Abstract
BACKGROUND: The clinical impact of monitoring serum p53 antibodies, carbohydrate antigen19-9, and carcinoembryonic antigen in patients with colorectal cancer has not been fully evaluated. METHODS: A total of 420 surgically treated stage II/III colorectal cancer patients were retrospectively analyzed. Among them, 101 patients developed disease recurrence. The prognostic impact of preoperative and recurrence levels of serum p53 antibodies, carbohydrate antigen19-9, and carcinoembryonic antigen status was evaluated. RESULTS: Although preoperative carcinoembryonic antigen- and carbohydrate antigen19-9-positive status was significantly associated with recurrence, preoperative serum p53 antibody levels were not. Among two marker combinations, carcinoembryonic antigen + serum p53 antibodies showed the highest positive rate at recurrence. Although carcinoembryonic antigen and carbohydrate antigen19-9 frequently converted from preoperative-negative status to positive status at recurrence, serum p53 antibodies converted to positive status in only one patient. Carcinoembryonic antigen- and carbohydrate antigen19-9-positive status were significant prognostic factors for overall survival after recurrence, but the presence of serum p53 antibodies at recurrence was not. CONCLUSIONS: Postoperative serum p53 antibody status should only be followed in patients with preoperative-positive status. Carcinoembryonic antigen and carbohydrate antigen19-9 should be followed even in preoperative-negative patients. Unlike carcinoembryonic antigen- and carbohydrate antigen19-9-positive status, serum p53 antibody-positive status as recurrence was not a poor prognostic indicator.
