Response Genetics to Announce Bladder, Colon and Colorectal Cancer Results at the 2009 American Society of Clinical Oncology Annual Meeting.
LOS ANGELES -- Response Genetics Inc. (Nasdaq:RGDX), a company focused on the development and sale of molecular diagnostic tests for cancer, will announce the results of studies in bladder cancer, colon cancer
and colorectal cancer that identify genes associated with positive chemotherapy outcome and tumor recurrence. Results will be presented during the 2009 American Society of Clinical Oncology American Society of Clinical Oncology, or ASCO, is an organization that represents all clinical oncologists. Every year, ASCO holds a large symposium where physicians and researchers meet to convey and discuss research and ideas. (ASCO ASCO American Society of Clinical Oncology

Results show that both genes exhibit a significant correlation to positive clinical outcome, and together, identified three patient subgroups with significant differences in overall survival and progression-free survival. These data confirm the importance of ERCC1 as a predictor of response for platin-based chemotherapy. They also identify MDR1 as a promising biomarker to predict the outcome of adjuvant cisplatin/MTX-based adjuvant chemotherapy. This study provides the foundation for development of a new diagnostic test for improving chemotherapy of bladder cancer.

This study evaluated KRAS status and expression of genes involved in angiogenesis, DNA repair and 5-FU metabolism to identify predictors of outcome in patients treated with FOLFOX/BV or XELOX/BV. These genes included VEGF VEGF vascular endothelial growth factor. , VEGF-receptor 2, Cox-2, IL 6 and 8, chemokine-receptors 1 and 2, EGFR and ERCC-1. Results show that response rate (RR) and PFS were significantly longer for patients with wt KRAS, compared to patients with mutant KRAS. High EGFR, high VEGFR2 and low ERCC1 were associated with longer PFS, compared to low EGFR, low VEGFR2 and high ERCC1. To our knowledge, this is the first report showing an association between KRAS status, gene expression levels of VEGFR2, ERCC-1 and EGFR with clinical outcome to FOLFOX/BV therapy in patients with mCRC. These results suggest new gene combinations may help predict clinical benefit from chemotherapy of CRC (Cyclical Redundancy Checking) An error checking technique used to ensure the accuracy of transmitting digital data.

Abstract No: 4040: VEGF and VEGFR1 gene expression levels and tumor recurrence in adjuvant colon cancer.
Gene expression levels of angiogenesis regulators (COX-2, EGFR, VEGF, VEGFR1, VEGFR2 and IL-8) were tested to determine whether they could predict the risk of tumor recurrence in stage II and stage III colon cancer patients treated with adjuvant chemotherapy. Patients with lower VEGF gene expression and lower VEGFR1 gene expression levels had significantly longer time to tumor recurrence, compared to patients with higher VEGF and higher VEGFR1 gene expression levels. These results show that VEGF and VEGFR1 gene expression levels may predict tumor recurrence risk in colon cancer patients and help identify patients likely to benefit from adjuvant chemotherapy.
