Regionalization of oncologic care has increased, but less is known whether patient outcomes are influenced by receipt of multimodality care through multicenter care (MCC) or single-center care (SCC).
Patients from 2004 to 2015 National Cancer Data Base diagnosed with stage II-III esophageal (EA), stage II-III pancreatic (PA), and stage II-IV rectal (RA) adenocarcinoma who underwent resection at a high volume center (HVC) and required radiation and/or chemotherapy were included. MCC (care at 2+ facilities) and SCC patients were propensity-score matched 1:2 and Cox proportional hazards regression used to analyze survival.
On multivariable regression analysis, MCC in RA patients (N = 325/2097, 15.5%) was more associated with residing ≥40 miles from the HVC (odds ratio [OR] = 2.37; P = .044) and receipt of neoadjuvant chemotherapy (1.42, P = .040). In PA patients (N = 75/380, 19.7%), residing ≥40 miles from the HVC (OR = 3.22; P = .001), and in EA patients (N = 88/534, 16.5%), younger patients (<50 years: OR = 2.96; P = .011) were associated with MCC. Following propensity score matching, EA (N = 147), PA (N = 133), and RA (N = 661) patients had no difference in 1-year and 3-year overall survival when comparing MCC to SCC.
The use of MCC appears safe without a difference in survival and may offer significant advantages in convenience to patients as they undergo their complex oncologic care.
