Objective. To evaluate site of regional recurrence in patients with squamous cell carcinoma of upper aerodigestive tract after neck dissection and the results of salvage treatment. Methods. 95 patients with regional recurrence as the first manifestation of relapse were selected between 943 patients who underwent neck dissection. We evaluated level and side of recurrence, as well disease control after salvage treatment. Results. Level II was the most frequent site of recurrence. Salvage treatment was performed in 51% of ipsilateral and in 75% of contralateral (nondissected neck) recurrences. Control of the disease 12 months after salvage surgery was 25% in the ipsilateral and 37% in contralateral recurrences. Conclusions. Cervical recurrences occur predominantly in level II. Relapse in level I is frequent only in oral cavity tumors and relapse in level V is rare. The neck recurrence carries a poor prognosis even among patients who underwent retreatment with curative intent.
