TNM 2010

TNM classification for lung cancer.

The international tumor-node-metastasis (TNM) staging system is the "international language" in cancer diagnosis and treatment. Six revisions of the TNM staging system for lung cancer have been repeated over the past 35 years after the beginning of UICC-TNM classification in 1968. The 1997 revision for lung cancer has undergone an extensive correction for many deficiencies of the old staging sy...

TNM residual tumor classification revisited.

BACKGROUND For cancer patients, prognosis is strongly influenced by the completeness of tumor removal at the time of cancer-directed surgery or disease remission after nonsurgical treatment with curative intent. These parameters define the relative success of definitive treatment and can be codified by an additional subclassification within the TNM system, the residual tumor (R) classification....

TNM-O: A Modular Ontological Approach for the Representation of Tumour Entities across TNM Versions

The TNM classification (Tumour-Node-Metastasis) is the most important coding scheme used to stage tumours based on size or location. Its coding rules often change with different TNM versions, such that the same tumour may be represented by different codes in different TNM versions. We present an ontologybased modular architecture for the management of the TNM coding system. Separate OWL files r...

An Ontology for TNM Clinical Stage Inference

TNM is a classification system for assessment of progression stage of malignant tumors. The physician, upon patient examination, classifies a tumor using three variables: T, N and M. Definitions of values for T, N and M depend on the tumor topography (or body part), specified as ICD-O codes. These values are then used to infer the Clinical Stage (CS) and reflect the disease progression, which c...
