Researchers are studying patients diagnosed with colorectal cancer, small bowel cancer, and anal cancer to better understand factors that affect treatment outcomes and survival. This study looks beyond tumor stage to explore how biochemical, genetic, environmental, and clinical factors may influence tumor recurrence and patient survival. It aims to address the gap in knowledge caused by most cancer patients not participating in clinical trials, and to validate trial results in a broader patient population. This is a prospective observational cohort study where data is collected from patients starting at their primary diagnosis and continuing until death. After informed consent, researchers gather detailed information on medical history, clinical status, imaging, pathology, tumor characteristics, treatments, hospital stays, side effects, and adverse events. Additional consent allows collection of patient-reported outcomes on quality of life and work ability, as well as biological materials like blood and tumor tissue for research and biobanking. Participants will be closely followed over time with ongoing data collection on treatment effects, clinical outcomes, and patient experiences. The study aims to provide accurate real-world data on various treatments and outcomes and to serve as a resource for future research into prognostic markers, new therapies, molecular studies, and health care policy. The main outcome measured is progression-free survival, tracked for up to 10 years, to better understand long-term treatment impact.
