The dynamics of lung cancer staging: Key features of TNM 8th edition
S taging cancers is an essential component of oncology practice. TNM staging system provides a common language to
communicate on the disease extent of an individual patient. It groups patients with similar levels of disease and similar
outcomes together. It is crucial in decision making on management of cancers and predicting prognosis. With advances in
treatment and development of new drugs and strategies, the outcomes and survival statistics change over time. As such, there
is a need for reviewing the staging system every few years. TNM 8th edition is currently in practice and it has some big changes
in staging of lung cancer. The importance of tumor size is highlighted in the new staging system and the T stage descriptor
changes with every cm increase in tumor size. Nodal stage has largely remained unchanged but N descriptors have been
proposed for future validation. There is no change in M1a, as a departure from the past oligometastases has been recognized
as a separate category. Single metastasis in a single organ is M1b while multiple metastases in a single or multiple organ is now
M1c. The purpose of this lecture is to look at the rationale behind the changes in staging of lung cancers, getting familiar with
the new staging system and the optimal evaluating tools to accurately stage lung cancers.
