Statistical analysis was performed with χ2 test;
Grading of differentiation status and tumor node metastasis (TNM) classification for colorectal cancer were based on the American Joint Committee on Cancer: Cancer Staging Manual (7th edition, 2009). The tumors were classified into two groups: Well differentiated (grades I and II) and poorly differentiated (grades III and IV).
