Scintigraphic evaluation of lymphoma: a comparative study of 67Ga-citrate and 111In-Bleomycin.

Sequential whole-body scans with both 67Ga-citrate and 111In-bleomycin were performed for 14 patients undergoing staging for Hodgkin's disease or other lymphomas. A comparison or these scans gave a sensitivity in detecting the pathologically-proved tumor sites of 84% for 67Ga-citrate and only 56% for 111In-bleomycin. In 12 patients, the gallium scan demonstrated the lesions more clearly; in the others, the uptake of the two radionuclides was equal. In no case was a clinically diagnosed or histologically proved lesion identified by 111In-bleomycin that was not also demonstrated by 67Ga-citrate. 111In-bleomycin does not complement the 67Ga-citrate scan in the scintigraphic evaluation of lymphomas.
