[Immunotherapy advances for lung cancer combined with chronic obstructive pulmonary disease].

Lung cancer is a major public health problem worldwide, with high rates of morbidity and mortality. It often coexists with chronic obstructive pulmonary disease (COPD), the diagnosis and management of which often receives insufficient attention. In particular, the presence of COPD has significant implications for the clinical management of lung cancer patients. This review systematically assesses the influence of COPD on the efficacy of immunotherapy and the occurrence of immune-related adverse events in patients with lung cancer, identifies existing challenges and proposes avenues for future research in this field.
