Treatment of contralateral N0 neck in early squamous cell carcinoma of the oral tongue: elective neck dissection versus observation.
Prophylactic treatment of contralateral N0 neck in early squamous cell carcinoma (SCC) of the oral tongue is a controversial issue. The aim of this study was to analyze the rates of occult metastases and their prognostic effects in stage I and stage II SCC of the oral tongue, and to compare the results of elective neck dissection to observation of the contralateral N0 neck in the treatment of these patients. ⋯ This study showed that ipsilateral elective neck management is indicated for stage I and II SCC of the oral tongue. On the other hand, our series suggests that contralateral occult lymph node metastasis was unlikely in early-stage oral tongue SCC, and that there was no survival benefit for patients who underwent elective neck dissection in place of observation. Thus, it may not harmful to observe the contralateral N0 neck in the treatment of early oral tongue cancer.
