Figure 2. Patients who underwent pulmonary metastasectomy after resection of primary rectal cancer had poorer outcomes than those after resection of primary colon cancer.

(A) The five-year overall survival rate after pulmonary metastasectomy in rectal cancer patients was 55.2% compared to 82.6% in colon cancer patients (p=0.005). (B) The three-year disease-free survival rate after pulmonary metastasectomy in rectal cancer patients was 42.6% compared to 72.5% in colon cancer patients (p=0.04).
