AIM: Duodenal gastrointestinal stromal tumors (GISTs) constitute a small rare subset. This study aims to analyze the prognostic differences between duodenal and jejunoileal GISTs and evaluate the clinical treatment and prognostic characteristics of patients with duodenal GISTs.
METHODS: Data of patients with primary duodenal or jejunoileal GISTs were collected. Patients were matched through propensity score matching (PSM). Perioperative and long-term outcomes of patients with duodenal GISTs were compared based on surgical approach.
RESULTS: Altogether, 101 duodenal and 219 jejunoileal GISTs were identified. In patients with duodenal GISTs, 79 (78%) underwent local resection (LR) and 22 (22%) underwent pancreaticoduodenectomy (PD). Patients undergoing PD had a longer postoperation stay (18.5 vs 13 days, P = 0.001) and more complications (Clavien-Dindo I-II complications for PD vs LR, 31.8 vs 15.2%; Clavien-Dindo III-V complications for PD vs LR, 22.7 vs. 2.5%; P < 0.001). There was no difference in recurrence-free survival (RFS) (P = 0.8) or overall survival (OS) (P = 0.9) when comparing patients who underwent LR versus PD. Multivariable analysis showed that tumor size >5 cm was the only independent predictor of shorter RFS (P = 0.004) and OS (P = 0.012). After matching, there was no significant difference in RFS and OS between patients with duodenal versus jejunoileal GISTs (both P > 0.05).
CONCLUSION: The prognosis of duodenal and jejunoileal GISTs are similar. Recurrence and OS of duodenal GISTs primarily depend on tumor size. For duodenal GISTs, LR is associated with comparable long-term survival when compared to PD, but with superior short-term outcomes.
