As the available literature implies that intensive postoperative surveillance has no impact on (cancer-specific) survival outcomes in patients after curative intent surgery for CRC, critical appraisal of the current follow-up practice and guidelines is needed. Although patients in the referenced randomized controlled trials were included roughly 5 - 15 years ago, treatment for recurrent colorectal cancer has seen little to no change since then. Therefore, efforts to improve the current standard of follow-up in patients with CRC should focus on ameliorating quality of life and cost-effectiveness, rather than survival. It provides an opportunity to support patients emotionally, to evaluate treatment effects and complications, and to inform them on their individual prognosis. This is especially true considering the growing importance of value based healthcare and patient reported outcomes in medicine. The investigators therefore propose a patient-led home-based follow-up approach. This follow-up strategy primarily consists of carcinoembryonic antigen (CEA) level monitoring at home, but additional counselling/diagnostic testing remains possible if desired by patients. In this way the investigators hope to meet the individual needs of patients during follow-up and to improve quality of life outcomes, while achieving equal or greater societal cost-effectiveness.
The currently developed implementation study aims to evaluate if a patient-led home-based follow-up approach is successful, improves quality of life, reduces anxiety and lessens fear of cancer recurrence during the years after surgical treatment of colorectal cancer (CRC).
