Multivariate Cox Stepwise Proportional Hazard Model for overall survival in 100 EGC and 741 AGC patients with gastrectomy
| Stage | Variable | χ 2 | P | Hazard ratio (95% CI) |
|---|---|---|---|---|
| EGC | Lymph node metastasis | 6.236 | 0.013 | 7.138 (1.526, 33.378) |
| AGC | Age | 12.542 | < 0.001 | 1.019 (1.009, 1.030) |
| Tumor size | 10.909 | 0.001 | 1.552 (1.196, 2.014) | |
| Lymph node metastasis | 55.555 | < 0.001 | 1.498 (1.347, 1.6663) | |
| Depth of invasion (T2-T4) | 17.750 | < 0.001 | 1.570 (1.273, 1.936) | |
| Histology | 4.820 | 0.028 | 1.177 (1.018, 1.361) |
EGC: early gastric cancer. AGC: advanced gastric cancer.
