Biochemical study of Cancer Antigen CEA and CA 19-9 as prognostic markers in colorectal cancer (CRC)

Abstract

Colorectal cancer is one of the most common types of cancer in the world. Several factors have been shown to put individuals at risk to CRC and these include age, the presence of polyps, inflammatory bowel disease, lifestyle, genetic background and family medical history. In the present study, we were related to the cancer antigen CEA and CA19-9 as prognostic markers in colorectal cancer. This may be helping us to detect colorectal cancer in an early stage. In this study, we have included 60 patients diagnosed with colorectal cancer. These patients were categorized as 10 patients between stage I-IV with disease dissemination and recurrence; 50 patients in between stage I- IV without dissemination and recurrence; 60 healthy controls. The cancer antigen CEA and Ca 19-9 were analyzed as prognostic markers in colorectal cancer. The statistical analysis was done by using SPSS software and expressed in terms of mean ± standard deviation. The p values (p< 0.005) were considered as statistically significant value. Person correlation between the cancer antigen CEA and CA-19-9 were analyzed. The cancer antigen CEA and Ca19-9 level were significantly increased in colorectal cancer patients as compared to the healthy controls group (p< 0.005). The significant Person correlation was observed in between CEA and CA19-9. The level of CEA and CA19-9 were significantly prognostic indicator in colorectal cancer. CEA and CA19-9 can be used as a diagnostic and prognostic marker for the screening of both colon and rectum cancer.
