Survival impact of pN2a and pN2b nodal status in stage IIB-IIIB non-small cell lung cancer under the 9th TNM classification

Puntos clave

• This analysis aims to determine the impact of pN2a and pN2b statuses on survival outcomes in patients with stage IIB-IIIB non-small cell lung cancer.
• Used the 9th TNM classification for staging
• Analyzed survival outcomes based on pN2a and pN2b nodal status
• Focused on surgically treated stage IIB-IIIB non-small cell lung cancer patients
• Identified significant differences in survival rates between pN2a and pN2b groups
• Showed that pN2 status is a key survival determinant in this lung cancer stage
