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

Q: What does this research mean for the field?

Local treatments, including surgery and stereotactic body radiation therapy (SBRT), are safe and effective options for managing local recurrence or second primary lung cancer in the residual lobe after initial segmentectomy for non-small cell lung cancer. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

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.

Implication

Retrospective analysis of local treatment outcomes for lung cancer recurrence in residual lobe, indicating safety and efficacy.
