Prognostic value of perioperative leukocyte count in resectable gastric cancer

Figure 1 Kaplan-Meier curves depicting overall survival. A: Patients with higher preoperative white blood cell count (WBC) had shorter overall survival (OS) when divided by the median; B: Patients affected by p-leukopenia had worse OS; C: Patients whose WBC < 4.0 × 10⁹/L after surgery had lower OS than those whose WBC ≥ 4.0 × 10⁹/L; D: Combined analysis of OS by pre- and postoperative WBC. Patients with low preoperative WBC but without p-leukopenia showed the optimal OS, significantly longer than that in patients who had both high preoperative WBC and p-leukopenia.
