Clinical outcomes of tumor bleeding in duodenal gastrointestinal stromal tumors: a 20-year single-center experience

Abstract
Background: Duodenal gastrointestinal stromal tumors (GISTs) are rare, and reports on duodenal GIST bleeding are few. We analyzed the risk factors and clinical outcomes of hemorrhagic duodenal GISTs and compared them with those of gastric GISTs. Methods: Primary duodenal GISTs surgically diagnosed between January 1998 and December 2017 were retrospectively reviewed. Furthermore, patients with duodenal GIST were compared with those with primary gastric GIST histopathologically diagnosed between January 1998 and May 2015 using previously published data. Results: Of the 170 total patients with duodenal GISTs, 48 (28.2%) exhibited tumor bleeding. Endoscopic intervention, embolization, and non-interventional conservative treatment were performed for initial hemostasis in 17, 1, and 30 patients, respectively. The 5-year survival rate was 81.9% in the bleeding group and 89.4% in the non-bleeding group (P = 0.495). Multivariate analysis showed that p53 positivity was a significant risk factor for duodenal GIST bleeding (hazard ratio [HR] 2.781, P = 0.012), and age ≥ 60?years (HR 3.163, P = 0.027), a large maximum diameter (comparing four groups: < 2, 2?5, 5?10, and ≥ 10?cm), and mitotic count ≥ 5/high-power field (HPF) (HR 3.265, P = 0.032) were risk factors for overall survival. The incidence of bleeding was significantly higher in duodenal GISTs than in gastric GISTs (28.2% vs. 6.6%, P < 0.001), and the re-bleeding rate after endoscopic hemostasis was also higher in duodenal GISTs than in gastric GISTs (41.2% vs. 13.3%, P = 0.118). Conclusion: In patients with duodenal GIST with old age, large tumor diameter, and mitotic count ≥ 5/HPF, a treatment plan should be established in consideration of the poor prognosis, although tumor bleeding does not adversely affect the prognosis. Duodenal GISTs have a higher incidence of tumor bleeding and re-bleeding rate after endoscopic hemostasis than gastric GISTs.
