| Variable | Overall survival |
|
|---|---|---|
| Hazard Ratio | Statistical significance | |
| Sex (male versus female) | 0.99 | NS |
| Age (>58 versus ≤58 years) | 1.01 | NS |
| CA 19-9 (>37 versus ≤37 ng/ml) | 1.03 | NS |
| γ-GGT (>50 versus ≤50 U/l) | 1.01 | NS |
| Tumour number (multiple versus single) | 1.49 | NS |
| Tumour size (>5 versus ≤5 cm) | 2.95 | NS |
| Tumour differentiation (well versus moderate versus poor) | 2.58 | NS |
| TNM stage (III–IV versus I–II) | 1.33 | NS |
| Lymph node metastasis (yes or no) | 1.53 | NS |
| PRC1 in tumour tissue (low or high) | 0.55 | P = 0.018 |
CA 19-9, carbohydrate antigen 19-9; γ-GGT, γ- Glutamyl transferase; TNM, tumour node metastasis; PRC1, protein regulator of cytokinesis 1.
NS, no statistically significant association (P > 0.05).
