Approximately 52,980 Americans are expected to die of large bowel cancer each year. metastasis (TNM) staging system for colon cancer and compare it with the Dukes’ system. Methods: A hierarchical clustering algorithm generated tree-structured dendrograms that stratified patients according to survival only. The dendrograms were constructed with the same prognostic variables used for the TNM. Cancer of the colon is a highly treatable and often curable disease when localized to the bowel. Surgery is the primary form of treatment and results in cure in approximately 50% of the patients.

It is therefore important that the edition of TNM being used to stage patients is recorded. Notes **Note 1:** High grade dysplasia and severe dysplasia of the colon are generally not reportable in cancer registries. * Assign pTis if your registry collects these tumors **Note 2:** In situ includes cancer cells confined within the glandular basement membrane (intraepithelial); localized includes confined to lamina propria (intramucosal), the muscular mucosa, and muscularis propria.

The classification of cancer by anatomic disease extent, i.e. stage, is the major determinant of appropriate treatment and prognosis. La letra “M” en el sistema TNM describe el cáncer que se ha diseminado a otras partes del cuerpo, como el hígado o los pulmones. Esto se denomina metástasis a distancia. M0 (M más cero): la enfermedad no se ha diseminado a partes distantes del cuerpo. M1a: el cáncer se diseminó a 1 parte del cuerpo más allá del colon o del recto.
