Lung surgery for metastatic epithelial tumours.

Area of Science:

• Oncology
• Thoracic Surgery
• Cancer Metastasis

Background:

• Pulmonary metastases from epithelial cancers present a complex treatment challenge.
• Surgical resection is a potential therapeutic option for select patients.
• Identifying prognostic factors is crucial for optimizing patient selection and outcomes.

Purpose of the Study:

• To evaluate the outcomes of surgical treatment for pulmonary metastases in epithelial cancers.
• To identify prognostic factors influencing survival after pulmonary metastasectomy.

Main Methods:

• Retrospective review of 61 patients undergoing 76 curative resections of pulmonary metastases (1997-2002).
• Analysis of prognostic factors including disease-free interval (DFI), patient demographics, metastasis characteristics, and surgical variables.
• Statistical analysis to determine factors affecting survival post-metastasectomy.

Main Results:

• Median survival after lung metastasectomy was 36 months.
• Significant prognostic factors for survival included: disease-free interval < 24 months (p=0.0045), unilateral pulmonary metastases (p=0.0062), and no more than one operation (p=0.0065).

Conclusions:

• Resection of epithelial pulmonary metastases can provide significant survival benefits for carefully selected patients.
• A disease-free interval exceeding 24 months is a key indicator for favorable surgical candidacy.
• Unilateral metastases and a limited number of operations are associated with improved outcomes.
• Conventional lung metastasectomy is a safe procedure with low perioperative morbidity and mortality.
