Resumo
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 can be 0 (no malignant tumor), IS (in situ), I, II, III, or IV. The
rules for inference are different for each topography and may depend on other
factors such as age. With the objective of evaluating missing CS information
on A. C. Camargo Cancer Center databases, we developed an open ontology to
represent TNM concepts and rules for CS inference. It was designed to be easily
expansible and fast to compute.
