Nueva técnica colposcópica para la prevención del cáncer cervicouterino

Abstract

UTERINE CERVICAL CANCER IS ONE OF THE MOST COMMON TUMORS IN WOMEN. AN ESTIMATED 500, 000 CASES OF INVASIVE CANCER ARE DIAGNOSED WORLWIDE 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 HAVEN BEEN TRIED, INCLUDING FLURESCENCE SPECTROSCOPY, IMPROVEMENTS IN THE CYTOLOGICAL TECHNIQUES, AS WELL AS MOLECULAR BIOLOGICAL TESTS. CERVICAL INTRAEPITHELIAL NEOPLASIAS (CIN) INDUCED BY THE HUMAN PAPILLOMA VIRUS(HPV) FRECUENTLY ARE NOT DIAGNOSED BY MEANS OF THE USUAL TECHNIQUES IN MANY MEDICAL CONSULTING OFFICES THE LACK OF OPTIMAL EQUIPMENT AND OF A SIMPLE TEST.CERVICAL INTRAEPITHELIAL NEOPLASIAS 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 COLPÓSCOPIC SYSTEMS KNOWNS AS: ACTINIY LIGHT COLPOSCOPY THE SOLVES ABOVE PROBLEMS. THE NEW INSTRUMENT IS SPECIFICALLY FOR DIAGNOSE THE CERVICAL INTRAE PITHELIAL NEOPLASIA. AND ITS RESULTS ARE OBTAINED AT THE SAME MOMENT THAT THE PROCEDURE IS PERFORMED. COMPARATIVE RESULTS IN THIS STUDY WITH 106 WOMEN SHOWS RATE OF-FALSE-POSITIVE 3% AND FALSE NEGATIVE 13%, AGAINTS RATES OF ”CLASICAL COLPOSCOPY WITH RANGES FROM 4 TO 33 FALSE-POSITIVE 3% AND FALSE -NEGATIVE. ALSO IT IS EXPECTED THAT THE ACTINIC LIGHT WILL BE ENCHACED WITH A DISPOSITIVE FOR A PHOTODYNAMIC THERAPY PDT), SO DIAGNOSIS AND TREATMENT WILL BE COMPLISHED AT THE SAME MOMENT THAT THE DETECTIONS.
