OBJECTIVE: The diagnostic procedures, role of surgery and multimodal treatment for osteosarcoma pulmonary metastases are examined. METHODS: From January 2000 to June 2005, we observed 35 patients with osteogenic repetitions. Patients were studied by total-body computerised tomography (CT) and by thoracic single-photon emission computerised tomography (SPECT). Preoperative histological diagnosis was obtained by CT-guided transthoracic needle biopsy (23 cases) and fibre-optic bronchoscopy (12 cases). RESULTS: Four lower, 6 upper and 2 middle lobectomies were carried out using a thoracotomy approach. Video-assisted thoracoscopy was used in the other 23 patients who underwent 36 wedge resections. CT showed a sensitivity of 86 % and a specificity of 66 %; SPECT had a sensitivity of 80 % and a specificity of 100 %. Twenty-five patients are still living 25 +/- 11 months after the intervention. CONCLUSIONS: SPECT was demonstrated to offer a better result in the individualisation of secondary pulmonary nodules after primary osteosarcoma. The excision of all resectable lung metastases, integrated in a multidisciplinary strategy, offers good results in terms of survival.

Abstract

OBJECTIVE: The diagnostic procedures, role of surgery and multimodal treatment for osteosarcoma pulmonary metastases are examined. METHODS: From January 2000 to June 2005, we observed 35 patients with osteogenic repetitions. Patients were studied by total-body computerised tomography (CT) and by thoracic single-photon emission computerised tomography (SPECT). Preoperative histological diagnosis was obtained by CT-guided transthoracic needle biopsy (23 cases) and fibre-optic bronchoscopy (12 cases). RESULTS: Four lower, 6 upper and 2 middle lobectomies were carried out using a thoracotomy approach. Video-assisted thoracoscopy was used in the other 23 patients who underwent 36 wedge resections. CT showed a sensitivity of 86 % and a specificity of 66 %; SPECT had a sensitivity of 80 % and a specificity of 100 %. Twenty-five patients are still living 25 +/- 11 months after the intervention. CONCLUSIONS: SPECT was demonstrated to offer a better result in the individualisation of secondary pulmonary nodules after primary osteosarcoma. The excision of all resectable lung metastases, integrated in a multidisciplinary strategy, offers good results in terms of survival.
