Disease-free survival · 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 disease-free survival (new disease, progression, and mortality) compared with therapeutic (delayed) neck dissection (moderate certainty).

Disease-free survival · Adults with oral cavity cancer
It is very uncertain whether elective radical (comprehensive) neck dissection changes disease-free survival (new disease, progression, and mortality) compared with elective selective neck dissection (very low certainty).
