Fig. 1. Kaplan-Meier and log-rank comparisons of DFS in patients with stage II/III gastric cancer according to (A) status of MSI and SPC-prognosis, (B) status of EBV and SPC-prognosis, (C) EBV status and treatment. DFS, disease-free survival; MSI, microsatellite instability; SPC, single patient classifier; MSS, microsatellite stable; MSI-L, microsatellite instability-low; MSI-H, microsatellite instability-high; EBV, Epstein-Barr virus; CTx, adjuvant chemotherapy (capecitabine plus oxaliplatin).
