Management of the N0 neck—reference or preference

SummaryFor patients with squamous cell carcinoma of the upper aerodigestive tract, appropriate management of the regional lymph nodes is an important and often controversial issue that has significant influence on survival. Over the years radical treatment either by surgery or radiotherapy contributed to improvement in prognosis. Recently, a more conservative approach has achieved a similar level of cancer control with less morbidity. This review considers the issues of selection of patients for treatment of the neck, choice of modality and extent of therapy, treatment of the contralateral neck, management of recurrence and influence of the site and status of the primary lesion.
