Abstract

Insights

Over one-third of patients with resectable gastric cancer (GC) do not receive curative surgery. Insurance and hospital type significantly impact access to this vital treatment, highlighting disparities in care.

Area of Science:

  • Oncology
  • Surgical Oncology
  • Health Services Research

Background:

  • A significant proportion of patients with resectable gastric cancer (GC) do not undergo curative-intent surgery.
  • Understanding disparities and risk factors for failure to operate is crucial given national trends in GC surgical rates.

Purpose of the Study:

  • Identify disparities and targetable risk factors associated with the failure to perform surgery for resectable gastric cancer.
  • Analyze national trends in surgical rates for resectable GC.

Main Methods:

  • Utilized the National Cancer Database to identify patients with resectable GC (adenocarcinoma, clinical stage IA-IIIC) from 2004-2013.
  • Employed multivariate modeling to determine predictors of resection and assess the impact of surgery on overall survival (OS).

Main Results:

  • Of 46,970 patients, 39% did not receive surgery; 69% of unresected patients had no comorbidities.
  • Failure to resect was linked to reduced median OS (44.4 vs. 11.8 months, HR: 2.09, P < 0.001).
  • Key factors for no surgery included non-private/Medicare insurance, non-academic hospitals, non-Asian race, male sex, older age, higher comorbidity scores, lower income areas, smaller urban populations, and advanced stage.

Conclusions:

  • Over one-third of patients with resectable GC do not receive surgery.
  • Insurance status and treatment facility type are primary modifiable risk factors for omitting surgery.
  • Improving insurance coverage and regionalizing care are recommended to address national disparities in surgical access for GC.
