Prognostic significance of the 9th TNM lung cancer staging system in SCLC
This retrospective analysis confirmed a significant difference in prognosis between the N<sub>2a</sub> and N<sub>2b</sub> subgroups in the 9th edition. No statistically significant difference was observed between the M1c1 and M<sub>1c2</sub> subgroups. The present study suggests that the 9th edition of TNM requires further validation using external datasets, and factors such as the number of metastatic lesions in a single organ may also be included in future TNM classification systems.
