Underlying Bias in the Treatment of Pancreatic Cancer

Minorities Treated at the Same Facilities are Less Likely to Receive Neoadjuvant Therapy

Abstract

Objective: 

To identify disparities in access to NAT for PDAC at the prehospital and intrahospital phases of care.

Summary of Background Data: 

Delivery of NAT in PDAC is susceptible to disparities in access. There are limited data that accurately locate the etiology of disparities at the prehospital and intrahospital phases of care.

Methods: 

Retrospective cohort of patients ≥18 years old with clinical stage I-II PDAC from the 2010–2016 National Cancer Database. Multiple logistic regression was used to assess 2 sequential outcomes: (1) access to an NAT facility (prehospital phase) and (2) receipt of NAT at an NAT facility (intrahospital phase).

Results: 

A total of 36,208 patients were included for analysis in the prehospital phase of care. Higher education, longer travel distances, being treated at academic/research or integrated network cancer programs, and more recent year of diagnosis were independently associated with receipt of treatment at an NAT facility. All patients treated at NAT facilities (31,099) were included for the second analysis. Higher education level and receiving care at an academic/research facility were independently associated with increased receipt of NAT. NonBlack racial minorities (including American Indian, Asian, Pacific Islanders), being Hispanic, being uninsured, and having Medicaid insurance were associated with decreased receipt of NAT at NAT facilities.

Conclusions: 

Non-Black racial minorities and Hispanic patients were less likely to receive NAT at NAT facilities compared to White and non-Hispanic patients, respectively. Discrepancies in administration of NAT while being treated at NAT facilities exist and warrant urgent further investigation.
