Prognostic significance of 14v-lymph node dissection to D2 dissection for lower-third gastric cancer

Figure 1 Overall survival curves of patients. A: Overall survival curves of patients in the 14vD (-) and 14vD (+) groups; B: Overall survival curves of patients in the 14vD (-) group, the 14vD (+) group with and without 14v lymph nodes metastasis, and patients with distant metastasis. LNM (-): Without 14v lymph nodes metastasis; LNM (+): With 14v lymph nodes metastasis.

Figure 2 Forest plot of overall survival. The hazard ratios for adding 14v lymph node dissection were obtained via Cox proportional hazard model for pathologic T stage and pathologic N stage.

Figure 3 Overall survival according to 14v lymph node dissection in gastric cancer patients. A: Pathologic stage I; B: Pathologic stage II; C: Pathologic stage IIIA; D: Pathologic stages IIIB/IIIC gastric cancer patients.
