PDGFRA positive vessels were found in 170/324 (52.5%) cases (15/44, 34.1% anaplastic oligodendroglioma; 5/18, 27.8% anaplastic astrocytoma; 150/262, 57.3% glioblastoma); KIT positive vessels in 79/302 (26.2%) cases (8/41, 19.5% anaplastic oligodendroglioma; 2/15, 13.3% anaplastic astrocytoma; 69/246, 28.0% glioblastoma); and VEGFR2 positive vessels in 306/341 (89.7%) cases (41/49, 83.7% anaplastic oligodendroglioma; 12/17, 70.6% anaplastic astrocytoma; 253/275, 92% glioblastoma). Here, KDR is linked to anaplastic oligodendroglioma.
