Prognostic value of signet-ring cell carcinoma proportion in undifferentiated gastric cancer: Implications for endoscopic treatment decisions

Figure 5 Association of signet ring cell carcinoma rates with prognostic factors in early-stage gastric cancer with undifferentiated-type histology. A: Signet ring cell carcinoma (SRCC) rates according to lymph nodal metastasis; B: SRCC rates according to presence of ulcer; C: SRCC rates according to tumor size; D: SRCC rates in early-stage gastric cancer subgroup; E: Submucosal invasion depth (μm) according to SRCC group; F: SRCC rates according to submucosal invasion level. SRCC: Signet ring cell carcinoma; EGC: Early-stage gastric cancer.
