Cancer Genetics Inc to Present New Data on Identification of Genomic Changes That Predict Both Metastasis and Site of Metastasis in Kidney Cancer at the 2015 ASCO Genitourinary Cancers Symposium

> CGI's genomic signature, developed in a research collaboration with Memorial Sloan-Kettering, predicts metastasis for clear-cell renal cell carcinoma (ccRCC)

> Clear cell renal cell carcinoma is the most common form of kidney cancer with nearly 43,000 new cases in the US each year and 200,000 globally per year

RUTHERFORD, N.J., Feb. 24, 2015 (GLOBE NEWSWIRE) -- Cancer Genetics Inc (Nasdaq:CGIX) ("CGI" or "the company"), an emerging leader in DNA-based cancer diagnostics, announced today that it has identified genomic signatures that can differentiate those patients with clear cell renal carcinoma (ccRCC) whose disease is likely to relapse or metastasize. The signatures were identified in a collaborative study with Memorial Sloan-Kettering Cancer Center (MSKCC) which analyzed and genomically assessed specimens from 144 patients with both primary and metastatic lesions. Genomic signatures identified in this study have the potential to allow for better risk stratification and guided treatment selection for patients with metastatic ccRCC. CGI plans on integrating signatures identified in this study into an NGS-based panel for kidney cancer, which the company expects to be CLIA-certified and available for use for both clinical trials and clinical diagnosis and management of patients.

Clear cell renal cell carcinoma (ccRCC) is the most common subtype of kidney cancer, with approximately 43,000 new cases diagnosed in the US each year. Approximately 20-30% of ccRCC patients relapse within three years after nephrectomy. Identifying patients whose disease is likely to relapse or metastasize is essential for planning appropriate treatment strategies and improving outcome. Copy number variations in samples from patients whose disease had metastasized to the lung or bone (the two most common sites for metastasis of ccRCC) were also identified and validated in an independent dataset. For patients with early-stage disease, accurate prediction of metastatic activity will enable the delivery of personalized precision medicine with the goal of improving outcomes.

Results of the study will be presented at the Genitourinary Cancers Symposium of the American Society of Clinical Oncology (GU-ASCO). The poster presentation, titled "Association of genome-wide copy number alterations with metastasis of clear cell renal cell carcinoma" will be delivered by Banumathy Gowrishankar, Ph.D., principal clinical scientist at Cancer Genetics, on February 28 at 7:00am Eastern Time at the Rosen Shingle Creek in Orlando, Florida.

About the Genitourinary Cancers Symposium

The Genitourinary Cancers Symposium is a specialized oncology event designed for the exchange of the latest strategies in prevention, screening, diagnosis, and treatment of prostate, renal, testicular, and urothelial cancers. The symposium is cosponsored by the American Society for Clinical Oncology (ASCO), American Society for Therapeutic and Radiation Oncology (ASTRO) and the Society for Urologic Oncology (SUO).
