Radical laser segmentectomy for T1 N0 lung cancer.

Area of Science:

• Thoracic Surgery
• Surgical Oncology
• Pulmonology

Background:

• Non-small cell lung cancer (NSCLC) requires effective surgical treatments.
• Lung-sparing surgical techniques are crucial for preserving respiratory function.
• Minimally invasive approaches are increasingly preferred in thoracic surgery.

Purpose of the Study:

• To evaluate the efficacy and safety of radical laser segmentectomy for T1 N0 NSCLC.
• To assess the oncological outcomes, including local recurrence and cancer-specific mortality.
• To determine the feasibility of parenchyma-sparing resection with complete lymph node dissection.

Main Methods:

• Retrospective analysis of 18 patients with T1 N0 NSCLC treated with radical laser segmentectomy over 40 months.
• The procedure combines anatomical or nonanatomical segmentectomy using neodymium:yttrium-aluminum garnet (Nd:YAG) laser with complete hilar lymph node dissection.
• Focus on parenchyma-sparing resection and achieving clear safety margins, even for deep-seated tumors.

Main Results:

• No local recurrence observed in any of the 18 patients during the follow-up period.
• Zero cancer-related deaths were recorded.
• No major complications were reported, indicating a favorable safety profile.

Conclusions:

• Radical laser segmentectomy is a potentially effective and safe surgical option for early-stage NSCLC.
• This parenchyma-sparing technique allows for radical resection with clear margins while preserving lung tissue.
• Further long-term follow-up is warranted, but initial results suggest it may be a valuable adjunct in lung cancer treatment.
