Fascin (encoded by FSCN1) is a globular actin cross-linking protein that is required for the formation of actin‑based cell surface processes, which are critical for cell migration and cell‑matrix adhesion. In the present study, a systematic meta‑analysis and bioinformatics analysis was used to identify clinicopathological or prognostic parameters in patients with colorectal cancer. A total of 17 articles were included in the present study obtained from PubMed, Web of Science, Wanfang data, SinoMed and CNKI databases. Odd ratios (ORs) and the corresponding 95% confidence intervals (CIs) were used to estimate the prognostic significance of Fascin expression in patients with colorectal cancer, and the association between Fascin expression and clinicopathological factors. There was a significant correlation between high Fascin expression and poor overall survival rates in patients with colorectal cancer (OR=0.48; 95% CI, 0.38‑0.60; P<0.000001). The meta‑analysis showed that the expression of Fascin was significantly higher in colorectal cancer tissue compared with the normal mucosa (OR=0.13; 95% CI, 0.10‑0.16; P<0.000001) and adenoma (OR=0.23; 95% CI, 0.15‑0.34; P<0.000001). Fascin expression was also associated with depth of invasion (OR=0.31; 95% CI, 0.19‑0.50; P<0.000001), lymph node metastasis (OR=3.07; 95% CI, 1.72‑5.46; P=0.0001), Dukes stage (OR=0.14; 95% CI, 0.04‑0.46; P=0.001), Tumor‑Node‑Metastasis stage (OR=0.38; 95% CI, 0.21‑0.71; P=0.003) and dedifferentiation (OR=0.42; 95% CI, 0.19‑0.94; P=0.04). According to the bioinformatics analyses, FSCN1 mRNA expression levels were higher in colorectal cancer and adenoma tissues compared with the normal tissues (P<0.05). According to TCGA, FSCN1 mRNA expression was associated with a less favorable prognosis in patients with colorectal cancer as an independent factor (P<0.05), and positively correlated with depth of invasion, microsatellite instability and low serum carcinoembryonic antigen levels in colorectal cancer. Taken together, the results of the present study suggested that Fascin expression is a potential marker of tumorigenesis, aggressiveness and poor prognosis in patients with colorectal cancer.
