An eleven-month old male F344/DuCrj (F344) rat was found dead and had right kidney mass at necropsy. Histopathologically, the mass was composed of nests of neoplastic stellate cells. At the center of the nests, neoplastic epithelial cells formed a tubular structure. In the fibrous connective tissue surrounding the nests, neoplastic cells with striations demonstrable by phosphotungstic acid hematoxylin were observed. Immunohistochemically, neoplastic stellate cells were partially positive for Wilms Tumor 1 and vimentin, and neoplastic cells with striations were partially positive for desmin...

OBJECTIVE: The Children's Oncology Group study AREN0534 aimed to improve event-free survival (EFS) and overall survival (OS) while preserving renal tissue by intensifying preoperative chemotherapy, completing definitive surgery by 12 weeks from diagnosis, and modifying postoperative chemotherapy based on histologic response. BACKGROUND: No prospective therapeutic clinic trials in children with bilateral Wilms tumors (BWT) exist. Historical outcomes for this group were poor and often involved prolonged chemotherapy; on NWTS-5, 4-year EFS for all children with BWT was 56%...

BACKGROUND: Minimally invasive surgery (MIS) has been widely adopted for common operations in pediatric surgery; however, its role in childhood tumors is limited by concerns about oncologic outcomes. We compared open and MIS approaches for pediatric neuroblastoma and Wilms tumor (WT) using a national database. METHODS: The National Cancer Data Base from 2010 to 2012 was queried for cases of neuroblastoma and WT in children ≤21 years old. Children were classified as receiving open or MIS surgery for definitive resection, with clinical outcomes compared using a propensity matching methodology (two open:one MIS)...

BACKGROUND: DNA methyltransferase 3A (DNMT3A) mutations have been found in approximately 20% of adult acute myeloid leukemia (AML) patients and in 0% to 1.4% of children with AML, and the hotspots of mutations are mainly located in the catalytic methyltransferase domain, hereinto, mutation R882 accounts for 60%. Although the negative effect of DNMT3A on treatment outcome is well known, the prognostic significance of other DNMT3A mutations in AML is still unclear. Here, we tried to determine the incidence and prognostic significance of DNMT3A mutations in a large cohort in Chinese childhood AML...

INTRODUCTION: SIL-TAL1 rearrangement is common in T-cell acute lymphoblastic leukemia (T-ALL). However, whether this fusion gene might be used as a reliable marker of minimal residual disease (MRD) following allogeneic stem cell transplantation (allo-HSCT) remains unknown METHODS: The clinical data of consecutive 29 patients with T-ALL who received allo-HSCT were collected. Their MRD were evaluated by SIL-TAL1, Wilms' tumor 1 (WT1) expression, and the leukemia-associated immunophenotype (LAIP) ...

BACKGROUND: Neonatal tumors are different from tumors of the older children and knowledge gained from treating older children can not be extrapolated to neonates. Neonates have immature physiology and their haematopoietic and immune systems are not fully developed and the response to therapy is unpredictable. Hence it is imperative to study these tumors as separate entity. The aim of this study is to analyse this rare set of tumors in terms of their incidence, clinical features and management...

Gastroblastoma is a rare distinctive biphasic tumor of the stomach. The molecular biology of gastroblastoma has not been studied, and no affirmative diagnostic markers have been developed. We retrieved two gastroblastomas from the consultation practices of the authors and performed transcriptome sequencing on formalin-fixed paraffin-embedded tissue. Recurrent predicted fusion genes were validated at genomic and RNA levels. The presence of the fusion gene was confirmed on two additional paraffin-embedded cases of gastroblastoma...

Cancer stem cells (CSC) form a specific population within the tumor that has been shown to have self-renewal and differentiation properties, increased ability to migrate and form metastases, and increased resistance to chemotherapy. Consequently, even a small number of cells remaining after therapy can repopulate the tumor and cause recurrence of the disease. CSCs in Wilms tumor, a pediatric renal cancer, were previously shown to be characterized by neural cell adhesion molecule (NCAM) expression. Therefore, NCAM provides a specific biomarker through which the CSC population in this tumor can be targeted...

BACKGROUND: Hemolytic uremic syndrome (HUS) can occur as a primary process due to mutations in complement genes or secondary to another underlying disease. HUS sometimes occurs in the setting of glomerular diseases, and it has been described in association with Denys-Drash syndrome (DDS), which is characterized by the triad of abnormal genitourinary development; a pathognomonic glomerulopathy, diffuse mesangial sclerosis; and the development of Wilms tumor. CASE PRESENTATION: We report the case of a 46, XX female infant who presented with HUS and biopsy-proven thrombotic microangiopathy...

Wilms' tumor is associated with a high treatment success rate, but there is still a risk of recurrence. Cisplatin, which is one of the chemotherapeutic agents used for its treatment, is associated with a very high rate of resistance. Par-4 (prostate apoptosis response 4) is a tumor suppressor, which is capable of sensitizing tumor cells to chemotherapy. Therefore, the aim of this study was to determine whether combined treatment with Par-4 and cisplatin is effective for inhibiting growth of Wilms' tumor. Wilms' tumor and control cell samples were collected and analyzed by immunofluorescence assay and immunohistochemistry...

BACKGROUND/AIMS: Diabetic nephropathy (DN) is a microangiopathic disease characterized by excessive urinary albumin excretion, which occurs in 30% of patients with diabetes mellitus. It is the second leading cause of end-stage renal diseases in China. Nuclear factor-kappa B (NF-κB) is reported to be closely correlated with the inflammation underlying diabetes-associated renal damage. Crocin, a plant-derived compound, has antioxidant properties that may inhibit NF-κB. METHODS: In the present study, we used a conditionally immortalized mouse podocyte cell line to explore whether crocin could effectively block albuminuria...

BACKGROUND: Though the association between parental age at child's birth and the risk of childhood cancer has been previously investigated, the evidence to date is inconclusive and scarce for rarer cancer types. METHODS: Cancer cases (N=5,856) were selected from all children born from 1968 to 2014 and diagnosed from 1968 to 2015 in Denmark at less than 16 years of age listed in the nationwide Danish Cancer Registry. Cases were individually matched to controls (1:100) on sex and year of birth with a total of 585,594 controls randomly sampled from all live births in Denmark from the Danish Central Population Registry...

BACKGROUND: Mechanical stress is a key pathogenic driver of apoptosis in the tubular epithelium in obstructive nephropathy. Heat shock protein 70 (Hsp70) and Wilms' tumor (WT-1) have been proposed to represent linked downstream effectors of the cytoprotective properties of NO. In the present study, we sought to evaluate whether the cytoprotective effects of L-arginine in neonatal obstructive nephropathy may be associated with NO-dependent increases in WT-1 and Hsp70 expression. METHODS: Neonatal Wistar-Kyoto rats were submitted to complete unilateral ureteral obstruction (UUO) and treated thereafter with vehicle, L-NAME or L-arginine by daily gavage for 14 days to block or augment NO levels, respectively...

Wilms tumor (WT) is the most common renal malignancy of childhood and the fourth most common pediatric solid malignancyin the United States. While the mechanisms underlying the WT biology are complex, these tumors most often demonstrate activation of the canonical Wnt/ß-catenin pathway. We and others have shown that constitutive activation of ß-catenin restricted to the renal epithelium is sufficient to induce primitive renal epithelial tumors which resemble human WT. Here we demonstrate that pharmacologic inhibition of ß-catenin gene transcription with pyrvinium inhibits tumor growth and metastatic progression in a murine model of WT...

The Beckwith-Wiedemann syndrome is a cancer predisposition syndrome characterized by a predilection to embryonal tumor growth, especially Wilms tumor, adrenocortical carcinomas, and hepatoblastomas. Genetic analysis of patients has revealed a link to the imprinted domain of the 11p15.5 chromosome and methylation status of the H19 locus and Igf-2. These genes have also been studied in other cancers, including ovarian teratomas. Our case is a patient with a simultaneous presentation of a Wilms tumor and immature ovarian teratoma and subsequently diagnosed with Beckwith-Wiedemann syndrome, which has not been previously described...

Diabetes mellitus (DM) affects male reproductive system and causes infertility. The male reproductive health is largely dependent upon uptake and proper utilization of glucose by testicular cells. Results show involvement of orexin A (OXA) and its receptor (OX1R) in regulation of steroidogenesis and glucose homeostasis in adult mice testis. However, the role of OX1R in regulation of testicular functions during hyperglycemia has not been investigated so far. The present study, therefore, examined the role of OX1R in regulation of steroidogenesis and glucose homeostasis in testis of adult mice during alloxan-induced type 1 DM...

The timing and role of chemotherapy in the management of Wilms' tumor has long been the matter of debate, with different groups showing equally comparable and encouraging results. Over the last decade, however, both the ideol-ogies seem to be converging and the attempt has been to identify groups benefitting with pre-operative chemotherapy, as well as those, where upfront resection should be attempted. In this article authors intend to discuss pros and cons of both the strategies and their applicability in a resource poor setting in developing countries like India...
