摘要

Purpose

Multidisciplinary tumor boards (MTBs) intend to increase the quality of cancer care. Research on the association of adherence to MTB recommendations with survival is limited. This study aims to determine the impact of adherence to MTB recommendations on survival in colorectal cancer patients.

Methods

This is a retrospective, observational study including patients diagnosed between 01.01.2014 and 31.12.2018. Electronic health records were reviewed to determine the adherence. Study endpoints were adherence rate, disease-free survival (DFS), and overall survival (OS). Follow-up was performed until 12.12.2023.

Results

There was a significant difference in DFS (median DFS: 79 months [95% CI, 73-89] vs 22 months [95% CI, 17-87]) and OS (median OS: 78 months [95% CI, 75-86] vs 65 months [95% CI, 28-NR]) between the adherent group (n=406) versus the non-adherent group (n=52) (log-rank test, p<0.05). Performance status, stage and non-adherence were independent predictors of survival in the multivariate analysis (p<0.05 for all). The most common reason for non-adherence was patient preference (n=23).

Conclusion

While MTBs have become an indispensable part of clinical practice, adherence to MTB recommendations was crucial to achieve survival benefit in this study. Patient preference should be prospectively analyzed from a patient and caregiver perspective in future studies.
