Clinical Analysis of Chronic Obstructive Pulmonary Disease Complicating Lung Cancer

Wang Yanyu;Liaoning Cancer Hospital;  
Objective the study was designed to analyze the clinical features of chronic obstructive pulmonary disease complicating lung cancer,to distinguish the differences between it and the simple chronic obstructive pulmonary disease(COPD) on clinical features,and to explore more practical and feasible diagnosis and treatment methods.Methods 75 cases of chronic obstructive pulmonary disease complicating lung cancer patients receiving treatment in our hospital from April,2014 to February, 2016 were selected, compared and contrasted with 80 cases of patients with simple chronic obstructive pulmonary disease; all of those patients were randomly divided into observation group and control group.Patients were diagnosed based on chest imaging,pulmonary function tests and histopathology,who were analyzed from multi-aspects such as age,smoking index,clinical manifestations, respiratory disease history,tumor disease history,COPD grade and course;this helped the researchers to understand the dangerous factors causing the chronic obstructive pulmonary disease complicating lung cancer,and to conduct the Logistic multivariate regression analysis.Results Older than 70 years old,smoking index is more than 600 per year,the clinical manifestations of pulmonary function decline,COPD II grade and duration more than 10 years are the main risk factors causing chronic obstructive pulmonary disease complicating lung cancer;among those factors,the duration of more than 10 years leads the highest level of risk(OR=4.084);patients with it needs emphasized prevention and control with advanced and accurate diagnosis method.Conclusion to adopt advanced and accurate diagnosis methods,to detect cancer manifestations in time for patients with COPD,and to conduct early treatment for patients would improve the efficiency of treatment and provide protection for their life and health safety.
