[Surgical Treatment of Lung Cancer: How Has the Introduction of the 8th Edition of the TNM Classification Affected Guideline-Based Therapy?]

CONCLUSION: The 8th edition of the TNM-classification affords a higher level of differentiation. In this study, the new TNM classification led to a shift in the distribution, with a tendency to increase the tumour stage. This is mainly caused by changes in the T-descriptor and stage grouping. As a result, fewer patients in stage I - IIIA should have surgery according to the latest S3 guidelines. A significantly higher two-year survival rate was detected in stage IVA (M1a and M1b) compared to IVB and justifies the new differentiation due to the metastatic pattern.
