Long-Term Oncological Outcomes After Colorectal Anastomotic Leakage ; A Retrospective Dutch Population-based Study

Objective: The aim was to evaluate the impact of anastomotic leak (AL) after colon cancer (CC) and rectal cancer (RC) surgery on 5-year relative survival, disease-free survival (DFS), and disease recurrence. Background: AL after CC and RC resection is a severe postoperative complication with conflicting evidence whether it deteriorates long-term outcomes. Methods: Patients with stage I to IV CC and RC who underwent resection with primary anastomosis were included from the Netherlands Cancer Registry (2008–2018). Relative survival, measured from day of resection, and multivariable relative exce... Mehr ...
