Outcomes of local treatment for local recurrence and second primary lung cancer in residual lobe after segmentectomy for non-small cell lung cancer

Key Points

• This analysis aims to evaluate the outcomes of local treatments for recurrent and second primary lung cancers in the residual lobe post-segmentectomy.
• Retrospective review of 8 cases treated locally from 375 segmentectomy procedures performed between 2008 and 2022.
• Treatment methods included 4 additional lobectomies, 1 segmentectomy, and 3 stereotactic body radiation therapy (SBRT).
• Median observation period post-treatment was 29 months with no perioperative mortality or severe complications reported.
• Pathological diagnoses included 3 cases of local recurrence and 2 cases of second primary lung cancer.
• SBRT was chosen for 2 cases with poor performance status or comorbidities and 1 case with previous lobectomy.
• Overall, local treatment showed acceptable clinical outcomes, with 2 deaths recorded within the observation period.
