    Abstract:
    OBJECTIVE: To assess the oncological efficacy of selective neck dissection (SND) in patients with T3-4 N0 laryngeal squamous carcinoma. SUBJECTS AND METHODS: A total of 327 patients underwent 654 neck dissections; each side of the neck was individually evaluated. RESULTS: Three percent of patients who had SND developed regional recurrence (RR) in comparison with 11.7 percent of patients who underwent modified radical neck dissection (MRND) (P=0.005). Only 3 (0.9%) patients developed RR outside the field of SND. The presence of extracapsular extension (P=0.002) in node-positive (pN+) group and of microvascular invasion (P=0.007), together with the type of neck dissection (ND) (P=0.0003) in node-negative (pN0) group had statistical impact on RR. The development of RR significantly affected disease-specific survival (P=0.0001). Equivalent rates of RR were found in pN+ (2.6%) or pN0 (3.2%) patients treated with SND (P=0.98) as well as in pN+ patients who underwent SND (2.6%) or MRND (4.7%) (P=0.85). CONCLUSION: This study confirmed the adequacy of SND as a satisfactory staging and therapeutic procedure, and suggests its use in the treatment of limited node-positive (N+) neck.
