CLASSIFICATION OF CARCINOMA Carcinoma, like all Neoplasia , is classified by its histopathological appearance. Adenocarcinoma and Squamous Cell Carcinoma , two common descriptive terms for tumours, reflect the fact that these cells may have glandular or squamous cell appearances respectively. Severely anaplastic tumours might be so undifferentiated that they do not have a distinct histological appearance ( Undifferentiated Carcinoma ). Sometimes a tumour is referred to by the presumptive organ of the primary (eg Carcinoma Of The Prostate ) or the putative cell of origin ( Hepatocellular Carcinoma , Renal Cell Carcinoma ).

STAGING The staging of cancers is the extent of spread of the neoplasm. Grading is the system used to record the tumours degree of differentiation from the parent tissue. A high grade shows little differentiation and the prognosis is therefore poor. Carcinomas, like all cancers, are staged according to the extent of disease. The UICC/AJCC TNM system is often used, however for some common tumours, classic staging methods (such as the Dukes classification for colon cancer) are still used. SEE ALSO |
