L. Garcia-salinas et al., Uptake of the Re-188(V)-DMSA complex by cervical carcinoma cells in nude mice: pharmacokinetics and dosimetry, APPL RAD IS, 54(3), 2001, pp. 413-418
The uptake of the rhenium-188 (Re-188(V)-DMSA) complex of dimercaptosuccini
c acid by cervical carcinoma cells in nude mice was evaluated. The pharmaco
kinetics and dosimetry calculations in normal rats were also evaluated. The
images obtained in mice did not show significant accumulation in metabolic
organs and the biodistribution studies showed that 3.52 +/- 0.76% of the i
njected activity per gram (n = 4) was taken up by the tumor. This percentag
e produces a cumulated activity of 35.63 +/- 8.40 MBq h and an equivalent d
ose per injected activity of 260 +/- 8.91 mSv/MBq. Pharmacokinetics and dos
imetry of the Re-188(V)-DMSA complex indicate that this radiopharmaceutical
could be evaluated in patients with soft tissue tumors, since the risk of
radiation damage to the kidney or red bone marrow could not be an obstacle
for its application in therapeutic nuclear medicine. (C) 2001 Elsevier Scie
