Abstract
Oral cancer is one of the universally prevalent cancer type, and squamous cell carcinomas account for more than 90%. Fundamental knowledge such as the epidemiology and etiology of the oral cancer, imaging anatomy of oral cavity, and AJCC/UICC (American Joint Committee of Cancer/International Union Against Cancer) TNM classification is needed for image interpretation. The new concept of depth of invasion in T classification and extra-nodal extension in N classification is added from AJCC/UICC 8th edition. These items will be described earlier in this chapter.
The oral cavity is divided into eight subsites (mucosal lips, oral tongue, upper alveolar ridge, lower alveolar ridge, retromolar trigone, floor of mouth, buccal mucosa, and hard palate). The invasion pattern of oral cavity cancer differs depending on the primary site of involvement. The invasion pattern of oral cancer according to the primary involvement of each subsite is discussed later in this chapter. We also discuss lymph node metastasis, post-treatment imaging results, treatment complications, and recurrence in oral cancer.
