Table 3.
The relationship between surgical radicality and survival n (%)
| Surgical radicality | Cases with follow-up | 1-yr survival | 3-yr survival | 5-yr survival |
| R0 resection (n = 49) | 47 | 26 (55.3)b | 15 (31.9)b | 5 (10.6)b |
| R1 + R2 (palliative) resection (n = 22) | 21 | 2 (9.5)b | 0 | 0 |
| Bypass or laparotomy (n = 49) | 48 | 6 (12.5)b | 0 | 0 |
| Non-surgical treatment (n = 94) | 81 | 1 (1.2)b | 0 | 0 |
| Total (n = 214) | 197 | 25 (12.7) | 15 (7.6) | 5 (2.5) |
b
P < 0.01 vs non-R0 resection, the 1-, 3- and 5-year survival rates were significantly longer.
