Fig. 5From: Prognostic value of lymphovascular invasion in stage II colorectal cancer patients with an inadequate examination of lymph nodesThe 5-year overall survival (OS) rates among the different groups. We compared the OS rate among stage II patients with ≥ 12 ELNs; stage II LVI− patients with < 12 ELNs; stage II LVI+ patients with < 12 ELNs; and stages IIIA, IIIB, and IIIC patients. The 5-year OS rate of stage II LVI+ patients with < 12 ELNs was 60.4%, which is significantly lower than stage II LVI− patients with < 12 ELNs and stage II patients with ≥ 12 ELNs, respectively (60.4% vs. 75%, P < 0.001; 60.4% vs. 75.2%, P < 0.001). No significance existed among stage II LVI+ patients with < 12 ELNs and stages IIIA and IIIB (60.4% vs. 65.7% vs. 54.3 %, P = 0.052)Back to article page
