Intraparotid Lymph Node Metastasis and Survival in Parotid Malignancies.

Objective: This study aimed to determine the incidence of intraparotid lymph node metastasis in parotid malignancies and its association with overall survival. Methods: This study retrospectively reviewed the charts and histopathological findings of 43 patients with parotid malignancies who underwent surgery between 2008 and 2015. Epidemiological and pathological data were recorded. Overall survival was calculated, and univariate and multivariate analyses were used to determine the role of metastasis intraparotid lymph node as a prognostic factor. Results: The incidence of metastasis intraparotid lymph node was 46.5%. Advanced-stage and high-grade tumors were associated with a higher metastasis intraparotid lymph node risk. Survival was significantly decreased in the metastasis intraparotid lymph node group, overall cohort (hazard ratio, 7.52), and advanced-stage group (hazard ratio, 4.62). No significant prognostic factor was revealed by multivariable analysis. Conclusion: Metastasis intraparotid lymph node is common and may negatively affect survival in parotid malignancies.
