With nifedipine infusion during ILP, tumour perfusion substantially increased and resulted in a considerably higher nutrient supply which was reflected by a higher (though not statistically significant) tumour glucose concentration (1.39±0.39 μmol g−1 during nifedipine application vs 0.59±0.09 μmol g−1 in ILP tumours without nifedipine). Here, XIAP is linked to neoplasm.
