Summary
Complete resection during pulmonary metastasectomy for soft-tissue sarcoma offers the best chance of cure. Factors like bilateral metastases and short disease-free intervals negatively impact survival, but repeat surgeries can be curative.
Area of Science:
- Surgical Oncology
- Thoracic Surgery
- Sarcoma Research
Background:
- Pulmonary metastasectomy is the primary curative option for soft-tissue sarcoma lung metastases.
- Prognostic factors influencing outcomes require detailed analysis.
Purpose of the Study:
- To identify prognostic factors for patients undergoing pulmonary metastasectomy for soft-tissue sarcoma.
- To evaluate the success rate and survival outcomes of this procedure.
Main Methods:
- Retrospective analysis of 34 patients who underwent pulmonary metastasectomy for soft-tissue sarcoma (1996-2007).
- Evaluation of survival curves, prognostic factors, and treatment success rates with a median 26-month follow-up.
Main Results:
- Complete resection achieved in 88.2% with no perioperative mortality.
- Median overall survival was 42 months; median disease-free survival was 27 months.
- Incomplete resection, bilateral metastases, and disease-free interval <18 months were adverse prognostic factors.
Conclusions:
- Complete resection is the key determinant of success and survival after pulmonary metastasectomy.
- Bilateral lung metastases and shorter disease-free intervals predict poorer outcomes.
- Repeat metastasectomy demonstrates curative potential in select patients.
