Update on Lung Cancer Staging (TNM 9th edition): What the Thoracic Radiologist Needs to Know

Introdução e objetivo(s)

The TNM classification system guides lung cancer staging and treatment. The 9th edition (TNM-9) introduces refinements to nodal and metastatic classifications, improving prognostic accuracy. This review highlights key updates for radiologists and residents.

Método(s)

This review outlines TNM-9’s development by IASLC, emphasizing multimodality imaging (CT, PET-CT) and comparing TNM-8 and TNM-9’s impact on staging and prognosis.

Discussão

N2 Subclassification (N2a, N2b): New TN subsets, like T1N2a (stage IIB), refine prognosis.

M1c Subclassification (M1c1, M1c2): Further stratifies prognosis within stage IVB.

Imaging Considerations: PET-CT enhances precise staging.

Illustrative Cases: Practical comparisons highlight TNM-9’s clinical relevance.

Conclusões

TNM-9 enhances lung cancer staging, refining prognosis and treatment strategies. Precise imaging remains vital. Future developments, like liquid biopsy and AI, may further improve staging and management.
