INTRODUCTION. Carcinoma of the colon or rectum (colorectal cancer [CRC]) is a common and lethal disease. Approximately 149,500 new cases are diagnosed each year in the United States, of which 104,270 are colon cancers and the remainder are rectal cancers [ 1 ]. Annually, approximately 52,980 Americans die of CRC, accounting for approximately 9

The impact of this new classification on pathology reporting practices has yet to be evaluated. Methods and results No, TNM is a dual system with a (pre-treatment) clinical classification (cTNM or TNM) and a (post-surgical histopathological) pathological classification (pTNM). Both classifications are retained unaltered in the patient's record.

2020-03-23 · TNM Classification for Prostate Cancer The clinical staging of prostate cancer was devised from the American Joint Committee on Cancer (AJCC) tumor, node, metastasis (TNM) system. Risk stratification is based on the clinical stage as well as the following pretreatment parameters: The 8th edition of the TNM classification for non-small lung cancer is shown in the table. Conform previous editions there are three components that describe the anatomic extent of the tumor: T for the extent of the primary tumor, N for lymph node involvement, and M for metastatic disease. Colorectal carcinoma staging can be performed using two systems.
