Background
While anti-p53 antibody (p53-Ab) is a potential marker for early detection of colorectal cancer, its clinical utility in patients with advanced colorectal cancer remains unknown.
Methods
The clinical significance of p53-Ab was investigated by analyzing the data of 206 patients who underwent curative resection for colorectal liver metastases.
Results
Of the 206 patients, 60 (29%) were seropositive and 146 were seronegative for p53-Ab before the surgery. The preoperative serum p53-Ab level showed no significant correlation with the serum CEA or serum CA19-9 levels. The perioperative changes in serum p53-Ab positivity were significantly correlated with the preoperative serum p53-Ab levels and multivariate analysis confirmed that a higher preoperative p53-Ab level was independently associated with a worse recurrence-free survival (hazard ratio [HR], 1.07; 95% CI, 1.01–1.13; P = 0.033 per + 100 U/mL), even after adjustments for other oncological factors, including the preoperative serum CEA level.
Conclusion
Higher preoperative p53-Ab levels were associated with a higher risk of recurrence after curative resection of colorectal liver metastases.
