BACKGROUND: In head and neck cancer, the best prophylactic treatment for the N0 neck is a subject of debate. Some authors propose lateral selective lymph node dissection (levels II-IV) on the basis of the probability of finding occult metastases in those lymph nodes. A more extensive procedure including Vth level is considered unnecessary because of the low incidence of metastases in the posterior triangle. METHODS: We retrospectively evaluated 346 N0 patients affected by laryngeal carcinoma and consecutively treated at the Department of Otorhinolaryngology of the Ospedale di Circolo, Varese, Italy. The patients underwent elective selective neck dissection (levels II-V) for a total of 602 dissected heminecks. RESULT: Seventy heminecks (11.6%) were pN+, and in 10 of 70 cases (14.3%) level V was involved; in 5 of 10 metastases were isolated. CONCLUSION: Our retrospective study confirms the probabilistic criteria of the incidence of occult metastasis by level in laryngeal cancer. On the basis of our data Vth level nodes, although very rarely, 10 of 604 (1.6%), are involved with laryngeal cancer. Our approach to routinely dissect Vth level nodes is discussed

Abstract

BACKGROUND: In head and neck cancer, the best prophylactic treatment for the N0 neck is a subject of debate. Some authors propose lateral selective lymph node dissection (levels II-IV) on the basis of the probability of finding occult metastases in those lymph nodes. A more extensive procedure including Vth level is considered unnecessary because of the low incidence of metastases in the posterior triangle. METHODS: We retrospectively evaluated 346 N0 patients affected by laryngeal carcinoma and consecutively treated at the Department of Otorhinolaryngology of the Ospedale di Circolo, Varese, Italy. The patients underwent elective selective neck dissection (levels II-V) for a total of 602 dissected heminecks. RESULT: Seventy heminecks (11.6%) were pN+, and in 10 of 70 cases (14.3%) level V was involved; in 5 of 10 metastases were isolated. CONCLUSION: Our retrospective study confirms the probabilistic criteria of the incidence of occult metastasis by level in laryngeal cancer. On the basis of our data Vth level nodes, although very rarely, 10 of 604 (1.6%), are involved with laryngeal cancer. Our approach to routinely dissect Vth level nodes is discussed
