Role of gray scale and color Doppler in differentiating benign from malignant ovarian masses

Abstract

Objectives:To evaluate prospectively the relative usefulness of color Doppler and gray scale sonography in differentiating benign from malignant ovarian masses and evaluation of scoring systems Sassone and Alcazar for differentiating benign from malignant ovarian masses.Methods:Study was conducted during the period of Jan 2006 to Oct 2007 in department of obstetrics and gynaecology, New civil Hospital, Surat. The study was conducted mainly with the help of department of radio-diagnosis. The study include 100 patient clinically suspected to have ovarian neoplasm and referred to department of radio-diagnosis where evaluation with Ultrasonography and Doppler was done. The efficacy of scoring systems were evaluated by histopathological examination of mass or fine needle aspiration cytology or presence of malignant cells in ascetic fluid.Results:Sassone's scoring system was able to identify 72 out of 78 benign masses and 18 out of 22 malignant masses.where as Alcazar system with use of colour Doppler was able to identify 75 out of 78 benign and 21 out of 22 malignant ovarian masses. Sensitivity and specificity of sassone is 81.8%,92.3% respectively, where as that of Alcazar is 95.5%, 96.2% respectively.Conclusion:Using both gray scale and colour Doppler in differentiating benign from malignant ovariam masses is giving results with more accuracy and Alcazar system is better performing than sassone's scoring systems.

Evaluation of the alcazar scoring system in differentiating benign from malignant ovarian tumors

“…Alcazar scoring system gave better results due to addition of color Doppler. 1,9 Central flow and low resistance were more consistently associated with malignancy. 1,8 Doppler increased the sensitivity and specificity.…”

“…Alcazar et al had 3 false positive cases (2 cystadenofibroma, 1brenner), 1 6 Alcazar scoring system with 100% sensitivity and 94.9% specificity is considered better than other 4 scoring systems. 1,9 This improvement in the diagnostic performance was because (1) the analytical approach was more statistically accurate, (2) only parameters truly predictors of malignancy were included. Alcazar scoring system gave better results due to addition of color Doppler.…”

“…To arrive at an accurate diagnosis and optimal 1 st line treatment, a noninvasive diagnostic technique became very essential. 4,9,10 Hence various scoring systems have been developed to differentiate benign from malignant ovarian masses.…”
