INTRODUCTION: Occult regional metastases in supraglottic cancer NO are the object of classical controversies. The aim of our study is to provide our experience in order to determine how neck treatment affects on regional recurrence of NO supraglottic cancer.
METHODS: A retrospective study of 246 patients with NO supraglottic cancer treated in our service between 1977 to 1999 is presented.
RESULTS: 11.4% of patients did not have any cervical treatment, with a 23% of neck recurrence amongst the evolution. 66.7% of patients were treated with a modified radical neck dissection, 24% of these presented occult metastases in the histopathological study. Global regional recurrence was 2.9% in early stages (T1/T2) and 13.1% in advanced stages (T3/T4). In pN+ patients, 85% underwent postoperative radiotherapy, with a regional recurrence of 8.8%. Postoperative clinical control without any other treatment in pN0 patients showed a neck recurrence of 6.1%. We performed a unilateral neck dissection in those patients with clear-lateral tumours. In these cases the clinical control of the contralateral neck gave a 5.5% recurrencies on that side. Patients treated with elective primary radiotherapy suffered a 5.5% of regional recurrence.
DISCUSSION/CONCLUSIONS: Neck treatment of the NO supraglottic cancer is recommended. We treat neck in the same way of primary tumour (surgery or radiotherapy) with good control of regional recurrencies, less than 10%. In case of a negative pathological study of the neck careful, watching is the elective attitude. In the positive pathological study of the neck (pN+), radiotherapy is the elective treatment in those with three or more affected nodes or capsular breakdown in any of them.
