Research Abstract

The aim of this study was to analyze in the serum of nude mice that were implanted colorectal cancer cells and in the serum of colorectal cancer patients using Alu DNA sequences (Alu247 and Alu115) and to reveal whether Alu247/Alu115 ratio (Alu ratio) is related to outcome of treatments and to clinical-oncological factors. We concluded that the Alu ratio might be useful for predicting effects of chemotherapy and for discriminating between cancer and non-cancer. The Alu ratio was considered to have a higher discriminatory ability for diagnosing cancer than the CEA and CA19-9 tumor marker levels.
