Pneumonectomy for lung metastases: indications, risks, and outcome

Area of Science:

• Thoracic Surgery
• Surgical Oncology
• Pulmonary Medicine

Background:

• Pneumonectomy for pulmonary metastases (PM) is infrequently performed.
• The overall benefits and risks of this procedure remain uncertain.
• Limited data exists on the outcomes of pneumonectomy for PM.

Purpose of the Study:

• To evaluate the outcomes of pneumonectomy in patients with pulmonary metastases.
• To identify factors influencing survival and complications after pneumonectomy for PM.
• To assess the feasibility and safety of pneumonectomy in selected cases of PM.

Main Methods:

• Retrospective analysis of 42 patients undergoing pneumonectomy for PM between 1985 and 1995.
• Analysis of patient demographics, primary tumor types (sarcomas, carcinomas, melanoma), indications for surgery, and surgical extent (intrapericardial, extended).
• Evaluation of postoperative outcomes, including mortality, morbidity, recurrence rates, and survival data.

Main Results:

• The study included 42 patients with PM, predominantly from sarcomas (29) and carcinomas (12).
• Indications included pulmonary recurrence (12), centrally located PM (26), and high PM burden (4).
• Postoperative mortality was 4.8%, with major complications in 9.5%. Median survival was 6.5 months, and 5-year survival was 16.8%.

Conclusions:

• Pneumonectomy is not an absolute contraindication for pulmonary metastases (PM).
• However, the study's poor outcomes underscore the need for stringent patient selection criteria.
• Careful consideration of risks versus benefits is essential for patients undergoing pneumonectomy for PM.
