BACKGROUND AND OBJECTIVE
Precise evaluation of the prognostic factors for hematogenic recurrence after resection for colorectal cancer is important not only for the prediction of patient outcome but also for the determination of adjuvant therapy. The purpose of the current study was to elucidate the clinical significance of using clinicopathological variables in combination with p53 expression as a prognosticator for hematogenic recurrence.
METHODS
One hundred forty-two patients with colorectal cancer were examined. The expression of p53 was determined by immunohistochemical staining.
RESULTS
Eighteen (60%) of the 30 patients who were positive for both p53 overexpression and lymph node metastasis, 13 (41%) of the 32 patients who were positive for p53 and venous invasion, and 13 (39%) of the 33 patients who were positive for p53 and carcinoembryonic antigen (CEA) developed hematogenic recurrence.
CONCLUSIONS
The combination of p53 overexpression and lymph node metastasis was an excellent prognostic indicator for hematogenic recurrence in colorectal cancer.
