About this trial
The purpose of this study is to identify late adverse effects in colorectal cancer patients that may influence quality of life at 6, 12, and 24 months after oncological treatment. The study aims to assess quality of life in colorectal cancer survivors in relation to psycho-physical-social well-being at different time points and to evaluate the prevalence of late adverse effects and their association with diagnosis and specific oncological treatment.

Trial outcomes
Primary outcomes
Quality of Life Score (EORTC QLQ-C30 Global Health Status/QoL Scale)
Quality of life will be assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30), specifically the Global Health Status/Quality of Life scale (items 29 and 30). Scores will be linearly transformed to a 0 to 100 scale. Higher scores indicate better quality of life.
Secondary outcomes
Colorectal Cancer-Specific Quality of Life (EORTC QLQ-CR29)
Colorectal cancer-specific quality of life will be assessed using the EORTC QLQ-CR29 questionnaire. Scores will be linearly transformed to a 0 to 100 scale. Higher scores indicate better functioning for functional scales and worse symptoms for symptom scales.
