Abstract The aim of this study is to determine the amino acid profile among the colorectal cancer patients. This is a prospective descriptive case-control study. This study includes 108 patients who underwent surgeries for colorectal carcinoma and 108 healthy control subjects during the period from1998 to 2003. The patients' data included: age, gender, pathological data and p53 expression. We performed the avidin-biotin complex immunoperoxidase method to detect bound p53 protein. An analysis with the Ion Exchange Chromatography was carried out for individual free amino acids. IgG antibodies against a low molecular weight fraction of H. pylori antigens were measured in duplicate with a validated in house indirect enzymelinked immunosorbent assay [ELISA]. Mean annual incidence was 3.1 patients / year. There were 74 males (68.5%) and 34 females (31.5%). The mean age at the time of diagnosis was 47.2 ± 9.7 years with the median age of 47 years. H. pylori serology was determined in all subjects. The sensitivity values for IgG and IgA H .pylori serology tests were 74% and 51% respectively (p 300 and > 250 respectively.
