This study aimed to assess whether multidisciplinary team (MDT) management improves outcomes in patients with stage I–III colorectal cancer (CRC) compared to non-MDT care. This study included 460 CRC patients diagnosed from 2017 to 2018 in a northern Italian province, of whom 300 (65%) were managed by MDT. MDT patients were younger, more frequently had rectal cancers, were diagnosed at earlier stages, and were more likely to undergo surgery and chemotherapy. Disease-free survival (DFS) and overall survival (OS) were significantly better in the MDT group. The recurrence rate was 8.5%, with no significant differences between MDT and non-MDT patients, although MDT patients exhibited lower recurrence rates for early-stage tumors. A multivariable analysis showed that DFS and OS were adversely affected by older age, advanced stage, and lack of MDT management. Kaplan–Meier estimates demonstrated a 3-year DFS of 78% in the MDT group versus 65% in the non-MDT group, as well as an OS of 83% versus 69%, respectively. The MDT approach was associated with improved treatment adherence and better management of recurrences. While limited by a small sample size, this population-based study highlights the beneficial impact of MDT care on CRC outcomes. Further research with extended follow-up is warranted to confirm these findings.
