Abstract

PURPOSE

The aim of this study is to evaluate risk factors of neck recurrence in patients with pN1-N2 neck stage, submitted to a modified radical neck dissection with preservation of the internal jugular vein.

MATERIALS AND METHODS

We reviewed the medical records of 72 patients with squamous cell carcinoma of the oral cavity (43 cases) and oropharynx (29 cases). The clinical stage of the neck was N1 in 23 cases and N2a-c in 49.

RESULTS

Neck recurrences occurred in 6 cases at the side in which the internal jugular vein was preserved. Neck recurrence did not have significant correlation with tumor site (P = .391), T stage (P = .999), N stage (P = .203), adjuvant radiotherapy (P = .999), number of positive lymph nodes (P = .180), lymph nodes size (P = .429), and extracapsular spread (P = .400).

CONCLUSIONS

Modified radical neck dissection with internal jugular vein preservation can be performed in selected patients with lymph node metastases, with no significant increase on the risk of neck recurrence.
