OBJECTIVE: To explore the importance of serum carcinoembryonic antigen level as a tumour marker in rectal carcinoma. METHODS: The retrospective study was conducted at Shaukat Khanum Memorial Cancer Hospital, Lahore, Pakistan, and comprised data of patients with rectal carcinoma from January 1996 to December 2015. Serum carcinoembryonic antigen levels were analysed using immulite@2000 system analyser. On the basis of serum carcinoembryonic antigen levels, data of patients was divided into four groups. Group A had normal serum levels both before and after surgical resection; Group B had normal levels pre-surgery but post-surgery levels were raised; Group C had raised levels pre-surgery that went down to normal post-surgery; and Group D had raised levels both before and after surgery. SPSS 23 was used for data analysis. RESULTS: Of the 401 patients, 267(66.6%) were males, and 204(50.9%) were aged <50 years. Group A had 267(66.6%) patients, Group B 26(6.5%), Group C 79(`9.7) and Group D had 29(7.2%) patients. Stage III disease was the most common 343(85.5%) and it was true across the groups. Overall recurrence was in 141(35.2%) patients. Group D had the highest recurrence rate 26(89.7%), while Group C had the lowest 18(22.8%). CONCLUSIONS: Fluctuating levels of carcinoembryonic antigen affected post-operative outcome.
