Wilms' tumor has served as an example of Knudson's two-hit hypothesis of recessive tumor genes, but the genetics has proven to be surprisingly complex. WT1, a tumor suppressor gene on 11p13, is mutated in only a small fraction of Wilms' tumors, and a second chromosomal region, 11p15, harbors a second Wilms' tumor gene also involved in other cancers. In addition, loss of genomic imprinting, or p...

OBJECTIVE The current study was undertaken to explore the clinical and prognostic value of phosphatase of regenerating liver-3 (PRL-3) expression in Wilms' tumor. METHODS Seventy-six patients with Wilms' tumor in Qilu Hospital from January 2003 to July 2009 were enrolled in the study. Protein expression level of PRL-3 was examined by immunohistochemical staining, and the correlation between P...

The incidence of horseshoe kidney is about 1 in 400 cases. The presence of Wilms' tumor with a horseshoe kidney is unusual, and the occurrence of Wilms' tumor in a horseshoe kidney is estimated at 0.4 to 0.9% of all Wilms' tumors. We report the case of a 5-year-old boy who presented with a stage IV Wilms' tumor in a horseshoe kidney. The patient was treated with preoperative chemotherapy follow...

BACKGROUND The Wilms tumor 1 (WT1) gene is originally defined as a tumor suppressor gene and a transcription factor that overexpressed in leukemic cells. It is highly expressed in more than 80% of acute myeloid leukemia (AML) patients, both in bone marrow (BM) and in peripheral blood (PB), and it is used as a powerful and independent marker of minimal residual disease (MRD); we have determined ...

Aim. Evaluate tumor proliferation marker (Ki67) and p53 tumor suppressor marker in Wilms tumor and correlate with histology, anaplasia, and staging. Design. Prospective, hospital based study conducted at a tertiary pediatric referral centre in south India. Setting. Wilms tumor is the most common childhood renal malignancy worldwide. Anaplasia on histology is associated with treatment resistance...

The Pax gene family encodes transcription factors with similar structures but distinctive roles in development and with limited expression in adult tissues. Reexpression of PAX proteins is frequently observed in human cancers, reflecting recapitulation of embryologic or developmental function. Defining expression of PAX family members is important in the immunohistochemical differential diagnos...

Background and Objective: Wilms’ tumor has been recognized as the most common primary malignancy of kidney at childhood, comprises 5-6% of tumors in this period, and manifests itself with various clinical symptoms. Since there have been no sufficient studies in this field in Iran, therefore, this study w...

wilms' tumor (wt) is the most common primary renal tumor in children. common sites of metastases are lungs, liver and regional lymph nodes. testicular and paratesticular metastasis due to wt have been reported but it is extremely rare. we report a 33-month -old male with bilateral wt and metastasis to right spermatic cord.
