Aggressive pulmonary resection for metastatic osteogenic and soft tissue sarcomas

Area of Science:

• Surgical Oncology
• Medical Oncology
• Pulmonary Medicine

Background:

• Pulmonary metastases are a common cause of mortality in patients with osteosarcoma and soft tissue sarcoma.
• Surgical resection of isolated pulmonary metastases offers a potential curative option.

Purpose of the Study:

• To evaluate the efficacy of thoracotomy for resection of pulmonary metastases in patients with osteosarcoma and soft tissue sarcoma.
• To identify prognostic factors influencing survival after pulmonary metastasectomy.

Main Methods:

• Retrospective review of 36 osteosarcoma and 25 soft tissue sarcoma patients undergoing 95 thoracotomies for pulmonary metastases resection between 1974 and 1979.
• Analysis of patient survival, correlation with clinical factors, and tumor characteristics like doubling time.

Main Results:

• Complete resection was achieved in most patients, though microscopic disease persisted in some.
• Four-year survival rates for non-synchronous metastases were 44% for osteosarcoma and 35% for soft tissue sarcoma.
• Tumor doubling time greater than 40 days was associated with significantly better survival for both sarcoma types.

Conclusions:

• Resection of isolated pulmonary metastases from osteosarcoma and soft tissue sarcoma is a viable treatment option.
• Patients with pulmonary metastases and a tumor doubling time >40 days have a better prognosis.
• Combined modality treatment (surgery + chemotherapy) should be considered for eligible patients.
