Pelvic Masses Score (PMS) of Rossi et al for Evaluating a Pelvic Mass in a Woman

 

Patient selection: woman with a pelvic mass

 

Parameters:

(1) Sassone score (from 4 to 15)

(2) serum CA125 in IU/mL

(3) vascularization score

(4) menopausal status

(5) resistance index (RI) for the mass

 

Parameter	Finding	Points
vascularization score	peripheral	1
	central or septal	2
menopausal status	pre-menopausal	1
	post-menopausal	2

 

where:

• The resistance index for benign masses was 0.83 +/- 0.14 and for malignant masses 0.64 +/- 0.15.

• The method for measuring serum CA125 was not given.

 

PMS =

= (Sassone score) * LOG10(serum CA125) * (vascularization score) * (menopausal status score) / (resistance index)

 

Interpretation:

• A score >= 29 indicates a malignant ovarian tumor.

 

Performance:

• The area under the ROC curve was 0.98 in the study population.
