A: Cancer-specific survival (CSS) in all patients (Kaplan-Meier method); B: Disease-free survival (DFS) in all patients (Kaplan-Meier method); C: CSS in repeated pulmonary metastasectomy patients (Kaplan-Meier method); D: Kaplan-Meier survival curves for CSS according to repeated pulmonary metastasectomy in colorectal cancer with pulmonary metastases; E: Kaplan-Meier survival curves for CSS according to perioperative chemotherapy in colorectal cancer with pulmonary metstasis; F: Kaplan-Meier survival curves for CSS according to the number of pulmonary metastases; G: Kaplan-Meier survival curves for CSS according to resection type; H: Kaplan-Meier survival curves for CSS according to disease-free interval values; I: Kaplan-Meier survival curves for DFS according to the number of pulmonary metastases. CSS: Cancer-specific survival; DFS: Disease-free survival; DFI: Disease-free interval.
