Squamous cell carcinoma of the oral cavity: A clinicopathologic scoring system for evaluating risk of cervical lymph node metastasis

A series of 126 cases of squamous cell carcinoma of the oral cavity with neck dissection was studied. Several clinicohistologic parameters and statistical correlation with lymph node metastasis were evaluated. Statistical association with metastasis was found in the following factors: microvascular invasion (P < 6 x 10(-7)), grade of differentiation (P < .0001), T category (P = .003), tumor thickness (P = .005), inflammatory infiltration (P =...
