CRP and breast cancer: determined specific combinations involving lymphocyte count, PLT, neutrophil-to-lymphocyte ratio (NLCR), mean platelet volume (MPV), MPV-to-PLT ratio (MPV/PLT), platelet-to-larger cells ratio (P-LCR), and C-reactive-protein (CRP), and obtained a good ability to distinguish various pathogens in BSI from negative BC.
