Does race affect the long-term survival benefit of systemic therapy in pancreatic adenocarcinoma?

Abstract

Background: Systemic therapy is a key management component of pancreatic ductal adenocarcinoma(PDAC). Racial disparities exist in PDAC, often linked to socioeconomic variables. We investigated the impact of race in PDAC patients who had undergone systemic therapy and surgical resection.

Methods: A retrospective analysis was performed for all patients who underwent surgical resection for PDAC from 2010 to 2018.

Results: 234 patients (78.2% White; 21.8% Black) were included. Black patients presented at a younger age with larger tumors. White patients benefited from systemic therapy with longer overall survival (35vs20 months, p = 0.002). This survival advantage was not present in Black patients (21vs15 months, p = 0.15). Black patients receiving systemic therapy had similar survival as White patients who did not (p = 0.81).

Conclusion: Black PDAC patients present at younger ages and with larger initial tumors. In our population, White patients had a longer overall survival after both surgical and systemic therapy. These findings may indicate differences in tumor biology. Further prospective studies are needed.
