Core Tip

Core Tip: It is important to evaluate synchronous liver metastases of colorectal cancer (CRC) and to determine the response to chemotherapy in patients. Based on findings from such, the optimal treatment method is selected for each patient. The scoring system described in the study, created through a combination of radiology and laboratory parameters, can guide treatment. However, we think that it would be more appropriate to discuss the results of this study in the context of other studies conducted with patients with stage IV CRC.
