Fig. 1 Posterior 111In-girentuximab image of Patient 14 with a small renal mass in the left kidney. An attempt to biopsy the lesion had failed and the patient underwent 111In-girentuximab immunoSPECT. Besides normal uptake in the right upper abdomen (liver and upper gastrointestinal tract), clear targeting of 111In-girentuximab is seen in lesion (arrow). Histopathologic examination revealed a clear cell renal cell carcinoma with a 12-mm diameter.

Fig. 2 Carbonic anhydrase IX (CAIX) expression in a type 2 papillary tumor. CAIX expression was found in a vital tumor region within a necrotic part of the surgical specimen, suggesting hypoxia-driven expression.

Fig. 3 Images from Patient 29, who had a history of clear cell renal cell carcinoma. After tumor nephrectomy, the patient entered active surveillance. (a) On follow-up computed tomography (CT) scan, a 5-mm lesion in segment 8 of the liver was detected, and biopsy of this lesion was nonconclusive. (b) Clear targeting of the liver lesion on the subsequent 111In-girentuximab immunoSPECT was detected. (c) On a follow-up CT scan 2 mo after immunoSPECT, growth of the lesion was detected and systemic therapy was started.
