[Estradiol receptors in cervical intraepithelial neoplasia and cervico-uterine cancer].

The objective of this study was to know if there is a correlation in contents o (R + E) in biopsies from patients pre and post-menopausal, in normal cervix with cervical intraepithelial neoplasia (NIC) and invasive cancer. Thirty four patients with abnormal cytology; colposcopy was carried out, and two biopsies were taken from the suspicious lesion, they were sent for histopathological study, and for estrogenic receptors; both studies were correlated later. It was seen that (R +/- E) concentration is higher in intraepithelial lesions of low and high degree than in control patients; and it was not so in premenopausal with invasive cancer where (R +/- E) are much lower, as to postmenopausal (R + E) concentration is higher specially in invasive cancer.
