1973-89. Odds ratios (OR) for cancer sites in relation to birthplace were estimated using logistic regression. We also compared rate ratios (RR) for Scandinavian and US residents, using Poisson regression. Compared with US whites, most Scandinavian migrant groups had elevated OR for stomach cancer (1.58 to 3.92), and lower OR for lung cancer (0.38 to 0.88). Similarly, compared with US whites, residents of most Scandinavian countries had elevated RR for stomach cancer (1.47 to 3.33) and lower RR for lung cancer (0.27 to 0.97). Therefore, risk factors for lung and stomach cancers, such as smoking habits and Helicobacter pylori infection, respectively, may have been retained upon migration. Risks for breast, colorectal and prostate cancer among immigrants approached risks in the US (contrasting Scandinavian risks) suggesting assimilation of environmental and/or lifestyle factors.

Abstract
We investigated the status of the apolipoprotein E allele in 538 participants in the incidence phase of the ongoing Shanghai Survey of Dementia, including 103 demented subjects, 72 with mild cognitive impairment and 363 cognitively normal. The apo E epsilon 4 allele was present in 10.2% of control subjects and the allelic frequency did not change between ages 60 to 96 years. The apo E epsilon 4 allelic frequency was increased both in those wiht Alzheimer's disease (AD) (25.4%) and those with vascular dementia (VaD) (22.2%), but not in those with other dementing illnesses or the cognitively impaired. All of the subjects homozygous for apo E epsilon 4 were demented, three were diagnosed as having AD, and three met NINDS/AIREN criteria for VaD. The increased apo E epsilon 4 allelic frequency in clinically diagnosed VaD patients suggests that some of the infarcts are secondary to congophilic angiopathy. The adjusted odds ratio of developing AD in this community-derived study for persons with at least one apo E epsilon 4 allele was 4.1 (95% CI: 2.2, 7.7). Thus, the apo E epsilon 4 risk of developing AD in this Chinese cohort is similar to that in western community studies.

Abstract
Coping strategies were compared among family caregivers of Alzheimer's disease patients in Shanghai, China (n = 110) and San Diego, California (n = 139). Four coping factors were reliably consistent in both samples, supporting their widespread relevance to life adversity; behavioral confronting, behavioral distancing/social support, cognitive confronting, and cognitive distancing. Shanghai and San Diego caregivers endorsed similar rates of coping, but Shanghai caregivers reported fewer symptoms of depression and anxiety. Although coping strategies were similar, cultural ideals promoting family interdependence, veneration of elderly family members, and acceptance of traditional family roles may have reduced the psychological impacts of caregiving in the Shanghai sample.

Abstract
PURPOSE To evaluate the computed tomographic (CT) features of xanthogranulomatous cholecystitis (XGC) and to distinguish it from gallbladder carcinoma. MATERIALS AND METHODS Retrospective analysis was performed in 11 patients with XGC and 17 patients with gallbladder carcinoma in which the wall was thickened. The following CT features were analyzed: maximum wall thickness, intramural hypoattenuated nodules, mucosal line, patterns of wall thickening and enhancement, and the presence of stones. The changes outside the gallbladder were also compared. RESULTS The mean thickness of the gallbladder wall was 1.8 cm in patients with XGC and 2.1 cm in patients with gallbladder carcinoma. Intramural hypoattenuated nodules were seen in all patients with XGC but in only seven patients with gallbladder carcinoma (P = .008). The mucosal line was observed in nine patients with XGC and in six with gallbladder carcinoma (P = .02). The gallbladder wall was more diffusely thickened in patients with XGC (10 of 11 patients) than in patients with gallbladder carcinoma (seven of 17 patients) (P = .01). The occurrence of changes outside the gallbladder did not differ statistically significantly. CONCLUSION Because of a statistically significant overlap of CT features, only when intramural hypoattenuated nodules occupy a large area of the thickened gallbladder wall can the diagnosis of XGC be highly suggestive. The diagnosis of XGC at CT may indicate a less aggressive surgical approach.

Abstract
OBJECTIVES This paper analyzes data on the distribution of and risk factors for the acquired immunodeficiency syndrome (AIDS) and human immunodeficiency virus (HIV) infection in China. METHODS Ten years of data on persons tested for HIV infection and AIDS and the proportion who tested positive were analyzed against the background of China's population count. The Chinese- and English-language literature on HIV and AIDS from 1985 through 1995 was also reviewed. RESULTS Overall, more males than females had HIV infection. Intravenous drug use was the primary source of transmission, followed by heterosexual contacts. Only a small number of the persons tested were homosexual, but their proportion of HIV seropositivity ranked third to that of drug users; that of general hospital patients ranked fourth. CONCLUSIONS HIV infection and AIDS in China began as a highly regionalized and largely rural problem in Yunnan Province. However, HIV infection and AIDS have become an emerging urban problem. HIV seropositivity is low among several groups thought to have an elevated risk.
