The 30-40% of the oncologic patients have pulmonary metastases. Lung can be the only organ affected. In selected patients, exeresis of the pulmonary nodules can mean their healing.Between 1982-1997, twenty two patients presented metastases, 13 could be operated and 16 thoracotomies were done. There were 53% boys and 47% girls whose ages ranged from 3 to 15 years. We have considered: pulmonary tumour location, disease free interval, number of metastases, surgical technique and incomplete pulmonary tumour resection.Primary tumours were: Wilms tumours 23%, bone tumours 67% (Ewing and osteosarcoma). Disease free interval was 2 years in 39%. X-Ray and CT were performed in every case and 66% presented a solitary nodule. Surgical techniques were: metastasectomy in two cases (12%), wedge resection in 8 (50%) and lobectomy in six cases (38%). We made thoracoscopy in two patients. There weren't postoperatory mortality but the patients with tumorectomy had an incomplete surgical resection. The overall survival is 54 percent and the 5 years survival is 23 percent (3 patients).The patients with a DFI 2 years. The pulmonary resection in selected patients can offer better survival. We can use the thoracoscopy in same selected patients.
