Validation and Comparison of the 7th Edition of the American Joint Committee on Cancer Staging System and Other Prognostic Models to Predict Relapse-Free Survival in Asian Patients with Parotid Cancer

摘要

Purpose: Parotid cancer is a rare malignancy characterized by a heterogeneous histologic subtype and distinct biologic behavior. The present study aimed to externally validate and compare the performances of the American Joint Committee on Cancer (AJCC) staging system (7th Edition), Carrillo score, and Vander Poorten score in the prediction of tumor relapse probability in a large cohort of Asian parotid cancer patients.
