Neoplasia: TNM staging

Contributor(s): Laura Garrett, Gerry A Polton

Introduction

  • Anatomical classification giving an objective description of the extent of the neoplasm.
  • Extent of primary tumor (T) and the presence, absence or likelihood of metastatic disease (N, M) are of great importance in determining the feasibility of therapy and the overall prognosis.
  • There is a difference between clinical stage and true pathological stage of the disease because it is often impossible to detect microscopic tumor extensions or deposits.
  • Location of the tumor and histological type and grade are also of prognostic significance.
