Figure 6: and BED in case of 177Lu therapy (upper panels) and 90Y therapy (lower panels). The histograms report mean and 1 SD. 177Lu and 90Y-therapy administer a similar total dose for the specific schemes considered (29.8 GBq in 4 cycles versus 7.4 GBq in 2 cycles, resp.). Conversely, BED is noticeably greater for 90Y because of the lower fractionation. Mean ± SD values are similar, but relevant differences among patients can be found (see also Figure 4).
