ABSTRACT

INTRODUCTION: Reports on patients' satisfaction and preferred characteristics for treatments would be worthwhile when choosing an optimal treatment reflecting patients' perspectives. AIM: To identify the characteristics and treatment patterns of patients with haemophilia A, or their caregivers, in Korea and explore patient preferences and satisfaction with their treatment. METHODS: This cross-sectional, multicentre, observational study was conducted from April 2018 to September 2019 at six nationwide hospitals and three Korea Hemophilia Foundation clinics. Patients aged ≥16 years, or legal caregivers of paediatric patients, who had used factor VIII (FVIII) concentrates for ≥1 month were enrolled. Satisfaction with treatment was measured using the Treatment Satisfaction Questionnaire for Medication (TSQM); preference was evaluated using discrete choice experiment (DCE), with 10 series of two hypothetical treatment options created from D-efficient block design, which varied across five attributes. RESULTS: Overall, 505 patients (mean age 31 years) were enrolled in the study. Patients had received FVIII concentrate for an average of 102.9 months (prophylaxis: 53.5%; on-demand: 22.2%). Mean TSQM scores were 64.6 (effectiveness domain), 97.9 (side effects), 57.1 (convenience) and 66.8 (global satisfaction). The number of vials per injection, and the frequency of drug administration, was significantly associated with treatment satisfaction. According to DCE, simpler treatment options were preferred by patients/caregivers. CONCLUSION: The lowest satisfaction levels were shown in the treatment convenience domain. Patients/parents preferred simpler and easier treatment characteristics. In an attempt to enhance the overall satisfaction of patients and caregivers with treatment, consideration of more convenient characteristics is required in future decisions regarding treatment selection.

ABSTRACT

A retrospective study was conducted to determine the mortality, causes and risk factors for death among HIV-infected patients receiving antiretroviral therapy (ART) in Korea. The outcomes were determined by time periods, during the first year of ART and during 1-5 yr after ART initiation, respectively. Patients lost to follow-up were traced to ascertain survival status. Among 327 patients initiating ART during 1998-2006, 68 patients (20.8%) died during 5-yr follow-up periods. Mortality rate per 100 person-years was 8.69 (95% confidence interval, 5.68-12.73) during the first year of ART, which was higher than 4.13 (95% confidence interval, 2.98-5.59) during 1-5 yr after ART. Tuberculosis was the most common cause of death in both periods (30.8% within the first year of ART and 16.7% during 1-5 yr after ART). During the first year of ART, clinical category B and C at ART initiation, and underlying malignancy were significant risk factors for mortality. Between 1 and 5 yr after ART initiation, CD4 cell count ≤ 50 cells/µL at ART initiation, hepatitis B virus co-infection, and visit constancy ≤ 50% were significant risk factors for death. This suggests that different strategies to reduce mortality according to the time period after ART initiation are needed.

ABSTRACT

Although a decrease in acquired immunodeficiency syndrome (AIDS)-related mortality has been documented in highly active antiretroviral therapy (HAART) era, there are no published data comparing specific causes of death between pre-HAART and HAART era in Korea. Mortality and cause of death were analyzed in three treatment periods; pre-HAART (1990-1997), early-HAART (1998-2001), and late-HAART period (2002-2011). The patients were retrospectively classified according to the treatment period in which they were recruited. Although mortality rate per 100 person-year declined from 8.7 in pre-HAART to 4.9 in late-HAART period, the proportion of deaths within 3 months of initial visit to study hospital significantly increased from 15.9% in pre-HAART to 55.1% in late-HAART period (P < 0.001). Overall, 59% of deaths were attributable to AIDS-related conditions, and Pneumocystis pneumonia (PCP) was the most common cause of death (20.3%). The proportion of PCP as cause of death significantly increased from 8.7% in pre-HAART to 31.8% in late-HAART period (P < 0.001). Despite of significant improvement of survival, there was still a high risk of early death in patients presenting in HAART era, mainly due to late human immunodeficiency virus (HIV) diagnosis and late presentation to care.

ABSTRACT

This study compared the results of allogeneic peripheral blood stem cell transplantation (PBSCT) from unrelated and related donors in 142 consecutive patients with acute myeloid leukemia (AML). The cumulative incidence of acute graft-versus-host disease (GVHD) was 37.6% in the related PBSCT group and 53.7% in the unrelated PBSCT group. The cumulative incidence of extensive chronic GVHD was also higher in the unrelated PBSCT group (19.5%) than in the related PBSCT group (8.9%). The overall survival rate at 4 years was 62.4 ± 5.4 and 53.8 ± 1.2% (p = 0.535) in the related and unrelated PBSCT group, respectively. In a multivariate analysis, unrelated PBSCT was identified as a risk factor for the development of extensive chronic GVHD (hazard ratio = 3.019, p = 0.027). Unfavorable cytogenetics and the disease status at the time of transplantation were found to be related to overall survival. In the case of high-risk AML, the survival rate and relapse incidence were significantly better in the matched unrelated PBSCT group (p = 0.047 and 0.039, respectively). In conclusion, the allogeneic PBSCT outcomes for AML were comparable in the matched related and matched unrelated groups. Nonetheless, for high-risk AML patients, matched unrelated PBSCT was found to be preferable to matched related PBSCT.

ABSTRACT

In several studies of primary central nervous system lymphoma (PCNSL), deep-site involvement of the brain, as well as age and performance status (PS), were found to be independent prognostic factors. In immunocompetent patients, most primary central nervous system lymphomas (PCNSL) are diffuse large B-cell lymphomas (DLBCL), and recent studies have shown that Bcl-6 would be a favorable prognostic biomarker in PCNS-DLBCL. The objective of this study is to evaluate the clinical importance of the central nervous system (CNS) involvement pattern combined with Bcl-6 expression in PCNS-DLBCL patients. This study included 65 immunocompetent patients with PCNS-DLBCL who underwent treatment with high-dose methotrexate with whole-brain radiotherapy. Immunochemistry was performed for the Bcl-6 and Ki-67 antigens. Forty-four patients were male and 21 patients were female, with median age of 59 years. During the median follow-up period of 26 months, progression-free survival (PFS) was 25% and overall survival (OS) was 31%. Of 65 cases that could be subclassified, 31 patients were Bcl-6 positive and 34 patients were negative. Deep-site involvement of the brain was observed in 31 patients. The Bcl-6-positive group and the group having non-deep-site involvement of the brain were associated with favorable progression-free survival (PFS) (P < 0.001; P < 0.001) and overall survival (OS) (P = 0.001; P < 0.001). Results of univariate analysis showed that age above 60 years, Eastern Cooperative Oncology Group (ECOG) PS above 2, elevated lactate dehydrogenase (LDH) state, complete response (CR), and Bcl-6-positive and deep-site involvement were prognostic factors associated with PFS and OS. Results of multivariate analysis revealed that age above 60 years, ECOG above 2, elevated LDH state, Bcl-6 positivity, and deep-site involvement were independent prognostic factors for prediction of outcome. According to the combined prognostic value of Bcl-6 expression and the deep-site involvement pattern, the subgroup having Bcl-6-positive non-deep-site involvement of the brain showed more favorable PFS and OS than the other subgroups (P < 0.001, P < 0.001), whereas differences of survival among the other three subgroups were not significant (P = 0.054, P = 0.056). Bcl-6 positivity was found to be an independent prognostic factor for survival. Bcl-6 expression was associated with higher PFS and OS in patients having non-deep-site involvement. However, this was counteracted in the group of patients having deep-site involvement of the brain.

ABSTRACT

Although numerous studies about primary extranodal diffuse large B cell lymphoma (DLBCL) were reported sporadically, the literature of clinical value of immunophenotype and bulky diameter in rituximab era is limited. Ninety-six patients with primary extranodal DLBCL receiving R-CHOP therapy were analyzed to evaluate whether immunophenotype and size of bulky disease are significantly important. The International Prognostic Index was still an important prognostic factor for progression-free survival (PFS) and overall survival (OS; p = 0.003, p = 0.027). Difference of survival between germinal center (GC) type and non-GC type was not different (PFS: p = 0.192; OS: p = 0.197). In two separated groups according to extranodal maximum tumor diameter (EN-MTD) 7.5 cm as cutoff value for survival, the group of EN-MTD > or =7.5 cm had lower PFS and OS than <7.5 cm (PFS: p = 0.001; OS: p = 0.008). In four divided subgroups according to EN-MTD combined with immunophenotype, the subgroup of non-GC type with EN-MTD > or = 7.5 cm had lower PFS and OS compared with the other subgroups (PFS: p < 0.001; OS: p = 0.008). Multivariate analysis revealed that non-GC with EN-MTD > or = 7.5 cm was an independent prognostic parameter (PFS: HR = 5.407, 95%CI = 2.378-12.294, p < 0.001; OS: HR = 4.136, 95%CI = 1.721-9.941, p = 0.002). Bulky primary extranodal DLBCL would be associated with unfavorable outcome especially in non-GC type.

ABSTRACT

This study compared the results of allogeneic peripheral blood stem cell transplantation (PBSCT) from unrelated and related donors, and involved 235 consecutive patients from ten centers between Jan 2004 and Dec 2008. Among these patients, 160 (68.1%) received a human leukocyte antigen-matched related PBSCT and 75 (31.9%), a matched unrelated PBSCT. The cumulative incidence of acute graft-versus-host disease (GVHD) was 43.9% for the related PBSCT and 59.3% for the unrelated PBSCT. Although the cumulative incidence of chronic GVHD was no different between the related (54.2%) and unrelated (64.9%) PBSCT, the cumulative incidence of extensive chronic GVHD was higher among the unrelated PBSCT (34.9%) than among the related PBSCT (17.0%). The overall survival rate at 4 years was 58.2% versus 49.1%, and the cumulative incidence of relapse was 28.4% versus 25.0% for the related and unrelated PBSCT, respectively. Among the factors examined, unrelated PBSCT, the CD34-positive cell count, and cytomegalovirus infection were all related with a higher incidence of extensive chronic GVHD. However, in a multivariate analysis, only unrelated PBSCT was identified as a risk factor for the development of extensive chronic GVHD (hazard ratio = 2.012; P value, 0.048). In conclusion, the survival and relapse incidence were not significantly different between the related and unrelated PBSCT.

ABSTRACT

PURPOSE: To evaluate the prognostic value of the metabolic tumor volume measured on 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) imaging and other clinical factors in patients treated for locally advanced head-and-neck cancer (HNC) at a single institution. MATERIALS AND METHODS: Between June 2005 and August 2008, 59 patients with HNC that underwent pretreatment FDG-PET studies received neoadjuvant chemotherapy and radiation therapy. Metabolically active tumor regions were delineated on the pretreatment PET scans by a fixed SUV of 2.5. We evaluated the relationship of the 18F-fluorodeoxyglucose-PET maximum standardized uptake value (SUV) and the metabolic tumor volume (MTV) with the progression-free survival (PFS) and overall survival (OS). RESULTS: The MTV and lymph node metastasis were predictive of the PFS and OS. The lymph node status did not correlate with the MTV. A higher MTV of 9.3 cm(3) was significantly associated with an increased risk of recurrence (2.19-fold, p = 0.006) and death (1.62-fold, p = 0.051). Separation of patients with tumor volumes

ABSTRACT

A high absolute lymphocyte count (ALC) at diagnosis is known as a surrogate marker of favorable prognosis in newly diagnosed multiple myeloma (MM). Recent studies showed tumor sensitization and enhanced cytotoxicity of bortezomib. We hypothesized that a high ALC before bortezomib treatment would contribute to tumor sensitization and activated cytotoxicity of bortezomib in relapsed MM. Ninety-seven relapsed MM patients who underwent bortezomib-dexamethasone (Vel-Dex) therapy were analyzed. Median follow-up duration was 21 months and median age was 61 years. Complete response (CR) and very good partial response (VGPR) after 2 cycles of Vel-Dex therapy were higher in the high-ALC group (>or=1.1 x 10(9)/l) (CR + VGPR 50.0% in the high-ALC group vs. 10.4% in the low-ALC group, p = 0.001), and stable disease (SD) rate was lower in the high-ALC group (SD 11.8% in the high-ALC group vs. 44.8% in the low-ALC group, p < 0.001). In the univariate analysis, the low-ALC group before therapy was associated with shorter progression-free survival (PFS) [hazard ratio (HR), 2.780; 95% confidence interval (95% CI) 1.703-4.536, p < 0.001]. Multivariate analysis revealed that a low ALC represented an independent predictive factor for PFS (HR 1.937, 95% CI 1.168-3.212, p = 0.010). A low ALC just before Vel-Dex therapy was associated with a poor prognosis in relapsed MM.

ABSTRACT

BACKGROUND: The principal objective of this study was to assess clinical outcomes by breast cancer subtype in patients with brain metastases. METHODS: Estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 (HER2) status was evaluated via immunohistochemical staining. Four survival time intervals were compared according to the subtype (ER+/HER2-, HER2+, triple negative (TN)). RESULTS: 20 (30.3%) of the 66 patients in this study were ER+/HER2-, 20 (30.3%) were HER2+, and 26 (39.4%) were TN. The disease-free survival rates of ER+/HER2-, HER2+, and TN patients were 30.0, 17.0, and 17.9 months, respectively (p = 0.040). The median time intervals from distant metastasis to brain metastasis were 20.6, 19.5, and 9.0 months, respectively (p = 0.012). The times from initial diagnosis to brain metastasis were 52.9, 33.6, and 25.5 months, respectively (p = 0.026). However, the overall survival rates did not differ significantly (p = 0.276). CONCLUSIONS: Patients with TN breast cancer were more likely to develop distant metastasis earlier, and also evidenced poor overall survival. Triple receptor status may be employed as a prognostic marker for breast cancer patients with brain metastases.

ABSTRACT

Immunosuppressive therapy (IST) has provided an alternative treatment option for cure of aplastic anemia patients who cannot receive bone marrow transplantation. Although there have been many recent studies on the efficacy of antithymoglobulin (ATG) combined with cyclosporine A (CsA), there is no data on the correlation between the variability of CsA levels and the response to IST. Therefore, we retrospectively assessed the factors associated with IST efficacy in patients with acquired severe aplastic anemia (SAA). Sixty-six patients were treated with ATG combined with CsA for 6 months. In the response group, the CsA levels were increased rapidly to more than 200 ng/mL within the first 2 wk after starting the IST. However, the non-response group had a pattern of slower increase of the CsA levels. The CsA levels, during the first and second week of treatment with IST, were significantly different in the responders and non-responders. The factors predictive of response to IST and survival were analyzed. The univariate analysis showed that a younger age at the initiation of IST, a high absolute neutrophil count prior to starting IST, a short interval between the diagnosis and initiation of IST, and high CsA levels during the first and second week of IST treatment were positively associated with the response rate and overall survival. The multivariate analysis showed that these four factors were independent factors associated with a longer patient survival. A high response rate was associated with a short interval between diagnosis and initiation of IST as well as high CsA levels during the first and second week of IST. Therefore, early intensification of CsA levels might improve patient outcome.

ABSTRACT

BACKGROUND: This study aimed to evaluate the safety and efficacy of oral fluoropyrimidines and cisplatin therapy in elderly patients with untreated advanced gastric cancer (AGC) retrospectively. In addition, we evaluated the relative activity and toxicity of these agents in this patient population. METHODS: Clinical data from 72 patients with previously untreated AGC, who were treated with capecitabine/cisplatin and S-1/cisplatin, were reviewed. Oral fluoropyrimidines were administered orally twice a day on Days 1-14. The dose of capecitabine was 1250 mg/m(2) and that of S-1 was 50 mg [body surface area (BSA) < 1.5 m(3)] or 60 mg (BSA > 1.5 m(3)) twice a day. Cisplatin was administered intravenously on Day 1 (before the first dose of capecitabine or S-1) at a dose of 70 mg/m(2) over a 2 h period. The chemotherapy cycle was of 3 weeks (with oral capecitabine or S-1). RESULTS: Thirty-two and 40 patients received the S-1 and capecitabine regimens, respectively, and were included in the analysis. The S-1 protocol had a response rate of 40.6%, a median time-to-progression (TTP) of 5.4 months and a median survival of 9.6 months. The capecitabine had a response rate of 55%, a median TTP of 5.9 months and a median survival of 10.2 months. Each protocol had a similar incidence of Grade 3 or 4 adverse events. However, there was a higher rate of the hand-foot syndrome (6 versus 37%) and diarrhea (25 versus 32%) in the capecitabine group. CONCLUSION: Oral fluoropyrimidines and cisplatin in elderly patients with untreated AGC showed encouraging results. The treatment was well tolerated with a manageable toxicity profile. The comparison of S-1 with capecitabine showed that capecitabine had a slightly higher response rate (statistically not significant) in addition to a higher rate of adverse events such as the hand-foot syndrome and diarrhea. These data should be warranted with further prospective studies.

ABSTRACT

Previous reports have suggested that a high serum cyclosporine A (CsA) level could result in a lower incidence of acute-graft-versus-host disease (aGVHD). An elevated serum lactate dehydrogenase (LDH) level has been reported to be an adverse predictor of outcome in stem cell transplantation (SCT) for acute myeloid leukemia. In this study, we retrospectively analyzed the records of 24 patients who received allogeneic SCT from an HLA-matched sibling donor for acute and chronic myelogenous leukemia. Univariate analysis showed that two factors (the serum CsA level at the third week after SCT and the LDH level at the third week after SCT) were significantly associated with the incidence of aGVHD among several variables (age, sex, stem cell source, cell dose, C-reactive protein, absolute lymphocyte count, conditioning regimens, and time to engraftment). A higher serum level of CsA and lower serum LDH level at the third week after SCT were associated with a lower incidence of aGVHD (P=0.015, 0.030). In multivariate analysis, the serum CsA level (hazard ratio [HR], 0.12; 95% confidence interval [CI], 0.022-0.652, P=0.0014) and serum LDH level (HR, 6.59; 95% CI, 1.197-36.316, P=0.030) at the third week after SCT were found to be independent factors that were significantly associated with the development of aGVHD. We conclude that a high CsA level and low LDH level might predict a low cumulative incidence of aGVHD after allogeneic transplantation from a matched sibling donor.

ABSTRACT

We studied the incidence of cytomegalovirus (CMV) infection, clinical outcomes, and complications in 39 recipients of alemtuzumab-containing conditioning-stem cell transplantation, who were classified into two groups based on the median dose (35 mg) of alemtuzumab. All the recipients and donors were CMV-seropositive before transplantation. The median survival duration was 321 days (range, 46-1098 days) and the 2-year survival rate was 47.8%. The probability of nonrelapse mortality at 100 days and 2 years was 14.6% and 31.2%, respectively. The cumulative incidence of Grade II-IV acute graft-versus-host disease (GVHD) at Day 100 was 21.8%. The overall incidence of chronic GVHD (cGVHD) was 28.6%, including a 17.9% incidence of extensive cGVHD. The cumulative incidence of CMV antigenemia was 68.0%. There were no statistical differences in the engraftment, acute and cGVHD, relapse, CMV antigenemia, and overall survival (OS) between the two groups. Yet, the nonrelapse mortality (NRM) was significantly lower for the low-dose group (5.9% vs. 51.7%, P = 0.010). The present study showed that alemtuzumab was effective for GVHD prevention, yet caused a relatively high incidence of CMV antigenemia, regardless of the dose. Thus, a low dose of alemtuzumab (< or = 35 mg) would seem to be preferable in an allogeneic SCT setting when both the recipient and the donor are CMV seropositive.

ABSTRACT

BACKGROUND: The prevalence of AIDS-related lymphoma (ARL) is increasing in South Korea. The aim of this study is to identify the clinical features of ARL in South Korea. METHODS: From 1998 through 2006, we retrospectively analysed a total of 23 cases of ARL from seven institutions. RESULTS: The patients consisted of 20 males and 3 females at a median age of 40 (range, 20-72) on diagnosis of AIDS. ARL developed at their median age of 41 (range, 24-72). The histological diagnosis was aggressive B cell lymphoma in the majority, but rare T cell and NK/T cell lymphoma were also included. Ten of 23 (43.5%) was receiving highly active anti-retroviral therapy (HAART) before the diagnosis of ARL. Fifteen of twenty-three patients were given combination chemotherapy with/without radiation, four were given radiation alone, and four did not receive any treatment against medical advice. Of 20 patients followed-up, nine were alive in remission, two alive in disease, one died of treatment related complication, four died of progressive lymphoma, four died of AIDS related causes. The response to treatment included CR in eight (44.4%), PR in four (22.2%) and PD in three (16.7%). The response to HARRT was evaluable in 13 patients based on CD4+ cell count and HIV viral load, among which nine (69.2%) responded. Estimated median survival time was 43.9 months. CONCLUSIONS: Although the population of patients is small, this is the first clinical data analyses of Korean ARL patients. As a substantial portion of the patients remains alive disease free, the impact of HAART on the clinical course of ARL needs further follow-up and evaluation.

ABSTRACT

PURPOSE: The present study was conducted to evaluate the safety and efficacy of alemtuzumab plus CHOP chemotherapy for patients with peripheral T-cell lymphomas (PTCLs). PATIENTS AND METHODS: Twenty patients with newly diagnosed PTCLs were enrolled. The treatment consisted of classical CHOP plus alemtuzumab (10 mg i.v. on day 1 and 20 mg i.v. on day 2 in the first cycle, then 30 mg i.v. on day 1 in the subsequent cycles) based on 3-week intervals. RESULTS: Thirteen complete responses (65.0%) and three partial responses (15.0%) were confirmed, giving an overall response rate of 80.0%. The estimated event-free survival at 1 year was 43.3%. The most severe hematologic adverse event was neutropenia, which occurred with a grade-4 intensity in 18 patients (90.0%). Also, febrile neutropenia was observed in 11 patients (55.0%). Five patients (25%) experienced cytomegalovirus (CMV) reactivation, while three patients developed CMV diseases, such as pneumonitis or retinitis. There were two treatment-related deaths. Based on the high incidence of the adverse infectious and hematologic events, the current study was closed after 20 of the planned 43 patients had been enrolled. CONCLUSION: The alemtuzumab plus CHOP chemotherapy seemed to produce active antitumor activity in terms of the complete response rates in patients with PTCLs. However, since high infectious and hematologic toxicities were observed, careful monitoring and early treatment are needed to prevent treatment-related mortality.

ABSTRACT

PURPOSE: Since a weekly administration of paclitaxel has demonstrated a sustained efficacy and more favorable toxicity profile than a 3-weekly administration for various solid tumors, the present study was conducted to evaluate the efficacy and safety of a combination regimen of weekly paclitaxel plus cisplatin in patients with advanced gastric cancer. PATIENTS AND METHODS: Patients with previously untreated metastatic or recurrent, measurable gastric cancer received intravenous paclitaxel 100 mg/m(2) plus cisplatin 35 mg/m(2) on days 1 and 8 based on a 3-week cycle. RESULTS: Fifty-two patients were enrolled in the current study. Two complete responses and 17 partial responses were confirmed, giving an overall response rate of 36.5%. At a median follow-up of 8.5 months, the median time to progression and median overall survival was 6.0 and 10.8 months, respectively. Grade 3 neutropenia occurred in ten patients, while no grade 4 neutropenia or febrile neutropenia was observed. The most common non-hematologic toxicity was nausea (grade 1/2, 56.9%). There were no treatment-related deaths. CONCLUSION: A weekly paclitaxel and cisplatin combination was found to be well-tolerated and effective in patients with advanced gastric cancer. Accordingly, this regimen can be regarded as an important first-line treatment option for advanced gastric cancer.

ABSTRACT

Appropriate pain assessment is very important for managing cancer pain. This study was designed to evaluate the utility of the Korean Cancer Pain Assessment Tool (KCPAT) by assessing changes in the management of cancer pain. The changes in pain intensity, the pattern of drug prescriptions, and the patients' satisfaction with pain control were analyzed after using the KCPAT. The results indicated that pain medicine prescriptions were changed in 194 (51.5%) cases after using the KCPAT, and 69.5% of these changes were affected by the KCPAT. After using the KCPAT, pain intensity as assessed by the Visual Analogue Scale (VAS, 0-10cm) decreased (4.31+/-2.35 vs. 3.60+/-2.45, P<0.0001), and the presence of associated symptoms and psychosocial items was significantly reduced. The patients' satisfaction with pain control was improved. Forty-four physicians (89.8%) thought that the KCPAT was useful. The KCPAT improved patients' satisfaction with pain control and was a useful tool for evaluating and managing cancer pain.

ABSTRACT

Acute promyelocytic leukemia (APL) is characterized by a serious hemorrhagic syndrome, unique morphologic findings, and its response to retinoids. Tetraploidy is a very rare chromosomal abnormality in acute myelocytic leukemia. This report presents a unique case of APL with a tetraploid clone characterized by two t(15;17) without other chromosomal changes, as well as PML/RARA rearrangements confirmed fluorescence in situ hybridization. The morphology of the blast cells was that of the classic M3 subtype, but the mean blast size exceeded that of control APL cases with diploidy. A chromosomal study revealed a 92,XXXX,t(15;17)(q22;q21)x2 karyotype in all 20 metaphase spreads. Despite all-trans-retinoic acid (ATRA) treatment and chemotherapy, leukemic cells persisted in the blood, and the patient died of an intracranial hemorrhage on the 16th day after admission.
