Total mortality: 2 trials reported HR but could not be pooled (different surgical procedures); neither indicated a difference (BHNCSG 1998 HR 1.14, 0.70 to 1.86; Bier 1994 HR 0.87, 0.41 to 1.83); 252 participants (2…

Locoregional recurrence · Adults with oral cavity or oropharyngeal cancer

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