ABCA1 and astrocytic tumor: High protein expression of LRP-1 and ABCA-1 was associated with significantly shorter survival when all the astrocytic tumors, including GBM, LGA, and HGA assessed together (Estimated mean OS for LRP-1 – 70.0 vs. 100.3 weeks; Estimated mean OS for ABCA-1– 62.3 vs. 116.2 weeks) (Figures 6B,D).
