Perioperative chemotherapy improves survival of patients with locally advanced diffuse gastric cancer

Figure 1 Kaplan-Meier survival curves for patients with diffuse gastric cancer receiving perioperative chemotherapy or surgery alone. A: The overall survival (OS) rates of patients who underwent perioperative chemotherapy or surgery alone; B: The cancer-specific survival (CSS) rates of patients who underwent perioperative chemotherapy or surgery alone; C: The OS rates of patients who underwent perioperative chemotherapy or surgery alone after inverse probability of treatment weighting (IPTW); D: The CSS rates of patients who underwent perioperative chemotherapy or surgery alone or surgery alone after IPTW. OS: Overall survival; CSS: Cancer-specific survival; IPTW: Inverse probability of treatment weighting.
