Abstract

OBJECTIVES Sarcoma has a predilection to metastasis to the lungs. Surgical excision of these metastases (pulmonary metastasectomy) when possible has become standard practice. We reviewed the published selection and outcome data. DESIGN Systematic review of published reports that include survival rates or any other outcome data. Survival data were put in the context of those in a cancer registry. SETTING Specialist thoracic surgical centres reporting the selection and outcome for pulmonary metastasectomy in 18 follow-up studies published 1991-2010. PARTICIPANTS Patients having one or more of 1357 pulmonary metastasectomy operations performed between 1980 and 2006. INTERVENTIONS All patients had surgical pulmonary metastasectomy. A first operation was reported in 1196 patients. Of 1357 patients, 43% had subsequent metastasectomy, some having 10 or more thoracotomies. Three studies were confined to patients having repeated pulmonary metastasectomy. PRIMARY AND SECONDARY OUTCOME MEASURES: Survival data to various time points usually 5 years and sometimes 3 or 10 years. No symptomatic or quality of life data were reported. RESULTS About 34% and 25% of patients were alive 5 years after a first metastasectomy operation for bone or soft tissues sarcoma respectively. Better survival was reported with fewer metastases and longer intervals between diagnosis and the appearance of metastases. In the Thames Cancer Registry for 1985-1994 and 1995-2004 5 year survival rates for all patients with metastatic sarcoma were 20% and 25% for bone, and for soft tissue sarcoma 13% and 15%. CONCLUSIONS The 5 year survival rate among sarcoma patients who are selected to have pulmonary metastasectomy is higher than that observed among unselected registry data for patients with any metastatic disease at diagnosis. There is no evidence that survival difference is attributable to metastasectomy. No data were found on respiratory or any other symptomatic benefit. Given the certain harm associated with thoracotomy, often repeated, better evidence is required.
