Purpose The Korean Society of Pediatric Neuro-Oncology (KSPNO) conducted treatment strategies for children with medulloblastoma (MB) by using alkylating agents for maintenance chemotherapy or tandem high-dose chemotherapy (HDC) with autologous stem cell rescue (ASCR) according to the risk stratification. The purpose of the study was to assess treatment outcomes and complications based on risk-adapted treatment and HDC.
Materials and Methods Fifty-nine patients diagnosed with MB were enrolled in this study. Patients in the standard-risk (SR) group received radiotherapy (RT) after surgery and chemotherapy using the KSPNO M051 regimen. Patients in the high-risk (HR) group received two and four chemotherapy cycles according to the KSPNO S081 protocol before and after reduced RT for age following surgery and two cycles of tandem HDC with ASCR consolidation treatment.
Results In the SR group, 24 patients showed 5-year event-free survival (EFS) and overall survival (OS) estimates of 86.7% (95% confidence interval [CI], 73.6 to 100) and 95.8% (95% CI, 88.2 to 100), respectively. In the HR group, more infectious complications and mortality occurred during the second HDC than during the first. In the HR group, the 5-year EFS and OS estimates were 65.5% (95% CI, 51.4 to 83.4) and 72.3% (95% CI, 58.4 to 89.6), respectively.
Conclusion High intensity of alkylating agents for SR resulted in similar outcomes but with a high incidence of hematologic toxicity. Tandem HDC with ASCR for HR induced favorable EFS and OS estimates compared to those reported previously. However, infectious complications and treatment-related mortalities suggest that a reduced chemotherapy dose is necessary, especially for the second HDC.
Purpose This study aimed to explore the impact of ABL1–tyrosine kinase inhibitors (TKIs) adherence on the survival of chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL) children and clarify the potential predictors of patients’ prognosis from TKIs intake practices.
Materials and Methods Ninety newly diagnosed Ph+ ALL patients who received TKIs were enrolled. We collected the baseline characteristics and adverse events in all children; moreover, TKIs adherence was measured by an eight-item Morisky medication adherence scale (MMAS-8). Progression-free survival (PFS) and overall survival (OS) analysis were performed, and risk factors for PFS and OS were evaluated.
Results Among all patients, 69 cases were regarded as adherers, while 21 were non-adherers. The median duration of TKIs interruption was significantly prolonged in the non-adherence group than in the adherence group (13 [0-101] vs. 56 [11-128], p < 0.001). Additionally, dose reduction occurred in 55.2% of non-adherers versus 23.0% of adherers (p=0.002). The PFS and OS in adherers were significantly higher versus non-adherers (p=0.020 and p=0.039). MMAS-8 score was an independent risk factor for PFS (p=0.010) and OS (p=0.031). Among non-adherers, the median OS was only 23.1% (4.2%-42%) in patients aged ≤ 10 years versus 54.4% (38.8%-70%) in adolescents. Most of the patients who experienced TKIs non-adherence suffered pancytopenia.
Conclusion TKIs adherence during treatment significantly influenced the survival of pediatric Ph+ ALL patients, and non-adherers with age ≤ 10 years were more vulnerable to TKIs disruption. The cumulative TKIs dose should be especially emphasized to patients with age ≤ 10 years, which may result in an inferior achievement of relevant treatment milestones.
Purpose Approximately 30%-40% of pediatric acute myeloid leukemia (AML) patients relapse. In this study, we analyzed the outcome and prognostic factors of relapsed AML patients who had previously received first-line therapy at our institution.
Materials and Methods The study group consisted of 50 patients who had been diagnosed with AML from April 2009 to December 2018, and then showed first relapse. Thirty-two of the patients (64%) had previously received allogeneic hematopoietic stem cell transplantation (HSCT) in first complete remission (CR).
Results Forty-five of the patients (90%) received intensive chemotherapy upon diagnosis of relapse, and 76% (34/45) of these patients achieved a second CR. Estimated 5-year overall survival for these 45 patients was 44.9%±7.6%. Time from diagnosis to relapse, extramedullary involvement (EMI) at diagnosis, core binding factor AML, and complex karyotype were significant prognostic factors; in multivariate study, both time from diagnosis to relapse and EMI at diagnosis proved significant. There was no difference in 5-year disease-free survival between patients previously treated with chemotherapy only and those who received HSCT in first CR (52.4%±14.9% vs. 52.6%±11.5%). Of the 19 patients who achieved second CR after previous allogeneic HSCT in first CR and subsequent relapse, 11 were treated with chemotherapy only, and seven survive disease-free.
Conclusion Intensive therapy allowed for long-term survival in 40%-50% of patients, and 50% of patients who achieved second CR, regardless of prior treatment modalities in first CR. Intensive treatment may allow for salvage of a significant portion of patients with relapsed pediatric AML.

Purpose Atypical teratoid/rhabdoid tumor (ATRT) is a highly aggressive malignancy with peak incidence in children aged less than 3 years. Standard treatment for central nervous system ATRT in children under the age of 3 years have not been established yet. The objective of this study was to analyze characteristics and clinical outcomes of ATRT in children aged less than 3 years.
Materials and Methods A search of medical records from seven centers was performed between January 2005 and December 2016.
Results Forty-three patients were enrolled. With a median follow-up of 90 months, 27 patients (64.3%) showed at least one episode of disease progression (PD). The first date of PD was at 160 days after diagnosis. The 1- and 3-year progression-free survivals (PFS) were 51.2% and 28.5%, respectively. The 1- and 3-year overall survivals were 61.9% and 38.1%, respectively. The 3-year PFS was improved from 0% in pre-2011 to 47.4% in post-2011. Excluding one patient who did not receive any further therapy after surgery, 27 patients died due to PD (n=21), treatment-related toxicity (n=5), or unknown cause (n=1). In univariate analysis, factors associated with higher 3-year PFS were no metastases, diagnosis after 2011, early adjuvant radiotherapy, and high-dose chemotherapy (HDCT). In multivariate analysis, the use of HDCT and adjuvant radiotherapy remained significant prognostic factors for PFS (both p < 0.01).
Conclusion Aggressive therapy including early adjuvant radiotherapy and HDCT could be considered to improve outcomes of ATRT in children under the age of 3 years.

Purpose
We sought to investigate the effectiveness and safety of dabrafenib in children with BRAFV600E-mutated Langerhans cell histiocytosis (LCH).
Materials and Methods
A retrospective analysis was performed on 20 children with BRAFV600E-mutated LCH who were treated with dabrafenib.
Results
The median age at which the patients started taking dabrafenib was 2.3 years old (range, 0.6 to 6.5 years). The ratio of boys to girls was 2.3:1. The median follow-up time was 30.8 months (range, 18.9 to 43.6 months). There were 14 patients (70%) in the risk organ (RO)+ group and six patients (30%) in the RO– group. All patients were initially treated with traditional chemotherapy and then shifted to targeted therapy due to poor control of LCH or intolerance to chemotherapy. The overall objective response rate and the overall disease control rate were 65% and 75%, respectively. During treatment, circulating levels of cell-free BRAFV600E (cfBRAFV600E) became negative in 60% of the patients within a median period of 3.0 months (range, 1.0 to 9.0 months). Grade 2 or 3 adverse effects occurred in five patients.
Conclusion
Some children with BRAFV600E-mutated LCH may benefit from monotherapy with dabrafenib, especially high-risk patients with concomitant hemophagocytic lymphohistiocytosis and intolerance to chemotherapy. The safety of dabrafenib is notable. A prospective study with a larger sample size is required to determine the optimal dosage and treatment duration.

Purpose
Neuroblastoma (NB) is the most common extracranial solid tumor found in children. To identify significant genetic factors for the risk of NB, several genetic studies was conducted mainly for Caucasians and Europeans. However, considering racial differences, there is a possibility that genetic predispositions that contribute to the development of NB are different, and GWAS study has not yet been conducted on Korean NB patients.
Materials and Methods
To identify the genetic variations associated with the risk of pediatric NB in Korean children, we performed a genome-wide association analysis with 296 NB patients and 1000 unaffected controls (total n = 1,296) after data cleaning and filtering as well as imputation of non-genotyped SNPs using IMPUTE v2.3.2.
Results
After adjusting for multiple comparisons, we found 21 statistically significant SNPs associated with the risk of NB (Pcorr < 0.05) within 12 genes (RPTN, MRPS18B, LRRC45, KANSL1L, ARHGEF40, IL15RA, L1TD1, ANO7, LAMA5, OR7G2, SALL4, and NEUROG2). Interestingly, out of these, 12 markers were nonsynonymous SNPs. The SNP rs76015112 was most significantly associated with the risk of NB (p = 8.1E-23, Pcorr = 2.3E-17) and was located in the RPTN gene. In addition, significant nonsynonymous SNPs in ADGRE1 were found in patients with MYCN amplification (rs7256147, p = 2.6E-05). In high-risk group, rs7256147 was observed as a significant SNP (p = 5.9E-06).
Conclusion
Our findings might facilitate improved understanding of the mechanism of pediatric NB pathogenesis. However, functional evaluation and replication of these results in other populations are still needed.

Purpose
The purpose of this study was to evaluate the long-term clinical outcome and toxicity of induction chemotherapy (IC) followed by concomitant chemoradiotherapy (CCRT) compared with CCRT alone for the treatment of children and adolescent locoregionally advanced nasopharyngeal carcinoma (LACANPC).
Materials and Methods
A total of 194 locoregionally advanced nasopharyngeal carcinoma patients youngerthan 21 years who received CCRT with or without IC before were included in the study population. Overall survival (OS) rate, progression-free survival (PFS) rate, locoregional recurrence-free survival (LRFS) rate, and distant metastasis-free survival (DMFS) rate were assessed by the Kaplan-Meier method and a log-rank test. Treatment toxicities were clarified and compared between two groups.
Results
One hundred and thiry of 194 patients received IC+CCRT. Patients who were younger and with more advanced TNM stage were more likely to receive IC+CCRT and intensive modulated radiotherapy. The addition of IC before CCRT failed to improve survival significantly. The matched analysis identified 43 well-balanced patients in both two groups. With a median follow-up of 51.5 months, no differences were found between the IC+CCRT group and the CCRT group in 5-year OS (83.7% vs. 74.6%, p=0.153), PFS (79.2% vs. 73.4%, p=0.355), LRFS (97.7% vs. 88.2%, p=0.083), and DMFS (81.6% vs. 81.6%, p=0.860). N3 was an independent prognostic factor predicting poorer OS, PFS, and DMFS. The addition of IC was associated with increased rates of grade 3 to 4 neutropenia.
Conclusion
This study failed to demonstrate that adding IC before CCRT could provide a significant additional survival benefit for LACANPC patients. Further investigations are warranted.

At presentation, the patient had a 2.5cm sized mass on her left breast which was firmly attached to the overlying nipple. The aspiration cytologic findings of the tumor were consistent with a secretory carcinoma. After confirming malignancy by frozen section diagnosis, a modified radical mastectomy was performed and secretory carcinoma was finally diagnosed. To our knowledge, secretory breast carcinoma in children has not been reported previously in Korea and this seems to be the youngest case of secretory carcinoma of the breast which had been reported in English literature.
PURPOSE Myelodysplastic syndrome (MDS) in children needs to be elucidated in terms of clinical characteristics, natural history, the most effective treatment and prognostic factors, as the disease is very rare and its definition and classification has not reached a consensus by many physician.
This study was aimed to describe the characteristics and the disease courses of Korean children with MDS, and to analyze the usefulness of prognostic scoring systems in the prediction of transformation to acute myelogenous leukemia (AML) and overall survival among subgroups. MATERIALS AND METHODS Fourteen children with MDS seen at Chonnam University Hospital and additional 59 patients identified by the review of Korean literature were evaluated to define clinical characteristics and disease courses. Kaplan-Meier (K-M) probability of leukemic transformation and overall survival were plotted. FAB subtypes, subgroups by Boumemouth Scoring System (BSS), and International Prognostic Scoring System (IPSS) risk groups were compared to predict transformation to AML and overall survival. RESULTS The median age of 14 patients was 36.5 months. The sex ratio was 3.7:1 (M: F). The frequency of FAB subtypes in Korea was similar to that of other countries except for higher proportion of RA (37%). K-M 3-yr probability of AML transformation and survival for Korean patients were 54.7%, and 49.8%, respectively. Although FAB system, BMS and IPSS were all capable of discriminating subgroups in the prediction of AML transformation and survival, they did not reach the significant level possibly due to small number of patients assigned to each subgroup. CONCLUSION The clinical characteristics of Korean children with MDS were not different from those of other countries. This study showed the high rate of AML transformation and poor survival in children with MDS.
PURPOSE Pancreatic tumors are relatively rare in children.
Until now more than 150 cases have been reported in the English literature. In this paper, the authors report the tumors clinical characteristics and the results of surgery in eleven children. MATERIALS AND METHODS Eleven cases of pancreatic tumor pathologically verified at Seoul National University Children's Hospital between 1984 to 1998 were retrospectively analyzed. Four were boys and seven were girls, and their mean age at diagnosis was 7.7 (range, 2 13) years. RESULTS There were six solid and papillary epithelial neoplasms of the pancreas (SPENP) and five pancreatoblastomas. All children came to medical attention because of abdominal masses. Tumors ranged in size from 6.0X 5.0 cm to 10.5 x 8.0 cm. Eight tumors were located in head and three in tail. Complete excision was performed in eight cases (six in SPENP and two in pancreatoblastoma).
Incomplete excision was performed in two cases of pancreatoblastoma. One patient with pancreatoblastoma had an unresectable tumor at the time of diagnosis and needle aspiration biopsy was done under the ultrasound guidance. No patient died during surgery. After a mean follow-up period of 4.1 years, all patients with SPENP were alive and there had been no recurrence. However, of two patients who received complete excision in pancreatoblastoma, one presented with liver metastasis at 4 months after operation and received chemotherapy, but died 6 months after operation. The other patient had local recurrence 1 year after operation. Reoperation and chemotherapy were performed and the child is now alive without evidence of disease montbs after the initial operation. All three patients with unresectable tumor died in spite of adjuvant radiotherapy and chemotherapy. CONCLUSION Pediatric pancreatic tumors comprise rare heterogenous groups of malignancies with their prognosis dependent upon adequate resection and pathologic classification. Complete resection of pancreatic tumors arising anywhere in the pancreas was recommended.
