C140 Pharynx, NOS C142 Waldeyer ring C148 Overlapping lesion of lip, oral cavity, and pharynx **Note 1:** This schema is based on the UICC chapter *Malignant Melanoma of Upper Aerodigestive Tract,* pages 51-53. TNM Classification for Oral Cavity and Laryngeal Cancers The American Joint Committee on Cancer (AJCC) tumor/node/metastasis (TNM) classifications for … Stages of oral cancer. 2. It is a classification system of the anatomical extent of tumor cancers. OSCC has a relatively low survival rate and the incidence of the disease is increasing in some geographic areas. The TNM system for oral cancer. It is described as follows-T STAGING. This is done for several reasons, the most important of which is providing a universally understood definition of a particular cancers progress. The stage and treatment of oral cancer are defined according to the TNM system. The TNM staging system is one of these.

This classification is important for treatment planning, estimating risk of recurrence, and assessment of overall survival. This is a simplified description of the T stage. The anatomy of the oral cavity and the oropharynx (used with permission from artist, Lauren Visserman). This classification is important for treatment planning, estimating risk of recurrence, and assessment of overall survival. These parameters are then combined to give the TNM … Interactive Search is another great feature that proves very helpful in staging cancer disease by tapping on absence or presence of related symptoms that in turn derives staging values.

T: Primary Tumor Tis = Preinvasive tumor (in situ) T0 = No evidence of tumor T1 = Tumor < 2 cm diameter T2 = Tumor 2-4 cm diameter T3 = Tumor 3 cm diameter subclassification of a (no bone invasion) or b (bone invasion) can be added. The TNM system of cancer staging reflects the extent of tumor growth in the whole body and is based on assessment of the size of the primary tumor (T), involvement of locoregional lymph nodes (N), and distant metastases (M). TNM staging is the staging system used for oral cavity cancer.
