Resection

To remove a brain tumor, patients usually receive radiation to lower the chance that the cancer will come back in the spot where the tumor was removed.

This international multicentre retrospective cohort study aims to research anastomotic leakage after colon cancer resection and has two main objectives: 1. To identify predictive factors associated with 90-day mortality and 90-day Clavien-Dindo grade 4-5 complications amongst patients who developed AL following colon cancer resection and to develop and validate a prediction model for predicting 90-day mortality as well as the co-primary composite endpoint Clavien-Dindo grade 4-5 complications. 2. To explore and compare the effectiveness of various treatment strategies for AL following colon cancer resection, considering patient, tumour, resection and leakage characteristics.
