After that, by a linear regression model, we found a straight-line relationship (from 0.7 up to 0.99) among CENPN, LRP8, DSCC1, CTPS, RCOR2, GINSS4, TUBA1C and PRAME with tumour subtypes and staging, while SLC7A11 and CDCA7 correlated only with subtypes. This evidence concerns the gene CDCA7 and neoplasm.
