Abstract
BACKGROUND: Postoperative cardiopulmonary complications might be fatal for patients with lung cancer after surgery. The aim of this study was to identify the risk factors of postoperative cardiopulmonary complications in lung cancer patients and get a fitting formula for predicting incidences of cardiopulmonary complications. METHODS: We conducted a retrospective analysis of 653 patients with a diagnosis of lung cancer who underwent a surgery in the Tianjin Medical University Cancer Institute and Hospital (Tianjin, China) from January to December 2014. All patients received lung cancer surgeries. Clinical data was collected for the analysis of the influence factors of cardiopulmonary complication after lung cancer surgeries. The medical statistical analysis program R was used to calculate cardiopulmonary complication probability of classification of quantitative results. RESULTS: Our work showed that ages, lymphocyte count, smoking history, chronic bronchitis history, operation mode and extubation time were significantly associated with lung infection both in univariate and multivariate survival analysis. And ages, smoking history, arrhythmia of electrocardiogram and operation mode were significantly associated with postoperative arrhythmia both in univariate and multivariate survival analysis. Multiple linear regressions were generated with risk factors by program R software. Finally, we got a fitting formula for predicting cardiopulmonary complications. Risk score for each patient could be obtained by this formula. CONCLUSIONS: The incidences of pulmonary infection and arrhythmia were high for patients who underwent lung cancer surgery. It is important to discriminate risk factors for each patient for reducing the risk of heart and lung complications. Preoperative quantitative evaluation of cardiopulmonary complication after operation is beneficial to the risk control.
