Microarray technology was used to profile miRNA expression in primary tumor and stromal
tissue from paraffin embedded material of 51 patients with colorectal cancer. 26 miRNAs
resulted differentially expressed with at least 2‐fold change in tumor tissue with respect to
stroma (16 more expressed in the tumor and 10 more expressed in the stroma). 10/26 were
confirmed as differentially expressed at qRTPCR: miR‐200c‐3p, miR‐141‐3p, miR‐200b‐
3p, miR‐200a‐3p, miR‐1246, miR‐92a‐3p, miR‐194‐5p, miR‐192‐5p, miR‐3651‐5p, and …

No significant association was found between miRNA expressions and stage at diagnosis, site of primary tumor, first site of metastasis, progression‐free, or overall survival.
