CRP and neoplasm: As shown in Table 3 (right panel), Poor tumor differentiation, late T stage, late N stage, history of smoking, higher postoperative CRP, lower postoperative Alb, higher preoperative CRP/Alb ratio (HR 1.42, 95% CI 1.08–1.87, P = 0.012) and higher postoperative CRP/Alb ratio (HR 1.72, 95% CI 1.29–2.30, P < 0.001) were associated with poor DFS.
