Sonographic Score of Tailor et al for Predicting the Risk of Malignancy in an Adnexal Mass

 

Patient selection: woman with an adnexal mass

 

Parameters:

(1) age of the patient in years

(2) time-averaged maximum velocity (TAMXC) on sonography in cm/s

(3) papillary projections

 

Papillary Projections	Points
absent	0
present	1

 

X =

= (0.1273 * (age in years)) + (0.2794 * (TAMXV)) + (4.4136 * (points for papillary projections)) - 14.2046

 

probability of the adnexal mass being malignant =

= 1 / (1 + EXP((-1) * X))

 

Performance:

• The authors reported a sensitivity of 93% and specificity of 90% at a cutoff of 25%.

• According to Aslam et al, the sensitivity was 45% and specificity 93% at a cutoff of 50%.
