SRC and gastric neoplasm: In univariate analysis, age >60 (p = 0.000), whole stomach tumor (p = 0.004), SRC proportion 1–50% (p = 0.021), SRC proportion >50% (p = 0.000), total or combined organ gastrectomy (p = 0.000, 0.017, respectively), Borrmann's type IV (p = 0.000), pT stage (p = 0.029, 0.016, 0.002, respectively), pN stage (p = 0.014, 0.000, 0.000, respectively), pTNM stage (p = 0.000), lymphovascular invasion (p = 0.000), and perineural invasion (p = 0.015) were prognostic factors for OS (Table 2).
