Corrélation entre la scintigraphie osseuse et le taux du marqueur tumoral CA15-3 dans le cancer du sein. À propos de 100 cas

Abstract

AimTo display the correlation between the rate of tumor marker CA15-3 and the bone scintigraphy for extension or supervision check-up in breast cancer. MethodologyIn this study, we have randomly included 100 patients with a serum dosage of CA15-3 and a bone scintigraphy. ResultsWe compared the results of the bone scintigraphy and the rate of CA15-3. Among the 77 patients with elevated CA15-3, 57 presented a bone scintigraphy exhibiting secondary bone locations. Among 23 patients with a normal rate of CA15-3, 18 women presented a normal bone scintigraphy. The sensitivity of bone scintigraphy was estimated at 91.74%, while the specificity was estimated at 47.37%, and calculating the coefficient, which measures the intensity of linking the two variables, CA15-3 and bone scintigraphy, the Yule coefficient was 0.82. ConclusionIn this study, the intensity of the correlation between bone scintigraphy and the rate of CA15-3 proved very strong.
