Background: The prevalence of esophagogastric varices (EGV) in patients with advanced pancreatic cancer is not rare. However, its clinical significance has never been investigated. This study was aimed to explore the clinical implication and outcomes of these patients.
Methods: A retrospective analysis comprising 224 patients with advanced pancreatic cancer managed from October 2012 to December 2019 at a tertiary medical center identified 35 patients who had presented with EGV. Clinical characteristics and outcomes were analyzed with special emphasis on comparison between patients with early-onset and late-onset EGV.
Results: Patients with EGV had lower platelet count and a higher proportion of splenomegaly but no difference in overall survival in comparison to those without EGV. Patients with early-onset EGV had a poorer bleeding survival (hazard ratio, 8.347; CI, 2.509-27.772; p = 0.001) in comparison to those with late-onset EGV. On multivariate analysis, initial serum bilirubin, γ-Glutamyltransferase, lactate dehydrogenase, cancer stage, and the response to cancer treatment determine the patient's survival. Patients with tumor invasion to superior mesenteric and portal vein are more likely to have esophageal varices (EV) (EV: 13/15 vs gastric varices [GV]: 4/20; p < 0.001); those with splenic vein invasion are more likely to have GV (EV: 4/15 vs GV: 20/20; p < 0.001).
Conclusion: Patients with advanced pancreatic cancer and early-onset EGV had poorer bleeding-free survival than those with late-onset EGV. Further studies are needed to clarify the benefits of the prophylactic intervention.
