| Stage IVA (n = 34) | 18 (52.9)2 | 7 (20.6) | 9 (26.5) |
| Stage IVB (n = 53) | 0 | 13 (24.5) | 40 (75.5) |
b
P < 0.01 vs R1 + R2 resection and bypass or laparotomy;
1
Peri-organ involvement included spleen, transverse colon, left kidney, stomach and their vessels;
2
Six gastric malignant tumors with pancreatic invasion, one pancreatic metastasis from renal cell carcinoma after operation, 11 pancreatic cystadenocarcinomas with splenic invasion.
