The existing 7th edition American Joint Committee on Cancer (AJCC) tumor-node-metastasis (TNM) staging system is widely used to predict survival for colorectal cancer patients and to guide adjuvant chemotherapy after potentially curative surgery. However, none of these tests has been shown to impact management of the breast cancer patient and their routine use is not recommended. Ongoing prospective studies will further quantify the risk associated with the presence of bone marrow micrometastases, but there are, at present, no data on the outcome of bone marrow micrometastases–negative patients who avoid chemotherapy. • Staging describes the extent or severity of a person’s cancer. A staging system is a standard way to sum up how large a cancer is and how far it has spread. Although the available data are provocative, no studies have demonstrated that patients with detectable CTCs by any method should be treated differently from those who do not have them. T4:site/tumor specific, generally direct extension into adjacent organs/tissues 1. Staging cancers is important to determine the prognosis of a patient and what treatment they might best benefit from. In the eighth edition, mitotic rate is removed as a staging criterion for T1 lesions and the tumor classification is recorded to the nearest 0.1 mm rather and 0.01 mm. Gastric cancer can lead to drop metastases to the large and small bowel, pelvic floor, and ovary. Both stage and tumor grade are important prognostic factors for survival. It is the most commonly used staging system by medical professionals around the world. Knowing the stage of disease helps the doctor plan treatment and estimate the person’s prognosis. 2017 Nov;24(12):3683-3691. doi: 10.1245/s10434-017-6078-x.

The TNM staging system (officially known as the TNM classification system of malignant tumors) is a cancer staging system overseen and published by the Union for International Cancer Control (UICC). In the 2002 TNM staging system, bladder neck invasion was designated as pT4 disease, whereas in the 2010 and 2017 TNM scheme, microscopic bladder neck invasion is assigned as pT3a cancer.1318,1322 In the past, prostate cancer with bladder neck invasion was considered as advanced disease, similar to external sphincter or rectal involvement, based on the concept that tumor invading surrounding structures is more aggressive and warrants higher staging. This staging system is used for most forms of cancer, except brain tumors and hematological malignancies. This is the most widely used system for pleural mesothelioma. TNM stands for Tumor, Nodes, and Metastasis. N0:no regional nodal metastasis 3. Spread also occurs via lymphatics and blood vessels. Ultrasound, CT scans, isotope scans, and MRI imaging means that metastases as small as a few mm—but not micrometastases—can be detected in all organs. Extensive local invasion by gastric cancer is common and most often involves the pancreas, omentum, transverse colon, liver, or spleen; direct contiguous spread into the esophagus or duodenum is also common. The tumor, node, metastases (TNM) system used for mycosis fungoides (MF) and Sézary syndrome (SS) is not appropriate for other primary cutaneous lymphomas. The TNM staging system for all solid tumors was devised by Pierre Denoix between 1943 and 1952, using the size and extension of the primary tumor, its lymphatic involvement, and the presence of metastases to classify the progression of cancer.

TNM was adopted by the American Joint Committee on Cancer (AJCC) and issued their first edition in1977. The other main stages range from I (1) through IV (4). Presence of serum LDH level elevation confers a subdesignation within each M grouping in recognition of its prognostic significance—for example, a patient with CNS metastases without elevated LDH would be classified as M1d (0) versus M1d(1) in a similar patient with LDH above the upper limits of normal at the time of staging. In general, patients who have large tumors and/or positive regional lymph nodes have a higher chance of distant recurrence, and death, than those with small tumors and uninvolved lymph nodes. Early stages had a significant longer recurrence-free survival (86 to 90%) than advanced stages III and IV (55 to 56%). Treatment options are directly influenced by tumor stage. Staging is based on commonly understood knowledge about the way cancer develops and spreads. S-phase fraction, DNA ploidy, and an elevated thymidine labeling index (TLI) are signs of increased proliferation and have been correlated with tumor size, grade, and stage. TNM Staging System Cancer staging systems are used to classify how advanced a cancer is in the body by determining a particular stage, generally 1 through 4. The 7th lung cancer TNM classification and staging system: Review of the changes and implications. T1:site/tumor specific, generally small 5.

The UICC TNM staging system is the common language in which oncology health professionals can communicate on the cancer extent for individual patients as a basis for decision making on treatment management and individual prognosis but can also be used, to inform and evaluate treatment guidelines, national cancer planning and research. The presence or absence of metastases to other organs—the “M” number. You have the key to the code. Metastasis (M): Has the cancer spread to other parts of the body? For many purposes, a single number for each letter is sufficient. In the TNM system, the earliest stage is stage 0 (also called carcinoma in situ, or CIS). Prognosis is dependent both on stage of disease and location within the stomach. With lymphomas, the cancer originates in the lymph nodes, so the TNM system of spreading to regional lymph nodes doesn't apply rather well.
