Effect of complication grade on survival following curative gastrectomy for carcinoma

Figure 1 Overall survival curves. A: Overall survival (OS) curves for all patients grouped by complication grade. The 5-year OS rates were 43.0%, 42.5%, 25.5% and 9.6% for no complications, and Grade I, Grade II and Grade III complications, respectively. There was no difference between Grade I complications and no complications (P = 0.882); B: OS curves for patients with TNM Stage II cancer. There were significant differences in OS among the three grades of complications in patients with tumor-node-metastasis (TNM) Stage II cancer (P < 0.001); C: OS curves for patients with TNM Stage III cancer. There were significant differences in OS among the three grades of complications in patients with TNM Stage III cancer (P = 0.001).
