Background:
In this retrospective study we have compared the results after sleeve lobectomy and pneumonectomy performed for non small cell lung cancer in the period January 1990-December 1995 at the Thoracic Surgery Unit, University Hospital of Siena. Follow-up was updated until December 2000.
Methods:
In that period, 38 patients underwent sleeve lobectomy and 127 underwent pneumonectomy. The bronchoplasty was a full sleeve in 30 patients and a bronchial wedge resection in eight. Systemic nodal dissection was undertaken routinely.
Results:
The 30-day postoperative mortality was 5.2% (2/38) in the sleeve lobectomy group and 3.9% (5/127) in the pneumonectomy group. Postoperative complications occurred in 23.6% of patients in the sleeve lobectomy group and in 23.2% of those in the pneumonectomy group. Local recurrences occurred in 5.2% of patients in the sleeve lobectomy group and in 4.8% of those in the pneumonectomy group. The overall 5-year survival for the sleeve lobectomy group was 38% whereas that for the pneumonectomy group was 25% (p=0.03). Regarding lymph-node involvement, in the sleeve lobectomy group, the 5-year survival for N0, N1 and N2 was 62.5, 17.5 and 12.5%, respectively.
Conclusions:
Our data confirm that sleeve lobectomy, when performed in selected patients with non small cell lung cancer, provides at least similar overall long term survival to that seen after pneumonectomy. Long term result are chiefly related to nodal stage with a significantly lower survival for patients with nodal involvement. As most patients with nodal involvement die from distant metastases, adjuvant treatment, instead of type of resection, would play a major role in prolonging survival.
