LAPTM4B and metastatic malignant neoplasm in the lymph nodes: The results of univariate and multivariate Cox’s models for OS of GC patients in TNM Stage I-III exhibited that depth of invasion (RR = 3.103, 95% CI: 1.427–6.748; P = 0.004), lymph node metastasis (RR = 3.015, 95%CI: 1.552–5.858; P = 0.001) and LAPTM4B-35 expression level (RR = 2.249, 95%CI: 1.242–4.072; P = 0.007) significantly affected the survival of GC, respectively (Table 3); furthermore, LAPTM4B-35 positive expression was an independent prognostic factor (RR = 1.897, 95%CI: 1.041–3.457; P = 0.025).
