TL;DR: The proposed system for defining and recording perioperative complications associated with esophagectomy provides an infrastructure to standardize international data collection and facilitate future comparative studies and quality improvement projects.

TL;DR: Patients with early cancers had worse survival and those with advanced cancers better survival than expected from equivalent pathologic categories based on prior WECC pathologic data, making clinically based treatment decisions difficult and pre-treatment prognostication inaccurate.

TL;DR: In esophageal cancer, pN+, increasing number of positive nodes, and increasing pN classification are associated with deeper invading, longer, and poorly differentiated cancers, so few nodes need to be removed if the goal of lymphadenectomy is to accurately define pN+ status of such cancers.

TL;DR: Detailed descriptions of patient characteristics, cancer categories, and non-risk-adjusted survival-for patients with pathologically staged cancer of the esophagus and esophagogastric junction after resection or ablation with no preoperative therapy from the Worldwide Esophageal Cancer Collaboration are reported.

TL;DR: Data-simple descriptions of patient characteristics, cancer categories, and non-risk-adjusted survival-for pathologically staged cancers after neoadjuvant therapy from the Worldwide Esophageal Cancer Collaboration will be the basis for the 8th edition cancer staging manuals following risk adjustment for patient, cancer, and treatment characteristics.
