From: Prognostic Impact of the Signet Ring Cell Type in Node-Negative Gastric Cancer
Kaplan-Meier survival curves comparing the years of overall survival in signet ring cell (SRC) and non-SRC gastric carcinoma are shown for (a) perineural invasion-positive tumours (non-SRC: 164 v SRC: 48), (b) perineural invasion-negative tumours (non-SRC: 226 v SRC: 42), (c) vascular invasion-positive tumours (non-SRC: 42 v SRC: 13), and (d) vascular invasion-negative tumours (non-SRC: 348 v SRC: 77).
