[The combined colposcopic index as a diagnostic method in human papillomavirus infection and cervical intraepithelial neoplasia].
This is a prospective, comparative study of 142 patients of combined colposcopic index according to Reid's criterium and the index used at the Clinics of Colposcopy, Gyn-Ob Hospital "Luis Castelazo Ayala", IMSS. Seventy two patients were studied with the Hospital Index, and 70 with the CCI. This constituted by neatness of peripheral edges, the color, characteristics of vessels and iodine tinction; a score of 0, 1, 2 was given, the sum of which gave a final qualification, and it was traspolated to a colposcopic diagnosis. The CCI correlated with the histological diagnosis in 64 patients (91.42%); while for the Hospital Index it was in 61 cases (84.7%). The indexes showed a good sensitivity (0.95), a high positive predictive value (0.95 vs 0.88), and adequate accuracy (0.91 vs 0.84), as well as a good prevalence (0.90 vs 0.85). It is concluded that the CCI is reliable for the colposcopic diagnosis of human papillomavirus and for CIN.
