The aim of this study was to evaluate the cytogenetic effect of radio-labelled [DOTA, Tyr3 ]octreotate in blood cells in vitro, using the cytokinesis-block micronucleus assay. Blood samples of healthy donors were exposed to different activities of [DOTA, Tyr3 ]octreotate labelled with 131I (n = 3) and 177Lu (n = 3), where radioactive concentration ranged from 600 to 5600 kBq/mL. The cells were cultivated according to criteria adopted by the IAEA (Vienna). The results showed a positive correlation between radioactive concentrations (X) and the frequency of binucleated cells with micronuclei (Y) (P < 0.05). The linear equations were similar: for the 131I labelled, Y = (1.634 ± 0.236) + (0.912 ± 0.137) 10–3 X and for the 177Lu labelled, Y = (1.715 ± 0.342) + (0.743 ± 0.135) 10–3 X.
