Purpose
The aim of this study is to certify a rationality of Pathological Prognostic Score (PPS) in determining the prognosis of patients with colorectal carcinoma.
Methods
Three hundred and thirty‐one patients with colorectal carcinoma, which had been treated by surgical resection, were enrolled. One point was added for each element among four tumor‐related pathological factors of depth of tumor, lymph node metastasis, venous invasion, and lymphatic invasion. PPS was determined by an aggregate of the points.
Results
There existed a significant difference both between survivals of patients with PPS 0 or 1 and 2 or 3 (P = 0.0005) and between survivals of patients with PPS 2 or 3 and 4 (P < 0.0001).
Conclusions
PPS could be an easy and useful criteria to stratify prognosis of patients with colorectal carcinoma. J. Surg. Oncol. 2012; 106:243–247. © 2012 Wiley Periodicals, Inc.
