The uterine cervix is the most common cancer site for females. Approximately 52,000 new cases occur annually in Latin America, thus the need to improve efficiency and effectiveness of Cervical Cancer Screening Programs (CCSP) is mandatory to decrease the unnecessary suffering women must bear. This paper is addressing essential issues to revamp the CCSP as proposed by the Mexican official norm. ...

The belief that carcinoma-in-situ of the cervix uteri commonly develops into invasive cancer is based on a variety of evidence including: (i) The similar appearance of the cells in the two lesions; (ii) The observation that some patients in whom carcinoma-in-situ had been diagnosed by biopsy subsequently developed invasive cancer; (iii) The fact that carcinoma-in-situ is more prevalent than inv...

This study was designed to examine the effects of oestradiol (E2) on sperm transport in the swine uterus. The bicornuate swine uterus is optimal for the study of the uterine transport and peristalsis because the influence of various factors can be examined on each uterine horn independently. Forty swine uteri (with or without ovarectomy) were perfused for a period of up to 7 h. Two different E2...

Integrating microdensitometry has been used to quantify the glycoprotein, epithelial membrane antigen (EMA), which is frequently expressed on the cytoplasmic membrane of neoplastic cells of the cervix uteri. The technique was able to identify and quantify the antigen over a wide concentration range and could also be semi-automated using a microcomputer interfaced to the microdensitometer and pr...
