were examined. Overall survival (OS) and disease-free survival (DFS) were evaluated using the Kaplan-Meier method and Log-Rank test. Univariate and multivariate analyses were performed for Combined P53 and Recombined P53 to determine independent factors. Three-year, two-year, and one-year OS and DFS were further analyzed using multimeROC. SPSS 27 and R 4.4.1 were used for analysis. Results: TNM stage, CA199, differentiation, tumor maximum size, and minimum size showed significant differences between the single P53 and S-CEA groups (all P < 0.05). TNM stage, CA199, and chemotherapy differed in both Combined P53 and Recombined P53 groups (all P < 0.05). Significant correlations were found between P53, S-CEA, Combined P53, and Recombined P53 (all P < 0.001). No significant differences in OS and DFS were observed with P53 and Combined P53 (all P > 0.05), but differences were noted with S-CEA and Recombined P53 (all P < 0.05). Univariate and multivariate analyses identified laparoscopy, chemotherapy, differentiation, TNM stage, and Recombined P53 as independent factors for OS and DFS, while P53, S-CEA, and Combined P53 were not. Further multimeROC analysis showed that 3-year OS had better sensitivity and specificity (Area Under Curve [AUC] = 0.54), and 1-year DFS was better (AUC = 0.59). Conclusions: Recombined P53 classification was more effective than traditional Combined P53 classification for assessing CRC prognosis and was an independent factor. Additionally, the 3-year OS and 1-year DFS analysis demonstrated higher sensitivity and specificity with Recombined P53.
