Completion pneumonectomy in cancer patients: experience with 55 cases

Objective: Analysis of a single institution experience with completion pneumonectomy. Methods: From 1989 to 2002, 55 consecutive cancer patients received completion pneumonectomy (mean age 62 years; 25-79). Indications were bronchogenic carcinoma in 38 patients (4 first cancers, 8 recurrent cancers, 26 second cancers), lung metastases in three (one each from breast cancer, colorectal neoplasm and lung cancer), lung sarcoma in one, and miscellaneous non-malignant conditions in 13 patients having been surgically treated for a non-small cell lung cancer previously (bronchopleural fistula in 4, radionecrosis in 3, aspergilloma in 2, pachypleura in 1, massive hemoptysis in I and pneumonia in 2). Before completion pneumonectomy, 50 patients had had a lobectomy, three a bilobectomy, and two lesser resections. The mean interval between the two procedures was 51 months for the whole group (1 -469), 60 months for lung cancer (12-469), 43 months for pulmonary metastases (21-59) and 29 months for non-malignant disorders (I - 126). Results: There were 35 right (64%) and 20 left (36%) resections. The surgical approaches were a posterolateral thoracotomy in 50 cases (91%) and a lateral thoracotomy in five cases (9%). Intrapericardial route was used in 49 patients (89%). Five patients had an extended resection (2 chest wall, 1 diaphragm, I subclavian artery and 1 superior vena cava). Operative mortality was 16.4% (n = 9): 11.9% for malignant disease (n = 5) and 30.8% for benign disease (n = 4). Operative mortality was 20% for right completion pneumonectomies (n = 7) and 10% for left-sided procedures (n = 2). Twenty-three patients (42%) experienced non-fatal major complications. Actuarial 3- and 5-year survival rates from the time of completion pneumonectomy were 48.4 and 35.2% for the entire group. Three- and five-year survival for patients with bronchogenic carcinoma were 56.9 and 43.4%, respectively. Conclusions: These results suggest that completion pneumonectomy in the setting of lung malignancies can be done with an operative risk similar to the one reported for standard pneumonectomy. In contrast, in cancer patients, completion pneumonectomy for inflammatory disorders is a very high-risk procedure. (C) 2003 Elsevier B.V. All rights reserved.
