Effective teams require a minimal size to cover needed disciplines; size increases as the complexity of the tumor treatment increases and management focus broadens. However, larger teams are generally more difficult to coordinate, and thus, larger size tends to correlate with poorer team performance and patient outcomes (27). It is also worth considering how the presence of nonspecialty care MDs might create more challenges than added value to the MDC team process, particularly when team size approaches 10 or more members, when not all members are relevant to a given discussion, and when team membership may not be constant across the treatment process.
