To determine whether keratinocyte growth factor (KGF), an epithelial and urothelial growth factor, ameliorates cyclophosphamide (CP)-induced cystitis in rats, KGF (5 mg/kg) was injected in rats as a single i.v. injection 24 h prior to i.p. injection of CP (200 mg/kg). Bladders were evaluated histologically 48 h after CP injection, and KGF pretreatment was found to almost completely prevent CP-induced ulcerative hemorrhagic cystitis. Urinary KGF levels were measured by ELISA, and KGF was found to

AIMS: We aimed to investigate the impact of various genetic polymorphisms affecting thiopurine metabolism pathways and toxicity in paediatric acute lymphoblastic leukaemia patients for the first time in Korea. METHODS: From May 2006 to September 2016, 139 paediatric acute lymphoblastic leukaemia patients treated with combination chemotherapy including 6-mercaptopurine were included in the study. One hundred and twenty-three variants in 43 genes, including TMPT and NUDT15, were screened using tar

NUDT15 variants cause hematopoietic toxicity with low 6-TGN levels. NUDT15 genotyping should be conducted before administering thiopurine, and dose adjustments require caution regardless of 6-TGN levels.

The required dose of craniospinal RT might be reduced in older patients if the intensity of chemotherapy is increased. However, early administration of RT should be considered to prevent early progression in young patients.

Neuroblastoma (NB) is the most common extra-cranial solid tumor of childhood and is characterized by a wide range of clinical behaviors. Amplification of MYCN is a well-known poor prognostic factor in NB patients. As the MYCN amplification status is usually tested using tumor specimens, lengthy and invasive procedures are unavoidable. To evaluate the possibility of detecting MYCN amplification without invasive procedure, we performed conventional polymerase chain reaction (PCR) analysis to ident

PURPOSE: The purpose of this study is to investigate the clinical significance of tyrosine hydroxylase (TH) expression in peripheral blood (PB) at diagnosis in patients with neuroblastoma. MATERIALS AND METHODS: expression in PB at diagnosis was evaluated. RESULTS: expression in PB at diagnosis was an independent poor prognostic factor for PFS. CONCLUSION: expression in PB at diagnosis.

BackgroundKasabach-Merritt syndrome (KMS) is a rare but life-threatening illness.The purpose of this study is to report our single-center experience with KMS. MethodsWe reviewed the medical records of 13 patients who were diagnosed with KMS between 1997 and 2012 at Samsung Medical Center.Treatment response was defined as follows: 1) hematologic complete response (HCR) -platelet count ＞130×10 9 /L without transfusion; 2) clinical complete response (CCR) -complete tumor disappearance or small resi

This study suggests that CB recipients had both longer and higher cumulative incidences of CMV infection. Therefore, a more aggressive and effective strategy of CMV management should be considered in CB recipients.

Survival after UCB transplantation was similar to survival after MRD and URD transplantation. For patients lacking an HLA matched donor, the use of UCB is a suitable alternative.

Abstract Objective This study aims to explore prognostic factors for high‐risk neuroblastoma patients with response failure to tandem high‐dose chemotherapy and autologous stem cell transplantation (HDCT/auto‐SCT). Methods Survival outcomes were compared according to characteristics at initial diagnosis, at relapse/progression, and after relapse/progression in patients who experienced relapse/progression after tandem HDCT/auto‐SCT from 2006 to 2018. Results Forty‐nine patients experienced relaps
