Fig. 1From: Down-regulated HHLA2 enhances neoadjuvant immunotherapy efficacy in patients with non-small cell lung cancer (NSCLC) with chronic obstructive pulmonary disease (COPD)NSCLC with COPD patients obtained a higher MPR rate to neoadjuvant immunotherapy. (A) The efficacy to neoadjuvant immunotherapy in NSCLC patients with different COPD status, age, smoking history, gender, clinical stage, PD-L1 expression, treatment cycles, and pathology were compared. (B) Representative pictures of HE staining of patients received neoadjuvant immunotherapy. Left: NSCLC with COPD; Right: NSCLC without COPD. (C) Statistical chart of HE staining in NSCLC with COPD versus NSCLC without COPD patients received neoadjuvant immunotherapy.
