However, a previous study by Correa et al investigated the association of serum alpha 1-glycoprotein concentrations – another APP – with prognosis in cats with lymphoma, although no correlation was found.36 This is in contrast with previous literature on human solid neoplasia, where the serum concentration of SAA at presentation was correlated with a reduced time to progression and survival time.27,37. This evidence concerns the gene APP and lymphoma.
