Background. Primary sarcoma of the lung is a rare tumor. Our purpose was to study survival after resection and prognostic factors, which have been rarely reported.

Methods. In a 24-year period, we performed 20 complete resections and three exploratory thoracotomies only for primary lung sarcomas. One patient declined operation. Mean diameter of resected tumors was 9 cm (range, 4 to 18 cm). There were eight stage IB, eight stage IIB, one stage IIIA, and three stage IIIB. Sixty percent of patients with resected tumors received adjuvant therapy. Age, sex, resectability, tumor size, histologic cell type, stage, and adjuvant therapy were analyzed as predictors of survival.

Results. No postoperative deaths occurred. All 4 patients who had no resection died within 15 months. The 5- and 10-year actuarial survival after complete resection was 48%. The 5- and 10-year actuarial survival in stage IB was 83%, whereas the 4-year actuarial survival in stage IIB was 30% (p < 0.05). Complete resection and stage of disease were the sole significant prognostic factors.

Conclusions. Complete resection of primary sarcoma of the lung, when feasible, can achieve prolonged survival, although almost half of the patients died of metastasis within 2 years of operation. Adjuvant therapy needs to be investigated.
