Purpose
We determined the usefulness of the estimation of physiologic ability and surgical stress (E-PASS), initially reported as a predictive factor for postoperative morbidity and mortality, as a prognostic indicator in stage II colorectal cancer (CRC).
Methods
Overall, 739 patients who underwent proctocolectomy for CRC at Tottori University Hospital and affiliated hospitals and histologically diagnosed with stage II CRC were included in the current study.
Results
A receiver operating characteristic (ROC) analysis of the five-year recurrence-free survival indicated that the comprehensive risk score (CRS) of E-PASS predicted postoperative recurrence. A multivariate analysis revealed that the presence of preoperative perforation, T4, v ≥ 2, and CRSHigh (≥ 0.2267) were independent predictors of postoperative recurrence. Patients were assigned a score using these factors, as follows: the presence of perforation = 1, the absence of preoperative perforation = 0, T4 = 1, T3 = 0, v2/3 = 1, v0/1 = 0, CRSHigh = 1, and CRSLow = 0 (total score: 0–4). Accordingly, the respective 5-year relapse-free survival rates were 91.0%, 83.6%, 70.3%, and 52.0% among those with scores of 0, 1, 2, and both 3 and 4 (P < 0.001).
Conclusions
The CRS predicts postoperative recurrence in patients with stage II CRC.
