Anatomic segmentectomy for stage I non-small cell lung cancer in the elderly

Area of Science:

• Thoracic Surgery
• Surgical Oncology
• Pulmonary Medicine

Background:

• Anatomic segmentectomy preserves lung function, crucial for elderly patients with non-small cell lung cancer (NSCLC) and compromised cardiopulmonary status.
• Early-stage NSCLC treatment in elderly individuals necessitates balancing surgical cure with functional preservation.

Purpose of the Study:

• To compare the outcomes of anatomic segmentectomy versus lobectomy in elderly patients (>75 years) with stage I NSCLC.
• To evaluate perioperative morbidity, mortality, hospital course, recurrence patterns, and survival rates for both surgical approaches.

Main Methods:

• Retrospective comparison of 78 elderly NSCLC patients undergoing segmentectomy and 106 undergoing lobectomy (2002-2007).
• Analysis of perioperative complications, hospital stay, recurrence, and survival data.
• Statistical analysis to determine significant differences between the two surgical groups.

Main Results:

• Segmentectomy patients experienced lower operative mortality (1.3% vs. 4.7%) and fewer major complications (11.5% vs. 25.5%).
• Tumor size was significantly smaller in the segmentectomy group (2.5 cm vs. 3.5 cm).
• Overall survival and 5-year disease-free survival rates were comparable between segmentectomy and lobectomy groups (p=0.28 and p=0.80, respectively).

Conclusions:

• Anatomic segmentectomy is a safe and feasible surgical option for elderly patients with early-stage NSCLC.
• Segmentectomy is associated with reduced perioperative complications and equivalent oncologic outcomes compared to lobectomy in this patient population.
• This approach supports lung function preservation in older adults with limited life expectancy.
