DESIGN: Observational Research retrospect. LOCATION: Department of Obstetrics and Gynecology, Regional Hospital of Trujillo, January 1994 to April 1997. Material and metods: Review of medical records file Hospital 109 cases of positive cytology and colposcopy 107 cases who had histopathology. RESULTS: The Pap smear, has specificity 50%, sensitivity 80%, with a false positive proportion of 50% and 20% false negatives. Colposcopy has sensitivity 79%, specificity 25%, with a false positive proportion of 75% and 21% false negatives. The positive predictive values for cytology and colposcopy were 58% and 46% respectively. Conclusions: The Pap smear showed little value as a highly specific test for mass screening of CIN, while colposcopy presents adequate sensitivity; you can not establish the reliability when cytology is complemented by colposcopyOBJETIVO: Evaluar la especificidad, sensibilidad y valor predictivo positivo de las pruebas de detección de la neoplasia intraepitelial cervical (NIC) - citología cervicovaginal y colposcopia . compar´sndolas con el diagnóstico final, dado por la Anatomía Patológica. DISEÑO: Investigación observacional, retrospectiva. LUGAR: Departamento de Ginecología y Obstetricia, Hospital Regional Docente de Trujillo, enero 1994 a abril 1997. MATERIAL Y MÉTODS: Revisión de las historias clínicas del archivo del Hospital de 109 casos de citología positiva y 107 casos de colposcopia que tuvieron estudio histopatológico. RESULTADOS: La citología cervicovaginal, presenta especifidad de 50% y sensibilidad 80%, con una proporción de falsos positivos de 50% y falsos negativos 20%. La colposcopia presenta sensibilidad de 79%, especifidad 25%, con una proporción de falsos positivos de 75% y falsos negativos 21%. Los valores predictivos positivos para citología y colposcopia fueron 58% y 46% respectivamente. CONCLUSIONES: La citología cervicovaginal mostró poco valor como prueba altamente específica para detección masiva de NIC, mientras la colposcopia presenta una adecuada sensibilidad; no se puede establecer la confiabilidad cuando se complementa la citología con la colposcopia.Sociedad Peruana de Obstetricia y Ginecología2015-05-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://51.222.106.123/index.php/RPGO/article/view/466The Peruvian Journal of Gynecology and Obstetrics ; Vol. 49 No. 3 (2003); 155-159Revista Peruana de Ginecología y Obstetricia; Vol. 49 Núm. 3 (2003); 155-1592304-51322304-5124reponame:Revista Peruana de Ginecología y Obstetriciainstname:Sociedad Peruana de Obstetricia y Ginecologíainstacron:SPOGspahttp://51.222.106.123/index.php/RPGO/article/view/466/433info:eu-repo/semantics/openAccessoai:ojs.pkp.sfu.ca:article/4662015-08-07T15:18:52Z
