Chronic obstructive pulmonary disease in lung cancer – underdiagnosed and undertreated

Short-term effects of inhalative tiotropium/formoterol/budenoside versus tiotropium/formoterol in patients with newly diagnosed chronic obstructive pulmonary disease requiring surgery for lung cancer: a prospective randomized trial

“…In a retrospective review of 102 patients with a new diagnosis of lung cancer, Kobayashi et al reported on untreated COPD in 21 (25%) patients [14]. Similarly, in a study of 50 patients with newly diagnosed lung cancer, 27 (54%) were newly diagnosed with COPD, of which 10 (20%) had moderate-to-severe COPD [6]. COPD is an independent risk factor for morbidity and mortality in patients with lung cancer.…”

“…COPD is largely underdiagnosed and undertreated [4,5]. Thus, a new diagnosis of COPD is often made during the evaluation of patients requiring a surgical intervention for lung cancer [6]. COPD is an independent risk factor and a cause of morbidity and mortality in patients with lung cancer [7].…”
