Background: To evaluate the role of double lung transplantation (DLT) for lung cancer, the survival outcomes of patients who underwent DLT for lung cancer and the incidence of lung cancer after DLT were assessed. Methods: Data from case series reported in the literature were pooled and collected from the Organ Procurement Transplantation Network (OPTN) and the International Society of Heart and Lung Transplantation (ISHLT) registries. We evaluated the recurrence-free survival (RFS), overall survival (OS), and cancer-specific survival (CSS) of patients who underwent DLT for lung cancer. Moreover, the incidence and OS of post-transplant lung cancer in patients who received transplants for the non-cancerous disease were examined. Results: Regarding patients who underwent DLT for lung cancer, in the pooled (n = 19), OPTN (n = 15), and ISHLT (n = 25) data, 5-year RFS was 52.6%, 66.7%, and 80.0%, and 5-year OS was 57.9%, 26.7%, and 36.0%, respectively. The median CSS was 48.0 (range, 6.0–144.0), 27.7 (range, 0.2–66.6), and 24.0 (range, 0.1–145.1) months. Additionally, the application of cardiopulmonary bypass was associated with lower tumor recurrence in the pooled data (p = 0.004). The incidence and 5-year OS post-transplant lung cancer in patients who underwent DLT for the non-cancerous disease were 0.8% and 47.3% in the OPTN data and 0.6% and 50.7% in the ISHLT data, respectively. Conclusions: We demonstrated that reasonable survival outcomes can be achieved with DLT in patients with bilateral lung cancer. Further studies are required to evaluate the risk of post-transplant lung cancer in patients undergoing DLT for bilateral lung cancer.
