a DFS and b OS between patients with mild to moderate complications (n = 10, solid line) and severe complications (n = 3, dotted line). The median DFS in patients with mild to moderate complications was not reached, and that in patients with severe complications was 7 months (p = 0.001). The MST of patients with mild to moderate complications was not reached, whereas that of patients with severe complications was 15 months (p < 0.001). DFS, disease-free survival; OS, overall survival
