Surgical treatment of primary sarcoma of the lung.
OBJECTIVE
To study the results of surgical treatment of primary lung sarcoma.


METHODS
Between 1982 and 1998, we performed 18 macroscopically complete resections for primary sarcomas of the lung. The records of all patients were reviewed, as were pathological slides. Presence of symptoms, tumour size (more or less than 5 cm), complete resection, TNM stage and histology grade were analyzed for predictors of survival.


RESULTS
Patients comprised 11 women and seven men whose age ranged from 19 to 73 years (mean 50 years). Mean tumour diameter was 8.05 cm (range 2.5-15 cm) There were one grade 1, eight grade 2 and nine grade 3 tumours. Tumours in two patients were unresectable at first presentation, and another was of doubtful resectability according to computed tomography scan. These three patients received pre-operative chemotherapy, with a partial response in the two unresectable patients allowing macroscopically complete resection in both cases. We performed 12 lobectomies (extended to the chest wall in two cases and to the diaphragm in two cases) and six pneumonectomies (extended to the chest wall in one case and the superior vena cava in one case). Operative and 30 days post-operative mortality were nil. Resection margins were invaded in two cases. Six patients received post-operative chemo- or radiotherapy and three others underwent repeat resections for pulmonary sarcoma recurrence. No patients were lost to follow-up. Pulmonary sarcomas recurred in eight patients (44%) leading to death in five cases after a mean period of 17 months. Overall median survival was 48 months, and actuarial 5-year survival 43%. Only TNM stage correlated with significantly increased survival.


CONCLUSIONS
As complete resection is the best therapeutic option for obtaining an acceptable survival rate in primary pulmonary sarcoma, pre-operative chemotherapy can be a useful adjunct in increasing the resectability of these tumours.
