FIGURE 1. Kaplan-Meier plot of survival of GBM patients and of all patients after locoregional treatment with 131I-labeled murine 81C6 mAb. Median survival for patients with GBM and for all patients was 69 and 79 wk, respectively. (Reprinted with permission of (18).)
FIGURE 2. Coregistered MRI and 18F-FDG PET images after surgery and as a function of time after treatment with 131I-labeled murine 81C6 mAb. At 5 wk, cavity margins exhibited increased 18F-FDG uptake and enhancement on MRI. Biopsy samples obtained from this patient at 24 and 52 wk showed radiation necrosis and macrophage infiltration but no tumor involvement. (Reprinted with permission of (18).)
FIGURE 3. Axial MR image (gadolinium enhanced, T1 weighted) coregistered with isodose contours for a patient treated with 3,700 MBq of 131I-labeled murine 81C6. Volume of surgically created tumor resection cavity in this patient was 51.2 cm3. (Reprinted with permission of (22).)
