Pdcd4 expression: 0^A, negative staining (score 1–2); 1^A, weak staining (score 3–4); 2^A, intermediate staining (score 5–6); 3^A, strong staining (score 7–8). N stage - N0, N1. Clinical stage: High, clinical stage I and II; Low, clinical stage I and II. Diff¹: W/M^a, well to moderate differentiation; P^b, poor differentiation; M^c, mucinous carcinoma. Diff²: Non-M¹, non-mucinous carcinoma; M², mucinous carcinoma.
