A study comparing different approaches in managing neck nodes in early carcinoma of the tongue

To evaluate elective neck treatment in patients with early stage (T1-2 negative neck node [N0]) squamous cell carcinoma of the oral tongue.

The medical records of all patients with early stage (T1-2 N0) of oral tongue cancer at the King Faisal Specialist Hospital and Research Center, Riyadh, Kingdom of Saudi Arabia, between January 1980 and December 1997, were identified and retrospectively reviewed.

Our cohort consisted of 93 patients: 45 males and 48 females, with a median age of 60 years. All patients received treatment with curative intent. Partial glossectomy was carried out, except for 8 patients who underwent tongue brachytherapy. The neck was observed in 29 patients, 36 were treated by modified neck dissection, and 28 by elective neck irradiation. With a median follow-up of 62 months, 29 patients had documented neck node recurrence. Ninety six percent (28/29) of recurrences occurred within 22 months from treatment completion. The 5 year actuarial event free survival with regard to nodal relapse in observed was 59%, dissected was 79% and irradiated neck was 63%. Our results showed a trend toward better neck node control in patients managed by elective neck dissection compared to those observed (p=0.07) or receiving elective neck irradiation (p=0.18). Tumor thickness of more than 10 mm was associated with increased risk of nodal relapse (p=0.0004). Neck node recurrence has a poor prognosis with a 5 year disease specific survival of 16%.

A trend for higher neck control was observed after neck dissection in patients with T1-2 N0 squamous cell carcinoma of the oral tongue. Elective neck dissection should be considered particularly for patients with tumor thickness of more than 10 mm.
