The predicted values of monocyte-derived macrophage assisted invasion and cystatin C levels from the day 0 breast cancer patients (BCP#) were then ranked in order of lowest to highest cystatin C levels (Table 1) or by invasion index (Table 2), with their ranks interspersed with the actual values from the known, tested MDM data used to train the model. This evidence concerns the gene CST3 and breast carcinoma.
