한 줄 요약

Stage II-III NSCLC 100명 real-world cohort에서 neoadjuvant chemoimmunotherapy 후 18%가 planned surgery로 진행하지 못했으며, surgical attrition은 oncologic nonresponse보다 physiologic reserve와 airway/anatomic constraint에 더 크게 좌우되었다.

2. 핵심 기여

  1. Resectable stage II-III NSCLC에서 neoadjuvant chemoimmunotherapy 이후 real-world surgical attrition rate를 18%로 제시했다.
  2. Clinical downstaging이 있어도 planned trimodality pathway 완료가 보장되지 않음을 보였다.
  3. Non-surgical pathways를 close observation without treatment, definitive chemoradiotherapy/radiotherapy, palliative chemotherapy로 나누어 설명했다.
  4. Attrition의 baseline functional predictors로 older age와 low DLCO를 제시했다.
  5. Attrition의 baseline radiologic predictors로 tumor cavitation과 main bronchus abutment를 제시했다.
  6. Surgical completion이 non-surgical management보다 더 좋은 EFS와 관련됨을 보였다.
