ABSTRACT
Uterine cervical cancer is one of the most common tumors in women. An estimated 500,000 cases of invasive cancer are diagnosed worldwide each year. Mexico has a high incidence rate 50 cases per 100,000 women. The high incidence reflect the deficiency of early detection programs used. From 1990 to nowadays a plethora of new diagnostic methods have been tried, including fluorescence spectroscopy, improvements in the cytological techniques, as well as molecular biological tests. Cervical intraepithelial neoplasias (CIN) induced by the Human Papilloma Virus (HPV) frequently are not diagnosed by means of the usual techniques. In many medical consulting offices the lack of optimal equipment and of a simple test to diagnose this disease force gynecologists to use laboratory tests that need long waiting time. The aim of this document is the introduction of a new colposcopic system knowns as: actinic light colposcopy that solves the above problems. The new instrument is specifically for diagnose the cervical intraepithelial neoplasia. And its results are obtained at the same moment that the procedure is performed. Comparative results in this study with 106 women shows rates of false-positives 3% and False-negatives 13%, against the rates of “classical colposcopy” with ranges from 4 to 33% false-positive and 40 to 62% false-negatives. Also it is expected that the actinic light will be enhanced with a dispositive for a photodynamic therapy (PDT), so diagnosis and treatment will be accomplished at the same moment that the detections.
