There is an extensive body of research in complex cancer surgery that asserts a volume-outcome association in which patients are safer and have improved survival when their surgery is performed at hospitals and by surgeons with higher volume experience.^1,2 This volume-outcome relationship has been especially true after resection for pancreatic cancer.³ As a consequence, organizations have advocated for minimum-volume standards and, as such, a centralization of complex cancer surgery operations. However, concerns about decreasing access to complex cancer surgery have been raised.⁴ Given this concern, we modeled what an optimal location-allocation market for hospitals performing pancreatic resections would look like, with the goal of maximizing market share while minimizing cannibalization and eliminating low-volume centers.

在复杂的癌症手术中，有大量的研究表明，量结局的关联性使患者在医院进行手术并由经验丰富的外科医生进行手术时更加安全，并提高了生存率。^{1 ，2}这体积结果关系切除胰腺癌后更是如此。³因此，各组织提倡采用最小体积标准，并因此将复杂的癌症手术操作集中化。然而，已经引起了对减少进行复杂的癌症手术的机会的关注。⁴ 考虑到这种担忧，我们对进行胰腺切除术的医院的最佳位置分配市场进行了建模，目的是在最大程度地扩大市场份额的同时最大程度地减少自相残杀并消除小批量生产的中心。
