INTRODUCTION Minimally invasive surgery (CMI) for the treatment of malignant tumors in children begins to have a role for selected cases and reaches similar results than open surgery. We show our first two cases of Wilms tumor treated by laparoscopy describing patients and technique. MATERIAL AND METHODS Three-year-old girl with macroscopic hematuria is diagnosed of 8 cm mass in the left kidn...

The overall frequency of WT1 gene alterations in Wilms tumor is still unclear in Taiwan. Here we conducted molecular genetic analysis of the WT1 gene in Taiwanese patients with Wilms tumor. Polymerase chain reaction and direct sequencing were performed on DNA samples from blood and paraffin-embedded tumor specimens. A constitutional mutation in the WT1 gene was found in one DNA sample from peri...

BACKGROUND Loss of imprinting (LOI) of the H19/IGF2 domain is a common feature of Wilms tumour. The GTL2/DLK1 domain is also imprinted and is structurally similar to H19/IGF2. The question arises as to whether DLK1 also undergoes LOI in Wilms tumour, or whether the LOI mechanism is restricted to the H19/IGF2 domain. AIM To investigate the imprinting status of DLK1 in Wilms tumours with IGF2 L...

UNLABELLED Wilms tumor is rare in adults. Though the approach to diagnosis and treatment of adult Wilms tumor (AWT) is closely modeled on recommendations for childhood Wilms tumor, views differ on how aggressive the treatment should be. We report a case of a 37-year-old with Stage III favorable histology AWT. A radical nephrectomy was performed and the patient was due for chemotherapy. Recent a...

An analysis of over 1800 patients with Wilms' tumor revealed significantly higher birth weights than newborns in the general United States population. The highest birth weights were found not only in patients diagnosed with the Beckwith-Wiedemann syndrome (mean, 3.78 kg), as had been expected, but also in those with hemihypertrophy (3.80 kg) or perilobar nephrogenic rests (3.56 kg) in addition ...

Wilms' tumor is the most common childhood renal malignancy. A genome-wide association study identified LIM domain only 1 (LMO1) as having oncogenic potential. We examined the associations between LMO1 gene polymorphisms and susceptibility to Wilms' tumor. In this hospital-based, case-control study, we recruited 145 children with Wilms' tumor and 531 cancer-free children. Four polymorphisms (rs1...

PURPOSE To determine the role of methylation of HIC1, a candidate tumor suppressor gene on 17p13.3, in various types of pediatric tumors. EXPERIMENTAL DESIGN We examined the methylation status of the HIC1 promoter by methylation specific PCR in 157 pediatric tumors and 27 nonmalignant tissues. We correlated methylation with mRNA expression by reverse transcription-PCR in eight tumor-derived c...

Wilms' tumor is a childhood nephroblastoma that is postulated to arise through the inactivation of a tumor suppressor gene by a two-hit mechanism. A candidate II p 13 Wilms' tumor gene, WT I, has been cloned and shown to encode a z:inc finger protein. Patients with the WAGR syndrome (Wilms' tumor, aniridia, genitourinary abnormalities, and mental retardation) have a high risk of developing Wilm...

OBJECTIVE To investigate the attenuating effect of curcumin, an anti-inflammatory compound derived from dietary spice turmeric (Curcuma longa) on the pro-inflammatory insulin-resistant state in 3T3-L1 adipocytes. METHODS Glucose uptake rate was determined with the [3H] 2-deoxyglucose uptake method. Expressions of tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) were measured b...

Wilms’ tumor is the most frequently occurring renal tumor in children and is one of the most treatment-responsive tumors. A tumor-suppressor gene and other genetic abnormalities have been implicated in its etiology. In addition, patients with several congenital anomalies, such as Beckwith-Wiedemann syndrome, WAGR syndrome, and DenysDrash syndrome, have an increased risk of Wilms’ tumor. Previou...
