Lung Metastases: Current Surgical Indications and New Perspectives

Area of Science:

• Thoracic Surgery
• Surgical Oncology
• Pulmonary Medicine

Background:

• Pulmonary metastasectomy is a key treatment for lung metastases, significantly impacting patient survival.
• Surgical management of lung metastases constitutes a substantial portion of thoracic surgery workload.
• Established principles of radical surgery and lymphadenectomy remain crucial for effective treatment.

Purpose of the Study:

• To review the current state of thoracic surgery for lung metastases.
• To outline the fundamental principles and evolving indications for pulmonary metastasectomy.
• To analyze oncological outcomes based on surgical approach, tumor characteristics, and re-intervention.

Main Methods:

• Mini-review of the literature on surgical management of lung metastases.
• Discussion of historical and current surgical principles, including radical resection and lymphadenectomy.
• Analysis of oncological results stratified by surgical technique (open vs. minimally invasive), histology, tumor burden, and repeat surgery.

Main Results:

• Surgical approach (open vs. minimally invasive) impacts oncological outcomes.
• Histological type and number of lung metastases influence survival.
• Re-metastasectomy can yield positive oncological results in select patients.

Conclusions:

• Pulmonary metastasectomy is a vital component of multidisciplinary lung cancer care.
• Adherence to radical surgery and lymphadenectomy principles is essential.
• Future perspectives in thoracic surgery aim to further refine lung metastases treatment.
