[Chances in surgical treatment of bronchial carcinoma under palliative conditions]

Abstract

Palliative surgery aims at symptomatic relief in patients in whom curative therapy seems not feasible. When diagnostic imaging techniques describe advanced stage IIIa, IIIb or IV malignancy, despite of palliative intention curative resection may still be possible. Objective of the present study was to investigate lung cancer patients undergoing surgery with palliative intent and to compare their prognosis with patients whose tumor resection had been complete (R0) or incomplete (R1/R2).

Patients and method: Patients were assigned to one of the three groups on the basis of the following criteria: palliative intention with subsequent complete resection (group I, n = 11); curative intention with subsequent incomplete resection (group II, n = 38), palliative intention with incomplete resection (group III, n = 23). Additionally 3 patients were operated on by explorative thoracotomy. A total number of 75 patients was therefore investigated. Median follow-up period was 34.5 months. Survival rates were calculated using the Kaplan-Meier method.

Results: The following procedures involving resection of pulmonary tissue were performed: pneumonectomy (n = 10), extended pneumonectomy (n = 32), lobectomy (n = 5), extended lobectomy (n = 11), sleeve lobectomy (n = 7), bilobectomy (n = 3), extended bilobectomy (n = 4). The 30 days hospital mortality rate was 13%. Median survival times were 25.5 months in group I, 12.8 months in group II and 7.7 months in group III (statistical significance: group I vs. group II/III, p < 0.05).

Conclusions: Results of the present study show that patients with bronchial carcinoma in advanced tumor stages III and IV may still benefit from pulmonary resection, particularly when reduction of their somatic complaints is considered. In 11 patients, R0 resection was feasible leading to a statistically significant prolongation of their survival rates.
