Introduction:
Regionalizing hepatic resections to high-volume hospitals (HVH) has improved outcomes, yet widened disparities in access. We sought to evaluate the association of hospital volume with quality care outcomes and overall survival (OS) between minor and major hepatectomy for primary liver cancer.
Methods:
The National Cancer Database identified patients with primary liver cancer who underwent minor/major hepatectomy (2009-2019). HVHs were defined by the top quartile in annual case volume (vs. the bottom three quartiles). Quality care outcomes (time to resection, margin status, length of stay, 30-day readmission, 30-day mortality, 90-day mortality) and OS were assessed using multivariable regression.
Results:
Overall, 6,988 patients underwent minor hepatectomy and 4880 major hepatectomy. No differences in quality care outcomes or OS based on hospital volume for minor hepatectomy were observed (all p > 0.05). Treatment at HVHs for major hepatectomy was associated with decreased odds of 30-day and 90-day mortality events (all p < 0.05). Median OS was 40.2 months [IQR 21.7-66.6] at HVHs versus 33.5 [IQR 17.0-58.7] at low-volume hospitals which remained independently predictive of improved OS on multivariable analysis (HR 0.86, 95% CI 0.79-0.93).
Conclusion:
These results support regionalization to HVHs for major hepatectomy; however, minor hepatectomy can be safely performed at hospitals regardless of volume.
