Abstract:
Objective To investigate the relationship among CEA, CA199, clinical pathological characteristics and prognosis in patients with rectal cancer. Methods A total of 142 patients diagnosed rectal cancer were collected for the study between January 2006 and December 2010. The clinical data including age, sex, size of tumor, differentiation, depth of tumor (T), lymph node metastasis (N), distant metastasis (M), lymphatic invasion, venous invasion, stage, and preoperative serum levels of CEA and CA199 were obtained. Patients′ follow-up ranged from 42 months to 90 months. Results Preoperative elevated CEA levels were significantly associated with distant metastasis (P < 0.05). Median overall survival time was 150 weeks in the group with normal preoperative CEA and CA199, and 101 weeks in the group with preoperative abnormal preoperative CEA and/or CA199, and Kaplan-Meier analysis showed that the difference was significant between two groups (P = 0.031). Conclusion Elevated preoperative CEA level can predict distant metastasis. The patients with abnormal preoperative CEA and/or CA199 have shorter overall survival time.
