Based on lesion location, colorectal carcinoma (CRC) patients (A) miR-221 and (B) miR-18a were categorised into proximal (n=50), distal (n=82) and rectum (n=66). Colorectal neoplasms were classified by three locations as follows: the proximal colon (caecum, ascending, hepatic flexure and transverse), distal colon (splenic flexure, descending and sigmoid and recto-sigmoid junction) and rectum. NS denotes no statistical significance. miRNA levels were expressed in number of copies per nanogram of extracted RNA. Open circles represent samples with an undetectable miRNA level. The lines denote the medians.
