Long-Term Results for Clinical Stage IA Lung Cancer: Comparing Lobectomy and Sublobar Resection

In an enhanced national dataset representative of outcomes for stage IA NSCLC, sublobar resection was associated with a 39% increased risk of cancer recurrence. The majority of patients treated with sublobar resection had an inadequate lymph node assessment. These real-world results must be considered when existing clinical trial results comparing these treatments are extrapolated for clinical use.
