[Latero-cervical metastasis of N0 laryngeal cancer].
The authors report a pathological study of functional neck dissection performed on 145 N0 laryngeal carcinoma patients from 1982 to 1988. The incidence of occult latero-cervical metastases in N0 was evaluated in relation to site and extension of the primitive tumor. A total of 108 supraglottic, 25 glottic and 12 transglottic tumors were observed. Among the cases treated the incidence of occult metastases was 28.3% while capsular rupture accounted for 3.4%. Diagnostic error, calculated on the number of neck dissections, was 20.2%. A greater incidence of occult metastases was found in supraglottic tumors (29.6%) than in either glottic (24%) or transglottic (25%) tumors. Furthermore, incidence of occult metastases proved proportional to the extension of the primitive tumor. There was a single metastases in 35 cases while only 6 cases proved multiple. Some final considerations are given on the importance of performing precautionary functional neck dissection in N0 laryngeal cancer.
