Abstract:

Squamous intraepithelial lesions (SILs) are cancer precursors targeted by secondary prevention of cervical cancer programs that are sometimes difficult to grade accurately. Mena is an actin regulatory protein involved in membrane protrusion, cell motility, in tumor invasion and metastasis. We studied retrospectively 68 cases of patients diagnosed with squamous intraepithelial lesions that received expedited treatment (treatment without colposcopic biopsy). We analyzed demographic, behavioral data, obstetrical and medical history, from the patients’ medical charts and we studied the cervical fragments or cones harvested after the excisional procedure. Our study failed to identify a correlation between SILs and risk factors such as low socioeconomic status, combined oral contraceptive use, intrauterine device use, parity, gravity, except for the tobacco smoking habit that proved to be related to the cervical lesions’ development. Mena was expressed in most of the analyzed SILs and its expression was correlated with lesions’ grade in terms of both area and intensity, suggesting that Mena stains especially abnormal cells and that its expression intensity correlates with the risk of malignant transformation. Further studies are needed to validate Mena as an early stage of cervical carcinogenesis marker.
