Locally advanced rectal cancer: New insights for a tailored approach

By implementation of MRI-based staging, selective preoperative radiotherapy and surgical resection according to the TME-principle, the outcomes for patients with locally advanced rectal cancer have improved considerably over the last decades. This has led to an increased focus on quality of life, functional outcomes and shared decision making. In this thesis, novel treatment options for patients with locally advanced rectal cancer are evaluated, including watch and wait for patients with a complete response after chemoradiotherapy as well as a total neoadjudant therapy (TNT) approach. Also quality of life and the importance patients assign to several outcome measures after ungoqing treatment for rectal cancer themselves are described.
