Abstract: Objective :To evaluate the operative security and long term survival after sleeve lobectomy for lung cancer. Methods : Between October, 1999 to December 2003, 94 patients underwent radical resecton of lung cancer were respectively analyzed, including 11 sleeve lobectomies (group I),17 pneumonectomies (group II)and 66 lobectomies (group IQ).The intubation time, ICU care duration,anastomotic complications and operative mortality between groups were compared to evaluate the operative security for sleeve lobectomy. The survival and recurrence between group I and II were compared to assess its long term efficacy. The X2 or fisher's precision test was used for comparision of rates,test for means, Iaplan-Meier method and Log rank test for suvival analysis. The criteria for the significant difference cx=0.05. Results :Operative mortality was 0,11.8%,3.0%(I,II,IQ)for each group without significant difference. Mean intubation time (days) was 0.5±2.3, 2.0±7.2, 0.6±4.1 respectively(I,IQVSII,P<0.05). Anastomotic complication rate was 3.0%, 0, 5.8% without significant difference. The 1-year and 3-year survival was 45.5% and 32.5% for group I,58.8% and 45.8% for group II .There was no significant difference between groups for the survial, recurrence or metastasis rates. Conclusions :Sleeve lobectomy is a safe, efficacious surgical option for lung cancer, with better operative safety compared to pneumonectomy. Its recurrence, metastasis or long term survival are allcomparable to the cases of lobectomy.
