Objective To compare the incidence of cardiopulmonary complications between treatment of video assisted thoracoscopic operation and traditional thoracotomy operation in elderly patients with non-small cell lung cancer.Methods 122 cases of elderly patients with non small cell lung cancer were treated in our hospital from Mar 2010 to Jun 2014,and randomly divided into observation group (therapeutic lobectomy by video assisted thoracoscopic operation) and control group (therapeutic lobectomy by traditional thoracotomy operation) (n=61,each).The postoperative cardiopulmonary complications and relevant indexes of cardiopulmonary function were analyzed and compared between the two groups.Results Before operation,there was no significant difference in the relevant indexes of cardiopulmonary function between the two groups (P＞0.05).After operation,the forced expiratory volume in one second (FEV1) and maximal ventilatory volume (MMV) were higher and the heart rate was lower in observation group than in control group (t=3.682,2.243,5.677,all P＜0.05).The incidence of cardiopulmonary complication was lower in observation group than in control group (13.1％ vs.27.9％,x2 =4.075,P=0.044).Conclusions Video assisted thoracoscopic operation is better for the recovery of cardiopulmonary function,and can reduce cardiopulmonary complication in elderly patients with non-small cell lung cancer.

Objective To analyze prognostic factors of surgical treatment for elderly patients with non-small cell lung cancer,in order to provide a theoretic basis for improving the prognosis of patients with non-small cell lung cancer.Methods Clinical data of 145 elderly patients with non-small cell lung cancer who had received surgical treatment at our hospital from January 2012 to September 2012 were retrospectively analyzed.The survival rates of patients were investigated.Results The median survival time was 31.5 months,and 1-year,2-year and 3-year survival rates were 61.4％,45.5％ and 40％,respectively.Single factor analysis showed that lesion size,number of metastatic lymph nodes,clinical stage,pathological type and radiotherapy were among the factors affecting prognosis.Multiple COX regression analysis showed that a lesion size ＞3cm,number of lymph nodes with metastasis ＞ 2 and pathological type were independent risk factors for patient prognosis,and radiotherapy was a protective factor for prognosis.Conclusions Surgical treatment has good curative effects on non-small cell lung cancer in elderly patients.Lesion size,number of lymph nodes with metastasis,pathological type and radiotherapy are important factors affecting prognosis,and can be used for prognosis assessment.
