BACKGROUND The Fuhrman system is the most widely used nuclear grading system for renal cell carcinoma (RCC). Although Fuhrman nuclear grade is widely accepted as a significant prognostic factor, its reproducibility, as reported in the limited number of series available in the literature, appears to be low. METHODS Between 1980 and 1990, 255 cases of RCC(More)
Human clear cell renal cell carcinoma (CRCC) remains resistant to therapies. Recent advances in Hypoxia Inducible Factors (HIF) molecular network led to targeted therapies, but unfortunately with only limited clinical significance. Elucidating the molecular processes involved in kidney tumorigenesis and resistance is central to the development of improved(More)
The purpose of our study was to evaluate the role of MRI in demonstrating the precise nature of papillary renal tumors (P RCC) and its potential application to select patients for partial surgery. Ninety-seven tumors less than or equal to 3 cm in size [55 papillary renal cell carcinoma - 42 clear cell renal carcinoma (CC RCC)] were preoperatively evaluated(More)
Metastatic renal cell carcinoma is resistant to current therapies. The phosphoinositide 3-kinase (PI3K)/Akt signaling cascade induces cell growth, cell transformation, and neovascularization. We evaluated whether targeting this pathway could be of therapeutic value against human renal cell carcinoma. The activation of the PI3K/Akt pathway and its role in(More)
Alterations at microsatellite DNA markers in cells exfoliated in urine have been correlated to the presence of bladder cancer. To check the feasibility of such noninvasive analysis to routinely diagnose bladder cancers, we have developed a highly sensitive method using fluorescent PCR to search for DNA microsatellite alterations in urine sediment compared(More)
OBJECTIVE Incidence of multifocality in Renal Cell Carcinoma (RCC) is estimated at between 5 and 25%. Multifocality has been largely studied because of the growing interest in conservative surgery which is a risk of local recurrence. The aim of this study is to evaluate the relationship between multifocality and other prognostic parameters and whether it is(More)
Clear cell renal carcinoma (CCRC) is responsible for 2% of cancer-related deaths worldwide and is resistant to virtually all therapies, indicating the importance of a search for new therapeutic targets. Parathyroid hormone-related protein (PTHrP) is a polyprotein derived from normal and malignant cells that regulates cell growth. In the current study, we(More)
Fluorescence-based enhanced reality (FLER) is a technique to evaluate intestinal perfusion based on the elaboration of the Indocyanine Green fluorescence signal. The aim of the study was to assess FLER’s performances in evaluating perfusion in an animal model of long-lasting intestinal ischemia. An ischemic segment was created in 18 small bowel loops in 6(More)
Metastatic renal cell carcinoma (RCC) remains refractory to therapies. The nuclear factor-kappaB (NF-kappaB) transcription factor is involved in cell growth, cell motility, and vascularization. We evaluated whether targeting NF-kappaB could be of therapeutic and prognostic values in human RCC. The activation of the NF-kappaB pathway in human RCC cells and(More)
Human conventional renal cell carcinoma (CRCC) remains resistant to therapy. The RNA-binding protein HuR regulates the stability and/or translation of multiple messenger RNAs involved in malignant transformation. In this study, we aimed to evaluate the potential role of HuR in this pathology. Using seven human CRCC cell lines expressing or not the von(More)
