Integrating Surgery and Ablative Therapies for the Management of Multiple Primary Lung Cancer: A Systematic Review

Background: Multiple primary lung cancer (MPLC) presents clinical challenges due to its biological complexity. While lobectomy remains standard, limited resection and localized ablation offer comparable efficacy. This systematic review evaluates the safety and efficacy of combining surgical and ablative therapies for MPLC. Methods: A comprehensive search of PubMed, Embase, and Web of Science (January 2000-2025) identified studies involving MPLC patients treated with both surgery and ablation, either concurrently or sequentially. Data on ablation efficacy, adverse events, and prognosis were extracted. A meta-analysis was performed when data pooling was appropriate. The methodological quality and risk of bias of the included studies were assessed using the MINORS and ROBINS-I tools. Publication bias was evaluated through funnel plots and Egger's linear regression test. Furthermore, one case report on combination therapy was also included. Results: A total of nine studies met the inclusion criteria and were included in the final analysis. All reported a 100% technical success rate for ablation, efficacy rates exceeding 70%, and adverse event rates ranging from 5.0% to 26.7%. Due to significant heterogeneity among studies, a random-effects model was applied. The meta-analysis yielded a pooled ablation efficacy rate of 97.11% (95% CI: 85.81-100.00%) and a pooled adverse event rate of 14.23% (95% CI: 8.07-20.38%), indicating favorable safety and efficacy of the combined therapy. Conclusions: The integration of surgical and ablative therapies offers a safe and effective strategy for managing MPLC and supports a potential paradigm shift from single-modality treatment toward a more personalized, organ-preserving, and patient-centered approach.
