developed a nomogram from a 164-subject dataset; chronic obstructive pulmonary disease (COPD) diagnosis, PD-L1 expression and interleukin 8 (IL-8) levels were included as final predictors for incidence of ICI pneumonitis in non-small cell lung cancer (NSCLC) patients (10). The gene discussed is CXCL8; the disease is non-small cell lung carcinoma.
