The aim of this study is to evaluate the adherence of postoperative colorectal cancer patients using a digital follow-up platform. The primary endpoint is follow-up rate at 3 months after surgery. The secondary endpoints are: follow-up rate at 6, 9, and 12 months, adherence during 12 months, medication adherence (MMS-4), the number and reasons for alerts triggered by patients, the frequency and reasons for patient-initiated report, quality of life (FACT-C), patient satisfaction (FACIT-TS-PS), the system's usability (SUS), the monitoring rates of imaging exams, colonoscopies, and CEA markers at 3, 6, 9, and 12 months will be analyzed. Differences in clinical outcomes: progression-free survival, overall survival, adverse events, the incidence of complications, hospital admissions (unplanned hospital visit rates, average unplanned hospital stay duration, and potentially preventable emergency visits) are additional outcomes.
