Case volume regionalization and volume‐based outcome differences in cutaneous head and neck melanoma

Abstract

Background

Hospital volume has emerged as a prognostic factor in oncology but is not currently known whether volume is associated with improved outcomes for cutaneous head and neck (HN) melanoma.

Methods

A total of 556 079 cutaneous melanoma cases reported by the 2004–2016 National Cancer Database were separated into two cohorts (HN and non-HN) and facilities within each cohort were classified by case volume. Analysis employed chi-square, analysis of variance, Kaplan–Meier, and Cox proportional hazards models.

Results

Only 41 facilities (3.1% of 1326) treating HN melanoma and 50 facilities (3.7% of 1344) treating non-HN melanoma were classified as high-volume facilities (HVFs). The estimated 5-year overall survival (OS) was 62.7% (standard error [SE]: 0.4%) for patients with HN at low-volume facilities (LVFs), 69.3% (SE: 0.4%) at IVFs, and 71.8% (SE 0.4%) at HVFs (p < 0.001). Differences in OS remained significant between HVFs versus LVFs after adjusting for confounders.

Conclusion

Volume is independently associated with OS and improved surgical outcomes for HN melanoma.
