Expression of fascin in association with p16 and Ki-67 in cervical lesions: immunohistochemical study.

Annual gynecological examination with cervical cancer screening and HPV vaccination ensures the appropriate prevention of the onset and progression of cervical cancer. Currently, efforts are being made to find new diagnostic and prognostic biomarkers. Fascin, an actin-bundling protein, promotes cellular migration. Its overexpression has been observed in many types of squamous carcinomas and was usually correlated with a worse prognosis and metastasis. However, the data on fascin expression in cervical lesions are limited. This study focuses on the quantitative evaluation of fascin expression, the immunoreaction intensity and subcellular localization of fascin expression in low-grade squamous intraepithelial lesions (LSIL), high-grade squamous intraepithelial lesions (HSIL) and squamous cell carcinomas (SCC). Fascin expression was also correlated with the routinely used diagnostic markers p16 and Ki-67. Biopsy specimens (n = 67) of LSIL, HSIL and SCC were taken from adult women in the age range 20-86 years. Fascin expression was detected by immunohistochemical analysis and quantified using morphometric software. Analysis of variance confirmed statistically significant differences in the percentage of fascin-positive cells between the LSIL, HSIL and SCC groups. Finally, the results showed a significant positive correlation between fascin expression and p16 and Ki-67 expression.
