Incorporation of perigastric tumor deposits into the TNM staging system for primary gastric cancer

Figure 6 Comparison of survival curves of patients with different tumor deposit locations and with those of patients without tumor deposits with different TNM pathological stages. A: Comparison of Kaplan-Meier (K-M) curves of patients with tumor deposits (TDs) appearing in the gastric body with pathological stage of T without TDs; B: Comparison of K-M curves of patients with TDs appearing in the lesser curvature with pathological stage of N without TDs; C: Comparison of K-M curves of patients with TDs appearing in the greater curvature with pathological stage of M (pM) without TDs; D: Comparison of K-M curves of patients with TDs appearing in distant tissue with pM without TDs. TDs: Tumor deposits; pT: Pathological stage of T; pN: Pathological stage of N; pM: Pathological stage of M.
