Kaplan–Meier curves for overall survival (OS) after duodenal stent (DS) placement. (a) OS of all patients enrolled in this study. The median OS after DS placement was 81 (7–901) days. (b) OS according to stent types. No significant differences were observed. (c) OS according to a GPS of 0–1 or 2. The median OS for a patient with a GPS of 0–1 was significantly longer compared with that for a patient with a GPS of 2. (d) OS of patients with chemotherapy or best supportive care (BSC) after DS placement. The median OS of the chemotherapy group was significantly longer compared with that of the BSC group. (e) OS of patients with duodenal strictures in D1-2 or D3. The median OS of the D3 stricture group was significantly longer compared with that of D1-2 stricture group.
