Contemporary Cancer Program Practice Profile Report Compliance Rates for Gastric Cancer: A National Cancer Database...

The Commission on Cancer (CoC) established quality measures to be reported in National Cancer Database (NCDB) Quality Reporting Tools. Compliance is provided to accredited cancer programs as Cancer Program Practice Profile Reports (CP3R). At the time of this study, the quality metric for gastric cancer (GC) was removal and pathologic examination of 15 regional lymph nodes for resected GC (G15RLN).

This study evaluates national trends in quality metric compliance for GC based on CoC CP3R.

The National Cancer Database (NCDB) was queried from 2004-2017 to identify patients with stage I-III GC who met criteria for inclusion. National trends in compliance were compared. Overall survival (OS) was compared stage for stage.

Overall, 42 997 patients with GC qualified. In 2017, 64.5% of patients met compliance with G15RLN compared to 31.4% in 2004. When comparing academic and non-academic institutions, compliance was met 67.0% vs 60.0% of the time in 2017 (P < .01) and 36% vs 30.6% of the time in 2004 (P < .01). On multivariate logistic regression, patients receiving care at academic institutions (OR 1.5, 95% CI 1.4-1.5) and who underwent surgery at institutions in the >75th percentile for case volume (OR 1.5, 95% CI 1.4-1.6) had higher odds of compliance. When stratified by stage, median OS was better across all stages when compliance was met.

Compliance rates with GC quality measures have improved over time. Compliance with the G15RLN metric is associated with improved OS, stage for stage. Continued efforts to improve compliance rates across all institutions are critical.
