Objective

Pneumonectomy is not always sufficient for the radical resection of cancer. In the present study, pneumonectomy may be associated with an extended resection of mediastinal or parietal structures. The postoperative risk and the oncologic benefits of such an extended procedure have not been sufficiently demonstrated.

Methods

We have defined “extended” pneumonectomy (EP) as the removal of the entire lung, associated with one or more of the following structures: superior vena cava, tracheal carina, left atrium, aorta, chest wall, or diaphragm. Our clinical database was retrospectively reviewed to identify patients who underwent EP to assess their postoperative morbidity, mortality, and long-term survival.

Results

Between 1998 and 2005, 47 EPs were performed. The “extended” procedure included left atrium resection in 15 patients, combined SVC and carinal resection in 9 patients, aortic resection in 8 patients (in 3 patients with prosthetic replacement), chest wall or diaphragmatic resection in 6 patients, SVC resection in 4 patients, and carinal resection in 4 patients. A partial esophageal muscular resection was performed in 1 patient. Overall 60-day mortality was 8.5 % . Major postoperative complications occurred in 8 patients (17 % ). The 2- and 5-year survival rates for the overall population were 42 % and 22.8 % , respectively. Interestingly, long-term survivors were recorded only in the group of patients who received induction treatment.

Conclusions

Extended pneumonectomy is a feasible procedure with an acceptable risk factor. To improve the selection of patients, all candidates should undergo preoperative mediastinoscopy and induction chemotherapy. In patients with positive response to chemotherapy or stable disease, extended pneumonectomy may afford a radical resection in more than 80 % of cases and may result in a permanent cure in some instances.
