Proposed Scales for Intraoperative Quantification of Surgical Complexity in Early NSCLC After Neoadjuvant Immunotherapy

Grade	Characteristics
Nonmalignant lymphadenopathy
0	Lymphadenopathy <1 cm
1	Lymphadenopathy 1 to <2 cm
2	Lymphadenopathy 2 to <3 cm
3	Lymphadenopathy ≥3 cm
Peripheral (pleural) fibrosis
1	Mild fibrosis (no substantial impact on conduct of surgical resection)
2	Moderate fibrosis (requires increased effort and dissection during resection but otherwise does not severely impact the conduct of the surgery)
3	Severe fibrosis (substantially impacts the conduct of the operation by increasing the duration of or blood loss during the surgery, or requires converting minimally invasive to open surgery)
4	Severe fibrosis resulting in unresectability
Central vs. peripheral lung cancer
1	Central (inner two-thirds of lung)
2	Peripheral (outer two-thirds of lung)
Perihilar/lobar or mediastinal adhesions
1	Mild fibrosis (no substantial impact on conduct of surgical resection)
2	Moderate fibrosis (requires increased effort and dissection during resection but otherwise does not severely impact the conduct of the surgery)
3	Severe fibrosis (substantially impacts the conduct of the operation by increasing the duration of or blood loss during the surgery, or requires converting minimally invasive to open surgery)
4	Severe fibrosis resulting in unresectability
