Discovery and Validation of a 15-Gene Prognostic Signature for Clear Cell Renal Cell Carcinoma

Project description:We report a kidney cancer tissue-based prognostic biomarker encompassing 15 genes (15G score) to classify patients into low versus high risk for recurrence after curative nephrectomy. The 15G score was independently associated with disease free survival adjusting for clinicopathologic variables as well as existing clinical risk calculators or nomograms. By improving risk stratification of patients with ccRCC, the 15G score has the capacity to facilitate selection of biopsy confirmed small renal cancers (T1a) for treatment versus surveillance; inform intensity and duration of surveillance after curative nephrectomy; and to potentially facilitate patient selection for adjuvant systemic therapy. We retrospectively identified 110 patients who underwent radical nephrectomy for ccRCC (discovery cohort). Patients who recurred were matched based on grade/stage to patients without recurrence. Capture whole transcriptome sequencing was performed on RNA isolated from archival tissue using the Illumina platform. We developed a gene-expression signature to predict recurrence/disease-free survival (DFS) using a 15-fold lasso and elastic-net regularized linear Cox model. We derived the 31-gene cell cycle progression (mxCCP) score using RNAseq data for each patient. Kaplan-Meier (KM) curves and multivariable Cox proportional hazard testing were used to validate the independent prognostic impact of the gene-expression signature on DFS, disease specific survival (DSS) and overall survival (OS) in two validation datasets (combined n=761).

Array based miRNA Profiling of Clear Cell Renal Cell Cance

Project description:MicroRNAs (miRNAs) are short single stranded RNAs that are associated with gene regulation at the transcriptional and translational level. Changes in their expression were found in a variety of human cancers. Because of the lack of corresponding data in clear renal cell carcinoma (ccRCC) we have performed genome-wide expression profiling of miRNAs using microarray analysis and quantification of specific miRNAs by TaqMan real-time RT-PCR. Matched malignant and non-malignant tissue samples from two independent 12 ccRCC sets were profiled. The microassay-based experiments identified 14 overexpressed and 20 downregultaed miRNAs in malignant samples. Expression in ccRCC tissue samples compared to matched non-malignant samples measured by RT-PCR was increased by 2.7 to 28fold for the hsa-mir-16, -452, -224, -155, and -210, but decreased by 6.2 to 96fold for hsa-mir-200b, -363, , -429, -200c, -514, and -141. No significant associations between these differentially expressed miRNAs and the clinico-pathological factors tumor stage, grade, and survival rate were found. Nevertheless, malignant and non-malignant tissue could clearly be differentiated by their miRNA profile . A combination of miR-141 and miR-155 resulted in a 96% overall correct classification of samples. The presented differential miRNA pattern provides a solid basis for further validation including functional studies. The study was performed with two independent sample sets. For each set 12 kidney tissue sample pairs were derived from adult patients undergoing radical nephrectomy at the University Hospital CharitÃ©. All tumor types were clear renal cell carcinoma. Tumor classification and stage were established according to the 2002 TNM System and the 2004 WHO Classification. Matched malignant (#NC (e.g. 2NC)) and non-malignant (#NN (e.g. 1NN)) tissue samples from two independent 12 ccRCC sets were profiled.
