Golden ratio.

Number of nodes involved with head neck cancer is prognostic across primary sites, but it has so far been incorporated only into staging for the p16(+) variety. In the same vein, this retrospective look at 149 patients with oral cavity cancer demonstrated that a lymph node ratio (# involved nodes / # nodes dissected) of 10% was the strongest predictor of locoregional recurrence. | Ding, JAMA Otolaryngol Head Neck Surg 2018
