Chronic obstructive pulmonary disease (
COPD) is a common respiratory
disease, and
lung cancer is a common
comorbidity and one of the main
causes of death in
COPD. The coexistence of the two
diseases is related to poor
survival rate. Clinically, it has been found that
COPD has a high
comorbidity rate with
lung cancer,
belonging to a homologous
disease with common
risk factors and pathogenesis.
COPD can be derived from the
soil where
lung cancer occurs. At present, there is much
understanding of the
association between
COPD and the
risk of
lung cancer in clinical practice, but there is no
consensus on the management of
patients with
COPD combined with
lung cancer. There is insufficient
diagnosis and
treatment of
COPD, which
affects the clinical outcomes of such
patients. Therefore, this article reviews the epidemiological status, common
risk factors, related pathogenesis, and management of
COPD combined with
lung cancer in recent years, in order to provide more theoretical basis and
understanding for clinical
research and
treatment.
