Twenty-one gliomas in patients aged 0-21 years were evaluated for drug sensitivity by ex vivo expanded circulating tumor cells (CTC). The results were correlated with clinical outcomes. Venous blood samples were obtained prior to drug treatment. Peripheral blood mononuclear cells were processed in a 3D cell culture system (EVA Select™, Cancer Free...

Background: This study analyzed data from two consecutive protocols for children newly diagnosed with acute lymphoblastic leukemia (ALL) to determine the clinical impact of minimal/measurable residual disease (MRD) and recently identified tumor genetic subtypes. Methods: Genetic subtypes were determined by sequential approaches including DNA ind...

Identification of specific leukemia subtype is one of the keys to successful risk-directed therapy in childhood acute lymphoblastic leukemia (ALL). Although RNA sequencing (RNA-seq) is the best approach to identify virtually all specific leukemia subtypes, the routine use of this method is too costly for patients in resource-limited countries. This...

Introduction: The large interpatient variability in the pharmacokinetic (PK) parameters of recombinant Factor VIII (rFVIII) observed in haemophilia A hinders efficient and cost-beneficial prophylactic regimen initiation. Identification of factors influencing the PK of rFVIII may shed more light on personalised treatment. Aim: This study aimed to...

Improvement in outcomes of children with acute myeloid leukemia (AML) is attributed to several refinements in clinical management. We evaluated treatment outcomes of Taiwanese pediatric AML patients in the past 20 years. Overall, 860 de novo AML patients aged 0–18 years and registered in the Childhood Cancer Foundation of R.O.C during January 1996–...

Philadelphia chromosome-like (Ph-like) acute lymphoblastic leukaemia (ALL), a high-risk subtype characterised by genomic alterations that activate cytokine receptor and kinase signalling, is associated with inferior outcomes in most childhood ALL clinical trials. Half of the patients with Ph-like ALL have kinase rearrangements or fusions. We examin...

Sarcomas of bone, soft tissue, or neural origin may occasionally invade the central nervous system (CNS), causing diagnostic and therapeutic challenges. We aim to investigate the clinical features of sarcomas involving the CNS at initial presentation. During 2015/01–2019/12, nine consecutive patients (4 Males and 5 Females) younger than 30 years of...

Although the cure rate for childhood acute lymphoblastic leukemia (ALL) has exceeded 80% with contemporary therapy, relapsed ALL remains a leading cause of cancer-related death in children. Relapse-specific mutations can be identified by comprehensive genome sequencing and might have clinical significance. Applying whole-exome sequencing to eight t...

Aneuploidy occurs within a significant proportion of childhood B-cell acute lymphoblastic leukemia (B-ALL).

Backgrounds and Purposes Minimal residual disease (MRD) monitoring has been proved to be the most important prognostic predictor in childhood acute lymphoblastic leukemia (ALL). The nationwide TPOG-ALL-2013 protocol (TPOG-2013), adapted from the St. Jude Total Therapy XV Study and Total Therapy XVI Study, was launched since January 2013. This is th...

Background To provide information for umbilical cord blood (UCB) banks to adopt optimal collection strategies and to make UCB banks operate efficiently, we investigated the reasons for exclusion of UCB units in a 3-year recruitment period. Study Design and Methods We analyzed records of the reasons for exclusion of the potential UCB donation from 2...

Allogeneic hematopoietic stem cell transplantation is now an important treatment for numerous diseases. Donation of hematopoietic stem cells, either through bone marrow (BM) harvesting or peripheral blood stem cell (PBSC) collection, is a well-established and generally accepted procedure. The BM is aspirated from the posterior iliac crest under spi...

Background: The outcome of peripheral blood stem cell (PBSC) harvest depends on mobilization and leukapheresis. Some poor harvests might not be directly related to poor mobilizations. Study design and methods: We retrospectively analyzed the results of 793 consecutive healthy donors who underwent PBSC donation to evaluate the impact of low mean...

Maternal-fetal ABO incompatibility is one of the causes of neonatal hyperbilirubinemia. We postulate that hemoglobin (Hb), hematocrit (Hct), and red blood cell (RBC) values for cord blood units (CBUs) are lower and erythroblast values higher for maternal-fetal ABO incompatible dyads than for compatible dyads. We investigated the relationship betwee...

Pyomyositis is a pyogenic muscular tissue infection mainly occurring in immunocompromised patients. Chronic myeloid leukemia (CML) accounts for only 2-3% of cases of childhood leukemia. Herein, we report on a 17-year-old male with bilateral hip pain caused by adductor pyomyositis before beginning the treatment course of CML. CML was diagnosed by bo...

Cord blood banking has become more popular in recent years. Checking cord blood complete blood count (CBC) and white blood cell (WBC) differential counts (DCs) is essential before cryopreserving the cord blood units. Therefore, establishing the normal reference values of cord blood CBC and WBC DC is important in clinical practice and research. Obje...

Granulocyte colony-stimulating factor (G-CSF) is now widely used for stem cell mobilization. We evaluated the role of post-G-CSF white blood cell (WBC) counts and donor factors in predicting adverse events and yields associated with mobilization. WBC counts were determined at baseline, after the third and the fifth dose of G-CSF in 476 healthy dono...

Objectives: Unrelated hematopoietic stem cell donors may donate twice. We studied donors' preference for peripheral blood stem cell (PBSC) collection or bone marrow (BM) harvest and compared the yields of and side effects associated with two BM harvests. Materials and Methods: The psychosocial and physical experience of 13 donors who underwent two...

To improve bone marrow (BM) harvest of the volunteer donors in our institute, we changed from the single-hole needle to the multi-side-hole needle after March 2002, and examined the midway total nucleated cell (TNC) counts during collection after September 2004. The aims of this retrospective study were to evaluate BM harvest yields obtained throug...

The hematopoietic progenitor cell (HPC) count measured by the Sysmex hematology analyzer can determine the timing for leukapheresis in autologous peripheral blood stem cell (PBSC) harvest. We evaluated whether a HPC count could predict CD34+ cell yield in healthy, unrelated donors after granulocyte-colony-stimulating factor mobilization. A total of...

The demographic and clinical data of 55 cases were analyzed. Thirty-two cases presented from the beginning of 1997 to the end of 1998, when the most severe El Niño in the century occurre...

The association of chronic diarrhea with neural-crest tumors is uncommon. In the past 12 years, we encountered three cases of neural-crest tumors presenting initially as chronic diarrhea. The incidence of chronic diarrhea in patients with neural-crest tumors at our hospital during this period was 3.8%. These patients (two girls and one boy aged bet...

The authors sought to determine whether recombinant human thrombopoietin (TPO) acts synergistically with other cytokine(s) on burst-forming unit-erythroid (BFU-E)-derived and colony-forming unit-granulocyte/macrophage (CFU-GM)-derived colony formations from cord blood of premature neonates. Cord blood nonadherent mononuclear cells (MNC) from normal...

The classification of B-lineage acute lymphoblastic leukemia (ALL) by specific chromosomal translocations may have prognostic implications. Reverse transcriptase-polymerase chain reaction (RT-PCR) assay is a useful tool for the detection of fusion transcript resulting from specific chromosomal translocation of the leukemic cells. In general, fusion...

Recently, an internal tandem duplication of the FLT3 gene (FLT3/ITD) was found in approximately 20% of adult acute myeloid leukemia (AML) cases and associated with a poor outcome. However, there are few studies on FLT3/ITD in childhood AML, and the clinical significance of FLT3/ITD is thus unclear. FLT3/ITD was analyzed in 80 children with de novo...

About 30% of neuroblastomas exhibit N-myc amplification. Neuroblastomas with Nmyc amplification tend to have a stroma-poor undifferentiated histopathologic phenotype and a high mitosis-karyorrhexis index (MKI). Karyorrhectic or pyknotic cells in neuroblastomas are closely related to apoptosis. Using fluorescence in situ hybridization (FISH) techniq...
