Open, thoracoscopic and robotic segmentectomy for lung cancer

Area of Science:

• Thoracic Surgery
• Surgical Oncology
• Pulmonary Medicine

Background:

• Lobectomy is the standard surgical treatment for early-stage lung cancer.
• Sublobar resection, specifically segmentectomy, is being investigated for small tumors.
• Patient selection is crucial for determining the role of segmentectomy.

Purpose of the Study:

• To review and analyze outcomes of open, thoracoscopic, and robotic segmentectomy for early-stage lung cancer.
• To compare segmentectomy with lobectomy in terms of morbidity, recurrence, survival, and lung function.
• To identify patient subgroups who may benefit most from segmentectomy.

Main Methods:

• Systematic review of studies reporting outcomes of segmentectomy (open, thoracoscopic, robotic).
• Analysis of data on morbidity, recurrence, survival, lung function, and exercise capacity.
• Comparison of segmentectomy outcomes with historical or concurrent lobectomy data.

Main Results:

• Segmentectomy demonstrated equivalent rates of morbidity, recurrence, and survival compared to lobectomy for Stage I lung cancer with tumors <2 cm.
• Segmentectomy resulted in superior preservation of lung function and exercise capacity.
• Tumor characteristics (e.g., ground glass opacities) and patient factors (age, cardiopulmonary reserve) influence suitability.

Conclusions:

• Segmentectomy is a reasonable consideration for select patients with early-stage lung cancer (Stage I, tumors <2 cm) who meet specific criteria.
• This approach offers oncologic safety with the added benefit of lung function preservation.
• Ongoing randomized controlled trials will further elucidate the definitive role of segmentectomy in lung cancer treatment.
