KRAS and colorectal carcinoma: While NRAS‐mutation(+) CRC and KRAS‐mutation(+) CRC did not show significant difference in term of AJCC stage in this analysis (P = 0.5), NRAS‐mutation(+) CRC still significantly correlated with older age, distal colon, more mucinous component of the tumor, and less lymph vessel invasion (P = 0.02, 0.006, 0.02, and 0.002, respectively).
