Core Tip

Core Tip: Patient related outcomes such as quality of life (QoL) are a focal endpoint of cancer treatments strategies. Many QoL Questionnaire (QLQ) are not trully validated. We aim to externally validate the Moroccan Arabic version of the European Organization for Research and Treatment of Cancer QLQ CR29 on larger and more heterogenous population in order to affirm its validity and reliability in arabic colorectal cancer patients.
