Patient-empowered Remote Oncology: the Prospective, Multicentre Implementation Study - the PROMISE

Primary Objective: To further develop and evaluate a personalised patient-centred surveillance programme including a feedback platform for patients after curative treatment for CRC in terms of health-related quality of life (HRQoL) and significantly decrease the number of in-hospital appointments, by relocating the follow-up care to the home-setting. The goal is for this surveillance program to be non-inferior to standard of care follow-up at 36 months, in terms of quality of life. The quality of life in patients will be assessed with the EQ 5D-5L questionnaire and compared to median EQ-5D-5L scores for patients receiving standard of care follow-up. In current literature, the median HRQoL VAS score for patients after surgery for CRC is 62.05 points (1).

The second goal of the program is to relocate part of the in-hospital follow-up care to the home-setting. In standard of care follow-up, at 36 months patients would have had 10 in-hospital appointments. The effect of the PROMISE study on the number of in-hospital appointments, will be assessed at 36 months postoperatively.

The PROMISE study is a multi-centre prospective regional implementation study of a personalised patient-centred surveillance program including a feedback platform for patients after curative treatment for CRC.

All patients who underwent surgery with curative intent for non-metastatic CRC with scheduled postoperative surveillance are potentially eligible.

Follow-up in this study is performed according to the acting Dutch national guidelines. Current guidelines advocate CEA level measurements to be performed every 3-6 months for first 2 years after surgery and every 6-12 months for years 3 to 5. Medical imaging (thoracic and abdominal CT) should be performed 1 year postoperatively. Changes to the Dutch national guidelines during the course of the study will be implemented accordingly into the follow-up.
