Colon cancer is staged by considering three pieces of information: Tumor (T): Provides information about the size of the tumor and how far it has grown into the walls of the colon or nearby organs. The TNM Classification of Malignant Tumors (TNM) is a globally recognised standard for classifying the extent of spread of cancer.It is a classification system of the anatomical extent of tumor cancers. This tool is based on a database of 1,320 patients with nonmetastatic colon cancer treated at Memorial Sloan Kettering Cancer Center. It provides a more accurate picture of the five- or ten-year risk of recurrence than older assessment tools, such as the staging system of the American Joint Committee on Cancer.

Definition / general. Adenocarcinoma, high grade neuroendocrine carcinoma and squamous carcinoma of the colon and rectum are covered by this staging system. Not covered by this staging system are appendiceal carcinoma, anal carcinoma and well differentiated neuroendocrine tumor (carcinoid) Se hela listan på cancer.net The TNM staging system anatomically classifies malignancies based on the extent of the primary tumour, regional lymph node involvement, and distant metastases. Staging helps physicians decide eligibility for clinical trials, define a patient's prognosis, and determine best treatment options. 2012-03-19 · Histologic components of the TNM classification system have been repeatedly revised since the fifth edition (TNM5).

Staging Dukes (Astler-Coller modification) stage A: confined to mucosa; stage B: through muscularis propria; stage C: local lymph node involvement; stage D: distant metastases; TNM staging Primary tumor staging (T) What is the TNM cancer staging system? The TNM Classification of Malignant Tumors (TNM) is a globally recognised standard for classifying the extent of spread of cancer. The classification of cancer by anatomic disease extent, i.e. stage, is the major determinant of appropriate treatment and prognosis.
