OBJECTIVES: The extent of surgical resection for early-stage second primary lung cancer (SPLC) in patients with a previous lobectomy is unclear. We sought to compare anatomic lung resections (lobectomy and segmentectomy) and wedge resections for small peripheral SPLC using a population-based database.
METHODS: The Surveillance, Epidemiology and End Results database was queried for all patients with ≤2 cm peripheral SPLC diagnosed between 2004 and 2015 who underwent prior lobectomy for the first primary and surgical resection only for the SPLC. American College of Chest Physicians guidelines were used to classify SPLC. Kaplan-Meier analysis and multivariable Cox regression were used to compare overall survival.
RESULTS: A total of 356 patients met the inclusion criteria with 203 (57%) treated with wedge resection and 153 (43%) treated with anatomic resection. Significantly better median survival was observed with anatomic resection than with wedge resection using a Kaplan-Meier analysis (124 vs 63 months; P < 0.001). With multivariable Cox regression, improved long-term survival was observed for anatomic resection (hazard ratio: 0.44, confidence interval: 0.27-0.70; P = 0.001). Improvement in survival was demonstrated with wedge resection when lymph node sampling was done. Lastly, we calculated the average treatment effect on the treated with inverse probability weighting for a subgroup of patients and found that those with wedge resection and lymph node sampling had shorter long-term survival times.
CONCLUSIONS: Anatomic resections may provide better long-term survival than wedge resections for patients with early-stage peripheral SPLC after prior lobectomy. Significant improvement in survival was observed with wedge resection for SPLC when adequate lymph node dissection was performed.
