Core Tip
Core Tip: The age at which colorectal cancer is first diagnosed is decreasing worldwide, and colorectal cancer, especially in the 40s is very important. In our study, we found that colorectal cancer patients in their 40s had significantly more metastatic lesions and fewer K-ras mutations. Nevertheless, the oncologic outcome was never inferior compared to patients in their 30s and 50s by stages. We believe this to be a very important clinical message in the current situation.
