Previous reports have demonstrated that repeated surgical resections of resectable hepatic and pulmonary metastases from colorectal cancer contribute to a better prognosis. We retrospectively assessed the outcomes of 19 patients with colorectal cancer who underwent repeated resections of hepatic and pulmonary metastases between February 2007 and February 2017. The median observation period was 69.9 months, and 26 liver and 27 lung resections were performed. The cumulative 5-year survival rates

after resection of the last metastasis was 75.1% and the median disease-free survival after resection of the last metastasis was 34.7 months. Although 7 patients showed recurrence and 4 patients died, 7 patients exhibited long-term survival. Univariate analysis revealed that simultaneous liver and lung metastases were significantly predictor of poor prognosis(p=0.039). Progress of the patients in the present study were comparable to those in previous reports. Therefore, we propose that repeated surgical resection of hepatic and pulmonary metastasis from colorectal cancer could improve patient prognosis. Further studies should examine to identify more accurate prognostic factor with large series.
