Prospective validation of the Martinez-Gimeno clinicopathologic scoring system (MGSS) for evaluating risk of cervical lymph node metastases of squamous cell carcinoma of the oral cavity.

Background: The prediction of neck metastasis from oral squamous cell carcinoma is an unresolved issue. The Martinez-Gimeno Scoring System (MGSS) is an index designed as a predictive aid that may be implemented after analysis of the tumor resection.

Methods: A double-blind cohort study was designed and carried out in a tertiary hospital.
