ABSTRACT: Objective: This study was conducted to evaluate the role of
colposcopy in the screening of cervical cancer at the UTH in Conakry. Material
and Methods: We conducted a descriptive study on over a period of 18 months
of from the 1 July 2004 to December 31, 2005 in the CHU of Conakry Any women aged from
25 to 65 years old who has agreed to the screening of cervical cancer by
colposcopy was included. Statistical tests of sensitivity, specificity, and predictive
values positive and negative were computed directly and compare among all
participants. Results: During the study period, we included a total of
9339 women. For all precancerous and cancerous lesions, sensitivity and
specificity were 93% and 64% respectively. With a positive predictive value of
46% and the negative predictive value of 90%, low and
high grade precancerous lesions were found with: a sensitivity of 91%, the
specificity of 64%. The positive predictive
value of 37%, and the negative predictive value of 91% were estimed.
Intra epithelial lesions (LIEBG) low-grade squamous sensitivity was 94%,
specificity of 62%, the positive predictive value of 31%, the negative
predictive value of 95%. For lesions intra epithelial highgrade squamous (LIEHG),
the sensitivity was 85%, 10%, the positive predictive value of 74% specificity,
negative predictive value of 95%. Conclusion: Colposcopy is a reference
method of detection of precancerous lesions of the cervix to promote cancer.
