Clinical characteristics of chronic obstructive pulmonary disease in patients with non-small-cell lung cancer / 中国综合临床

ABSTRACT

Objective To explore the clinical characteristics and perioperative treatment of chronic obstructive pulmonary disease (COPD) in patients with non-small-cell lung cancer (NSCLC) in department of thoracic surgery,and to guide the clinical diagnosis and treatment. Methods From January 2013 to December 2016,patients with newly diagnosed NSCLC treated in the thoracic surgical department of Lanzhou University Second Hospital were reviewed retrospectively. The patients were divided into the COPD group and non-COPD group. The clinical data,including the incidence and clinical characteristics of COPD in non-small-cell lung cancer,pulmonary complications after surgery,COPD diagnosis and perioperative pulmonary rehabilitation were analyzed retrospectively. Results A total of 726 NSCLC patients were reviewed,six hundred and seventy-five cases who took the full lung function test were included in the study,of which 95 cases received bronchial diastolic test,86 cases were accorded with COPD diagnosis and were included in incorporated COPD group,and 589 cases were in the non- incorporated COPD group. The proportion of men (69 cases,80. 2%,χ2 = 24. 032), age ≥65 (51 cases,59. 3%,χ2 = 6. 784),smoking history (55cases,64. 0%,χ2 = 29. 474) and a large number of smokers (43 cases,50. 0%,χ2 = 5. 802) and lung squamous cell carcinoma(47 cases,54. 7%,χ2 = 6. 241) in the incorporated COPD group were higher than those in differences were statistically significant (P<0. 05); the incidence of pulmonary complications after radical resection of lung cancer in the incorporated COPD group was 23. 9% (16/ 67),which was significantly higher than that in the unincorporated COPD group(13. 7% (78/568)) (χ2 = 4. 894,P<0. 05). The incidence of pulmonary complications in the lung rehabilitation group was 13. 5% ( 5/37) , lower than that of the non-lung rehabilitation group ( 36. 7% ( 11/30 ) ) (χ2 = 4. 886, P<0. 05);Among the 86 cases (12. 7%) of incorporated COPD,only 6 cases (8. 9 ‰) were diagnosed with COPD at the time of admission, and 23 cases ( 3. 4%) at discharge. No COPD guidelines were given. Conclusion NSCLC often combined wtith COPD,especially in males,elders (≥65 years old) ,smokers, squamous cell carcinoma patients. At present,the diagnosis and treatment of co-morbidity of COPD is seriously inadequate,which needs to be paid much attention to by the thoracic surgeons,in order to improve the diagnosis and treatment of COPD,and improve the prognosis of the patients with NSCLC and COPD.
