[Treatment of superior lobe central lung cancer with lung replantation].

BACKGROUND

Patients suffering from lung cancer often have poor quality of life after pneumonectomy. It has clinical significances to preserve maximum lobes of the "healthy" lung. The aim of this study is to report the applications of lung replantation in treatment of superior lobe central lung cancer.

METHODS

Three lung cancer cases were included and analysed. The bronchus and margin of lower lung lobe were encroached by cancer. Pulmonary artery was invaded and surrounded by metastatic lymph node. Complete pneumonectomy, antegrade perfusion and retroperfusion with low-potassium dextran (LPD) solution in vitro were performed. The retainable lower pulmonary lobe was selected from the isolated lung and superior pulmonary vein was replaced with inferior pulmonary veins. The bronchus and pulmonary artery were inosculated by turns.

RESULTS

The operative cumulative time ranged from 220 min to 250 min. The isolated time of lobus inferior pulmonary ranged from 120 min to 150 min. The chest tube was pulled out after chest X-ray confirmed the reimplant lung full re-expansion. The patients were followed up for 4 months to 8 months and accomplished adjuvant chemotherapy for 3 or 4 periodicities. The patients had a sound quality of life.

CONCLUSIONS

Lung replantation removing the extensive tumor tissue and retaining the maximum pulmonary normal tissue is an useful method for treatment of lung cancer.
