Factors Influencing Mandibular Invasion, Lymph Node Metastasis and Extracapsular Spread in Squamous Cell Carcinoma of the Oral Cavity

The independent risk factor for extracapsular spread is lymph node size. Lymph node metastasis and nodal size, pattern of invasion, mandibular invasion, and extracapsular spread are independent risk factors affecting overall survival.
