Clinical Significance and Indication for Surgical Treatment of Occult Cervical and Intraglandular Nodal Involvement in Parotid Malignancy

摘要

Purpose: Surgical management, including the extent of surgery, for patients with parotid malignant tumors has been challenging. The aims of the present study were to identify the factors associated with survival, estimate the incidence of occult nodal and intraglandular metastases, and determine the predictive influence on overall and disease-free survival, with consideration of the surgical extent.
