ABSTRACT
<p><b>BACKGROUND</b>Lung cancer invading left atrium or base of pulmonary vein belongs to locally advanced lung cancer (T4). The prognosis of treatment without surgery is poor. The aim of this study is to explore the feasibility and the value of surgical method in the treatment of this disease.</p><p><b>METHODS</b>From April, 1993 to April, 2005, lobectomy or pneumonectomy combined with extended resection of left atrium were carried out in 46 patients with locally advanced lung cancer. The operations included left low lobectomy in 20 cases, left pneumonectomy in 6 cases, right middle and low lobectomy in 12 cases, right low lobectomy in 3 cases and right pueumonectomy in 5 cases respectively. The base of the pulmonary vein was invaded by the tumor in 34 patients, while left atriums were invaded obviously in 12 patients. Two patients were operated using extracoporeal circulation because of main pulmonary artery and left atrium being invaded. The Kaplan-Meier method (Log rank test) and a COX model were used to analyse the survival and the prognosis.</p><p><b>RESULTS</b>There was no operative mortality in this series, 15 patients had operative complication, including arrhythmia in 13 cases, pneumonia in 8 cases and heart failure in 1 case. The median survival was 35 months. The 1-, 3-, 5-year survival rates were 84.2%, 43.7%, 30.5% respectively. The survival of patients with N0/1 was better than that of patients with N2 disease, the median survival of them were 38 months and 19 months respectively (P=0.002). Using a Cox model analysis, lymph node stage (N0/1 or N2) was independent prognostic factor, while preoperative chemotherapy, sex, age and the pathologic type were not independent prognostic factors.</p><p><b>CONCLUSIONS</b>Surgical treatment for lung cancer invading the left atrium or the base of pulmonary vein is feasible, especially for N0 patients.</p>
