Elective neck dissection (at time of primary tumour resection) vs Therapeutic (delayed) neck dissection: Recurrence
- Population
- Adults with oral cavity cancer (tongue or floor of mouth) and clinically negative neck nodes
- Intervention
- Elective neck dissection (at time of primary tumour resection)
- Comparison
- Therapeutic (delayed) neck dissection
- Outcome
- Recurrence
Elective neck dissection (at time of primary tumour resection) probably leads to lower recurrence compared with therapeutic (delayed) neck dissection (moderate certainty).

How reviews are matched to this question
Reviews word the same question differently. Four decision models (TypeSafe's Jev, Liquid AI's d1-ultra, SubQ Snap and Baseten's Elephant) judged each wording of the population, intervention, comparator and outcome against the others; two wordings count as the same when at least three of them agree and none clearly disagrees, and findings count as this question only when all four elements match. Timing, setting and subgroup never split a question: they are shown on each finding.
