ENT · Oral cavity: nodal levels in tongue cancer
Sample itemIn carcinoma of the oral tongue, which cervical lymph node levels are most commonly involved?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
C. Levels I to III
The oral cavity drains primarily to levels I, II and III, so selective neck dissection of levels I to III or IV is used for elective management. Skip metastasis to level IV can occur in tongue cancer.
Option by option
A. Level V only
Level V is rarely the first site.
B. Level VI only
Level VI drains the thyroid and subglottic larynx.
C. Levels I to III (correct)
Correct. Levels I to III are the primary echelon.
D. Retropharyngeal nodes only
Retropharyngeal nodes drain the nasopharynx.
