Predictors of Recurrence Following Sublobar Resection for Clinical T1N0M0 Non-Small Cell Lung Cancer

Area of Science:

• Thoracic Surgery
• Surgical Oncology
• Pulmonary Medicine

Background:

• Recurrence after sublobar resection for early-stage lung cancer (T1N0M0) is a significant clinical challenge.
• Identifying and addressing modifiable risk factors is crucial for improving patient outcomes.

Purpose of the Study:

• To review and analyze recurrence risk factors following sublobar resection for clinical T1N0M0 lung cancer.
• To focus on disease stage, tumor characteristics, and surgeon-related factors influencing recurrence.

Main Methods:

• Systematic review and analysis of data from randomized trials and retrospective studies.
• Assessment of the impact of tumor biology, stage, surgical margins, and lymph node dissection on recurrence rates.

Main Results:

• Recurrence is multifactorial, influenced by tumor stage, biology, and surgical technique.
• Inadequate surgical margins (less than ≥1 cm or tumor diameter) and incomplete lymph node dissection significantly increase recurrence risk.
• Systematic nodal dissection improves staging accuracy and guides adjuvant therapy decisions.

Conclusions:

• Surgical margins and lymph node dissection are the most critical modifiable risk factors for recurrence after sublobar resection.
• Prioritizing adequate margins and systematic nodal evaluation is essential for optimizing long-term survival.
• Further research is needed on completion lobectomy or adjuvant therapy in high-risk patients.
