Extended segmentectomy is a viable surgical option for small lung tumors (less than 2 cm) in patients without lymph node involvement (N0). This multicenter study

Area of Science:

  • Thoracic Surgery
  • Surgical Oncology
  • Pulmonary Medicine

Context:

  • Multicenter study initiated in 1992 evaluating surgical techniques for small lung tumors.
  • Focuses on extended segmentectomy for peripheral tumors < 2 cm.
  • Compares outcomes with traditional lobectomy and Lung Cancer Study Group data.

Purpose:

  • To assess the efficacy and safety of extended segmentectomy for early-stage lung cancer.
  • To determine suitability of extended segmentectomy for N0 small tumors.
  • To document surgical procedures including lymph node examination and resection margins.

Summary:

  • 55 patients with peripheral lung tumors (< 2 cm) were enrolled in the extended segmentectomy study.
  • Lymph node examination (frozen section) and mediastinal dissection were performed.

  • Resected lung tissue exceeded one segment; five patient deaths occurred from various causes, one with local recurrence.

    • Impact:

    • Interim results suggest extended segmentectomy is appropriate for N0 small lung tumors.
    • Provides evidence for minimally invasive surgical approaches in lung cancer treatment.
    • Highlights the importance of careful margin assessment and lymph node staging.
