TNM Staging of oral cancer. The current AJCC/UICC TNM staging (8th edition, 2017) of OSCC has included significant modifications through the incorporation of depth of invasion in the T stage and extracapsular spread/extranodal extension in the N stage. The American Joint Committee on Cancer (AJCC) tumor/node/metastasis (TNM) classifications for oral cavity and laryngeal cancers are provided below, along with histologic grades and anatomic stages. 2017 Mar 1;67(2):122-37.

While the seventh edition TNM staging of OPC adequately reflects the behavior of those cancers typically associated with tobacco and alcohol abuse (not caused by HR‐HPV), it does not properly describe HR‐HPV disease with respect to prognosis or behavior. It is described as follows-T STAGING. N indicates whether or not the cancer has reached nearby lymph nodes. 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. This is done for several reasons, the most important of which is providing a universally understood definition of a particular cancers progress. The first step in staging is to find the value for each part of the TNM system. All cancerous tumors are staged by determining the tumor size (T), the lymph node status (N) and the presence of metastasis (M). The cancer stage helps you and your doctor to develop a treatment plan. For oral cancer there are 5 stages – stage 0 followed by stages 1 to 4. CA: a cancer journal for clinicians.

Pathologic staging combines the results of both the clinical staging (physical exam, imaging test) with surgical results. T stands for tumour size. Generally, the higher the stage number, the more the cancer has spread. Prognosis of oral cancer is predicted by using staging and grading.

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). No spread to nearby lymph nodes or distant body parts. On the other hand, the World Health Organization (WHO) classification (4th edition, 2017) still endorses a simple, differentiation-based histopathologic grading system of OSCC (despite its low prognostic value) and ignores factors such as tumor growth pattern and dissociation, stromal reactions (desmoplasia, local immune response), and tumor-stroma ratio. It has gained wide international acceptance for many solid tumor cancers, but is not applicable to leukaemia and tumors of the central nervous system. No cancer cells are present in deeper layers of tissue, nearby structures, lymph nodes or distant sites (carcinoma in situ). Staging and grading of OSCC are established prerequisites for management, as they influence risk stratification and are the first step toward personalized treatment. This system defines cancers by Roman numbers 0 through IV. Staging and grading form cornerstone during cancer management.

Cancer staging can be divided into a clinical stage and a pathologic stage. STAGING T M N 3. The TNM system for oral cancer. Doctors often establish a preliminary disease stage based on physical exam as well as findings on imaging that help to identify the spread of disease. After it has been determined that an actual cancer exists, the degree to which the cancer has developed is determined. Head and neck cancers—major changes in the American Joint Committee on cancer eighth edition cancer staging manual.

This has been adopted in part by the 8th edition of the Union for International Cancer Control (UICC) TNM 8 classification of malignant tumours for oral squamous cell carcinoma (SCC). Oral cancer stages are based on the results of physical exams, biopsies, and imaging tests.

The revised staging system was superior at stratifying patients according to the T classification for both DSS (p = .016) and OS (p < .001). eCancer and UICC jointly produced a set of 7 modules on TNM staging for the purpose of educating and informing the global cancer community on the globally accepted classification of malignant tumours.. This is a simplified description of the T stage. Each TNM category, with its assigned X or numerical value from 0 to 4, falls into one of these stages. Lymph nodes in other parts of the body are called distant lymph nodes. Recent research proposed new grading assessing differentiation and dissociation. 1. TNM stands for Tumour, Node, Metastasis. Dr. Vibhuti Kaul BDS (IGGDC, Jammu) MDS Oral Medicine and Radiology (GDC, Srinagar) 2. Pathologic Staging can only be determined from individual patients who have had surgery to remove a tumor or explore the extent of the cancer.

It is described as follows-T STAGING. Oral cavity carcinoma staging refers to TNM staging of carcinomas involving the oral cavity. This classification is important for treatment planning, estimating risk of recurrence, and assessment of overall survival. TNM Staging System for Papillary Thyroid Cancer (8th Edition): From the Perspective of Genomic Analysis. Conclusion: Tumor thickness is an important prognostic indicator in early oral SCC and should be incorporated in the TNM classification system. The TNM Classification of Malignant Tumors (TNM) is a globally recognised standard for classifying the extent of spread of cancer. Tumour describes the size of the tumour. N (node): This indicates whether the cancer is in the lymph nodes. The updated AJCC/ TNM staging system (8th edition) for oral tongue cancer. Table 1. No spread to nearby lymph nodes or distant body parts. Figure 1. Most hospitals and medical centers use the TNM system as their main method for cancer reporting. Lymph nodes near where the cancer started are called regional lymph nodes. All cancerous tumors are staged by determining the tumor size (T), the lymph node status (N) and the presence of metastasis (M). Transl Cancer Res 2019;8(Suppl 2):S164-S166. T4is split into 2 stages, T4a and T4b: 1. T2means the tumour has grown into the muscle layer of the bowel wall. This staging system is used for most forms of cancer, except brain tumors and hematological malignancies. The staging system most often used for oral cavity or oropharyngeal cancers is the American Joint Committee on Cancer (AJCC) TNM system, which is based on 3 key pieces of information: 1. In the TNM (Tumor, Node, Metastasis) system, clinical stage and pathologic stage are denoted by a small "c" or "p" before the stage (e.g., cT3N1M0 or pT2N0). The chances of successful treatment depend on how large the cancer has grown and whether it has already spread to other sites in the body. These revised editions of TNM classification are not used in every country; TNM5 is still predominantly used in Western countries, including the United Kingdom, the Netherlands, Belgium, and Denmark, 4 whereas in Japan, none of the newly revised TNM criteria regarding ND were adopted in the national cancer staging manual edited by the Japanese Society for Cancer of the Colon and Rectum … There are different staging systems doctors can use for mouth cancer.

It has gained wide international acceptance for many solid tumor cancers, but is not applicable to leukaemia and tumors of the central nervous system. The TNM stages closely match the FIGO stages, which makes it fairly easy to convert stages between these 2 systems. Staging systems other than the TNM system are often used for Hodgkin and non-Hodgkin lymphomas, as well as for some other cancers. 3. There are many lymph nodes in the head and neck area. Generally, the higher the stage number, the more the cancer has spread. This classification is important for treatment planning, estimating risk of recurrence, and assessment of overall survival. Sometimes also described as the AJCC system. Module 6: UICC TNM Lip and Oral Cavity Cancer Classification; Module 7: UICC TNM Lung Cancer Classification; In French: TNM e-Modules en français. A head and neck surgeon performed clinical TNM staging. The tumor-node-metastasis (TNM) staging system was first reported by Pierre Denoix in the 1940s.1 The International Union Against Cancer (UICC) eventually adapted the system and compiled the first edition of the TNM staging system in 1968 for 23 body sites. T3means the tumour has grown into the outer lining of the bowel wall but has not grown through it. © 2020 The Authors.
