The current classification of renal-cell adenomas (RCAs) and carcinomas (RCCs) is based on eight basic cell and tumor types (entities) with characteristic morphologic features: (1) RCCs of clear-cell type, (2) RCAs/RCCs of chromophilic-cell type, (3) RCAs/RCCs of chromophobic-cell type, (4) RCCs of duct Bellini type, (5) RCCs of transitional-cell type, (6)(More)
PURPOSE Leiomyosarcomas (LMS) of deep and superficial tissues were examined to identify prognostic markers explaining their different biological behaviour and to define differences between cutaneous and subcutaneous LMS. LMS and leiomyomas (LM) of the skin were compared to and consistent differences that could aid in the (sometimes difficult) diagnosis. (More)
A combination of Southern blot analysis on a panel of tumor-derived somatic cell hybrids and fluorescence in situ hybridization (FISH) techniques was used to map a series of DNA markers relative to the 1q21 breakpoint of the renal cell carcinoma (RCC)-associated (X;1)(p11;q21) translocation. This breakpoint maps between several members of the S100 family(More)
Soft tissue sarcomas (STSs) are rare tumors, notorious for early hematogenous metastasizing. Metastatic disease is seldom amenable to curative treatment; therefore new treatment modalities are required. Treatment-related and tumor-related prognostic factors can be assessed to estimate the risk for subsequent metastases, as will be discussed. By this means,(More)
Chronic periaortitis is thought to result from an autoallergic reaction to oxidized low-density lipoprotein (OxLDL). No data exist on lipid profile and atherosclerotic biomarkers. We investigated circulating levels of OxLDL and of anti-OxLDL (aOxLDL) antibodies in patients with chronic periaortitis using the cross-sectional case–control study on 20 patients(More)
The transcriptional activity of the tandem promoters of the Escherichia coli uvrB gene was measured in vivo. Both promoters are shown to be inducible by UV irradiation. P1, the most proximal promoter, is responsible for the main part of transcription both in uninduced and induced cells. Plasmids have been constructed carrying small deletions in the lexA(More)
Recent cytogenetic analysis of a series of human renal oncocytomas revealed the presence of a recurring chromosomal translocation (5;ll)(q35;ql3) as sole anomaly in a subset of the tumors. The molecular characterization of this translocation was initiated using two primary t(5;ll)-positive renal oncocytomas and a panel of soma tic cell hybrids derived from(More)
Purpose: Postradiation sarcoma, a sarcoma developing in a previously irradiated field, is a rare tumor. Surgery appears to be the only curative treatment option. In general the prognosis is poor, and new treatments options are needed. One study reported the expression of KIT receptor tyrosine kinase in two postradiation angiosarcomas. Success of inhibition(More)
