OBJECTIVETo evaluate the sensitivity of NT-pro-BNP in daunorubicin (DNR) induced myocardial damage by monitoring the level of NT-pro-BNP and myocardial enzymes (CK, CKMB) before and after DNR treatment in childhood acute leukemia (AL) and performing control study.

METHODSSixty-two cases (total 194 samples) which diagnosed as primary AL were enrolled and had received the conventional chemotherapy. According to the cumulative dose of DNR, they were divided into three groups: cumulative dose ≤ 60 mg/m(2) (group A); cumulative dose 60 - 120 mg/m(2) (group B); cumulative dose > 120 mg/m(2) (group C) and 15 cases with idarubicin (IDA) or mitoxantrone (MXR) as altervative to DNR (group D).

RESULTSThere was a significant difference (P = 0.000) in the level of NT-pro-BNP before and after DNR therapy, but did not in the myocardial enzymes activities (CK, P = 0.085 and CKMB, P = 0.076). The level of NT-pro-BNP appeared obviously elevated (P = 0.001) when DNR cumulative dose > 60 mg/m(2). While the level of CKMB did (P = 0.022) until DNR cumulative dose > 120 mg/m(2). In the 15 cases used IDA or MXR as alternative to DNR, the level of NT-pro-BNP fall from (239.9 ± 230.0) ng/L to (137.0 ± 131.9) ng/L (P = 0.024).

CONCLUSION(1) Compared with myocardial enzymes detection, NT-pro-BNP level can predict earlier DNR-induced cardiotoxicity. (2) Selection of the second or third generation anthracycline to treat AL can significantly reduce the cardiotoxicity in children.

OBJECTIVETo compare the complete remission rate (CRR) and adverse reaction of the 3 different chemotherapy regimens (daunorubicin, idarubicin, imported idarubicin combined with cytarabine) for the treatment of adult patients with newly diagnosed non-M3 acute myeloid leukemia (AML).

METHODSSeventy-one adult patients with newly diagnosed non-M3 AML were divided into 3 groups: 17 cases treated with daunorubicin plus cytarabine as group A, 24 cases treated with idarubicin plus cytarabine as group B, 30 cases treated with the imported idarubicin plus cytarabine as group C. The curative effects and adverse reactions were compared among the 3 groups after treatment.

RESULTSCCR in group C (86.67%) was significantly higher than that in group A (52.94%) and group B (70.83%), and the CRR in group B was significantly higher than that in group A (P<0.05). The incidence of adverse reaction such as nausea, vomiting, myelosuppression and infection among 3 groups were not statistically significantant (P>0.05).

CONCLUSIONThe curative effect of idarubicin for the treatment of non-M3 AML patients is better than that of daunorubicin, especially the curative efficiency of imported darubicin is much higher; the adverse reaction after treatment by daunorubicin and idarubicin can be controllable, so daunorubicin and idarubicin can be used as first-line drug for the patients with AML, and patients can choose more appropriate drug according to their own economic ability.

BACKGROUND: Standard remission induction chemotherapy consisting of anthracycline plus cytarabine (3+7) is administered for adult acute myeloid leukemia (AML). However, the effects of intensified regimen on complete remission (CR), relapse and overall survival (OS) remain unknown. METHODS: We analyzed 1195 patients treated with idarubicin plus cytarabine/BHAC (3+7) from 2002 to 2013. Among them, 731 received early intensification with 3-day cytarabine/BHAC (3+10, N=363) or 2-day idarubicin plus cytarabine/BHAC 3 days (5+10, N=368). The 3+10 and 5+10 strategies were applied to patients with bone marrow blast counts of 5–20% and >20% on day 7 of 3+7, respectively. RESULTS: Early intensification correlated with a younger age (median: 40 vs. 45 yr) and higher t(8;21) frequency (20.4% vs. 7.1%), compared to 3+7. After early intensification, the early death rates were higher among the elderly (3+10 [15.7%], 5+10 [21.7%] vs. 3+7 [6.3%], P=0.038), while the post-induction CR rate was higher in young patients (3+10 [79.8%], 5+10 [75.1%] vs. 3+7 [65.1%], P<0.001). Early relapse rate was also decreased (3+10 [11.8%], 5+10 [11.7%] vs. 3+7 [22.0%], P<0.001). In multivariate analysis, early intensification correlated with an inferior 5-year OS among elderly patients (19.2% vs. 22.8%; hazard ratio [HR]=1.84, 95% confidence interval [CI]; 1.11–3.06, P=0.018) and lower overall relapse rate among young patients (33.0% vs. 41.4%, P=0.023; HR=0.71, 95% CI; 0.55–0.93, P=0.012). CONCLUSION: Early intensification correlated with higher CR and lower relapse rates, but not OS in young AML patients. In elderly patients, early intensification correlated with a higher early death rate and poorer OS.

PURPOSE: This study was conducted to determine the efficacy and safety of DA-3030 (a recombinant methionyl human granulocyte colony-stimulating factor, rhG-CSF), after remission induction chemotherapy, in patients with acute myelogenous leukemia (AML). MATERIALS AND METHODS: After the remission induction chemotherapy, with idarubicin (12 mg/m2/day for 3 days) and cytarabine (200 mg/m2/day for 7 days), 26 patients with newly diagnosed AML were assigned to receive DA-3030 (200mug/m2/day), starting 24 hours after the completion of the remission induction chemotherapy, until their neutrophil count recovered to greater than 1, 000/muL for 3 consecutive days. RESULTS: The median time from the initiation of the chemotherapy to the neutrophil recovery of 1, 000/muL was 21 days (range, 12~41). Treatment with DA-3030 was not associated with significant adverse side effects. The most frequently reported side effects were musculo-skeletal pain (13%) and headache (13%). CONCLUSION: The DA-3030 is a safe rhG-CSF for the treatment of neutropenia after remission induction chemotherapy in patients with AML.

BACKGROUND/AIMS: There are three types of PML-RAR alpha mRNA fusion transcripts associated with acute promyelocytic leukemia (APL): the short (S)-form, the long (L)-form and the variable (V)-form. No study on the Korean population has addressed the clinical significance of the specific types of PML-RAR alpha mRNA fusion transcripts for APL patients who receive the combination therapy of all-trans-retinoic-acid and idarubicin (AIDA regimen). METHODS: We performed a retrospective analysis on 94 patients with APL to evaluate differences in the therapeutic outcomes, such as the response rate, an event-free survival (EFS), and overall survival (OS), after remission following the induction of chemotherapy. We also analyzed whether differences in the pretreatment clinical characteristics depend on the PML-RAR alpha isoform. RESULTS: The median age of the patients was 41 years (range 15-85). Among the 94 patients, there were 58 L-form cases (62.1%), 32 S-form cases (34.0%), and 4 V-form cases (4.3%). The CR rate following remission induction treatment was 84.9%. The CR rate was higher in patients with an initial WBC <10.0x109/L, as compared to patients with an initial WBC higher than 10.0X109/L (93.5% vs. 65.4%, p=0.001). The AIDA induction regimen was associated with a better EFS than non-AIDA induction regimens (81.9% vs. 49.6%, p=0.006). The induction group was also a significant prognostic factor for EFS in the multivariate analysis (p=0.020). There were no differences in OS and EFS in patients with either isoform L or isoform S in the AIDA induction group. CONCLUSIONS: This retrospective study demonstrated that pretreatment clinical characteristics and treatment outcomes were not significantly different among patients with varying PML-RAR alpha isoform types in the AIDA induction group.

OBJECTIVETo compare the efficacy and toxicity of 10 mg/m² or 8 mg/m² idarubicin (Ida) combined with cytarabine (IA"3+7"regimen) as induction chemotherapy for adult patients with newly diagnosed acute myeloid leukemia (AML).

METHODSFrom June 2004 to October 2013, 335 adult AML (non acute promyelocytic leukemia) patients receiving the IA regimen as induction chemotherapy were enrolled, including 198 cases with 10 mg/m² Ida and 137 cases with 8 mg/m² Ida for 3 days. We compared the hematologic response, hematologic side effects and prognosis between the two regimens.

RESULTSExcept for 4 early deaths, the complete remission (CR) rate after the first cycle of induction chemotherapy was 72.5%, 10.0% partial remission (PR) and 82.5% overall remission (OR) rate. The CR and OR rates were higher in the 10 mg/m² Ida group than the 8 mg/m² Ida group (CR: 78.9% vs 63.5%, P=0.003; OR: 88.2% vs 75.4%, P=0.007). Multivariate analysis showed that female, HGB≥100 g/L, FLT3-ITD mutation negative and 10 mg/m² Ida were favorable factors for CR. All patients presented cytopenias of grade Ⅳ. There was no differences on the recovery time of ANC≥0.5×10⁹/L and PLT≥20×10⁹/L after induction chemotherapy. Within a median follow-up of 14 (1-118) months, 98 (29.3%) patients relapsed, 92 (27.5%) died. The disease-free survival (DFS) and overall survival (OS) at 3 years were 53.2% and 58.9%, respectively. DFS and OS at 3-year were 34.2% and 37.4% in the chemotherapy cohort, 74.5% and 81.2% in the transplant cohort. 10 mg/m² Ida was an independent favorite factor for DFS (P=0.040) and OS (P=0.007).

CONCLUSIONAs compared to 8 mg/m², 10 mg/m² Ida significantly improved the CR, with the same extent of hematological side effects, and was an independent favorite factor for DFS and OS.

BACKGROUND: Anthracycline is the most important chemotherapy drug of acute myelocytic leukemia (AML). It has been reported that idarubicin could have better complete remission (CR) rate than daunorubicin. However, it is not completely established concerning the effectiveness of idarubicin. There are many prognostic indicators of AML, however, many discrepancies still exist in prognostic indicators among each centers. METHODS: We analyzed initial CR rate of 39 AML patients treated with combination of cytarabine plus idarubicin or daunorubicin at Samsung Medical Center from April, 1995 to December, 1997. We subgrouped the patients according to age, sex, initial WBC count, status of initial CR, CD34, and chromosome. We analyzed the initial CR rate and long term survival of each subgroups. RESULTS: Initial CR rates of idarubicin and daunorubicin were 76.5% and 72.7%, respectively. The median survival days of 39 patients was 727+/-308.8 days. 1-year survival rate and 1-year event free survival rate were 64.2% and 59.6%, respectively. Patients who had failure of initial CR, old age (>60 years), and initial high WBC counts (>100,000/L) showed a statistically significant shorter survival in univariate analysis. However, we could not find the significant difference in the positivity of CD34 and chromosomal abnormalities. CONCLUSION: The effectiveness of idarubicin may be equivalent to that of daunorubicin. Failure of initial CR, old age, and high WBC counts were regarded as a prognostic risk factors of AML. However, a more definitive characterization of prognostic factors is warranted in further prospective study.
