Results

Left-sided T1 colorectal cancer(CRC) showed significantly higher rates of lymph node metastasis(LNM; left-sided 12.0% vs. right-sided 5.4%, P < 0.05) and lymphatic invasion (left-sided 32.7% vs. right-sided 23.2%, P < 0.05). Especially, the sigmoid colon and rectum showed higher rates of LNM than other locations. Patients with left-sided T1 CRC were younger than those with right-sided T1 CRC , as well as significantly lower rates of poorly differentiated carcinoma/mucinous carcinoma than right-sided T1 CRC.
