Very few studies have attempted to correlate long-term postesophagectomy survival with hospital case volumes. Rouvelas and colleagues take advantage of an unusual in-patient cancer registry, initiated in Sweden in 1987, that provided medical data for a cohort of 1199 patients with esophageal cancer operated on during a 14-year interval. High-volume hospitals performed 10 or more esophagectomies per year. There were 2 HVHs and 51 LVHs. Patient demographics, tumor stage, and tumor histology were closely matched for the 2 groups.
Operative mortality for HVHs and LVHs were 4% and 9%, respectively. This did not reach statistical significance (P = .09). Likewise, there was no statistical difference in the 30-day, 1-year, 3-year, or 5-year survival figures between the 2 groups. The authors conclude that hospital volume does not affect long-term survival.
This is a well-organized study taking advantage of a unique nationwide database with complete follow-up. Limitations include . . . [Full Text of this Article]
