Background The role for repeat pulmonary metastasectomy for colorectal carcinoma has not been well defined. To identify the class of patients who benefit from pulmonary resection of recurrent pulmonary metastases, we herein reviewed our institutional experience. Methods Between 1990 and 2007, 84 patients with pulmonary metastases from colorectal carcinomas underwent complete pulmonary resection, and 22 of them (26%) later underwent complete resection for repeat pulmonary metastasis. Various perioperative variables were investigated retrospectively in these patients to confirm a role for repeat metastasectomy and analyze prognostic factors after repeat pulmonary metastasectomy. Results Overall survival and disease-free survival after repeat pulmonary metastasectomy were, respectively, 61 and 32% at 5 years. On univariate analysis, male gender and less than 1 year of disease-free status after the first pulmonary metastasectomy demonstrated significantly adverse overall survival (p = 0.01 and p = 0.009, respectively). Elevated preoperative serum carcinoembryonic antigen (CEA) level and maximum tumor size larger than 3 cm were also significantly adverse prognostic factors for disease-free survival (p = 0.03 and p = 0.04, respectively). The overall survival curve after repeat pulmonary metastasectomy was almost identical with that after complete resection of the first pulmonary metastasis. Conclusions Patients with more than 1 year of disease-free status after the first pulmonary metastasectomy demonstrated a significantly better overall survival. Normal preoperative serum CEA level and maximum tumor size <3 cm were significantly adverse prognostic factors for disease-free survival. Our data imply that repeat pulmonary metastasectomy might be beneficial as it can salvage a subset of patients with colorectal carcinoma who retain favorable prognostic determinants.
