Estudio comparativo y aleatorizado para evaluar la calidad de la muestra celular obtenida con la brocha de polietileno vs la espátula de Ayre más el Cytobrush

Abstract

INTRODUCTION: THE PAP SMEAR REMAINS AN EFFECTIVE, WIDELY USED METHOD FOR EARLY DETECTION OF PRE AND CERVICAL CANCER. SINCE ITS INTRODUCTION, AND WITH THE SCREENING PROGRAMS, THE PREVALENCE OF CERVICAL CANCER HAS DIMINISHED TO 70% IN DEVELOPED COUNTRIES. THIS STUDY EVALUATE THE EFFICACY IN THE DETECTION OF CELLS, WE COMPARED THE POLYETHYLENE BRUSH (GROUP «B») WITH THE AYRE SPATULA AND CYTOBRUSH (GROUP «C»). RESULTS:BETHESDA SYSTEM, WE FOUND THAT AUSCUS, AGC AND LSGIL WERE DIAGNOSED MORE FREQUENTLY IN GROUP «B» (P < 0.05), WITH A RELATIVE RISK OF 4.32, 6.17 AND 1.53. INVASIVE CANCER RESULTED TO BE DIAGNOSED MORE OFTEN IN GROUP «C» (P < 0.05). WE FOUND A GREATER PROPORTION OF ENDOCERVICAL, EXOCERVICAL AND MIXED CELLS IN GROUP «B» (P < 0.05). ACCORDING TO THE DISCUSSION: EARLY DETECTION AND PREVENTION OF CERVIX CANCER IS ESSENTIAL IN HEALTH PROGRAMS. IT IS WELL KNOWN THAT SINCE THE EVIDENCE PUBLISHED BY THE COCHRANE REVIEWERS IN GYNECOLOGIC CANCER IN 2002, THE RECOLLECTION OF CELLS HAS NOT BEEN PROVEN TO BE SO EFFECTIVE IN CELL RECOLLECTION WHEN THE AYRE SPATULA IS USED. OUR STUDY SUPPORTS THIS EVIDENCE BECAUSE THE POLYETHYLENE BRUSH RESULTED MORE EFFECTIVE WITH A CONSIDERABLE RELATIVE RISK.
