ADNEX model: Stage II - IV
The ADNEX model is a risk prediction model that can reliably distinguish between benign, borderline,stage I invasive, stage II-IV invasive, and secondary metastatic adnexal ovarian tumours. 

This model calculates the probability that a tumour is stage II - IV. 

It is adviced to use the composite model since it provides more extensive prediction of the tumour stage. The composite can be found here: http://www.evidencio.com/public/show/946

Conditional information

The model uses three clinical predictors (age, serum CA-125 level, type of centre) and six ultrasound predictors (maximal diameter of lesion, proportion of solid tissue, more than 10 cyst locules, number of papillary projections, acoustic shadows, and ascites).

Serum CA-125 level and proportion of solid tissue were the strongest predictors.

The ADNEX model has the potential to change management decisionsfor women with an adnexal tumour. This could impact considerably on the morbidity and mortality associated with adnexal pathology.
