We have analyzed several cases of Beckwith-Wiedemann syndrome (BWS) with Wilms' tumor in a familial setting, which give insight into the complex controls of imprinting and gene expression in the chromosome 11p15 region. We describe a 2.2-kbp microdeletion in the H19/insulin-like growth factor 2 (IGF2)-imprinting center eliminating three target sites of the chromatin insulator protein CTCF that ...
BACKGROUND Although the NWTSG and SIOP studies have included the largest number of patients, several individual institutions have made likewise important contributions to the optimization of Wilms' tumor therapy. The purpose of this study is to present our personal experience obtained in the last 42 years by treating Wilms' tumor in childhood. PATIENTS AND METHODS Throughout the period 1965-2...
PURPOSE A number of studies have indicated that the tumor proliferation marker MIB-1 and cell cycle inhibitor p27(Kip1) expression are of prognostic importance in a variety of cancers. The present study was performed to evaluate the prognostic value of these molecules in Wilms' tumors. EXPERIMENTAL DESIGN MIB-1 and p27(Kip1) expressions were investigated by the means of immunohistochemical an...
The Wilms' tumor suppressor gene, wt1, encodes a zinc-finger transcription factor, WT1, that represses transcription of a number of growth-promoting genes and inhibits cell growth. The transcripts of wt1 undergo two alternative splicing events, giving rise to four isoforms of mRNA in constant ratios. The first alternative splice introduces an extra exon 5, which encodes 17 amino acid residues i...
A 64-year-old man underwent left radical nephrectomy for stage III anaplastic Wilms’ tumor. He received adjuvant chemotherapy consisting of cisplatin and etoposide. Complete clinical response was achieved and maintained for 12 months. A systemic relapse after 1 year also responded to three more cycles of cisplatin and etoposide. Although cisplatinand etoposide-based chemotherapy was not used as...
