Colon cancer staging is an estimate of the amount of penetration of a particular cancer. It is performed for diagnostic and research purposes, and to determine the best method of treatment. The systems for staging colorectal cancers depend on the extent of local invasion, the degree of lymph node involvement and whether there is distant metastasis.

DuBrow and Chusilp Charnsangavej 2020-01-01 · The present study has revealed that existing standard of primary staging colon cancer CT reports used in clinical radiology consistently may omit key information when describing tumours. The practice of using standard template reporting has been reported to increase the included amount of key tumour descriptors when compared to free-text reporting in primary staging rectal cancer [ 14 ]. 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).
