The biodistribution of a radiolabelled monoclonal antibody (I-NDOG) was studied in patients with ovarian tumour. It was found that the uptake patterns in known tumour sites was variable and that the clearance of the agent from the vascular pool was due to renal excretion of the radionuclide and the redistribution of the radioactively labelled compound into other compartments. The mean (±SD) plasma clearance time was 20.8 (±2.3) h and the ratios of target (tumour) to background (thigh) ranged between 1.4 and 4.8. The ratio between the plasma radioactivity at either 3.5 or 20 h after administration was calculated relative to the initial plasma radioactivity. These values (0.79 and 0.48, respectively) were incorporated into an image-subtraction technique that allowed for redistribution outside the vascular pool. A whole-body dose equivalent to 16.3 μSv MBq (60.4 mrem.mCi) was calculated. [ABSTRACT FROM AUTHOR] |
