AFAP1 and gastric cancer: Clinical grade (HR = 1.912, 95% CI: 1.246–2.934, p = 0.003), pathologic tumor node metastasis (pTNM) (HR = 2.393, 95% CI: 1.431–4.033, p = 0.001), log odds of positive lymph nodes (LODDS) (HR = 2.910, 95% CI: 1.787–4.793, p  <  0.001) and AFAP1‐AS1 expression (HR = 2.393, 95% CI: 1.869–3.064, p  <   0.001) were independent prognostic factors for GC revealed by multivariate Cox‐regression analysis.
